It should be noted, however, that many of the details set forth in the description are merely provided to provide a thorough understanding of one or more aspects of the utility model, and that these aspects of the utility model may be practiced without these specific details.

Example 1:

as shown in fig. 1-4, a round dotting radiating pipe comprises a pipe body 1, wherein an uneven dotting structure is arranged inside and outside the pipe body 1, and the pipe body 1 is provided with two ends which are open and side sealing structures. Any point on the pipe body 1 is set as a pipe body with equal thickness, and can also be a structure with unequal thickness. I.e. the thickness of the tube wall is the same where the dots are and where they are not.

In the embodiment of the utility model, the rugged dotting structure comprises an outer concave point 2 and an inner convex point 3, wherein the inner convex point 3 is arranged in the pipe body 1, the outer concave point 2 is arranged outside the pipe body 1, and the outer concave point 2 and the inner convex point 3 are arranged in one-to-one correspondence. The inner convex points 3 are formed by the inward sinking of the outer concave points 2, and the thickness of the whole tube is not changed, so that the contact area in the tube can be increased by the inner convex points 3, and meanwhile, laminar flow is broken, and the heat conversion efficiency is higher. The rugged dotting structure is arranged as a long dotting structure, a round dotting structure, a square dotting structure or a cross dotting structure.

In the embodiment of the utility model, the pipe body 1 is rolled, rolled or rolled into a round structure by single-layer material and a welding seam 4 is arranged at the joint in a sealing way.

The composite material layer is a plating layer, a coating layer, an anodic oxidation layer or a PVD layer. The uneven dotting structures are set to eight-point dotting, equidirectional dotting, different-directional dotting or spiral dotting. The inner and outer layers of the heat dissipation pipe material are not necessarily the same technology or the same material, and include, but are not limited to, the inner layer is a coating, the outer layer is a coating, and the inner and outer layers are coatings.

Different dotting structures affect the flow velocity and turbulence of the fluid in the tube, and the effects of the different dotting structures are shown in Table 1. The data in table 1 are quantified experimentally for the same outside diameter, same flow rate, and same length.

In the embodiment of the utility model, the rugged dotting structure is a long dotting structure, 8 long dotting structure columns are arranged on the pipe body 1 at intervals, and the dotting directions of the long dotting structures on each long dotting structure column are the same. The long structure of long dotting structure dormitory is long to the page, can be rectangle or straight bar shape, realizes better heat dissipation.

The manufacturing process is as follows: the strip material is dotted for multiple times, then rolled and formed for multiple times, and then subjected to high-frequency welding or reflow welding, shaping for multiple times, and on-line cutting to obtain the radiating pipe.

By arranging different inclined directions at the intervals, the fluid is disturbed transversely, and the flow layer is broken better.

Example 3:

as shown in fig. 7-8, this embodiment differs from the real-time embodiment 1 in that 6 rows of elongated dotting structures are provided on the tube body 1, spaced apart.

Example 4:
