The difference between PTC heater and traditional heating element

The difference between PTC heater and traditional heating element

Compared with the traditional heating element, PTC heater has the following advantages

1 safety

When the fan is stopped or blocked in time due to a fan failure, the surface temperature of the heater will maintain a safety limit (usually 230°C), so as not to cause surface "redness" and eliminate the hidden danger of accidents.

2 energy saving

When the ambient temperature rises, its own resistance will gradually increase, and the power will gradually decrease, and the power will stop changing after the ambient temperature stabilizes, thus achieving the effect of energy saving.

3 High heat conversion rate

It has a long life and is less affected by external voltage.

PTC heater is superior to traditional heating element in all aspects of performance through careful design.

The difference between ptc electric heater and traditional heating element is as follows:

PTC heater is a kind of heater with automatic temperature control and power saving. It uses PTC thermal ceramic element as the heat source, the corrugated sheet made of aluminum alloy as the radiator, and the heater is formed by bonding and welding. We evenly distribute high-temperature resistance wires in high-temperature resistant stainless steel seamless tubes, and densely fill the gaps with crystalline magnesium oxide powder with good thermal conductivity and insulation properties. This structure is not only advanced, high thermal efficiency, but also generates uniform heat. When a current flows through the resistance wire, the heat generated is diffused to the surface of the metal tube through the crystalline magnesium oxide powder, and then transferred to the heated part or the air to achieve the purpose of heating.

advantage

1. The heating temperature is below 200 degrees Celsius

2. Low production cost

3. The body will not be red under any circumstances and has a protective isolation layer

4. Strong designability, fast production and high degree of mechanization

5. There is no problem of scalding human body and causing fire

6. Easy to design and control the control cabinet
