Patent number: 7459784Abstract: Flexible circuitry is populated with integrated circuitry disposed along one or both of its major sides. Contacts distributed along the flexible circuitry provide connection between the module and an application environment. The circuit-populated flexible circuitry is disposed about an edge of a rigid substrate thus placing the integrated circuitry on one or both sides of the substrate with one or two layers of integrated circuitry on one or both sides of the substrate. The substrate form is preferably devised from thermally conductive materials and includes a high thermal conductivity core or area that is disposed proximal to higher thermal energy devices such as an AMB when the flex circuit is brought about the substrate. Other variations include thermally-conductive clips that grasp respective ICs on opposite sides of the module to further shunt heat from the ICs.Type: GrantFiled: December 20, 2007Date of Patent: December 2, 2008Assignee: Entorian Technologies, LPInventors: James Douglas Wehrly, Jr., James Wilder, Paul Goodwin, Mark Wolfe

Patent number: 7450389Abstract: A power semiconductor module has a heat-dissipation contact surface (16) for a thermally conductive connection to a cooling element (17). The module can be simply, cost-effectively and reliably fixed to the cooling element for the conduction of heat to the latter by at least one pressure element (18, 19) which is permanently connected to the power semiconductor module. When mounted, the pressure element (18) presses the heat-dissipation contact surface (16) against the cooling element (17).Type: GrantFiled: March 6, 2007Date of Patent: November 11, 2008Assignee: Infineon Technologies AGInventors: Thilo Stolze, Richard Boettcher

Patent number: 7443681Abstract: A heat dissipator of a signal transmission member for a display apparatus can sufficiently dissipate heat from devices of the signal transmission member and protect the devices, and includes a thermal conductive supporter for dissipating heat generated by a signal transmission member, which transmits electrical signals between a chassis member supporting a panel displaying image and including at least one device and a circuit unit separated from the chassis member to drive the panel. The thermal conductive supporter includes: a base portion formed of a thermal conductive material, and having a side surface contacting the chassis member and another side surface contacting the signal transmission member; and a recess portion oriented on the base portion toward the chassis member so that the at least one device does not contact the base portion.Type: GrantFiled: January 10, 2006Date of Patent: October 28, 2008Assignee: Samsung SDI Co., Ltd.Inventors: Sung-Won Bae, Ki-Jung Kim

Patent number: 7429720Abstract: The present invention relates to an electric radiating pipe capable of enhancing a heating efficiency in such a manner that a mixture of a porous operation medium and a volatile operation fluid is filled in a radiation pipe, and a porous operation medium is fast heated based on a viscosity difference, and a densely filled operation fluid is phase-changed to a high temperature vapor or a high temperature liquid based on a heated operation medium. In a radiating pipe that includes a certain shaped pipe body, and a heat wire passing through to the interior of the pipe body wherein both ends of the pipe body are sealed by a plugging cap, there is provided an electric radiating pipe that includes a porous non-flammable operation medium and volatile operation fluid being mixed and being filled into the interior of the pipe body.Type: GrantFiled: January 12, 2004Date of Patent: September 30, 2008Inventor: Hyung-Gon Kim

Patent number: 7430121Abstract: A heat sink fastener includes a main body, a piercing body and an operating member. The main body has a pressing part for pressing a heat sink toward a heat-generating component. An engaging part and a latching leg are disposed at opposite ends of the main body. The piercing body includes a piercing part piercing through the engaging part, and a latching part below the piercing part. The operating member includes a cam pivotally connected to the piercing part and rotatable between locked and unlocked positions. At the locked position, a protrusion formed on the cam abuts a lateral edge of the piercing part to prevent the operating member from spontaneously rotating back to the unlocked position. A bent flange is formed at a periphery of the cam and engages with the engaging part.Type: GrantFiled: September 7, 2006Date of Patent: September 30, 2008Assignees: Fu Zhun Precision Industry (Shen Zhen) Co., Ltd., Foxconn Technology Co., Ltd.Inventors: Cui-Jun Lu, Jin-Song Feng
