Description

Technical Field

[0001] The utility model relates to the technical field of fin tube laser welders, in particular to a material guiding mechanism of a fin tube laser welder. Background Art

[0002] Spiral finned tube is a high-efficiency heat transfer element with spiral fins. Its heat transfer area is several to dozens of times that of a light tube. 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 in a variety of ways. 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. This paper introduces in detail the manufacturing method, performance evaluation indicators, applications and advantages of integral spiral finned tubes of spiral finned tubes. Spiral finned tubes have two welding methods, one is to weld both ends of the fin to the steel pipe, and the other is to weld the contact surfaces of the fin and the steel pipe. Compared with the first method, the second method has better thermal conductivity and fits the steel pipe more closely.

[0003] When welding spiral finned tubes, the diameter of the steel pipe used varies depending on the application scenario and location. The material guide mechanism of existing laser welders is not convenient for adjusting the contact distance between the fins and the steel pipe according to the diameter of the steel pipe. Therefore, it is urgent to design a material guide mechanism for finned tube laser welders to solve this problem. Utility Model Content
