Description
Technical Field
The invention relates to an integrated vehicle heat dissipation system and a vehicle, and belongs to the field of whole vehicle thermal management of charging vehicles.

The motor system of the electric vehicle also accumulates heat energy in a starting state, and heat dissipation and cooling are also required. Because the battery and the motor system have different requirements on proper working temperature, the proper working temperature of the battery is 15-30 ℃, and the proper working temperature of the motor system is 60-70 ℃, the battery and the motor system are cooled by adopting different cooling modes: the battery is usually cooled by a compressor, and the motor system is usually cooled by a radiator. When the external temperature is less than 0 ℃, the compressor is difficult to start and cannot refrigerate, so that the battery is also provided with a set of radiator cooling system for realizing cooling and heat dissipation of the battery under the condition of lower temperature.
The Chinese patent publication No. CN103407346A discloses a heat management system for a whole pure electric vehicle, which can effectively meet the cooling requirement of a motor system, the heating and cooling requirements of a battery system and the refrigerating and heating requirements of a passenger cabin. However, the low-temperature radiator of the battery can only be used in a low-temperature environment, and the battery has higher cooling requirement in a high-temperature environment, so that the compressor is adopted to condense and dissipate heat of the battery. The battery cooling system and the motor cooling system in the thermal management system are mutually independent, the low-temperature radiator of the battery is in an idle state under the high-temperature condition, the utilization rate is low, the resource waste is caused, the filtering device is not arranged in the loop, and when impurities exist in the loop, the loop cannot well protect other parts in the cooling loop.
