[0020] The present invention provides a computer mainframe case that is easy to maintain and has the following beneficial effects:

[0021] 1. A computer mainframe case that is easy to maintain. The sealing door is opened manually by installing a heat dissipation device. Since the sealing doors are provided on both sides of the case, the sealing doors can be opened for inspection and maintenance according to different use environments, so that the case can be maintained more conveniently. When the electronic components inside the case are working, the cooling fan is turned on to draw external air from the air inlet pipe into the bellows. The air entering the bellows is discharged from the heat dissipation pipe into the diversion box, and then enters the two groups of manifolds through the diversion box. Since the two groups of manifolds are respectively located in the power supply cavity and the hard disk cavity, the power supply cavity and the hard disk cavity can be cooled at the same time, so as to achieve the purpose of quickly cooling the case.

[0022] 2. A computer mainframe case which is easy to maintain is provided with an adjusting device and a heat dissipation device. When the temperature in a certain cavity is high, the heat-conducting fins in the cavity transfer the temperature to the heat expansion medium in the hydraulic sleeve. The heat expansion medium expands due to the heat and pushes the sealing piston to move. The sealing piston drives the moving rod to move. The moving rod drives the sealing plate to move, so that the sealing plate slides along the inner wall of the extension tube toward the hydraulic sleeve. With the movement of the sealing plate, the connection point of the extension tube close to the shunt tube is no longer blocked by the sealing plate. The gas in the shunt tube can enter the extension tube and be discharged into the corresponding cavity through the cooling port. When the temperature in a certain cavity gradually decreases, the heat expansion medium in the corresponding hydraulic sleeve contracts, so that the sealing plate can be pushed to block the connection point of the extension tube close to the shunt tube, thereby preventing the cooling port from dispersing the wind force of the cooling ports in other cavities. The area with higher temperature can be heat-dissipated in a centralized manner.

[0023] 3. A computer mainframe case that is easy to maintain has a dustproof device installed. The gas is first filtered by the filter before entering the air inlet pipe, so that dust in the air is filtered out, preventing the gas from bringing dust into the case and affecting the service life of the internal electronic components. When the filter located at the top of the air inlet pipe continues to filter the gas, the drive motor on one side of the bellows can be turned on, and the filter can be rolled up by the rotation of the drive motor. At the same time, the drive motor on the other side of the bellows releases the filter, so that the used part of the filter can be recycled, and then the unused filter can be moved to the top of the air inlet pipe to continue filtering the gas, effectively improving the filtering efficiency.

[0024] 4. The computer mainframe case which is easy to maintain is installed with a brush roller and a filter. When a driving motor drives the filter to be rolled up, the filter passes through an arc-shaped opening during its movement. The brush roller located at the arc-shaped opening can clean the filter passing through. At the same time, the arc-shaped spring can push the positioning bracket to move through its own elastic force. The positioning bracket drives the brush roller to always press against the surface of the filter to clean the rolled-up filter, and the filter can be repeatedly used to filter the gas.

The top of the heat dissipation device 6 passes through the top of the box body 1 and is fixedly connected to the top of the box body 1. The bottom of the dustproof device 7 is fixedly connected to the top of the box body 1.

[0040] Wherein, the heat dissipation device 6 comprises:

[0041] A bellows 61, the interior of the bellows 61 is connected to an air inlet pipe 62, the inner wall of the air inlet pipe 62 is fixedly connected to a support frame 63, and the top of the support frame 63 is fixedly connected to a cooling fan 64;

[0042] The shunt box 65 has heat dissipation pipes 66 on both sides thereof, and the top and bottom of the shunt box 65 are both connected to shunt pipes 67 .

[0043] There are multiple groups of air inlet pipes 62, which are evenly distributed on the top of the bellows 61. The top of the air inlet pipes 62 passes through the top of the bellows 61. There are multiple groups of heat dissipation pipes 66. One end of the heat dissipation pipes 66 away from the diverter box 65 is connected to the interior of the bellows 61. The bottom of the diverter box 65 passes through one side of the partition 5 and is fixedly connected to one side of the partition 5. The top of the bellows 61 passes through the top of the box body 1 and is fixedly connected to the top of the box body 1.

[0044] The heat dissipation device 6 also includes an adjusting device 68 . One end of the shunt pipe 67 away from the shunt box 65 is connected to one end of the adjusting device 68 . There are two groups of adjusting devices 68 , which are respectively located at the top and bottom of the partition 5 .

