Together, the tube, the header, and the elastic sleeve can at least partially define a flow path for a working fluid.Type: ApplicationFiled: July 10, 2007Publication date: January 17, 2008Applicant: MODINE MANUFACTURING COMPANYInventor: Steven P.

Patent number: 7272000Abstract: A heat dissipating structure of an interface card is applied in an electronic device. The structure includes a heat dissipating apparatus attached to a circuit board of the electronic device, wherein the heat dissipating apparatus comprises a heat sink and a fan received in a room of the heat sink; and an interface card electrically connected to the circuit board of the electronic device via a connector. At least a surface of the interface card that is mounted with semiconductor components is mounted on top of a part of the heat dissipating apparatus in a faced-down manner to dissipate heat generated during operations of the semiconductor components to an external environment through the heat sink and the fan.Type: GrantFiled: March 31, 2005Date of Patent: September 18, 2007Assignee: Inventec CorporationInventor: Spring Liu

Patent number: 7267160Abstract: In order to provide a heat exchanger with casing having a multiplicity of tubes through the interiors of which a high-temperature gas for heating flows, wherein the thermal stress is smoothly accommodated and wherein a fluid to be heated or a heating fluid flows uniformly through the outsides of the tubes, a multiplicity of flat tubes are joined at their opposed ends to a pair of discoidal tube plates, the outer periphery of the flat tubes being enclosed by an inner cylinder having a rectangular cross-section except the opposed end portions of the flat tubes, with a pair of baffle plates being disposed at the opposed ends of the inner cylinder. The pair of baffle plates are covered with an circular outer cylinder having a corrugated portion that is thermally expandable, with an inlet and an outlet for the fluid to be heated or the heating fluid positioned between the pair of baffle plates and the tube plates.Type: GrantFiled: July 23, 2003Date of Patent: September 11, 2007Assignee: T.RAD Co., Ltd.Inventors: Shuko Shincho, Susumu Ichikawa, Masaki Saito, Tadamichi Aoyama

Patent number: 7231960Abstract: An object of the present invention is to provide a cooler for cooling both sides (top and bottom surfaces) of a semiconductor device, wherein the variation of pressing force on flat cooling tubes holding a semiconductor device is reduced, thereby uniformly dissipating the heat generated by the semiconductor device. When the holding plates press the flat cooling tubes and semiconductor modules by tightening the nut, the dimensional tolerances in the stacking direction are absorbed by the deformable portions in the inlet and outlet headers. A spacer may be employed inside the flat cooling tubes in order to suppress the deformation of the flat cooling tubes along the stacking direction.Type: GrantFiled: December 12, 2003Date of Patent: June 19, 2007Assignee: Denso CorporationInventor: Yasuyuki Sakai

Patent number: 7210521Abstract: A heat medium distributor for an air inlet system having multiple heat exchangers includes a box-like housing, which is divided by a dividing wall into a first flow chamber, which is used as the forward collection pipe, and a second flow chamber, which is used as the return collection pipe. For each heat exchanger to be connected, a forward connection nozzle branches off the first flow chamber and for each heat exchanger to be connected, a return connection nozzle opens into the second flow chamber. The arrangement of the connection nozzles is such that all flow paths of the heat medium through the various heat exchangers and the distributor are of equal length. The heat medium distributor replaces traditional heat medium distributors which are produced by welding together individual pieces of pipe, and which are structurally relatively large and therefore expensive, and in general cannot be housed in the housing of the air inlet system.Type: GrantFiled: June 3, 2004Date of Patent: May 1, 2007Assignee: Eisenmann Maschinenbau KGInventor: Wolfgang Rauser

Patent number: 7100680Abstract: The apparatus is a heat pipe with superior heat transfer between the heat pipe and the heat source and heat sink. The heat pipe is held tightly against the heat source by mounting holes which penetrate the structure of the heat pipe but are sealed off from the vapor chamber because they each are located within a sealed structure such as a pillar or the solid layers of the casing surrounding the vapor chamber. Another feature of the heat pipe is the use of more highly heat conductive material for only that part of the wick in the region which contacts the heat source, so that there is superior heat conductivity in that region.Type: GrantFiled: August 9, 2005Date of Patent: September 5, 2006Assignee: Thermal Corp.Inventors: Peter M. Dussinger, Thomas L. Myers

Patent number: 7077189Abstract: A fluid heat exchanger assembly cools an electronic device with a cooling fluid supplied from a heat extractor (R, F) to a plurality of tubes extending between header tanks in an upper portion of a housing. A refrigerant is disposed in the lower portion of the housing for liquid-to-vapor transformation. The tubes are radially flexible to vary the volume of the tubes for modulating the flow of coolant liquid through the tubes in response to heat transferred by an electronic device to the lower portion of the housing.Type: GrantFiled: January 21, 2005Date of Patent: July 18, 2006Assignee: Delphi Technologies, Inc.Inventors: Ilya Reyzin, Mohinder Singh Bhatti
