ABSTRACT:
A method of manufacturing a desiccant assembly for a refrigeration circuit of the type used in automotive air conditioning systems. The method includes performing a container body by cutting a piece of seamless tube stock and friction forming one end of the tube to form an end wall. One or more apertures are formed within the container body to accommodate refrigerant circuit fittings. A refrigerant tube is installed in the container body along with associated components such as the desiccant material, additional fittings etc. Thereafter, the container body is again friction formed to enclose the opposite end wall of the container. The method according to this invention avoids the disadvantages associated with a multi-piece desiccant container which is subject to refrigerant leakage.
