HEAT EXCHANGER COMPRISING DEEP-DRAWN, INTEGRALLY FORMED DISTRIBUTION AND COLLECTING CHANNELS FOR HEAT-EXCHANGER MODULE PLATES COMPRISING A TEMPERING MEDIUM

摘要

The invention relates to a method for producing a heat-exchanger module for heat exchangers of electrochemical energy accumulators, wherein heat exchanger channels (43, 43', 44, 44') and flow manifolds (50, 50') and return collector tubes (60, 60') are incorporated into, respectively, two strips of material by deep-drawing, and flow manifolds and return collector tubes (55) are formed by turning over the ends of the material strips by 180°, said ends comprising the flow manifolds and the return collector tubes. Subsequently, a heat exchanger module (40) is obtained by aligning and combining the material strips provided with the flow manifolds and the return collector tubes (66).
