Filed:

Sep 10, 1992

Appl. No.:

7/942896

Inventors:

John G. Ingersoll - Topanga CA
Linda M. Maxwell - Redondo Beach CA

Assignee:

Hughes Aircraft Company - Los Angeles CA

International Classification:

F23L 1502
F25D 1706

US Classification:

62 78

Abstract:

A desiccant air conditioning system (10) is provided for a passenger compartment (28) of a vehicle. Ambient air, to be eventually conditioned, passes through desiccant material maintained in a desiccant chamber (14) where it loses a portion of its moisture content while its temperature rises because of the release of the heat of vapor condensation. Subsequently, this hot, dry air is passed through a heat exchanger (20) where it is cooled down to a temperature close to the ambient. This very dry, cool air is then humidified by a humidifier (24), becoming cool, moist air, that is introduced into the passenger compartment of the vehicle. Exhaust air (30) from the passenger compartment is further humidified by a humidifier (32), so as to cool it. This cooled, humidified air is then passed through the heat exchanger (20) to cool the hot, dry incoming air. The air conditioning system may also be used in a heating mode by simply deactivating the heat exchanger (20) and the two humidifiers (24 and 32) and using the exhaust air from the passenger compartment as the source of the air (42) incoming into the desiccant chamber.

Abstract:

A retainer (10) mechanically and thermally couples an electronic cardboard (12) to a heatsink (14) between first and second continuous surfaces (30, 38) of walls (26, 28) on a base (22). Clamping is effected by moving a pair of wedges (54) and (56) and their slanted surfaces (58, 60) against corresponding slated surfaces (42, 44) of a clamping block (36). The clamping block has an oblique surface (40) which cooperates with a surface (32) on wall (28) to move the block and its surface (38) toward surface (30), thus clamping the card at both surfaces in tight mechanical and thermal contact.
