Device temperature regulator

A device temperature regulator for regulating a temperature of a target device, comprising:

• an evaporator configured to cool the target device by latent heat of evaporation of a working fluid by absorbing heat from the target device to be evaporated;
• a first condenser that is provided on an upper side in a gravitational direction than the evaporator and that includes a first heat exchange passage to condense the working fluid evaporated in the evaporator by a heat exchange with a first medium outside of the first heat exchange passage;
• a second condenser that is provided on an upper side in the gravitational direction than the evaporator and that includes a second heat exchange passage to condense the working fluid evaporated in the evaporator by a heat exchange with a second medium outside of the second heat exchange passage;
• a gas-phase passage that causes the working fluid evaporated in the evaporator to flow to the first condenser and the second condenser;
• a first liquid-phase passage that extends from the first condenser and that causes the working fluid condensed in the first condenser to flow to the evaporator;
• and
• a second liquid-phase passage that extends from the second condenser and that causes the working fluid condensed in the second condenser to flow to the evaporator, wherein
• the first medium outside of the first heat exchange passage and the second medium outside of the second heat exchange passage have respective temperatures that are capable of setting individually.
