Abstract: An air deflection duct assembly is disclosed for use in adding an evaporative cooler unit to an existing refrigeration air conditioning duct to increase the efficiency of operation of the evaporative cooler by causing a higher percentage of the air flow from the cooler to pass into and through the existing refrigeration ducts. To accomplish this, first and second spaced apart duct assemblies are mounted over holes cut into the existing refrigeration air conditioning duct system. Each duct assembly has an adapter plate constructed with a circular hole in it, and this hole is normally closed by a pressure-opened deflector hinged at one edge of the hole. The hinged edges of the deflectors are mounted facing one another. When air is passed into the collar of the assembly extending upward from the hole from the evaporative cooler, the deflector plates open and extend at an angle into the existing refrigeration duct to deflect the air in opposite directions from the space between the openings cut in the duct.

Abstract: The present beverage cooling apparatus has an insulated container with an inclined bottom wall shaped to fit on top of a wheel well in the engine compartment of a car. A series of coiled pipes inside the container can be connected to the car's air conditioner to pass refrigerant through the interior of the container to cool the drinking water or other beverage. A thermostatic expansion valve cools the refrigerant just before it enters the container. This valve is regulated by a temperature sensor which senses the temperature of the refrigerant as it leaves the container. The container has a capped drain opening at the bottom at its deeper end, a capped fill opening at the top, and a freeze plug on one side which detaches itself from the container if the beverage freezes. A motor-pump unit on top of the container has a beverage intake pipe extending down near the bottom of the container at its deeper end, and a filter is provided on this end of the intake pipe.

Abstract: A spacecraft modular system with two components of a cooling system, one in each replacement hardware module and one in the satellite station, with a coupling means in the replacement module in the form of heat sink which collects heat from the heat generating hardware in the replacement module. The heat sink incorporates heat sink fins which interdigitize with coolant tubes in the satellite coolant system and make a mechanical interface with the fins in response to the satellite coolant system pressure for a thermally efficient heat exchange from the replacement module to the satellite coolant system. In another embodiment, replacement module coolant tubes interdigitize directly with the satellite coolant tubes in a fluid pressure responsive thermally efficient mechanical contact to provide a fluid-to-fluid mechanical coupling.
