Abstract: An advection fan includes a fan frame, an impeller and a cover plate. The fan frame has a bottom plate and a lateral wall. A shaft seat is arranged on the bottom plate. The lateral wall surrounds the shaft seat and has an inner peripheral face. The lateral wall includes first and second air-guiding portions. An air inlet and an air outlet are formed between the first and second air-guiding portions. The first air-guiding portion includes a first guiding face intersecting the inner peripheral face by a first included angle, which is smaller than 180 degrees. The second air-guiding portion includes a second guiding face. A distance between the first and second guiding faces is gradually reduced from the air inlet towards the center of the fan frame. The impeller is rotatably coupled with the shaft seat. The cover plate is coupled with the lateral wall.

Abstract: A lamp includes a housing, a heat sink, a cooling fan and a light-emitting module. The housing has an assembling opening and an electrical connection member on two ends thereof, wherein the housing further comprises an inner wall and a portion of the inner wall adjacent to the assembling opening is an air-guiding wall. The heat sink has a base plate disposed at the assembling opening of the housing, wherein the base plate has at least one partitioning board defining an air channel of the heat sink. A first air-guiding opening is formed between the air-guiding wall and the at least one partitioning board, and a second air-guiding opening is formed between the air channel and the air-guiding wall. The cooling fan is coupled with the heat sink and has an impeller. The light-emitting module is coupled with the base plate of the heat sink.

Abstract: The present invention relates to a linear micro motor having an forward and backward reciprocating motion. The linear micro motor includes at least two actuators which can be a scratch drive actuator (SDA), a bounce drive actuator (BDA) or a combination thereof. To achieve the reciprocating motion, the linear micro motor is arranged in a way that at least two SDAs are disposed in an opposite manner, at least two BDAs are disposed in an opposite manner, or at least a SDA and at least a BDA are disposed in an identical manner. The linear micro motor of the present invention in accordance with the arrangement of the actuators can be realized to be applicable to a digital camera or camera phone by the advancing and receding linear motion caused by the motion of the actuators to achieve a focus-adjustable liquid crystal lens.

Abstract: The invention relates to a cooling device, which comprises a cooling fan and a heatsink. The heatsink is directly attached to the heating element to absorb its heat and the cooling fan is disposed on top of the heatsink to dissipate the heat. The heatsink includes a central heat dissipation body and a plurality of fins extending from the periphery of the central heat dissipation body. The central heat dissipation body has a fully-sealed hollow chamber filled with a cooling liquid and disposed an agitator. The agitator is disposed a magnetic element, and where the magnetic element corresponds to the rotor of the cooling fan must have a magnetically-attracting and mutually-dragging device in operation. By way of the magnetic attraction between the rotor of the cooling fan and the agitator, a better heat dissipation effect is secured, the chamber remains a fully-sealed room, and the cooling liquid overflow issue can be ruled out accordingly.

Abstract: A stator comprises a bobbin with a winding wound therearound and having a central hole. Pole plates are mounted to both sides of the bobbin. Each pole plate includes a plurality of poles and a central tubular portion. The poles of the pole plate attached to a side of the bobbin and the poles of the pole plate attached to the other side of the bobbin are alternately disposed. A magnetically conductive tube is extended through the central hole of the bobbin and the central tubular portions of the pole plates.
