Three-dimensional printing process, swirling device and thermal management process

摘要

A three-dimensional printing process, a swirling device, and a thermal management process are disclosed. The three-dimensional printing process includes distributing a material to a selected region, selectively laser melting the material, and forming a swirling device from the material. The swirling device is printed by selective laser melting. The thermal management process includes providing an article having a swirling device printed by selective laser melting, and cooling a portion of the article by transporting air through the swirling device.

主权项

1. A process for forming a thermally managed turbine component, comprising:
forming a turbine component, the component being selected from the group consisting of a turbine shroud, a turbine bucket, and a turbine nozzle; and forming a plurality of vortex tubes in a substantially parallel arrangement in the turbine component by a three-dimensional printing process, the three dimensional printing process including distributing a material to a selected region and selectively laser melting the material, wherein the plurality of vortex tubes are arranged and disposed to tangentially accept a pressurized fluid into chambers of the plurality of vortex tubes having circular or substantially circular profiles, and divide the pressurized fluid into first fluid streams and second fluid streams, the first fluid streams having elevated temperatures relative to the second fluid streams.
