When the cross bar 1502 rotates counterclockwise, since connecting plates 1505 are fixedly installed on the outer walls of both the upper guide ring 1504 and the lower support ring 1503, a through guiding groove is opened on the side wall of the upper guide ring 1504, and the lower part of the guiding groove of the upper guide ring 1504 is inclined.

The side wall of the vertical attachment plate 22 is slidably fitted and inserted into the inner wall of the loading plate 1, and the top of the vertical attachment plate 22 is fixedly connected to the bottom surface of the moving frame 14, so that the vertical attachment plate 22 can drive the carding frame 25 to move upward through the limiting frame 24, so that the top of the carding frame 25 can be flush with the top of the heat dissipation fin plate 9.

A convex disc is arranged on the side wall of the thrust ring 8, and the thrust ring 8 is rotatably embedded in the inner wall of the air intake filter pipe 6, so that the convex disc on the thrust ring 8 can push the limiting frame 24 and the carding frame 25 to move.

[0022] An electronic device for protecting and installing the above high-efficiency heat dissipation graphics card structure, including: A bottom plate 2, with a housing 4 fixedly connected to the four sides of the bottom plate 2. The upper surface of the bottom plate 2 is fixedly connected to a circuit board 3 by screws, and the connector components on the circuit board 3 are all fitted and penetrated between the bottom plate 2 and the housing 4. And there is a gap forming a air duct between the circuit board 3 and the bottom surface of the heat dissipation fin plate 9. The loading plate 1 in the high-efficiency heat dissipation graphics card structure is fixed on the bottom plate 2 by glue. The heat dissipation fin plate 9 in the high-efficiency heat dissipation graphics card structure is attached to the processing chip of the circuit board 3 through a bottom contact copper sheet.

[0023] Working principle: When using the high-efficiency heat dissipation graphics card structure and the electronic device, first refer to Figures 1 - 13 , the device controls the first fan 7 and the second fan 21 to start. Under the action of the first fan 7, the outside air will enter between the bottom surface of the loading plate 1 and the top of the bottom plate 2 through the air intake filter pipe 6. Then the air flow will pass through the gap between the bottom surface of the heat dissipation fin plate 9 and the circuit board 3 to carry part of the heat. At the same time, the heat generated by the chip on the circuit board 3 will be conducted to the fins on the top of the heat dissipation fin plate 9. Then the air flow will pass through the bottom of the heat dissipation fin plate 9. When the air flow passes through the fins on the top of the heat dissipation fin plate 9, it will further carry heat. At the same time, the second fan 21 will continuously extract the hot air that has passed through the fins in the device; When it is necessary to clean the dust on the fins of the heat dissipation fin plate 9, the device controls the second fan 21 to rotate counterclockwise in reverse. The second fan 21 will drive the cross bar 1502 to rotate synchronously through the exhaust sleeve 20. Since the tension spring 18 will apply an upward pulling force on the mounting ring 17, the mounting ring 17 will apply a pulling force on the rotating sleeve 1501 through the connecting ring 16, so that when the rotating sleeve 1501 rotates counterclockwise, the cross bar 1502 can enter the inclined groove at the lower part of the upper guide ring 1504. At this time, the cross bar 1502 will first drive the upper guide ring 1504 to rotate, and the upper guide ring 1504 will drive the connecting plate 1505 to rotate synchronously, so that the connecting plate 1505 rotates along the arc groove on the loading plate 1. The connecting plate 1505 drives the closing plate 1508 to rotate through the rotating ring 1506 and the transmission rack 1507. The four closing plates 1508 will rotate synchronously, and the four closing plates 1508 are used to completely close the air duct at the top of the loading plate 1 to prevent dust from entering the external chassis. After the upper guide ring 1504 cannot move, the cross bar 1502 will continue to move upward along the inclined groove on the upper guide ring 1504. At this time, the cross bar 1502 will drive the rotating sleeve 1501 and the moving frame 14 to move upward synchronously. During this process, the moving frame 14 will drive the tension plate 13 to move upward, and the inclined groove on the tension plate 13 will first push the stress frame 12 to move horizontally. The stress frame 12 pushes the collection box 10 to move. The collection box 10 drives the limit rod 11 to slide on the loading plate 1. The collection box 10 will fit against the end of the heat dissipation fin plate 9, so as to block the air duct on the lower side of the heat dissipation fin plate 9. At the same time, the port at the top of the collection box 10 will open. At the same time, the upward moving moving frame 14 will drive the limit frame 24 and the combing frame 25 to move upward synchronously through the vertical attachment plate 22 until the branch plate of the combing frame 25 is flush with the top of the fins of the heat dissipation fin plate 9, so as to clean the dust and sundries on the heat dissipation fin plate 9. At this time, the bottom surface of the combing frame 25 will just be above the port of the collection box 10. At this time, the limit frame 24 and the thrust ring 8 will be at the same height. When the device controls the first fan 7 to rotate, the first fan 7 will push the limit frame 24 to move through the convex disc on the thrust ring 8, and the return spring 23 will drive the limit frame 24 to move back, so that the limit frame 24 can drive the combing frame 25 to move horizontally back and forth. At this time, the combing frame 25 can send the cleaned dust and sundries into the collection box 10. After the cleaning is completed, the second fan 21 rotates clockwise forward for the reset operation.
