In the implementation process of the embodiment, when the whole device is in a standby state or in a small-load operation state, the heat generated by the computer hardware is small, so that the first driving motor 19 can be started, the first driving motor 19 drives the first rotating shaft 15 to rotate through belt transmission, the first rotating shaft 15 drives the screw rod 10 to rotate through the first bevel gear 13 and the second bevel gear 12 which are in meshed connection, the screw rod 10 drives the threaded sleeve 11 to move downwards, so that the driving wheel 21 moves downwards, the cover plate 8 moves downwards under the action of gravity, when the cover plate 8 covers the upper part of the box body 2, the upper opening of the box body 2 is blocked, and the driving wheel 21 is disengaged from the driven wheel 24, the second driving motor 29 is started, the second driving motor 29 drives the second rotating shaft 23 on the front side to rotate through belt transmission, the second rotating shaft 23 on the front side drives the third rotating shaft 34 to rotate through the third bevel gear 31 and the fourth bevel gear 32 which are in meshed connection, the third pivot 34 drives the heat dissipation fan 38 of front side through the fifth bevel gear 35 and the sixth bevel gear 36 that the meshing is connected and rotates, thereby make the inside hot-air of box 2 discharge through the bleeder vent 5 of front side, and box 2 is inside to produce the negative pressure this moment, the negative pressure can make outside cold air can enter into inside box 2 through box 2 itself and the gap between box 2 and the apron 8, thereby preliminary heat dissipation treatment has been realized, the upper portion of whole box 2 is stopped up this moment, and only less heat dissipation fan 38 of front side carries out work, dustproof and the silence effect of computer this moment is best, because the load is less, consequently can carry out stable work under lower radiating efficiency.

When the computer is under a medium load, the operation can be carried out according to the steps, but in the process of descending the cover plate 8, the ejector rod 3 is rotated upwards, and the ejector rod 3 jacks up the cover plate 8, so that a larger gap exists between the cover plate 8 and the box body 2, and more cold air can enter the box body 2 through the gap to carry out heat dissipation treatment, which is better than the heat dissipation effect in the small-load work, but the corresponding mute and dustproof effects are slightly poor.

When the computer is in full load or overload operation, the hardware of the computer generates a large amount of heat, the first driving motor 19 can be started reversely, so that the driving wheel 21 moves upwards, two sides of the driving wheel 21 are in contact with the two driven wheels 24, and the cover plate 8 moves upwards in the process that the driving wheel 21 pushes the driven wheels 24 to move upwards, so that the mounting plate 30 for mounting the computer hardware is completely exposed in the external environment, at the moment, the second driving motor 29 can be started, because the driving wheel 21 enables the two driven wheels 24 on the front side and the rear side to synchronously rotate, so that when the second driving motor 29 works, the heat dissipation fans 38 on the front side and the rear side work, so that air flow from the rear side to the front side is generated through the plurality of heat dissipation fans 38, high-intensity heat dissipation processing is performed on the computer hardware on the mounting plate 30, and the computer reaches the maximum heat dissipation efficiency at the moment, but the effect of dust protection and muting is minimal.

The invention is suitable for a quick heat dissipation device of a computer mainframe, through the up-and-down movement of the driving wheel 21, the device can select different numbers of heat dissipation fans 38 to work under the condition of different heat productivity of the computer, and simultaneously the up-and-down height of the cover plate 8 can be freely adjusted, so that the heat dissipation area and the working number of the fans can be freely adjusted, and the device can furthest ensure the mute and dustproof effect of the computer mainframe on the premise of ensuring the heat dissipation effect.
