Abstract: This specification discloses a heat sink for coolers. The heat sink contains a heat conductive element, a heat dissipating shell covering over the heat conductive element, and a plurality of heat dissipating fins installed on the heat dissipating shell. The heat conductive element is comprised of a heat conductive plate and a heat conductive block installed at the center thereof. The area of the lower surface of the heat conductive block is greater than that of the upper surface thereof. When the lower surface of the heat conductive plate is in contact with a device that needs heat dissipation, the heat conductive block increases the heat conducting volume at the center of the heat conductive plate, so that the heat produced by the device can be released at an optimal rate.

Abstract: The present invention provides a digital camera DIY wireless photo print device. The device comprises a billing box, a wireless image-receiving unit, a processor, a monitor, and a photo printer. Wherein, the processor includes a plurality of control and IrDA protocol-processing programs to control the other units that are connected to the processor. The billing box provides a variety of payment methods. The monitor displays the two-way communication between the device and the user, and also displays the status of the image file transmission. The wireless image-receiving unit receives the optic signal of the image file, processes the photo-electronic transformation, and outputs an image file data to the processor. The processor controls the photo printer to print and output the photo.

Abstract: A fastening device is used to tightly attach the heat sink on an electronic element. The fastening device includes an elastic arm, a first latch element and a second latch element. The elastic arm has a first axial part, a second axial part, and a press part. The first latch element is secured to one side of the socket for mounting the electronic element thereon and pivotally coupled to the first axial part, and the second latch element is pivotally coupled to the second axial part. As the elastic arm turns about the first latch element and crosses the heat sink, the second latch element is allowed to be fastened onto another side of the socket. Thus, the press part of the elastic arm would urge against the heat sink to enable the heat sink to be tightly attached on the electronic element.

Abstract: A cooling fan with high heat-dissipating performance includes a plurality of blades; and a frame for receiving the blades therein, wherein the frame has a reduced height for exposing the blades to outside of the frame so as to allow air to enter into the frame via a top portion and a peripheral portion of the blades to improve air introduction and heat dissipating efficiency of the cooling fan. A cover may be mounted to a top surface of the frame, and formed with a plurality of openings for allowing air to enter into the frame through the openings; such an arrangement cam effectively enhance air intake and working efficiency of the cooling fan.
