What is a lithium battery heater?
Lithium ion battery heaters are a more widely used heating treatment method in the industrial economy and civil construction equipment management of China today. They use electromagnetic heating technology, which can be abbreviated as IH (Induction Heating) technology. They are continuously developed and combined on the basis of Faraday's law of induction, and are an important application form of Faraday's law of induction. The oil drum heating belt adopts the soft and bendable characteristics of a silicone heating plate. Metal buckles are riveted on both sides of the heating plate with reserved holes, and spring buckles are used to fasten to the barrel, pipeline, and tank body. Easy and fast installation. It can make the silicone rubber heating plate use the tension of the spring to tightly adhere to the heated part, heating quickly and with high thermal efficiency. Lithium battery heaters have basic functions, such as heating, constant temperature, and temperature control. The battery energy storage heater is very thin, lightweight and flexible With this heater, you can transfer heat anywhere you need, improve heat transfer, accelerate heating, and reduce power requirements during processing.

Its essence is to use electromagnetic induction to generate eddy currents inside the cylinder to heat the silicone rubber heating strip of the workpiece. It converts electrical energy into electromagnetic energy, and then converts it into electrical energy. Electrical energy is converted into thermal energy inside the metal to achieve the purpose of heating the metal. Therefore, it eliminates the harm and interference of open flames in the heating process, and is a relatively environmentally friendly and advocated heating solution.

Lithium battery heaters are devices that convert electrical energy into heat using the principle of electromagnetic induction. The electromagnetic controller converts 220V/380V, 50/60Hz AC current into DC through a rectification circuit, and then converts DC into voltage of different frequencies through a control circuit, generating a variable magnetic field through the coil. When the magnetic field of the transverse magnetic line passes through the magnetic metal (iron, cobalt, nickel) material and generates countless small eddy currents in the metal body, the metal material itself is heated at high speed, thereby achieving the purpose of heating the metal material.

The heating method of silicone rubber heating belt is to transfer heat to the cylinder through contact conduction. Only heat close to the inner surface of the cylinder can be transferred to the cylinder. In this way, most of the heat is lost to the air from the outside, causing heat conduction losses and an increase in ambient temperature. In addition, resistance wire heating has the disadvantage of low power density and cannot be used in certain high-temperature heating situations. Electromagnetic heating technology uses the principle of electromagnetic induction to heat the metal barrel itself, and can wrap a certain thickness of insulation material outside the barrel according to specific situations, greatly reducing heat loss and improving thermal efficiency. Therefore, the energy-saving effect is very significant, up to 30% to 75%. Due to the fact that the electromagnetic heating coil itself does not generate heat and is made of insulating materials and high-temperature cables, there is no problem of high-temperature oxidation of the resistance wire of the original silicone rubber heating belt, which shortens its service life. It has the advantages of long service life, fast heating speed, and no need for maintenance, which shortens maintenance time and reduces costs. It has been widely adopted by plastic product enterprises, greatly reducing their production costs.
