Abstract
Description
- The present invention relates to a heat dissipation apparatus, and more particular, to a heat dissipation apparatus including two sets of fans installed within a single enclosure. Therefore, an enhanced dissipation effect is resulted because the speed and pressure generated by rotation of the fan can be adjusted according to specific requirement, while the assembly convenience is improved.
- To enhance overall wind speed and pressure, two
heat dissipation fans FIG. 1 . Thereby, the damage of the system caused interruption of any of the fans can be avoided. However, to assemble thefans fans - When the
fans fans ribs 21A for reinforcing stability of the attachment. When thefirst fan 2A rotates to generate an air flow, the air flow is easily interrupted by theribs 21A to cause turbulence. When the turbulence is circulating into thefan 2A′, the wind speed and pressure generated by thefan 2A′ is seriously affected. Even when thefan 2A′ remains stationary when thefan 2A rotates, the wind pressure will be lowered by the installation of thefan 2A′. The serial connection of thefans - The present invention provides a heat dissipation apparatus which integrates two sets of fans into a single enclosure, such that assembly convenience is greatly improved, while the heat dissipation efficiency is enhanced.
- The heat dissipation apparatus provided by the present invention is operative to adjust the wind speed and pressure of the air flow generated by the sets of fans.
- The heat dissipation apparatus comprises an enclosure in which a fan seat is laterally disposed. The fan seat divides an interior space of the enclosure into two chambers. The heat dissipation apparatus further comprises a shaft extending through a center of the fan seat across both the chambers. In each of the chambers, a set of fan is installed about the shaft. Each set of fans includes a coil set, a magnetic device and a set of blades.
- The fan seat includes at least one stationary guiding blade to guide the air flow from one set of fan into the other. Therefore, the turbulence caused by the air flow generated by the other set of fan is prevented. The wind speed and pressure can thus be adjusted as required.
- These and other objectives of the present invention will become obvious to those of ordinary skill in the art after reading the following detailed description of preferred embodiments.
- It is to be understood that both the foregoing general description and the following detailed description are exemplary, and are intended to provide further explanation of the invention as claimed

Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.
- The present invention provides a
heat dissipation apparatus 10 as shown inFIG. 2 . Theheat dissipation apparatus 10 includes an enclosure orhousing 1, in which a lateral fan seat 12 (as shown inFIG. 4 ) is integrally formed. Thefan seat 12 divides an interior space of theenclosure 10 into anupper chamber 13 and alower chamber 14 to accommodate two sets offans fan seat 12 includes a substantially circular dish and at least one guiding blades 121 (stationary blade) extending radially from a is periphery of the body dish. Theheat dissipation apparatus 10 further comprises ashaft 15 extending through a center of thefan seat 12 into both theupper chamber 13 and thelower chamber 14. - The upper and
lower chambers fans shaft 15, respectively. Thefans hubs shaft 15,hollow bushings shaft 15 and thehubs hubs fans shaft 15 by means ofball bearings rings springs fan sets magnetic strips magnetic frames hubs - Referring to
FIGS. 2 and 4 , during assembly, thecoil sets magnetic strips magnetic frames hubs fans bushings hubs fans fan seat 12, and the while fan assembly is then disposed in theenclosure 1. To secure thefans fan seat 12, the through holes of thebushings shaft 15 at two sides of thefan seat 12. Once theshaft 15 is inserted into thehubs rings springs shaft 15. Thereby, a heat dissipation apparatus with twofan sets FIG. 3 . - In the present invention, the integrally fan laterally disposed in the enclosure divides the interior space of the enclosure into two chambers, such that two fan sets can be installed in a single enclosure.
