Description

Technical Field

[0001] This utility model relates to the field of server cooling fan technology, specifically a high-efficiency server cooling fan. Background Technology

[0002] A server cooling fan is a device used for heat dissipation. Its main function is to expel heat from inside the server, ensuring its normal operation and stability. It is typically driven by an electric motor, which generates airflow through rotating blades to expel hot air and maintain the server's temperature within a suitable range.

[0003] Server cooling fans are widely used in data centers and high-performance computing environments to ensure stable server operation and extend their service life. However, traditional server cooling fans have low heat conduction and heat dissipation efficiency. After long-term, high-power use, they are prone to overheating and short circuits, affecting the lifespan of the motor. In addition, traditional fan housings are inconvenient to disassemble, resulting in low disassembly and assembly efficiency and making it difficult to quickly clean and maintain the inside of the fan blades. Therefore, this utility model proposes a server cooling fan with high-efficiency heat conduction and easy disassembly. Utility Model Content

[0010] Preferably, a plurality of evenly distributed sound-insulating rings are fixedly installed on the inner wall of the fan housing.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] Because the fan housing of this invention is made of a high thermal conductivity metal material, the internal heat can be conducted outward through the fan housing. By fixing several heat dissipation fins on the outer surface of the fan housing, the heat dissipation fins can exchange heat with the air outside the fan, thereby effectively improving the heat dissipation efficiency of the fan during operation. It has the practical effect of efficient heat conduction of the housing and efficient heat exchange of the heat dissipation fins, which can effectively prevent the fan from overheating and damage, improve the overall service life of the fan, and has the practical effect of efficient heat dissipation of the fan itself, thus improving the performance.

[0013] Meanwhile, the front panel of the fan is detachably connected to the fan housing, which makes it extremely convenient to quickly disassemble and assemble the front panel. In actual use, the inside of the fan housing can be easily opened, which makes it easy to clean and maintain the internal fan structure regularly, avoid excessive dust accumulation, improve the working quality of the fan, and avoid a lot of noise caused by dust accumulation during the operation of the fan. It has a certain dust removal and noise reduction effect, and the disassembly and assembly efficiency is high, making the structure more convenient to use.

[0014] Furthermore, the fan blade bushing of this utility model is fixedly sleeved on the rotating shaft of the motor, so that the bushing can be easily pulled out during use, thereby facilitating the disassembly and cleaning of the internal fan blades, further improving the disassembly and assembly effect of the fan, and having a good disassembly, assembly and dust cleaning effect, making it highly practical.

[0023] With this structural design, when the fan generates a large amount of heat, the heat inside can be conducted outward through the fan housing 2, which is made of a high thermal conductivity metal material. Several heat dissipation fins 6 are fixedly installed on the outer surface of the fan housing 2, allowing heat exchange between the fins and the outside air. This effectively improves the heat dissipation efficiency of the fan during operation, achieving the practical effects of efficient heat conduction from the housing and efficient heat exchange from the fins 6. This effectively prevents overheating damage to the fan, extends its overall lifespan, and enhances its performance.

[0024] Four symmetrically distributed secondary mating holes 5 are provided on the outer wall of the front side of the fan housing 2. A front panel 3 is provided on the front side of the fan housing 2. The rear panel 1, the fan housing 2, and the front panel 3 together constitute the fan housing assembly of this utility model.

[0025] The outer wall of the front panel 3 is provided with several primary disassembly holes 4 that are adapted to the secondary mating holes 5. Both the primary disassembly holes 4 and the secondary mating holes 5 are threaded holes.

[0026] When it is necessary to assemble the front panel 3, the primary mounting holes 4 of the front panel 3 can be aligned with the secondary mating holes 5 of the fan housing 2. Then, screws for assembly can be installed in the holes to achieve the normal assembly effect of the front panel 3 and the fan housing 2.

[0027] When disassembly is required, simply remove the screws and then remove the front panel 3.

[0028] This fan housing design allows for extremely convenient and quick disassembly and assembly of the front panel 3. In actual use, the interior of the fan housing 2 can be easily opened, facilitating regular cleaning and maintenance of the internal fan structure.

[0035] Working principle: When in use, the cooling fan of this utility model can be installed on the fan bracket through the mounting hole 13, thereby ensuring the normal use of this utility model;

[0036] When the fan generates a large amount of heat, the heat inside can be conducted outward through the fan housing 2, which is made of a high thermal conductivity metal material. Several heat dissipation fins 6 are fixedly installed on the outer surface of the fan housing 2, allowing heat exchange between the fins and the outside air. This effectively improves the heat dissipation efficiency of the fan during operation, achieving efficient heat conduction from the housing and efficient heat exchange from the fins 6. This effectively prevents overheating damage, extends the overall lifespan of the fan, and improves its performance.

[0037] Meanwhile, when it is necessary to assemble the front panel 3, several primary disassembly holes 4 of the front panel 3 can be aligned with the secondary mating holes 5 of the fan housing 2. Then, screws for assembly can be installed in several holes to achieve the normal assembly effect of the front panel 3 and the fan housing 2.

[0038] When disassembly is required, simply remove the screws and then remove the front panel 3.
