The air duct type electric heater is mainly used for air heating in the air duct. The specifications are divided into three types: low temperature, medium temperature and high temperature. The common feature in the structure is that the electric heating pipe is supported by steel plates to reduce the vibration of the electric heating pipe. In the junction box All are equipped with over temperature control devices. In addition, in addition to over-temperature protection, an intermodal device is also installed between the "fan" and the "heater" to ensure that the electric heater must be started after the fan is started, and a differential pressure device is added before and after the heater. to prevent fan failure. The duct heater supports the electric heating pipe with steel plate to reduce the vibration of the electric heating pipe when the fan is stopped. Over-temperature control devices are installed in the terminal strip. The low temperature type can be directly installed on the air duct. Because the structure of the medium temperature type and the high temperature type is different, a 100 mm thick insulation material is provided from the outer wall of the channel to the heater wiring, which reduces the external heat dissipation of the entire channel on the one hand. On the other hand, the temperature in the wiring compartment is also reduced.
