When the first fixing plate 140 and the mounting bracket 110 are connected, the installation difficulty can be reduced, and the production efficiency of the assembly process of the air guide assembly 100 can be improved.

[0073] See also Figure 5It can be seen that the first limit block 423 and the second limit block 433 are not solid structures, so the weight of the first limit block 423 and the second limit block 433 can be reduced, and then the weight of the first fixed plate 140 can be reduced, thereby reducing the processing cost and installation difficulty of the first fixed plate 140, and improving the production efficiency of the assembly process of the air guide assembly 100.

[0084] Exemplarily, the axis of the fan 150 overlaps with the axis of the air guide ring 170 .

[0085] See also Fig. 10A and Fig. 10B An air inlet 151 is provided on a side of the fan 150 facing the air guide ring 170 , and an air outlet 171 is provided on a side of the air guide ring 170 facing the fan 150 . The air inlet 151 is communicated with the air outlet 171 .

[0086] See also Fig. 10A and Fig. 10B One end of the air guide ring 170 with an air outlet 171 is partially embedded in one end of the fan 150 with an air inlet 151, thereby realizing that the air inlet 151 of the fan 150 is connected with the air outlet 171 of the air guide ring 170, and because the fan 150 and the air guide ring 170 are embedded in each other, a sealed air inlet channel is formed between the air guide ring 170 and the fan 150, thereby preventing the wind entering from the air guide ring 170 from leaking at the connection between the air guide ring 170 and the fan 150, thereby increasing the air output of the fan 150.

[0087] Exemplarily, the mounting bracket 110 , the first fixing plate 140 , the fan 150 , the second fixing plate 160 , and the air guide ring 170 are all made of metal.

[0088] See also Figure 1 The air guide assembly 100 also includes a motor 180, which is arranged on a side of the first fixed plate 140 away from the fan 150. The output shaft of the motor 180 passes through a through hole on the first fixed plate 140 and is fixedly connected to the fan 150, so that the motor 180 can be used to drive the fan 150 to rotate.

[0089] See also Figure 1 The fan 150 may be a centrifugal fan, and the air outlet 171 of the fan 150 is located on the side of the fan 150, that is, the air is discharged radially along the fan 150. Since the centrifugal fan 150 has the advantages of low noise, high air volume, long air supply distance, and compact structure, it is suitable for precision air conditioning in a computer room.

[0090] See also Figures 6 to 10B The installation process of the air guide assembly 100 provided in the embodiment of the present application may include:

[0091] Step 1: Please refer to Figure 6 , fix the first fixing plate 140 and the fan 150 together, and push the first fixing plate 140 from the outside to the inside along the first crossbeam 120 and the second crossbeam 130;

[0092] Step 2: Please refer to 7A to 10B When the first limit block 423 and the second limit block 433 on the first fixing plate 140 correspond to the first recessed structure 223 on the first beam 120 and the second recessed structure 323 on the second beam 130, respectively, the first limit block 423 and the second limit block 433 enter the first recessed structure 223 and the second recessed structure 323, respectively. At this time, the first fixing plate 140 sinks and cannot be pushed inward any further, thereby completing the positioning of the first fixing plate 140 and the fan 150;

[0093] in, Fig. 7A and Figure 7B The first limit block 423 and the second limit block 433 correspond to the first recessed structure 223 and the second recessed structure 323 respectively but have not yet entered the first recessed structure 223 and the second recessed structure 323. Fig. 8A and Figure 8B As shown, a gap is maintained between the fan 150 and the air guide ring 170, and no interference occurs. This is because the first limit block 423 and the second limit block 433 raise the height of the first fixing plate 140, so that the fan 150 always maintains a higher position during the process of being pushed from the outside to the inside, so as to avoid collision with the air guide ring 170;

[0094] Fig. 9A and Fig. 9B The first limit block 423 and the second limit block 433 respectively enter the first recessed structure 223 and the second recessed structure 323. Fig. 10A and Fig. 10B As shown, the first fixing plate 140 and the fan 150 are positioned, and one end of the air guide ring 170 having the air outlet 171 is partially embedded in one end of the fan 150 having the air inlet 151, thereby achieving a sealed connection between the air inlet 151 of the fan 150 and the air outlet 171 of the air guide ring 170.
