Silicon carbide rods heat up in what kind of way?

Silicon carbide rods use resistance to generate heat after powering up. The greater the current, the higher the temperature.

High temperature is emitted in the form of heat radiation

It produces far infrared rays. The ability of infrared rays is inversely proportional to the wavelength, which means that the greater the energy, the shorter the wavelength.

Therefore, the wavelength of the silicon carbide rod is very short and will not cause harm to the human body.

Of course if it’s too close, it will burn the skin.

Therefore, the equipment has a heat insulation layer, which is good for heat preservation and prevents thermal radiation burns.
