ABSTRACT:
In a radiator having flat tubes arranged in parallel and connected to header pipes for feed and return flow, each flat tube has two connection bores near the front end thereof. To enable the radiator to be manufactured by the use of pressure welding, a support part, angled into U-form with two bent ends arranged coaxially with the two connection bores, is inserted into each flat tube. These ends of the support part prevent the flat tube from being pressed inwardly during pressure welding. The portion of the support part extending parallel with the end edge of the flat tube is welded to the tube end edge, so that the support part simultaneously also forms the end closure wall of the flat tube.
