Super-hydrophobic material and vibrating deicing coupled active and passive anti-icing device and method

Abstract

The invention discloses a super-hydrophobic material and vibration deicing coupled active and passive anti-icing device and method. The device and method aim to solve the problems that the icing phenomenon of the surface of an aircraft part cannot be completely eradicated only by means of a super-hydrophobic surface, and deicing is not thorough through a traditional mechanical deicing method. The device comprises a hydrophobic material thin film, a flexible piezoelectric fiber thin film, an acceleration sensor, a dynamic analysis module, a function generator, a power amplifier and a power source, wherein the acceleration sensor is used for measuring the vibration of the flexible piezoelectric fiber thin film. According to experiment simulation environments and icing meteorological conditions under a real atmospheric environment, the hydrophobic material thin film and the flexible piezoelectric fiber thin film are used and matched with each other, and by means of vibration control over on the flexible piezoelectric fiber thin film, the purpose of low-energy-consumption deicing is achieved. The device can be used for surface deicing treatment of various airplanes, wind turbines, high-speed trains, electric transmission lines and other easily-frozen parts, and is wide in application range, high in value, good in prospect and worthy of large-scale popularization and application.
