Electric heated glass, also known as anti-fog glass, defogging glass, is a special glass that is heated to achieve defogging and defrosting after being powered on. Therefore, electric heated glass is widely used in display cabinets, freezers, refrigerators, cold storages, aircraft windows, high-end cars, doors and windows in cold areas, etc.
Electric Heated Glass Working principle
Electric heated glass uses an electric current to pass through a heating element to generate heat, thereby increasing the surface temperature of the glass. When current passes through the heating element, the heating element will generate Joule heat, which will increase the temperature of the glass substrate, and then the water on the glass surface will gradually evaporate after being heated, achieving the effect of defogging. At the same time, the glass surface can be maintained at 30~50℃ when electricity is supplied, keeping the temperature constant for a long time. Electric heated glass can also achieve temperature control in different areas by controlling the current and the distribution of heating elements to meet different application needs.
Electric Heated Glass Features
