The invention relates to a heat exchanger including exchange components and fluid flow components (), at least one fluid collecting tank (') into which the exchange components open out (), and a housing () for accommodating the exchange components (). The exchanger is characterized in that it includes a flange () for fixing the collecting tank (&#x2032;) on the housing (), the flange comprising a groove (G) for fixing the housing () and a groove (G) for fixing the collecting tank (), the grooves (G, G) having a common wall (). Thanks to the invention, a very compact heat exchanger is obtained.

Heat exchanger

The invention relates to a collector plate () for a heat exchanger comprising a web () equipped with openings for the passage of tubes of the heat exchanger and a groove (), known as a receiving groove, to accept a header tank cover, able to accept a gasket () and part of the cover and having a base () and two flanges, respectively an inner flange () and an outer flange () which are connected to the base (). The inner flange () is connected to the web () and is subdivided into at least two disjointed portions, the two disjointed portions are separated by at least one recess (), and the recess () between the two disjointed portions of the inner flange () is at least in the region of a site of the collector plate () that is intended to accept a bent part of the gasket (). The invention also relates to a heat exchanger comprising the collector plate ().
