Patent number: 6059116Abstract: Heat sinks and electrical components pre-coated with a layer of a material such as thermal grease are disclosed. Contamination and migration of the thermal grease is substantially reduced by covering the coated areas with a release liner that is removed prior to the assembly of the heat sink into a circuit board or other assembly. By providing a pre-coated heat sink, productivity can be enhanced, by increasing accuracy with which the thermal grease is applied, thus eliminating waste and clean up. Methods for pre-coating either a heat sink or the release liner with thermal grease are also disclosed. In preferred embodiments areas of the heat sink can be either fully coated, or portions electively coated, and the coating may be accomplished by a silk screening or pad printing process, which includes using an applicator head. The release liner is preferably provided with a pull-off tab to facilitate the removal of the release liner.Type: GrantFiled: June 18, 1997Date of Patent: May 9, 2000Assignee: Thermalloy, Inc.Inventors: Howard G. Hinshaw, Matthew C. Smithers

Patent number: 5897917Abstract: Heat sinks pre-coated with a layer of a material such as thermal grease are disclosed. Contamination and migration of the thermal grease is substantially reduced by covering the coated areas with a protective film that is removed prior to the assembly of the heat sink into a circuit board or other assembly. By providing a pre-coated heat sink, productivity can be enhanced, by increasing accuracy with which the thermal grease is applied, thus eliminating waste and clean up. Methods for pre-coating either a heat sink or the protective film with thermal grease are also disclosed. In preferred embodiments areas of the heat sink can be either fully coated,, or portions electively coated, and the coating is most preferably accomplished by a silk screening or pad printing process. The protective film is preferably provided with a tear off tab to facilitate the removal of the protective film.Type: GrantFiled: August 13, 1997Date of Patent: April 27, 1999Assignee: Thermalloy, Inc.Inventors: Howard G.

Patent number: 5486980Abstract: Heat sink apparatus for cooling large electronic devices is formed with a heat sink body having a plurality of pins extending outwardly from the base of the heat sink body and a rotary fan having a blowing surface mounted adjacent the outer extremity of the pins. The pins are separated by intersecting grooves providing a large surface area for the heat sink body. The surface area of the heat sink body is sufficiently large to provide a thermal impedance of substantially less than 1.0.degree. C./W and the volume occupied by the heat sink is sufficiently small to provide a volume performance value of less than about 6.degree. C. in.sup.3 /W.Type: GrantFiled: September 8, 1994Date of Patent: January 23, 1996Assignee: Thermalloy, Inc.Inventors: William D. Jordan, Howard G. Hinshaw

Patent number: 5464054Abstract: A mounting clip for securing a heat sink to a device package is secured to the heat sink by forming a groove in the heat sink, positioning the central body portion of the clip in the groove and deforming the wall of the groove to trap the clip in the groove. The clip is an elongated body with ends extending from the axis of its central body. The ends may be trapped or hooked in appropriate receivers on a frame or socket holding an electronic device package to secure the heat sink adjacent the device package.Type: GrantFiled: August 1, 1994Date of Patent: November 7, 1995Assignee: Thermalloy, Inc.Inventors: Howard G. Hinshaw, Keith R. Moulton, Donald L. Bland

Patent number: 4884331Abstract: Unitary heat sink apparatus for use in removal of heat from a heat generating component is disclosed which includes a heat sink body formed by extrusion. Parallel fins extend outwardly a first predetermined distance for the heat sink body and are separated by a first predetermined number of grooves of a first predetermined depth and width. The ratio of the height of the fins to the width of the grooves is approximately four to one. The first predetermined number of parallel grooves are gang sawed to a second predetermined depth to provide a second and greater predetermined height to the parallel fins such that the new ratio of the second predetermined height of the fins to the width of the parallel grooves is increased to at least six to one. In another embodiment, the heat sink is then rotated ninety degrees and a second predetermined number of grooves are gang sawed at right angles across and through the parallel fins to provide a predetermined number of pins extending outwardly from the heat sink body.Type: GrantFiled: October 26, 1988Date of Patent: December 5, 1989Assignee: Thermalloy IncorporatedInventor: Howard G.
