PTC heaters use electric heating, especially in the manufacture of single crystals and transistors, mechanical parts and surface quenching, smelting of ferroalloys and the manufacture of artificial graphite. The selection of power is to meet the calorific value required by the heating medium, and is the first choice to ensure that the heater can achieve the purpose of heating and operate normally.
Electric heater Since the thermal efficiency of electric heating is similar, it can be considered that the power of the high-temperature fan electric heater is the calorific value. The 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, the heat exchange area required to transfer the same heat can be as small as several tenths. The PTC heater assembly can achieve such a small volume, which is the key to making the PTC heater heater small and light under the same power condition. The volume and weight of the frpp tube can be as small as five points of the same power electric heating oil heater. one or so. Aging decay is one of the most important parameters to measure the quality of PTC heater heaters. The aging speed of PTC heater elements is the fastest in the first 400 hours of use, and then becomes more gradual, after 1000 hours of continuous operation.
