Optionally the tube ends may be chilled for contracting or reducing their diameters just prior to assembly and then after being press iitted in the headers and brought back to room temperature their growth will insure a leakprool' joint. For thoroughly satisfactory 1. The method of manufacturing radiators or the like, including forming a tubular shell with a central bulge and reduced end portions, forming a tube bundle core with molded hard plastic headers at opposite ends and of slightly greater shell end portions to which the diameter than the headers are to be tted, inductively heating said reduced end portions to temporarily enlarge the same suiiiciently to receive the larger diameter headers and axially moving the tube bundle and header assembly into the shell while said end portions are temporarily enlarged for subsequent contraction of both end portions into shrink lt with both headers.
2. The methodI of assembling heat exchangers or-the like comprising forming the core with spaced headers and forming the whousing with correspondingly spaced header engaging bands of slightly smaller internal diameter than the external diameter of the headers, applying heat to one of the bands to temporarily enlarge the same, passing one of the headers through the enlarged band to bring both headers into proximity to the bands, respectively, then applying heat to both bands to enlarge them, adjusting the core and housiig to place both headers inside the enlarged bands respectively and thereafter discontinuing the application of heat toenable the bands to shrink on the headers.. a
