Steel-aluminum composite finned tubeA type of finned tube with two (or more) different treatment methods applied to its fins to enhance heat exchange. Its distinctive feature is the integration of the benefits of different strengthening methods on the same fin, thereby achieving superior overall performance. Double-metal rolling compositeFinned tubeComposed of fins with base pipes and wrapping packaging, the base pipes are typically made of carbon steel, stainless steel, or copper, with an aluminum tube wrapped around it. The aluminum tube is then extruded into fins using a rolling machine, while simultaneously forming a thin undercoat around the base pipe to securely encase it. The production methods for composite finned tubes mainly include welding and rolling techniques. It also details the enhancement of heat transfer, composite fins, and the main performance requirements for composite finned tubes. It integrates the respective advantages of composite tubes and finned tubes, making it a novel heat transfer tube that is widely researched internationally. Looking at both domestic and international information, Japan has conducted more development in the series of composite finned tubes. For example, Japanese patent literature has reported on the production of outer aluminum and inner stainless steel radial finned tubes using rolling techniques and outer aluminum and inner stainless steel axial finned tubes using welding methods. However, the products developed by Japan in this category are all inner smooth surface and outer finned composite tubes, which have not yet achieved the goal of fully utilizing the inner surface area of the tubes to improve their heat transfer performance. Moreover, these documents are all Japanese patents, so no further detailed reports have been made on the production processes of composite finned tubes.