[0045] The adjusting device 68 includes an extension tube 681, one end of which is fixedly connected to a hydraulic sleeve 682, the inner wall of the hydraulic sleeve 682 is slidably connected to a sealing piston 683, one side of the sealing piston 683 is fixedly connected to a moving rod 684, the end of the moving rod 684 away from the sealing piston 683 is fixedly connected to a sealing plate 685, one side of the hydraulic sleeve 682 is penetrated and fixedly connected to a heat-conducting fin 686, and the outer side of the extension tube 681 is symmetrically provided with a cooling port 687.

[0046] One end of the extension tube 681 away from the hydraulic sleeve 682 is connected to one end of the diversion tube 67, and the end of the moving rod 684 close to the sealing plate 685 passes through the bottom of the hydraulic sleeve 682 and is slidably connected to the bottom of the hydraulic sleeve 682 through the sealing sleeve. The sealing plate 685 is located inside the extension tube 681 and is slidably connected to the inner wall of the extension tube 681.

[0047] The portion of the hydraulic sleeve 682 located on one side of the sealing piston 683 is filled with a heat expansion medium. Multiple groups of heat-conducting fins 686 are provided, and the multiple groups of heat-conducting fins 686 are evenly distributed on the outside of the hydraulic sleeve 682 .

[0048] During use, the hardware is manually installed into the power cavity and hard disk cavity inside the case 1. When the case 1 needs to be inspected and maintained, the sealed door 4 can be manually opened. Since the sealed doors 4 are provided on both sides of the case 1, the sealed doors 4 can be opened for inspection and maintenance according to different usage environments, so that the case 1 can be maintained more conveniently. When the electronic devices inside the case 1 are working, the cooling fan 64 is turned on to draw the external air into the bellows 61 from the air inlet pipe 62. The gas entering the bellows 61 is discharged from the heat dissipation pipe 66 into the diversion box 65, and then enters the two groups of manifolds 67 through the diversion box 65. Since the two groups of manifolds 67 are respectively located in the power cavity and the hard disk cavity, the power cavity and the hard disk cavity can be cooled at the same time, so as to achieve the purpose of quickly cooling the case 1.

[0049] The heat conducting fins 686 located in the power cavity and the hard disk cavity transfer the temperature inside the cavity to the hydraulic sleeve 682 respectively. When the temperature in a cavity is high, the heat conducting fins 686 in the cavity transfer the temperature to the heat expansion medium in the hydraulic sleeve 682. After the heat expansion medium expands due to the heat, it pushes the sealing piston 683 to move. The sealing piston 683 drives the moving rod 684 to move. The moving rod 684 drives the sealing plate 685 to move, so that the sealing plate 685 slides along the inner wall of the extension tube 681 toward the hydraulic sleeve 682. As the sealing plate 685 moves, the extension tube 681 moves. The connection point of the extension pipe 681 near the shunt pipe 67 is no longer blocked by the sealing plate 685, and the gas in the shunt pipe 67 can enter the extension pipe 681 and be discharged into the corresponding cavity through the cooling port 687. When the temperature in a certain cavity gradually decreases, the thermal expansion medium inside the corresponding hydraulic sleeve 682 shrinks, which can push the sealing plate 685 to block the connection point of the extension pipe 681 near the shunt pipe 67, thereby preventing the cooling port 687 from venting air and dispersing the wind force of the cooling ports 687 in other cavities, thereby centrally dissipating heat in areas with higher temperatures.

[0050] For the second embodiment, please refer to Figure 1-Figure 8 The present invention provides a technical solution: on the basis of the first embodiment, the dustproof device 7 includes a fixed shell 71, the outer side of the fixed shell 71 is fixedly connected to a driving motor 72, the fixed shell 71 and the driving motor 72 are both provided with two groups and symmetrically distributed on both sides of the bellows 61, the bottom of the fixed shell 71 is fixedly connected to the top of the box body 1, a filter screen 73 is wound around the output end of the driving motor 72, and the two ends of the filter screen 73 are respectively wound around the output ends of the driving motor 72 on both sides of the bellows 61, and an arc-shaped opening 74 adapted to the filter screen 73 is opened on one side of the fixed shell 71.

[0051] The output end of the driving motor 72 passes through the fixed shell 71 and extends to the inside of the fixed shell 71 , and the bottom of the filter screen 73 extends to the top of the air inlet pipe 62 .

[0052] The inner wall of the arc-shaped opening 74 is fixedly connected with a limit plate 75, and two groups of limit plates 75 are provided. The two groups of limit plates 75 are symmetrically distributed on both sides of the filter screen 73. The side of the limit plate 75 close to the filter screen 73 is fixedly connected with an arc-shaped bracket 76, and the side of the arc-shaped bracket 76 away from the limit plate 75 is fixedly connected with a positioning bracket 78 through an arc spring 77. One side of the positioning bracket 78 is fixedly connected with a brush roller 79. Two groups of positioning brackets 78 are provided and are symmetrically distributed at both ends of the brush roller 79, and bristles are evenly installed on the outside of the brush roller 79.

