Abstract

A condenser (10) with a return header tank (14) has a receiver or reservoir canister (22) physically attached along side the return header tank (14), and open thereto through a discrete upper inlet (20) and lower outlet (21). The bottom of canister (22) is closed by an end cap (34) that is, preferably, welded or brazed in place. Before end cap (34) is attached, a tube of desiccant material (24) is installed and located within canister (22) by a standoff (26) comprised of a tight fitting, notched, disk shaped base (28) and narrow central post (30) which is comparable in length to the height of the inlet (20) above the lower end cap (34). The tight fit allows the tube (24) to be inserted up into the canister (22), well away from the bottom of canister (22) and free of heat damage as the end cap (34) is attached. Later, in operation, the central post (30) keeps the tube (24) located clear of the inlet (20) and outlet (21).
