Abstract: In accordance with one preferred embodiment, a desiccant cartridge (30) for insertion into an integrated condenser/receiver (10) comprises a rigid stand-off member (72) and a porous desiccant bag (34). The preferred rigid stand-off member comprises spaced inner and outer pad portions and an elongated stand-off portion terminating in the inner pad portion. The inner pad may include a tab portion. The porous desiccant bag is positioned between the inner and outer pad portions and affixed to one or both of the inner and outer pad portions. A rigid cap with a plurality of holes may be provided to which a second end of the porous desiccant bag may be attached. The porous desiccant bag includes first and second flat end seals, one of which is secured to attachment tab portions.

Abstract: A desiccant package for insertion into an integrated condenser dryer chamber of an air conditioning unit. The desiccant package includes an internal cage component which is enclosed inside a porous desiccant-containing bag. The internal cage component comprises an enlarged diameter base unit and sealing section to seal and support the desiccant package inside the dryer chamber. The desiccant package can be inserted into the condenser dryer at initial assembly of the air conditioning unit or as a replacement item when the original desiccant is fully saturated.

Abstract: Method of preparing an adsorbent containing package and package made thereby. The method comprises providing a mounting surface of the package and heat fusing the mounting surface via ultrasonic welding to provide a multiplicity of depressed hard seal portions and relief surfaces on the mounting surface. The ratio of hard sealed portions to total seal area is within 10-60%.

Abstract: This invention relates generally to desiccant cartridges for use in R/Ds or accumulators canisters of automotive air conditioning systems. More specifically, this invention relates to a desiccant cartridge including a cup having inner and outer walls coaxially disposed wherein the inner wall defines an elongated center tube having opposing first and second ends. The first end of the center tube communicating with the outlet port in an R/D or accumulator canister to eliminate the fluid flow tube used therein.

Abstract: A desiccant containing cartridge (10) has a cap (12) and a generally cylindrically cross-sectioned cup (14) for holding desiccant particles (16) and a dye wafer (18). The cup (14) includes spaced inner and outer wall portions (20, 24) connected by a transverse portion (28) to define a chamber (30) having an opening (32) for the placement of a dye wafer (18) and desiccant particles (16). The cap (12) has a planar portion (52) having outer circumference (53) and inner circumference (54) defining aperture (55) for receiving inner wall portion (20) of the cup (14) and being designed for receipt in chamber (30) to cover opening (32).

Abstract: A desiccant cartridge retention device used to secure desiccant cartridges (10) to fluid flow tubes (12) and/or canisters (14) of receiver/dryer and accumulator assemblies (78). Desiccant cartridge (10) includes a cup (16) extending along an axis (20) and having spaced inner and outer wall portions (18, 22) connected by a transverse portion (24) to define a chamber (26) having an opening (28) for receiving desiccant particles (30). The inner wall portion (18) defines a sleeve (36) having first and second openings (37, 38) and further comprises an outer surface (40) and an inner engagement surface (42). The sleeve (36) is adapted to receive and the inner engagement surface (42) is adapted to cooperate with fluid flow tube (12) such that the desiccant cartridge (10) is secured thereto forming a proper seal therebetween. Outer wall portion (22) includes a flange adapted to provide a snug compression fit within canister (14) such that the desiccant container (10) also is secured thereto.

Abstract: An adsorbent package is provided for use within the sealed canister of a fluid flow tube of an air conditioning system. The adsorbent package includes a desiccant bag formed of a pouch having a sealed first end and a substantially cylindrical second end. A filter cap is slidably and sealingly received within the second end of the pouch. The cap includes a resilient sealing ring formed proximate a porous end wall. The sealing ring slidably and sealingly engages an inner surface of the canister. The package is constructed of a non-woven spun bonded nylon and can therefore be snugly received within the tight confines of fluid flow tube or canister sections of an integrated condenser receiver.
