Problems solved by technology

During the heat exchange process, the heat exchange performed by the heat exchange medium close to the tube wall area of ​​the heat exchange tube is relatively sufficient, and the heat exchange efficiency is high; while the heat exchange medium located in the center area of ​​the heat exchange tube far away from the tube wall The heat exchange is not sufficient, so although the above-mentioned heat exchange tubes in the prior art have been improved to some extent, they each have their own shortcomings.

Embodiment 1

[0045] Such as Figure 4 , Figure 5 As shown, the arc-shaped heat exchange tube of the present invention has a main body of a metal tube body 1, especially, a metal welded tube in this embodiment. The pipe body 1 encloses and forms a medium channel 2 through which the heat exchange medium circulates, so as to realize the heat exchange of the medium inside and outside the pipe body 1 .

[0046] In this embodiment, the pipe body 1 as a whole is a special-shaped pipe section. Three arc-shaped grooves 31 are formed on the pipe wall of the special-shaped pipe section, and the three grooves 31 are parallel to each other and form a rotation angle with the axis of the pipe body 1 .

[0047] The three grooves 31 are correspondingly formed on the inner wall of the tube body 1 with three raised arc-shaped lines 32 .

[0048] In this embodiment, there are three grooves 31 arranged side by side. In other different embodiments, there may be one, two or more grooves.

[0049] In this emb...

Embodiment 2

[0054] Such as Image 6 As shown, another arc-shaped heat exchange tube of the present invention has basically the same structure as that of Embodiment 1, the difference is that the tube body 1 of the arc-shaped heat exchange tube also includes first straight pipe sections located at both ends 11 and the second straight pipe section 12.

[0055] In this embodiment, the lengths of the first straight pipe section 11 and the second straight pipe section 12 are unequal. Its beneficial effect is that when the arc-shaped heat exchange tube of the present invention is used for assembling heat exchange equipment, due to the limited space between the tube sheets, straight tube sections with unequal lengths at both ends are used, and the size can be borrowed from one end during assembly. , to make full use of the space between the tube sheets and improve the convenience of heat exchange equipment installation.

[0056] Of course, under normal circumstances, the first straight pipe sec...

Embodiment 3

[0060] The present invention also provides a processing technology for the above-mentioned arc-shaped heat exchange tube, which includes the following steps: Step 1, obtaining a metal round tube, specifically, a metal welded tube in this embodiment. Step 2, put the metal round tube into the roller machine, keep the metal round tube still, and process and form one or more arc-shaped extending grooves on the tube wall of the metal round tube by turning the mold while moving the mold, so as to Correspondingly arc-shaped lines are formed on the inner wall of the tube.

[0061] As an improvement or optimization of the above-mentioned processing technology, the following processing steps can also be added:

[0062] Flatten the middle section of the metal round tube obtained in step 2, so that the middle part of the arc-shaped heat exchange tube is oval, and then bend the oval metal round tube into a U-shape or an S-shape. A first straight pipe section and a second straight pipe sec...

Abstract

The invention discloses a spiral arc-shaped heat exchange pipe, which at least comprises a pipe body, wherein the pipe body encircles to form a medium channel and is a special pipe section; a groove which extends in an arc shape is formed on the pipe wall of the special pipe section, and forms a rotary included angle with an axis of the pipe body; and the groove is provided with convex arc-shaped grains on the inner wall of the pipe body correspondingly. The invention also discloses several machining processes for the spiral arc-shaped heat exchange pipe. In the spiral arc-shaped heat exchange pipe, due to the adoption of the special pipe section with the structural design, arc-shaped ripples are formed on the inner wall of the heat exchange medium channel; when a heat exchange medium flows in the medium channel, the heat exchange medium is subjected to turbulent influence of the arc-shaped ripples while rotating, and a turbulence effect is obvious, so a heat exchange effect of the heat exchange medium inside the pipe and outside the pipe is full, and the heat exchange efficiency of the pipe body is improved; and the spiral arc-shaped heat exchange pipe has the advantages that a few scales are formed, the spiral arc-shaped heat exchange pipe is easy to clean and the like, and can be widely applied to various heat exchange devices in fields of industry, household appliances, automobiles and the like.

Description

technical field [0001] The invention relates to the technical field of metal tube processing, in particular to an arc-shaped heat exchange tube used for heat exchange equipment such as heat exchangers. The present invention also relates to the processing technology of the aforementioned arc-shaped heat exchange tube. Background technique [0002] The heat exchange tube is a key component of the heat exchange equipment, and the heat exchange efficiency of the heat exchange tube directly affects the working efficiency of the heat exchange equipment. Therefore, those skilled in the art have been devoting to adopt various ways to improve the heat exchange efficiency of the heat exchange tubes. [0003] Such as figure 1 As shown, CN201780028U discloses a "spiral heat exchange tube". The heat exchange tube 1 is a spiral heat exchange tube made by bending a copper tube. The direction of the two connectors 2 of the heat exchange tube 1 is It is consistent with the axis direction ...
