Heat exchange pipe for vacuum hot-water boiler

The utility model provides a heat exchange pipe for vacuum hot-water boiler, and the heat exchanger pipe not only can transfer heat effectively, but also can be conveniently manufactured, has low production cost, and can intensify heat transfer. The utility model adopts the technical scheme that the heat exchange pipe for vacuum hot-water boiler comprises a pipe body, wherein the shape of the pipe body is a wave node shape of neighboring convex and concave ring shapes. After the pipe body is bisected radially, the pipe wall forms two sine curves, the phase difference of the two sine curves is 180 degrees, the heat exchange pipe of the utility model is adopted, since the pipe body has the wave node of neighboring concave and convex ring shapes, water flow in the heat exchange pipe is in the high turbulence state, the heat exchange inside and outside the heat exchange pipe is more sufficient, and the heat exchange rate is improved by more than 40% according to test data.
