What are the advantages of PTC heaters for new energy vehicles
Benefits of PTC heaters
1. Self-constant temperature, double reliable.
In recent years, the heating wire should use iron-chromium-aluminum alloy and nickel-chromium alloy, and its high temperature can reach 1400 °C, so the heating wire relies heavily on the temperature control system in the application to prevent the air duct from melting due to overheating.
However, the fever temperature of PTC ceramic PTC for electric vehicles is limited by the living temperature, and it is suitable for low-temperature heating platforms with low power below 300°C. The Curie temperature of PTC sheet (40~300 °C) can be selected according to user requirements.
2. New material, double health.
In the heating process, the heating of the heating wire is accompanied by the luminescence process, resulting in inevitable light and oxygen consumption, and emission of exhaust gas, nickel-chromium alloy contains beryllium, which is carcinogenic. In addition, nickel is also carcinogenic and carcinogenic to the human body, such as porcelain teeth (containing nickel) is not beneficial to the kidneys.
And the company's electric vehicle PTC heater PTC products, fever does not emit light, no open flame, light oxygen consumption, no waste gas generation, harmless to the human body.
3. Self-saving, more power saving.
The electrothermal conversion rate of the heating wire is low (about 60-70 percent), while the PTC electrothermal conversion obedience is relatively high, reaching more than 99 percent, and there is almost no energy loss, so the thermal obedience is greatly improved (quoted from China Electronics News), so our electric vehicle PTC heater fan is higher than the ordinary PTC electric thermal conversion obedience, and the thermal obedience is greatly improved (quoted from China Electronic News).
4. Working hours are 41,000 hours.
Generally speaking, the surface of the heating wire is oxidized, the oxidation is uneven, the heating wire part becomes thinner, the resistance rises, the temperature also rises, the oxidation rate is accelerated, the resistance rises further, and the heating wire breaks rapidly. Life once ended. According to statistics, under the rated voltage and power, there is a life within 72 hours of work.
But the low-speed electric vehicle PTC heater produced by our company can work continuously for 1,000 hours, and the PTC application life can reach more than 100,000 hours.
5. Insulation disposal, not affected by the outside world.
In order to prevent short circuits, heating wires are very demanding and need to remove iron and silicon carbide before installation. These components are damaged during installation and transportation, and their service life is also reduced. The heating wire emits light when heated. Dust entering the heater location from the air duct of an electric vehicle's air conditioner can provoke open flames and incineration.
