Abstract Offshore wind power is regarded as an important part of the future large-scale renewable power generation portfolio, and offshore wind power is the main development direction of the future wind power industry. The high power generator has a high requirement on the unit heat dissipation, so the temperature field analysis of the generator can be a good guide for the design of the generator cooling system. Compared with the natural air-cooled generator, the forced water-cooled generator has the advantages of better heat dissipation, less noise and longer service life. In this paper, an external rotor permanent magnet direct drive wind generator is taken as the research object. Based on the analysis method of fluid-solid coupling and conjugate heat transfer, the temperature field of thegenerator under normal operation is analyzed by using ANSYS software, so as to obtain the temperature distribution of the main components in the generator. Finally, through the fluid structure coupling analysis of a 10MW external rotor generator, the temperature rise distribution of generator under different cooling water flow rates is compared and calculated, and the relationship curve between cooling fluid flow rate and generator temperature rise is obtained, which provides reference for generator cooling design.
