The Air conditioner auxiliary open coil heater made by Jaye industry is a exposed electric heating element with simple structure, high efficiency, energy saving and light weight.
The open coil heater includes a metal frame, and a long and narrow electric heating conductor is arranged in the metal frame, the entire electric heating conductor is bent into multiple segments connected to each other, and the electric heating conductor is in the shape of a ribbon or a spiral wire. It is fixed on the metal frame by insulation.
Each section of electric heating conductor can be located in the same installation plane to form a flat structure; the spiral wire-shaped electric heating conductor is bent into multiple sections, The porcelain block and the insulating porcelain block are respectively fixed on several mica boards, and then fixed on the metal frame through the mica board, and the insulating porcelain block and the mica board together form an insulating piece for fixing the electric heating conductor. The metal frame is also installed with a thermostat and a fuse connected to the electric heating conductor.
Since the electric heating conductor is in direct contact with the heating medium (such as air), there is no unnecessary heat conduction path, which eliminates the heat conduction loss in the structure, thereby improving the heating efficiency. At the same time, the structure is simple, the manufacturing is convenient, the insulation is reliable, the installation is easy, and the safety is good.
