Description

Vehicle front end module and vehicle Technical Field The application relates to the technical field of vehicle front end modules, in particular to a vehicle front end module and a vehicle. Background At present, the heat dissipation technology of the front end of a vehicle depends on the speed of the vehicle, the windward and the cooling fan, so that the air flow entering from the front grille and used for heat dissipation has passivity, especially under the low-speed working condition, the heat dissipation efficiency is reduced, the air flow on the surface of the radiator is unevenly distributed, and the conditions of dead zone and hot spot exist, so that the overall heat exchange efficiency and the part reliability of the front end module of the vehicle are affected. Based on the existing problems of dead zone and hot spot, on one hand, the heat radiation performance of the front end of the vehicle is unstable under severe working conditions. For example, under extreme working conditions such as high temperature in summer and urban congestion, the heat source load of an engine is large, the forward wind speed of a vehicle is low, and at the moment, the performance bottleneck of the traditional heat dissipation system is particularly prominent, so that the problems of overheating of the engine, reduction of refrigerating efficiency of an air conditioner and the like can be caused. On the other hand, the design space of the heat dissipation system is limited. For example, to address the high load heat dissipation requirements, conventional approaches tend to increase the heat sink area, increase fan power, or increase fin density. However, the front end of the vehicle is directly increased in volume, weight and power consumption of the fan, which is contrary to the development trend of light weight and energy saving of automobiles, and occupies valuable whole vehicle layout space. In addition, due to the fact that the automobile is attractive in appearance, the electric car in winter in cold areas keeps warm, and the like, the effective opening area of the front grille is often insufficient, and the front radiator is insufficient in heat dissipation. Or in order to give consideration to the fact that heat dissipation in summer is sufficient, the front grille opening is large, excessive cold air can be gushed into the front end module when the vehicle runs in winter, wind resistance is increased, the engine compartment and cooling liquid are supercooled, rapid temperature rise of the engine to the optimal working temperature is not facilitated, and warm-up energy consumption of the fuel vehicle is increased or winter cruising of the electric vehicle is directly influenced. Therefore, there is a need for a vehicle front end module and a vehicle that solve the above problems.
