Since power electronic devices require heat dissipation, many fans are present in air-cooled power electronic devices.

[0003] The existing fan fixation methods are mainly as follows:

[0004] 1. The fan is fastened to the fan fixing plate by bolts, and the fan fixing plate is fastened to the cabinet body by bolts. This fixing method requires bolt locking. Generally, the fan is placed on the top of the cabinet body, which is difficult to operate. In addition, it is difficult to operate in some narrow spaces. In addition, the vibration of the fan operation is easily transmitted to the cabinet body, causing noise.

[0005] 2. The fan is fixed by a bracket assembly structure. This structure still requires many bolts to be locked, which makes the assembly complicated and tedious, inconvenient to operate, and has low assembly efficiency. Summary of the Invention
