Patent attributes
A vehicle-mounted temperature controller includes a low temperature circuit and a refrigeration circuit. The low temperature circuit has a heat generating equipment heat exchanger exchanging heat with heat generating equipment, a radiator, a first heat exchanger, and a three-way valve. The refrigeration circuit has a second heat exchanger discharging heat from the refrigerant to a high temperature circuit to make the refrigerant condense, and the first heat exchanger making the refrigerant absorb heat from the cooling water to make the refrigerant evaporate. The low temperature circuit includes a first partial circuit through which the cooling water flows through the radiator and the first heat exchanger, and a second partial circuit through which the cooling water flows through the heat generating equipment heat exchanger without passing through the radiator and the first heat exchanger. The cooling water circulates simultaneously and separately at these first partial circuit and second partial circuit.
