The housing (14) comprises a body having at least one open face, with the body defining a frame around the open face. The body is formed by at least two parts (30; 32; 34; 36), which are assembled together by brazing, with at least two of the parts being provided adjacent to one another comprising means (40) for creating a support surface for a manifold (48). ## Claims ### Claim 1 A heat exchanger (10) comprising a heat exchange core (12) and a housing (14), inside which said heat exchange core (12) is housed, said housing (14) comprises: a body having at least one open face, said body defining a frame around said open face, and in that said body is formed by at least two parts (30; 32; 34; 36), which are assembled together by brazing, at least two of said parts being provided adjacent to one another comprising means (40) for creating a support surface for a manifold (48), said parts (30; 32; 34; 36) of said body each comprising a plate provided, on at least a part of its periphery, with said means (40) for creating a support surface, and wherein said means (40) for creating a support surface comprises raised manifold assembly edges (40), wherein said means for creating the support surface includes raised edges (40) extending approximately perpendicularly with respect to the general plane of extension of said plate forming one of said parts (30; 32; 34; 36), wherein at least one of said parts (30; 34) includes a perimeter bordered by first (44) and second (40) raised edges, and wherein an entire periphery of at least one of said parts (30; 34) is surrounded by a rib formed from said first (44) and second (40) raised edges. ### Claim 2 (depends on 1) The heat exchanger (10) as claimed in claim 1, wherein said housing (14) comprises four parts (30; 32; 34; 36). ### Claim 3 (depends on 1) The heat exchanger (10) as claimed in claim 1, wherein said means (40) is in contact with said means (40) of said adjacent part (30; 32; 34; 36) at one of its ends, so as to define said support surface over the entire periphery of the open face of said body of said housing (14). ### Claim 4 (depends on 2) The heat exchanger (10) as claimed in claim 2, wherein said raised edges (40) are connected by a brazed joint. ### Claim 5 (depends on 1) The heat exchanger (10) as claimed in claim 1, wherein said first raised edges (44) are involved in the assembling of said housing (14) and said second raised edges (40) are involved in the assembling of a manifold (48) on said housing (14). ### Claim 6 (depends on 1) The heat exchanger (10) as claimed in claim 1, wherein said body comprises two open faces located opposite one another. ### Claim 7 (depends on 1) The heat exchanger (10) as claimed in claim 1, wherein said housing (14) comprises two tubes (18; 20), provided at one of said parts (30; 32; 34; 36) of said housing (14), for the inlet and outlet, in said heat exchanger (10), of a heat transfer fluid. ### Claim 8 (depends on 7) The heat exchanger (10) as claimed in claim 7, wherein said heat exchange core (12) determines first channels for a gas to flow through and second channels for the heat transfer fluid to flow through. ### Claim 9 (depends on 1) The heat exchanger (10) as claimed in claim 1, wherein said heat exchange core (12) comprises a stack of plates (16). ### Claim 10 (depends on 1) The heat exchanger (10) as claimed in claim 1, wherein each of said parts (30; 32; 34; 36) of said housing (14) comprises an assembling means (42; 46) able to engage with said adjacent part so as to assemble said housing (14). ### Claim 11 (depends on 10) The heat exchanger (10) as claimed in claim 10, wherein said assembling means is a tab (42) and/or a recess (46). ### Claim 12 (depends on 2) The heat exchanger (10) as claimed in claim 2, wherein said raised edges (40) are in contact with said raised edges (40) of said adjacent part (30; 32; 34; 36) at one of its ends, so as to define said support surface over the entire periphery of the open face of said body of said housing (14). ### Claim 13 (depends on 12) The heat exchanger (10) as claimed in claim 12, wherein said raised edges (40) are connected by a brazed joint. ### Claim 14 (depends on 3) The heat exchanger (10) as claimed in claim 3, wherein said means (40) are connected by a brazed joint.
