The article will consider an example of how to make the simplest heater from improvised means. Of course, this is just a sample, reflecting the principle of the device, the process of its assembly and so on. But on the basis of the described scheme, it is possible to assemble a more powerful version, with which it will be possible to heat without problems garage or house.
The device works directly from the 220 Volt network, no power supplies are required.
Materials and tools for creating a heater:
- two pieces of glass (you can cut any necessary);
- some aluminum foil;
- ordinary candle;
- sealant, glue and so on;
- a cotton swab or any other similar object;
- a piece of wire with a plug (two cores);
- it is desirable to have a multimeter;
- soldering iron.
Heater manufacturing process:
Step one. Create an analog film
First, the glass must be thoroughly washed and cleaned, there should be no traces of dirt and grease on it. Next, an ordinary candle is taken, set on fire, and with it you need to thoroughly smoke one half of the glass. In total, the author moved the glass back and forth about 4 times so that it smoked well. You also need to make at least three pauses before "smoking". That is, to smoke the glass the first time, then the second and again the third. The stronger the glass is smoked, the more the heater will heat.
Step Two Assembly assembly
Now you need to take a cotton swab and carefully collect the excess pieces of soot on the glass. In total, a distance of about 0.5 cm needs to be cleaned along the edge. Next, you need to take the foil and cut out two electrodes from it, in width they should be such as the width of the remaining soot on the glass.
Now you can assemble the device. The electrodes are superimposed on the soot, and glue is applied at the edges of the glass. Now you need to carefully press the halves together and let the glue dry. That's all, the heater is ready.
Step Three Heater Tests
As a result of testing a homemade heater, it was possible to determine that it has a resistance of 40 kOhm.The thicker the soot layer, the lower the resistance and the higher the temperature, and vice versa. As a result, the estimated power of the sample was about 1.2 W.
When the heater was turned on in the network, it began to heat up very slowly, while at the 40th minute its temperature reached 37 ° C. The temperature did not rise above, apparently this is a turning point at which there was a balance between heating and heat transfer.
As a result, the device works fine and you can collect a sample of already large sizes. By the way, the picture of soot can be varied; it is not at all necessary that it be a strip. Thus, you can make any picture that will warm no worse. In any case, this is just a model and there are still many ways to improve the system.
