Abstract

A cooling system for dissipating heat from a heat source has a heat sink associated with an air moving device. The heat sink has a core member having a first surface adapted to contact at least a portion of the heat source. In addition, the core member has at least one outer peripheral surface. At least one cooling fin device having at least one inner peripheral surface and at least one cooling fin is associated with the core member wherein the inner peripheral surface of the cooling fin device is adjacent the outer peripheral surface of the core member. The air moving device is located opposite the first surface of the core member and forces air past the cooling fins in the general direction of the first surface. During operation of the cooling system, heat transfers from the heat source into the core member via the core member first surface. The core member transfers the heat to the outer peripheral surface where it is then transferred to the cooling fins. The cooling fins, in conjunction with the air of the air moving device, convect the heat to the surrounding atmosphere, thus, cooling the heat source.
