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.
