Patent number: 7013555Abstract: The present invention discloses a method of providing an integral thermal interface on an interface surface of a heat dissipation device, such as a heat sink. In accordance with the present invention, the phase change material is applied directly onto the interface surface of the heat sink to form an integral interface layer directly on the heat sink during the manufacturing process. This process includes the steps of providing a heat dissipating device having an interface surface, liquefying the phase change material at a controlled temperature so as to decrease the material viscosity to a flowable form, applying the liquefied phase change material directly onto the mating surface of the heat dissipating device either by directly dispensing the material, screen printing or stencil printing and cooling the material causing it to cure on the surface of the heat dissipating device.Type: GrantFiled: August 20, 2002Date of Patent: March 21, 2006Assignee: Cool Shield, Inc.Inventor: Kevin A.

Patent number: 6896045Abstract: The present invention discloses a thermal transfer interface having an integrally formed means for fastening and maintaining intimate thermal contact between a heat generating device and a heat-dissipating device. The interface of the present invention includes two components, a compressible thermal transfer component having a first thickness and an adhesive fastening component having a second thickness that is less than the first. The first component, the thermal transfer element, includes a base polymer matrix compound that is loaded with a thermally conducting filler that imparts thermally conductive properties to the net shape moldable material. The polymer base matrix is preferably a highly compressible material such as an elastomer. The second component of the present invention is a pressure sensitive adhesive component. The adhesive is applied adjacent to the thermal transfer element or in an alternating pattern throughout a base field of thermal transfer material.Type: GrantFiled: October 21, 2002Date of Patent: May 24, 2005Assignee: Cool Shield, Inc.Inventor: Jeffrey Panek

Patent number: 6651732Abstract: A composite heat dissipation assembly having a net shape injection molded thermally conductive elastomeric heat sink and at least one integral heat pipe is provided in the present invention. The molded conformable heat sink is formed from a base elastomeric material that is loaded with thermally conductive filler. The base material is mixed with the filler and net shape molded to form the outer geometry of the assembly. Within the geometry of the part an integral channel is formed that is capable of receiving a heat pipe. The channel is formed to have an opening that is slightly smaller than the outer cross-sectional dimensions of the heat pipe. When the heat pipe is pressed into the channel a portion of the elastomeric material is compressed and the reactionary force of the compressed material firmly presses the elastomer into thermal communication with the outer surface of the heat pipe.Type: GrantFiled: August 26, 2002Date of Patent: November 25, 2003Assignee: Cool Shield, Inc.Inventor: E.
