Abstract (en)

[origin: WO03048670A1] Heat exchanger 10 for providing supercritical cooling to the refrigerant of a transcritical cooling system 12 including a pair of elongated headers 20, 22 plurality of elongated tubes 28 spaced in side-by-side relation along the longitudinal axes 24, 26 of the headers 20, 22, and serpentine fins 30 extending between adjacent pairs of the tubes. Each of the tubes 28 is folded upon itself to define at least two parallel legs 36 of the tubes 28 and has a flattened cross-section. The parallel legs 36 of the tubes 28 are preferably spaced from each other, with the major dimension D of each of the parallel legs lying in a common plane. Each of the fins 30 includes alternating tabs 40 and elongated separations 42 extending parallel to the parallel legs 36 and located between the parallel legs 36 of the adjacent tubes 28 to divide the width W of each fin 30 into discrete fin elements 44 that are connected to each other by the tabs 40. Each of the fin elements 44 extends along one of the parallel legs 36 of the adjacent tubes 28.
