[0002] As the main means of public transportation, the heating and cooling comfort of vehicles has been paid more attention by more passengers. The vehicle's heating system can realize functions such as heating, defrosting, and adjusting temperature and humidity. Under low temperature conditions, the vehicle's heating system can provide heating to the car, increase the temperature inside the car, and provide a comfortable riding environment for the driver and passengers. When the temperature difference between the inside and outside of the car is large, frost and fog will form on the car window glass, thus affecting the driver's vision. At this time, turning on the heating system can remove the frost and fog on the car window glass to ensure driving safety.

[0003] Existing heating systems often install radiators at the front and rear ends or the top of the vehicle to achieve heating inside the vehicle. However, if the radiator is only installed at the front and rear ends or the top of the vehicle, hot air will gather on the roof and the temperature under the passengers' feet will be lower, which may easily lead to insufficient heating in some local areas of the vehicle. After the heating system is turned on, air flow must last for a long time to meet the overall heating needs of the vehicle, and the temperature control efficiency is low. Utility Model Content
