Abstract: A thermal management device for a vehicle includes heat medium circuits, a reserve tank, and a connector. The heat medium circulates through the heat medium circuits separately. The reserve tank is configured to separate an air bubble contained in the heat medium from the heat medium. The connector allows the reserve tank to come in communication with the heat medium circuits selectively. As such, an occurrence of the heat loss in the degassing performed in the reserve tank can be suppressed with the thermal management device for a vehicle including the heat medium circuits.

Abstract: A vehicular heat management system includes a heat medium circuit, a heat source portion, and a device. A heat medium cooling an engine circulates in the heat medium circuit. The heat source portion heats the heat medium. The device is configured to function and heat the heat medium when the heat medium flowing into the device is at or above a predetermined temperature. When the engine is being warmed up, heat generated by the heat source portion is supplied to the device in preference to the engine. According to this, since the heat generated by the heat source portion is supplied to the device in preference to the engine when the engine is being warmed up, the engine can be warmed up early.

Abstract: A thermal management system for a vehicle includes an engine cooling circuit that causes a heat medium to circulate through an engine, and an engine radiator that exchanges heat between the heat medium in the engine cooling circuit and outside air. The thermal management system for a vehicle further includes a switching device that switches between an independent mode in which the heat medium circulates respectively independently through a cooler cooling circuit and the engine cooling circuit, and a communication mode in which the cooler cooling circuit and the engine cooling circuit communicate with each other to cause the heat medium to flow between a chiller and the engine radiator; and a controller that controls an operation of the switching device to switch to the communication mode when a temperature of the heat medium in the engine cooling circuit is lower than a first heat-medium temperature.

Abstract: A controller of a thermal management system for a vehicle controls a first switching valve and a second switching valve to set a battery warming-up state in which a heat medium circulates between a battery-temperature adjustment heat exchanger and a heat-medium heating heat exchanger, and the heat medium does not circulate between a coolant-coolant heat exchanger and a heat-medium heating heat exchanger when both a battery and an engine need to be warmed up. In contrast, the controller controls the first switching valve and the second switching valve to set an engine warming-up state in which the heat medium circulates through between the coolant-coolant heat exchanger and the heat-medium heating heat exchanger while the heat medium does not circulate between a battery-temperature adjustment heat exchanger and the heat-medium heating heat exchanger when a temperature of the battery exceeds a target battery warming-up temperature in the battery warming-up state.
