摘要:
A thermally conductive and electrically insulative polymer composition and a method for creating the same is provided. Thermally conductive filler material is coated with a thermally conductive and electrically insulative coating material and mixed with a base polymer matrix. The mixture is molded into the desired shape. The electrically insulative coating material prevents the transfer of electricity through the filler material thus resulting in an electrically insulative composition.

摘要:
A heat sink assembly for removing heat from an object having an outer surface includes a main body with an object receiving seat. A pair of flexible securing tabs are connected to the free edge of the open end of the main body which emanate into the open end of the main body. A heat dissipation members emanate from the outer surface of the main body to assist in dissipating the heat received by the main body from the heat generating object. The main body, the pair of flexible securing tabs and heat dissipating members are integrally formed with one another of a thermally conductive elastic or elastomeric material. An object to be cooled is inserted into the object receiving seat of the main body and retained in the seat and in communication with the inner surfaces of the main body by the pair of flexible securing tabs.
