How Is The Heating Fan Made By PTC Electric Heater Heated
- Oct 25, 2018 -

PTC electric heater heater by way of forced convection heating room temperature, because of the forced convection heat transfer coefficient of air natural convection is dozens of times, so the heat transfer also the required heat exchange area of a small percentage to small, a 100-120 w PTC electric heater components can be 24 x 15 x 2.2 mm3 in such a small volume, which is the same power, PTC heater electric heater can be the key to doing small and light, with its volume and weight can be small to power electric heating oil heater around one 5.Aging attenuation measure PTC electric heater is one of the main parameters of heater's quality, PTC electric heater elements used 400 hours before the fastest aging, increasingly flat and then, after 1000 hours continuous work, good PTC electric heater element output power attenuation about 10% or so, then leveled off, the PTC heater electric heater heating function.There are many factors influencing the aging attenuation of PTC electric heaters, and the high Curie point is the main reason. The higher Curie point, the faster aging, but the aging attenuation is obvious over time.
