Abstract

The embodiment of the invention disclosed herein is directed to a rotary compressor and/or condenser for refrigerating systems. The rotary compressor has a rotor with a passage formed therethrough to be in fluid communication with an inlet port at one end of the rotor housing and in periodic fluid communication with an outlet formed at the other end of the rotor housing. The outlet passage is formed in a valve plate which is in sliding sealing contact with the terminating end of the rotor of the compressor. A condenser may be connected to a common shaft with the compressor rotor and has a rotating member with a helical passage extending therethrough. Heat radiating fins are formed on the condenser rotor to improve heat transfer for cooling.

Claims

1. A heat exchanger comprising in combination:

a helically wound tubing, an inlet formed at one end of said tubing, an outlet formed at the other end of said tubing, a plurality of heat radiating fins secured to the tubing and arranged along a longitudinal axis of rotation of the helically wound tubing, drive means coupled to said helically wound tubing for rotating said tubing about said longitudinal axis of rotation, whereby heated fluid passing through said helically wound tubing will be cooled during rotation thereof.

2. The heat exchanger according to claim 1 wherein said fins are located radially inwardly of said helically wound tubing.

3. The heat exchanger according to claim 1 wherein said fins are located radially outwardly of said helically wound tubing.

4. The heat exchanger according to claim 1 further including a length of tubing connected between said inlet and said outlet and passing through the helically wound tubing.

5. The heat exchanger according to claim 4 wherein said length of tubing passes through said helically wound tubing along the longitudinal axis of rotation thereof.
