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.
Claims20
A scroll device comprising:
- a fixed scroll cooled by a first fluid circulation circuit;
- an orbiting scroll cooled by a second fluid circulation circuit, the orbiting scroll performing an eccentric movement relative to the fixed scroll;
- a motor cooled by a third fluid circulation circuit;
- and
- an internal cooling network comprising:
- a single axial circulation fluid supply channel, formed by an alignment of cylindrical segments through the first fluid circulation circuit and the second fluid circulation circuit, and incorporating an inlet port for connection to an external fluidic source, the inlet port leading directly into the single axial circulation fluid supply channel;
- and
- a single axial circulating fluid discharge channel, formed by the alignment of cylindrical segments though the first fluid circulation circuit and the second fluid circulation circuit, and incorporating an outlet port for connection to an external fluidic discharge, the outlet port leading directly into an outlet channel;
- wherein each of the single axial circulation fluid supply channel and the single axial circulating fluid discharge channel extend axially parallel to a longitudinal axis of the scroll device and passes by the fixed scroll and the orbiting scroll, and
- wherein the first fluid circulation circuit, the second fluid circulation circuit, and the third fluid circulation circuit are connected to the internal cooling network.
A scroll device, comprising:
- a parallel cooling line system comprising;
- an inlet configured to receive and convey a cooling fluid into the parallel cooling line system;
- an outlet configured to eject the cooling fluid exiting the parallel cooling line system;
- and
- a parallel cooling line operatively connected to the inlet and the outlet, wherein the parallel cooling line is configured to convey the cooling fluid from the inlet to the outlet via separate and discrete parallel cooling paths;
- wherein a first cooling path of the separate and discrete parallel cooling paths is arranged to convey a first portion of the cooling fluid along at least one component cooling area of the scroll device prior to reaching the outlet, wherein a second cooling path of the separate and discrete parallel cooling paths is arranged to convey a second portion of the cooling fluid along a different at least one component cooling area of the scroll device prior to reaching the outlet.
