Overview of electrical trace heating technology

　　Electric trace heat technology is a kind of heating technology that transfers heat energy to equipment, pipelines or surfaces through electric energy. It is widely used in many fields, such as construction, industry, medicine, food, metallurgy and so on. This article will introduce in detail the basic principle, practical application, advantages and future prospects of electric heat tracing technology.

　　The electric accompanying heat system usually consists of power supply, electric accompanying heat wire, control system and heat preservation layer and other parts. Power supply provides electric energy, electric accompanying heat conductor is responsible for transforming electric energy into heat energy, control system is used to regulate and control the heating process, and heat preservation layer is used to reduce heat loss and improve heating efficiency.

　　Second, the actual application of electric accompanying heat technology

　　1. Building field

　　In the field of construction, the electric accompanying heat technology is widely used in the ground heating, roof snow melting and frost prevention and so on. Ground heating is a kind of heating method with high energy efficiency, safety and reliability, which adopts heat-conducting material and electric accompanying hot wire to match and use, and transfers the ground heat to the room, and realises the purpose of room heating. Roof snow melting and anti-freezing can effectively prevent house damage and pedestrian injury caused by snow and ice. Electricity accompanies heat technology because it does not produce water vapour, do not need to reserve space and widely used.

　　2. Industrial field

　　In the industrial field, the electric accompanying heat technology is widely used in heating, warming and melting. Especially in the chemical industry, petrochemical and other industries in the fluid heating, electric accompanying heat technology has no calcium oxide, no cracking, no pollution, heating efficiency and other advantages. For example, in the heating of the oil pipeline, the electric accompanying heat technology can effectively prevent the oil in the pipeline from solidifying, and ensure the smooth transmission of oil.

　　3.Medicine field

　　In the medical field, the electricity accompanies the heat technology to be widely used in the laboratory environment control, the medicine heating and the storage and so on. In the laboratory environment control, electric accompanying heat technology in cell culture can be used for heat preservation, warming and continuous heating needs. In the drug heating and storage, the electricity accompanies the heat technology can be used in the drug crystal body heating to improve the permeability and need the constant temperature storage drug.

　　Third, the electric accompanies the heat technology's advantage

　　1. High efficiency and energy saving

　　The electricity accompanies the heat technology through the electric resistance heating effect directly the electric energy transforms into the heat energy, the heating efficiency is high, the energy utilisation rate is high. At the same time, the electricity accompanies the heat system to be able to carry on the precise control according to the actual demand, avoids the traditional heating method in the energy waste, achieves the highly effective energy-saving effect.

　　2. Safe and reliable

　　The electricity accompanies the heat system to have the good insulation performance and the protection measure, can prevent the electric shock accident effectively. At the same time, the electric accompanying heat system can carry on the precise control according to the actual demand, avoids the occurrence of overheating phenomenon, ensures the safety and reliability of the heating process.

　　3. Environmental protection and no pollution

　　The electricity accompanies the heat technology not to produce the harmful gas and the pollutant, has no pollution to the environment. At the same time, the electric accompanying heat system does not need to use the fuel, avoids the traditional heating method in the fuel consumption and the emission problem, achieves the environmental protection non-pollution effect.

　　4.Installation and maintenance is simple

　　The installation and maintenance of the electric accompanying heat system is relatively simple, does not need the complex equipment and operation. At the same time, the electric accompanies the heat system each component to be independent of each other, easy to replace and maintain, reduces the maintenance cost and the difficulty.

　　Fourth, the electric accompanying heat technology's future outlook

　　1. Intelligent control

　　With the development of internet of things and artificial intelligence technology, the electric accompanying heat system will realise more intelligent control. Through the sensor and intelligent controller, the electric accompanying heat system can adjust the heating power and temperature automatically according to the actual demand, and realise more accurate and efficient heating.

　　2. Application of new material

　　With the development of new material technology, the electric accompanying heat wire and heating tape will adopt more efficient and durable material to improve the heating efficiency and service life. At the same time, the application of new materials will also reduce the cost of electric heat tracing system, so that it is used in more fields.

　　3. Wider application field

　　With the continuous development and improvement of electric accompanying heat technology, it will be applied in more fields. For example, in the agricultural field, the electricity accompanies the heat technology can be used in the greenhouse greenhouse's heating and the heat preservation; In the traffic field, the electricity accompanies the heat technology can be used in the road and the bridge's antifreeze and the de-icing.

　　In short, electric accompanying heat technology as a kind of high efficiency, safety, environmental protection heating technology, has been widely used in many fields. In the future, with the continuous progress and development of technology, the electric accompanying heat technology will play an important role in more fields, and bring more convenience and benefit for people's production and life.