[0053] During use, the gas is first filtered by the filter 73 before entering the air inlet pipe 62, so that the dust in the air is filtered out, preventing the gas from bringing dust into the box body 1 and affecting the service life of the internal electronic components. When the filter 73 located at the top of the air inlet pipe 62 continues to filter the gas, the drive motor 72 on one side of the bellows 61 can be turned on, and the filter 73 can be rolled up by the rotation of the drive motor 72. At the same time, the drive motor 72 on the other side of the bellows 61 releases the filter 73, so that the used part of the filter 73 can be recycled, and then the unused filter 73 can be moved to the top of the air inlet pipe 62 to continue filtering the gas, effectively improving the filtration efficiency.

[0054] When the driving motor 72 drives the filter screen 73 to be rolled up, the filter screen 73 passes through the arc-shaped opening 74 during its movement, and the brush roller 79 located at the arc-shaped opening 74 can clean the filter screen 73 passing through. At the same time, the arc-shaped spring 77 can push the positioning bracket 78 to move through its own elastic force, and the positioning bracket 78 drives the brush roller 79 to always press against the surface of the filter screen 73 to clean the rolled up filter screen 73, so that the filter screen 73 can be repeatedly used to filter the gas.

[0055] Working principle: The hardware is manually installed into the power cavity and hard disk cavity inside the box body 1. When the box body 1 needs to be inspected and maintained, the sealed door 4 can be opened manually. Since the sealed doors 4 are provided on both sides of the box body 1, the sealed doors 4 can be opened for inspection and maintenance according to different usage environments, so that the box body 1 can be maintained more conveniently. When the electronic devices inside the box body 1 are working, the cooling fan 64 is turned on to draw the external air into the bellows 61 from the air inlet pipe 62. The air entering the bellows 61 is discharged into the shunt box 65 from the heat dissipation pipe 66, and then enters the two groups of manifolds 67 through the shunt box 65. Since the two groups of manifolds 67 are respectively located in the power cavity and the hard disk cavity, the power cavity and the hard disk cavity can be inspected and maintained at the same time. Heat dissipation: The heat-conducting fins 686 located in the power cavity and the hard disk cavity transfer the temperature inside the cavity to the hydraulic sleeve 682 respectively. When the temperature in a cavity is high, the heat-conducting fins 686 in the cavity transfer the temperature to the heat expansion medium in the hydraulic sleeve 682. After the heat expansion medium is heated, it pushes the sealing piston 683 to move, and the sealing piston 683 drives the moving rod 684 to move. The moving rod 684 drives the sealing plate 685 to move, so that the sealing plate 685 slides along the inner wall of the extension tube 681 toward the hydraulic sleeve 682. With the movement of the sealing plate 685, the connection point of the extension tube 681 close to the shunt tube 67 is no longer blocked by the sealing plate 685, and the gas in the shunt tube 67 can enter the extension tube 681. The gas is discharged into the corresponding cavity through the cooling port 687. When the temperature in a cavity gradually decreases, the heat expansion medium inside the corresponding hydraulic sleeve 682 contracts, and the sealing plate 685 is pushed to block the connection between the extension tube 681 and the shunt tube 67, so as to prevent the cooling port 687 from blowing out and dispersing the wind force of the cooling ports 687 in other cavities. The gas can be concentratedly cooled in the area with higher temperature. Before entering the air inlet pipe 62, the gas is first filtered by the filter 73 to filter out the dust in the air, so as to prevent the gas from bringing dust into the box body 1 and thus affecting the service life of the internal electronic components. After the filter 73 at the top of the air inlet pipe 62 continues to filter the gas, the side of the bellows 61 can be opened. The drive motor 72 reels the filter 73 by rotating the drive motor 72. At the same time, the drive motor 72 on the other side of the bellows 61 releases the filter 73, so that the used part of the filter 73 can be recovered, and the unused filter 73 can be moved to the top of the air inlet pipe 62 to continue filtering the gas. When the drive motor 72 drives the filter 73 to reel up, the filter 73 passes through the arc-shaped opening 74 during its movement, and the brush roller 79 located at the arc-shaped opening 74 can clean the passing filter 73. At the same time, the arc spring 77 can push the positioning bracket 78 to move through its own elastic force, and the positioning bracket 78 drives the brush roller 79 to always press against the surface of the filter 73 to clean the reeled filter 73.
