Description

Technical Field

[0001] The utility model relates to the technical field of aircraft heating systems, in particular to a hot air intake device and an aircraft. Background Art

[0002] When the aircraft is flying at high altitude, the temperature is low, so the cockpit needs to be heated to improve comfort. The front side of the firewall of a small general aircraft is the engine compartment, and the rear side is the cockpit. The heating system uses the high-temperature exhaust of the engine to heat the outside air, and the heated air passes through the firewall into the cockpit.

[0003] In the prior art, an air intake device that penetrates a firewall usually introduces cold air, mixes the introduced cold air with hot air, and then inputs the mixed air into the cockpit. In order to obtain a suitable temperature in the cockpit, a flow regulating device such as a valve body is usually required to regulate and distribute the flow of cold air and hot air. This regulation method results in a more complicated structural design and installation of the aircraft's hot air intake device, which increases the weight of the small general-purpose aircraft and increases the manufacturing cost.
