A thermal management system for vehicles comprises a thermal medium-thermal medium heat exchanger (18) that exchanges heat between a first thermal medium that is drawn in and discharged by a first pump (11) and a second pump (12) and a second thermal medium that circulates in an engine cooling circuit (40). A first switching valve (19) switches, for each of a plurality of devices (14, 15, 16, 17, 44, 70, 71, 74, 75, 76) and the thermal medium-thermal medium heat exchanger (18), between having the thermal medium discharged from the first pump (11) flow in and having the first thermal medium discharged from the second pump (12) flow in. A second switching valve (20) switches, for each of the plurality of devices (14, 15, 16, 17, 44, 70, 71, 74, 75, 76) and the thermal medium-thermal medium heat exchanger (18), between having the first thermal medium flow to the first pump (11) and having the thermal medium flow to the second pump (12). |
