Description

Technical Field

[0001] The utility model relates to the technical field of computers, in particular to a fixing structure of a cooling fan for a CPU computer. Background Art

[0002] With the development of electronic devices, especially the advancement of computer technology, CPU performance is becoming more and more powerful, and the heat generated is also increasing. In order to maintain the normal operating temperature of the CPU and prevent overheating, the cooling fan has become one of the necessary components. The cooling fan can quickly take away the hot air and introduce cold air to reduce the CPU temperature.

[0003] However, it is found that the existing cooling fan installation method is to fix the fan with screws or clips; when the fan increases its speed, it will vibrate and collide with the host back panel to produce high noise, which affects the user experience and even causes damage to other components. Utility Model Content

[0004] In order to solve the problems of the prior art, the utility model provides a fixing structure of a cooling fan for a CPU computer, aiming to solve the problems of vibration and noise generated by the installation of the cooling fan.

[0005] The solution adopted by the utility model to solve its technical problems is: a fixing structure of a cooling fan for a CPU computer, comprising a mounting base and an air balancing cover arranged on the mounting base, a first mounting groove and a second mounting groove for accommodating the cooling fan are respectively arranged between the mounting base and the air balancing cover, shockproof corner pads are arranged at the corner ends of the first mounting groove and the second mounting groove, a buckle assembly that is easily detachably connected to the mounting base is arranged on the air balancing cover, and a plurality of noise-reducing air balancing sheets for reducing wind noise are arranged on the upper row of the air balancing cover.

[0006] By adopting the above technical solution, the cooling fan is installed in two installation slots and the air balancing cover and the installation base are clamped together and then shock-proof corner pads are provided at the corner ends to prevent the fan from shaking and colliding with the fixed structure to generate noise during operation. Air balancing blades are installed at the fan outlet to reduce the noise generated by the airflow. The snap-on assembly makes it easy to disassemble the air balancing cover and take out the fan for maintenance.

[0007] Furthermore, the noise reduction and air balancing blades are in the shape of wing blades that gradually become thinner from the middle to both sides.

[0008] By adopting the above technical solutions, the airflow is smoothed and the turbulence and noise generated by the fan are reduced.

[0009] Furthermore, the buckle assembly extends vertically on both sides of the wind equalizing hood, and the buckle assembly includes a buckle portion and a pressing end integrated with the buckle portion for controlling the buckle portion to perform elastic pressing displacement, and a buckle hole adapted for the buckle portion is provided on the mounting base.

[0010] Furthermore, the buckle portion is provided with a fixing piece fixed to the buckle hole.

[0011] By adopting the above technical solution, the snap-fitting part is snapped into the snap-fitting holes on both sides of the mounting base to form a fixation to prevent the internal fan from shaking and generating noise during operation; when disassembly is required, the pressing end is pressed to make the fixing part on the snap-fitting part elastically displaced, so that the fixation can be cancelled and the internal cooling fan can be taken out for maintenance.

[0012] Furthermore, the anti-vibration corner pads are rubber pads.

[0013] By adopting the above technical solution, the rubber corner pad has good elasticity and softness, can absorb the vibration and impact force generated when the fan is running, prevent it from colliding with the installation base to generate noise, and provide a more stable and quiet working environment.

[0014] Furthermore, a dustproof net is provided at the bottom of the first mounting groove to prevent dust from entering.

[0015] By adopting the above technical solution, dust and impurities in the air can be effectively filtered, which can reduce the dust from entering the fan and the inside of the chassis and reduce the failure rate.

[0016] Furthermore, a mounting portion is extended from the mounting base toward the peripheral side of the first mounting groove, and the corner ends of the mounting portion are all provided with fixing countersunk holes for fixing to the chassis back plate.

[0017] By adopting the above technical solution, the mounting base is fixed on the chassis by fixing the mounting bolts in the countersunk holes, so that the fan can be placed in the base when it is installed and fixed, and there is no need to install the fan with bolts.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. The utility model fixes the fan by arranging an air distribution cover and a mounting base, and then provides rubber shockproof corner pads at the corner ends to prevent the fan from shaking and colliding with the fixed structure to generate noise when running.

[0020] 2. The utility model can smooth the airflow and reduce the turbulence and noise generated by the fan by installing noise-reducing and air-distributing blades at the fan outlet that are gradually thinned toward both sides.

