    摘要: An electronic device includes a shell and a centrifugal fan. The shell includes a top wall, a bottom wall parallel to the top wall, and a sidewall perpendicular to the top wall and the bottom wall. The centrifugal fan is arranged between the top wall and the bottom wall. The centrifugal fan defines a first inlet facing the top wall and a second inlet facing the bottom wall. The first inlet and the second inlet are slantwise to the top wall and the bottom wall of the shell.

    摘要: A fan includes a speed control circuit and a motor electrically connected with the speed control circuit. The speed control circuit includes an inputting circuit and a transforming circuit electrically connected with the inputting circuit. The inputting circuit supplies a constant current to the transforming circuit. The transforming circuit transforms the constant current to a fluctuating current and outputs the fluctuating current to the motor of the fan. The fluctuating current causes a rotation with a fluctuating speed to the motor of the fan.

    摘要: A cooling fan includes a housing, a cover arranged on the housing, and an impeller received in a space formed between the housing and the cover. The impeller includes a hub and a plurality of blades extending radially and outwardly from the hub. Each of the blades includes a windward surface and a leeward surface opposite to the windward surface. A porous layer is disposed on the leeward surface of each of the blades, adjacent to a free end thereof. The porous layer has one side surface attached to the leeward surface and an opposite side surface facing the windward surface of an adjacent blade.

    摘要: A thermal module includes a fin assembly, a heat spreader, a heat pipe connected between the fin assembly and the heat spreader, and a securing plate. The securing plate has at least three resilient members secured on a bottom surface thereof. Each of the resilient members has a capability to deform resiliently along a direction perpendicular to the bottom surface of the securing plate to resiliently press the heat spreader to an electronic component.
