This summary is illustrative only and is not intended to be in any way limiting. Other aspects, inventive features, and advantages of the devices or processes described herein will become apparent in the detailed description set forth herein, taken in conjunction with the accompanying figures, wherein like reference numerals refer to like elements.

Following below are more detailed descriptions of various concepts related to, and implementations of, methods, apparatuses, and systems related to exhaust enclosures. Before turning to the figures, which illustrate certain exemplary embodiments in detail, it should be understood that the present disclosure is not limited to the details or methodology set forth in the description or illustrated in the figures. It should also be understood that the terminology used herein is for the purpose of description only and should not be regarded as limiting.

Referring to the figures generally, the various embodiments disclosed herein relate to systems and devices of exhaust enclosures, and methods of their installation or provision. For example, an exhaust enclosure, according to any of the embodiments provided herein, can be provided.

An engine system can include an exhaust outlet, which may exhaust heated combustion gas via an exhaust system to an ambient environment. The combustion gas may be heated by the combustion of the engine itself, as well as after-treatment portions of the exhaust system which may heat the exhaust gases to manage emissions. For example, an after-treatment system can include a diesel particulate filter or diesel oxidation catalyst. Accordingly, a temperature of the exhaust may be limited by a potential presence of workers or passengers adjacent to the exhaust, or a presence of materials which are not adapted to the elevated temperatures. In some instances, such aftertreatment portions may be retrofitted on existing vehicles, such that an existing exhaust system is configured having a backpressure, temperature, or other attribute adapted to engine operation. For example, the backpressure and temperature profiles may be adapted to encourage scavenging of exhaust gases from a combustion chamber. Accordingly, an exhaust enclosure of the present disclosure may be configured to decrease a temperature of a flow passing therethrough without generating substantial increases in back pressure associated with other enclosures.

The exhaust enclosure can include an exhaust vent to exhaust combustion gas therethrough. An exhaust portion of the exhaust vent can exhaust such combustion gas as received from a combustion engine. A compartment portion of the exhaust vent can exhaust compartment air from a defined space (e.g., an engine compartment). The combination of the compartment air and the combustion gas can reduce an average temperature at an outlet of the exhaust enclosure, as vented to the atmosphere. The exhaust enclosure can include skirting walls which are open to the air in the engine compartment, but which channel a fluid flow of compartment air from the compartment to the compartment portion of the exhaust vent. The fluid flow of compartment air can conduct heat from the combustion gas through the enclosure walls, further reducing temperature of the exhaust gas prior to its venting. The air of the engine compartment can be circulated according to convection or active cooling (e.g., of a radiator fan) to further encourage heat exchange. Further still, the enclosure walls can define diffuser structures, such as conical diffusers, which further reduce a temperature of a flow of combustion gases passing through the exhaust enclosure without elevating backpressure in excess of a design limit.

As shown in, a thermal management systemincludes an exhaust enclosureconfigured to receive a combustion gas from a combustion engine, the exhaust enclosureenclosed from an environment(e.g., an environment within an engine compartment) by a plurality of enclosure wallsextending from an exhaust portionof an exhaust vent. The exhaust enclosureincludes a plurality of skirting wallsextending from a compartment portionof the exhaust vent. The plurality of skirting wallsare open to the environmentalong a surface opposite from the exhaust vent, the environmentfluidly coupled with the compartment portionof the exhaust vent.

The exhaust enclosureis shown with reference to a first section line. The first section linecan correspond to an opening in an engine compartment to receive the upper portion of the exhaust enclosure. The upper portion of the exhaust enclosure, including the exhaust vent, can vent air to an ambient environmentseparate from an environmentof the engine compartment. References to the upper portion of the exhaust enclosure, like other references to upper, lower, left, right, or so forth, are provided with reference to the figures, and are not intended to be limit the position of the exhaust enclosure. Indeed, the exhaust enclosurecan be oriented or installed in various orientations.

A second section lineis aligned with an inlet configured to receive a combustion gas from a combustion engine. The combustion gas is received into an inlet diffuserhaving a first enclosure wallof the enclosure wallsalong an upper surface thereof. The inlet is obscured by the first enclosure wallas depicted in, but extends through a fourth enclosure wall. A first surface (the inner surface, not depicted) of the first enclosure wallfaces the inlet and the fifth surface of the fourth enclosure wall (e.g., the inlet is formed from an opening in the fourth enclosure wall). The inlet may be viewed in, for example, the bottom view of, or in reference to an exhaust system of the combustion engine in, for example,.

A third section lineis aligned with a lower surface of the skirting walls. The third section linecan extend along a plane, where the lower surface of the skirting wallsextends to a same plane around a periphery of the exhaust enclosure. In some embodiments, the skirting wallscan extend to different heights around the periphery of the exhaust enclosure. That is, the third section linecan be jogged or piecewise in some embodiments. Likewise, other section lines can correspond to either of a plane perpendicular to an axial line from a bottom-most portion of the exhaust enclosureto a top-most portion of the exhaust enclosure, or can include jogged or piecewise portions.

