Vehicle-mounted warm air defrosting system: most of automobile front window defrosting devices adopt a method that hot air of a warm air device blows to glass to achieve the aim of defrosting. It is composed of blower, hot air inlet and outlet pipes and defrosting nozzle. The defroster nozzle is installed in the lower part of the windshield, and the length of the nozzle accounts for about 2/3 of the half side of the windshield. Defrosting the electric heating glass with the resistance wire: the principle of defrosting the electric heating glass is that a plurality of heating resistance wires are uniformly arranged in the windshield, after a resistance switch is turned on, the resistance wires heat the glass at a high speed, so that the temperature of the glass is increased, and frost attached to the glass is heated and melted, thereby achieving the defrosting effect. The disadvantages are that: because the opacity of resistance wire can influence driver's sight, causes the hidden danger to safe driving, so can not install on car front windshield, this kind of defrosting mode is more applied on car rear windshield at present.

The two defrosting modes are complex in design and require professional design of a defrosting system, a control strategy and a corresponding matching structure. Structural design, control system, installation, manufacturing cost are high, and it is inconvenient to maintain.
