A heater is an electrical appliance that uses electrical energy to achieve a heating effect. It is small in size, high in heating power, widely used, adopts intelligent control mode, has high temperature control accuracy, and can be networked with a computer. Wide application range, long life and high reliability. The core of the pipeline heater principle is energy conversion, and the most extensive is the conversion of electrical energy into heat. The heating speed is fast, the heat transfer efficiency is high, and it is not easy to scale. The oil can be heated quantitatively, and how much heating is needed. The oil does not have local high temperature and carbonization, which ensures the quality of the oil and the heat transfer efficiency of the heater.
For example, electric heaters use metal to generate eddy currents in an alternating magnetic field to make themselves heat and absorb, which converts electrical energy into light energy; such as solar water heaters, which absorb solar radiation heat energy and sunlight light energy (photoelectric effect) to convert both into heat energy Both; biological energy is a kind of energy stored in the form of chemical energy from solar energy as a carrier, which directly or indirectly originates from the photosynthesis of plants. In addition, there are energy conversion modes such as nuclear energy and wind energy, but they generally need to be converted into electrical energy.
There are many types of heater heating. Electromagnetic heating generates an alternating magnetic field through the electronic circuit board components. When an iron-containing container is placed on it, the surface of the container cuts the alternating magnetic lines of force to produce alternating magnetic fields at the bottom of the container. Electric current (that is, eddy current), eddy current causes the iron atoms at the bottom of the container to move randomly at high speed, and the atoms collide and rub against each other to generate heat energy. So as to play the effect of heating the article. Because the iron container heats itself, all the heat conversion rates are extremely high, as high as 95%. Induction cookers and induction cookers all adopt electromagnetic heating technology. The heat transfer form of infrared is radiation heat transfer, which transfers energy by electromagnetic waves.
