A pair of vents 15 are provided at the bottom of the main body 1, a second dust-proof net 16 is provided in the vents 15, and a first chute 17, a second chute 18, and a third chute 19 are sequentially provided on the inner side of the fixed frame 7 And the fourth sliding groove 20, the first sliding groove 17 is matched with a first sliding block 21, the first sliding block 21 is fixedly connected with a first mounting plate 22, and the second sliding groove 18 is matched with a second sliding block 23. , The second sliding block 23 is fixedly connected with the second mounting plate 24, the third sliding groove 19 is matched with a third sliding block 25, the third sliding block 25 is fixedly connected with the third mounting plate 26, and the fourth sliding groove 20 is A fourth sliding block 27 is matched, and the fourth sliding block 27 is fixedly connected with a fourth mounting plate 28. The first mounting plate 22, the second mounting plate 24, the third mounting plate 26 and the fourth mounting plate 28 are evenly provided There are several clamping holes 29. The ends of the first mounting plate 22, the second mounting plate 24, the third mounting plate 26 and the fourth mounting plate 28 are all fixedly installed with a clamping block 30, which matches the clamping hole 29 , The front and rear sides of the fixed frame 7 are provided with movable baffles 31, and the edges of the movable baffles 31 are respectively connected to the first mounting plate 22, the second mounting plate 24, the third mounting plate 26 and the fourth mounting plate 28 For fixed connection, a number of strip-shaped heat dissipation holes 32 are uniformly provided on the movable baffle 31, and universal wheels 33 are provided at the bottom four corners of the main box body 1.

[0025] The length of the heat dissipation grille 2 is slightly longer than the length of the U-shaped baffle 31. The strip heat dissipation holes 32 are arranged in an array disk on the movable baffle 31. The first dust-proof net 3 and the second dust-proof net 16 are both made of two layers of yarn The vent 15 is located directly under the second cooling fan 11, and the inner diameter of the vent 15 is larger than the inner diameter of the mounting hole 10. The top of the main box body 1 is provided with a blower 34, and the air outlet of the blower 34 is connected to The mounting cavity 6 is connected, the first cooling fan 5 and the second cooling fan 11 have four blades. The size of the first mounting plate 22, the second mounting plate 24, the third mounting plate 26 and the fourth mounting plate 28 Exactly the same.

[0026] The working principle and use process of the present invention: when in use, by setting the heat dissipation grille 2, the first heat dissipation fan 5, the vent 15 and the second heat dissipation fan 11, the heat dissipation channel and the air flow speed are enlarged, and the heat dissipation efficiency is increased. In order to improve the service life of the main unit, by setting the first damping spring 8, the second damping spring 13 and the third damping spring 14, the stable installation of the fixed frame can be realized if it is shaken during transportation, preventing the internal The computer components are damaged by impact. The first dust-proof net 3, the second dust-proof net 16 and the air drying net 12 can be arranged to dry the air flowing in the installation cavity 6, which has a moisture-proof effect and prevents the main cabinet The internal computer components are damaged by damp. By setting the first mounting plate 22, the second mounting plate 24, the third mounting plate 26, the fourth mounting plate 28 and the movable baffle 31, they are installed in cooperation with the clamping block 30 through the clamping hole 39, It is convenient for the fixed installation and disassembly of the internal components of the computer, convenient and quick to use, and prevents the internal components from shaking. The multiple strip vents 32 on the movable baffle 31 can increase the heat dissipation channel. In addition, the blower 34 can blow fresh cold air Into the installation cavity 6 to accelerate the gas flow, which can greatly improve the heat dissipation efficiency of the main box.

[0027] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, and substitutions can be made to these embodiments without departing from the principle and spirit of the present invention. And variations, the scope of the present invention is defined by the appended claims and their equivalents.
