[0023] See also Figure 1-Figure 5 A tool-free assembly fan module for a server includes a fan body 3, which is an axial flow fan. The fan body 3 is arranged in a lower shell 1 and an upper shell 2. The ends of the lower shell 1 and the upper shell 2 are both provided with ventilation holes 5. The upper shell 2 is connected to the lower shell 1 in a snap-fit manner. A snap-fit assembly is provided on the mating surface of the lower shell 1 and the upper shell 2, wherein the snap-fit assembly includes a snap groove 11 and a snap 21. The snap 21 is arranged on the circumference of the mating surface of the upper shell 2, and the convex portion of the snap 21 faces upward. On the inner side of the shell 2, a buckle groove 11 is arranged on the circumference of the docking surface of the lower shell 1, and the docking surfaces of the lower shell 1 and the upper shell 2 are also respectively provided with an adaptive limit groove 12 and a limit block 24. When the lower shell 1 and the upper shell 2 are docked, the limit groove 12 and the limit block 24 are docked with each other, which can improve the stability of the docking between the lower shell 1 and the upper shell 2. After the limit groove 12 and the limit block 24 are docked with each other, the bulge of the buckle 21 will be stuck in the buckle groove 11, thereby realizing rapid assembly of the lower shell 1 and the upper shell 2.
[0024] In order to fix the fan body 3 inside the lower shell 1 and the upper shell 2, outwardly protruding fasteners 23 are provided around the interior of the upper shell 2. The buckle protrusion at the end of the fastener 23 is set toward the side of the interior of the upper shell 2. The air outlet end of the fan body 3 is snap-fastened to the fastener 23. A limiting column 15 is provided at the bottom end of the interior of the lower shell 1 corresponding to the mounting hole position of the fan body 3. During installation, the air outlet end of the fan body 3 is first snapped onto the fastener 23 to temporarily fix the fan body 3, and then the lower shell 1 and the upper shell 2 are docked. After the lower shell 1 and the upper shell 2 are docked, the limiting column 15 is inserted into the mounting hole of the fan body 3 to limit and fix the fan body 3 again. In this way, the fan body 3 can be stably fixed in the lower shell 1 and the upper shell 2. A power connector 31 is connected to the fan body 3. A slot 25 for fixing the power connector 31 is provided on one side of the upper shell 2. The power connector 31 is inserted and fixed from the side of the opening on one side of the slot 25.
[0025] There are multiple open-structured shaft grooves 22 on the shell walls on both sides of the upper shell 2, and multiple backflow prevention plates 4 are arranged side by side inside the upper shell 2. The two ends of the backflow prevention plates 4 are rotatably connected to the corresponding shaft grooves 22. The backflow prevention plates 4 are metal plates, which makes the backflow prevention plates 4 more durable and will not age and deform. One side of the backflow prevention plate 4 is formed into a reel 41 by bending the sheet metal, and shaft pins 42 are inserted at both ends of the reel 41. The end of the shaft pin 42 is provided with a rotating shaft 43 that is adapted to the inner diameter of the shaft groove 22. The rotating shaft 43 is inserted into the shaft groove 22. The design structure of the shaft pin 42 and the open shaft groove 22 facilitates the assembly and assembly of the backflow prevention plate 4, reduces the difficulty of installing the backflow prevention plate 4, and improves the production efficiency of assembly.
[0026] A plurality of spring clips 13 are provided on each surface of the lower shell 1, one end of the spring clip 13 is fixedly connected to the lower shell 1, and the other end is a free end. A ball protrusion 14 protruding outward is provided on the free end of the spring clip 13. When the server installs the fan module, a groove that is adapted to the ball protrusion 14 is provided on the fan module installation position of the server. The fan module can be fixed on the fan module installation position of the server without the need for bolts.
[0027] The server fan module of the utility model is assembled without tools. The fan module is assembled by a snap-on method as a whole. It can be installed without tools during disassembly and has an anti-backflow function, making the assembly of the server fan module more convenient and quick. In addition, the anti-backflow plate design with a metal plate structure has high strength and is not easy to age and deform. The axial pin structure is adopted on both sides of the anti-backflow plate, making the assembly structure simple and easy.
[0028] Specifically, when in use, first assemble the anti-backflow plate 4 into the upper shell 2, and then snap-fix the fan body 3 on the upper shell 2, so that the end face of the fan body 3 blocks the shaft groove 22, so that the fan body 3, the anti-backflow plate 4 and the upper shell 2 form an integrated structure, and finally connect the lower shell 1 and the upper shell 2 to realize tool-free installation of the server fan module.
[0029] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
