Abstract
Description
Technical Field
[0001] This utility model relates to the field of corrugated pipe technology, and more specifically, to a corrugated pipe. 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 of the spiral corrugated pipe is not perpendicular to the mold closing surface, the spiral corrugated pipe produced from the mold has crush marks or defects at the junction of the pipe pattern and the mold closing surface. This means that the spiral corrugated pipe needs to undergo secondary processing after the mold is made to repair the crush marks 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-shaped 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 the following advantages.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a corrugated pipe, comprising: a pipe body; N outwardly protruding C-shaped pipe patterns arranged sequentially and equidistantly on the side wall of the pipe body along the extension direction of the pipe body, wherein N is a positive integer greater than 1; the openings of the N C-shaped pipe patterns face the same direction to form an opening groove; N-1 S-shaped pipe patterns for connecting two adjacent C-shaped pipe patterns are arranged sequentially and equidistantly along the extension direction of the pipe body in the opening groove; one end of the S-shaped pipe pattern is connected to one end of the preceding C-shaped pipe pattern among two adjacent C-shaped pipe patterns, and the other end is connected to the other end of the following C-shaped pipe pattern among two adjacent C-shaped pipe patterns, so that the N C-shaped pipe patterns and the N-1 S-shaped pipe patterns are connected in series to form a pipe pattern passage.
[0005] Optionally, the length of the S-shaped tubular pattern is 0.5-1cm; the width of the S-shaped tubular pattern is 0.5-1cm; and its depth is 0.1-0.5cm.
[0006] Optionally, the width of the C-shaped tubular pattern is 0.5-1cm, and its depth is 0.1-0.3cm.
[0007] Optionally, the tube body is made of copper.
[0008] Optionally, both the inner and outer walls of the pipe are provided with anti-corrosion layers.
[0009] In summary, this utility model has the following beneficial effects: during the molding process, the C-shaped grooves on the corrugated pipe are always perpendicular to the mold opening surface, which can avoid damage or defects at the connection between the grooves of the corrugated pipe and the mold closing surface. After the corrugated pipe is processed and formed, it can be put into production and use, effectively improving production efficiency and reducing production costs. Attached Figure Description