The first enclosure wallincludes (e.g., defines a surface of) an inlet conical diffuserfor the inlet diffuser. Additional portions of the first enclosure wallextend upwards and off normal from the second section line. These additional portions of the first enclosure wallcan define an increase in surface area of the inlet diffuserextending from the inlet towards the exhaust vent. For example, a cross sectional area of the inlet diffusercan increase monotonically extending from the inlet and through at least a portion of a flow path in the inlet diffuser.

The portions of the first enclosure wall, other than the inlet conical diffuser, are shown as slightly convex along a smooth curve which may maintain airflow through the inlet diffuserso as to avoid generating excessive backpressure at an exhaust system fluidly coupled with the exhaust enclosureat the inlet. The inlet conical diffuser, depicted as forming a convex impression along an exterior of the exhaust enclosure, is concave along at least the first surface of the first enclosure wallof the exhaust enclosure. The inlet diffuserincludes the inlet conical diffuseralong with further walls of the exterior walls. The inlet diffuserincluding the inlet conical diffuserextends parallel to and towards the inlet conical diffuser, along at least a portion of an inlet flow path through the inlet diffuser. A cross sectional area of the inlet conical diffusercan increase monotonically from the inlet to the end of the diffuser, the increased cross-sectional area corresponding to a decreased volume within the inlet conical diffuser.

As shown in the perspective view of, the thermal management systemincluding the exhaust enclosurecan be installed within a compartment(e.g., a locomotive engine compartment), according to some embodiments. The upper surface of the exhaust enclosurecorresponding to the portions extending above the first section lineof(e.g., including the upper surface of the exhaust vent) extends from the engine compartment environmentto the ambient environmentexterior thereto. The ambient environmentcan include outdoors or another environment such as a shed or a tunnel. An upper surface of the exhaust enclosurecorresponding to the portions extending above the second section lineand below the first section lineconform to an upper surface of a wall of the engine compartment. In some embodiments, the upper surface or other portions of the exhaust enclosuremay be thermally coupled with an upper or other wall of the engine compartment, such as via metal-to-metal contact, or via a thermal interface applied therebetween, to encourage thermal transfer between the exhaust enclosureand the ambient environment.

An exhaust systemincluding an after-treatment systemis shown along with exhaust pipes. The exhaust pipes can include a vertical stack portionextending to the inlet (not depicted). In addition to the heated combustion gases, an engine of the engine compartmentcan generate further heat which is dissipated via a radiator. The radiatorcan receive engine coolant from the combustion engine and sink heat from the engine coolant to air in the environmentalong a heat exchange surface of the radiator. A fancan circulate the air from the heat exchange surface throughout the engine compartment. For example, the fancan circulate a portion of the air to externally facing vents or the enclosure wallsof the exhaust enclosure. Such vents can include radiator fan vents (e.g., according to ducting for the air flow or a free flow of air within the engine compartment). A vent can include the exhaust ventof the exhaust enclosure. According to such an airflow, diffusers of the exhaust enclosure, such as the inlet diffuseror an outlet diffuser can exchange heat with the environment. For example, the environmentcan absorb heat from the enclosed portion of the exhaust enclosurewhere the temperature of the exhaust gas in the exhaust enclosureexceeds the temperature of the environment. Air in the environmentcan also exhaust through the compartment portionof the exhaust vent. For example, the airflow may be directed, or the engine compartmentcan be maintained at a positive pressure via an air handling system to exhaust the air.

As shown in, an embodiment of the thermal management systemincluding the exhaust enclosureis depicted according to a sectional view. Section lines are repeated fromto provide a general orientation between the figures, although the particular dimensions and relative positions are provided as illustrative and non-limiting. For example, the exhaust enclosureofmay be the exhaust enclosureof, or can vary in some aspects therefrom.

An exhaust ventof the exhaust enclosureincludes an exhaust portionand a compartment portion. The exhaust portionexhausts combustion gas from the combustion engine, as received from the exhaust systemat an inletof the exhaust enclosure. Upon entering the inlet, the combustion gas flows along an inlet flow pathof the inlet diffuser, the inlet diffuserconfigured to receive the combustion gas from the combustion engine (e.g., via the exhaust system). The inlet diffuserincludes a first surface of a first enclosure wall, the first surface facing the inlet. The inlet diffuserincludes a fifth surface of a fourth enclosure wall, the fifth surface extending between the first surface and an edge defining an opening. For example, the edge can be a lower edge of a second enclosure walldefining the inlet diffuser(e.g., separating the inlet diffuserfrom an outlet diffuser). The first surface and the second surface form at least a portion of the inlet flow pathto direct the combustion gas from the inletto the opening.

