  • Publication number: 20210280925
    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.

  • Patent number: 10906141
    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.

  • Publication number: 20190204014
    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.
