[0002] With the development of electric vehicles, the improvement of driving range and energy conversion efficiency is particularly important, which requires a more refined design of the thermal management strategy of the vehicle under different driving conditions. The active air intake grille has become an effective means of finely adjusting the intake volume. However, many models on the market use an active air intake grille directly set on the front bumper, which is an external active air intake grille. Since the air intake grille is exposed and is an exterior part, the change in the shape of the front grille will require the active air intake grille to be redesigned, so its versatility is poor.
[0003] In addition, the cooling modules of most existing vehicle models are arranged vertically, and are matched with a vertically arranged rear air duct structure, so that the incoming air diffuses almost vertically and too sharply through the rear air duct, resulting in less air volume in the upper part of the cooling module and uneven air volume distribution above and below the cooling module. The cold zone module needs to be arranged tilted toward the rear of the vehicle, and the matched rear air duct needs to be rearranged. Utility Model Content
