Abstract: A removal device (1) is provided for the desiccant of the refrigerant of an air conditioner for vehicles, which is arranged in a receiver (4) connected to one manifold (2) of an integrated condenser/receiver unit (3) of the air conditioner and is fastened with one end (5) to a closure cover (6) of the receiver (4), the receiver (4) being connected via inflow and outflow openings (8, 9) in its wall (12) to the manifold (2). A receiving space for the desiccant is formed between the removal device (1) and the wall of the receiver (4) opposite the inflow and outflow openings. The removal device (1) has an impact wall (20) in the area of the inflow opening (8). The removal device (1) is formed as a rod (50) from the impact wall (20) to roughly the closure cover (6) designed as a plug (60) so that the wall of the receiver (4) lying on the side of the inflow and outflow openings is available as a boundary of the receiving space for the desiccant.

Abstract: A receiver for a vehicle air conditioner having a pair of headers and a plurality of tubes defining a plurality of refrigerant flow stages between the headers. The receiver includes a housing in refrigerant flow connection with one of the condenser headers, and a receiving device removably secured in the housing. The device includes first and second members sealing against the receiver to define respective spaced first and second walls, and at least one connection line is in or on the receiving device and bridges the spacing between the first and second walls, with the connection line being adapted to guide refrigerant through the spacing from one stage to another stage. Desiccant is provided in the housing between the first and second sealing members.

Abstract: An integrated condenser/receiver unit including a filter insert. The filter insert extends just beyond a refrigerant inlet of the receiver and is formed from a unitary plastic body having a flow-deflection portion and a filter portion. The flow-deflection portion is located opposite the refrigerant inlet of the receiver housing to prevent the refrigerant flow from the inlet from directly impinging a desiccant charge contained within the receiver housing. A method is provided for forming the condenser/receiver wherein a desiccant and filter are inserted into the receiver housing after the remainder of the condenser/receiver has been brazed together as a unit, and after insertion of the desiccant and filter, an end cap is metallurgically bonded to the receiver housing to close the same.

Abstract: An insert is provided for use in a refrigerant receiver of a vehicular air conditioning system. The receiver has an interior that receives the insert and a charge of desiccant. The receiver is connected to a header of a condenser by a refrigerant inlet to the interior from the header and a refrigerant outlet from the interior to the header. The insert includes a wall having a first and second oppositely facing sides. The first side lies closer to the inlet than the second side with the insert received in the interior of the receiver. A first portion of the wall is aligned with the inlet, and at least the first portion is substantially impervious to the refrigerant flow from the inlet to shield the desiccant charge from direct impingement by refrigerant flow from the inlet. In one embodiment, the second side cooperates with a surface of the interior to define a receptacle for the desiccant. In another embodiment, the second side defines a receptacle surrounding the desiccant.
