Abstract
A heat exchanger () comprises an alternating stacking of first plates () and second plates () provided respectively with first corrugations () separated by a first pitch (P) and second corrugations () separated by a second pitch (P), which is different from the first pitch (P). Between the plates, first flow channels are defined having a first cross sectional area adapted to a first fluid (F) which alternate with second flow channels having a second cross sectional area adapted to a second fluid (F). The invention applies in particular to heat exchangers for motor vehicles.
