“…When the temperature difference between inside and outside the cabin exceeds 5 ℃, the system automatically switches to the pneumatic heat pipe high-efficiency cooling mode. [8] Due to the application of variable frequency, variable capacity, and pressure ratio technology in the compressor configured in the system, as well as the configuration of a dual electronic expansion valve structure that can adjust the flow rate in a wide range, the natural cold source during the transition season can be fully utilized to achieve energy conservation.…”

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.
