PTC HeaterIt is an automatic constant temperature energy-saving electric heater. Its outstanding feature is good safety performance. It will not produce the "reddening" phenomenon on the surface of electric heaters and other heaters, causing safety hazards such as burns and fires. The relationship between the heating power and heating time of PTC heaters is very different from that of traditional heaters.

At the start of heating,PTC HeaterThe power gradually decreases from small to large, and then gradually decreases to stable after reaching the peak pulse power. The stable power of dry burning is much less than boiling water. The stable power depends on the type of liquid. When the liquid is water, the power is larger, because water has better fluidity, larger specific heat capacity, and is easy to form convection. The stable power of heating other liquids is generally less than water. The higher the dry burning surface temperature of the PTC heater, the greater the stable power. However, the increase in surface temperature will increase the chance of PTC heating sheet breakdown, and the performance of viscose, wire, insulation layer, etc. will deteriorate, and the reliability will decrease. When the surface temperature of the PTC heater is the same as the liquid temperature, the heating power is basically 0, that is, no more heating. Therefore, the dry burning surface temperature of the PTC heater will always be more than 20°C higher than the liquid temperature, otherwise it cannot be heated. The smaller the difference between the surface temperature of the PTC heater and the liquid temperature, the smaller the power density, the larger the volume, and the higher the cost.

PTC HeaterIt heats up quickly and is conveniently designed. It can be used in any power range, and the safety risks are relatively small.
