Advantages and disadvantages of PTC ceramic heating element
PTC ceramic heating element is a thermistor, which is composed of PTC ceramic heating element and aluminum tube. It has the advantages of small thermal resistance and high heat exchange efficiency. It is an automatic constant temperature and power-saving electric heater.
Structural principle: PTC ceramic heating element is a kind of ceramic heating element with positive temperature coefficient and self-control temperature, which is sintered at high temperature.
Main advantages: the surface temperature of PTC Ceramic Heater can be controlled and kept constant, which can prevent dry burning
Main disadvantages: 1. PTC ceramic heating element has its own surface charged, which needs to be installed in a special heat dissipation component after surface insulation treatment, which increases the assembly cost; 2. The heat loss of the product and the heated object in the process of indirect heating leads to the reduction of thermal efficiency; 3. The power of PTC ceramic heater will gradually decline with the increase of working time; 4. The lead content of the product does not meet the environmental protection requirements.
