Limiting elements are mounted on the stator device axially on both sides to thereby bound an internal rotor space which is in communication with axial ends of the first cooling channels of the stator device to thereby establish an internal air-cooling circuit from the internal rotor space through the first cooling channels and back into the internal rotor space.Type: GrantFiled: March 27, 2013Date of Patent: March 8, 2016Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Klaus Büttner, Klaus Kirchner, Michael Müller

Publication number: 20150060019Abstract: A pulsating multi-pipe heat pipe having its metal pipes arranged in-parallel and bent in snake-shaped loop, is capable of making the working fluid flow through the pulsating multi-pipe heat pipe, enhance the pressure difference therein so as to improve its heat-dissipating effect and successfully overcome the problems of horizontal action when the heat pipe is laid in horizontal position. This is done by attaching at least a chambered connector in the metal pipes having their cross-sectional areas greater than the total cross-sectional areas of the metal pipes or furnishing at least a pair of communicative penetrating holes at the side-by-side adjacent pipe walls making the working fluid create cross-flow within the pulsating multi-pipe heat pipe.Type: ApplicationFiled: November 19, 2013Publication date: March 5, 2015Applicant: Industrial Technology Research InstituteInventor: CHIH-YUNG TSENG

Patent number: 8944150Abstract: A heat dissipating device includes a chamber with an evaporation portion and a condensation portion, the chamber including a refrigerant. The chamber further includes an evaporation portion scraping brush provided corresponding to the evaporation portion, the evaporation portion scraping brush being able to sweep relative to an inner surface of the evaporation portion. A refrigerant liquid film is formed on the inner surface of the evaporation portion. Since the fluid refrigerant is uniformly applied to an inner surface of the evaporation portion to form a liquid film, the heat dissipating ability of the heat pipe heat dissipating device is improved, and the heat dissipating uniformity of the heat pipe heat dissipating device is enhanced. A heat dissipating method is also provided.Type: GrantFiled: August 4, 2009Date of Patent: February 3, 2015Assignee: Empire Technology Development LLCInventor: Hao Wang

Publication number: 20140262158Abstract: Provided is a modular pumped loop cooling apparatus including a cooling module and a pumping module, wherein the pumping module has an inlet coupling for mating with a corresponding outlet coupling of the cooling module when the cooling module is placed atop the pumping module. The modular pumped loop cooling apparatus is provided as a standalone unit that can be coupled to any one of a plurality of heat sinks having different heat loads. The cooling apparatus is therefore scalable to accommodate a wide range of cooling applications so that the apparatus does not have to be redesigned to accommodate a particular system.Type: ApplicationFiled: March 15, 2013Publication date: September 18, 2014Inventor: PARKER-HANNIFIN CORPORATION
