Description

The present invention relates to the structure of a dustproof device for a notebook computer, and more particularly to the structure of a dustproof device for a notebook computer that does not require a dust removal hole to be formed in the casing of the notebook computer.

In the prior art, dust removal methods for notebook computers are performed by forming a single dust removal hole on the back surface of the housing of the apparatus, but this hole impairs the aesthetic appearance of the entire housing of the notebook computer. At the same time, the conventional dust removing method makes one dust removing hole in the housing of the fan device, and the dust removing hole greatly affects the execution effect of the fan. Further, the structure becomes complicated, and the place of the back surface where the dust removing hole is formed is too close to the fan, so that dust can be easily sucked again. Most importantly, according to the safety regulations for laptops, if one hole is opened in the laptop's case, foreign matter or fluid will enter the laptop's system and easily damage the entire laptop, so further improvement is required. Met.

As shown in FIG. 1, in one embodiment, the dustproof device for a notebook computer of the present invention is installed in the notebook computer 10. A heat dissipation device 12 is included therein, and the heat dissipation device 12 is installed in the notebook computer 10 to form the dustproof device for the notebook computer described in the present invention. In addition, the heat dissipation device 12 of the present invention is installed on the main processing unit (not shown in FIG. 1) inside the notebook computer 10. The main arithmetic unit is a main arithmetic unit such as one central processing unit (CPU), one memory control unit (MCU) or one graphics processing unit (GPU) that requires heat dissipation in a general laptop computer 10. It is a unit.

As shown in FIGS. 2 and 3, the heat dissipation device 12 is formed by combining one fan set 20 and one heat dissipation fin 30. That is, the heat dissipation device 12 of the present invention includes the fan set 20 and the heat dissipation fins 30. The fan set 20 is for generating heat-dissipating wind power (as shown by the dotted line in FIG. 4) and dust removal wind power (as shown by the dotted line in FIG. 5). The fan set 20 includes one housing 22 and one rotating portion 24. The housing 22 is one upper lid 22A and one lower lid 22B, which are formed by vertically combining both. By providing one opening on one side of the housing 22 and aligning the opening with the radiation direction of the radiation fins 30, it becomes easy to release hot air. As shown in FIG. 3, an opening 23 is provided on one surface of the upper lid 22A of the housing 22 corresponding to the rotating portion 24.

The rotating unit 24 shown in FIG. 3 is mainly one motor 25 combined with one blade device 26. Among them, the motor 25 is located at the center of the rotating part 24, so that the fan set 20 rotates the blade device 26 to provide the rotational power necessary for generating the wind force. By installing the blade device 26 on the outer periphery of the circumference of the motor 25, the blade device 26 rotates with the driving of the motor 25, and produces the required heat radiation wind or dust removal wind force.
As shown in FIG. 3, the fan set 12 of the present invention further includes one air guide device 28. As shown in FIG. 5, the air guide device 28 is installed in the housing 22, and is installed between the rotating portion 24 and one side of the opening of the housing, so that the air guide device 28 and the housing are close to each other (for example, The upper lid 22A) forms one dust removal path 29 between it and one inner wall surface. In practice, the air guide device 28 has a structure of one curved piece, and the structure of the curved piece is provided between one inner wall surface of the adjacent housing 22 (for example, the upper lid 22A). , The dust removal path 29 is formed.

The heat dissipating fins 30 of the present invention are installed in the opening of the housing accommodating the fan set 20, so that heat generated when the main arithmetic unit in the notebook computer 10 is operated can be eliminated by the heat dissipating wind. Heat is conducted to the outside of the notebook computer 10. Further, by providing one cutout opening 32 (as shown in FIG. 2 and FIG. 3) at the location where the heat radiation fin 30 corresponds to the dust removal path 20, when the notebook computer 10 performs the dust removal movement, Dust is blown out of the notebook computer 10 through the cutout opening 32. Here, the notch opening 32 is formed by one notch opening in which one side of the heat dissipation fin 30 is recessed inward. In practice, the notch opening forms a U-shaped or square structure.

As shown in FIGS. 4 and 5, one arc-shaped air blowing path is formed between the outer edge of the rotating portion 24 and the inner wall surface of the housing 22 (for example, the upper lid 22A). As shown by the dotted line in FIG. 4, the air flow path forms a first direction indicated by the dotted arrow in FIG. 4 and a second direction indicated by the dotted arrow in FIG. That is, the above-mentioned first direction is a blowing direction generated by the motor 25 rotating the blade device 26 when the fan set 20 generates the heat radiation wind, that is, a dotted line direction in FIG. 4, mainly in a personal computer. The hot air generated by the arithmetic unit in 1 is blown out of the notebook computer 10 through the radiation fins 30. The second direction is a blowing direction when the fan set 20 generates the dust removal wind force, that is, a dotted line direction in FIG. 5, and the first direction and the second direction are clearly opposite directions. In addition, the dust-removing wind force is blown out through the dust-removing path 29 to the notch opening 32 in the heat radiation fin 30, so that dust can be discharged to the outside of the notebook computer 10.

As shown in FIG. 6, one air outlet 40 is provided on one side of the main body of the notebook computer 10 so as to face the heat radiation fins 30. The installation position of the notebook computer to which the air outlet 40 corresponds can be adjusted according to the form shown in FIG. However, the position of the air outlet 40 shown in FIG. 1 shows only one embodiment, and the air outlet 40 should be installed on any side surface around the notebook computer 10 according to the designer's intention. You can In that case, the installation position of the heat radiation fin 30 is adjusted accordingly, and thus the scope of the embodiment of the present invention is not limited thereto. At the same time, one cover 42 is provided at a location corresponding to the air outlet 40 of the main body of the notebook computer 10 as shown in FIGS. 1 and 6, and the heat radiation fin 30 is provided in correspondence with the inside of the air outlet 40. Set up. Through the component structure of the present invention, the external appearance of a general laptop computer can be maintained even when viewed from the air outlet 40 on the external side. As described above, the hole for discharging dust (that is, the cutout opening 32) is hidden inside the notebook computer, which is an improvement over the conventional technique in which a hole needs to be formed.

To summarize the above, if the heat dissipation fin 30 employed in the present invention is formed with one notch opening 32 recessed and combined with the installation location of the air guide device 28, the original air outlet can be obtained through the design structure of the present invention. Dust can be blown out using one end of the. Therefore, safety regulations will not be affected by making a separate hole in the notebook computer case. Further, dust can be blown out by the structure of the cutout opening 32 at one end of the heat radiation fin 30, and the front end of the heat radiation fin 30 can still maintain a safety regulation structure. As a result, the main body of the laptop computer 10 incorporating the heat dissipation device 12 of the present invention can maintain a general appearance even when viewed from the exterior side, that is, the hole for discharging dust is hidden in the system. Improve the drawbacks of.

The detailed description of the present invention according to the above embodiments does not limit the scope of the present invention. A person who is familiar with the present technology can make appropriate changes and adjustments such as changes in the fixing structure, and the important significance of the present invention is not lost even if such changes and adjustments are made, and are included in the scope of the present invention.
