Internal partitions divide the space enclosed by the front, back, side, top and bottom walls into multiple compartments for housing different types of components. The ventilated base forms air-intake ports for admitting ambient air into a plurality of the compartments, and the ventilated roof forms air-exhaust ports for allowing air to be exhausted from the compartments. As air inside the enclosure is heated by the switchgear, the hot air rises through the switchgear compartments and is exhausted through the top air-exhaust ports, and replacement ambient air is drawn into the bottoms of the compartments through the air-intake ports.Type: GrantFiled: February 22, 2010Date of Patent: May 31, 2011Inventors: Gregory O. Motley, Dale Waynick, Eldridge R. Byron, Abraham de la Cruz

Patent number: 7952870Abstract: A computer enclosure includes a casing defining a ventilation hole at one side thereof, a power supply and a cooling fan received in the casing. Heat generated by the power supply is taken out by an airflow generated by the cooling fan to an outside of the casing via the ventilation hole. At least one cover sheet covers the ventilation hole of the casing. One side of the cover sheet is pivotally connected to the casing so that the cover sheet is rotatable with respect to the casing. When the cooling fan works, an airflow produced by the cooling fan flows to the ventilation hole and pushes the cover sheet to rotate with respect to the casing, and thus the ventilation hole is exposed; when the cooling fan ceases to work, the cover sheet falls off due to a weight thereof and the cover sheet fully covers the ventilation hole.Type: GrantFiled: February 2, 2010Date of Patent: May 31, 2011Assignees: Hong Fu Jin Precision Industry (ShenZhen) Co., Ltd., Hon Hai Precision Industry Co., Ltd.Inventor: Hai-Qing Zhou

Publication number: 20110110041Abstract: A heat dissipation structure of an electronic apparatus includes a bendable vapor chamber with a large area. A small section of the vapor chamber is arranged to contact with the heat source of the electronic apparatus and a large remaining section of the vapor chamber contacts with an internal wall of the chassis of the electronic apparatus through appropriate bending. The working fluid in the vapor chamber absorbs the heat generated by the heat source and vaporizes. The heat-carrying vapor spreads within the vapor chamber to condense on a large condensation zone. The released heat is then dissipated to the atmosphere via the large area of the chassis and the heat dissipating fin structure thereon. Therefore, the heat dissipation structure provides efficient passive heat dissipation.Type: ApplicationFiled: February 19, 2010Publication date: May 12, 2011Inventor: Shwin-Chung WONG

Publication number: 20110110036Abstract: The present invention discloses a cooling fin assembly for Photo Voltaic Solar (PVS) panels providing an improved passive cooling of the PVS panels. Cooling fins as such do provide a good local cooling effect underneath the contacting surface of the fins. However, due to uneven air streams around the cooling fins, the temperature difference across a transversal direction relative to the direction of the fins may be high. This causes a severe degradation of the cooling systems effectiveness, and the resulting output form the PVS panel. According to the disclosure of this invention, an arrangement of transversal heat conducting materials provides a heat bridge providing a thermal relaxation time below a predefined threshold across the whole back side of the PVS panel, thereby improving the overall cooling effect of the PVS panel.Type: ApplicationFiled: March 9, 2009Publication date: May 12, 2011Inventors: Mark Buchanan, Gaute Dominic Magnussen, Lars Dysterud

Patent number: 7940528Abstract: An electronic device includes a casing, a thermal generating element, and a heat sink. The thermal generating element is disposed within the casing and operates to produce thermal energy. The heat sink includes a thermal transfer plate and a plurality of movable thermal transfer members. The thermal transfer plate contacts the thermal generating element and includes a plurality of recesses. Each of the movable thermal transfer members has a weight end and a free end. The weight end is accommodated in the recess. The thermal energy produced by the thermal generating element is conducted to the movable thermal transfer members via the thermal transfer plate. When the casing is tilted by a certain angle, the movable thermal transfer member swings relative to the thermal transfer plate, such that the free end thereof points to a direction opposite to that of an acceleration of gravity under a normal state.Type: GrantFiled: August 11, 2009Date of Patent: May 10, 2011Assignee: Inventec CorporationInventors: Feng-Ku Wang, Ting-Chiang Huang, Shaw-Fuu Wang, Sheng-Jie Syu
