Right!

The electric heating element is a component that converts electrical energy into thermal energy and is the heart of an electric heater.

According to its structure, it is divided into two categories: single electric heating element and composite electric heating element: single electric heating element is composed of one material; composite electric heating element is composed of several materials.

According to the different materials, it can be divided into metal electric heating elements and non-metal electric heating elements: metal electric heating elements such as nickel-chromium wire (Ni-Cr), iron-chromium-aluminum wire (Fe-Cr-Al), nickel-iron wire (Ni-Fe ), Nickel-copper wire (Ni-Cu)), etc .; non-metallic electric heating elements include silicon carbide, silicon molybdenum rods, PTC electric heating elements, electric heating coatings, etc.

According to its shape, it can be divided into metal tube, quartz tube, ceramic tube, plate, square, oval, round, ceramic coated electric heating element and so on.

The metal tubular electric heating element is referred to as an electric heating tube, which is a sealed electric heating element that is widely used in all electric heating elements, has a simple structure, reliable performance, and a long service life.

As early as the 1930s, the British company Hot Point applied metal tubular electric heating elements to household appliances. At present, electric heating pipes have been widely used in the injection molding industry, chemical industry, auxiliary heating and other industries and household electric ovens, vertical air conditioners and other electrical appliances at home and abroad. In order to further improve thermal efficiency, many domestic manufacturers have produced a large number of finned electric heating tubes for the market.
