The heating element used in the normal oven is usually dry heating element. And the most common use of dry heating element is the finned electric heating element. Fin type electric heating element is different from the conventional electric heating pipe is that it has a heat sink, the heat sink plays the role of heat dissipation, so that the surface temperature of the heating tube is not high, so that the life of the heating tube is prolonged. (We have talked about this before, dry burning heating pipe generally has temperature control).
Finned type heating element generally can be classified into spiral wound finned tubes and the square finned element, appearance is different, there is a big difference of its cooling effect, square finned heating element's heat dissipation effect is significantly better than winding type finned tube is much better, but, in contrast, square finned heating tube cost will be much higher, Ultimately, it depends on the customer's choice.
