2. Different conductive media; Electromagnetic induction heating, real separation of water and electricity, circuit and waterway insulation. Resistance heating transfers heat to the water bag through the heat conducting medium, resulting in large heat loss.
3, the composition materials are the same; Carbon fiber heater is a pure blackbody material, so it has the characteristics of fast temperature rise, small thermal lag, uniform heating, long heat radiation transmission distance and fast heat transfer speed. The heating element of the heating wire is made of resistive material.
4. Different heating principles; Carbon fiber heating pipe is a kind of heating pipe, and the heating cable is a low-temperature heating wire.
Extended data
Working principle of electric heating:
High-frequency high-frequency current flows to the heating coil (usually made of copper tube), which is wound in a ring or other shape. Therefore, a strong magnetic beam with instantaneous polarity change is generated in the coil. When a heated object such as metal is put into the coil, the magnetic beam will penetrate the whole heated object, and a corresponding large eddy current in the opposite direction to the heating current will be generated inside the heated object.
Because there is resistance in the heated object, it will produce a lot of Joule heat, which will make the temperature of the object rise rapidly. Achieve the purpose of heating all metal materials.
