Abstract: A method for manufacturing a device temperature controller includes filling an inside of a circuit with working fluid by connecting a filling port of the circuit to a container that stores gas phase working fluid. The circuit constitutes a thermosiphon heat pipe and allows the working fluid to circulate in the circuit. In the filling, the working fluid inside the circuit is cooled by a cooling source. An inside temperature of the circuit is decreased to be lower than an inside temperature of the container, and thereby an inside pressure of the circuit is decreased to be lower than an inside pressure of the container.

Abstract: A refrigeration cycle device has a compressor, a radiator, a decompressor, an evaporator, a heat medium cooling evaporator, a cooling target device, a detector, and a controller. The heat medium cooling evaporator cools a cooling heat medium by performing a heat exchange between the refrigerant decompressed in the decompressor and the cooling heat medium. The cooling heat medium cools the cooling target device. The detector detects a subcooling state of the cooling target device having a temperature lower than or equal to a reference temperature. Upon the detection of the subcooling state in the cooling target device by the detector, the controller increases the degree of superheat of the refrigerant flowing out of the heat medium cooling heat exchanger as compared to the degree of superheat of the refrigerant flowing out of the heat medium cooling heat exchanger when the detector does not detect the subcooling state.

Abstract: A refrigeration cycle device includes a heat pump cycle, a high-temperature heat medium circuit, and a low-temperature heat medium circuit. The low-temperature heat medium circuit includes a plurality of heat absorption devices configured to have a heat absorption amount to be absorbed by the low-temperature heat medium flowing out of a low-temperature heat medium-refrigerant heat exchanger, and a heat absorption adjusting unit configured to change the heat absorption amount of the low-temperature heat medium in the respective heat absorption devices. In the refrigeration cycle device, a flow amount of the refrigerant flowing into the low-temperature heat medium-refrigerant heat exchanger is reduced when the heat absorption adjusting unit changes the heat absorption amount of the low-temperature heat medium in the respective heat absorption devices, and the flow amount of the refrigerant flowing into the low-temperature heat medium-refrigerant heat exchanger is increased when a recovery condition is satisfied.

Abstract: In a device temperature regulator, an evaporator cools a target device by a latent heat of evaporation of a working fluid that absorbs heat from the target device and is evaporated. A first condenser includes a first heat exchange passage that condenses the working fluid evaporated in the evaporator by a heat exchange with an outside first medium. A second condenser includes a second heat exchange passage that condenses the working fluid evaporated in the evaporator by a heat exchange with an outside second medium. A gas-phase passage causes the working fluid evaporated in the evaporator to flow to the first condenser and the second condenser. Furthermore, a first liquid-phase passage causes the working fluid condensed in the first condenser to flow to the evaporator, and a second liquid-phase passage causes the working fluid condensed in the second condenser to flow to the evaporator.

Abstract: A cooler cools a target equipment by evaporation latent heat of working fluid. A cold-heat heat exchanger condenses the working fluid by radiating heat of the working fluid using cold heat of low-temperature and low-pressure refrigerant circulating in a refrigeration cycle. An air-cooled heat exchanger condenses the working fluid by radiating heat of the working fluid using cold heat of outside air. The cooler, the cold-heat heat exchanger, and the air-cooled heat exchanger are connected by a gas pipe and a liquid pipe. An outside air temperature detector detects an outside air temperature. A saturation temperature detector detects a saturation temperature of the working fluid circulating in a thermosiphon circuit. A heat radiation controller controls an amount of heat radiated from the working fluid flowing through the cold-heat heat exchanger so that the saturation temperature of the working fluid becomes higher than the outside air temperature.
