DETAILED DESCRIPTION

[0028] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical scheme of the present invention will be clearly and completely described below in conjunction with the drawings in this specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0029] like Figures 1 to 4As shown, in this embodiment, the present invention proposes a server chassis for dust prevention and heat dissipation, including a base 1. A first motor (not shown in the figure due to angle issues) is arranged inside the base 1. The output end of the first motor penetrates through the upper end of the base 1 and is fixed with a turntable 2. A storage rack 11 is arranged on the top of the turntable 2, and electrical components are arranged on the storage rack 11. An embedding groove 3 is formed on the outer periphery of the turntable 2, and an annular outer ring 7 is clamped in the embedding groove 3. An annular inner ring 9 is arranged inside the outer ring 7, and the outer ring 7 and the inner ring 9 are arranged around the storage rack 11; heat dissipation holes 10 are formed on both the outer ring 7 and the inner ring 9, and the heat dissipation holes 10 formed on the outer ring 7 and the inner ring 9 can match each other. Multiple columns of heat dissipation holes 10 are arranged on both the outer ring 7 and the inner ring 9, and the gap between multiple columns of heat dissipation holes 10 is larger than the diameter of each heat dissipation hole 10; the outer ring 7 and the inner ring 9 can rotate relatively; a heat dissipation component and a dust suction mechanism are arranged on the top of the inner ring 9. The heat dissipation component can blow air towards the storage rack 11, and the dust suction mechanism can rotate around the outside of the outer ring 7 to adsorb the dust blown out from the heat dissipation holes 10. Specifically, the outer ring 7 is of a split structure and is composed of two semi-circular ring structures. To adapt to this structure, two embedding grooves 3 are formed on the outer periphery of the turntable 2, and semi-circular ring structures are clamped in both of the two embedding grooves 3 through embedding rings 8, and the ends of the two semi-circular ring structures are in contact with each other to jointly form the outer ring 7. The heat dissipation holes 10 on the outer ring 7 and the heat dissipation holes 10 on the inner ring 9 can drive the base 1 to rotate by the first motor, so that the outer ring 7 rotates to change the overlapping degree of the internal and external heat dissipation holes 10, thereby realizing different heat dissipation effects. And the device adopts heat dissipation from the inside to the outside, which can greatly improve the smoothness of hot air exhaust, effectively dissipate heat from the electrical components installed on the storage rack 11. During the heat dissipation process, the heat dissipation method from the inside to the outside can also blow the dust of the electrical components on the storage rack 11 outwards. And the installation method of the outer ring 7 clamped in the embedding groove 3 through the embedding ring 8 can also improve the convenience of disassembly, assembly and maintenance of the electrical components on the storage rack 11.

[0030] Specifically, as Figure 1 shown, the inner ring 9 and the base 1 are connected through a lifting component. The lifting component includes a lifting disk 6, a connecting disk 5 and an electric telescopic rod 4. The lifting disk 6 is fixed on the top of the inner ring 9, the connecting disk 5 is fixed on the outside of the lifting disk 6, the fixed end of the electric telescopic rod 4 is fixed on the base 1, and the telescopic end of the electric telescopic rod 4 is fixed on the connecting disk 5. By the telescopic movement of the electric telescopic rod 4, the lifting disk 6 can be driven to lift, so that the inner ring 9 fixed at the bottom of the lifting disk 6 moves up and down. The installation method of the inner ring 9 connected through the lifting component and the installation method of the outer ring 7 clamped in the embedding groove 3 through the embedding ring 8 can also improve the convenience of disassembly, assembly and maintenance of the electrical components on the storage rack 11. In this embodiment, two electric telescopic rods 4 are arranged opposite to each other. During the specific implementation process, multiple electric telescopic rods 4 can be arranged according to actual needs.

[0031] As Figure 1 、 Figure 3 、Figure 4 As shown, the heat dissipation component includes a plurality of heat dissipation fans 13. In this embodiment, two heat dissipation fans 13 are provided. The plurality of heat dissipation fans 13 are all arranged on the top of the lifting plate 6, and the air outlets of the plurality of heat dissipation fans 13 all penetrate through the lifting plate 6 and extend towards the inner side of the inner ring 9. The heat dissipation component can use the air flow generated by the two heat dissipation fans 13 to dissipate heat from the electrical components on the inner ring 9's storage rack 11, and blow the dust and heat outwards through the heat dissipation holes 10 together.

