Abstract: A thermosiphon applied to a moving body includes a condenser and a plurality of coolers. Each of the plurality of coolers includes a first flow channel forming member, a second flow channel forming member, and a third flow channel forming member. The second flow channel forming member defines a refrigerant inlet that is located below a center portion of a supply flow channel defined by the first flow channel forming member in a vertical direction. The plurality of coolers are arranged along a traveling direction of the moving body and the supply flow channel is fluidly connected in series with each other.

Abstract: A first thermosiphon circuit includes a first evaporator configured to cool a first target device by a latent heat of evaporation of a working fluid that absorbs a heat from the first target device, and a first passage communicating with the first evaporator. A second thermosiphon circuit includes a second evaporator configured to cool a second target device by a latent heat of evaporation of a working fluid that absorbs a heat from the second target device, and a second passage communicating with the second evaporator. A main condenser includes a first heat exchanger provided in the first passage and a second heat exchanger provided in the second passage, and is configured to allow the working fluid flowing through the first heat exchanger, the working fluid flowing through the second heat exchanger, and a predetermined cold energy supply medium to exchange heat with each other.

Abstract: An evaporator includes a fluid chamber in which a working fluid flows. A condenser includes a gas-phase portion in which the working fluid evaporated in the evaporator flows and a liquid-phase portion in which the working fluid from the gas-phase portion, condensed by heat exchange with an external medium, flows. A gas-phase passage causes the working fluid evaporated in the evaporator to flow to the condenser. A liquid-phase passage causes the working fluid condensed in the condenser to flow to the evaporator. A bypass passage has one end connected to the liquid-phase portion of the condenser or the liquid-phase passage and another end connected to the gas-phase portion of the condenser or the gas-phase passage. A flow rate of a liquid-phase working fluid per unit volume in the bypass passage is smaller than a flow rate of a liquid-phase working fluid per unit volume in the liquid-phase portion of the condenser or the liquid-phase passage.

Abstract: A device temperature regulator includes a forward passage in which a forward flow passage is formed to cause a working fluid to flow to a heat absorber from a heat radiator, and a backward passage in which a backward flow passage is formed to cause the working fluid to flow to the heat radiator from the heat absorber. In addition, the device temperature regulator includes a bubble generator, which generates a bubble in the working fluid collecting in the heat absorber and having a liquid phase, and a controller that causes the bubble generator to generate the bubble in a precondition is satisfied.

Abstract: An air conditioner for a vehicle includes a first heat exchanger that exchanges heat between a refrigerant in a refrigeration cycle and a heat medium, a second heat exchanger that exchanges heat between air to be blown into a vehicle interior space and the heat medium, and a casing disposed in the vehicle interior space to form an air passage through which the air flows and to accommodate the second heat exchanger. The first heat exchanger is disposed under the casing, and a partition wall for partitioning an engine room from the vehicle interior space is interposed between the first heat exchanger and the casing.

Abstract: A thermal management system for a vehicle includes a high-temperature side pump that draws and discharges a heat medium, a compressor that draws and discharges a refrigerant in a refrigeration cycle, a high-pressure side heat exchanger that exchanges heat between a high-pressure side refrigerant in the refrigeration cycle and the heat medium circulated by the high-temperature side pump, a heat medium-outside air heat exchanger that exchanges heat between the heat medium circulated by the high-temperature side pump and outside air, and a pump control unit that controls an operation of the high-temperature side pump such that the operation of the high-temperature side pump is continued even after the compressor is stopped. Thus, the cycle efficiency exhibited when restarting the compressor can be improved.
