Research on Deicing of Optical Widow Heating Based on Transparent Conductive Film
In order to improve the deicing efficiency for transparent conductive film on the surface of circular optical window during heating,through theoretical analysis of the Ohm's law and heat conductive effect,a theoretical model of heating efficiency of transparent conductive film on the surface of circular optical window was established.Based on the numerical simulation of the theoretical model,the deicing efficiency of the circular optical window with a diameter of 100 mm for 10 mm thick ice sheet at-55 ℃ was calculated.The experimental verification was carried out by heating with a 24 V DC power supply.The results show that there is a deviation between the deicing time of the experimental results and the theoretical calculation.The main reason is that in the process of deicing,in addition to most of the heat generated by the optical window surface,a small part of the heat is consumed by heat conduction and heat dissipation,and in the actual process of heating and deicing,part of the water on the window surface is heated and absorbs heat,resulting in increased energy consumption.Based on the experimental results and theoretical analysis,further measures to improve the efficiency of heating deicing are proposed.
