need for warmth is felt by us since ancient times.Another cave man hiding in the skin from the cold, without assuming that the heat can be obtained in various ways.
To date, the most affordable source of heat is a common household outlet.But to convert electricity into heat requires a special device that can be bought in a store or make your own hands that much more interesting.Let us in this article will look at some principles of transformation of electricity into heat, and the feasibility of creating such devices.
Make a heater with your hands is easy, but first you need to decide for what purpose you want to use it.
If you are going to heat well ventilated room, such as a garage or workshop, you'd better just stay at the heater, based on the principle of converting electricity into heat by means of the working fluid that is heated to high temperatures.
Heat in this case is transferred to the surrounding area by a fan.
power of such a device is sufficient to calculate Ohm's law and construct a device with regard to electrical and fire safety.
Try as a heating element to use ceramics which is heated by means of two metal plates.Make a heater with your hands not be easy and will not take a lot of time, most importantly, to think of ways the body of the device, and hardware components, as well as calculate the heater power.If the garage or a private house, there are three phases, it is possible to construct a more powerful instrument combining heating elements in a "star".In this case, the power consumption will increase, but you will be able to heat a large area.
If your goal is to design efficient heater with your hands, then we must follow a different principle: increasing the area of the heating element, and a decrease in the heating temperature.Take two sheets of plastic and put on one of them snake layer of graphite epoxy glue.You should get a graphite conductor with an area as large as possible, do not leave a lot of empty space on the plastic, try to fill the surface evenly.At the end of the conductor paste the copper plates and display the power cord.Overlay a second sheet of plastic and glue them.
you made an economical and durable heater with your hands.Before switching on make sure to check the resistance heater with an ohmmeter.Homemade heater must have a high ohmic resistance.If all is well, safely connect to the network.In normal operation, the temperature of the plastic surface does not exceed sixty degrees.For security, when you first start, you can use a voltage regulator, gradually increasing to a nominal voltage and monitor the condition of the heater.
Using this principle, you can assemble a small car heaters, pre-thought-out design and installation location of the device.It will serve as an additional source of heat in the cabin during the cold winter.
