Description

"INVISIBLE SYSTEM OF ANTIFOGGING AND ANTIFREEZING FOR TRANSPARENT AND NON TRANSPARENT LARGE SURFACES"
The present invention relates to the application of a transparent electro-conductor pattern as electrical resistance as anti-fogging and/or anti-freezing, when powered by an external source of energy, to transparent and non transparent surfaces, such as a motorbike helmet windshield or an aircraft tail; the present invention relates also to the geometry of the electro-conducting pattern, and the suggested method to produce it on a large area at room pressure and temperature.
Depending on the deposition technical parameter the transparent electro-conductor can be a reflector and/or absorber and/or transmitter media at different wave length.
Several transparent conductors (ITO, Anatase, etc) have been developed and there are many methods to produce a deposition film or coating of substrates. These methods to produce electro-conducting film need vacuum, controlled atmosphere. These methods are not working at room temperature and pressure, without controlled atmosphere and mainly are not able to treat large area of substrate. The needs of a large treated surface have been solved with the proposed invention. The present invention is related to the coating of large solid surfaces with a transparent electro-conductor in order to change the optical properties of the treated surfaces.
When on a surface ice or water are present, the optical properties of surface changes. With the deposition of the electro-conductor, depending on the deposition parameter as temperature, deposition rate, atmosphere, thickness, the optical properties of surfaces as reflectance, absorbance and transmittance are changed by the use of the electro-conductor as heater and defogging and/or anti-freezing effect is obtained.
To solve defogging and anti-freezing of transparent and non transparent surfaces an electro-conductor, invisible to human eyes, as heater has been used to induce a thermodynamic transformation. In the case of defogging the liquid-gas thermodynamic transformation is induced. The solid-gas thermodynamic transformation is induced in the case of anti-freezing.
This invisible electro-conductor heater is made by a film of electro-conductive compound, it has a variable geometry, it is deposited on the quasi totality of the treated surface, it has a thickness variable depending on the specific case. depending on the treated surface chemical-physical properties. Sputtering, laser ablation, chemical evaporation, physical evaporation, plasma spray and any other technique can be used to make such kind of film. Of these, the only one working at room pressure and temperature on large surface area is plasma spraying. This is the application method claimed for this invention.
The deposited film pattern geometry, if any, is studied to have as high as possible the ratio R between the treated surface and the non treated surface. The limit is one when the treated surface is the totality of the surface. This ratio is important in the optimization of heating process and hence the defogging and/or anti-freezing effect. Moreover, the pattern geometry of deposited film, in a wide range of R, give the possibility to produce, during the defogging and /or anti freezing effect, any kind of logo design on the treated surface. In fact, the part of surface treated with the film will be defogged and/or de-freezed more rapidly that the one not treated, creating the effect of logo design on the surface.
The deposited film thickness can vary from a few A (10"10meter) to hundreds of micron, depending from the optical and physical properties that are requested for the particular application.
In figure 1 , there is the application for transparent surfaces, particularly on the car windshield where is possible to see a particular geometry (2) and electrical contact (1) made by transparent electro-conductor. In the case of car window, is possible to see the same application without geometry, the transparent electro-conductor is deposited homogeneously on the surface (2) and powered by the contact made by the same material (1 ). In order to avoid fog, ice and freezing that obstruct the vision.
In figure 2, there is another application for non transparent surfaces, particularly on the aircraft tail rudder (1) where the transparent electro-conductor is deposited as strip. Then the same application applied at the aircraft wing rudder (1). In order to avoid ice and freezing that obstruct the movement.
In figure 3, there is another application for non transparent surfaces, particularly on the aircraft nacelle(1 ), in this case the transparent electro-conductor is used to avoid ice flow in the turbine engine.
In figure 4, there is another application for transparent surfaces, particularly for the helmet windshield where the transparent electro-conductor is deposited with or without a geometry or simply homogeneously (1) on the surface in order to avoid fogging formation. anti-freezing.
Other examples of possible applications
• defogging and/or anti-freezing effect of the car windshield instead of the conventional forced air system. This system is more efficient especially when the car engine is cold.
• defogging and/or anti-freezing of the glasses window using the REI system. Particular application is on the glasses of anti-gas mask.
There are many application of this system, in particular anywhere defogging, anti- freezing and shielding effect is needed on a surface. The most important applications are in such surface where the optical transparency is needed.
