ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a rack for supporting a notebook computer above a flat surface, and more particularly to a cooling rack for notebook computer, which effectively carries heat away from the notebook computer supported thereon during the operation of the notebook computer.
Regular notebook computers are compact, and require less operation space. However, the mainframe of a notebook computer produces much heat during its operation. When operating a notebook computer on a flat surface, heat cannot be quickly carried away from the bottom side of the notebook computer. If the temperature of the mainframe of a notebook computer surpasses a critical lever for a certain length of time, the internal circuit and component parts of the mainframe of the notebook computer will be damaged.
SUMMARY OF THE INVENTION
The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a cooling rack for notebook computer, which is practical for use to support a notebook computer on a flat surface, and to effectively carry heat away from the notebook computer supported thereof. According to one aspect of the present invention, the cooling rack for notebook computer comprises a base frame defining a plurality of open chambers, a cover shell covered on the base frame and adapted to support a notebook computer, and a plurality of fans respectively installed in the open chambers of the base frame corresponding to respective suction holes on the cover shell and operated to induce currents of air in direction from the suction holes of the cover shell through the open chambers to the outside of the cooling rack. According to another aspect of the present invention, the cover shell comprises a plurality of bearing blocks adapted to support a notebook computer above the top side wall of the cover shell.
