1. How the heater works
Using an alternating magnetic field, a primary coil with more turns and a secondary coil with fewer turns are mounted on the same iron core. In this way, the voltage ratio of input and output is equal to the ratio of coil turns, while the energy remains unchanged. Therefore, the secondary coil will generate a large current under low voltage conditions, thereby generating a large amount of heat for heating.
2. How to keep the air heater performing well?
We start from three aspects to achieve the goal, specifically:
1）Increasing the gas inlet flow rate of the air heater can strengthen the convection heat transfer of the air heater, thereby reducing the surface temperature of the electric heating element in the air heater, which not only helps to prolong the service life of the electric heating element of the air heater, but also reduces the air Heat dissipation loss of the heater, but pay attention to the speed not too large, but it will have the opposite effect.
2） Change the surface load with other conditions unchanged. But it should be noted that if the surface load is too large, the wall temperature of the electric heating element will increase, which will reduce the service life of the electric heating element in the air heater. If the surface load is too small, the wall temperature will be too low, but it will decrease The heat exchange effect of the air heater, so the selection should be appropriate.
3） Raising the final temperature of the air in the air heater has a certain effect, but it cannot be increased too much, because when the final temperature is increased too much, the temperature of the surface of the electric heating element will also be greatly increased, making the general electric heating element unbearable. Consider the limitation of heat resistance of electric heating element materials in air heaters.
