AI Technical Summary
The existing high-power wind turbine cooling devices are bulky and heavy, making installation and maintenance difficult, occupying a lot of nacelle space, and easily interfering with the inner wall of the nacelle. They are difficult to adapt to the development trend of modern wind turbine nacelles towards compactness and lightweight design.
Multiple small heat dissipation mechanisms are arranged axially along the main shaft on opposite sides of the housing and above the main shaft to form a multi-channel exhaust structure, avoiding contact with the inner wall of the cabin. The cavity is divided by a baffle plate to form an independent flow guiding cavity, ensuring the directional flow of cooling air and the rapid extraction of hot air.
It reduces the space occupied by the heat dissipation device in the nacelle, improves heat dissipation efficiency and ease of operation and maintenance, adapts to the compact design requirements of modern wind turbine nacelles, avoids uneven cooling and wind path interference, and ensures stable operation of the generator.
