A radiator tube ( 111 ) having a portion at each end which is adapted to be received in a header tank of a radiator and an intermediate portion between the ends, said intermediate portion having a cross section defined by a pair of side walls ( 121 ) and a pair of end walls ( 123 ), the side walls are generally parallel and have a spacing between them which is less than the spacing between the end walls, the side walls supporting a set of generally parallel fins ( 113 ), each fin extending laterally from the tube, each fin having an inner side edge thermally communicating with the respective side wall of the tube and an outer side edge ( 119 ) in a substantially spaced parallel relationship with the inner side edge, a forward edge ( 115 ) and a rear edge ( 117 ), said forward edge having an arcuate configuration taking the form of a continuous curve extending from the forward most edge of the fin to the outer side edge. |