[0032] like Figures 1 to 5 As shown, a fixing structure of a cooling fan 9 for a CPU computer is intended to provide a fixing structure that is convenient for installing the cooling fan 9 and prevents it from generating vibration and noise; wherein the present embodiment includes a mounting base 1 and an air balancing cover 2 arranged on the mounting base 1, a first mounting groove 3 and a second mounting groove 4 for accommodating the cooling fan 9 are respectively provided between the mounting base 1 and the air balancing cover 2, shockproof corner pads 5 are provided at the corner ends of the first mounting groove 3 and the second mounting groove 4, and a snap-on assembly 6 that is easily detachably connected to the mounting base 1 is provided on the air balancing cover 2, and a plurality of noise-reducing air balancing sheets 21 for reducing wind noise are arranged on the air balancing cover 2.

[0033] In this embodiment, a mounting base 1 and an air distribution cover 2 are provided and grooves are opened inside to clamp and fix the heat dissipation fan 9 to prevent it from shaking. Then, shock-proof corner pads 5 made of rubber material are provided at each corner end of the first mounting groove 3 and the second mounting groove 4 to wrap the corner ends of the heat dissipation fan 9 so that a gap is left between the heat dissipation fan 9 and the outer wall of the fixed structure to prevent the fan from shaking and colliding with the fixed structure to generate noise during operation. The rubber corner pads have good elasticity and softness, can absorb the vibration and impact force generated when the fan is running, prevent it from colliding with the mounting base 1 to generate noise, and provide a more stable and quiet working environment.

[0034] like Figure 2 and Figure 4 As shown, the wind balancing cover 2 of this embodiment is equipped with multiple noise-reducing wind balancing sheets 21 arranged evenly in an array at the fan outlet. The noise-reducing wind balancing sheets 21 are thick in the middle and gradually thin towards both sides, like a wing-shaped fluid. The special shape of the wind balancing sheets can make the airflow smoother when passing through the fan outlet, and reduce turbulence. The gradually thinning wind balancing sheets also help reduce the resistance of the airflow when passing through, further reducing the noise level.

[0035] like Figure 1As shown, in this embodiment, a snap assembly 6 which is easily detachably connected to the mounting base 1 is provided at both sides of the connecting end surface of the bottom of the wind balancing cover 2 and the mounting base 1. The snap assembly 6 extends vertically to both sides of the wind balancing cover 2. The snap assembly 6 includes a snap-on portion 61 and a pressing end 62 which is integrated with the snap-on portion 61 and is used to control the snap-on portion 61 to make elastic pressing displacement. A snap-on hole 7 adapted to the snap-on portion 61 is provided on the mounting base 1, and a fixing piece 611 fixed to the snap-on hole 7 is provided on the snap-on portion 61. The snap-on portion 61 is snapped into the snap-on holes 7 on both sides of the mounting base 1 to form a fixation to prevent the internal fan from shaking and generating noise during operation; when disassembly is required, the pressing end 62 is pressed to make the fixing piece 611 on the snap-on portion 61 make elastic displacement, and the fixation can be cancelled to take out the internal cooling fan 9 for maintenance.

[0036] like Figure 3 As shown, a hole is opened at the bottom of the first mounting slot 3 in the mounting base 1 for ventilation between the cooling fan 9 and the outside, and a dust screen 10 is provided at the hole to prevent dust from entering. The dust and impurities in the air can be filtered effectively to reduce the dust from entering the fan and the inside of the chassis, and the failure rate can be reduced. The dust screen 10 will not block the air flow and thus hinder the operation of the cooling fan 9.

[0037] like Figure 5 As shown, a mounting portion 8 is extended from the mounting base 1 to the periphery of the first mounting groove 3, and the corner ends of the mounting portion 8 are provided with fixing countersunk holes 81 for fixing to the chassis back plate. The mounting base 1 is fixed to the chassis by installing bolts in the fixing countersunk holes 81, so that the fan can be installed and fixed by placing it in the base without the need to install the fan with bolts.

[0038] The working principle of this embodiment is as follows: This embodiment clamps the fan by setting an air balancing cover 2 and a mounting base 1 to fix it, and then a rubber anti-vibration corner pad 5 is provided at the corner end to prevent the fan from shaking during operation and colliding with the fixed structure to generate noise. By installing a noise-reducing air balancing sheet 21 that is gradually thinned from the middle to both sides at the fan outlet, the airflow can be smoothed to reduce the turbulence and noise generated by the fan. The mounting base 1 is then fixed to the chassis by bolts, and a buckle assembly 6 is provided on the air balancing cover 2 to facilitate the removal of the cooling fan 9 for maintenance.

[0039] The embodiments described above are only preferred implementation modes of the present utility model and cannot be used to limit the protection scope of the present utility model. Any non-substantial changes and modifications made by technicians in this field on the basis of the utility model shall fall within the protection scope of the present utility model.
