[0027] See attached Figure 1-5The present embodiment is described as an auxiliary installation device for a heat exchanger tube bundle with thin fins, comprising a cylinder 6, a plurality of heat exchanger tube bundles 1 and a plurality of thin fins 2, each group of the heat exchanger tube bundles 1 having thin fins 2 fixedly connected on both sides, and further comprising a docking track 3, a rear support assembly 4 and a front support assembly 5, wherein the rear support assembly 4 comprises a vertical plate 4-1, a bottom plate 4-2 and a plurality of support structures, wherein the vertical plate 4-1 is fixedly connected to the bottom plate 4-2, and the plurality of support structures are fixedly connected to the vertical plate 4-1, the rear support assembly 4 is rollingly connected to the docking track 3, and the front support assembly 5 comprises a support plate 5-1, a plurality of connecting plates 5-2 and a plurality of first pulleys 5-3, a plurality of tube bundle insertion holes 7 are uniformly provided on the support plate 5-1, the plurality of connecting plates 5-2 are uniformly fixed to one side of the support plate 5-1, each of the first pulleys 5-3 is rotatably connected to the side of the connecting plate 5-2, the first pulley 5-3 overlaps the inner wall of the cylinder 6 and rolls along the inner wall of the cylinder 6, each group of the heat exchanger tube bundles 1 is uniformly inserted between the corresponding front support assembly 5 and the rear support assembly 4 and is installed into the cylinder 6 through the front support assembly 5 and the rear support assembly 4.

[0028] The present invention provides stable support for the heat exchanger tube bundle 1 with thin fins 2 through the front support component 5 and the rear support component 4, and completes the transportation and installation of the heat exchanger tube bundle 1 with thin fins 2 in the cylinder 6 through the rolling connection between the rear support component 4 and the docking track 3 and the rolling of the first pulley 5-3 on the inner wall of the cylinder 6, ensuring that the thin fins 2 are not damaged, thereby ensuring the heat dissipation efficiency of the heat exchanger; through the setting of the docking track 3, the positioning of the heat exchanger tube bundle 1 with thin fins 2 and the inner wall of the cylinder 6 is facilitated, the docking process is simplified, the number of personnel required for the installation process is reduced, and the installation efficiency is greatly improved.

[0029] The support structure is a support tube 4-3 or a support socket. When the heat exchanger tube bundle 1 is a U-shaped heat exchanger tube bundle with thin fins, the support structure is a support tube 4-3. When the heat exchanger tube bundle 1 is a strip-shaped heat exchanger tube bundle with thin fins, the support structure is a support socket. Specifically, when the support structure is a support tube 4-3, a rib plate 8 is fixedly connected between each of the support tubes 4-3 and the vertical plate 4-1. The rib plate 8 improves the connection stability between the support tube 4-3 and the bottom plate 4-2.

[0030] The support plate 5-1 is connected to a fixing tube 9. The fixing tube 9 improves the strength of the support plate 5-1, reduces the deformation caused by the heat exchanger tube bundle 1 with thin fins 2 being inserted into the tube bundle insertion hole 7, ensures the accuracy of the connection between the heat exchanger tube bundle 1 with thin fins 2 and the cylinder 6, ensures that the thin fins 2 are not damaged, and thus ensures the heat dissipation efficiency of the heat exchanger.

[0031] A front bracket 10 is provided at one end of the cylinder 6 away from the rear support assembly 4. When the front support assembly 5 rolls out of the inner wall of the cylinder 6, the first pulley 5-3 is supported by the front bracket 10, so as to ensure the stability of movement of the heat exchanger tube bundle 1 with thin fins 2 during installation, and ensure that the thin fins 2 do not contact the inner wall of the cylinder 6 during installation, thereby ensuring that the thin fins 2 are not damaged.

