Specifically, as Figure 2 As shown, the special screw 3 and the fan module 2 form a non-detachable structure, so that the special screw 3 is hung on the fan module 2, and the special screw 3 realizes axial movement on the fan module 2 through the cooperation of the slide bar 302 and the screw hole 201, breaking through the screw connection method of the traditional screw, thereby simplifying the installation operation steps of the threaded connection, and further realizing the rapid installation and removal of the rack 1 and the fan module 2. Among them, a plurality of evenly distributed fans are installed on the fan module 2, so that the fans are integrated on the fan module 2.

[0027] As a preferred example, Figure 4 As shown, a countersunk hole 1011 is provided on the threaded sleeve 101, and the diameter of the countersunk hole 1011 is larger than the diameter of the thread tip 303 to guide the thread tip 303. Specifically, the thread tip 303 of the special screw 3 first passes through the countersunk hole 1011 for initial positioning, and then enters the threaded sleeve 101 for precise thread connection. When the fan module 2 is installed with the rack 1, the special screw 3 is axially pushed in, and after being guided by the countersunk hole 1011 on the threaded sleeve 101, the thread tip 303 of the special screw 3 can be smoothly screwed into the thread on the threaded sleeve.

[0028] Preferably, a conical tip 3031 is provided at one end of the thread tip 303 away from the slide rod 302 , and the conical tip 3031 cooperates with the countersunk hole 1011 for guidance, further facilitating precise threaded connection between the special screw 3 and the threaded sleeve 101 .

[0029] As a preferred example, Figure 3 As shown, the screw handle 301 is circular, and a concave-convex structure is provided on the side of the screw handle 301, so as to facilitate the operator to manually turn the special screw 3. At the same time, it can be understood that the shape of the screw handle 301 is not limited to a circle, and can also be an "I" shape, a "X" shape, etc., as long as the operator can manually turn the special screw 3 to achieve the tightening and loosening of the special screw 3.

[0030] Preferably, a guide structure is provided between the rack 1 and the fan module 2, so that the rack 1 and the fan module 2 are aligned through the guide structure. Specifically, the guide structure ensures that the fan module 2 can move smoothly along a predetermined track during the installation process, and finally achieves precise alignment with the rack 1. Optionally, in a specific embodiment, a slide rail is installed on the rack 1, and a slider matching the slide rail is installed on the fan module 2. After the slider is aligned with the slide rail, the fan module 2 is pushed. After the fan module 2 slides along the slide rail to a suitable position, the rack 1 and the fan module 2 are fastened using a special screw 3.

[0031] As a preferred example, Figure 5 As shown, the rack 1 is provided with a guide pin 4, and the fan module 2 is provided with a guide sleeve 5.

It can be understood that the guide pin 4 and the guide sleeve 5 only need to match each other. The guide pin 4 can be installed on the rack 1 or the fan module 2 according to actual conditions, and the guide sleeve 5 can be installed on the fan module 2 or the rack 1 in cooperation with the guide pin 4. Figure 5 As shown, it is a schematic diagram of the guide tip 4 of the present invention being installed on the frame 1, and the guide sleeve 5 being installed on the fan module 2 in cooperation; Figure 6 , which is a schematic diagram of the guide tip 4 of the present invention being installed on the fan module 2 and the guide sleeve 5 being installed on the rack 1 in coordination therewith.

[0032] Preferably, the guide sleeve 5 includes a connected conical concave hole 501 and a positioning through hole 502, and the guide tip 4 is guided by the conical concave hole 501 and then enters the positioning through hole 502 to position the guide tip 4 and the guide sleeve 5. Specifically, the guide tip 4 first passes through the conical concave hole 501 for initial positioning, and then enters the positioning through hole 502 for accurate secondary positioning.

[0033] Preferably, the guide tip 4 includes a positioning tip 401 and a positioning cone 402 connected in sequence, the positioning cone 402 matches the shape of the conical recessed hole 501, and the positioning tip 401 enters the positioning through hole 502 after being guided by the conical recessed hole 501.

The special screw 3 is turned and tightened. The special screw 3 presses the fan module 2, and at the same time, the positioning cone 402 and the conical recessed hole 501 are pressed against each other to complete the installation; during disassembly, the special screw 3 is loosened, and the fan module 2 is pulled downward until the fan module 2 can be lifted up, and the fan module 2 is taken away to complete the disassembly.

[0037] Compared with the traditional way of fixing the fan on the rack 1, the present invention modularizes the multi-fan design to form an integrated fan module 2. The fan module 2 can be quickly disassembled and assembled, and tool-free quick replacement of the fan is achieved. Dust is easily accumulated on the fan module 2, resulting in abnormal operation, which in turn affects the heat dissipation effect. After the fan module 2 is designed as an independent and quickly disassembled structure, daily inspection and cleaning of the fan on the fan module 2 and other maintenance work are greatly facilitated, dust can be removed in time, and the stability of the fan speed is ensured. The fan module 2 is an independent spare part, which avoids the waste of resources fixed to the rack 1, and reduces the "equipment life cycle cost" to a certain extent.
