Title:
VEHICLE HEAT MANAGEMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/090140
Kind Code:
A1
Abstract:
This vehicle heat management system (10) comprises a control unit (90). The control unit (90) can switch operation modes of the vehicle heat management system (10) among a battery cooling mode, a battery warm-up mode, and a heating auxiliary mode. In the battery cooling mode, cooling water cooled by a second refrigerant in a second heat exchanger (82) cools a battery (32) by absorbing heat from the battery (32). In the battery warm-up mode, cooling water where heat has been dissipated from the second refrigerant in the second heat exchanger (82) heats the battery (32) by dissipating heat to the battery (32). In the heating auxiliary mode, the cooling water is heated by the second refrigerant dissipating heat to the cooling water in the second heat exchanger (82), and a first refrigerant is heated by the heated cooling water dissipating heat to the first refrigerant in a first heat exchanger (81).
