Abstract

A car heat management system comprises a battery circulating loop, an air conditioner refrigeration loop and a heat management controller, the battery circulating loop comprises a first battery pipeline, a power battery, a battery heat radiator and a heat exchange assembly, and the power battery, the battery heat radiator and the heat exchange assembly are connected to the first battery pipeline. The heat exchange assembly is used for carrying out heat exchange between the battery circulating loop and an external loop. The air conditioner refrigeration loop comprises a first refrigeration pipeline, a second refrigeration pipeline, a fan, a compressor, a condenser and an evaporator, and the compressor, the condenser and the evaporator are connected to the first refrigeration pipeline. The second refrigeration pipeline is connected with the heat exchange assembly, the two ends of the second refrigeration pipeline are connected to the positions, at the two ends of the evaporator, of the first refrigeration pipeline, and the condenser and the battery heat radiator are arranged on the air outlet side of the fan. The heat management controller is used for selectively starting the fan or the compressor to cool the power battery according to the cooling need of the power battery and the environment temperature. The car heat management system is correlated and integrated with a car air conditioning system, the heat load of the air conditioning system can be balanced, and the energy saving effect is good. The invention further relates to a car.

Description

technical field

[0001] The invention relates to the technical field of automobile heat management, in particular to an automobile heat management system and an automobile. Background technique

[0002] With the limitation of air pollution control and national fuel consumption targets, new energy vehicles have attracted more and more attention from the market and enterprises. The cooling thermal management requirements of the new power system motors and batteries are directly related to their power and economy.

[0003] The control of the existing new energy cooling thermal management system mainly adopts separate control; for example, when the temperature of the battery is too high and needs to be cooled, the battery controller BMS controls the start of the water pump in the battery cooling circuit, and then the air conditioner controller controls the start of the heat exchange electromagnetic valve (chiller), which enables the refrigerant in the air conditioning system to e...
