A RADIATOR

摘要

A fluid-filled radiator is manufactured from a plurality of relatively shallow tubular panel elements (61 to 64) by arranging the panel elements edge to edge and inserting at least one reinforcing member (20) into each end of each panel element, the reinforcing members fitting closely between the opposite major surfaces of the panel elements. A plurality of individual bridging members (90) are resistance welded to each end of each adjacent pair of panel elements, each bridging member extending from a major surface of one panel element to a major surface of the adjacent panel element. The reinforcing members (90) prevent the collapse of the panel elements under the pressure of the resistance welding.
