Automobile comprehensive heat management system

Abstract

The invention discloses an automobile comprehensive heat management system which comprises a motor cooling loop and a battery heat management system, wherein the motor cooling system comprises a firstwater pump, an all-in-one controller, a heat exchanger, a first three-way pipe, a radiator and a first electronic three-way valve which are sequentially connected end to end. A battery heat management loop comprises a battery cooling loop and a battery heating loop, wherein the battery cooling loop comprises a power battery, a second three-way pipe, a second water pump, a heat exchange plate anda second electronic three-way valve which are sequentially connected end to end; and the battery heating loop comprises a power battery, a second three-way pipe, a first electronic three-way valve, afirst water pump, an all-in-one controller, a heat exchanger, a first three-way pipe and a second electronic three-way valve which are sequentially connected end to end. According to the invention, aPTC heater is not required to be additionally arranged on the battery heating loop, and the power battery can be heated and warmed by directly utilizing the existing heat in the whole vehicle, so thatthe advantages of environmental protection and high efficiency are achieved, and the comprehensive control and management can be realized.

Description

technical field [0001] The invention relates to the field of new energy technology, in particular to an automobile comprehensive thermal management system. Background technique [0002] Thermal management technology is one of the core technologies of pure electric vehicles. Its function is to keep components such as drive motors and power batteries within an appropriate temperature range under all working conditions. The thermal management system of a pure electric vehicle usually includes a motor cooling system and a battery thermal management system. The motor cooling system is responsible for cooling the driving motor or the motor controller and other components when the temperature is high. When the temperature of the power battery is heated, it is cooled when the temperature of the power battery is high. Although the existing thermal management system can effectively control and manage the temperature of components such as drive motors and power batteries, it has the f...
