Compared with the ancient electric heating tube, the PTC heater has the following advantages, let me talk about three points:
1. Safe and timely when the fan fails to stop or stall, the surface temperature of the heater at this time maintains a limited safe temperature around (usually 230 °C), so as not to produce signs of surface "redness" and eliminate the disorder. Hidden dangers.
2. Energy saving. When the temperature of the situation rises, the resistance of itself will gradually increase, and the power will gradually drop. After the temperature of the situation is consolidated, the power will stop changing, so as to achieve the effect of energy saving.
3. High heat conversion rate and long lifespan, with minimal influence from external voltage. PTC heaters are superior to traditional electric heating tubes in all aspects of performance through careful planning.
PTC reason: PTC heater manufacturer is a kind of heater with automatic temperature control and power saving. Therefore, PTC thermal ceramic element is the source of fever, and the corrugated sheet made of aluminum alloy is used as the radiator, which is formed by bonding and welding. Fever.
The high temperature resistance wire is uniformly diffused 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. There is a current passing period in the high-temperature resistance wire, and the heat generated is dispersed 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.
benefit:
1. The heating temperature is below 200 degrees Celsius
2. The main body will not be red under any circumstances, and there is a protective cut-off layer.
3. Strong planability, rapid production, and high degree of mechanization
4. There is no problem of burns and anger to the human body
5. It is convenient to plan and control the control cabinet
harm
1. Large impulse current
2. The heating temperature is high and can reach 600 degrees or so
3. The measurement of power has high requirements for the situation
4. High thermal inertia of temperature
5. The production of the old book is higher than the electric heating tube
6. The degree of mechanization is not high, and the production is subject to inevitable restrictions
The surface of the automobile PTC heater is electrified. Human body contact may cause electric shock.
After permanent application, the stored dust and impurities can easily cause a short circuit between the two poles and cause a fire.
The surface of the heater is electrified, and its waterproof and moisture-proof function is poor. Water splashing on the surface of the heater will cause electric shock and cause a short circuit of the heater.
The heater is insulated, the surface is not charged, and human contact will not cause electric shock.
After permanent application, the stored dust and impurities will not cause a short circuit and will not cause a fire
The heater is insulated, with a waterproof plan, and good waterproof and moisture-proof performance. Water splashing on the surface of the heater will not cause electric shock and cause short circuit destruction of the heater.
