Electric heater is an internationally popular electric heating device. It is used to heat up, keep warm and heat the flowing liquid and gaseous medium. When the heating medium passes through the heating chamber of the electric heater under pressure, the huge heat generated by the electric heating element is evenly taken away by the principle of fluid thermodynamics, so that the temperature of the heated medium reaches the user's process requirements.
Electric heating is the process of converting electrical energy into thermal energy. Since the discovery that the power supply can produce thermal effects through the wire, many inventors in the world have been engaged in the research and manufacture of various electric heating appliances. The development and popularization of electric heating, like other industries, follows such a law: gradually promoted from advanced countries to countries around the world; gradually developed from cities to rural areas; from collective use to families and then to individuals; products developed from low-end to high-end. Most of the electric heating appliances in the embryonic stage of the 19th century were poor. The earliest electric heating appliances were used for life. In 1893, the prototype of the electric comforter first appeared and was used in the United States. Then in 1909, the use of electric stoves appeared. That was to place electric heaters in the stove, that is, the heating was transferred from firewood to electricity, that is, from electrical energy to thermal energy. However, the rapid development of the electric heating appliance industry came after the invention of nickel-chromium alloy used as electric heating elements. In 1910, the United States first successfully developed an electric iron made of nickel-chromium alloy heating wire, which fundamentally improved the structure of the electric iron, and the use of irons quickly became popular. By 1925, the product of installing electric heating elements in Japanese pots became the prototype of modern electric rice cookers. During this period, electric heating products such as laboratory electric furnaces, melt furnaces, and heaters also appeared in the industry. 1910 to 1925 was a major development stage in the history of electric heating appliances. In terms of households and industry, the emergence and popularization of various types of electric heating appliances have developed rapidly, especially in households. Therefore, the invention of nickel-chromium alloy laid the foundation for the development of the electric heating appliance industry.
With the popularization of many electric vehicles, more and more people are replacing traditional cars with electric vehicles.When the temperature is low in winter, traditional cars can use the heat energy generated by the engine to provide heat for the cab.Moreover, the electric motor of an electric car cannot generate enough heat energy to heat the cab.In addition, in winter, due to the low temperature, the battery chemical composition is not active and the battery power cannot be fully utilized. Electric car owners also need to heat the battery and increase its temperature to fully utilize the battery power.
Based on the above factors, electric vehicles will need a thermal management system more. And electric car heaters are one of the most important components of electric vehicles.
