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.
