Abstract:
A heat dissipation apparatus has an enclosure, in which a lateral fan seat is integrally formed with the enclosure. The lateral fan seat divides the interior space of the enclosure into an upper chamber and a lower chamber. An axis is installed across the upper and the lower chambers through a center of the fan seat. A coil set, a magnetic element and a plurality of blades are mounted about the axis in each of the upper and lower chambers. Thereby, two sets of fans are formed in a single enclosure to increase the heat dissipation effect while the assembly convenience is improved.

Abstract:
Disclosed are a holographic reconstructing device and its application for portable electronic products. The holographic reconstructing device includes a compound hologram (9), a hologram seat (91), and a rebuilding light source (12). The compound hologram (9) is a flat-disk contour and disposed on the hologram seat (91). The rebuilding light source (12) is an LED and disposed under the hologram seat (91). The LED takes advantage of a small magnitude, less electricity consumption, simplified components, and a narrow bandwidth to definite a rebuilt image. The application of the flat-disk compound hologram is in a smooth-lying placement while reconstructing, which preferably occupies less space and facilitates user's observation as the rebuilt image is placed on the top of the compound hologram. The embedding of the holographic reconstructing device into the products would not affect the dimension of the products, thereby exhibiting realistic images on an individual space and forming a strong visual, clear impression, and a newly entertaining effect.
