Description

Technical Field

[0001] The present invention belongs to the technical field of computer chassis, and specifically refers to a computer combined chassis with the functions of cooling and noise reduction. Background Art

[0002] With the update of computer software and hardware performance, when running large software (such as 3D modeling, video editing), games or opening multiple programs simultaneously, the computing volume of the processor surges, and heat is generated when current passes through transistors. In addition, frictional heat is generated when the traditional mechanical hard disk rotates at high speed; solid-state drives also generate heat during a large amount of data transmission; chaotic wiring inside the chassis or narrow internal space of the chassis hinders air flow, which is also the reason for the increase in chassis temperature and noise.

[0003] There is a patent document with the application number: CN202421327985.4 and the name: A computer chassis heat dissipation device with a water cooling function, which adopts the technical solution of "opening a plurality of installation slots on one side of the mounting plate, and a semiconductor refrigeration plate is connected inside the installation slots", to achieve the effect of "rapidly cooling the inside of the chassis through cold air, solving the disadvantages of air cooling, and combining refrigeration to improve the quality and efficiency of heat dissipation and cooling". This technical means does not consider the situation where water is generated after the cold air emitted by the semiconductor refrigeration plate contacts the hot air inside the chassis. The condensation of liquid water inside the chassis will cause short circuits of the circuit board and damage to the chassis. At the same time, the structure of the chassis has not changed, and the internal space of the chassis is still narrow, and the noise problem of the chassis cannot be solved. Summary of the Invention

[0004] In view of the above situation, in order to avoid short circuits of equipment caused by condensed liquid water inside the chassis and at the same time reduce the noise generated by the chassis, the present invention provides a computer combined chassis with the functions of cooling and noise reduction. While ensuring refrigeration and cooling of the inside of the chassis, the structure of the chassis is changed to expand the internal volume of the chassis, reduce the noise of air cooling, and at the same time discharge the water generated during the refrigeration process to reduce the risk of short circuits in the chassis.

The limit protrusion one can only deflect in one direction in the protrusion groove one. The driven gear one is concentric with the rotating limit collar one. The transmission gear two and the driven gear one are fixedly connected and coaxially connected through a bracket.

[0010] Furthermore, the acceleration cleaning device includes a planetary gear ring, planetary gears, a sun gear, a planetary bracket, a transmission gear set, and a cleaning roller shaft.

[0016] A computer combined chassis with the functions of cooling and noise reduction provided by this solution has the following beneficial effects: (1) The cooperation of the rotating limiting collar one and the limiting protrusion one in the bottom cleaning and dehumidifying device enables the rotating limiting collar one to only rotate in one direction under the drive of the driven gear one, ensuring that the cleaning roller shaft only has the effect of cleaning and absorbing water when the arc-shaped dust-proof plate enters the chassis. Similarly, the rotating limiting collar two also only has the effect of rotating in one direction, causing the top scraping plate to only displace when the arc-shaped dust-proof plate moves out of the chassis. (2) Through the meshing connection relationship between the planetary gear and the fixed gear, the cleaning roller shaft is driven to rotate, and the rotation speed of the cleaning roller shaft is accelerated, increasing the centrifugal force of the strip-shaped protrusions, enabling them to fully contact the bottom wall of the arc-shaped dust-proof plate and thus absorb the moisture on the arc-shaped dust-proof plate.

[0031] The top wall and the bottom wall of the fan assembly 7 are configured as arc-shaped structures, and a dust-proof filter screen is provided on the rear wall of the air supply assembly. The fan assembly 7 is snap-fitted and rotatably arranged on the chassis housing 1.

[0032] The semiconductor refrigeration chip 10 uses the model TES1-12706 SR.

