Several factors affecting the relationship between flange electric heaters

Several factors affecting the relationship between flange electric heaters

1. Increasing the gas inlet flow rate of the flange electric heater can enhance the convection heat transfer of the flange electric heater and reduce the surface temperature of the electric heating element in the flange electric heater. This not only helps extend the service life of the electric heating element of the flange electric heater, but also reduces the heat loss of the flange electric heater. Therefore, the power of the air heat exchanger is increased. However, if the speed is too high, the pressure loss will increase sharply, which will not be conducive to the improvement of heating power.

2. If other conditions remain unchanged and the surface load is changed, the wall temperature of the electric heating element in the flange electric heater will change linearly. If the surface load increases, the wall temperature of the electric heating element will increase, which will reduce the service life of the electric heating element in the flange electric heater. However, if the surface load is too small and the wall temperature is too low, the power of the heat exchanger of the flange electric heater will decrease, so the selection of the surface load of the electric heating element in the flange electric heater is more important.

3. When the final air temperature T2 in the flange electric heater increases, because the air viscosity increases and the gas Reynolds number decreases, the convective heat transfer intensity decreases. The surface temperature of the electric heating element in the flange electric heater rises at the same time, which increases the heat dissipation loss, thereby reducing the efficiency of the heat exchanger.
