Quartz tube heater is a kind of heating equipment widely used in laboratory, industrial heating and semiconductor manufacturing. Its working principle is based on the electrothermal performance and heat conduction effect of quartz tube, so that electric energy can be efficiently converted into heat energy, so as to heat the surrounding objects or media.

Structure of quartz tube heater

The quartz tube heater is mainly composed of the following parts:

Power supply: Provides current to the quartz tube, which is the foundation for the operation of the heater.

Controller: used to adjust the current and temperature to ensure that the heater can operate stably and safely.

Quartz tube: A pipe made of high-purity quartz glass with good high temperature resistance, low thermal expansion coefficient and hot topic conductivity. Quartz tubes are divided into hollow quartz tubes and milky quartz tubes, which are slightly different in function.

Heating element: The hollow quartz tube usually passes through the heating resistance wire, and the milky white quartz tube is equipped with resistance alloy material as the heater.

Shell: Usually made of 304 stainless steel, it is used for installation, fixation and support.

Ceramic insulation: used to connect the quartz tube to the shell and provide insulation.

The working principle of quartz tube heater

The working principle of quartz tube heater is mainly based on the process of converting electrical energy into heat energy. When an electric current passes through the heating element (heating resistance wire or resistance alloy material), the electrical energy is converted into heat energy, which increases the temperature of the heating element. This heat is then conducted outward through the wall of the quartz tube, heating the surrounding object or medium.

Hollow quartz tube heater:

Current passes through a heating resistor wire, which generates heat.

Heat is conducted outward through the wall of the quartz tube, and part of the heat is emitted in the form of infrared radiation.

Part of the infrared rays penetrate the quartz and act directly on the heated material, and part is absorbed by the quartz tube, which is then converted into medium and long-wave rays for external radiation.

Opalescent quartz tube heater:

After electrification, 95% of the near-infrared and visible light emitted by the heating alloy wire is blocked and absorbed by the milky white quartz tube.

The temperature in the tube rises to produce molecular vibrations of pure silicon-oxygen bonds, which radiate far infrared rays.

Far-infrared rays with wavelengths greater than 2.5 micrometers are called far-infrared, and opalescent quartz tubes can convert most of the visible and near-infrared light into far-infrared light radiation.

The advantages of quartz tube heaters

Hot topic efficiency: The efficiency of converting electrical energy into heat energy is high, and the target object can be quickly heated.

Uniform heating: The heat conductivity of quartz tubes is good, ensuring uniform heating.

Quick response: The heating speed is fast and the set temperature can be reached quickly.

Long life: quartz tubes have high temperature resistance, high corrosion resistance, good chemical stability, and long service life.

Precautions for use

Safe operating procedures: When using quartz tube heater, follow safe operating procedures to avoid overheating and overloading.

Periodic inspection: Regularly check the heater's power supply, controller, quartz tube, and other components to ensure their normal operation.

Protective measures: Appropriate protective equipment should be worn during operation to avoid burns or other accidental injuries.

Quartz tube heaters have been widely used in many fields due to their high efficiency, uniform and fast heating characteristics, as well as long life and safety.
