Patent number: 7826214Abstract: A heat exchange structure includes elongated air ducts. Each air duct has a first opening and a second opening at two ends of the air duct to allow air to enter and exit the air duct, respectively. The heat exchange structure includes an exterior heat exchange surface and interior heat exchange surfaces, in which the exterior heat exchange surface is configured to receive thermal energy from heat generators that are mounted on the exterior heat exchange surface, and the exterior heat exchange surface dissipates a portion of the thermal energy received from the heat generators and transfers another portion of the thermal energy to the interior heat exchange surfaces. The interior heat exchange surfaces are in the elongated air ducts and configured to exchange thermal energy with air flowing in the air ducts, enhancing air flow in the air ducts by buoyancy of heated air.Type: GrantFiled: March 28, 2008Date of Patent: November 2, 2010Assignee: Hong Kong Applied Science and Technology Research Institute Co., Ltd.Inventor: Geoffrey Wen-Tai Shuy

Patent number: 7724516Abstract: Apparatus and methods for thermal conditioning equipment. In a preferred embodiment, an equipment enclosure comprises a body, a wall, a fluid port, and a fixture. The body defines an outer plenum and an inner chamber in the latter of which the fixture retains the equipment. The wall, which is between the outer plenum and the inner chamber, isolates the thermally conditioned first fluid from a second fluid in the inner chamber. Since the wall is thermally conductive it allows heat to be transferred between the outer plenum and the inner chamber. The fluid port is in communication with the outer plenum to allow the thermally conditioned first fluid to flow into the outer plenum. Baffle plates are also provided to distribute flow of the second fluid to the equipment.Type: GrantFiled: August 26, 2005Date of Patent: May 25, 2010Assignee: The Boeing CompanyInventors: Daniel Harder, Charles F.

Patent number: 7724121Abstract: An improved MEMS thermal actuator has a cantilevered beam and a conductive circuit having two driving arms, an inner arm adjacent to the cantilevered beam, and an outer arm adjacent to the inner arm. Current flows through the inner and outer arms to heat the conductive circuit, causing it to expand relative to the cantilevered beam. A tether ties the conductive circuit to the cantilevered beam, so that upon expansion, the conductive circuit causes the cantilevered beam to deflect about its anchor point. However, only the inner arm of the driving beam is coupled to the cantilevered beam. Since the outer arm of the conductive circuit is not coupled to the cantilevered beam, the overall stiffness of the actuator may be decreased. In addition, serpentines may be placed in the outer arm of the conductive circuit, in order to further decrease the stiffness of this beam. The actuator may therefore be made more efficient, in that the deflection of the cantilevered beam may be increased for a given input current.Type: GrantFiled: September 7, 2006Date of Patent: May 25, 2010Assignee: Innovative Micro TechnologyInventor: Paul J. Rubel