The outlet diffuserincludes a conical diffuser (referred to as an outlet conical diffuser) extending perpendicular to and towards the exhaust vent(e.g., from the bottom surface of the exhaust enclosure). The outlet conical diffusercan be integral to at least one of a third enclosure wallor fifth enclosure wall(e.g., a fourth or sixth surface thereof, respectively). The outlet diffusercan include the second enclosure wall. For example, the outlet diffusercan abut a third surface on an opposite side of the second enclosure wallas the from the first surface, such that the second enclosure wallcan define a boundary between the inlet diffuserand the outlet diffuser. The outlet diffusercan include a third enclosure wall. The inner face of the third enclosure wall, facing the third surface, may be referred to as a fourth surface. At least the third surface and the fourth surface from at least a portion of an outlet flow pathto direct the combustion gas from the openingto the exhaust vent. For example, the fourth surface can include a concave surface of the outlet conical diffuser.

The unenclosed skirting defines a skirting flow path. The skirting flow pathcan be separated from the inlet flow pathand the outlet flow pathby the enclosure wallsof the exhaust enclosure. In some embodiments, the unenclosed skirting laterally surrounds the perimeter of the exhaust enclosure. For example, the unenclosed skirting can include any number of skirting wallsextending to a plane along the third section line.

A first skirting wallis disposed away from the third enclosure wall, opposite from the second enclosure wall. That is, a seventh surface of the first skirting wallcan face an eighth surface on an opposite side of the third enclosure wallfrom the fourth surface. The exhaust ventcan couple with the seventh surface and the eighth surface, which may also form at least a portion of the skirting flow path. For example, the seventh surface and the eighth surface can direct air from an environment exterior to the inlet diffuserand the outlet diffuserto a compartment portionof the exhaust vent.

At least a portion of the skirting flow pathextends along the third enclosure walltowards the exhaust vent, and onward to the ambient environment. The skirting flow pathcan pass over any of the enclosure walls of the exhaust enclosure. For example, the skirting flow pathcan pass over any of the exterior faces of the enclosure wallswhich are fluidly coupled with the environmentto exchange heat with the environment. Thus, the exhaust enclosurecan exchange heat, along the enclosure walls, between the combustion gas in the enclosed portion of the exhaust enclosureand air which is both exterior to the enclosed portion and interior to the unenclosed skirting. Such an exchange of heat may be aided by the flow of air along the skirting flow pathbetween the compartment environmentand the ambient environment. For example, the compartment portionof the exhaust ventcan exhaust air exterior to the enclosed portion of the exhaust enclosureand interior to the unenclosed skirting.

The outlet diffusercan include perforated bafflesdisposed off-normal from the outlet flow path. For example, the bafflesmay control (e.g., slow or otherwise modulate) the flow of air along the outlet flow path. Such bafflescan further oppose an ingress of foreign objects or debris into the exhaust enclosure. The exhaust ventmay further include a protective element such as a grill, flutter or flap valve, mesh, screen, or louvres to resist such ingress. A protective element of the exhaust ventcan vary from or use a same material as the baffles.

Although such a protective element may resist the ingress of water, some water may enter the exhaust enclosureduring operation. A lower surface of the exhaust enclosurecan include wellsto collect water or other debris. For example, the wellscan extend downward from (or be integral to) the fifth enclosure wall. Further, the flow of combustion gases towards the exhaust ventcan resist ingress of water towards the exhaust systemand, in any case, the heated combustion gases may evaporate at least a portion of water, for expulsion via the exhaust portionof the exhaust vent. The relative elevation of the inlet diffuserrelative to the openingcan prevent water from reaching the inlet. In some embodiments, the wells, or another portion of the exhaust enclosure(e.g., the fifth enclosure wall) can include a drain port which can couple with a drain line, selectively receive a drain plug, or otherwise control a flow of any water in the exhaust enclosure, such as to divert the water from the engine compartment.

provides a detail view of the of the sectional view of the exhaust enclosureof, according to some embodiments. The exhaust enclosureincludes an enclosed portion of the inlet diffuserand an outlet diffuser, extending between an inletand an exhaust portionof an exhaust vent. The exhaust portionof the exhaust ventis fluidly coupled with an interior of the outlet diffuser. An exhaust portionof the exhaust ventis fluidly coupled with the air exterior to the enclosed portion and interior to the unenclosed skirting. The inlet diffuserdefines an inlet flow pathfor the combustion gas, the inlet flow pathextending from an exhaust inletof the inlet diffuserto an outlet diffuser. The outlet diffuserdefines an outlet flow pathextending from the inlet flow pathto the exhaust vent.

