Vehicular thermal management system including selective heat transfer medium circulation

A thermal management system for a vehicle, comprising:

• a radiator exchanging heat between a heat transfer medium and outside air;
• a first flow path group including a radiator flow path in which the heat transfer medium flows and the radiator is disposed, and a first bypass flow path and a second bypass flow path that allow the heat transfer medium to bypass the radiator
• a cooler cooling the heat transfer medium;
• a heater heating the heat transfer medium;
• a heat transfer medium circulation device through which the heat transfer medium heated by the heater circulates;
• a plurality of devices to be heat-exchanged that exchanges heat with the heat transfer medium;
• a second flow path group including (i) a cooler flow path in which the heat transfer medium flows and the cooler is disposed, (ii) a heater flow path in which the heat transfer medium flows and the heater is disposed, and a plurality of device flow paths in which the heat transfer medium flows and the devices to be heat-exchanged are disposed;
• a first pump and a second pump, sucking and discharging the heat medium into two systems;
• a first circulation portion circulating heat transfer medium in the two systems, discharged from the first pump and the second pump, with respect to the first flow path group;
• and
• a second circulation portion circulating the heat transfer medium in the two systems, with respect to the second flow path group, wherein
• the heat transfer medium circulation device is disposed in the heater flow path, or the heater flow path is connected to an end of a flow path with the heat transfer medium circulation device disposed therein,
• the first circulation portion switches a flow of the heat transfer medium such that one of the heat transfer media for the two systems selectively circulates through the radiator flow path or the first bypass flow path,
• the second circulation portion switches a flow of the heat transfer medium such that the heat transfer media for the two systems selectively circulate with respect to the second flow path group, and
• the first circulation portion and the second circulation portion switch the flow of the heat transfer medium so as to form a first circulation circuit that allows the heat transfer medium to circulate between the second flow path group and the first pump, as well as a second circulation circuit that allows the heat transfer medium to circulate among the first flow path group, the second flow path group, and the second pump.
