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.
Claims20
A scroll device comprising:
- a fixed scroll comprising a first involute and a first cooling chamber;
- an orbiting scroll comprising a second involute and a second cooling chamber, the orbiting scroll mounted to the fixed scroll via a mechanical coupling, the orbiting scroll configured to orbit relative to the fixed scroll around an orbital axis;
- and
- a flexible conduit in fluid communication with the first cooling chamber and the second cooling chamber, the flexible conduit extending around the orbital axis from a first side of the scroll device to a second side of the scroll device.
A scroll device comprising:
- an orbiting scroll mounted to a fixed scroll via at least one mechanical coupling, the orbiting scroll configured to orbit relative to the fixed scroll around an orbital axis, the fixed scroll comprising:
- a first involute extending toward the orbiting scroll;
- a first cooling chamber;
- and
- a first plurality of cooling fins extending away from the orbiting scroll into the first cooling chamber;
- a flexible conduit in fluid communication with the first cooling chamber, the flexible conduit having a first end connected to the fixed scroll, a second end connected to the orbiting scroll, and a length that bends around the orbital axis.
A liquid-cooled scroll device comprising:
- a fixed scroll comprising a first coolant passageway;
- an orbiting scroll comprising a second coolant passageway;
- a motor operably connected to the orbiting scroll, the motor causing the orbiting scroll to orbit relative to the fixed scroll around an orbital axis;
- and
- a flexible conduit that curves around the orbital axis, the flexible conduit in fluid communication with the first coolant passageway and the second coolant passageway.
