Description

Technical Field

[0001] The utility model belongs to the technical field of rectifiers, in particular to a rectifier for a cooling fan of a server. Background Art

[0002] A server is a type of computer that runs faster, has a higher load, and is more expensive than an ordinary computer. A server provides computing or application services to other clients (such as PCs, smartphones, ATMs, and even large devices such as train systems) in the network. The server has high-speed CPU computing power, long-term reliable operation, strong I / O external data throughput, and better scalability. When the server is in use, it will generate high temperature, and a cooling fan is usually used to dissipate the heat. Since the cooling fan rotates when working, it causes high-frequency vibration inside the device. In order to suppress the vibration, a rectifier is usually used.

[0003] For example, announcement number CN209557342U discloses a cooling fan rectifier for a server. The rectifier rectifies the gas by setting a rectifier net. However, since the rectifier net is relatively thin, its rectifier effect gradually decreases as the gas flow rate increases. In order to solve the above problem, a cooling fan rectifier for a server is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a heat dissipation fan rectifier device for a server in order to solve the above problem.

[0005] The technical solution adopted by the utility model is as follows: A heat dissipation fan rectifier device for a server, comprising:

[0006] A fixing mechanism, which is fixedly mounted on the outer wall of the heat dissipation fan housing, the fixing mechanism also includes a mounting plate, a wind shield is integrally provided on the rear side of the mounting plate, and a plurality of mounting holes are opened on the front side of the mounting plate;

[0007] The rectifying mechanism is fixedly installed inside the mounting hole. The rectifying mechanism also includes a rectifying cylinder. A plurality of air flow holes are arranged through the rectifying cylinder.

[0008] Through the above technical scheme, when using the rectifier, the rectifier cylinder is first fixedly installed inside the mounting hole, and then the mounting plate is fixedly installed on the outer wall of the cooling fan. During the operation of the cooling fan, the wind force generated by the cooling fan enters the wind cover, and then enters the corresponding rectifier cylinder through the wind cover. Since a plurality of air flow holes are arranged inside the rectifier cylinder, the high-speed air flow is dispersed by the air flow holes, and the air flow holes are relatively slender, thereby converting the irregular air flow into a straight-line air flow and discharging it.

[0009] In a preferred embodiment, a filter screen is fixedly installed on the outermost side of the air flow hole.

[0010] The above technical solution can effectively prevent dust and other impurities in the air flow from blowing toward the server.

[0011] In a preferred embodiment, the radius of the air flow hole gradually decreases from both ends to the center.

[0012] Through the above technical solution, when the gas flows in the air flow hole and reaches the narrowest point in the center of the pipe, the dynamic pressure reaches the maximum value and the static pressure reaches the minimum value. The gas velocity increases due to the reduction in the cross-sectional area of ​​the flow, thereby pressurizing the gas and improving the heat dissipation effect.

[0013] In a preferred embodiment, connecting pieces are integrally provided on both the left and right sides of the wind shield, and a clamping block is provided on the inner wall of the connecting piece.

[0014] Through the above technical solution, the air cover is connected to the cooling fan through the connecting piece and the clamping block, which is convenient for installation and disassembly.

[0015] In a preferred embodiment, the number of the rectifying mechanisms, the mounting holes and the heat-dissipating fans is the same.

[0016] In a preferred embodiment, the rectifying mechanism and the mounting hole are fixed by threaded fitting.

[0017] The above technical solution makes it easy to remove the rectifying mechanism from the mounting hole for cleaning.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are as follows: the utility model provides a heat dissipation fan rectifier device for a server.

[0019] 1. When using the rectifier, first fix the rectifier tube inside the mounting hole, and then fix the mounting plate on the outer wall of the cooling fan. When the cooling fan is working, the wind generated by the cooling fan enters the wind cover, and then enters the corresponding rectifier tube through the wind cover. Since there are multiple airflow holes inside the rectifier tube, the high-speed airflow is dispersed by the airflow holes, and the airflow holes are relatively slender, so that the irregular airflow becomes a straight-line airflow and is discharged.

[0020] 2. When the gas flows through the air flow hole and reaches the narrowest point in the center of the pipe, the dynamic pressure reaches the maximum value and the static pressure reaches the minimum value. The gas velocity increases due to the decrease in the cross-sectional area of ​​the flow, thereby pressurizing the gas and improving the heat dissipation effect. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example:

[0029] A heat dissipation fan rectifying device for a server, comprising:

[0030] The fixing mechanism 1 is fixedly mounted on the outer wall of the heat dissipation fan housing. The fixing mechanism 1 also includes a mounting plate 11. A wind shield 12 is integrally arranged on the rear side of the mounting plate 11. Connecting pieces 14 are integrally arranged on the left and right sides of the wind shield 12. A clamping block 15 is arranged on the inner wall of the connecting piece 14. The wind shield 12 is clamped with the heat dissipation fan through the connecting piece 14 and the clamping block 15, so that it is easy to install and disassemble. A plurality of mounting holes 13 are opened on the front side of the mounting plate 11.

[0031] The rectifying mechanism 2 is fixedly installed inside the mounting hole 13. The number of the rectifying mechanism 2, the mounting hole 13 and the heat dissipating fan is the same. The rectifying mechanism 2 and the mounting hole 13 are fixed by threaded cooperation, so that the rectifying mechanism 2 can be removed from the mounting hole 13 for cleaning. The rectifying mechanism 2 also includes a rectifying cylinder 21. A plurality of airflow holes 22 are provided inside the rectifying cylinder 21. When the rectifying device is used, the rectifying cylinder 21 is first fixedly installed inside the mounting hole 13, and then the mounting plate 11 is fixedly installed on the outer wall of the heat dissipating fan. During the operation of the heat dissipating fan, the wind force generated by the heat dissipating fan enters the wind cover 12, and then enters the corresponding rectifying cylinder 21 through the wind cover 12. Since a plurality of airflow holes 22 are provided inside the rectifying cylinder 21, the high-speed airflow is dispersed by the airflow holes 22, and the airflow holes 22 are relatively slender, so that the irregular airflow is converted into a straight-flowing airflow and discharged.

[0032] A filter 23 is fixedly installed on the outermost side of the air flow hole 22, which can effectively prevent dust and other impurities in the air flow from blowing toward the server. The radius of the air flow hole 22 gradually decreases from both ends to the center. When the gas flows in the air flow hole 22 and reaches the narrowest point in the center of the pipeline, the dynamic pressure reaches the maximum value and the static pressure reaches the minimum value. The speed of the gas increases due to the reduction in the cross-sectional area of ​​the flow, thereby pressurizing the gas and improving the heat dissipation effect.

[0033] Working principle:

[0034] When using the rectifier, first fix the rectifier tube 21 inside the mounting hole 13, and then fix the mounting plate 11 on the outer wall of the cooling fan. When the cooling fan is working, the wind generated by the cooling fan enters the wind cover 12, and then enters the corresponding rectifier tube 21 through the wind cover 12. Since a plurality of airflow holes 22 are arranged inside the rectifier tube 21, the high-speed airflow is dispersed by the airflow holes 22, and the airflow holes 22 are relatively slender, thereby converting the irregular airflow into a straight-line airflow and discharging it.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
