With the increasing demand in the electric heating market, automatic electric heating devices composed of thermistors, heating elements, temperature control switches, and more, have been widely used in various fields. However, the combination of these products that have already been applied in different domains has not yet been seen in the market. Danyu heating elements have made new improvements to existing technologies to not only address heating issues but also solve safety challenges in their application. The outlook for this technology is very promising.
Transparent heating elements, also known as Thin Film heaters, are devices that heat up and warm when electrified, achieving defogging and defrosting. Transparent heating elements find extensive applications in display cabinets, showcases, refrigerators, freezers, cold storage rooms, environmental test chambers, constant temperature and humidity chambers, high and low-temperature impact chambers, high-end villas, marine windows, aircraft windows, high-end automobiles, doors, and windows in cold regions, and any place where defogging is required.
The manufacturing process of transparent heating elements involves laminating two or more pieces of tempered glass using PVB or specialized adhesive film. Between the transparent film layers, extremely fine metal heating wires are embedded on one side of the film, which heats up rapidly when electrified. The heating element itself possesses a positive temperature coefficient (PTC) thermistor, which is connected to a temperature control system, enabling automatic temperature regulation of the glass surface. It also offers a certain level of impact resistance and safety. The glass surface temperature can reach up to 90°C, and the transparency can reach 90%.
Effective Frost and Dew Removal: Transparent heating elements, when electrified, raise the surface temperature (typically up to 90°C), preventing frost and condensation on the glass surface. The voltage is safe and poses no harm to humans.
Excellent Optical Performance: Transparent heating elements use conductive wires or films as heating media, ensuring good light transmittance and anti-distortion performance of the glass, allowing clear and accurate visibility through the glass.
High Safety: The tempered glass used in the sandwich structure of transparent heating elements has high hardness and is not easily shattered. Even under the impact of gravity, glass fragments will remain adhered due to an organic film, preventing them from scattering and causing harm.
Heating principle: The principle of the transparent heating plate is that after energizing, its surface temperature rises after about 10 minutes, and the temperature rise ranges from -40°C to 100°C, so that the surface temperature of the heating plate is flat or slightly higher than the surface temperature of the heating plate, and then reaches The heating effect within the working environment temperature range of the product can achieve no fog and frost. The transparent heating sheet has the advantages of low voltage, low power consumption, and safety.
The transparent ITO heater is a visually transparent substrate. The transparent PET material has high temperature resistance and is coated with conductive indium tin oxide with different sheet resistance. When current is passed through this coating, it generates the required heat while quickly raising the temperature to prolong the operating temperature of liquid crystal displays (LCDs) in cold environments, and to defog, de-ice and anti-ice optical displays/ The role of optics.
