Claim:
1. A vehicle thermal management system comprising: a first pump and a second pump drawing and discharging a heat medium; a heat medium heat exchanger that exchanges heat between the heat medium and outside air; a plurality of temperature adjustment devices with temperatures adjusted by the heat medium, each of the temperature adjustment devices having a flow path that allows the heat medium to flow therethrough; a first switching valve that switches an inflow state of the heat medium flowing into each of the temperature adjustment devices between one state in which the heat medium discharged from the first pump flows to the temperature adjustment devices, and another state in which the heat medium discharged from the second pump flows to the temperature adjustment devices, wherein 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 respective heat medium inlet sides of the temperature adjustment devices are connected in parallel with each other; a second switching valve that switches an outflow state of the heat medium from each of the temperature adjustment devices between one state in which the heat medium flowing out of the temperature adjustment devices flows to the first pump, and another state in which the heat medium flowing out of the temperature adjustment devices flows to the second pump, wherein 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 respective heat medium outlet sides of the temperature adjustment devices are connected in parallel with each other; and a controller that controls operations of the first switching valve and the second switching valve to switch between (i) one circulation state of the heat medium circulating between the first pump and the temperature adjustment devices, and (ii) another circulation state of the heat medium circulating between the second pump and the temperature adjustment devices.
