Abstract
A heat sink assembly includes a heat exchanging section having a thermally conductive sheet folded into alternating ridges and troughs defining spaced fins having first and second end edges. The folded sheet is formed into a generally cylindrical configuration defining an axis. The troughs form an inner segmented cylinder, the ridges form an outer segmented cylinder generally concentric with the inner cylinder and the fins radiate generally outwardly from the axis. A thermally conductive core is provided within the inner segmented cylinder defined by the troughs of the cylindrically folded sheet to transfer the heat to be dissipated from the heat generating component to the heat exchanging section. A retainer is engageable with the cylindrically folded sheet generally at the second end edges of the fins. The heat exchanging section may be mounted above a base plate, with the first end edges of the fins being between the base plate and the second end edges of the fins and complementary interengaging latches are provided between the retainer and the base plate to hold the heat exchanging section therebetween.
