A heat exchanger core for a heat sink having a plurality of folded heat conductive fins. Each folded heat conducting fin has a front face, a back face spaced from the front face, a top connected between the front and back faces, open opposite sides that communicate with the atmosphere, and an air intake opening that extends vertically through the top for receipt of a supply of fan blown air. The fins are arranged face-to-face one another to establish laterally extending primary and supplemental air exhaust cavities through the heat exchanger core which run between the vertically extending air intake openings and the open opposite sides of the fins. Thus, the heat exchanger core will have non-linear air flow paths by which heat collected by the plurality of fins is blown into the atmosphere at the open opposite sides thereof. By virtue of the foregoing, the heat exchanger core provides maximum surface area, efficient heat transfer, and optimal air flow so that the heat generated by a source (e.g. a CPU) can be effectively collected and exhausted to the atmosphere.
