Abstract: A condenser cooling device for an automobile air conditioner, and more particularly a water-operated auxiliary cooling means for accelerating the heat exchange rate of a coolant condensing device, mounted between a coolant reservoir and an expansion valve, and consisting of a housing, a heat exchanger, an air drawing means, a water reservoir, and a temperature-lowering tube. Cool water is pumped in a circular manner from the water reservoir to an elevated position above the heat exchanger and from which the cooled water is sprinkled through a tube having a plurality of water spraying bores down over the circular tube of the heat exchanger to assist the cooling of the air conditioner coolant.

Abstract: A condenser is formed from a plurality of pipes connected to a header with each pipe formed to define a lowermost straight portion on which a plurality of convoluted further straight portions are provided in the same vertical plane. Each straight portion is connected to the next by a curved connecting portion of a radius of curvature substantially equal to the spacing between each straight portion and the next straight portion so that the connecting portion extends to a height above the upper straight portion to which it is connected to. This ensures that each straight portion acts as a liquid trap to retain the condensate therein with the condensate and gas being bubbled over each connecting portion to move into the next liquid trap. The gas is injected at the lower header and the liquid extracted at the upper header. This tends to keep the inner surface of the pipe wetted with the condensate thus improving heat transfer and reducing the overall size of the condenser.

Abstract: A system for recovering and utilizing, to a controlled and variable extent, waste heat from a coolant fluid. The amount of heat recovery varies in proportion to the marginal costs associated therewith. Heat laden coolant passes through an interior heat exchanger where heat may be extracted in varying amounts from the coolant by a thermostatically-controlled air mover, the air mover admitting outside air past the interior heat exchanger. The coolant proceeds to an exterior wet surface heat exchanger where residual heat is concurrently extracted from the coolant by a thermostatically-controlled combination of ambient air, recirculated ambient air, and water spray. The coolant then returns to the beginning of its cycle. The temperature of outside air is the principal variable determining the proportion of heat recovered by the interior heat exchanger and the proportion extracted by the exterior heat exchanger. The total heat extracted reduces the coolant temperature to a predetermined operating level.
