[0002] At present, the snow on the surface of solar components is often removed by manual work, which not only consumes a large amount of labor cost, but also has low efficiency. Especially when the snow covers the surface, the normal power generation of the solar components is affected due to the failure to remove the snow in time, which leads to the reduction of power generation benefit and high cost from the overall operation point of view. The defogging method commonly used for the front windshield of a vehicle is blowing, which has a dead angle due to the position of the air outlet and the wind direction, cannot effectively remove the fog, and the presence of water vapor also affects the vision to some extent during the defogging process, which cannot achieve the ideal clear vision effect.
[0003] The existing surface defogging technology cannot simultaneously meet the requirements of the key indicators of appearance, cost control and defogging effect. Either the appearance is poor, or the cost is too high, or the defogging has defects, which cannot adapt to the diversified needs of surface defogging and snow removal scenes, such as the front windshield of a vehicle, the surface of a solar cell component, and curtain wall glass. The appearance, cost and effect of the defogging film are highly expected, and the existing technology has obvious shortcomings in these aspects.
[0004] The heating method of the electric heating wire and the silver line has the problems of poor appearance and low transparency. These heating elements are directly laid on the surface to be defogged, which affects the overall visual effect of the appearance, and the presence of the heating elements reduces the transparency of the covered area, affects the vision or the original display effect of the object. Therefore, we propose a transparent defogging film. CONTENT OF THE UTILITY MODEL