[0032] The docking track 3 includes three tracks with the same interval, and each track is connected by a plurality of connecting blocks 11. The three tracks are connected by the connecting blocks 11 to ensure that when the rear support assembly 4 rolls on the docking track 3, the three tracks do not move relative to each other, thereby ensuring the stability of the installation process and ensuring that the thin fin 2 is not damaged.

[0033] The rear support assembly 4 is rollingly connected in the docking track 3 through a pulley assembly, and the pulley assembly includes a plurality of second pulleys 12 and a plurality of third pulleys 13. The plurality of second pulleys 12 are rollingly connected in the track in the middle of the docking track 3, and the plurality of third pulleys 13 are rollingly connected in the tracks on both sides of the docking track 3. Preferably, there are two second pulleys 12 and both are in the track in the middle of the docking track 3, and there are two third pulleys 13 and both are in the tracks on both sides of the docking track 3. The two second pulleys 12 can bear the weight of the heat exchanger tube bundle 1 with thin fins 2, and the two third pulleys 13 are auxiliary wheels to ensure that the moving process moves in a straight line.

[0034] The plurality of second pulleys 12 are rotatably connected to the lower surface of the bottom plate 4-2 through the connecting piece 14, and the plurality of third pulleys 13 are rotatably connected to one end of the extended connecting piece 15, and the other end of the extended connecting piece 15 is bolted to the side of the vertical plate 4-1. Through the arrangement of the connecting piece 14 and the extended connecting piece 15, it is ensured that the surfaces of the second pulley 12 and the third pulley 13 in contact with the docking track 3 are at the same horizontal plane, further improving the stability of the movement of the heat exchanger tube bundle 1 with the thin fins 2.

[0035] The length of the docking track 3 is not less than the length of the heat exchanger tube bundle 1. Specifically, the size of the docking track 3 is adjusted according to the specific length of the heat exchanger tube bundle 1 to adapt to the size change. By setting the length of the docking track 3 not less than the length of the heat exchanger tube bundle 1, it is ensured that when the heat exchanger tube bundle 1 with thin fins 2 is completely installed in the cylinder 6, the pulley assembly is still in the docking track 3, thereby improving the stability of the movement of the heat exchanger tube bundle 1 with thin fins 2.

[0036] When the multiple groups of heat exchanger tube bundles 1 are installed in the cylinder 6, the front support assembly 5 and the rear support assembly 4 at both ends of the heat exchanger tube bundle 1 are removed. The front support assembly 5 and the rear support assembly 4 are for auxiliary installation. When the heat exchanger tube bundle 1 with thin fins 2 is installed in the cylinder 6, the auxiliary installation function is completed, and then the front support assembly 5 and the rear support assembly 4 at both ends of the heat exchanger tube bundle 1 need to be removed.

[0037] An auxiliary installation method for a heat exchanger tube bundle with thin fins, wherein a docking track 3 is fixed at an installation site, multiple sets of heat exchanger tube bundles 1 with thin fins 2 are hoisted above the docking track 3, and are connected with a front support assembly 5 and a rear support assembly 4, and then the hoisting is released, the pulley assembly is rotated and connected to the corresponding docking track 3, the first pulley 5-3 is overlapped with the inner wall of a cylinder 6, the rear support assembly 4 is pushed to make the first pulley 5-3 move in a straight line direction, and the rear support assembly 4 is continuously pushed to the heat exchanger tube bundle When the heat exchanger tube bundle 1 is moved into the cylinder 6, one end of the heat exchanger tube bundle 1 close to the front support assembly 5 is hoisted to a height at which each thin fin 2 does not touch the inner wall of the cylinder 6, and the relative positions of the cylinder 6 and the plurality of heat exchanger tube bundles 1 are fixed by fixing parts, and then the front support assembly 5 is disassembled from the heat exchanger tube bundle 1. The disassembly method of the rear support assembly 4 from the heat exchanger tube bundle 1 is the same as that of the front support assembly 5. Finally, the docking rail 3 is disassembled to complete the auxiliary installation of the plurality of heat exchanger tubes with thin fins 2 and the cylinder 6.
