Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3The utility model provides a technical solution: an internal helical threaded heat exchange tube with high efficiency in heat exchange, comprising an outer tube body 1, the outer wall of the outer tube body 1 is fixedly connected with a heat conductive protrusion 2, the inner wall of the outer tube body 1 is fixedly connected with an inner tube body 3, the inner wall of the inner tube body 3 is provided with a thread groove 4, and the inner wall of the thread groove 4 is provided with a through hole 5. By arranging the outer tube body 1, the heat conductive protrusion 2, the inner tube body 3, the thread groove 4 and the through hole 5, it is beneficial to increase the surface area inside the pipeline, thereby increasing the heat transfer area, improving the heat exchange efficiency, and helping the water flow to form a spiral flow, thereby generating turbulence, further improving the heat exchange efficiency, effectively solving the problem of slow heat exchange efficiency, meeting people's work needs, and worthy of popularization and use.

[0020] Furthermore, the outer tube body 1 is made of copper, which is beneficial to improving thermal conductivity.

[0021] Furthermore, the heat-conducting protrusions 2 are distributed in a spiral shape on the outer wall of the outer tube body 1, and the positions of the heat-conducting protrusions 2 and the through holes 5 correspond to each other, which is beneficial to improving the heat conduction efficiency.

[0022] Furthermore, the inner tube body 3 is made of copper, and the inner tube body 3 and the outer tube body 1 are an integrated structure, which further improves the thermal conductivity.

[0023] Furthermore, the thread grooves 4 are distributed in a spiral shape, and the depth of the thread grooves 4 is smaller than the wall thickness of the inner tube body 3, which is beneficial to increase the internal heat transfer area.

[0024] Furthermore, a plurality of through holes 5 are evenly distributed along the spiral shape of the thread groove 4, further increasing the heat transfer area.

[0025] When in use, firstly, by setting the heat-conducting protrusion 2, the external heat transfer area can be effectively increased, thereby improving the heat exchange efficiency, and by setting the threaded groove 4 and the through hole 5, it is beneficial to increase the internal heat transfer area, thereby further improving the heat exchange efficiency. At the same time, by setting the threaded groove 4, it is beneficial for the fluid to form a spiral flow, and by setting the through hole 5, the turbulence of the fluid flow is increased, so that the relative speed between the fluid and the pipe wall is increased, and then the fluid moves more violently, which can reduce the thickness of the laminar bottom layer, and the centrifugal force generated by the spiral flow can throw the droplets entrained in the steam back to the wall, thereby delaying the occurrence of wall drying, further enhancing the heat transfer between the fluid and the inner wall of the pipe, and then realizing the function of efficient heat exchange, solving the problem of slow heat exchange speed.
