According to the following description, the advantages and features of the present utility model will be clearer. It should be noted that the drawings are in a very simplified form and use non-precise scales. The orientation or positional relationships indicated by terms such as "center", "lateral", "length", "width", "height", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "side", etc. are based on the orientation or positional relationships shown in the drawings, rather than indicating or implying that a heat exchange tube or component must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be construed as a limitation of the present utility model. It is only used to conveniently and clearly assist in explaining the objectives of the embodiments of the present utility model. In order to make the objectives, features and advantages of the present utility model more obvious and understandable, please refer to the accompanying drawings.

[0023] It should be noted that the structures, ratios, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present utility model. Therefore, they do not have technical substantive significance. Any modification of the structure, change in the proportional relationship or adjustment of the size, without affecting the efficacy that the present utility model can produce and the objectives that can be achieved, should still fall within the scope covered by the technical content disclosed by the present utility model.

[0024] The following describes the specific structure of a heat exchange tube:

[0025] Please refer to Figures 1 to 3 , the heat exchange tube of this embodiment includes a pipe fitting body 1, and an efficiency improvement component 2 for improving the heat exchange efficiency is arranged inside the pipe fitting body 1. The efficiency improvement component 2 includes a first element 201 and a second element 202 arranged in sequence.

[0026] Furthermore, the first element 201 and the second element 202 are evenly arranged inside the pipe fitting body 1, such that the first element 201 and the second element 202 are equidistantly arranged, effectively ensuring that the flow distances of the fluid when successively touching the first element 201 and the second element 202 are equal, and improving the stability of the fluid.

[0027] Furthermore, the centers of the positions of the first element 201 and the second element 202 at the pipe fitting body 1 both coincide with the center of the pipe fitting body 1, thereby ensuring the uniform distribution of the first element 201 and the second element 202 relative to the end faces of the pipe fitting body 1 respectively.

[0028] Further, the first element 201 is an annular structure and its annular surface is connected to the inner wall of the pipe body 1. The surface of the second element 202 is provided with evenly distributed protrusions 2021, and one end of the protrusion 2021 is connected to the inner wall of the pipe body 1. Preferably, the first element 201 and the second element 202 are connected to the inner wall of the pipe body 1 by welding to improve the firmness under fluid impact without displacement.

[0029] Furthermore, the first element 201 is provided with a first hole 2011, the center of the first hole 2011 coincides with the center of the body of the first element 201. The first element 201 also includes a flow guide surface 2012 symmetrically arranged along a first direction, and the flow guide surface 2012 is formed from the edge of the annular end surface of the first element 201 to the first hole 2011. In this embodiment, the first direction is the direction in which the center of the end surface of the tube body 1 is formed around a curve to form a heat exchange tube.

[0030] Furthermore, the drainage surface 2012 is composed of a first curved surface 20121 and a second curved surface 20122 connected together, and a third curved surface 2022 is symmetrically arranged along the first direction on the surface of the second element 202. By arranging the first curved surface 20121, the second curved surface 20122 and the third curved surface 2022, a smooth transition can be achieved when the fluid flows through the first element 201 and the second element 202, and a certain acceleration effect can be achieved on the fluid, thereby promoting the flow of the fluid.

[0031] Furthermore, each of the protrusions 2021 can overlap or stagger with each other along the first direction. In this way, the second element 202 can be rotated around the end face of the pipe body 1 at its position by an appropriate angle according to the needs of different customers, thereby changing the direction of fluid flow in the heat exchange tube, thereby improving adaptability to different working conditions.

[0032] The technical features of the above-described embodiments can be combined arbitrarily. In order to make the description concise, all possible combinations of the technical features in the above-described embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. The above-described embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the utility model, several deformations and improvements can be made, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
