The heating method of the car heating seat cushion:
1. Electricity and heat are two different forms of energy. According to the law of energy conversion, the heating plate knows that they can be converted into each other. All kinds of electrical appliances are converted by an electric heating element.

According to the working principle of electric heating elements, there are five kinds of resistance heating, induction heating, microwave heating, arc heating and infrared heating. Arc heating is the voltage between two electrodes, the discharge between electrodes and electrodes, or between electrodes and elements, which promotes the air ionization arc generated by the high temperature heating element.

2. Induction heating
According to electromagnetic theory, if a conductor is placed in an alternating magnetic field, an induced current (eddy current) will be generated inside the conductor, and the eddy current will overcome the resistance inside the inner conductor to generate heat. Electric heating devices that use eddy currents to generate heat are called induction electric heating devices.

The principle of induction heating is essentially a resistance heating, but its working current is not directly obtained from the power supply, but obtained through induction. Hence, it is called induction heating. Induction heating can be divided into two types: iron core induction heating, ironless. The core induction heating is to use the principle of the transformer to heat the auxiliary winding of the transformer, such as an induction soldering iron.

Coreless induction heating is the heating of the object under alternating magnetic fields, in the eddy current of induction heating, using an electric blanket covering the heating object, such as the electromagnetic range of household appliances. If the working frequency is 5060hz, as the working frequency induction cooker; if the high-frequency current higher than 20kHz is a high-frequency induction cooker, then the induction cooker is mainly a high-frequency induction cooker.

3. microwave heating
This is a method of heating a medium to a high frequency alternating electric field, using microwaves (LMM lm) to illuminate the heat of the molecules inside the medium. Electric heating devices made from this heating principle are called microwave electric heating devices.

4. Infrared heating
When the electric heating element-resistance heats the wire, its electrical energy is converted into heat energy to heat some infrared radiation, the radiation of infrared rays to objects, using the principle of electrical appliances is called infrared electric heating appliances.

The principle of external electric heating equipment is the radiant heating mode, and the convection and conduction methods have more obvious advantages, such as improving thermal efficiency, which can greatly save energy, fast heating, strong penetrating ability, saving time, etc. Common infrared electric heaters have infrared Heaters, electric stoves, etc.
