[0001] The utility model relates to the technical field of heat exchange equipment, in particular to an anti-corrosion fin tube which is easy to disassemble and assemble. Background Art

[0002] Fins are a device that uses the heat conduction effect to achieve heat transfer. By adding metal sheets with strong thermal conductivity to the surface of the heat exchange device where heat transfer is required, the heat exchange surface area of ​​the heat exchange device is increased.

[0003] With the use of fin heat exchangers, corrosion will occur inside the fin tubes, resulting in a decrease in the heat exchange effect of the fins. Traditional fin tubes are mostly connected by welding, and the fins cannot be maintained. Even after cutting, welding is still required, and disassembly and assembly are complicated and maintenance is inconvenient. Therefore, an anti-corrosion fin tube that is easy to disassemble and assemble is proposed. Utility Model Content

The second through tube is squeezed by the rotation of the threaded rod, and each fin is squeezed onto the first through tube to achieve the purpose of fin sealing. When the fin needs to be disassembled, it is only necessary to rotate the threaded rod and move the second through tube to one end close to the connecting plate, and the fin can be pulled out, which is convenient for disassembly and installation and improves the service life of the fin tube.

[0009] As a preferred technical solution of the utility model, both ends of the bellows are fixedly connected with connecting rings, and a plurality of springs are fixedly connected between the two connecting rings.

[0010] As a preferred technical solution of the utility model, when the No. 2 through pipe moves to the connecting plate, the distance between the No. 2 through pipe and the limiting plate is greater than the length of the fin.

[0011] The utility model has the following advantages: the device utilizes the rotation of the threaded rod to extrude the No. 2 through tube, and squeezes each fin onto the No. 1 through tube, thereby achieving the purpose of fin sealing; when the fin needs to be disassembled, it is only necessary to rotate the threaded rod and move the No. 2 through tube to one end close to the connecting plate, and the fin can be pulled out, thereby facilitating disassembly and installation and increasing the service life of the fin tube.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0016] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] The utility model will be further described below in conjunction with the accompanying drawings.

[0018] Please refer to Figure 1-Figure 2 The utility model discloses an anti-corrosion fin tube which is easy to disassemble and assemble, comprising a No. 1 through tube 1, both ends of the No. 1 through tube 1 are fixedly connected with side plates 2, one end of the two side plates 2 away from the No. 1 through tube 1 is fixedly connected with a connecting plate 3, a No. 2 through tube 4 which can reciprocate is arranged between the connecting plate 3 and the No. 1 through tube 1, and a plurality of fins 8 are equidistantly and detachably connected between the No. 2 through tube 4 and the No. 1 through tube 1.

[0019] A slide groove 5 is excavated on the inner side of the two side plates 2 near one end of the connecting plate 3, and a slider 6 is slidably connected inside the slide groove 5. The slider 6 is fixedly connected to the No. 2 through pipe 4 to facilitate the No. 2 through pipe 4 to slide between the two side plates 2. A threaded rod 7 is threadedly connected to the middle part of the connecting plate 3. The threaded rod 7 passes through the connecting plate 3 and is movably connected to the No. 2 through pipe 4. Both ends of the fin 8 are fixedly connected to a bellows 10. The end of the bellows 10 away from the fin 8 is fixedly connected to a trapezoidal sealing tube 11. The trapezoidal The sealing tube 11 is plugged into the No. 2 through tube 4, and both ends of the corrugated tube 10 are fixedly connected with connecting rings 12, and a number of springs 13 are fixedly connected between the two connecting rings 12. The trapezoidal sealing tubes 11 at both ends of the fins 8 are pushed by the springs 13 to press against the connecting port of the No. 1 through tube 1 and the No. 2 through tube 4. When the No. 2 through tube 4 moves to the connecting plate 3, the distance between the No. 2 through tube 4 and the limiting plate 9 is greater than the length of the fin 8. The longer distance makes it convenient to pull the fin 8 out of the limiting plate 9.

[0020] Specifically, when the utility model is used, when disassembling, the threaded rod 7 is rotated to make the No. 2 through pipe 4 lose its extrusion. After the No. 2 through pipe 4 is slid to connect only one end of the plate 3, the spacing between the No. 2 through pipe 4 and the limiting plate 9 is increased, and the fin 8 is pulled out from between them, which is convenient for disassembly, maintenance and replacement. When installing, the fin 8 is passed through the limiting plate 9, and the trapezoidal sealing tube 11 at one end is aligned with the connecting port of the No. 1 through pipe 1, and the threaded rod 7 is rotated in the opposite direction. As the threaded rod 7 rotates, the No. 2 through pipe 4 is squeezed and moved toward one end of the fin 8. As the threaded rod 7 continues to rotate, the squeezing force on the No. 2 through pipe 4 also increases, squeezing and contracting the spring 13 and the bellows 10, and the trapezoidal sealing tubes 11 at both ends of the fin 8 are pushed by the spring 13 to press against the connecting port of the No. 1 through pipe 1 and the No. 2 through pipe 4 to achieve sealing.

[0021] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
