Technical Field
[0001] The utility model belongs to the technical field of heat exchange tubes, in particular to a high-efficiency fin heat exchange tube. Background Art
[0002] In the fermentation industry and biopharmaceutical industry, compressed air is often needed. Since the compressed air from the air compressor outlet is in a high temperature and high humidity state, it cannot be used directly. Therefore, air pretreatment equipment is needed to cool and dehumidify the compressed air and use it after it becomes dry air. Among them, the cooling part of the air pretreatment equipment often uses finned heat exchange tubes to cool the air. The finned heat exchange tube includes a base tube and fins on the outer surface of the base tube. Because the surface area of the heat exchange tube after finning is 9 to 12 times that of the base tube, it is particularly suitable for cooling air. In particular, the extruded finned heat exchange tube is made by extruding the fins and the base tube, with high overall strength and high heat exchange efficiency.
[0003] According to a disclosed high-efficiency extruded fin heat exchange tube (publication number: CN211317042U), it includes a base tube and fins. The inner diameter of the base tube is 18mm to 25mm. The inner wall surface of the base tube is processed with 4 to 5 spiral grooves arranged in the same direction along the length direction. The cross-section of the spiral groove is V-shaped. The 4 to 5 spiral grooves are evenly arranged along the circumference of the base tube. However, in the above device, it is difficult to achieve the effect of cleaning the inner wall of the tube body through the mutual cooperation of components such as the base tube and the fins, resulting in dust accumulation and easy corrosion of the tube body, which needs to be improved.
