Abstract
A scroll device has a fixed scroll, and orbiting scroll, and at least an integrated cooling loop configured to receive coolant to cool the fixed scroll and the orbiting scroll. A flexible conduit is provided that curves radially around an orbital axis of the orbiting scroll to transfer coolant along integrated cooling loop. The integrated cooling loop separates coolant used to cool the fixed scroll and the orbiting scroll from the involutes of the scroll device providing clean operation of the scroll device. The integrated cooling loop may be defined by the flexible conduit, one or more cooling chambers, and/or one or more cooling passageways.
Claims20
A scroll device comprising:
- a cooling fluid reservoir;
- a fixed scroll comprising a first involute;
- an orbiting scroll comprising an orbital axis and a body having a thickness defined by a distance measured in an axial direction running parallel to the orbital axis between a first surface of the body and a second surface of the body, a second involute extending from the first surface in the axial direction away from the second surface of the body, and a set of cross holes extending through the body transverse to the orbital axis and between the first surface and the second surface from a first side of the body offset a first transverse distance from the orbital axis to a second side of the body, the orbiting scroll mounted to the fixed scroll via a mechanical coupling, the orbiting scroll configured to orbit relative to the fixed scroll around the orbital axis;
- and
- an integrated cooling loop comprising a cooling fluid flow path running from the cooling fluid reservoir to the set of cross holes and back to the cooling fluid reservoir, wherein cooling fluid routes along the cooling fluid flow path.

A scroll device comprising:
- a fixed scroll comprising a first involute and a cooling fluid reservoir disposed on a side of the fixed scroll opposite the first involute;
- an orbiting scroll comprising a second involute and a set of cross holes extending from a first end to a second end, 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;
- an integrated cooling loop comprising a cooling fluid flow path running from the cooling fluid reservoir to the set of cross holes and back to the cooling fluid reservoir, wherein cooling fluid routes along the cooling fluid flow path;
- and
- a heatsink attached to the fixed scroll and comprising a set of cooling fluid fins disposed on a first side of the heatsink and a set of air fins disposed on a second side of the heatsink opposite the first side of the heatsink, wherein the set of cooling fluid fins extend into the cooling fluid reservoir and in contact with the cooling fluid routing along the cooling fluid flow path, wherein the cooling fluid reservoir is sealed by the first side of the heatsink preventing cooling fluid from reaching the set of air fins, and wherein a heat conduction path runs from the set of cooling fluid fins disposed in the cooling fluid reservoir through the heatsink to the set of air fins disposed external to the cooling fluid reservoir.
