The design and production of open electric air conditioner heater meet the requirements of light weight design. Except for the special wire winding method different from the electric heating tube, the open type electric heater has no structure and shape of the electric heating tube at all. There is no processing of the production of the electric heating tube, and there is no powdering, shrinking, winding, and aging More than 10 processes. Therefore, the production cycle of the open type electric heating element is greatly shortened.
The open type electric air conditioner heater uses only a few galvanized or mica plates and flexible heating Wire, without the use of stainless steel tubes and stainless steel bands and fixed or supported copper fastening. It saves a lot of metal materials and greatly reduces the weight. The increase in the price of copper and nickel has little effect on the cost of bare electric heating elements. At the same time, in the production process of bare electric heating elements, there is no MgO powder and sand blasting process used for tubular electric heating elements, which directly reduces dust emissions.
The open type air heater make the heating wire to hear the flowing air directly, this achieves the faster heating and higher heating transfer efficiency.
