Wind turbine nacelle cooling systems: A review

摘要

The thermal load in the wind turbine nacelle is increasing due to the higherdissipation of heat from the various components in the high unit capacity windmill. With the motive to develop a sustainable and efficient windmill, researchon low cost highly efficient wind turbine nacelle cooling systems has becomeparticularly important. In this review, the prominent waste heat producingsources and the extensively used cooling systems are described. A detailedanalysis of the advantages and limitations of each system and the use of variouscooling fluids as cooling medium in wind turbine nacelle cooling systemsis also discussed. Use of nanofluids as cooling medium in liquid cooling systemis also highlighted as it produces a higher thermal performance enhancement.Hence, it is identified as a promising option for a cooling medium and futureresearch.
