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. ## Claims ### Claim 1 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. ### Claim 2 (canceled) ### Claim 3 (depends on 1) The device temperature regulator according to claim 1, wherein the first condenser includes a plurality of the first heat exchange passages and the second condenser includes a plurality of the second heat exchange passages, and at least one of the plurality of the first heat exchange passages included by the first condenser and the plurality of the second heat exchange passages included by the second condenser, extend along the gravitational direction. ### Claim 4 (depends on 1) The device temperature regulator according to claim 1, further comprising: a collection portion in which the working fluid flowing in the first liquid-phase passage and the working fluid flowing in the second liquid-phase passage collect; and a third liquid-phase passage that has one end connected to the collection portion and that has another end connected to the evaporator and in which the working fluid collected at the collection portion flows to the evaporator, wherein when a length of one of the first liquid-phase passage or the second liquid-phase passage, whose position connected to the first condenser or the second condenser, is higher in the gravitational direction, is denoted by La and a length of the third liquid-phase passage is denoted by Lb, a relation of La and Lb is La
