<p>PURPOSE:To prevent helically coiled heat transfer pipes from being uneavenly fastened and supported by a method wherein a fixing metal and a heat transfer pipe receiving plate for supporting each of the heat transfer pipes are produced by press-molding a plate material having a thickness equal to that of the heat transfer pipe, so as to suit the radius of curvature of the heat transfer pipe. CONSTITUTION:A couple of helical heat transfer pipes 8 are held firmly between a press-molded heat transfer pipe receiving plate 19 and a press-molded fixing metal 15, respectively, by means of a fixing screw 16. The heat transfer pipe receiving plate 19 and the fixing metals 15 are press-molded by using a molding jig having a radius of curvature similar to that of each of the helical heat transfer pipes. Further, in order to reinforce the heat transfer pipe receiving plate 19, reinforcing plates 17 and a collar 18 are attached to a spacer 14. Such reinforcing plates 17 perform the functions of positioning the helically coiled heat transfer pipes and supporting an upper stage spacer of the like type.</p> |
