Description

Technical Field

[0001] The utility model belongs to the technical field of server fans, in particular to a server fan test module. Background Art

[0002] The server has high-speed CPU computing power, long-term reliable operation, strong I / O external data throughput capacity and better scalability. According to the services provided by the server, generally speaking, the server has the ability to respond to service requests, provide services, and guarantee services. The server is an important data processing hardware product, which has important application support in the fields of AI intelligence, big data processing, edge computing, etc. Its manufacturing process is complex and the quality control is strict.

[0003] The server fan module is installed in the server and dissipates heat from the internal components of the server through the rotation of the fan. A protective net is usually installed at the rear of the server fan module to prevent operators from contacting the internal fan blades and wires, and to avoid electrical and mechanical injuries.

[0004] The mesh size of the server fan module protection net is related to the distance between the net and the internal components (fan blades, wires, etc.). When designing the server fan module protection net, a test finger of a certain size needs to be used for safety testing, that is, the test finger is inserted into the mesh of the protection net to test whether the end of the test finger will contact the internal components. The safety standard needs to meet the test finger when inserted, and it will not contact the internal components. The mesh size of the protection net directly affects the heat dissipation effect of the server fan module.

[0005] When designing a server fan module, the current design challenge is how to simultaneously meet safety test standards and the optimal heat dissipation effect of the server fan module when the internal space of the server is compact. Utility Model Content

[0006] In order to solve the problem that the current design of a server fan test module cannot meet the safety test standards and the optimal heat dissipation effect of the server fan module when the internal space of the server is compact, the utility model provides a server fan test module.

[0007] The utility model is realized by the following technical solutions:

[0008] A server fan test module comprises a protective net and a mainboard connection module, a fan body and a protective net installation module which are connected and installed in sequence. The protective net is provided with a plurality of mesh holes. The edge of the protective net is folded with a folded edge which can be fitted with the protective net installation module. The folded edge is provided with a long strip installation hole. The installation hole is penetrated with a screw which can be screwed and installed with the protective net installation module.

[0009] A further improvement of the utility model is that a guide bar is provided on the inner side of the folded edge, and a guide groove which cooperates with the guide bar for sliding guidance is opened on the protective net installation module.

[0010] A further improvement of the utility model is that the edge of the mounting hole is provided with a scale mark capable of indicating the position of the screw.

[0011] A further improvement of the utility model is that the mounting hole is a stepped hole structure.

[0012] A further improvement of the utility model is that the protective net is rectangular, and the mounting holes are opened at the upper and lower edges of the folded edges on the left and right sides.

[0013] A further improvement of the utility model is that the guide strip is arranged at the middle of the folded edges on the upper and lower sides.

[0014] A further improvement of the utility model is that a handle is connected and installed on a side of the protective net away from the fan body.

[0015] A further improvement of the present invention is that an unlocking handle is installed on the inner side of the handle through a rotating shaft, and a locking protrusion is provided at one end of the unlocking handle; a through hole is provided on the folded edge on one side for the locking protrusion to extend out; a spring is installed between the handle and the unlocking handle, and the spring can exert elastic force on the locking protrusion to extend in the direction of the through hole.

[0016] A further improvement of the utility model is that a plurality of slots are provided on the folded edge, and elastic gaskets are mounted on the slots.

[0017] A further improvement of the utility model is that the mainboard connection module, the fan body and the protection net installation module are connected and installed through four connecting rods.

[0019] By loosening the screws, the distance between the protective net and the internal fan blades can be flexibly adjusted, so that the safety standard test can be achieved through the test finger to ensure the safety standard, and the specific heat dissipation effect of the fan module can be judged through actual operation. Under the condition of a certain installation space for the service fan module, the mesh size (related to the heat dissipation effect, the larger the mesh, the better the heat dissipation effect) and the distance between the protective net and the fan blade (or conductive component) (the larger the distance, the smaller the mesh, the more in line with the safety standard) can be better adjusted, so that the optimal heat dissipation effect can be achieved while meeting the safety test standards, providing a flexible and convenient test module for the design of the server fan module. The overall structure is simple, easy to use, and practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] This server fan test module can be used as a test module for server fans and can be normally installed in the server; by loosening the screws, the distance between the protective net 4 and the internal fan blades (or conductive components) can be flexibly adjusted, so that the safety standard test can be achieved through the test finger to ensure the safety standard, and the specific heat dissipation effect of the fan module can be judged through actual operation. Under the condition that the installation space of the service fan module is certain, the size of the mesh 46 (related to the heat dissipation effect, the larger the mesh 46, the better the heat dissipation effect) and the distance between the protective net 4 and the fan blades (or conductive components) (the larger the distance, the smaller the mesh 46, and the more in line with the safety standard) can be better adjusted, so that the optimal heat dissipation effect can be achieved under the condition of meeting the safety test standard, providing a flexible and convenient test module for the design of the server fan module. The overall structure is simple, easy to use, and practical.

[0030] like Figure 2 , 4 As shown, the inner side of the fold is provided with a guide bar 45 in the front-to-back direction, and the protection net installation module 3 is provided with a guide groove 32 that cooperates with the guide bar 45 for front-to-back sliding guidance. Through the front-to-back sliding cooperation between the guide bar 45 and the guide groove 32, the protection net 4 can be flexibly and stably adjusted forward and backward to ensure the accuracy of the test.

[0031] In order to make the adjustment position intuitive and digital, the edge of the mounting hole 43 is provided with a scale mark that can indicate the position of the screw.

[0032] In order to ensure that the screw installation does not protrude from the folded edge surface, the installation hole 43 is a stepped hole structure to ensure the reliability of the overall installation of the fan module.
