How fast does a PTC heater age?
PTC heater heating up quickly, in case of fan failure can also self-control the temperature, long service life, voltage use is wide, can be planned between 12V-380V according to demand, planning is convenient, can be planned from small power to high power arbitrarily, the shape can also be planned according to requirements, no incineration, safe and reliable, PTC fever does not red, no open flame. In small and medium-power heating places, PTC heating has a constant temperature fever, no open flame, high thermal conversion rate, minimal influence by the power supply voltage, long natural life and other ancient fever components cannot be compared, and the use in electric heating appliances is more and more favored by R&D engineers.
Aging attenuation is one of the key parameters to weigh the quality of PTC heater heater, the first 400 hours of use aging rate is faster, and then gradually eased, after 1000 hours of continuous work, the output power of good components is about 10% attenuation, and the high temperature fan then tends to be stable, which has little impact on the heating effect of the heater. As the room temperature rises, the output power slowly falls, and the heating effect becomes more dull.
The high power density is also one of the distinctive features of the heater. However, with the passage of time, the aging decay is very obvious. PTC heater heater uses forced convection to heat the room temperature, because the heat transfer coefficient of forced convection air is dozens of times that of natural convection, so the heat exchange area required to transfer the same heat is as small as one-tenth, and a 100-120W component can be made to a small volume of 24×15×2.2 mm3, which is exactly the same power environment. Pneumatic ball valve affects the aging attenuation of many factors, the Curie point is high is its important reason, the higher the Curie point, the faster the aging, some miscellaneous manufacturers for the sake of saving about the old capital and one-sided pursuit of high power, often choose TC≥260 °C components to make fever heater in the early stage of use as if there is no PTC heater heater can be done delicate and simple links.
