Patent number: 7692926Abstract: The present invention is a MEMS-based two-phase LHP (loop heat pipe) and CPL (capillary pumped loop) using semiconductor grade silicon and microlithographic/anisotropic etching techniques to achieve a planar configuration. The principal working material is silicon (and compatible borosilicate glass where necessary), particularly compatible with the cooling needs for electronic and computer chips and package cooling. The microloop heat pipes (?LHP™) utilize cutting edge microfabrication techniques. The device has no pump or moving parts, and is capable of moving heat at high power densities, using revolutionary coherent porous silicon (CPS) wicks. The CPS wicks minimize packaging thermal mismatch stress and improves strength-to-weight ratio. Also burst-through pressures can be controlled as the diameter of the coherent pores can be controlled on a sub-micron scale. The two phase planar operation provides extremely low specific thermal resistance (20-60 w/cm2).Type: GrantFiled: October 31, 2007Date of Patent: April 6, 2010Assignee: Progressive Cooling Solutions, Inc.Inventors: H.

Publication number: 20090161311Abstract: It's a type of top mount surface airflow heatsink, utilizing the upper ceiling wall separated by an air gap, working together with the upper surface of a heating device (microprocessor) producing an air current. It's a simple device, with a low cost using the Reynolds Equation Re=(?umd)/??2,500; with ? being the fluid density, um being the free-stream fluid velocity, d being the pipe distance or diameter, ? being the fluid viscosity. Since the airflow produces air turbulence, it causes the frequent heat exchanges in the air. It also causes the obvious temperature changes within the different layers of air. Therefore, it increases tremendously, the efficiency of dissipating the heat. It requires only the input of the air. The operation is simple and it allows the usage of even higher heat generating devices. Thus it promotes the alternative usage of this top mount heatsink device within the installation of circuit board components.Type: ApplicationFiled: November 1, 2007Publication date: June 25, 2009Applicant: Chroma Ate, IncInventor: I-Shih Tseng

Publication number: 20090161313Abstract: A heat dissipating structure for a heat source includes a position-adjusting unit, a first heat dissipating element, a second heat dissipating element and a first heat conducting element. The position-adjusting unit has an elastic element. The first heat dissipating element is connected with the position-adjusting unit. The second heat dissipating element contacts with the heat source. One end of the first heat conducting element contacts with the first heat dissipating element, and the other end of the first heat conducting element contacts with the second heat dissipating element. The position-adjusting unit adjusts the position of the first heat dissipating element relative to the second heat dissipating element by the elastic element.Type: ApplicationFiled: December 10, 2008Publication date: June 25, 2009Inventors: Hsueh-Lung Cheng, Ming-Feng Tsai
