CS267698B1 - Profiled heatexchange plates - Google Patents

Abstract

A heat exchanger comprises profiled heat exchanger plates which are assembled in such a manner that flow channels, the height of which is small compared with the width and length but substantially greater than the thickness of the plates, are formed between the plates. The curvature of curved pieces (3a, 4a, 3b, 4b) forming boundary walls of the channels changes steadily. These curved pieces have their greatest curvature in the regions in which they merge into each other or into an intervening straight portion, and their smallest curvature in the regions, in which they pass over into the curved pieces of profile curves of neighbouring profile elements. <IMAGE>
