PURPOSE:To raise radiating performance, and to reduce weight of a system, by providing a radiator which contacts with and separates from a substrate by expansion and contraction of a vessel, and forming the radiator by a radiating plate, a heat receiving plate, and a heat transmitting body for connecting them. CONSTITUTION:When a temperature of an apparatus 1 rises, heat is transferred to an operating fluid 13 through a substrate 2, a support 15 of a good conductor, and a vessel 7. When a temperature of its operating fluid 13 rises, pressure of the inside of the vessel 7 increases, a bellows 8 stretches, a radiator 18 is pressed against the substrate 2, and heat of the apparatus 1 is directly transmitted to the radiator 18 through the substrate 2 and is raidated. When a temperature of the apparatus falls, pressure of the operating fluid 13 drops by the same process, the beloows 8 contracts, the radiator 18 separates from the substrate 2, and radiation ends. This process uses the operating fluid 13 only for making the radiator 18 contact and separate, heat of the apparatus 1 does not pass through a large thermal resistance of the operating fluid 13, and is directly transferred to the radiator 18, therefore, the radiating performance can be elevated remarkably. |
