[0032] The following is combined with Figure 1-Figure 5 This application is described in further detail.

[0033] An embodiment of the present application discloses a fin-type heat exchanger that is easy to splice.

[0034] A fin-type heat exchanger that is easy to splice includes a base tube 1, fins 2, a positioning assembly 3 and a locking assembly 4. A plurality of fins 2 are provided, and the plurality of fins 2 are evenly distributed along the length direction of the base tube 1.

[0035] Each fin 2 comprises a plurality of fin units 21, which are evenly distributed circumferentially along the axis of the base tube 1. Each fin 2, composed of these fin units 21, forms an annular arrangement, and each fin 2 is sleeved onto the base tube 1. A positioning assembly 3 is located between two adjacent fin units 21 and is used to position them so that they lie on the same plane and form an annular overall shape. A locking assembly 4 is used to secure each fin 2 to the base tube 1.

[0036] When installing fin 2 on base tube 1, several fin units 21 are distributed circumferentially along the axis of base tube 1. Positioning assembly 3 then positions these fin units 21, giving the fin 2 an annular shape and fitting it onto base tube 1. Locking assembly 4 then secures each fin 2 to base tube 1, completing the installation of each fin 2. To remove fin 2, locking assembly 4 disconnects fin 2 from base tube 1, followed by positioning assembly 3 to disconnect adjacent fin units 21, facilitating removal of fin 2.

[0037] In the embodiment of the present application, two fin units 21 are provided, and the two fin units 21 are arranged opposite to each other.

[0038] Each fin unit 21 includes a fin body 22 and a mounting block 23 .

[0039] The fin body 22 and the mounting block 23 are integrally formed. In the embodiment of the present application, two mounting blocks 23 are provided, and the two mounting blocks 23 are located at both ends of the fin body 22 .

[0040] When installing the fins 2, the two fin bodies 22 clamp the base tube 1, and the mounting blocks 23 on the two adjacent fin bodies 22 contact each other to complete the positioning of the fin bodies 22. The larger contact area between the two adjacent mounting blocks 23 further improves the contact stability of the two adjacent fin bodies 22.

[0041] There are several positioning assemblies 3 , and the several positioning assemblies 3 correspond to the several fin units 21 . In the embodiment of the present application, there are two positioning assemblies 3 .

[0042] Each positioning assembly 3 includes a positioning plate 31 and a positioning block 32. The positioning block 32 is fixedly installed in the middle of the positioning plate 31.

[0043] Each mounting block 23 is provided with a through-slot 231. To position the fin bodies 22, the positioning plate 31 is inserted into the through-slots 231 of two adjacent mounting blocks 23. The positioning plate 31 is then rotated to position the positioning blocks 32 within the through-slots 231. This allows the positioning blocks 32 to contact the inner walls of the through-slots 231, thereby aligning the fin bodies 22 on the same plane.

[0044] To facilitate the movement of the positioning plate 31 within the inner wall of the limiting groove 231, a plurality of protrusions 221 are fixedly mounted on the side of the fin body 22 near the positioning plate 31. These protrusions 221 limit the positioning plate 31, thereby improving the stability of the positioning plate 31. Furthermore, the protrusions 221 on the fin body 22 facilitate heat transfer to the positioning plate 31, further increasing the overall heat exchange area and improving the heat exchange effect.

[0045] In the embodiment of the present application, the protrusion 221 is arranged in a hemispherical shape, and the protrusion 221 and the positioning plate 31 are in point contact. The hinged contact area between the protrusion 221 and the positioning plate 31 facilitates the polishing of the contact area, reduces the gap between the positioning plate 31 and the protrusion 221, and further improves the convenience of moving the positioning plate 31.

[0046] The locking components 4 are provided in plurality, and the plurality of locking components 4 corresponds to the plurality of mounting blocks 23 in the embodiment of the present application.

[0047] The locking assembly 4 includes a locking rod 41 and a locking bolt 42 .

[0048] A first locking groove 232 is defined on the inner wall of the limiting groove 231 , and a second positioning groove 321 is defined on the side wall of the positioning block 32 . Both the first locking groove 232 and the second positioning groove 321 are arc grooves.

[0049] The mounting block 23 is provided with a first locking hole 233 and a second locking hole 234 that extend through the positioning block 32. Both the first locking hole 233 and the second locking hole 234 are circular holes, with the first locking hole 233 located away from the base pipe 1, while the second locking hole 234 is located closer to the base pipe 1. Both the first locking hole 233 and the second locking hole 234 are pluggably engaged with the locking rod 41, and the locking bolt 42 is threadedly connected to the first locking hole 233.

[0050] When installing the fin 2 on the base tube 1, the locking rod 41 is inserted from the first locking hole 233 into the second locking hole 234. The locking rod 41 then positions the positioning plate 31 by interfacing with the inner walls of the first locking groove 232 and the inner walls of the second locking hole 234. The locking bolt 42 is then tightened to secure the locking rod 41 against the base tube 1, thereby enhancing the stability of the fin 2 installation.

[0051] The implementation principle of the fin-type heat exchanger that is easy to splice in the embodiment of the present application is as follows: when installing the fin 2 on the base tube 1, the two base tubes 1 are clamped to hold the base tube 1, and the two positioning blocks 32 are in contact. Then, the positioning plate 31 is inserted into the limiting groove 231, and the positioning plate 31 is in contact with the protrusion 221. Then, the positioning plate 31 is slid so that the positioning block 32 is placed inside the limiting groove 231. Then, the locking rod 41 is inserted from the second locking hole 234 through the first locking groove 232 and the second locking hole 234 to position the positioning block 32. Then, the locking bolt 42 is tightened so that the locking bolt 42 pushes the locking rod 41 against the base tube 1. When removing the fin 2, the fin 2 can be removed in the order of the installation direction.

[0052] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
