Comparison of PTC heater and traditional electric heating tube

Posted by Admin | 08 Dec

Compared with traditional electric heating tubes, PTC heaters have the following advantages:
1. Security
When the fan fails or is blocked in time, the surface temperature of the heater maintains a limited safe temperature (generally 230 ℃), so as not to produce surface "redness" phenomenon, eliminating the hidden danger of accidents.
2. Energy saving
When the ambient temperature rises, its own resistance gradually becomes larger, 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 minimally affected by external voltage. PTC heaters are superior to traditional electric heating tubes in all aspects of performance through careful design.
PTC principle: PTC electric heater is a kind of heater with automatic temperature control and power saving. It uses PTC thermal ceramic element as heat source, aluminum alloy corrugated sheet as radiator, and is composed by bonding and welding.的热器。 The heater.
The high temperature resistance wire is evenly distributed in the high temperature resistant stainless steel seamless tube, and the gap is densely filled with crystalline magnesium oxide powder with good thermal conductivity and insulation performance. This structure is not only advanced, high thermal efficiency, but also generates uniform heat. When there is an electric current in the wire, the heat generated is diffused to the surface of the metal pipe through the crystalline magnesium oxide powder, and then transferred to the heated part or the air to achieve the purpose of heating.
