AI Technical Summary
Existing frequency converters have poor heat dissipation efficiency, which leads to temperature accumulation, affecting component aging and electrical performance. In particular, their insufficient heat dissipation capacity in high-temperature or enclosed environments can easily cause equipment failure.
It adopts a water-cooled heat dissipation structure, forming a closed-loop water-cooling system through the combination of serpentine water-cooled circulation pipes, coolers and cooling fans. Combined with auxiliary air cooling, it enhances heat dissipation efficiency and is designed with modular heat dissipation components for easy maintenance.
It improves the heat dissipation capacity of frequency converter transformers, reduces maintenance costs and operational risks, avoids oil port blockage, achieves efficient temperature management, and extends equipment life.
