The basic principle and function of PTC heater PTC type ceramic heater is made of PTC porcelain hot parts and wavy aluminum plate through high temperature viscose. This type of ptc electric heater has the advantages of small heat transfer coefficient and high heat exchange efficiency. It is a fully automatic temperature control and power saving electric heating device. One of its prominent characteristics depends on the safety factor. Under all operating conditions, it is not easy to cause the surface "redness" of the heating tube electric heater, which will cause burns, fire accidents and other full risks. The obvious characteristics are: PTC type ceramic heater saves costs and has a long life. The professional temperature controller and thermal resistance thermal resistance and other temperature sensors can carry out the hot operation of the electric heater through the temperature feedback. The service life of the water heater. PTC type ceramic heater is safe, low-carbon and environmentally friendly. The design scheme of the electric heater itself has a heating temperature of multiple levels below 200 degrees Celsius. Under all conditions, it is not reddened and has a maintenance protection layer. All applications do not require asbestos and other heat insulation materials to cool down, and can be used with confidence There is no problem of scalding the human body and causing fire. The PTC ceramic heater saves electric energy.
The higher the surface temperature of the PTC, the higher the power. Pay attention to the use of ptc electric heater. The PTC heater has the characteristics of automatic constant temperature. It does not require a temperature control system. It can be powered directly. When the positive temperature coefficient heating element is used to heat the liquid (such as water), the positive temperature coefficient heating element will not be damaged after the liquid is dried. If the positive temperature coefficient heater is used to heat cold air, when there is no air supply, the high temperature fan positive temperature coefficient heater will not be damaged. The service life is long, up to more than 10 years under normal conditions. Reliable operation, using the internal characteristics of the PTC heater for temperature control, over-temperature. Working voltage non-constant width: When the working voltage changes twice, the surface temperature changes very little. When multiple PTC heating panels are used together, they should be connected in parallel, not in series. Different heat dissipation conditions make the heating power of the PTC heater vary greatly. The heating power is stable from high to low after energization. The stable power is related to the use conditions. For the same PTC heater with different use conditions, the power may differ several times. The electric heater has fast thermal response, high temperature control accuracy, and high comprehensive thermal efficiency.
