[0002] With the continuous development of automotive technology, users are spending more and more time inside the vehicle, and the concept of regarding the car as a home is gradually recognized by people. How to create a more comfortable driving and riding environment inside the vehicle, especially how to effectively create a cool environment for the contact area between the human body and the automotive seat in the hot summer, is an issue that people are paying more and more attention to.

[0003] In recent years, comfort systems using seat air conditioning and ventilation devices as high-end applications of vehicle comfort technology have gradually been recognized by the market. Through the fan power module inside the vehicle body, direct blowing or suction is applied to the ventilation circuit inside the seat. Its active seat cooling or heating and ventilation can bring a more direct and rapid driving and riding comfort to the passengers.

[0004] Taking a traditional suction-type ventilation seat as an example, the air in the environment enters the suction fan through multiple ventilation holes in the seat foam. Driven by the rotation of the suction fan impeller, the gas is discharged through the exhaust port, realizing the air exchange on the occupant side seat surface to facilitate the sweating of the occupant's body and keep the occupant's body fresh. However, it often happens that the air exchange effect in the areas on both sides of the occupant's waist and the thighs is poor, and the ventilation experience is not good. In actual use, the vehicle air conditioning system is usually used to cool the cabin to improve the ventilation experience in the areas on both sides of the occupant's waist and the thighs, but this method will result in higher energy consumption and serious energy loss.
