COOLING SYSTEM FOR PURE ELECTRIC VEHICLE AND VEHICLE

摘要

A cooling system for a pure electric vehicle, comprising an electric drive system cooling circuit (10), an air conditioning system circuit (20) and a power battery system cooling circuit (30). The cooling system further comprises a four-way control valve (40) which is connected between the electric drive system cooling circuit and the power battery system cooling circuit and is used to switch on and off between the electric drive system cooling circuit and the power battery system cooling circuit, and a three-way control valve (50) which is located in the power battery system cooling circuit and which is used to control heat exchange between the power battery system cooling circuit and the air conditioning system circuit. A heat exchange device between the electric drive system cooling circuit and the air conditioning system circuit forms a water cooling condenser (60) of the air conditioning system circuit, and a heat exchange device between the power battery system cooling circuit and the air conditioning system circuit forms a low-temperature cooler (70) used for the power battery system cooling circuit. A heat exchanger module in said cooling system has a simple structure, low interlinkage impact, fully exhibits cooling performance and greatly improves environmental adaptability of the entire vehicle.
