Title:
VEHICLE HEAT-EXCHANGE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/023941
Kind Code:
A1
Abstract:
The present invention comprises: a strong electric heat exchange circuit; a battery heat exchange circuit; a radiator disposed on the strong electric heat exchange circuit; and a chiller disposed on the battery heat exchange circuit. The radiator includes a first radiator and a second radiator. The strong electric heat exchange circuit includes a first branch circuit connected to the second radiator. The battery heat exchange circuit includes a second branch circuit connected to the second radiator in parallel with the first branch circuit. The first branch circuit and the second branch circuit are provided with a switching means capable of switching a connection state of the second radiator alternately between a first state of connecting to the first branch circuit and a second state of connecting to the second branch circuit. When in the first state, the second radiator performs heat exchange between a refrigerant of the strong electric heat exchange circuit and outside air via the first branch circuit and, when in the second state, performs heat exchange between a refrigerant of the battery heat exchange circuit and the outside air via the second branch circuit.
