PTC HeaterThe relationship between heating power and heating time is very different from that of traditional electric heating wire heaters.PTC HeaterThe power increases from small to large, reaches a peak, then gradually decreases and then tends to be stable.

The stable power depends on the type of liquid. When the liquid is water, the power is higher because water has a larger specific heat capacity, better fluidity, and is easy to form convection. The stable power of heating other liquids is generally less than that of water.PTC HeaterThe higher the dry combustion surface temperature, the greater the stable power. However, the increase in surface temperature will lead to increased power attenuation, increased chances of PTC heating sheet breakdown, degradation of the performance of adhesives, wires, insulation layers, etc., and reduced reliability. 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 combustion surface temperature of the PTC heater will always be more than 20°C higher than the liquid temperature, otherwise it will not 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. The greater the impact power of the heater, the greater the stable power is not necessarily. If the impact power is too large, it will affect the normal operation of the power circuit and switch, but if the impact power is too small, the stable power will not meet the requirements.

PTC heaters heat up quickly, have a long service life, and are easy to design. They can be used in any power range, and the safety risks are relatively small.
