Title:
VEHICULAR HEAT MANAGEMENT SYSTEM
Document Type and Number:
Japanese Patent JP2023104539
Kind Code:
A
Abstract:
To attain both of a function for obtaining high cooling performance by using a heat pump and a function for obtaining high electric power consumption performance through exhaust heat recovery in a vehicular cooling system for cooling a plurality of heating elements.SOLUTION: A vehicular heat management system includes: a first cooling circuit 4 cooling a first heating element 1; a second cooling circuit 8 for cooling a second heating element 5; a third cooling circuit 12 for cooling a third heating element 9; a first heat exchanger 13 exchanging heat between the third cooling circuit 12 and the first cooling circuit 4; and a second heat exchanger 14 exchanging heat between the third cooling circuit 12 and the second cooling circuit 8. The third cooling circuit 12 includes: a compressor 11 compressing a refrigerant; an expander 10 expanding the refrigerant; and a path switching mechanism for switching a refrigerant circulation path. The vehicular heat management system further includes: a refrigerant driving body 16 for circulating the refrigerant in the third cooling circuit 12; and a main controller 50 controlling the path switching mechanism.SELECTED DRAWING: Figure 1
