Abstract:

Disclosed herein is a cooling device primarily for cooling integrated circuits or other electronic devices during operation. The cooling device may include a heat sink portion and a fan, or other air movement device. The outer periphery of the heat sink portion may be formed with outwardly extending lobes, leaving recessed areas between the lobes. The lobes may be sized and located so as to correspond to heat concentration areas on an electronic device package. In this manner, heat sink material may be concentrated adjacent heat concentration areas where more heat removal is required. The overall mass and size of the heat sink portion may, thus, be reduced without significantly impairing the ability of the cooling device to remove heat from an electronic device. The heat sink portion may also be provided with an open space located beneath the base of the fan in order to insulate the motor of the fan from the heat sink base and, thus, reduce the amount of heat which transfers from the heat sink base to the fan motor.
