Analysis of working principle of defrosting heating tube

First, the structure of defrost heating tube

The defrosting heating tube is composed of multiple strands of pure nickel resistance wire, which becomes a tubular electric heating element after three-dimensional interweaving. There is a insulation layer on the outside of the tube body, and the insulation layer is covered with a skin. In addition, the defrost heater is also equipped with a wire and insulation sleeve to facilitate the wiring between the power supply and the defrosting heating tube.

Second, the principle of defrost heater

Tubular defrost heater is a defrosting heater using the principle of resistance heating, which can automatically heat at low temperatures to prevent frost and freezing. When the water vapor in the air condenses on the surface of the equipment, the defrosting heater tube will be powered by the power supply, and the resistance heating will increase the temperature around the tube body, thereby melting frost and accelerating evaporation, so that frost can be eliminated.

Third, the application scenario of defrosting heating pipe

Defrost heating tubes are widely used in refrigeration systems, air conditioning systems, cold storage and other places to help equipment heat dissipation, prevent freezing and frost. At the same time, the defrosting heating pipe can also be used in low-temperature process equipment, such as metallurgy, chemical, pharmaceutical and other industries, to ensure the normal work of the equipment at the same time, but also to ensure the energy-saving operation of the equipment in the low-temperature environment.

Four, the advantage of stainless stell defrost tube heater

Due to the advantages of small size, simple structure, fast heating, low energy consumption and long life, defrosting heating tube has been widely used in many fields. At the same time, the use of defrosting heating pipe is also conducive to reducing the maintenance cost of equipment and improving the reliability of equipment, bringing actual economic benefits to industry users.

【 Conclusion 】

Defrosting heating tube is an advanced and efficient heater for cryogenic equipment in a variety of industries, helping to prevent freezing and frosting and improving the efficiency and reliability of equipment operation. It is hoped that the working principle of defrosting heating tube introduced in this article can be helpful to readers.
