Patent number: 9574794Abstract: A radiator in particular for room heating, comprising a control or measurement unit accommodated in a container integral with the radiator and positioned so as to sustain the heat from the radiator as little as possible, while exploiting a cool air flow drawn by the same to cool the internal circuitry defining the unit. Said container is conveniently spaced apart from the radiator by means of insulating elements and a part of the same container is formed by a heat dissipator to which one or more electronic power elements included in said circuitry are thermally connected.Type: GrantFiled: March 10, 2010Date of Patent: February 21, 2017Assignee: I.R.C.A. S.P.A. INDUSTRIA RESISTENZE CORAZZATE E AFFINIInventors: Michele Peterle, Marco Argenton

Patent number: 9562727Abstract: A heat exchanger includes a plurality of heat exchange tubes and corrugated fins. The heat exchange tubes are spaced apart from one another in a vertical direction of the heat exchanger. The corrugated fins are each disposed between adjacent heat exchange tubes. Each of the corrugated fins includes crest portions, trough portions, and connection portions. The crest portions extend in an air passage direction of the heat exchanger. The trough portions extend in the air passage direction. The connection portions connect the crest portions and the trough portions. The number of the crest portions of each of the corrugated fins disposed between adjacent heat exchange tubes falls within a range of a designed number ±2. The designed number is a standard number.Type: GrantFiled: February 19, 2013Date of Patent: February 7, 2017Assignee: KEIHIN THERMAL TECHNOLOGY CORPORATIONInventors: Takayuki Fujii, Yoshihiko Seno, Shingo Suzuki

Patent number: 9551540Abstract: A lower space of a first header collecting pipe of a heat exchanger is, by partitions, divided into three communication chambers and a single mixing chamber. The mixing chamber communicates with the communication chamber through a through-hole of a lower horizontal partition, communicates with the communication chamber through a through-hole of a vertical partition, and communicates with the communication chamber through a through-hole of an upper horizontal partition. Gas-liquid refrigerant flows into the mixing chamber, and is mixed in the mixing chamber. Then, the refrigerant is distributed to the communication chambers. Thus, the wetness of refrigerant flowing into a flat tube is uniformized among the flat tubes, and performance of the heat exchanger can be fully achieved.Type: GrantFiled: November 22, 2012Date of Patent: January 24, 2017Assignee: DAIKIN INDUSTRIES, LTD.Inventors: Masanori Jindou, Yoshio Oritani, Takuya Kazusa, Yasutaka Ohtani, Junichi Hamadate, Yoshimasa Kikuchi

Patent number: 9554487Abstract: A apparatus for controlling heat transfer between portions of a substrate is provided. The apparatus includes a substrate including at least part of a hydraulic circuit, the hydraulic circuit including a plurality of microconduits, the plurality of microconduits including a first microconduit and a second microconduit. The apparatus further includes a liquid metal flowing through the hydraulic circuit and a magnetic field configured to selectively direct the flow of the liquid metal between the plurality of microconduits. The flow of the liquid metal through the hydraulic circuit transfers heat between a first portion of the substrate and the liquid metal.Type: GrantFiled: September 26, 2012Date of Patent: January 24, 2017Assignee: Elwha LLCInventors: Andrew F. Glew, Roderick A. Hyde, Jordin T. Kare, Lowell L. Wood, Jr.

Patent number: 9534856Abstract: There is provided a heat exchanger realizing downsizing, weight saving, and cost reduction in comparison with a conventional heat exchange element or heat exchanger. The heat exchanger is provided with a first fluid flow portion formed of a honeycomb structure having a plurality of cells partitioned by ceramic partition walls and extending from one end face to another end face in an axial direction to allow a heating medium as a first fluid to flow therein, and a second fluid flow portion formed of a casing containing the honeycomb structure therein, the casing having an inlet and an outlet for a second fluid, and the second fluid flowing on an outer peripheral face of the honeycomb structure to receive heat from the first fluid.Type: GrantFiled: June 8, 2012Date of Patent: January 3, 2017Assignee: NGK Insulators, Ltd.Inventors: Yoshio Suzuki, Tatsuo Kawaguchi, Shigeharu Hashimoto, Michio Takahashi

Patent number: 9528777Abstract: A heat exchanger is comprised of two heat exchanger sections, at least one of which is provided with a floating header to accommodate differential thermal expansion. The two heat exchanger sections are enclosed by an inner shell wall, and an external connecting passage is provided outside the inner shell wall, through which one of the fluids flows between the two heat exchanger sections. The external connecting passage is enclosed by an outer shell. The inner wall is provided with openings which communicate with the external connecting passage. The openings may be in the form of a substantially continuous gap or discrete openings. Specific examples of heat exchangers with this construction include a steam generator, a steam generator and combined catalytic converter, and a water gas shift reactor.Type: GrantFiled: June 29, 2012Date of Patent: December 27, 2016Assignee: Dana Canada CorporationInventors: Doug Vanderwees, Manaf Hasan, Jianan Huang, Brian E.

Patent number: 9518786Abstract: Apparatus (1) for storing energy includes a high pressure storage vessel (10) for receiving high pressure gas, the high pressure storage vessel (10) including a high pressure heat store including a first chamber housing a first gas-permeable heat storage structure (14); and a low pressure storage vessel (11,12) for receiving low pressure gas, the low pressure storage vessel (11,12) including a low pressure heat store including a second chamber housing a second gas-permeable heat storage structure (16,18. The first heat storage structure (14) has a mean surface area per unit volume which is higher than a mean surface area per unit volume of the second heat storage structure (16,18).Type: GrantFiled: February 24, 2011Date of Patent: December 13, 2016Assignee: Energy Technologies Institute LLPInventors: Jonathan Sebastian Howes, James Macnaghten

Patent number: 9470461Abstract: A heat exchanger having a collection tank having an internal chamber and a header connected to the collection tank and receiving a number of flat tubes through apertures in the header. A reinforcing member received within the collection tank and/or the header functions to reinforce the header and/or the collection tank in applications where these elements are subject to internal pressures that would otherwise deform the header and/or collection tank to an unacceptable extent. The heat exchanger may include a curved gasket on each flat tube to match the shape of the flat tubes and a curved header. Also, another gasket can be located between a metal or plastic collection tank and a plastic or metal header, respectively, to prevent leakage therebetween.Type: GrantFiled: November 3, 2008Date of Patent: October 18, 2016Assignee: Modine Manufacturing CompanyInventors: Brian Merklein, Gregg D. Olson, Mark Kazikowski, Jochen Orso, Jorg Wille, Roy J. Ingold, Joachim Wollmershäuser
