Spiral heat exchange pipeline for coaxial heat exchanger and manufacturing process of spiral heat exchange pipeline

The invention relates to the technical field of coaxial heat exchangers, in particular to a spiral heat exchange pipeline for a coaxial heat exchanger and a manufacturing process of the spiral heat exchange pipeline. The spiral heat exchange pipeline comprises a barrel, a heat exchange pipe body, a connecting rod, a stop block, a cleaning plate and a top block, wherein a sealing head is attached to the outer surface of the barrel; a water outlet is formed in the lower surface of the barrel; a fixing frame is fixedly welded to the outer surface of the water outlet; the heat exchange pipe body is fixedly connected to the interior of the barrel; and a supporting frame is fixedly welded to the interior of the water outlet. The spiral heat exchange pipeline for the coaxial heat exchanger and the manufacturing process of the spiral heat exchange pipeline have the beneficial effects that through the improvement on the basis of the prior art, the situation that the water outlet is blocked by dirt can be reduced throu
