Abstract
A cooling system for a circuit board employs a heat-conducing channel within the board. The channel is thermally coupled to an electrical device mounted on the board, and leads to an edge of the board. The edge of the board is coupled to a heat-dissipating can. The use of channels leading to the edges of the board allows a single can to dissipate heat for a plurality of boards and a plurality of devices.
