Offshore wind power is an important field for the development of renewable energy, an important force to promote the advancement of wind power technology and industrial upgrading, and an important measure to promote the adjustment of energy structure. my country is rich in offshore wind energy resources. Accelerating the construction of offshore wind power projects is of great significance to promoting the control of atmospheric haze in coastal areas, adjusting energy structure and transforming the mode of economic development. Wind is a new energy source with great potential. Converting wind kinetic energy into mechanical kinetic energy, and then converting mechanical energy into electrical kinetic energy, this is wind power generation.

However, the power changes of the existing wind power generation system and the excessive heat inside the control box can easily lead to overheating in the box and cause the power generation system to fail. The heat dissipation effect is poor and the practicality is poor. Summary of the invention
