This step of material selection is very important, and will affect whether the performance of the finished electromagnetic induction heater can be fully exerted. So, friends, do you know how to choose materials for self-made electromagnetic induction heaters? Self-made electromagnetic induction heaters . Electromagnetic induction heating originates from the phenomenon of electromagnetic induction discovered by Faraday, that is, the alternating magnetic field generates an induced current in the conductor, which causes the conductor to heat up. Since the discovery of the heating effect of electric current passing through a wire, there have been many inventors in the world engaged in research and manufacture of electric heaters. In 1890, Swedish technicians invented the first induction Induction melting furnace
, a slotted core furnace; in 1893, the prototype of an electric iron appeared in the United States; in 1909, the emergence of an electric stove realized the process of converting electrical energy into heat energy; In 1916, the Americans invented the closed-groove cored furnace, and the electromagnetic induction technology gradually entered the practical stage. 2. What is the principle of the electromagnetic induction heater? Kehua proposed that the heater body is designed according to the principle of induction heating and heat conduction. The heater body is immersed in water or liquid, and the induction coil is installed inside the heating body, so that the heating body forms In the inner and outer water chambers, the magnetic lines of force generated by the induction coils generate numerous eddy currents on the inner and outer walls of the water chamber, so that the inner and outer walls of the water chamber itself generate heat efficiently under the action of the eddy currents to heat the water or liquid in the water chamber. Self-made electromagnetic induction heaters 3. How to choose materials for self-made electromagnetic induction heaters 2. Electromagnetic heater IGBT temperature sensor: imported high-precision thermistor (70 degrees). Imported thermal grease is used to transfer the heat of the IGBT to ensure the safety of the IGBT module. 3. Electromagnetic heater fan: choose brushless AC fan, which has a larger air volume than brushed fan, with a life span of 20,000 hours and low noise (≤45dB. 4. Electromagnetic heater power supply: mainly use high-performance switching power supply. 5. Electromagnetic Heater IGBT: World Infineon module (high operating speed, high resistance to reverse high voltage, large working power, particularly good stability) 6. Electromagnetic heater heat sink: self-designed, fully meet the heat dissipation requirements of the circuit. 7. Electromagnetic heater High-voltage capacitors: high-voltage, high-frequency, high-precision, low-loss. How to choose materials for self-made electromagnetic induction heaters? I believe the above content can help you choose the most suitable materials, so that you can make electromagnetic induction heaters. The heater will perform very well.
