Abstract
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.
