Background

At present, in the prior art, a front-end cooling module system is used as a heat exchange element of a three-electric system and a whole vehicle air conditioning system, so that heat to be radiated under various working conditions of a motor, an electric control and a battery is taken away, and the motor, the electric control and the battery pack have a normal working temperature range and excellent performance in the running state and the charging state of the vehicle; and in hot summer, hot air in the vehicle can be taken away, and cool air is provided for the vehicle so as to improve the riding comfort.

At present, the pure electric vehicle is taken as a main technical direction of a new energy vehicle, and the application of the intelligent advanced technology of the pure electric vehicle is deeply loved by users. The front-end cooling module element of the pure electric vehicle comprises a condenser, a low-temperature radiator and an electronic fan. The cooler not only needs to take away the heat of hot air, but also needs to take away the heat of the battery pack in hot summer; the low-temperature radiator is mainly used for radiating heat of the motor, the electric control and the vehicle-mounted charger, the low-temperature radiator can also radiate the battery pack when the ambient temperature is low and the battery pack also needs to radiate a small amount of heat, if the low-temperature radiator is used for radiating the battery pack, an electromagnetic three-way valve is required to be provided in the system to connect the battery pack with the low-temperature radiator for intelligent control, so that the arrangement difficulty of the whole cooling system elements of the front cabin is increased, and the design cost of the system is improved. The design difficulty of each cooling element fixed mounting at sub vehicle frame.

In view of the above requirements, the arrangement of the scheme shown in fig. 1 requires a special structure of the condenser, and the refrigerant is placed at the top end, so that the manufacturing cost of the condenser is increased; the whole cooling module arranged in the scheme shown in fig. 2 cannot be normally and vertically arranged behind the front grille (because most of the low-temperature radiator is shielded by the front anti-collision beam after the conventional vertical arrangement, the air intake of the low-temperature radiator is insufficient), so that the whole cooling module in the scheme shown in fig. 2 can only be obliquely arranged in the front cabin, and the inclination angle must be large enough to meet the air intake requirement of all heat exchange elements, which increases the arrangement difficulty of the front cabin and the design cost of the air ducting device of the whole system.

In summary, the cooling module component of the current pure electric vehicle type has the following defects:

1. the arrangement principle of each cooling element is poor, so that the heat dissipation efficiency of one cooling element is low or a certain element needs to be specially made, and the manufacturing cost is increased;

2. the low-temperature radiator is selected to be arranged in the middle of the foremost end, so that the arrangement difficulty of the front cabin and the design difficulty of fixedly installing each cooling element on the auxiliary frame are increased;

3. select for use the less low temperature radiator of height dimension to arrange at the forefront structure, only satisfy the motorcycle type of two drives, can't compromise four-wheel drive vehicle, and the platformization is relatively poor.
