Two phase flow evaporative cooling technology for wind turbine cabin group

Abstract

The thermal management of wind turbines is an important guarantee for their long-term stable and reliable operation. This article combines a new type of pump driven two-phase flow cooling system with the heat dissipation system of wind turbines, compares wind turbines using two-phase flow cooling systems, studies their system performance during simulated operation in a certain wind turbine cabin, and conducts fitting research and performance analysis on their thermal characteristics. The results indicate that a water cooling system with a flow rate of 3L/min can provide heat dissipation that can be achieved using only a two-phase flow cooling system with a flow rate of 0.05L/min. In transitional seasons and winter conditions, utilizing pneumatic heat pipe technology and fluorine pump technology for refrigeration, fully utilizing natural cooling sources, the annual energy efficiency ratio (AEER) reaches 8-10, and the new heat dissipation technology can ensure the long-term reliable and safe operation of future wind turbines.
