[0025] Example:

[0026] This embodiment discloses a tube box structure that is easy to disassemble.

[0027] like Figure 1 As shown, the easily disassembled tube box structure includes plate 3, tube box 1, and heat exchange tubes 5. There are two plates 3, arranged parallel and spaced apart. The tube box 1 is a hollow structure, consisting of two tube boxes 1 positioned between the two plates 3. One tube box 1 has one end bolted to the first end of the two plates 3 on both sides near the plate 3, and the other tube box 1 has one end bolted to the second end of the two plates 3 on both sides near the plate 3. The heat exchange tubes 5 are arranged horizontally and parallel between the two plates 3, with both ends communicating with the interior of the tube box 1. The two plates 3 and the two tube boxes 1 together form a vertically arranged first channel.

[0028] Since the structures of the pipe box 1 at both ends are the same, the following description will take the pipe box 1 at the first end as an example.

[0029] like Figure 1 and Figure 2As shown, the casing 1 further includes a shell 11 and a cover 12. The shell 11 is a hollow structure with an opening 111 at the first end and a plug hole 116 at the second end, into which the heat exchange tube 5 is welded. The cover 12 is bolted to the first end of the shell 11 and covers the opening 111. First protrusions 112 extend from the first ends on both sides of the shell 11. After the first protrusions 112 extend, the width of the shell 11 is the same as the width of the cover 12, and the cover 12 is bolted to the first protrusions 112. Second protrusions 113 extend from the second ends on both sides of the shell 11, and extension portions 31 extend from the first ends on both sides of the plate 3. The second protrusions 113 are bolted to the extension portions 31.

[0030] like Figure 2 As shown, Figure 1 As shown, the pipe box structure further includes a pipe 115, which is located at the upper end of the pipe box body 1 and connects to the hollow structure of the pipe box body 1. Preferably, the upper end of the plate 3 is higher than the upper end of the pipe box body 1 and higher than the upper end of the pipe 115, while the lower end of the plate 3 is lower than the lower end of the pipe box body 1. This prevents the pipe 115 from being higher than the plate 3, which could cause damage during transportation and placement, and facilitates the transportation and placement of the pipe box structure. Figure 3 As shown, the tube box structure also includes a crossbeam 4. The crossbeam 4 is connected to the first end between the two plates 3 that are higher than the tube box 1 and to the first end between the two plates 3 that are lower than the tube box 1. The crossbeam 4 and the plates 3 enclose and extend the length of the first channel to ensure stable air intake in the first channel.

[0031] like Figure 3 As shown, further, a ring 114 is provided on the first end surface of the housing 11, the ring 114 is located outside the opening 111, and a second groove 121 is opened at the second end of the cover 12, the ring 114 is inserted into the second groove 121, thereby improving the sealing effect between the cover 12 and the housing.

[0032] like Figure 1 and Figure 2 As shown, the pipe box structure further includes a sealing ring 2, which is disposed between the cover 12 and the shell 11 and is sleeved on the outside of the ring 114, further improving the sealing effect between the cover 12 and the box.

[0033] In this embodiment, by bolting one end of one tube box 1 near the plate 3 to the first end of the two plates 3, and bolting one end of the other tube box 1 near the plate 3 to the second end of the two plates 3, the two plates 3 and the two tube boxes 1 form a vertically arranged first channel. Then, heat exchange tubes 5 are welded between the two tube boxes 1, so that the heat exchange tubes 5 are in the first channel, and the installation of the tube box structure can be completed. The structure is simple, easy to install and disassemble, and suitable for low-pressure media.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
