Abstract
This gas equipment, for other than air, includes a fixed scroll and an orbiting scroll, each having fins upon their back surfaces. The orbiting scroll remains within a housing having fins that engage with the fins on the orbiting scroll. The internal fins of the housing transfer heat from the orbiting scroll to the housing for air cooling by the atmosphere. The spiral arranged fins pump working fluid within the housing to increase heat transfer. The housing may also have an exterior fan. The orbiting scroll receives torque and rotation from a magnetic coupling or magnetic face seal, without a physical connection to a motor, so that the atmosphere does not infiltrate inside the housing. The present invention also has an enclosed inlet plenum to prevent infiltration of the atmosphere into the working fluid.
