The projection device includes a closed accommodating space, and a heating element, a cooling element, and an active dehumidification unit that are located inside the closed accommodating space. The heat dissipation control method includes the following steps: obtaining specification temperature information by a specification temperature information obtaining unit, and determining a specification temperature of the cooling element according to the specification temperature information; sensing an ambient temperature and an ambient humidity inside the closed accommodating space by a temperature and humidity sensing unit, and calculating a dew point temperature according to the ambient temperature and the ambient humidity; obtaining a cold end temperature of a cold end surface by a temperature sensing unit; and determining, based on the dew point temperature, the specification temperature, and the cold end temperature, whether to turn on or off the active dehumidification unit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Projection device and heat dissipation control method","description":"A projection device and a heat dissipation control method are provided.
