AI Technical Summary

⚠Technical Problem

Existing direct-drive fan frequency converters are large in size and occupy a large area, and need further improvement to reduce their size and improve space utilization efficiency.

⚗Method used

Adopting a modular design, the inverter body is arranged in layers, consisting of a mounting base plate, a drive board, and a control main board, and is connected by detachable support columns and conductive copper columns. Taking advantage of the good thermal conductivity of copper or aluminum materials, heat is dissipated by the airflow carried away by the fan during operation.

🎯Benefits of technology

This results in a more compact inverter structure, saving space and reducing the overall volume. It also reduces heat through thermally conductive materials and fan cooling, eliminating the need for additional heat dissipation mechanisms and improving maintenance convenience and stability.
