Description

TECHNICAL FIELD

[0001] The utility model relates to electric radiation tube technical field especially relates to a kind of electric radiation tube with ventilation structure. BACKGROUND

[0002] As a key component in the field of modern industrial heating, electric radiation tube plays an important role in efficiently converting electrical energy into heat energy. This device is widely used in various industrial scenarios that require precise temperature control and rapid heating, such as heat treatment furnaces, melting furnaces, drying equipment, and chemical reaction kettles. The core advantage of electric radiation tube lies in its ability to quickly respond to temperature control instructions, achieving precise temperature regulation while maintaining high thermal efficiency and long service life. With the continuous progress of material science, electronic technology and automation control technology, the design and manufacturing level of electric radiation tube has been significantly improved, making it exhibit more outstanding performance in energy saving, environmental protection and intelligent control. Today, electric radiation tube has become an indispensable part of many industrial heating solutions, providing strong support for improving production efficiency, reducing energy consumption and ensuring product quality.

[0003] The working principle of electric radiation tube is based on the effect of electric heating conversion. Its core lies in the internal electric heating element. When electric current passes through the electric heating element, due to the existence of resistance, electrical energy is converted into heat energy, which follows Joule-Lenz law. The electric heating element is usually packaged in a high-temperature-resistant and corrosion-resistant protective sleeve, which not only ensures the safe operation of the electric heating element, but also enables the generated heat to be effectively radiated to the heated object. The ingenious design of electric radiation tube lies in its ability to transfer the heat generated by the electric heating element to the heated medium in two ways: radiation and convection, thereby achieving efficient and uniform heating effect. In addition, by adjusting the size of the current and the power-on time, the output power and heating speed of the electric radiation tube can be accurately controlled to meet the strict requirements of different processes on temperature and time. In some advanced applications, electric radiation tube is also equipped with an intelligent control system that can automatically adjust the working parameters according to the preset heating curve, further improving the accuracy and controllability of the heating process.

The air in the tube body can circulate, the thermal efficiency is high, and the service life is long.

[0005] As in the prior art of the above-mentioned patent, in order to increase the heat radiation effect of the electric radiation pipe, the internal heat energy is conducted out through the flowing air by opening the ventilation structure, however, the ventilation structure function is relatively single, and only fixed air vents are opened, and the direction of ventilation cannot be adjusted, and in the actual application process, the limitation of this design is obvious, because in some specific scenarios, directional heat radiation is required to achieve the best heating effect, for example, in the heat treatment process of large workpieces, it may be desirable to cover the specific area of the workpiece with heat radiation to promote uniform heating of the material in that area, while reducing the impact on other non-processing areas to maintain the overall performance of the material, for example, in the food processing industry, when drying food, the approximate direction of heat radiation may need to be adjusted according to the placement position and drying requirements of the food to ensure that the main heating area receives enough heat to improve drying efficiency and quality, in these specific cases, the electric radiation pipe with a fixed ventilation structure cannot meet the demand of directional heat radiation.
