ABSTRACT:
An aluminum header has spaced inlet and outlet ports formed thereon to closely interfit inlet and outlet tubes. A U-shaped standpipe has one end swaged in the outlet port and the opposite end spaced adjacent the header surface to control flow into the standpipe. A permeable dessicant filled pouch is folded over the standpipe and a deep drawn aluminum canister is received over the pouch and standpipe and welded to the header. An inlet tube with a convolution is received in the inlet port and header material deformed over the convolution to retain the tube. A separate outlet tube with a convolution adjacent one end is inserted in the outlet port from the side opposite the standpipe and header material deformed over the convolution to retain the tube in the outlet port. A bleed hole for lubricant is formed in the standpipe and a filter cartridge received over the standpipe and located over the bleed hole.
