ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a portable apparatus, and more particularly to a portable computer having a heat dissipating device.
2. Description of the Prior Art
Typical portable computers, or the so-called notebook computers, comprise a parallelepiped housing including a fan device disposed therein for circulating the air or for forcing the air into and out of the housing for heat dissipating purposes. The fan device is normally directed downward to the opening formed in the bottom of the housing. However, the bottom opening of the housing may be blocked when the portable computer is disposed on the legs of the users, such that the microprocessor of the portable computer may be damaged by heat.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional portable computers.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a portable apparatus having a heat dissipating device for facilitating the heat dissipating effect of the portable apparatus.
In accordance with one aspect of the invention, there is provided a portable apparatus comprising a housing including an inclined board formed therein and for defining a cut-off opening therein, the inclined board including at least one aperture formed therein and communicating with the cut-off opening of the housing for preventing the aperture of the inclined board from being blocked, and a fan device secured to the inclined board for circulating air through the aperture of the inclined board and the cut-off opening of the housing.
The housing includes a bottom wall, the inclined board is inclined relative to the bottom wall of the housing. The inclined board includes a spider rib formed therein for forming the aperture therein. The housing includes a side wall having at least one orifice formed therein, and a heat dissipating plate secured in the housing and having a plurality of heat dissipating fins extended therefrom and arranged between the orifice of the side wall and the fan device for allowing the air to flow through the heat dissipating fins. A pad is further secured between the inclined board of the housing and the fan device.
The housing includes a bottom wall and a side wall and an end wall having a corner formed therebetween and having the cut-off opening formed in the corner, the portable apparatus further includes a stand attached to the corner of the housing. The stand includes an L-shaped body having a panel and a projection extended therefrom for engaging with the housing. The stand includes at least one cavity formed therein for allowing the air to flow therethrough.
Further objectives and advantages of the present invention will become apparent from a careful reading of a detailed description provided hereinbelow, with appropriate reference to accompanying drawings.
