PLATE-TYPE HEAT EXCHANGER, PARTICULARLY FOR MOTOR VEHICLES

摘要

A heat exchanger (10) comprises an alternating stack of first plates (12) and of second plates (14) respectively provided with first corrugations (16) separated from one another by a first spacing (P1) and of second corrugations (18) separated from one another by a second spacing (P2) which is different from the first spacing (P1). This thus defines, between the plates, first circulation passages with a first passage cross section suited to a first fluid (F1) which alternate with second circulation passages which have a second passage cross section suited to a second fluid (F2). The invention applies particularly to heat exchangers for motor vehicles.
