Abstract: 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.

Abstract: The fluid inlet and outlet tubings (5,6) that project beyond a front surface (F1) of the radiator are inclined with respect to the longitudinal axes (A1, A2) of the fluid boxes (1, 2), so as to reduce the bulk of the radiator in the longitudinal direction of the fluid boxes (1, 2).

Abstract: A casing (1) is dedicated to housing a heat exchanger, in a heating, ventilation and/or air conditioning installation, for example of a motor vehicle. The heat exchanger comprises air inlet and air outlet faces, rear end and front end faces, and first and second side faces each capped with a radiator tank comprising a front end furnished with an orifice (6, 7) for connection to a heat transfer fluid supply circuit. The casing (1) comprises a front end wall (15) comprising an opening opposite the front end face (10) of the heat-exchanger, and a cover (24) i) comprising at least two passages (37, 38) adapted to suit the orifices (6, 7), ii) suitable to be placed against the front end face of the heat exchanger and to be fixedly attached to the front end wall (15), and iii) also comprising sealing means (39, 40) responsible for limiting the outlet of air via the opening and/or via at least one of the passages (37, 38).

Abstract: A casing (1) is dedicated to housing a heat exchanger (3) in a heating, ventilation and/or air conditioning installation, for example of a motor vehicle. The heat exchanger (3) comprises an air inlet face (12), an air outlet face (13), a rear end face (15), a front end face (14), and at least one side face (16, 17) capped with a radiator tank (4, 5). The casing (1) comprises side walls (18, 19) defining at least one housing to receive at least one part of the radiator tank (4, 5).
