Abstract:
1. A device separating a working fluid from a cooling fluid within a housing having a fixed scroll enmeshed with an orbiting scroll, said orbiting scroll driven by an eccentric shaft, a motor driving said device, and a housing containing said fixed scroll and said orbiting scroll, the device further comprising: said orbiting scroll having a front surface and an opposite back surface, said front surface having a plurality of spiral fins thereon engaging said fixed scroll and said back surface having a plurality of fins thereon; an orbiting cooling plate on the back surface of the orbiting scroll, the orbiting cooling plate having a groove forming a passage for circulation of a liquid coolant to remove any built up heat; a fixed cooling plate on the fixed scroll, the fixed cooling plate having a groove forming a passage for circulation of a liquid coolant to remove any built up heat; said housing having a plurality of fins therein, said fins of said housing fitting within said fins upon said back surface of said orbiting scroll wherein heat transfers from said orbiting scroll to said housing and wherein said housing is air cooled; said device including an enclosed plenum, said plenum extending from the center of said orbiting scroll axially outwardly of said device, said plenum preventing infiltration of working fluid with heated fluid inside said housing; a magnetic connection between said motor and said device, said magnetic connection transmitting rotation of said torque from said motor to said device therein driving said eccentric shaft causing said orbiting scroll to orbit; said housing having an interior surface towards said motor, said interior surface having said plurality of fins locating thereon; said plurality of fins upon said orbiting scroll are one of flat, spiral, and cylindrical; said plurality of fins upon said interior surface of said housing are one of flat, spiral, and cylindrical cooperating with said plurality of fins upon said orbiting scroll in removing heat from said device to the atmosphere; said plurality of fins upon the front and back surfaces of said orbiting scroll being spiral shaped, and said plurality of fins upon said interior of said housing being spiral shaped in cooperation with said plurality of fins upon said orbiting scroll wherein said plurality of fins inherently pump the working fluid within the housing to increase heat transfer from said device; said magnetic connection between said motor and said device being one of a magnetic coupling and magnetic face seal; said motor having a shaft extending outwardly from said motor and said device having a shaft in connection to said orbiting scroll and extending outwardly from said device; said magnetic connection between said motor and said device being a magnetic coupling; and said magnetic coupling including a shroud, being hollow and connecting said motor to said device, an outer rotor having magnetic polarity, a stationary can within said outer rotor connecting to said housing, said stationary can lacking a magnetic polarity, and an inner rotor within said stationary can connecting to said shaft of said device, said inner rotor having a magnetic polarity opposite that of said outer rotor.
