Heat dissipation device

Abstract

Embodiments of the present invention provide a heat dissipation device of a notebook computer. The notebook computer is provided with a keyboard. The heat dissipation device includes a heat dissipation component and a heat guiding box, the heat dissipation component is communicated with the heat guiding box, the keyboard is also communicated with the heat guiding box, and the heat guiding box is used to transmit heat in the heat dissipation component to the keyboard.

Description

TECHNICAL FIELD[0001]Embodiments of the present invention relate to a heat dissipation device of a notebook computer.BACKGROUND[0002]FIG. 1 is a schematic view of a conventional heat dissipation device of a notebook computer. Referring to FIG. 1, heat generating elements in the notebook computer 20 mainly includes a graphics card 2 and CPU (central processing unit.) 1. The heat generated in the graphics card 2 and CPU 1 is transmitted to a radiator 4 in a heat dissipation component 21 by a heat guiding pipe 3, and then is blown out of the radiator 4 by a fan 5 in the heat dissipation component 21, so that the heat in the notebook computer 20 is dissipated.[0003]The above mentioned heat dissipation device has the following problems: the heat in the notebook computer 20 is not recycled but is discharged directly, resulting in waste of the heat energy. In addition, for the on-site worker using the notebook computer 20 outdoors, his hands are prone to be frozen stiff or even be frostbit...

AI Technical Summary

Benefits of technology

[0025]The heat dissipation device according to the embodiments of the present invention changes the heat dissipation manner of the conventional notebook computer, and is capable of guiding the heat generated by the graphics card and the CPU to the keyboard, so that the heat generated in the notebook computer can be recycled effectively instead of being discharged directly and the waste of the heat energy can be avoided. Furthermore, the heat dissipation device according to the embodiments of the present invention is capable of taking full advantage of the heat generated by the notebook computer while increasing the heat dissipation, so that the case in which the hands of the on-site worker using the notebook computer outdoors are prone to be frozen stiff or even be frostbit can be avoided.

Problems solved by technology

The above mentioned heat dissipation device has the following problems: the heat in the notebook computer 20 is not recycled but is discharged directly, resulting in waste of the heat energy.

In addition, for the on-site worker using the notebook computer 20 outdoors, his hands are prone to be frozen stiff or even be frostbit when he operates a keyboard 6 at a low ambient temperature.
