THERMAL MANAGEMENT SYSTEM

摘要

A heat medium discharge side of a first pump and a heat medium discharge side of a second pump are connected to a first switching valve in parallel. Heat medium inlet sides of the respective target devices for heat exchange included in a first target device group for heat exchange are connected to a first switching valve in parallel. The heat medium inlet side of the first pump and the heat medium inlet side of the second pump are connected to a second switching valve in parallel. The heat medium outlet sides of the respective target devices for heat exchange included in the first target device group for heat exchange are connected to the second switching valve in parallel. Furthermore, switching is performed between a state of circulation of the heat medium between the first pump and the target device, and a state of circulation of the heat medium between the second pump and the target device.

1. A thermal management system for a vehicle, comprising:
a first pump drawing and discharging a heat medium adapted to cool an internal combustion engine; a second pump drawing and discharging the heat medium; a heat exchanger exchanging heat between outside air and the heat medium discharged from the second pump; a first target device group for heat exchange including a plurality of target devices for heat exchange that exchange heat with the heat medium; a first switching valve connected to a heat medium discharge side of the first pump and a heat medium discharge side of the second pump in parallel, and connected to respective heat medium inlet sides of the target devices for heat exchange included in the first target device group for heat exchange in parallel, the first switching valve switching between (i) a state in which the heat medium discharged from the first pump flows into the target devices for heat exchange included in the first target device group for heat exchange and (ii) a state in which the heat medium discharged from the second pump flows into the target devices for heat exchange included in the first target device group for heat exchange; and a second switching valve connected to a heat medium suction side of the first pump and a heat medium suction side of the second pump in parallel, and connected to respective heat medium outlet sides of the target devices for heat exchange included in the first target device group for heat exchange in parallel, the second switching valve switching between a state in which the heat medium from the target devices for heat exchange included in the first target device group for heat exchange flows into the first pump, and a state in which the heat medium from the target devices for heat exchange included in the first target device group for heat exchange flows into to the second pump, wherein the first switching valve and the second switching valve are cooperatively operated to switch between (i) a state in which the heat medium circulates between the first pump and the target devices for heat exchange included in the first target device group for heat exchange, and (ii) a state in which the heat medium circulates between the second pump and the target devices for heat exchange included in the first target device group for heat exchange.
