[0002] A computer is a modern electronic computing machine used for high-speed calculations. It can perform numerical calculations, logical calculations, and has storage and memory functions. The cooling fan device is the main heat dissipation component inside the computer. The fan can blow cold air into the computer and blow out the heat inside the computer.

[0003] For example, the utility model: "A computer cooling fan device", with the announcement number: "CN212322212U", is provided with a noise reduction cover, a silent fan, a radiator and a mounting frame. The noise reduction cover, the silent fan and the radiator are not connected to each other, and any of the three components can be disassembled separately, which makes the operation more convenient. However, during the implementation of the patent, the fan as a whole is installed inside the outer wall through the mounting frame, which makes it inconvenient to separate the fan as a whole from the outer wall, thereby making it inconvenient to take the fan as a whole out of the outer wall for maintenance. In addition, no sound-absorbing structure is provided inside the outer wall, and the noise is only isolated by the noise reduction cover. The noise reduction effect is poor, so that the fan will generate a large noise when it is working and transmit it to the outside of the device. Therefore, the utility model provides a computer cooling fan device for solving the above problems. Utility Model Content

[0023] Furthermore, silencer holes 16 are evenly arranged on the outside of the sound-absorbing hole 7, and sound-absorbing cotton 17 is arranged on the inside of the sound-absorbing hole 16. The noise generated by the fan blades 6 and the motor 10 enters the sound-absorbing hole 7 and is dispersed into multiple groups of silencer holes 16, which can disperse the noise and weaken the noise. The noise is absorbed by the sound-absorbing cotton 17, which can further improve the noise reduction effect of the device.

[0024] Furthermore, the interior of the mounting base plate 9 is evenly provided with first air inlet holes 13 , and the interior of the first air inlet holes 13 is provided with first dustproof nets 12 , and external air enters the interior of the silencer housing 1 through the second air inlet holes 20 and the first air inlet holes 13 .

[0025] Furthermore, a second dustproof net 15 is installed inside the air outlet 8 to prevent external dust from entering the interior of the silencer housing 1 through the air outlet 8 .

[0026] Furthermore, mounting holes 3 are provided at the bottom of both ends of the silencer housing 1, and mounting rods 19 are installed inside the mounting holes 3. The mounting rods 19 are inserted into the mounting holes 14, and the mounting base plate 9 is limited by the mounting rods 19 to prevent the mounting base plate 9 from continuing to move. The mounting base plate 9 can be firmly installed inside the silencer housing 1, and the installation process is completed.

[0027] Furthermore, a connecting plate 2 is installed at one end of the mounting rod 19 away from the silencer housing 1, and a fixing spring 18 is installed at one end of the connecting plate 2 close to the silencer housing 1. The ends of the fixing springs 18 away from the connecting plate 2 are connected to the silencer housing 1.

[0029] Working principle:

[0030] During installation, the installation base plate 9 is pushed into the interior of the muffler housing 1 through the push-pull plate 11, so that the installation base plate 9 is tightly fitted with the positioning block 4;

[0031] At this time, the installation socket 14 on the installation base plate 9 moves to the position facing the installation plug rod 19, and the elastic action of the fixing spring 18 causes it to pull the connecting plate 2, and the connecting plate 2 drives the installation plug rod 19 to move together, so that the installation plug rod 19 can be inserted into the installation socket 14. The installation plug rod 19 limits the installation base plate 9 to prevent the installation base plate 9 from moving further, and the installation base plate 9 can be firmly installed in the sound-absorbing housing 1, completing the installation process;

[0032] When in use, the device is installed inside a computer, the computer provides power to the device, the motor 10 is energized, and the motor 10 drives the fan blades 6 to rotate through the rotating shaft 5, and the fan blades 6 cut the air to generate airflow, so that the external air enters the interior of the silencer housing 1 through the second air inlet 20 and the first air inlet 13, and the air is blown into the computer through the air outlet 8, so as to dissipate heat inside the computer;

[0033] The noise generated by the fan blades 6 and the motor 10 enters the sound-absorbing hole 7 and is dispersed into the multiple groups of silencer holes 16, which can disperse the noise and weaken the noise. The noise can be absorbed by the sound-absorbing cotton 17, which can further improve the noise reduction effect of the device.

[0034] After use, the user can pull the installation rod 19 through the connecting plate 2 to remove the installation rod 19 from the inside of the installation hole 14, so as to release the limit of the installation rod 19 on the installation base plate 9, so that the installation base plate 9 can be moved, and then pull the installation base plate 9 through the push-pull plate 11 to remove the installation base plate 9 from the inside of the silencer housing 1, so that the motor 10 and the fan blades 6 can be directly separated from the silencer housing 1, which is convenient for maintenance of the motor 10 and the fan blades 6.
