PTC heater sub-heating principle:
1. PTC ceramic heater based on heat conduction. Its characteristic is that the electrode plate (electrical conductivity and heat transfer) and insulating layer (electrical insulation and heat transfer) are installed on the surface of the PTC heating element. Glue) and other multi-layer heat transfer structure to transfer the heat emitted by the PTC element to the heated object.
2. Various PTC ceramic hot air heaters that use the formed hot air to conduct convective heat transfer. It is characterized by large output power, and can automatically adjust the blowing air temperature and output heat.
Infrared radiant heater. Its characteristics actually use the heat from the surface of the PTC element or the heat-conducting plate to directly or indirectly stimulate the far-infrared paint or far-infrared material that touches its surface to radiate infrared rays, which constitutes a PTC ceramic infrared radiant heater. .
3. PTC is an abbreviation for ceramic heating element. It uses a fan to blow air through the PTC electric heating element to force convection, which is the main heat exchange method. It is equipped with a temperature limiter inside, when the air outlet is blocked by the fan, it can automatically cut off the power. Some are also equipped with a dump switch, which can automatically cut off the power when the heater is dumped. Its output power is 800-1200 watts, and the temperature can be adjusted at will. The air supply is soft during work, the temperature rises quickly, and it has an automatic constant temperature function. The PTC components are generally waterproof, so they are suitable for use in the bathroom. The price is between 300 and 500 yuan. It is an ideal portable household electric heater.
