摘要
针对当今风电叶片面临的电热除冰能耗巨大及疏水涂层除冰效果欠佳的问题,提出了一种结合电热元件除冰与疏水涂层除冰共同优势的复合除冰系统。借助涂层疏水性表征手段和冰层粘结强度测试实验,分析了疏水性对冰层剪切附着力的影响,最后通过特定环境下的除冰模拟实验对复合除冰系统的可行性与可靠性进行了评估。该除冰系统不但满足风电叶片的除冰要求,而且可降低除冰能耗,起到节能作用,可应用于降低冰脊对叶片造成的损害。
In this paper,a new compound de-icing system combining thermoelectric advantage with hydrophobic superiority is presented,aiming at solving the problem in the wind turbine blade that the energy consumption of thermoelectric is too huge and the effect of the hydrophobic coatings is not satisfied. In order to verify the feasibility and reliability of the compound de-icing system,the specific experiments using GFRP plates containing thermoelectric and hydrophobic coatings were carried out. The compound de-icing system not only meets the de-icing requirement of the wind turbine blade,but also reduces the energy consumption. Furthermore,the compound de-icing system is expected to reduce the damage caused by ice ridge.
