AI Technical Summary

Technical Problem

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.

Method used

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.

Benefits of technology

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.

Abstract

本申请公开了一种发电机散热装置、风力发电机及发电机,其中,发电机散热装置包括壳体、主轴和散热机构,壳体内设有容置空腔,容置空腔用于容纳发电机的转子和定子,且壳体的侧壁上开设有至少一个进风口,进风口与容置空腔连通;主轴至少部分穿设壳体内部;至少两个散热机构沿主轴的轴向间隔设于壳体的相对两侧,且位于主轴的上方;每个散热机构均与容置空腔连通,并在散热机构处形成出风口,散热机构用于抽出容置空腔内的热空气。本申请提供的技术方案,可以减少散热装置对机舱空间的占用,同时散热机构沿主轴轴向间隔设于壳体相对两侧,且设置在主轴上方,避免了散热机构与机舱内壁的直接接触,适配现代风电机舱紧凑化、轻量化的设计要求。