The exhaust enclosureincludes an unenclosed portion extending between an environmentand the compartment portionof the exhaust vent. The exhaust portionof the exhaust ventcan be disposed within a concavity of the compartment portion. For example, the compartment portioncan abut the exhaust portionalong the third enclosure wallas shown, and can further abut the exhaust portionalong one or more surfaces normal to the third enclosure wall(e.g., into and out of the page).

The enclosure wallsinclude a first enclosure wallextending to a second enclosure wall, and includes the inlet diffuser. The second enclosure wallincludes a lower edgedefining an opening. A third enclosure wallis shown parallel with the second enclosure wall, but can vary somewhat therefrom, in some embodiments (e.g., may slightly flare). A fourth enclosure wallincludes (e.g., defines) the inlet. A fifth enclosure wallencloses a lower surface of the exhaust enclosurefrom the environmentin the skirting walls. A sixth enclosure wall extends between the fifth enclosure walland the fourth enclosure wall.

The skirting wallscan include a first skirting wallhaving a lower edgeopen to the environment, and can couple with any of various further skirting walls to peripherally surround (or substantially surround) the exhaust enclosure. At least the first skirting wallof the skirting wallscan include a flare to accelerate the third flow exiting the compartment portionof the exhaust vent.

A first surfaceof the first enclosure wallincludes the inner facing of the conical inlet diffuserand other inner portions of the first enclosure wall. The first surfaceof the first enclosure wallextends away from the inlet and towards a second surfaceof the second enclosure wall. The opposite side of the second enclosure wallmay be referred as a third surface. A fourth surfaceis disposed opposite from the third surface. A portion of the fourth surfacemay include an outlet conical diffuserof the outlet diffuser, extending along the outlet flow pathbetween the inlet conical diffuserand the exhaust vent. A fifth surfaceof the fourth enclosure wall, along with the first surfaceof the first enclosure wallare shaped to expand the inlet flow pathfrom the inletto the opening to cause a first reduction in temperature of the combustion gas in the inlet diffuser(e.g., according to the shape of the inlet conical diffuserand other wall portions). That is, the inlet diffusercan include the inlet conical diffuser extending along the inlet flow pathbetween the exhaust inletand the outlet diffuser.

A sixth surfaceof a fifth enclosure wallis shaped to expand the outlet flow pathfrom the openingto the exhaust ventto cause a second reduction in temperature of the combustion gas in the outlet diffuser. For example, the fifth enclosure wallcan include a surface of the outlet conical diffuser(also referred to with reference to the fourth surface). A seventh surfaceof a first skirting wallcan face an eighth surfaceof the third enclosure wall, the eighth surfaceopposite from the fourth surface.

In some embodiments, the second enclosure wallis a perimeter wall of the exhaust ventgenerally, as well as the exhaust portionof the exhaust vent. For example, such a portion is depicted in along the cut line, and can extend, into or out of the page, to the compartment portionof the exhaust vent. The first skirting wallcan define an opposite perimeter wall of the exhaust ventgenerally, as well as the compartment portionof the exhaust vent. Accordingly, the third enclosure wall, which can extend parallel with the second enclosure walland be laterally spaced therefrom, can define a perimeter of the compartment portionof the exhaust vent. Along the cut line, the third enclosure wallcan further define a perimeter of the exhaust portionof the exhaust vent, but does not define a perimeter of the exhaust ventgenerally in the depicted embodiment. For example, the third enclosure wallcan be said to define an internal subdivision of the exhaust vent.

provides a perspective sectional view of the exhaust enclosure, according to some embodiments. The perspective sectional view is provided along a cut line along an enclosed portion of the exhaust enclosure. Accordingly, although skirting wallsincluding the first skirting walland a second skirting wallon an opposite side of the exhaust enclosureare depicted, some skirting wallsare not visible. For example, further skirting wallscan be disposed forward of the cut line (extending out from the page) and rear of the depicted surfaces (extending into the page). For example, the skirting wallscan substantially surround the exhaust enclosure along a plane or other surface, such as between the second section lineand the third section line.

The perspective sectional view includes a cavity along an exterior surface of the exhaust enclosure, corresponding the inlet conical diffuser. The view also includes an interior surface of the exhaust enclosure, corresponding the outlet conical diffuser(e.g., integral to or coupled with the third enclosure wallor fifth enclosure wall).

A radiatorand radiator fanassembly are shown, along with ducting (including the fan shroud) to fluidly couple the radiator fanwith the exhaust enclosure. The depicted engine assembly can be disposed in an engine compartmentof a locomotive or genset.

In some embodiments, multiple instances of the engine assemblycan be included in a locomotive or genset assembly. For example, a second engine assembly (not depicted) may be oriented substantially mirroring the depicted assembly, so that the depicted exhaust enclosureand a second exhaust enclosure (not depicted) are disposed on opposite ends of the compartment(e.g., the locomotive engine compartment).

As shown in, a bottom view of the exhaust enclosureis provided according to some embodiments.
