ABSTRACT:
A fluid heat exchange apparatus is disclosed that can be used as an absorber in an absorption cooling system. The compact absorber design uses concentric thermally conductive cylinders to form alternating annular passages for a heat transfer fluid and a solution. The heat transfer fluid passages contain a generally helical coil. The generally helical coil distributes the heat transfer fluid in a generally helical path between the thermally conductive cylinders. The solution passages also contain a generally helical coil. However, the solution passage coils are grooved rods. The grooved rods allow solution to flow between the rods and the walls of the cylinders. The solution flows down the cool walls of the thermally conductive cylinders. Simultaneously, refrigerant vapor flows upward in a generally helical path within the solution passages and is absorbed into the solution droplets. Further, additional embodiments are disclosed that use a grooved rod to absorb a vapor into a solution.
