Insert for use in a refrigerant receiver

摘要

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.
