Description

Technical Field

[0001] The invention relates to a computer case, in particular to a heat dissipation and dust removal computer case. Background Art

[0002] As is known, with the continuous improvement of living standards, people's demand for computers is also increasing. Most of the computers currently used are divided into two parts: a chassis and a display. Most of the computer chassis are simple box structures, and the necessary circuit components of the computer are installed in the computer chassis. During the use of the computer, in order to ensure the normal operation of the computer, a heat dissipation structure must be installed in the computer chassis. Usually, a heat dissipation fan is installed in the computer chassis for heat dissipation. During the heat dissipation process, the heat dissipation fan can only blow air to dissipate heat to local components in the computer chassis, and the ventilation holes on the surface of the chassis are not aligned with the heat dissipation fan, resulting in an unsatisfactory heat dissipation effect inside the chassis. In addition, during the use of the computer, the circuit components inside the computer chassis will generate a certain amount of static electricity after the power is turned on, which will adsorb dust in the air to the surface of the circuit components. The dust adsorbed on the circuit components cannot be effectively blown away by using only the heat dissipation fan inside the chassis. When there is too much dust adsorbed on the circuit components, it will not only affect the heat dissipation effect of the circuit components, but also cause a short circuit in the chassis internal circuit in severe cases, affecting the normal use of the computer. Summary of the invention

[0003] In order to overcome the deficiencies in the background technology, the present invention discloses a heat dissipation and dust removal computer case. Through the present invention, not only can the inside of the computer case be effectively dust-proof and heat-dissipating, but also the dust adsorbed on the circuit components can be blown away and cleaned, thereby providing strong support for the normal use of the computer and greatly extending the service life of the circuit components in the computer case.

The L-shaped blowing rod 12 is composed of a vertical rod 18, a horizontal rod 19 and an air nozzle 20. The horizontal rod 19 is provided at the lower end of the vertical rod 18, and the air nozzle 20 is provided at the other end of the horizontal rod 19. The upper end of the vertical rod 18 of the L-shaped blowing rod 12 is fixedly connected to the through hole 4 on one side of the upper surface of the chassis 5. The pressing rod 3 is connected to the L-shaped blowing rod 12. The vertical rods 18 are clearance-matched, and the lengths of the vertical rods 18 of the several L-shaped blowing rods 12 are all different. The several L-shaped blowing rods 12 use vertical rods 18 of different lengths to make the air nozzles 20 correspond to different circuit components inside the chassis 5 respectively. Neck-shrinking inclined plates 13 are respectively provided on both side surfaces of the lower end of the interior of the chassis 5, and several through holes 14 are respectively provided on the neck-shrinking inclined plates 13 on the two side surfaces. Expanding inclined plates 16 are respectively provided at the lower ends of the neck-shrinking inclined plates 13 on the two side surfaces. A ventilation cavity 15 is formed between the outer surfaces of the neck-shrinking inclined plates 13 and the expanding inclined plates 16 and the side walls of the chassis 5. Ventilation holes 17 corresponding to the ventilation cavity 5 are respectively provided on the two side walls of the chassis 5.

[0021] To implement the heat dissipation and dust removal computer case described in the present invention, before using the computer, by pressing the push-pull rod 1 at the upper end of the case 5, the pressing rod 2 passes through the through hole 4 to press and blow the L-shaped blowing rod 12, and the air jet nozzle 20 at the front end of the L-shaped blowing rod 12 can be used to blow air to each circuit component inside the case 5.

During the use of the computer, the heat dissipation fan 9 in the case 5 performs heat dissipation work, blowing air from the upper end of the case 5 to the lower end of the case 5. When the air passes through the necking inclined plate 13, the air passes through the through hole 14 on the necking inclined plate 13 and flows into the ventilation cavity 15, and flows out from the ventilation holes 17 on both sides. 13 has a certain inclination angle, which causes the through hole 14 to also be an inclined through hole. The dust in the air will not fall directly into the ventilation cavity 15, but will be blown through the surface of the necking inclined plate 13 to the dust collecting groove 7 in the enlarged diameter inclined plate 16 at the lower end of the necking inclined plate 5; in the continuous heat dissipation process, due to the small diameter of the upper end of the enlarged diameter inclined plate 16, it is difficult for the heat dissipation fan 9 to blow the dust in the dust collecting groove 7 back to the inside of the chassis 5; people can regularly pull the dust collecting groove 7 out of the socket 6 on the front side panel of the chassis 5 to clean the dust; the present invention can not only effectively perform dust-proof and heat dissipation treatment on the inside of the computer chassis, but also can blow and clean the dust adsorbed on the circuit components, providing strong support for the normal use of the computer and greatly extending the service life of the circuit components in the computer chassis.

[0022] Based on the above-mentioned ideal embodiments of the present invention, those skilled in the art can make various changes and modifications without departing from the technical concept of the present invention through the above-mentioned description. The technical scope of the present invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.

When the air passes through the neck-reduced inclined plate, the air flows through the through holes on the neck-reduced inclined plate into the ventilation cavity and flows out from the ventilation holes on both sides. Since the neck-reduced inclined plate has a certain inclination angle, the through holes are also inclined through holes. Dust in the air will not fall directly into the ventilation cavity, but will be blown through the surface of the neck-reduced inclined plate to the dust collection groove in the enlarged inclined plate at the lower end of the neck-reduced inclined plate. During the continuous heat dissipation process, due to the small diameter of the upper port of the expansion ramp, it is difficult for the cooling fan to blow the dust in the dust collection slot back into the chassis through continuous blowing. The dust collection slot is regularly pulled out from the socket on the front panel of the chassis to clean the dust.
