How to make an induction furnace and heating boiler from an inverter
The use of induction coils instead of traditional heating elements in heating equipment has significantly increased the efficiency of the units with less electricity consumption. Induction heaters went on sale relatively recently, besides at relatively high prices. Therefore, craftsmen have not left without attention to this topic and figured out how to make an induction heater from a welding inverter.
Every day induction heaters are gaining popularity among consumers due to the following advantages:
-high efficiency;
-the unit runs almost silently;
-induction boilers and heaters are considered to be quite safe in comparison with gas equipment;
-the heater is fully automatic;
-the equipment does not require constant maintenance;
-due to the tightness of the device, leakage is excluded;
due to vibrations of the electromagnetic field, the formation of scale becomes impossible.
Also the advantages of this type of heater include the simplicity of its design and the availability of materials for the assembly of the apparatus with their own handsThe inductor type heater contains the following elements.
Current generator. Thanks to this module, the alternating current of the household power grid is converted to high frequency.
Inductor. It is made of copper wire, twisted in the form of a coil, to form a magnetic field.
A heating element. It is a metal tube placed inside the inductor.
All of these elements, interacting with each other, work on the following principle. The high-frequency current developed by the generator is fed to an inductor coil made of copper conductor. The high frequency current is converted by the inductor into an electromagnetic field. Further, the metal pipe inside the inductor is heated due to the effect of vortex flows on it in the coil. Heat carrier (water) passing through the heater takes heat energy and transfers it to the heating system. Also, the coolant acts as a cooler of the heating element, which prolongs the "life" of the heating boiler.
The following structural elements will be required to assemble the boiler.
Inverter. The device is chosen such power, what is needed for the heating boiler.
Thick wall tube (plastic), you can brand PN. Its length should be 40-50 cm. Coolant (water) will pass through it. The inner diameter of the pipe must be at least 5 cm. In this case, the outer diameter will be 7.5 cm. If the inner diameter is smaller, then the boiler capacity will be lower.
Steel wire. You can also take a bar of metal with a diameter of 6-7 mm. From a wire or a bar small pieces (4-5 mm) are cut. These segments will act as a heat exchanger (core) of the inductor. Instead of steel pieces, you can use a metal tube of smaller diameter or a steel screw.
PCB sticks or rodsOn which the induction coil will be wound. The use of PCB will save the pipe from the heated coil, because this material is resistant to high temperatures.
Insulated cable 1.5 mm cross section 2 and a length of 10-10.5 meters. Cable insulation must be fibre, enamel, fiberglass or asbestos.
Induction heating boiler is assembled according to the following algorithm. Fill the body of the heat exchanger with metal products, as discussed above. At the end of the tube that serves as the body, solder adapters that are suitable in diameter to the tubes of the heating circuit.
If necessary, you can solder corners to adapters. Should also solder American coupling. Thanks to them, the heater will be easy to dismantle, for repair or maintenance inspection.
The next step is to stick the heat exchanger to the housing. textolite stripson which the coil will be wound. You should also make a pair of racks 12-15 mm high from the same PCB. They will be located contacts for connecting the heater to the converted inverter.
