Technical Field

[0002] With the transformation of the global energy structure and the rapid growth of clean energy demand, wind power generation, as an important part of renewable energy, has continuously improved its installed capacity and technical level. As the core equipment of wind power generation, the operating stability and reliability of wind turbines are directly related to power generation efficiency and economic benefits. As the power of wind turbines has jumped from megawatts to more than 10MW, the power density of core components such as gearboxes, generators, and converters in the cabin has increased significantly, resulting in a sharp increase in heat load per unit volume. For example, the heat dissipation power of a 10MW unit gearbox may exceed 200kW, and traditional heat dissipation methods are difficult to meet the demand. The heat dissipation of traditional wind turbine cabins mainly relies on natural ventilation or a single air cooling system, which has the following problems: Poor environmental adaptability: In high temperature, high humidity or dusty environment, the heat dissipation efficiency drops sharply; Insufficient synergy: Liquid cooling and air cooling systems operate independently and cannot be dynamically adjusted according to real-time working conditions; High energy consumption: Over-reliance on high-power fans or water pumps increases operating costs. Therefore, how to combine the advantages of air cooling and liquid cooling and achieve synergistic heat dissipation through dynamic multi-parameter control has become an important issue that needs to be solved in the current field of wind power generation technology.
