AI Technical Summary

Technical Problem

In existing air-suspended centrifugal blowers, the frequency converter and the blower main unit share the same heat dissipation duct, resulting in low heat dissipation efficiency and serious cross-heating. This is especially prone to causing equipment overheating under high load conditions, affecting system stability and lifespan.

Method used

The enclosure is divided into a main chamber and a secondary chamber by a partition. The inverter has an independent cooling structure, which forms an independent heat dissipation path through the air outlet duct and the inverter cooling fan. Combined with natural convection and forced exhaust, it achieves directional heat dissipation and reduces the impact of heat cross.

Benefits of technology

It improves the heat dissipation efficiency of the frequency converter and the blower main unit, reduces the impact of heat cross-contamination, extends the service life of the equipment, and enhances the stability and performance of the system.
