Manufacturing method of filament spiral heat exchange assembly for tubular heat exchanger

The invention discloses a manufacturing method of a filament spiral heat exchange assembly for a tubular heat exchanger and relates to the field of heat exchange devices. The tubular heat exchanger mainly solves the problem that an existing tubular heat exchanger is poor in heat exchange efficiency. A metal wire A is wound into a spiral spring-shaped edge wire, a U-shaped core wire is made of a metal wire B, one edge wire of the U-shaped core wire is inserted into the spiral spring-shaped edge wire, and the other edge wire of the U-shaped core wire is located on the outer side of the spiral spring-shaped edge wire. Under the condition that the spiral spring-shaped side wire is clamped by the U-shaped core wire, the closed end of the U-shaped core wire is connected to a hook at the end of a rotating shaft of rotating equipment, the free end of the U-shaped core wire is fixed to a clamp, walking wheels at the bottom of the clamp are arranged on a rail, and a spring is connected between the clamp and the end of
