Thermal management system for vehicle

Abstract

The invention relates to a thermal management system for a vehicle. The system comprises a battery line connecting a first radiator and a high-voltage battery core to each other for exchanging heat therebetween and provided with a first pump; a refrigerant line provided with a compressor, an expansion valve, a condenser and an evaporator, through which a refrigerant circulates; an interior coolingline having a second pump and connecting a cooling core of an indoor air conditioner and a first heat exchanger such that the cooling core of the indoor air conditioner exchange heat with the evaporator through the first heat exchanger; an interior heating line having a third pump and connecting a heating core of the indoor air conditioner and a second heat exchanger such that the heating core ofthe indoor air conditioner exchange heat with the condenser through the second heat exchanger; a first battery cooling line provided with a cooling adjusting valve; and a first battery heating line provided with a heating adjusting valve. The system can efficiently manage energy required for interior air-conditioning and cooling/heating of a battery in the automotive thermal management field.

Description

technical field [0001] The present invention relates to a thermal management system for a vehicle that efficiently manages energy required for cooling and heating of an indoor air conditioner and a battery in the field of thermal management of the vehicle. Background technique [0002] In recent years, electric vehicles have become a social issue to realize environmental protection technology and solve problems such as energy depletion. Electric vehicles operate using a motor that receives power from a battery and outputs power. Therefore, the electric vehicle has the advantages of not emitting carbon dioxide, making little noise, and having higher energy efficiency of a motor than an engine, and thus attracts attention as an eco-friendly vehicle. [0003] The core technology for realizing such an electric vehicle is the technology related to the battery module, and in recent years, researches on the weight reduction, miniaturization and shortening of charging time of batte...

AI Technical Summary

Problems solved by technology

[0005] However, energy cannot be effectively managed during operation by the above-mentioned method, so that the cruising range is short, and it is impossible to travel long distances. The driving distance is shortened by 30% when cooling in summer, and the driving distance is shortened by more than 40% when heating in winter. Therefore, in The problem of winter heating, which is not a problem in internal combustion engines, is more serious

When a high-capacity PTC is used to solve the problem of heating in winter, the travel distance is shortened and the cost and weight are too high due to the use of a heater pump.
