Abstract
A heat exchanger or condenser for a refrigerant system having an inlet tubular heat exchange surface and an enlarged tubular outlet. A cartridge type filter/drier has a shell or canister containing desiccant secured to a header with an outlet. In one embodiment the header is welded in the condenser enlarged outlet; and, in another embodiment the header is sealed in the enlarged outlet by an o-ring and retained by deforming the outlet tube over the header.
Claims12
An exothermic heat exchanger for a refrigeration system comprising:
- (a) a plurality of conduits disposed in spaced generally parallel arrangement;
- (b) a first and second manifold, each disposed for interconnecting common ends of said conduits for permitting flow therebetween;
- (c) a tubular outlet formed in one of said first and second manifolds;
- (d) one of said first and second manifolds defining integrally therewith a cartridge receiving cavity therein;
- and,
- (e) a cartridge assembly received in said outlet, said cartridge assembly having:
- (i) a header with an outlet port adapted for external conduit connection and a basket having the rim thereof attached to said header with the remote end thereof perforated;
- (ii) desiccant material disposed within said basket;
- (iii) sealing means operative to seal said header in said outlet.
A condenser for pressurized refrigerant flow therethrough comprising:
- (a) a tubular manifold having an inlet and an enlarged end portion comprising an outlet;
- (b) a plurality of tubes disposed in spaced generally parallel arrangement and each having one end communicating with said manifold;
- (c) a cartridge received in said enlarged end portion;
- said cartridge received in said cavity and having:
- (i) a header with an outlet port adapted for external conduit connection thereto;
- (ii) a basket having the rim of the open end thereof attached to said header with the end remote therefrom perforated;
- (iii) desiccant material disposed within said basket;
- (iv) a perforated member disposed between said desiccant and defining a plenum chamber communicating with said header outlet port;
- and,
- (d) a means operative to retain and seal said header in said enlarged end portion of said manifold.
A condenser for flow of pressurized refrigerant therethrough comprising:
- (a) tubular manifold means having an inlet end and communicating with a plurality of conduits defining heat exchange surfaces and said manifold means having an enlarged end portion defining an outlet;
- (b) a cartridge received in said outlet, said cartridge having:
- (i) a receptacle shell containing desiccant material and having a perforated inlet portion;
- (ii) a header attached to said shell and defining an outlet;
- (iii) means sealing said header in said enlarged end portion of said conduit means.
