Heating element in production and in everyday life
The history of the electric heater starts from 1859year, when the American Simpson patented a way of converting electrical energy into heat. In the first half of the last century, General Electric began mass production of a device in which the heating element was sealed in a tube with insulating material. From that moment, the scope of application of electric heating devices has been constantly expanding. They gradually appeared in everyday life, and found wide application in production. The design of the device has also undergone significant changes. Until now, only the principle of transforming electrical energy into heat remained intact.
Now we can not imagine our life without manyhousehold appliances. The heating element is used in household electric heaters, electric irons, dishwashers, etc. It is also used in the manufacture of warm floors, special heat cables are used here. Widely used was the use of thermal cables and in production, as heating pipelines or electric machines. A small heating element can be found in the control cabinets, its purpose is to maintain a constant temperature regime in the winter. This is necessary so that when the ambient temperature changes, condensation does not form, which can negativelyaffect the work of the whole managingtechnological process of equipment. Modern electric machines are also equipped with special anti-condensate windings, the direct purpose of which is to keep the temperature of the motor windings above the ambient temperature, in order to avoid condensation. These windings - and there is a heating element that extends the life of the electric machine.
Recently, more and more widespreadreceive heaters, as a working element in which a ceramic heating element is used. Its design features significantly improve the operational parametersclassical electric heaters.The working body of such heaters is ceramics, which is heated by means of metal plates. The advantages of this design are obvious, unlike the coil electric heaters, the heating of the ceramic is much faster. Due to the fact that the ceramic is practically not destroyed by heating, the durability of the device is significantly increased. It is also advantageous to use ceramic heaters in terms of fire safety.
Another example of the use of heatingelements in everyday life is a heating element for a washing machine. You probably paid attention to the fact that the connection of a washing machine requires the supply of cold water only. The temperature regime during washing is provided by the automatic system, and as special heating elements, special electric teens are used.
