Working principle of tube heater

As a common heating device, the tube heater has a simple and efficient working principle.It converts electrical energy into heat energy to heat objects.The following is a detailed analysis of the working principle of the tube heater.

The tube heater is mainly composed of heating pipes, insulating materials, metal shells, etc.Among them, the heating pipe is a core component, and its internally is filled with resistive wires.When current passes through the resistor wire, due to the presence of the resistor, the electrical energy is converted into thermal energy, thereby heating the heating pipe.

Detailed explanation of the working principle of the tube heater

1. Electric energy is converted into thermal energy: The tube heater converts electrical energy into thermal energy through a resistive wire, which is its basic working principle.When current passes through the resistive wire, the resistive wire generates heat. 2. Heat conduction: The heating pipe transfers the heat generated to the heated object through heat conduction.Heating pipes are usually made of metal and have good thermal conductivity. 3. Temperature control: Tube heaters are usually equipped with a temperature controller that can adjust the heating temperature according to actual needs.The temperature controller automatically adjusts the current by detecting the temperature around the heating tube to ensure the stability of the heating temperature. 4. Safety protection: The tube heater has multiple safety protection measures, such as overheating protection, short circuit protection, etc., to ensure that the equipment can cut off the power supply in an abnormal situation and prevent safety accidents from occurring.

Application fields of tube heaters

Due to its high efficiency, stability and safety characteristics, tube heaters are widely used in the following fields:

• Food processing: such as baking, frying, and maturing.

• Chemical industry: such as reactor heating, pipeline heating, etc.

• Plastic processing: such as plastic melting, plasticizing, etc.

• Metal processing: such as metal heat treatment, metal smelting, etc.
