Abstract: A heat management system includes a high-temperature heat medium circuit, a low-temperature heat medium circuit, a circuit connection part, and a circuit switching part. The high-temperature heat medium circuit connects a heat medium and refrigerant heat exchanger and a heater core. The low-temperature heat medium circuit connects a radiator and a heat generation equipment. The circuit connection part connects the high-temperature heat medium circuit and the low-temperature heat medium circuit such that the heat medium can flow in and out. The heat management system is switched by the circuit switching part between an operation mode in which the heat medium heated by the heat medium and refrigerant heat exchanger is circulated through the heater core and an operation mode in which the heat medium heated by the heat generation equipment and the heat medium and refrigerant heat exchanger is circulated through the heater core.

Abstract: A radiator cap is connected to a circulating circuit at a connecting point located upstream of a water pump in a flow direction of coolant and that regulates a pressure in the circulating circuit to be within a predetermined pressure range that is higher than or equal to an atmospheric pressure at the connecting point. A rotary valve is disposed in the circulating circuit at upstream of the connecting point of the radiator cap in the flow direction of coolant. Accordingly, a cavitation is restricted from occurring, and the water pump can perform enough efficiency. A communication passage that has an upstream end and a downstream end connected to the circulating circuit may be disposed instead of the radiator cap. In this case, a pressure regulating valve is disposed in the communication passage.

Abstract: First circulation portions switch a flow of a heat medium such that one of the heat media for two systems selectively circulates through a radiator flow path or a first bypass flow path. Second circulation portions switch the flow of the heat medium such that the heat media for the two systems selectively circulate with respect to a second flow path group. The first circulation portions and the second circulation portions are adapted to switch the flow of the heat medium so as to form a first circulation circuit for allowing the heat medium to circulate among a first flow path group, the second flow path group, and a first pump, as well as a second circulation circuit for allowing the heat medium to circulate among the first flow path group, the second flow path group, and a second pump.

Abstract: A flow passage switching unit includes side-by-side arranged rotary valve parts. The valve part includes a casing, side walls, a peripheral wall, first fluid ports, a second fluid port, a rotary shaft, and a valving element. A flow passage, through which the first fluid ports and the second fluid port selectively communicate, is formed by rotation of the valving element. The unit includes a driving mechanism driving each valving element by its corresponding predetermined rotation angle. The driving mechanism includes one driving source, and a motive power transmission member transmitting rotation motive power of the driving source respectively to the valve parts. Motive power of the driving source is transmitted to each rotary shaft of the valve parts to drive each valving element to a position, which position of the valving element relative to the first and second fluid ports is different from one another among the valve parts.

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.
