Receiver/drier with integrated connection plate

摘要

A receiver/drier for fluid refrigerant having the housing formed of an aluminum header with a centrally disposed outlet port and off-center inlet port welded to an aluminum canister. A header sub-assembly is formed with an outlet tube with one attached to the header outlet port. A basket with a perforated bottom is filled with desiccant and the open end is attached to the header with the outlet tube ending through an aperture in the bottom of the basket. A layer of filter material is disposed adjacent the perforated bottom of the basket, the inner face of the header has plural concentric grooves interconnecting the inlet port and another layer of filter material disposed adjacent the grooved face of the header; and these grooves distribute flow over the filter in the event of contaminant accumulations in the inlet. The basket is attached to the header to complete the header sub-assembly prior to welding of the header to the aluminum canister.
