Claim:
1. A thermal management system for a vehicle, comprising: a first pump and a second pump, which are adapted to draw and discharge a first heat medium; a first heat exchanger that exchanges heat between outside air and the first heat medium discharged from the first pump or the second pump; a plurality of devices in which the first heat medium circulates; an engine cooling circuit allowing a second heat medium to circulate through an engine; an engine pump adapted to draw and discharge the second heat medium; a second heat exchanger that exchanges heat between the first heat medium and the second heat medium; a first switching valve adapted to switch a flow of the first heat medium, the first switching valve being disposed in a flow path in which a heat medium discharge side of the first pump and a heat medium discharge side of the second pump are connected in parallel with each other, and the plurality of devices and the second heat exchanger are connected in parallel with each other; and a second switching valve adapted to switch a flow of the first heat medium, the second switching valve being disposed in another flow path in which a heat medium suction side of the first pump and a heat medium suction side of the second pump are connected in parallel with each other, and the plurality of devices and the second heat exchanger are connected in parallel with each other, wherein the first switching valve switches between a state in which the first heat medium discharged from the first pump flows, and another state in which the first heat medium discharged from the second pump flows, with respect to the plurality of devices and the second heat exchanger, and the second switching valve switches between a state in which the first heat medium flows into the first pump, and another state in which the first heat medium flows into the second pump, with respect to the plurality of devices and the second heat exchanger.
