Specifically, the air guide ring 11 defines an air flow channel 11a, the motor support 12 is arranged on the guide ring 11 and is located in the air flow channel 11a, the motor support 12 defines a forward-opening placement space 121a, and the motor 13 is mounted on the air flow channel 11a. placed in the space 121a. The fan blade 14 is connected with the motor 13 to be driven to rotate by the motor 13 . The motor cover 15 is located at the front side of the motor 13 , and the motor cover 15 is connected with the motor bracket 12 to fix the motor 13 . It can be seen that the structure of the fan assembly 1 is simple and reliable. When the motor 13 is running, the motor 13 drives the fan blades 14 to rotate, so that the airflow enters the airflow channel 11a from the air inlet end of the fan assembly 1 under the action of negative pressure, and then flows along the airflow channel 11a to the air outlet end. Therefore, the air guide function of the fan assembly 1 can be realized. It should be noted here that “opening forward” means that the opening faces the air outlet end of the fan assembly 1 in the flow direction of the airflow.

It can be seen that, when assembling the motor 13, the motor 13 can be packed into the placement space 121a from the front side of the motor bracket 12, and then the motor cover 15 is sealed with the motor bracket 12 by the front side of the motor bracket 12 and placed in the placement space 121a. Connected, so that the motor 13 can be fixed on the motor bracket 12. At the same time, it can be seen that when the motor 13 needs to be repaired, the motor 13 can be taken out from the placement space 121a only by detaching the motor cover 15 from the motor bracket 12, so that the assembly and maintenance of the fan assembly 1 can be improved to a certain extent. Efficiency, simplify the working procedure of maintenance motor 13. In particular, when the fan assembly 1 is assembled in the refrigeration equipment, it is not necessary to disassemble the guide ring 11 and the motor bracket 12 when maintaining the motor 13, which improves the disassembly and maintenance efficiency of the motor 13 and reduces the operation steps of maintenance personnel.

At the same time, it should be noted that the fan blade 14 may be located at the rear side of the motor bracket 12 or at the front side of the motor cover 15 . It is sufficient to ensure the reliability of the operation of the fan assembly 1 .
