DISPOSITIVO DE ELIMINACION Y PREVENCION DE FORMACION DE HIELO EN SUPERFICIES

Device (1) for eliminating and/or preventing ice formation on surfaces, based on the generation of short-wavelength acoustic waves (OAs), which comprises: - a substrate (2) made of a piezoelectric or ferroelectric material coincident with a surface on which the formation of ice is eliminated and/or prevented, the substrate (2) having one of its faces (A), on which the ice accumulates, exposed to the medium, - one or more electrodes (3), deposited on the substrate (2), and configured to cause mechanical oscillations and local polarization electric fields of an oscillating nature on said substrate; - a vector network analyzer (7), connected to the electrodes (3), and configured to determine the resonance frequency of the substrate (2), and - an excitation module, connected to the electrodes (3) and ground, which It comprises a function generator (6) and a signal amplifier (4), where the function generator (6) is in communication with the vector network analyzer (7), the excitation module being configured to apply to the electrodes (3) an AC electrical signal in the frequency range of MHz, whose frequency coincides with the resonance frequency of the substrate (2) measured with the vector network analyzer (7), - an automatic switching unit (8), connected alternatively between the excitation module and the electrodes (3) or between the vector network analyzer (7) and the electrodes (3).
