A casing houses a heat exchanger in a vehicle HVAC system. The heat exchanger includes air inlet and air outlet faces, rear end and front end faces, and first and second side faces. The side faces are each capped with a radiator tank comprising a front end. Each radiator tank defines an orifice for connection to a heat transfer fluid supply circuit. The casing includes a front end wall defining an opening opposite the front end face of the heat-exchanger. The casing also includes a cover defining at least two passages adapted to suit the orifices of the radiator tanks and fixedly attached to the front end wall. The cover also includes seals for limiting the outlet of air via the opening and/or the passages.

The invention claimed is: 1. An HVAC assembly comprising: a heat exchanger (3) comprising an air inlet face (8), an air outlet face (9), a rear end face (11), a front end face (10), and first (12) and second (13) side faces; a radiator tank (4, 5) comprising a front end and defining orifices (6, 7
The invention claimed is: 1. An HVAC assembly comprising: a heat exchanger (3) comprising an air inlet face (8), an air outlet face (9), a rear end face (11), a front end face (10), and first (12) and second (13) side faces; a radiator tank (4, 5) comprising a front end and defining orifices (6, 7) for connection to a heat transfer fluid supply circuit; and a casing (1) for housing said heat exchanger, said casing (1) comprising a front end wall (15) defining an opening (14) opposite said front end face (10) of said heat exchanger (3), and a cover (24) defining at least two passages (37, 38) adapted to suit said orifices (6, 7), said cover placed against the front end face (10) of said heat exchanger (3) and fixedly attached to said front end wall (15), said cover comprising sealing means (39, 40, 36, 41) for limiting the outlet of air via said opening (14) and/or via at least one of said at least two passages (37, 38), and said cover (24) comprises a shell (42) made of a first material, and wherein said sealing means (39, 40, 36, 41) are overmolded on said shell (42) and made of a second material having a greater elasticity and compressibility than those of the first material. 2. The assembly according to claim 1, characterized in that at least one part of said sealing means (39, 40) is arranged to espouse the contour of at least one part of each passage (37, 38), and in that said sealing means (39, 40) are made of an elastic material. 3. The assembly according to claim 2, characterized in that a linking part protrudes from said cover into a second (38) of said passages for engaging said front end face (10) of said heat exchanger (3), and in that said at least one part of said sealing means (39, 40) defines at least one band (40) surrounding at least a portion of said linking part of said second passage (38). 4. The assembly according to claim 2, characterized in that said cover comprises a linking part protruding into each passage (37, 37) for engaging said front end face (10) of said heat exchanger (3), and in that said part of the sealing means defines at least two bands (40) each surrounding at least a portion of each of said linking parts of said passages (37, 38). 5. The assembly according to claim 2, characterized in that said cover (24) comprises a peripheral edge (35) furnished with a peripheral sealing band (36) forming at least one part of said sealing means. 6. The assembly according to claim 2, characterized in that said sealing means comprise at least one auxiliary band (41). 7. The assembly according to claim 2, characterized in that a first (37) of said passages leads entirely to said front end face (10) of said heat exchanger (3), and in that said at least one part of said sealing means (39, 40) defines a first collar (39) surrounding said first passage (37) and one of said orifices (6). 8. The assembly according to claim 7, characterized in that a second (38) of said passages leads entirely to said front end face (10) of said heat exchanger (3), and in that said at least one part of said sealing means (39, 40) defines a second collar surrounding said second passage (38) and another of said orifices (7). 9. The assembly according to claim 7, characterized in that a linking part protrudes from said cover into a second (38) of said passages for engaging said front end face (10) of said heat exchanger (3), and in that said at least one part of said sealing means (39, 40) defines at least one band (40) surrounding at least a portion of said linking part of said second passage (38). 10. The assembly according to claim 1, characterized in that said cover (24) comprises a peripheral edge (35) furnished with a peripheral sealing band (36) forming at least one part of said sealing means. 11. The assembly according to claim 1, characterized in that said sealing means comprise at least one auxiliary band (41). 12. The assembly according to claim 1, characterized in that said cover (24) comprises attachment means (33) for allowing the fixed attachment of a fitted element. 13. The assembly according to claim 12, characterized in that said casing defines a second opening (34) for accommodating a front end face of an auxiliary heat radiator and wherein a positive temperature coefficient resistor (PTC resistor) forms said fitted element. 14. An HVAC assembly comprising: a heat exchanger (3) comprising an air inlet face (8), an air outlet face (9), a rear end face (11), a front end face (10), and first (12) and second (13) side faces; a radiator tank (4, 5) comprising a front end and defining orifices (6, 7) for connection to a heat transfer fluid supply circuit; and a casing (1) for housing said heat exchanger, said casing (1) comprising a front end wall (15) defining a first opening (14) opposite said front end face (10) of said heat exchanger (3), and a cover (24) defining at least two passages (37, 38) adapted to suit said orifices (6, 7), wherein said cover placed against the front end face (10) of said heat exchanger (3) and fixedly attached to said front end wall (15), said cover comprising sealing means (39, 40, 36, 41) for limiting the outlet of air via said opening (14) and/or via at least one of said at least two passages (37, 38), and said cover (24) comprising attachment means (33) for allowing the fixed attachment of a fitted element; and wherein said casing defines a second opening (34) for accommodating a front end face of an auxiliary heat radiator and wherein a positive temperature coefficient resistor (PTC resistor) forms said fitted element. 15. The assembly according to claim 14, characterized in that said cover (24) comprises a shell (42) made of a first material, and in that said sealing means (39, 40, 36, 41) are overmolded on said shell (42) and made of a second material having a greater elasticity and compressibility than those of the first material.