[0032] As Figures 1 to 4 shown, the dust suction mechanism includes a driving component, a rotating component, and a dust suction component. The driving component is fixed on the top of the lifting plate 6. One end of the rotating component is connected to the driving component, and the dust suction component is connected to the rotating component. The driving component can drive the rotating component to rotate around the outer ring 7 and adsorb the dust blown out from the heat dissipation holes under the action of the dust suction component. Specifically, among them, the driving component includes a concave plate 14, a second motor 15, and a connecting shaft 16. The concave plate 14 is fixed on the top of the lifting plate 6. An installation space is formed between the concave plate 14 and the lifting plate 6. The second motor 15 is fixed on the bottom surface of the concave plate 14. The driving end of the second motor 15 passes through the concave plate 14 and is fixed with a connecting shaft 16. The other end of the connecting shaft 16 is fixed with a rotating component; the rotating component includes a connecting plate 17 and a connecting piece 20. The connecting plate 17 is arranged parallel to the lifting plate 6. One end of the connecting plate 17 is fixed to the connecting shaft 16, and the other end extends out of the outside of the lifting plate 6 and is fixed with a connecting piece 20. The connecting piece 20 is arranged perpendicular to the lifting plate 6 and is suspended outside the outer ring 7; the dust suction component includes a vacuum cleaner 18 and a connecting pipe 19; the vacuum cleaner 18 is fixed to the top end of the connecting plate 17. A dust suction channel 21 is opened on one side of the connecting piece 20 close to the outer ring 7. One end of the connecting pipe 19 is communicated with the vacuum cleaner 18, and the other end is communicated with the dust suction channel 21. The setting of the dust suction mechanism can drive the connecting shaft 16 and the connecting plate 17 to rotate by the second motor 15 at the bottom of the concave plate 14, and the connecting piece 20 fixed at the end of the connecting plate 17 can be connected to the vacuum cleaner 18 through the connecting pipe 19, so that the suction force generated by the vacuum cleaner 18 adsorbs outwards through the dust suction channel 21 to the outside of the outer ring 7, adsorbing the dust blown out by the electrical components in the storage rack 11 through the heat dissipation component, achieving its dust suction effect, and using the connecting piece 20 that can rotate circumferentially on the outer ring 7 to expand the dust suction range and improve the dust suction effect.

[0033] It should be noted that when the second motor 15 is arranged at the midpoint of the lifting plate 6, the length of the connecting plate 17 should be greater than the radius of the lifting plate 6, so that the end of the connecting plate 17 can extend out of the outside of the lifting plate 6, so that the connecting piece 20 can circularly rotate and adsorb the dust on the entire outside of the outer ring 7.

[0034] At the same time, to further increase the heat dissipation effect, as Figure 3 , Figure 4As shown, a plurality of equally spaced partitions 12 are provided in the rack 11, and a plurality of through holes are provided in the rack 11 and the plurality of partitions 12. The plurality of equally spaced partitions 12 fixed in the rack 11 can increase the number of electrical components installed in the rack 11 and the convenience of classification, and the plurality of through holes provided on the rack 11 and the plurality of partitions 12 can cooperate with the heat dissipation components to improve the internal ventilation and heat dissipation effect and avoid the accumulation of dust. At the same time, a heat conductive layer can be provided on the inner side walls of the outer ring 7 and the inner ring 9, which can also greatly improve the heat dissipation effect inside the entire server chassis.

[0035] A temperature sensor is provided in the inner ring 9. The temperature sensor can detect the temperature in the inner ring in real time, so that the system can adjust the overlap degree of the heat dissipation holes 10 on the outer ring 7 and the inner ring 9 according to the temperature, and change different heat dissipation effects.

[0036] The working principle of the dust-proof and heat-dissipating server chassis is:

[0037] First, according to the result of the temperature sensor detecting the temperature in the inner ring in real time, different heat dissipation effects are adjusted, and the first motor in the base 1 of the device drives the entire turntable 2 and the outer ring 7 clamped in the groove 3 at the top of the turntable 2 to rotate, and the outer ring 7 and the inner ring 9 rotate relative to each other until the heat dissipation holes 10 on the outer ring 7 and the inner ring 9 reach a suitable overlap, and the first motor stops; the heat dissipation fan 13 on the lifting plate 6 continuously blows air to the rack 11 to dissipate the heat of the electrical components on the rack 11, and blows dust and heat out through the multiple heat dissipation holes 10 At the same time, the second motor 15 of the dust collection mechanism is activated, driving the rotation of the connecting shaft 16 and the connecting plate 17. The connecting piece 20 fixed at the end of the connecting plate 17 begins to rotate around the outer side of the outer ring 7. The dust collection channel 21 of the connecting piece 20 is connected to the dust collector 18 through the connecting pipe 19, so that the adsorption force generated by the dust collector 18 is adsorbed to the outer side of the outer ring 7 through the dust collection channel 21, and the dust blown out of the electrical components in the storage rack 11 through the heat dissipation component is adsorbed, thereby achieving the dust collection effect. In addition, the connecting piece 20 that can rotate around the outer ring 7 can expand the dust collection range and improve the dust collection effect.

[0040] 2. First, in the present invention, the first motor in the base 1 of the device can drive the entire turntable 2 to rotate. Multiple heat dissipation holes 10 are provided in the outer ring 7 arranged in the groove 3 at the top of the turntable 2 and in the inner ring 9 arranged inside the outer ring 7. The heat dissipation component at the top of the lifting component is used in cooperation with the multiple heat dissipation holes 10 for heat dissipation. The multiple heat dissipation holes 10 on the outer ring 7 and the multiple heat dissipation holes 10 on the inner ring 9 can change the degree of overlap of the multiple heat dissipation holes 10 by the rotation of the outer ring 9, so as to use the temperature sensor to change different heat dissipation effects.
