Abstract

A scroll device includes a fixed scroll, and orbiting scroll, and a parallel path cooling circuit that receives coolant to cool the fixed scroll, the orbiting scroll, and a motor housing. The parallel path cooling circuit includes a cooling path that splits to enable cooling of two or more components in parallel to one another. The parallel path cooling circuit allows multiple components to be cooled with two discrete cooling paths that are arranged in parallel and lower a pressure drop of the coolant within the scroll device when compared to a cooling path that includes an in-series arrangement.

Abstract

A scroll device has a fixed scroll, and orbiting scroll, and at least one cooling chamber configured to receive coolant to cool the fixed scroll or the orbiting scroll. A flexible conduit that curves around an orbital axis of the orbiting scroll may transfer coolant into or out of the at least one cooling chamber. The scroll device may have a motor with a motor jacket configured to receive coolant for cooling the motor. One or more involutes of the scroll device may comprise a wall coated or plated with a solid abrasion-resistant lubricant.

Abstract

A compact energy cycle construction that operates as or in accordance with a Rankine, Organic Rankine, Heat Pump, or Combined Organic Rankine and Heat Pump Cycle, comprising a compact housing of a generally cylindrical form with some combination of a scroll type expander, pump, and compressor disposed therein to share a common shaft with a motor or generator and to form an integrated system, with the working fluid of the system circulating within the housing as a torus along the common shaft and toroidally within the housing as the system operates.
