[0048] Reference Figure 1-5A detachable floating coil heat exchanger includes a tank body 1, support legs 2, and a heat exchange mechanism. The tank body 1 has an inlet pipe 3 and an outlet pipe 4 horizontally positioned on its side wall. A drain pipe 5 is located at the lower end of the tank body 1, and an exhaust valve 6 and a safety valve 7 are located at the upper end. The tank body 1 is a cylindrical shell 8, comprising a shell 8, an upper end cap 9, a lower end cap 10, an upper tube sheet 11, and a lower tube sheet 12. The top and bottom of the shell 8 are fixedly connected to the upper end cap 9 and the lower end cap 10 by bolts. Support legs 2 are welded to the bottom of the tank body 1 for stable support of the overall structure. The shell 8 is connected to the upper end cap 9 and the lower end cap 10 via the upper tube sheet 11 and the lower tube sheet 12. Both the upper tube sheet 11 and the lower tube sheet 12 have threaded holes and are connected to the shell 8 and the end caps by bolts for easy disassembly and maintenance. The heat exchange structure includes a first grid plate 13, a second grid plate 14, an inlet pipe 15, an outlet pipe 16, a first branch pipe 17, a second branch pipe 18, a coil 19, a distribution pipe 20, and connecting components. The first grid plate 13 and the second grid plate 14 are horizontally fixed inside the tank 1. The second grid plate 14 is located below the first grid plate 13 and has an opening, forming an installation space between them. Both the first grid plate 13 and the second grid plate 14 are mesh plates to achieve filtration and diversion of impurities. One end of the inlet pipe 15 is inserted into the tank 1 for inputting the heat medium; one end of the outlet pipe 16 is inserted into the tank 1 for outputting the heat medium. The inlet pipe 15 and the outlet pipe 16 are respectively connected to the first branch pipe 17 and the second branch pipe 18. The first branch pipe 17 is connected to the inlet pipe 15, and the second branch pipe 18 is connected to the outlet pipe 16. Both are connected to both ends of the coil 19 through the distribution pipe 20.

[0049] The first branch pipe 17 is connected to the input pipe 15 by a thread, and the second branch pipe 18 is connected to the output pipe 16 by a thread. The first branch pipe 17 and the second branch pipe 18 have the same structure, both adopting a segmented pipe body. The segmented pipe bodies are connected by threads, which facilitates the installation and disassembly of the input pipe 15 and the output pipe 16, and also facilitates the disassembly and replacement of the first branch pipe 17 and the second branch pipe 18.

[0050] The connection assembly includes a connecting pipe 21, a fixing block 22, and a sealing component; the connecting pipe 21 is disposed on the diversion pipe 20 and is connected to the diversion pipe 20.

[0051] A fixing block 22 is fixedly installed inside the connecting pipe 21 at one end away from the diverter pipe 20. A tapered guide hole 23 is provided on the fixing block 22. The cross-section of the guide hole 23 gradually decreases from the outside to the inside. A sealing element is provided on the inner wall of the connecting pipe 21 to seal the guide hole 23. One end of the coil 19 is connected to a sealing plug 30. One end of the sealing plug 30 is inserted into the guide hole 23 and seals against it. Both the sealing plug 30 and the guide hole 23 are tapered structures.

[0052] The sealing component includes a support rod 24, a housing 25, a connecting rod 26, a sealing ball 27, a limiting ring 28, and a spring 29. The support rod 24 is fixedly installed inside the connecting pipe 21, the housing 25 is installed on the support rod 24, the connecting rod 26 is slidably installed through one end of the housing 25, the sealing ball 27 is fixedly installed on one end of the connecting rod 26 to seal the guide hole 23, the limiting ring 28 is fixedly installed on the end of the connecting rod 26 away from the sealing ball 27 and is located inside the housing 25 and slidably connected to the inner wall of the housing 25, and one end of the spring 29 is connected to the limiting ring 28, and the other end is connected to the inner wall of the housing 25. The diameter of the sealing ball 27 is the same as the diameter of the rear end face of the guide hole 23. When coil 19 is not installed, spring 29 pushes the sealing ball 27 to press tightly against the rear end face of guide hole 23, achieving a seal. When installing coil 19, sealing plug 30 is inserted into guide hole 23 and pushes open sealing ball 27, allowing heat medium to flow through coil 19. Thus, through the cooperation of conical sealing plug 30 and guide hole 23, combined with the sealing structure of spring 29, tool-less installation and removal of coil 19 can be achieved. At the same time, the precise cooperation between sealing ball 27 and guide hole 23 ensures no leakage of medium.

[0053] A manhole 31 is provided on the tank body 1, and a sealing plate 32 is installed on the manhole 31. One end of the sealing plate 32 is engaged with the coil 19, and a handle 33 is provided on the sealing plate 32. The handle 33 is located outside the tank body 1. By pulling out the sealing plate 32 through the handle 33, the coil can be removed or replaced through the manhole 31.

[0054] The workflow is as follows:

[0055] The heat medium enters the first branch pipe 17 from the inlet pipe 15, and is distributed to each coil 19 via the branch pipe 20. After exchanging heat with the cold fluid in the tank 1, it flows into the second branch pipe 18 and is discharged through the outlet pipe 16. When the coil 19 needs to be replaced, the inlet and outlet pipes 16 are closed, the sealing plate 32 is removed, and the coil 19 is pulled out from the guide hole 23. The sealing component automatically seals the guide hole 23 to prevent leakage. When installing a new coil 19, the sealing plug 30 is directly inserted into the guide hole 23. The sealing ball 27 is pushed open, and the spring 29 is compressed, achieving sealing and connection.
