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 flow path switching device includes: a first passage portion; a second passage portion; a first cover member attached to the first passage portion; and a second cover member attached to the second passage portion. The first passage portion includes a first passage connected to a fluid circuit and having a groove shape. The second passage portion includes a second passage connected to the fluid circuit to communicate with the first passage at a plurality of places and having a groove shape. The first passage portion, the second passage portion, and a drive unit are stacked in this order. The first cover member includes: a sealing portion to seal an opened portion of the first passage; and an opening arranged along an outer edge of the opened portion of the first passage.

Abstract: A thermal management system includes a high-temperature side heating medium circuit, a low-temperature side heating medium circuit, a device heating medium circuit, a circuit connection portion and a circuit switch unit. The circuit switch unit switches between an operation mode in which a heating medium that passed through the low-temperature side heating medium circuit is circulated through any one of the high-temperature side heating medium circuit and the device heating medium circuit via the circuit connection portion and an operation mode in which the high-temperature side heating medium circuit, the low-temperature side heating medium circuit, and the device heating medium circuit are connected via the circuit connection portion, and the heating medium is circulated through a heat generation device, a device heat exchange unit, a heating unit, and a heater core.
