The power supply includes a casing and a power-supplying module received in the casing. The heat-dissipating assembly includes a fan received in the casing and located outside the power-supplying module. The partitioning plate and the casing are respectively provided with a plurality of first heat-dissipating holes and second heat-dissipating holes. The first heat-dissipating holes and the second heat-dissipating holes are positioned to correspond to the fan. The airflow caused by the fan drives the air inside the housing to flow out of the housing via the first heat-dissipating holes and the second heat-dissipating holes. In this way, the heat-dissipating efficiency can be improved without affecting the arrangement of other electronic devices in the housing.Type: GrantFiled: April 7, 2010Date of Patent: January 3, 2012Assignee: Super Micro Computer Inc.Inventor: Te-Chang Lin

Patent number: 8089765Abstract: A liquid submersion cooled computer that includes a seamless, extruded main body used to form a liquid-tight case holding a cooling liquid that submerges components of the computer. By forming the main body as a seamless extrusion, the number of possible leakage paths from the resulting liquid-tight case is reduced. No seams are provided on the main body, and there are no openings through the walls of the main body, so liquid cannot leakage through the main body. Any leakage paths are limited to joints between the main body and end walls which are sealingly attached to the main body to form the liquid-tight case.Type: GrantFiled: July 14, 2011Date of Patent: January 3, 2012Assignee: Hardcore Computer, Inc.Inventor: Chad Daniel Attlesey

Patent number: 8081470Abstract: A mechanism for the heat sink to adhere to the transceiver inserted in the cage is disclosed. The heat sink provides a guide in the side thereof, while, the cage provides a slit in the side. A pair of elastic tabs is diagonally formed in the slit. The transceiver slides the heat sink rearward as the insertion thereof into the cage, then, the guide of the heat sink slips down the rear tab in the slit, which presses the heat sink downward to adhere to the transceiver. The heat conducting path from the transceiver to the heat sink is formed.Type: GrantFiled: December 10, 2008Date of Patent: December 20, 2011Assignee: Sumitomo Electric Industries, Ltd.Inventors: Kazushige Oki, Hiromi Kurashima

Patent number: 8081474Abstract: One embodiment of the present invention sets forth a heat spreader module for dissipating thermal heat generated by electronic components. The assembly comprises a printed circuit board (PCB), electronic components disposed on the PCB, a thermal interface material (TIM) thermally coupled to the electronic components, and a heat spreader plate thermally coupled to the TIM. The heat spreader plate includes an embossed pattern. Consequently, surface area available for heat conduction between the heat spreader plate and surrounding medium may be increased relative to the prior art designs.Type: GrantFiled: September 2, 2008Date of Patent: December 20, 2011Assignee: Google Inc.Inventors: Wael O.

Patent number: 8081463Abstract: A water-cooled communication chassis includes a chassis body and a water cooling unit. The chassis body includes at least one heat receiving portion, at least one heat dissipation portion, and at least one first water pipe system. The first water pipe system has a front part extended through the heat receiving portion and a rear part arranged on the heat dissipation portion, so that heat absorbed by the heat receiving portion is transferred via the first water pipe system to the heat dissipation portion and dissipated therefrom into ambient air. The water cooling unit communicates with the first water pipe system and drives a cooling fluid stored therein to circulate in between the first water pipe system and the water cooling unit, so that the heat absorbed by the heat receiving portion can be quickly and continuously carried away from the communication chassis by the circulating cooling fluid.Type: GrantFiled: June 16, 2009Date of Patent: December 20, 2011Assignee: Asia Vital Components Co., Ltd.Inventors: Huang Chiu-Mao, Huang Chang-Mou
