The icing events for the wind turbine blade is the key problem in the low temperature conditions. Heating is considered to be the most efficient approach to prevent from the ice formation on the turbine blade surface. However, this kind of method consumes a certain amount of energy. In this present study, an anti-icing method, using the heat pipe technology, is proposed to prevent from icing on the blade surface, and the anti-icing energy is from the waste heat generated during the operation of a wind turbine, which can reduce the assumption of the energy. The researches on the anti-icing temperature characteristics of the test model, based on the heat pipe anti-icing method, are carried out in an icing wind tunnel combining with the low natural temperature. The effects of the wind speed and heat source temperature on the heat transfer of heat pipes are investigated. The icing distribution and the temperature change of the anti-icing process of an airfoil with NACA0018 are explored, and the variation of the icing thickness of the airfoil with icing time, under the different heat source temperature conditions, is analyzed. The results indicate that the blade surface temperature, which is lower than 0°C, is more beneficial to the heat transfer of the heat pipe, and the ice prevention, based on the heat transfer of the heat pipe, can achieve a better anti-icing effect.
