Heating electric boiler refers to all electric boiler products used in the heating industry. It can be said that the range is very wide, the heating methods are different, and the product names are also different. They are generally divided into resistance electric boilers, PTC electric boilers, electromagnetic boilers and other products.
The resistance type electric boiler distributes the high-temperature resistance wires evenly in the high-temperature-resistant stainless steel seamless tube, and densely fills the crystalline magnesium oxide powder with good thermal conductivity and insulation performance in the gap portion. This structure heats quickly, has high thermal efficiency and The heating is uniform. When a current passes through the high-temperature resistance wire, the generated thermal energy is diffused to the surface of the metal pipe through the crystalline magnesium oxide powder, and then transferred to the heated water to achieve the purpose of heat dissipation and heating.
PTC electric boilers abandon the traditional backward process of directly heating water with electric heating. PTC semiconductor ceramics are used scientifically as heating elements. The principle of semiconductor holes is used to achieve electron oxygen vacancies, which promotes the occurrence of magnetic collisions of electrons under strong magnetic fields. Electric energy is converted into thermal energy in the form of a molecular bond with a working medium in the form of a plane. The PTC heating sheet is heated on the outer wall of the water tank, thereby realizing the separation of water and electricity and greatly improving the safety factor.
The electromagnetic boiler uses the principle of electromagnetic induction to convert electrical energy into magnetic thermal energy. In the controller, a 50 / 60Hz AC voltage is converted into a DC voltage by a rectifier circuit, and then the DC voltage is converted into a high frequency of 20-25KHz by a control circuit. Voltage and fast-changing current will generate high-speed magnetic field when passing through the coil. When the magnetic field lines inside the magnetic field pass through a metal container of a specific material, numerous small eddy currents will be generated, which will cause the metal container to quickly heat itself, and then transport the water in the container to The heat sink circulates to achieve the purpose of heat dissipation and heating. Compared with other technologies using direct heating by a metal heating body, electromagnetic eddy current heating has unparalleled advantages.