[0033] During specific use, when the computer is running and the fan can no longer meet the cooling requirements, the driving cylinder 8 extends to adjust the deflection direction of the combined connecting plate 9, making the internal space of the chassis housing 1 larger, increasing the distance between the fan and the obstacle, reducing the wind resistance and lowering the noise. When the combined connecting plate 9 is opened, the arc-shaped dust-proof plate 11 and the side dust-proof plate 12 are still connected to the chassis housing 1, ensuring that the electronic devices inside the chassis are not largely exposed to the external environment. As the angle of the combined connecting plate 9 changes, the deflection direction of the fan assembly 7 is adjusted to blow the hot air inside the chassis towards the direction where the semiconductor refrigeration chip 10 is located. After the semiconductor refrigeration chip 10 is powered on and operates, the hot air inside the chassis contacts the cold air generated on the surface of the semiconductor refrigeration chip 10 to produce water vapor condensation on the surface of the combined connecting plate 9. The liquid water flows along the combined connecting plate 9 to the lower arc-shaped dust-proof plate 11 and then is discharged from the chassis through the small holes of the arc-shaped dust-proof plate 11. After the temperature inside the chassis decreases, the combined connecting plate 9 is closed, the driving cylinder 8 contracts, the arc-shaped dust-proof plate 11 slides, the rack at the bottom of the arc-shaped dust-proof plate 11 meshes with the first driving gear 17, the first driving gear 17 rotates, and through meshing transmission to the second transmission gear 18, the power of the second transmission gear 18 is then transmitted to the first driven gear 22 through the bracket. The first driven gear 22 rotates and collides with the first limiting protrusion 20. The first limiting protrusion 20 drives the first rotating limiting collar 19 to rotate. The first rotating limiting collar 19 drives the planetary gear 24 to rotate through the planetary bracket 26. Under the limiting action of the planetary gear ring 23, the planetary gear 24 rotates on its own axis on the planetary bracket 26. The fixed star gear 25 rotates due to the meshing connection with the planetary gear 24. After being transmitted by the transmission gear set 27, the cleaning roller shaft 28 obtains centrifugal force and rotates rapidly, making the strip-shaped protrusions 29 on the surface of the cleaning roller shaft 28 obtain centrifugal force. The strip-shaped protrusions 29 contact the bottom wall of the arc-shaped dust-proof plate 11 and absorb the water on the arc-shaped dust-proof plate 11; During the rotation of the first driving gear 17, the second driven gear 33 synchronously obtains the power of the second transmission gear 18. The second driven gear 33 presses the second limiting protrusion 35. The second limiting protrusion 35 rotates inward into the second protrusion slot 36 under the pressure. The second limiting protrusion 35 cannot drive the second rotating limiting collar 34 to rotate. The polarization wheel 37 is fixedly connected to the second rotating limiting collar 34. The polarization wheel 37 has no displacement. The sliding limiting rod 39 is always supported by the polarization wheel 37. The top scraping plate 38 closely adheres to the top wall of the arc-shaped dust-proof plate 11. When the arc-shaped dust-proof plate 11 moves, the water on the upper wall of the arc-shaped dust-proof plate 11 is removed; When the arc-shaped dust-proof plate 11 moves out of the chassis and the first driving gear 17 rotates and the first driven gear 22 rotates, the first limiting protrusion 20 deflects and hides into the first protrusion slot 21. The first rotating limiting collar 19 does not rotate. The cleaning roller shaft 28 has no centrifugal force. However, the second rotating limiting collar 34 rotates. The second limiting protrusion 35 presses the rotating limiting collar. The second rotating limiting collar 34 rotates. The polarization wheel 37 obtains power. The sliding limiting rod 39 is pushed by the arc-shaped side wall of the polarization wheel 37, causing the top scraping plate 38 to slowly rise until the arc-shaped dust-proof plate 11 completely moves to the set position. The sliding limiting rod 39 drops to the section plane of the polarization wheel 37, making the top scraping plate 38 instantly fit on the upper wall of the arc-shaped dust-proof plate 11; After the cleaning roller shaft 28 gets wet, the second arc-shaped limiting plate 32 approaches the cleaning roller shaft 28 under the action of the cylinder and cooperates with the first arc-shaped limiting plate 31. The first arc-shaped limiting plate 31 and the second arc-shaped limiting plate 32 cooperate to squeeze the cleaning roller shaft 28, reducing the water content on the cleaning roller shaft 28. The water is discharged from the chassis, reducing the risk of equipment short circuit caused by excessive water inside the chassis.
