Converter Liquid Cooling Plate Application Cases

Why Wind Turbine Converters Need Advanced Cooling Solutions

Wind turbine converters play a critical role in regulating power flow, ensuring grid stability, and maintaining optimal turbine performance. However, prolonged operation generates excessive heat, pushing core temperatures beyond 150°C—leading to component burnout, system failures, and even explosions.

Traditional air-cooling systems struggle to maintain efficiency, while heat pipe cooling offers limited improvements. In contrast, liquid cooling plates deliver unmatched thermal performance, ensuring stable operation, extended lifespan, and enhanced safety for wind energy systems.
