A heat sink is disclosed having an elongate, porous metal structure, including multiple sets of thermally conductive members. The members, which are interwoven, direct heat away from a heat producing component. The elongate structure of the matrix structure can be formed in a variety of predetermined forms, including a coiled structure or an elliptically coiled structure. Alternatively, the matrix structure is plated for added thermal conductivity between the sets of members. In addition, air flow is directed over the heat sink for added convection of heat. The heat sink is fabricated using a mesh of thermally conductive material such as copper or aluminum and can be provided with a plurality of protuberances. The heat sink is thermally bonded to the heat producing component. Alternatively, the heat sink has a ledge for sealing with a duct. A method for cooling a heat producing component is also disclosed. The method includes the steps of providing a heat sink structure as above, thermally coupling the heat sink structure to a heat producing component, and directing a fluid flow over the heat sink structure.

Process for producing tubular film from thermoplastic molten material

An apparatus and process for producing tubular film from thermoplastic molten material including a tubular housing having an axially-aligned interior defined inner surface, an elongated member including an outer surface disposed within the inner surface of the housing and spaced therefrom providing a passageway, and an alignment member having a plurality of annularly-spaced feed ports defining an inside surface, the alignment member securely connecting the elongated member to the housing, wherein the inner surface of the housing, the outer surface of the elongated member and the plurality of annularly-spaced feed ports define an annular-axially aligned passageway for allowing a balanced flow of thermoplastic material therethrough.
