Patent ID: 8081475

Claim:
A trolling motor heat sink assembly, the heat sink assembly comprising: a heat sink adapter fashioned in a cylindrical shape, the heat sink adapter having an outer surface for maintaining surface contact with a planar surface of a power device, wherein a first end of the heat sink adapter is fastened to the power device; a motor column of the trolling motor, the heat sink adapter having an inner surface for receiving the motor column in to a second end of the heat sink adapter and maintaining surface contact with an outer surface of the motor column such that heat generated by the power device is dissipated through the heat sink adapter and the motor column, wherein the heat sink adapter secures the motor column in an operating position; an insulator pad fitted on the first end of the heat sink adapter; and a controller board including a set of power connectors, the set of power connectors electrically coupling the power device with a top surface of the controller board through an aperture of the controller board, wherein the insulator pad electrically insulates the heat sink adapter from the controller board, and further wherein the insulator pad provides a seal between the heat sink adapter and the controller board.
