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 Construction

[0031] The idea, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of the present invention.

[0032] Such as Figure 4 , Figure 5 As shown, an elliptical flat spiral heat exchange tube of the present invention has a main body that is a metal tube body, especially, a metal welded tube in this embodiment. The tube body is surrounded to form a medium channel through which the heat exchange medium circulates, so as to realize the heat exchange of the medium inside and outside the tube.

[0033] In the present invention, the pipe body is composed of a special-shaped pipe section 10 located in the middle, and a first straight pipe section 11 and a second straight pipe section 12 respectively located at two ends of the special-shaped pipe section 10 .

[0034] The special-shaped pipe section 11 has an elliptical flat cross sect...

Abstract

The invention discloses an elliptical and flat spiral heat exchange tube, which at least comprises a tube body, wherein the tube body encircles a medium channel; the tube body is integrally formed by a special tube section in the middle as well as a first straight tube section and a second straight tube section at the two ends of the special tube section; the special tube section is provided with an elliptical and flat cross section; and the long axis and short axis of the ellipse form a rotation angle to the axis of the tube body. The invention also discloses a processing technology of the elliptical and flat spiral heat exchange tube. Due to the adopted special tube section, the elliptical and flat spiral heat exchange tube is simple in structure, easy to process, is utilized to improve the heat exchange efficiency of the tube body, has the beneficial effects of fewer dirts and easiness in cleaning, and can be widely applied to various heat exchange devices.

Description

technical field [0001] The invention relates to the technical field of metal tube processing, in particular to an elliptical flat spiral heat exchange tube used for heat exchange equipment such as heat exchangers. The present invention also relates to the processing technology of the aforementioned elliptical flat spiral 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 ...
