Using the heating effect of resistance to convert electrical energy into thermal energy

A thermal oil furnace electric heater is a device that uses current to generate heat to heat the thermal oil. Its working principle is to use the resistance heating effect to convert electrical energy into thermal energy, and then transfer the thermal energy to the equipment that needs to be heated through the thermal oil.

The electric heater of the thermal oil furnace consists of heating elements, control system, and casing. The heating element is the core component of an electric heater, mainly composed of electric heating alloy wire, insulation material, and supporting rod components. Among them, electric heating alloy wires are made of nickel, chromium and other alloys, with high electrical resistivity, high temperature resistance, and good oxidation and corrosion resistance, making them good heating elements. The main function of insulation materials is to isolate heat sources and power sources to ensure the safety of the circuit. The supporting rod is used to fix electric heating alloy wires and insulation materials.

When the thermal oil furnace needs to be heated, the electric heater will be connected to the power supply through the control system, causing the electric heating alloy wire to heat up. Thermal energy is transferred to the thermal oil through insulation materials, and the thermal oil begins to be heated, gradually increasing in temperature. When heating, the control system will continuously detect the temperature of the thermal oil through sensors. Once the set temperature value is reached, the electric heater will automatically stop heating.

During the entire heating process, the shell of the thermal oil furnace electric heater also plays a very important role. It can not only protect heating elements and control systems, but also prevent harm to people and the environment. Therefore, when manufacturing thermal oil furnace electric heaters, the material of the outer shell must be sturdy and heat-resistant, usually made of steel plate or cast iron material.
