International ClassF28D 015/00Foreign Application Priority Data1994-07-13 JPAbstractA power pack is mounted on the side wall of a refrigerant tank in which the internal pressure is reduced and a refrigerant is held in such a way that a heat transfer panel on which a power element is mounted can contact the refrigerant. The refrigerant boiled and gasified by heat from the contact part of the heat transfer panel 19 is guided into a radiation part planted on the top of the refrigerant tank 11. The radiation part is composed of a plurality of hollow tubular bodies having flat cross sections. The plurality of radiation tubes are laid out in parallel with each other at specified intervals, the upper ends thereof being closed and the lower ends thereof being open to the inside of the refrigerant tank so that the gasified refrigerant is guided thereinto. Here, the natural convection of the air is generated in the up/downward directions by the plurality of the radiation tubes, and the effective heat radiation is achieved thereby. | |
