Title:
VEHICLE THERMAL MANAGEMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/019340
Kind Code:
A1
Abstract:
Disclosed is a vehicle thermal management system carrying out an active individual cooling system according to a heating value of a battery, thereby enabling the reduction of power of an electric compressor, and enabling the implementation of a high-capacity cooling system in response to the rapid charging of the battery. The vehicle thermal management system comprises: a refrigerant line circulating through a compressor, a condenser, an expansion valve, a chiller; a cooling heat exchanger and a heating heat exchanger provided in an air conditioner case so as to cool air and heat air, respectively; a first coolant line passing through the heating heat exchanger and carrying out heat exchange with the condenser of the refrigerant line; a second coolant line passing through the cooling heat exchanger and carrying out heat exchange with the chiller of the refrigerant line; a radiator enabling heat exchange between a coolant and outdoor air; a third coolant line passing through the radiator and carrying out heat exchange with a battery of a vehicle; and a coolant valve part for controlling the flow of a coolant of the second coolant line so that the coolant flows in series through the chiller, the cooling heat exchanger, the battery.
