This invention relates to a heat exchanger having a core comprised of oblong shaped tubes having substantially flat longer sides and rounded shorter sides, the tubes being separated by and in contact with conventional wave-shaped external cooling fins. Locating plates are provided at both ends of the tubes to accurately align and to secure the tubes into position. The ends of the tubes are sealably secured to header plates by means of resilient grommets. The heat exchanger of the present invention provides better resistance to mechanical and thermal shocks than conventional heat exchangers having tubes soldered or brazed to the header plates and provides better cooling efficiency than heat exchangers having circular, grommetted tubes.
