1. An application of electromagnetic induction in heating boilers. The medium-frequency current is passed into a boiler with an excitation coil as an induction heater and an iron core. The induction heater transmits electrical energy to the heater located in the induction heater by electromagnetic induction. Spiral heat exchanger with water.
2. Electromagnetic induction heating is characterized in that the flow rate of the heated water increases with the increase of power, and the heated water passes through the heat exchanger at a flow rate of I-10 meters per second.
3. A hot water boiler using electric energy, which includes a pot shell, a base, a heater using electric energy, and a heat exchanger. The heater and heat exchanger using electric energy are installed in the pot shell, and the pot shell is set on the base. There is a heat insulation and sound insulation layer or interlayer water jacket in the shell of the boiler, which is characterized in that: the heat exchanger is a spiral steel tube with a minimum of one radial layer formed by a boiler steel tube ring, and the boiler steel tube ring forming the spiral tube is in the axial direction of the spiral tube It is laminated with the radial direction; the heater is an induction heater that acts as an induction coil. The induction heater is a copper bar or copper tube with a rectangular cross section that is spirally wound. The induction heater is sheathed outside the heat exchanger , There is a gap or insulating layer between the induction heater and the heat exchanger, the gap or the insulating layer is 0.1-5cm, the copper strip ring or copper tube ring of the induction heater is separated from each other; the inside of the heat exchanger is also provided A magnetically enhanced energy storage iron core made of boiler steel pipe: a water pipe along the axis of the heat exchanger is provided in the middle of the inner side of the heat exchanger; a return water tank, a return water tank, a return water port and a sewage pipe are provided in the base The port is connected; the water pipe is connected with the return water tank , Jue heat exchange with the water pipe is directly or indirectly connected through the through port and is connected to the outlet pipe.
4. The electric energy hot water boiler is characterized in that the magnetically-enhanced energy storage iron core is a heat exchanger and a central water pipe, and the heat exchanger is a multi-layer spiral pipe radially stacked together.
5. The hot water boiler of electric energy is characterized in that the magnetically-enhanced energy storage iron core is a boiler steel pipe assembly in which the diameter of the inner water pipe is sequentially increased and sequentially nested in sequence with the central water pipe, and the The two ends are sealed by end plates, and there is an annular space between the sleeved boiler steel tubes. A radial partition is spaced in the radial direction in the annular space.
On the right side of the radial partition, there is a port at the end plate that communicates with the water cavity in the pot shell, the radial partition at the lower part of the annular space is the left side, and the outer boiler steel pipe has a ring leading to the second layer The spaced opening is at the upper part of the second layer of the annular space on the right side near the radial partition. The outer boiler steel pipe has a port leading to the third layer of the annular space. To the left near the partition, there is a ring-shaped spaced opening to the fourth floor, and so on. At the upper end plate of the outermost ring space, there is a water pipe communicating with the heat exchanger.
