[0061] Figure 2A is a schematic diagram of a fan module according to an embodiment of the present invention, and Figure 2B for Figure 2A A fan module in the fan module is separated from the fan bracket. Please also refer to Figure 2A and Figure 2B The fan module 2 includes a fan 21, a fan frame 22, a pair of quick-release frames and a connector assembly. The fan frame 22 has a bottom wall 221 and a plurality of side walls 222 surrounding the bottom wall 221 to form an accommodating space S, wherein the fan 21 is suitable for being placed in the accommodating space S.

[0062] A quick release bracket 23 is respectively assembled on opposite sides of the fan 21. The connector set includes a first connector 24 and a second connector 25, wherein the first connector 24 is fixed to one of the quick release brackets 23, and the second connector 25 is fixed to the fan frame 22, and the setting position of the second connector 25 corresponds to the setting position of the first connector 24. Therefore, when the fan 21 is placed in the accommodating space S, the first connector 24 and the second connector 25 are plugged into each other. In this embodiment, the orthographic projection of the first connector 24 on the bottom wall 221 of the fan frame 22 falls within the orthographic projection range of the quick release bracket 23 on the bottom wall 221 of the fan frame 22.

[0063] Figure 2C for Figure 2B A schematic diagram of a fan and a fan rack from another perspective, Figure 2D is a schematic diagram of the first connector, and Figure 2E is a schematic diagram of the second connector. Please also refer to Figure 2C , Figure 2D and Figure 2E , the structures of the two quick release frames 23 are different. Specifically, the pair of quick release frames 23 includes a first quick release frame 231 and a second quick release frame 232, wherein the first quick release frame 231 has an escape space E, and the first connector 24 is assembled to the first quick release frame 231, and the first connector 24 is located in the escape space E. In addition, the first quick release frame 231 and the second quick release frame 232 respectively include a body portion 23a and a handle portion 23b, wherein the body portion is assembled to the fan 21, and the handle portion 23b is pivotally disposed on one side of the body portion 23a so as to be rotatable relative to the body portion 23a.

[0064] The first connector 24 is a male connector, and the second connector 25 is a female connector.

[0065] The first connector 24 includes a first circuit board 241, a plurality of first cables 242, a plurality of first terminals 243, and a first alignment structure 244. The first cables 242 are fixed to the first circuit board 241. The first terminals 243 are disposed on the first alignment structure 244 and are electrically connected to the first cables 242 through the first circuit board 241. The first alignment structure 244 is a plurality of plugs, and the first terminals 243 are distributed on two opposite surfaces of the plugs. In this embodiment, the first terminals 243 are pads formed on two opposite surfaces of the plug.

[0066] In addition, the first circuit board 241 has a pair of first locking portions 245 . The first locking portions 245 allow the locking members 3 to pass through correspondingly, so as to lock the first circuit board 241 to the first quick-release bracket 231 .

[0067] The second connector 25 includes a second circuit board 251, a plurality of second cables 252, a plurality of second terminals 253, and a second alignment structure 254, wherein the second cables 252 are fixed to the second circuit board 251, and the second terminals 253 are disposed on the second alignment structure 254 and electrically connected to the second cables 252 through the second circuit board 251. The second alignment structure 254 is a plurality of sockets, and the second terminals 253 protrude from the surface of the sockets facing the plug to be suitable for contacting the first terminals 243.

[0068] In addition, the second circuit board 251 has a pair of second locking portions 255 for the locking member 3 to pass through, and the fan bracket 22 further includes a plurality of studs 223 (shown in FIG. Figure 2B ), disposed on the bottom wall 221 and close to one of the side walls 222, and the locking member 3 passes through the second locking portion 255 and is locked into the stud 223 (shown in FIG. Figure 2B ) to fix the second circuit board 251 to the fan frame 22.

[0069] Please refer to Figure 2C , the user can first assemble the first connector 24 to the first quick-release bracket 231, and fix the second connector 25 to the fan bracket 22. In addition, the first quick-release bracket 231 and the second quick-release bracket 232 are respectively assembled to the two sides of the fan 21.

[0070] When the fan 21 assembled with the quick release bracket 23 is to be assembled to the fan bracket 22, the handle 23b of the quick release bracket 23 can be rotated relative to the main body 23a, so that the handle 23b changes from being against the fan 21 to being upright on the main body 23a. In this way, the user can pass his fingers through the handle 23b to conveniently extract the fan 21.

[0071] Then as Figure 2B As shown, the fan 21 is placed in the accommodating space S of the fan frame 22 .

[0072] Figure 3 This is a schematic diagram of the corresponding plug-in of the first connector and the second connector. Please also refer to Figure 2B and Figure 3 As the fan 21 goes deeper into the accommodation space S, the first connector 24 contacts the second connector 25 and is plugged with the second connector 25. Specifically, the first alignment structure (plug) 244 of the first connector 24 is correspondingly inserted into the second alignment structure (socket) 254 of the second connector 25. When the first alignment structure 244 of the plug and the second alignment structure 254 of the socket are correspondingly plugged with each other, the first terminals 243 provided on the two opposite surfaces of the plug contact the second terminals 253 protruding from the surface of the socket facing the plug, and the first connector 24 and the second connector 25 can achieve electrical conduction.

[0073] So, like Figure 2A As shown, the fan 21 is well assembled in the fan frame 22 .

[0074] After the fan 21 is assembled in the fan frame 22, the handle portion 23b that can pivot relative to the body portion 23a is rotated from the upright state to a state that abuts against the fan 21. In this way, the overall volume of the fan module 2 can be reduced.

[0075] from Figure 2A It can be seen from the fan module 2 that compared with Figure 1In the fan module 1 of the present embodiment, the structures of the first connector 24 and the second connector 25 are changed, and the setting position of the first connector 24 is changed, so that the orthographic projection of the first connector 24 on the bottom wall 221 of the fan frame 22 falls within the orthographic projection range of the quick-release frame 23 on the bottom wall 221 of the fan frame 22. Compared with the known fan module 1, the two fans 21 in the fan module 2 of the present embodiment are set closer, that is, the distance between the two fans 21 is shortened, so that the generation of voids can be avoided, thereby forming an effective wind flow field shape, and improving the overall heat dissipation effect of the fan module 2.

[0076] In addition, since the structure of the first connector 24 and the second connector 25 in this embodiment is different from the structure of the connector in the known fan module 2, and the arrangement of the first connector 24 and the second connector 25 is also different from the arrangement of the connector in the known fan module 1, the space limitation of the known connector structure on the cable is overcome and a high-voltage resistant cable can be selected, thereby improving the current resistance of the fan module 2.

[0077] In summary, in the fan module of the present invention, by making the orthographic projection of the first connector fixed on the quick-release bracket on the bottom wall of the fan bracket fall within the orthographic projection range of the quick-release bracket on the bottom wall of the fan bracket, the distance between fans in the fan module can be effectively reduced, the invalid voids can be reduced, a more effective wind flow pattern can be formed, and the overall heat dissipation effect of the fan module can be improved.

[0078] In addition, the arrangement of the first connector and the second connector in the fan module of the present invention is different from the arrangement of the connector in the known fan module, and the structure of the first connector and the second connector is further different from the structure of the connector in the known fan module. Therefore, the space limitation of the arrangement of the connector in the known fan module for the cable is overcome and a high-voltage resistant cable can be selected according to the needs, thereby improving the current resistance capacity of the fan module.
