THERMAL MANAGEMENT SYSTEM OF VEHICLE

Title:

THERMAL MANAGEMENT SYSTEM OF VEHICLE

Document Type and Number:

WIPO Patent Application WO/2021/133134

Kind Code:

A1

Abstract:

The present invention relates to a thermal management system of a vehicle, in which, through a refrigerant-cooling water chiller and flow control of a refrigerant and cooling water, flow paths of the refrigerant and the cooling water and thermal energy are effectively managed, thus being able to improve cooling/heating performance without separate energy consumption. Thus, the objective of the present invention is to simultaneously achieve the effects of improving cooling/heating performance inside a vehicle and improving fuel efficiency of a vehicle. To achieve the above objective, the present invention provides a thermal management system of a vehicle, comprising: a heat-pump-type refrigerant circulation line comprising a compressor, a high-pressure-side indoor heat exchanger, an expansion valve for a heat pump mode, an outdoor heat exchanger, an expansion valve for an air conditioner mode, and a lower-pressure-side indoor heat exchanger; and a cooling water circulation line for circulating cooling water between a radiator and a specific object to be cooled, the system further comprising a refrigerant-cooling water chiller for heat exchange between a refrigerant in the refrigerant circulation line that is transferred from the outdoor heat exchanger to the side of the low-pressure-side indoor heat exchanger, and cooling water in the cooling water circulation line that circulates the specific object to be cooled.
