Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe technology, and more specifically, to a corrugated pipe with a loop-shaped pipe pattern. Background Technology

[0002] Traditional heat exchanger tubes typically have coaxial and parallel cylindrical or elliptical cylindrical surfaces for their inner and outer walls. To improve heat transfer efficiency, existing heat exchanger tubes have been modified into spiral corrugated tubes with spiral grooves formed on the inner circumference of the tube body, creating spiral protrusions on the outer circumference. However, during the manufacturing process of these spiral corrugated tubes, issues arise... Figure 3 As shown, because the central axis of the spiral pattern 2 of the spiral corrugated pipe 1 is not perpendicular to the mold closing surface of the mold 3, the spiral corrugated pipe after mold opening has pressure marks 4 or defects at the connection position between the pipe pattern and the mold closing surface. This means that the spiral corrugated pipe 1 needs to undergo secondary processing after mold opening to repair the pressure marks 4 or remove the defects before it can be put into production and use, resulting in low production efficiency and high processing costs. To address this, we propose a corrugated pipe with a loop-type pipe pattern. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a corrugated pipe with loop-shaped tubular patterns to solve the technical problems existing in the background art.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a corrugated pipe with a loop-shaped tubular pattern, comprising: a first connecting part, a second connecting part, and a pipe body; the first connecting part is fixedly disposed at one end of the pipe body; the second connecting part is fixedly disposed at the other end of the pipe body; N outwardly protruding C-shaped tubular patterns are arranged equidistantly along the length direction of the side wall of the pipe body, wherein N is a positive number greater than 1; all N C-shaped tubular patterns are perpendicular to the central axis of the pipe body; the openings of the N C-shaped tubular patterns face the same direction to form an opening groove; N-1 semi-annular tubular patterns for connecting two adjacent C-shaped tubular patterns are arranged along the length direction of the pipe body in the opening groove; the N-1 semi-annular tubular patterns connect the N C-shaped tubular patterns in series to form a loop-shaped tubular pattern.

[0005] Optionally, the width of the C-shaped tubular pattern is 0.5-1cm, and its depth is 0.1-0.3cm.

[0006] Optionally, the depth of the semi-annular tube is 0.1-0.3 cm.

[0007] Optionally, the first connecting part, the tube body, and the second connecting part are integrally formed.

[0008] Optionally, the first connecting part, the second connecting part, and the tube body are all made of copper.

[0009] Optionally, both the inner and outer walls of the pipe are provided with anti-corrosion layers.

[0010] In this invention, the C-shaped grooves on the corrugated pipe are always perpendicular to the mold opening surface during the molding process. This avoids damage or defects at the connection between the grooves and the mold closing surface. Once the corrugated pipe is formed, it can be put into production and use, effectively improving production efficiency and reducing production costs. Attached Figure Description
