AI Technical Summary
The support structure of the existing U-shaped tube cooler has problems such as complex installation, high accuracy requirements, large welding workload, easy to damage the pipe, and insufficient heat transfer effect and stiffness.
The supporting clip made of plastic is formed by forming an integral structure at the tail of the U-shaped tube, and fixed by using the concave and convex notches between the supporting clips and flat steel to form a circular hole to support the U-shaped tube, increasing stiffness and damping, simplifying the installation process.
The natural vibration frequency of the U-shaped tube is improved, vibration is reduced, heat transfer is enhanced, installation complexity and weight are reduced, and axial flow resistance on the shell side is reduced.

Abstract
Description
Technical Field
[0001] The utility model relates to a cooler, in particular to a tail support structure of a U-shaped tube of a cooler. Background Art
[0002] For traditional U-shaped tube coolers, there are roughly four types of tail support structures for their U-shaped tubes, and more or less there are defects:
[0003] Type A support structure: From inside to outside, between the bending parts of adjacent rows of U-shaped tubes, round steel with a diameter of 6 mm is inserted side by side, and all the round steel is fixed with 2 flat steel clamping plates outside the tube bundle to achieve the purpose of fixing the heat exchange tubes. The disadvantage of this structure is that for each additional layer of U-shaped tubes, the straight section length of the tubes needs to be increased by 6 mm.
[0004] Type B support structure: A support plate is arranged at the tail of the U-shaped tube. After the support plate is drilled according to the tube layout drawing, it is cut into strips along the center line of each layer of tubes. From inside to outside, 1 strip of plate is placed for each row of tubes installed, and the adjacent 2 strips of plate are welded into a whole, and so on until the installation and welding of the outer layer of tubes and strips are completed. This structure requires high cutting accuracy of the support plate and a large amount of welding work for each strip of plate after the tubes are inserted.
[0005] Type C support structure: This structure uses 1 U-shaped round steel concentric with the U-shaped tube and 1 Π-shaped round steel perpendicular to it, which are welded at the vertex, and then anti-vibration spacing rods are inserted into each layer of tubes. Both ends of the spacing rods are respectively welded to the Π-shaped round steel. This structure requires precise bending of the spacing rods and a large amount of welding work for each spacing rod after the tubes are inserted.
[0006] Type D support structure: This structure first saws short tubes as collars. During assembly, the collars are first put on the bent U-shaped tubes, and are installed row by row from inside to outside, and are welded tightly and aligned with the collars of the front row. This structure requires the collars to be put on before assembly, and small current is required for the welding between the collars to avoid damaging the tubes due to improper welding. Content of the Utility Model
[0007] The utility model provides a tail support structure of a U-shaped tube of a cooler.
[0008] The technical solution of the utility model:
[0009] A tail support structure of a U-shaped tube of a cooler, the support structure includes at least one support clip, and a plurality of support clips are installed inside the shell side cylinder body of the U-shaped tube cooler at the tail of the U-shaped tube, and the support clips are connected together to form a whole. Circular holes are formed between adjacent support clips, and the circular holes match the outer diameter of the U-shaped tube, and the tail of the U-shaped tube passes through and is supported in the circular holes;
[0010] Holes are arranged on the support clips.
[0011] The supporting clip is a plastic part.
[0012] There are concave-convex notches between adjacent multiple supporting clips, and the concave-convex notches are inlaid.
[0013] The whole formed by connecting each supporting clip together is wrapped around by flat steel and fixed through the flat steel.
[0014] The outer periphery of the whole formed by connecting each supporting clip together is a complete surface.
[0015] The hole is formed by hollowing out and is consistent with the contour of the supporting clip; the supporting clip is a thin-walled structure.
[0016] The advantages of the utility model are as follows: reasonable design, simple structure, effectively supporting the pipe, meanwhile playing a damping role, enabling the tail of the U-shaped pipe to form a whole, increasing the stiffness of the tube bundle, raising the natural vibration frequency, and reducing the possibility of generating vibration; having the advantage of a large contact surface with the pipe, changing the flow channel between the pipes after being inserted into the tube bundle, enhancing the heat transfer effect, having a small resistance to the axial flow on the shell side, being convenient for installation, and being light in weight.
