Heating plate classification
Date of publication：2019-07-11

Heating plate is a kind of safe and reliable electric heating plate with circular or square shape, which is heated by electricity but has no electricity and no flame. Because the main use of heat conduction, so high thermal efficiency.

There are five types of electric heating plates: thin shell type, carbon crystal electric heating plate type, cast plate type, tubular element type and tubular element cast plate type.

Thin shell heating plate

Thin shell electric heating plate is embedded with spiral electric heating wire in the shell formed by metal sheet stamping. This kind of metal thin shell type structure is simple, the price is cheap, but the plate surface is easy to deform, after long time use the thermal efficiency has the decline phenomenon, therefore generally makes the 800W below the small power electric heating plate.

Carbon crystal electric heating plate

Carbon crystal electric heating plate is a kind of electric heating plate with carbon crystal material as the theme of heating material. A plate-like heating material without a heating wire and without a metal shell. Mainly by adding an electric field to the plate, the molecules inside the plate friction heat; Therefore, the safety factor of carbon crystal electric heating plate is higher, and there is no possibility of electric leakage. Carbon crystal electric heating plate is a new type of heating plate with better flexibility than other types of electric heating plate.

Cast plate heating plate

The structure of cast plate heating plate is the same as that of thin shell heating plate, except that the plate surface is cast metal, so the strength is large and the plate surface is not easy to deform. Tubular element heating plate is a heating plate formed by bending the tubular metal heating element into a plane spiral involute. This kind of tubular metal heating element is a semicircular section with a flat surface. Such a section makes a larger heat transfer surface between the heating plate and the bottom of the cooking pot, so as to improve the thermal efficiency.

Tube element cast plate type

Cast plate heating plate is a complete electric heating plate made of si-al alloy or si-cu alloy after the tubular heating element is bent into the shape of 1 ~ 5 rings. Compared with tubular element heating plate, it has a larger effective heat transfer surface with the bottom of the pot. This kind of structure has big mechanical strength, long life and high thermal efficiency, which is especially suitable for ships, vehicles and other vibrating environments.
