[0031] Please refer to Figures 1 to 4 , the present utility model discloses an intelligent variable frequency control device for an air conditioner unit.

The heat dissipation structure is disposed on the side wall of the box body 100, and the heat dissipation structure is connected to the plurality of heat conducting plates 120. Specifically, the variable frequency module 200 and the control module 300 are respectively mounted on the plurality of mounting plates 110. During actual operation, the heat generated by the variable frequency module 200 and the control module 300 can be absorbed by the heat conducting plates 120 between the mounting plates 110 and transferred to the heat dissipation structure on the inner wall of the box body 100 for heat dissipation, thereby greatly improving the heat dissipation function of the variable frequency control device, and further ensuring that the intelligent variable frequency control device of the air conditioner unit of the present utility model can be applicable to a variety of temperature environments, and avoiding the occurrence of situations such as a decrease in operating efficiency, a decrease in operating stability or even damage to the variable frequency control device caused by high temperature.
