Characteristics and working principle of electric heater made of cast aluminium

The electric heater is cast aluminum tubular electric heating element for heating body, with high quality casting materials for electric heater shell by casting, the use of temperature between 150 degrees Celsius to 450 degrees, can be widely used in plastic machinery, die head, cable machinery, chemical, rubber, oil and other equipment. The cast aluminum heater has the advantages of long life, good thermal insulation, strong mechanical performance, corrosion resistance, and resistance to magnetic fields.

The cast aluminum electric heater is a kind of high efficiency, hot and uniform heater. It has excellent thermal conductivity. It ensures the uniform temperature of the hot surface and eliminates the hot spots and cold spots of the equipment. The utility model has the advantages of long life, good heat preservation performance, strong mechanical performance, corrosion resistance, and resistance to magnetic field, etc.. The external heat radiation surface is added with an insulation device, and the inner heat radiating surface is sintered with infrared rays, thus saving electricity consumption 35%. Cast aluminium electric heater is one kind of electric heater.

The electric heater varieties include: cast iron, cast aluminum heater heater, quartz tube heater, stainless steel electric heating pipe, heating pipe, the 10 steel belt winding fin heating tube, VC443, VC442, VC441, VC432 induction heater, hot plate assembly, vacuum diffusion pump electric heating plate, dust-free heater, thermocouple, wire, high temperature ceramics heating tile, resistance wires of various specifications.

Usage and maintenance:

1， First, check whether the on-site power supply voltage is in line with the rated voltage of the product. If different, the same supply voltage as the rated voltage of the product shall be supplied.

2, in order to ensure safety, remember that the power equipment should be reliable grounding.

3, the electric heater products exist for more than three months, and then use, should be allowed in the condition of intermittent, self drying, heating ten minutes, power failure for half an hour, continuous three to four times in order to discharge the internal humidity of the electric heating element.

4, electric heaters during storage should pay attention to moisture corrosion, stored in a well ventilated place.

The electric heater is cast in a seamless metal pipe arranged in the electric wire, the void fill has good thermal conductivity and insulation of magnesium oxide powder after the pipe and then processed into various shapes required by the user. The utility model has the advantages of simple structure, high thermal efficiency, good mechanical strength, good adaptability to bad environment, etc.. The product can be used for heating various liquids and salts of acids and bases, as well as for melting and melting of metals of low melting point.

We often know Home heater is an electric heater do, electricity can be hot water. In fact, now many industries in the cast aluminum heater, widely used in power plants, oil refineries, oil, chemical, military, aerospace and other industries.

Aluminum electric heating equipment is a tubular electric heating element, heating has the advantages of convenient use, convenient installation, no pollution, is widely used in various heating occasions, there are a lot of the production of electric components manufacturers, there are many brands of products. Product life is very long, the general design life of more than 10000 hours, and some far infrared radiation heating element, can have 5 heating seasons life.

The cast aluminum electric heater is more suitable for the heating place of antifouling. It is the best choice for rust prevention and anti fouling. It is the best choice for rust prevention and anti fouling. Meanwhile, it can greatly reduce acid consumption, energy consumption, production of waste liquid and improve working conditions, and is conducive to environmental protection.

Aluminum electric heating equipment is a metal tube shell, along the tube axis to uniform spiral electric heating wire (Ni Cr, Fe Cr alloy) the gap filling compaction with good insulation thermal conductivity magnesia, pipe ends are sealed by silica gel, the metal sheathed heating element to heat the air, mold and all kinds of liquid metal.

The electric heater is cast in the heating element in a metal pipe, and the gap part tightly filled with good heat resistance, thermal conductivity and dielectric properties of crystalline magnesium oxide powder, in other treatment the. The utility model has the advantages of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, simple installation and long service life, etc..
