Background technique

The front-end cooling module of the automobile includes a condenser, a radiator, a cooling fan, and upper and lower windshields arranged on the radiator. During the operation of the vehicle, the wind in front of the vehicle is sucked into the engine compartment by the cooling fan. After this part of the wind passes through the cooling module, it absorbs a large amount of heat emitted by the cooling module, and the temperature is significantly higher than the ambient temperature. This part of the hot air will return to the front of the cooling module through the gaps between the upper and lower ends and the left and right sides of the cooling module, and is sucked in for cooling again. However, due to the high temperature of this part of the hot air, the heat cannot be exchanged with the condenser, so that the heat of the condenser cannot be taken away, resulting in a decrease in the heat exchange performance of the condenser. Moreover, the existing front-end cooling module is only provided with an upper wind deflector and a lower wind deflector, which cannot fully realize the wind-shielding effect and affects the heat exchange performance of the condenser.
