Heat sink assembly

摘要

A heat sink assembly includes a heat exchanging section formed by a thermally conductive sheet folded into alternating ridges and troughs defining generally parallel spaced fins having opposite end edges. The folded sheet is formed into a generally cylindrical configuration whereby the troughs form an inner segmented cylinder and the ridges form an outer segmented cylinder generally concentric with the inner cylinder. The heat sink assembly may include a heat conductive rod dimensioned to engage the troughs of the thermally conductive sheet. The ridges of the thermally conductive sheet may also contain apertures to allow air to fully circulate through the fins. The heat sink assembly may also include a fan and a thermally conductive base plate.
