Spring heater

A spring heater, also known as a spring heater or coil heater, is a common electric heating conversion component used in industrial heating applications. It consists of a metal spring and a resistance wire made of a nickel-chromium wire (e.g. NiCr 80/20) high resistivity material to generate heat. When a current passes through a conductor with a resistance, electrical energy is converted to heat energy. This heater is shaped like a spring and is designed so that it can be tightly fitted to the surface of the part that needs to be heated, providing efficient heat transfer. The design of this heater allows it to flexibly adapt to the heating needs of a variety of different shapes and sizes.
