Filed: 2001-01-31
Abstract: PROBLEM TO BE SOLVED: To improve performance without markedly raising the cost. SOLUTION: A refrigerant tank 2 is installed in a flat shape, whose thickness width is smaller than the size (width and height) of a surface, to which a heat radiating element is fitted. A heat sink 5 for increasing a heat radiating area is arranged over the other entire surface. In the heat sink 5, a plurality of heat radiating fins 5a made into sheets are installed perpendicular on the surface of the refrigerant tank 2 by keeping constant intervals and they are extended in the vertical direction of the refrigerant tank 2.
