[0002] In order to facilitate heat exchange for a vertical tank body, a heat exchange outer tube is usually arranged on the outer edge of the vertical tank body. However, due to the size and shape of the vertical tank body, multiple heat exchange outer tubes must be welded end to end to form a heat exchange structure that can be applied to the outer edge of the vertical tank body. During long-term use, due to the welding effect at the weld, the weld is subject to more cracking risks than the tube body, causing the heat exchange medium to leak from the weld, thereby affecting the heat exchange effect. Therefore, the weld needs to be reinforced to ensure the heat exchange effect and service life of the heat exchange structure. Utility Model Content

Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0018] Figure 1 The schematic diagram shows the arrangement of the heat exchange outer tube with a reinforcement structure. Figure 1 As shown, it includes a heat exchange outer tube 2 attached and fixed on the outer edge of a vertical tank body 1. The heat exchange outer tube 2 is obtained by welding a plurality of tube bodies end to end. A reinforcement structure 3 is fixedly arranged at the welding position of the aforementioned plurality of tube bodies. The reinforcement structure 3 includes a sleeve 4 and a sealing cloth 5. The sealing cloth 5 and the sleeve 4 are fixedly arranged at the welding position in sequence. The two ends of the sleeve 4 are respectively fixed on adjacent tube bodies, and an expansion joint 6 is fixedly arranged in the middle of the sleeve 4.

[0019] It is worth noting that the aforementioned heat exchange outer tube 2 is a half tube, and the sleeve 4 is also a half tube structure. The sleeve 4 is fixed to the outside of the heat exchange outer tube 2 based on the outer edge surface of the vertical tank body 1.

[0020] By adjusting the aforementioned heat exchange outer tube 2 to a half tube, the plate can be rolled into a half tube structure and then directly fixed to the outer edge surface of the vertical tank body 1 to serve as the heat exchange outer tube 2, which can effectively save materials and costs; and the provided sealing cloth 5 is used to wrap part of the weld to avoid leakage of the refrigerant in the heat exchange outer tube 2 due to cracking of the weld. In addition, the welding part is further sealed and locked by the sleeve, so that the heat exchange outer tube 2 part has the ability to resist bending, pulling and sealing.

The length of the aforementioned sealing cloth 5 is greater than the length of the sleeve, and a latch is arranged on the side of the partition block 7 facing the tube body. The latch is used to further lock the sealing cloth 5 on the weld surface and complete the fixing of the sealing cloth 5, which can effectively prevent the sealing cloth 5 from sliding along the axial direction of the heat exchange outer tube 2 at the weld, thereby affecting its sealing effect on the weld.

[0022] In order to facilitate the fixing and positioning of the casing, the casing is set as a split structure, including a left casing and a right casing separated along the center line of the casing, and a plurality of embedded grooves 8 and embedded blocks 9 are set on the opposite side of the left casing and the right casing, and the embedded blocks 9 are embedded in the embedded grooves 8 to complete the positioning and fixing of the left casing and the right casing. The expansion joint 6 is set on the center line of the casing, and the expansion joint 6 can also be separated into left and right parts, and also includes a locking block 10, which is sleeved on the expansion joint 6 and is used to lock the separated expansion joint 6.

[0023] During the actual assembly, the sealing cloth 5 is first laid on the weld of the heat exchange outer tube 2, and then the aforementioned left-side sleeve or right-side sleeve is placed on the sealing cloth 5, and the edge of the sleeve is fixed to the outer edge of the vertical tank body 1 by welding, and then the other half of the sleeve is positioned and locked by the embedding block 9 and the embedding groove 8, and the expansion joint 6 is locked by the locking block 10, and then the aforementioned other half of the sleeve is also welded to the outer edge of the vertical tank body 1.
