Description

Technical Field

[0001] The utility model relates to the technical field of fin tube structures, in particular to a motion mechanism of a fin tube laser welding machine. Background Art

[0002] Spiral finned tube is a kind of high-efficiency heat transfer element with spiral fins. Its heat transfer area is several to dozens of times that of light tubes. It can enhance heat transfer, reduce flow resistance, and reduce metal consumption, thereby improving the economy and operational reliability of heat exchange equipment. Spiral finned tubes have been widely used in various boilers. Spiral finned tubes can be manufactured by a variety of methods. The finned tubes used in heat exchange equipment such as boilers and pressure vessels mainly have the following manufacturing methods: high-frequency resistance welded spiral finned tubes, brazed spiral finned tubes and integral spiral finned tubes. The manufacturing method, performance evaluation index, application of spiral finned tubes and the advantages of integral spiral finned tubes are introduced in detail.
