Abstract

PURPOSE: To improve the welding property of a frame and a radiating rib and the efficiency of work, by providing peripheral length adjusting grooves on the radiating rib provided with numerous radiating fins on a steel band.
CONSTITUTION: A thin steel sheet is bent as waves so that a radiating rib 7 is provided with numerous continuous radiating fins 7a. When the rib 7 is shaped as a hollow rectangular parallele-piped, adjusting grooves 5 are provided on the shaped rib to adjust its peripheral length. The major edge length A1 and minor edge length B1 of an upper frame plate 6 and a bottom plate 8 are set slightly smaller than the inside major edge length A and inside minor edge length B of the radiating rib 7. Pressure is applied to both the ends of the adjusting grooves 5 as the frame plate 6 and the bottom plate 8 are fitted in the radiating rib 7. As a result, the top and bottom of the rib are tightly fitted on the sides of the frame plate 6 and the bottom plate 8. The conjoined edge parts of the frame plate 6 and the bottom plate 8 are welded on those of the radiating rib 7 along its total periphery.
