AI Technical Summary

Technical Problem

Existing frequency converters have low heat dissipation efficiency and insufficient protection level in harsh environments, resulting in unstable equipment operation.

Method used

A heat dissipation solution combining an internal airflow circulation component and a liquid cooling heat exchange component is adopted. The internal cavity is divided by a partition plate to form multiple circulation air ducts. The airflow is circulated by a circulation fan. Liquid cooling heat exchange elements and coolant cooling units are installed in the air ducts. Combined with air cooling, the temperature consistency of the electrical control cabinet is improved.

Benefits of technology

It improves the heat dissipation efficiency and protection of the frequency converter, extends the service life of components in the electrical control cabinet, and enhances the stability and safety of the equipment.
