Heat exchanger and manufacturing process for such an exchanger

Abstract

Heat exchanger and method for manufacturing such an exchanger. The invention relates to a heat exchanger (1) configured to allow the exchange of heat between a first fluid and a second fluid, comprising: - a stack of ribbed plates (10) along a stacking direction (E), forming channels (12) configured to form a first fluid circuit in which the first fluid flows and a second fluid circuit in which the second fluid flows, - a collection box comprising at least one fluid inlet and outlet fluidly connected to the circuit of the first fluid, the plate positioned at a first end of the stack of ribbed plates (10) along the stacking direction (E) being a fixing plate (11) configured to be fixed to said collection box, the plates of the stack of ribbed plates being made of metal, the collection box being made of a material other than metal.preferably a polymer material.
