The shutter case has an opening. The fan is configured to exhaust air inside the housing to outside through the opening. The shutter partitions inside of the shutter case into a first chamber communicating with the opening and a second chamber different from the first chamber, and opens and closes the opening by a rotating operation. The fan is arranged on a first chamber side of the shutter case in the housing. The first chamber is a positive pressure region of the fan. The second chamber is a negative pressure region of the fan. The second chamber of the shutter case communicates only with the negative pressure region in the housing. The shutter is provided so that a pressure received from the second chamber is smaller than a pressure received from the first chamber."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Ventilation device, ventilation unit, and power conversion device","description":"A ventilation device of an embodiment includes a housing, a shutter case, a fan, and a shutter.
