Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and more specifically to a corrosion-resistant, small-diameter finned tube heat exchanger. Background Technology

[0002] Tubular heat exchangers are widely used heat transfer devices in chemical, petroleum, energy, and pharmaceutical industries. Their core principle is to separate two fluids at different temperatures through solid walls (heat exchange tubes), achieving efficient heat transfer. Early heat exchangers had simple structures, mostly single-tube or shell-and-tube designs. With industrial development, they have evolved into modern shell-and-tube heat exchangers with complex multi-tube and shell-side designs. Traditional designs face problems such as low heat transfer efficiency, easy fouling, and high flow resistance, prompting continuous optimization of materials, structures, and processes. For example, corrugated tubes and finned tubes are used to enhance heat transfer elements and improve efficiency; corrosion-resistant materials (such as titanium alloys and stainless steel) are used to extend service life; and modular designs are introduced to facilitate maintenance. Furthermore, the application of computational fluid dynamics (CFD) and intelligent control technologies has further optimized flow distribution and thermodynamic performance. Currently, tubular heat exchangers are developing towards high efficiency, energy saving, compactness, and intelligence to meet emerging demands such as green manufacturing and waste heat recovery, becoming one of the key devices for industrial energy conservation and emission reduction.

[0003] Insufficient technology: During the use of existing equipment, the tilt angle of the heat exchanger needs to be adjusted according to actual usage requirements. However, adjusting the angle requires users to spend a lot of time, which is inconvenient for users. In addition, the contact area of ​​the heat exchange tube is small during use, which makes it difficult to ensure heat exchange efficiency. Utility Model Content
