Patent number: 9395126Abstract: Superalloy components, such as steam and gas turbine blades or vanes, are cooled during welding fabrication or repair, so as to reduce likelihood of weld metal and weld heat affected zone cracking during weld solidification and during post weld heat treatment. More particularly the invention relates to cooling superalloy steam and gas turbine components, such as turbine blades or vanes during weld repair. A heat sink apparatus includes a heat sink having a first surface adapted for abutting orientation with a turbine component second surface; and a non-gaseous, conformable, heat conductive material adapted for conforming contact with both surfaces. The heat conductive material fills gaps between the heat sink and turbine component abutting surfaces, and facilitates enhanced conductive heat transfer, in order to minimize negative heat effects from welding. The apparatus may be incorporated in a cooling system that varies heat sink cooling capacity in response to sensed component temperature.Type: GrantFiled: March 13, 2013Date of Patent: July 19, 2016Assignee: Siemens Energy, Inc.Inventors: Gerald J.

Patent number: 9332677Abstract: In an electronic device, a substrate mounting unit is provided at a front side inside a housing, and contains a plurality of electronic substrates under a state where faces of any two mutually adjacent ones of the plurality of electronic substrates are opposite to each other. A power supply unit is provided at a position which is located at a rear side inside the housing and is located behind the substrate mounting unit, and supplies the plurality of electronic substrates with electric power. A power-supply fan unit, which is provided at a rear side of the power supply unit, takes in air outside the housing from the power-supply air intake opening, and discharges the taken-in air to an outside of a rear side of the housing via the substrate mounting unit and the power supply unit.Type: GrantFiled: April 13, 2012Date of Patent: May 3, 2016Assignee: NEC CORPORATIONInventor: Norihiko Nishio

Patent number: 9228773Abstract: An automated control device for monitoring the position angle of an absorption type cooling system or refrigerator that circulates a refrigerant, an absorbent, and a diffusion agent within a conduit system includes a housing, a controller with a processor within the housing, a sensor in communication with the controller for measuring the angle of inclination of the refrigerator, and a stress counter connected to the controller for counting increments of stress induced into the cooling system. The tilt monitoring control method prevents system stress, which in turn prevents personal and property damage due to hydrogen gas leaks, fires and explosions.Type: GrantFiled: March 8, 2012Date of Patent: January 5, 2016Assignee: DOMETIC SWEDEN ABInventors: David William Leistner, Robert C.

Publication number: 20150136372Abstract: A fluid cooled cold plate can comprise a fluid output port connected near a thermally conductive base plate having a coupled heat source device, a fluid input port connected to a top surface of the cold plate, and multiple extended surface areas connected to the base plate and extending normal to the base plate. The cold plate can be configured for generally uniform fluid flow across the multiple extended surface areas. Furthermore, the multiple extended surface areas can create more resistance near a top surface of the multiple extended surface areas and less resistance near the base plate. For example, the plurality of extended surface areas can be wires that are wound near the base plate and fanned out near the top surface. An advantage of the disclosed cold plate design is the increase in heat transfer area and efficiency.Type: ApplicationFiled: December 19, 2014Publication date: May 21, 2015Applicant: Arizona Board of Regents on behalf of Arizona State UniversityInventor: Jonathan A.
