Abstract

PURPOSE:To improve the efficiency of fins, by fixing one-terminal parts of many needle shaped fins to the outer surfaces of wall parts, and arranging many needle shaped fins under the state the fins are extruded from the wall parts with intervals being provided. CONSTITUTION:A container 1 has a rectangular parallelopiped shape and has a bottom wall 2, an upper wall 3 and four sidewalls 4 at front, rear, right and left parts. In the inside of the container 1, a liquid phase region 5 is formed at the lower half part. The upper half part on the liquid phase region 5 is a vapor phase region 10, i.e., a space region filled with the vapor of boiled refrigerant. Many needle shaped fins 15 are provided along the entire outer surfaces of the upper wall 3 and the sidewalls 4 other than a panel 9. Therefore, the heat radiating area of the outer surface of the container is very wide. Since the fins have the needle shapes, air does not remain between the parts of the fins 15 on any wall surface. The fins 15 sufficiently perform the function as the heat radiating part. Thus the efficiency of the fins can be improved.
