Electric heating installation is a device or appliance that converts electrical energy into heat energy after the heating device is energized.
Electric heating installation due to the heating principle, components, adjustment and control methods are different, the heat energy increases to form different temperature rise rates, the common classification is as follows.
This kind of electric heating installation is made according to the thermal effect of the current. The heating body is a metal conductor or non-metal conductor with a certain resistance value. Its products are electric stove, electric stove, electric iron, electric heater and so on.
Far infrared electric heating equipment is a device that uses far infrared radiation elements on the basis of current thermal effect to radiate far infrared heating objects. Far-infrared heating is an advanced energy-saving technology, which has been widely used in food processing, baking, heating and so on. Its products are far infrared electric heater, far infrared electric oven, far infrared physiotherapy device and so on.
It is well known that conductors generate an induced current in an alternating magnetic field, and heat is generated when internal resistance is overcome in the conductor. This is how induction heating works. Electromagnetic cooker is an electric cooker made according to this principle.
Microwave electric heating equipment is a new heating technology, is the use of microwave devices composed of ultra-high frequency oscillator, and then through the waveguide, antenna radiation of electromagnetic waves - microwave to cook food equipment. This type of electric heater is generally called microwave oven. Cooking food with microwave stoves is 4 to 12 times faster than ordinary electric or fuel stoves.
Arc heat produces high temperature, to achieve melting, welding, burn mark equipment, its products are electric engraving machine, electric ironing pen, electric furnace, electric arc furnace, electroslag furnace, submerged arc furnace, welding machine, etc.
Electric heating installation, such as vapor deposition, ion glow equipment, laser machine, etc., that uses ionized high-energy particle beams to produce continuous high temperature airflow or rays.
