An air-cooled radiator core is described comprising a plurality of welded or soldered-together core elements. Each core element is fabricated of an elongated seamless loop of flat metal formed along its length with 90 degree out of phase sinuous side portions outwardly flanged along each edge, the sinuous side portions being in mutual abutment at out of phase node portions. Adjacent core elements are fitted flange-edge to flange-edge to define a honeycomb effect of core openings for the passage of cooling air; and abutting flanges are soldered or welded together along their outer edges to provide sinuous coolant flow paths between mutually adjacent core elements. In a modified form of the invention flat ribbons of sheet metal are folded back and forth along their lengths in a modulated pattern of such shape along their lengths as to fit snugly within and along the honeycomb openings to increase radiating surface areas and thereby improve the efficiency of air cooling action of a radiator core.
