Because of the advent of electricity, there will be many great inventions that affect the future, Edison's electric light needs electricity to shine, Bell's invention of the telephone needs electricity to talk, and John's invention of the television set needs electricity to watch programs. Many products around us are powered by electricity, and many products have heaters in them, of course, heaters are also powered by electricity. There are many kinds of electric heaters we use, and today I will introduce you to PTC electric heaters.
Introduction to PTC heaters
PTC type ceramic heater is composed of PTC ceramic heating component and corrugated aluminum strip by high-temperature gluing. This type of PTC heater has the advantages of small thermal resistance and high heat exchange efficiency, and is an automatic constant temperature and power-saving electric heater. One of its outstanding features lies in the safety performance, and in any application, the surface "redness" phenomenon of electric heating tube heaters will not occur, resulting in scalds, fires and other safety hazards.
PTC electric heater features
1. PTC type ceramic heater saves cost and long life.
Temperature feedback can be carried out on the heater without special temperature sensors such as thermostats and thermal resistance thermocouples, and its temperature regulation is based on its own material characteristics, so that the product has a service life much greater than other heaters.
2. PTC type ceramic heater is safe and environmentally friendly.
The heater body is designed to heat multiple grades below 200 degrees Celsius, in any case
The body is not reddened and has a protective isolation layer, and no thermal insulation materials such as asbestos are required for any application
Cooling treatment, can be used with confidence, there is no problem of scalding the human body and causing fire.
3. PTC ceramic heater saves electric energy.
PTC electric heater use caution
(1) PTC heating discs feature automatic constant temperature, no temperature control system is required, PTC heating discs can be directly energized.
(2) When the PTC heating sheet is used to heat a liquid (such as water), the PTC heating sheet will not be damaged after the liquid is burned dry.
(3) If the PTC heating sheet is used to heat cold air, the PTC heating sheet will not be damaged when there is no air supply.
(5) Long service life, used in normal environment, life can reach more than 10 years.
(6) Reliable work, using the internal characteristics of PTC heating sheet to control the temperature, will never overtemperature.
(7) The working voltage is very wide: when the working voltage changes by 2 times, the change in surface temperature is very small.
(9) When multiple PTC heating plates are used together, they should be connected in parallel and not in series.
