Cooling rack for notebook computer

[0002] 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.

[0003] 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.

[0004] 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.

[0005] FIG. 1 is an applied view of the present invention, showing the cooling rack used with a notebook computer.

[0006] FIG. 2 is an elevational view of the cooling rack for notebook computer according to the present invention.

[0007] FIG. 3 is an exploded view of the cooking rack for notebook computer according to the present invention.

[0008] FIG. 4 is a top plain view of the cooking rack for notebook computer according to the present invention.

[0009] FIG. 5 is a schematic drawing showing the fans of the cooking rack operated according to the present invention.

[0010] FIG. 6 is a side view in section of the present invention, showing a notebook computer supported on the cooking rack and the fan operated.

[0011] Referring to FIGS. from 1 through 3, a cooling rack for notebook computer in accordance with the present invention is generally comprised of a base frame 1, a cover shell 2, and a plurality of fans 3. The cover shell 2 is a flat shell covered on the base frame 1, comprising a plurality of bearing blocks 22 raised from the top side wall thereof and adapted to support a notebook computer 4, and a plurality of suction holes 21. The base frame 1 comprises a plurality of open chambers 11 of substantially R-shaped profile arranged in parallel corresponding to the suction holes 21 of the cover shell 2 and extended to one side thereof, and a plurality of tubular mounting rods 115 respectively fastened to the cover shell 2 by screws 116. Each open chamber 11 comprises a fan receiving space 111, an upright shaft 114 disposed at the center of the fan receiving space 111 and adapted to hold one fan 3, and an air outlet 112 adapted to guide currents of air from the fan receiving space 111 to the outside of the base frame 1. A rechargeable battery 6 and an electronic control circuit board 5 are installed in the base frame 1, and adapted to control the operation of the fans 3. Electric power connectors 113 are installed in the base frame 1. The electric power connectors 113 include one power input connector adapted to receive AC power supply from the socket for cigarette lighter of a motor vehicle for the cooling rack (the rechargeable battery 7 and the fans 3), and a power output connector for providing the necessary working voltage to the notebook computer 4.

[0012] Referring to FIGS. from 4 through 6, the notebook computer 4 is supported on the bearing blocks 22 of the cover shell 2, and the fans 3 are operated to induce currents of air, enabling heat to be quickly carried away from the notebook computer 4 through the suction holes 21 of the cover shell 2 and the air outlet 112 of each open chamber 11 of the base frame 1. Because the bearing blocks 22 keeps the bottom side wall of the notebook computer 4 from touching the top side wall of the cover shell 2, air is allowed to circulate through the space between the bottom side wall of the notebook computer 4 and the top side wall of the cover shell 2, enabling the temperature of the notebook computer 4 to be quickly reduced.

[0013] Referring to FIG. 3 again, an indicator light 7 is installed in the front side of the cooling rack to indicate the operation status of the fans 3.

[0014] While only one embodiment of the present invention has been shown and described, it will be understood that various modifications and changes could be made thereunto without departing from the spirit and scope of the invention disclosed.
