[0002] The heat exchanger coil is the core component of a heat exchanger. The coil consists of spiral or serpentine pipes, allowing different fluids to exchange heat on the coil walls. However, existing heat exchanger coils are prone to deformation after prolonged use due to fluid scouring or external pipe vibration. This deformation can lead to micro-cracks and eventually leaks. Furthermore, the transportation of heat exchanger coils after manufacturing can also cause pipe deformation and even micro-cracks, posing safety hazards. Summary of the Invention

[0003] The technical problem solved by this utility model is to provide a heat exchanger coil structure that reduces the risk of deformation of the coil during long-term use or transportation.

[0004] Technical solution: To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A heat exchanger coil structure includes a base plate, a first coil connected to the base plate, and a first support connected to the base plate. The first coil includes a first spiral tube segment and a first inlet pipe and a first outlet pipe connected to the first spiral tube segment. The first inlet pipe and the first outlet pipe both penetrate the base plate. A first gap is formed between adjacent tubes of the first spiral tube segment. The first support includes a top plate connected to the base plate, a column connected to the top plate, and a plurality of first fixing blocks connected to the column. The first fixing blocks are located within the first gap.

[0005] Furthermore, the first fixing block is provided with a first working surface and a second working surface. The first fixing block has a first end and a second end. The first working surface and the second working surface are inclined so that the thickness of the first fixing block gradually increases from the first end to the second end. The thickness of the first end of the first fixing block is less than the first gap, and the thickness of the second end of the first fixing block is greater than the first gap.

[0006] Furthermore, a pad is connected to the lower end of the column, and the pad is detachably connected to the column via a first screw.

[0007] Furthermore, the pad is provided with a first through hole.

[0008] Furthermore, a second coil is connected to the substrate, the second coil includes a second spiral tube segment, a second gap is formed between adjacent tubes of the second spiral tube segment, and a plurality of second fixing blocks are connected to the column, the second fixing blocks being located within the second gap.

[0009] Furthermore, the second fixing block is provided with a third working surface and a fourth working surface, and the second fixing block has a third end and a fourth end. The third working surface and the fourth working surface are inclined so that the thickness of the second fixing block gradually increases from the third end to the fourth end. The thickness of the third end of the second fixing block is less than the second gap, and the thickness of the fourth end of the second fixing block is greater than the second gap.

[0010] Furthermore, the first coil includes an inner tube and a sleeve fitted over the inner tube.

[0011] Furthermore, the first bracket is provided in more than one form.

[0012] Furthermore, the pad is provided with a second screw, which is perpendicular to the first screw.

Detailed Implementation

[0015] The present invention will be further illustrated below with reference to specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. Example 1

[0016] like Figure 1 and Figure 3 As shown, a heat exchanger coil structure includes a base plate 1, a first coil 2, and a first support 3. The base plate 1 is a circular plate. In this embodiment, the base plate 1 adopts a flange blind plate. The base plate 1 has multiple bolt holes 11 for connecting the base plate 1 to the flange of an external heat exchanger. The first coil 2 is connected to the base plate 1. The first coil 2 includes a first inlet pipe 21, a first outlet pipe 22, and a first spiral pipe section 23. The first inlet pipe 21 and the first outlet pipe 22 are located above the base plate 1 and penetrate downward through the base plate 1. The first spiral pipe section 23 is located below the base plate 1 and descends in a spiral manner. The top end of the first spiral pipe section 23 is connected to the first inlet pipe 21, and the bottom end of the first spiral pipe section 23 is connected to the first outlet pipe 22 through an upward extension pipe. The first inlet pipe 21 and the first outlet pipe 22 are welded to the base plate 1 at the points where they penetrate the base plate 1. The first coil 2 includes an inner tube 25 and a sleeve 26 fitted outside the inner tube 25. The inner tube 25 is made of C276 Hastelloy with a thickness of 1 mm, and the sleeve 26 is made of existing tantalum-tungsten alloy with a thickness of 0.5 mm, which improves the corrosion resistance of the first coil 2.

[0017] like Figure 1 and Figure 2As shown, the first support 3 is connected to the base plate 1. The first support 3 includes a top plate 31, a column 32, and a plurality of first fixing blocks 33. The top plate 31 is a flat plate and is detachably connected to the base plate 1 by a first bolt 311. The top plate 31 is provided with a strip hole corresponding to the first bolt 311 to facilitate fine adjustment of the left and right positions of the top plate 31. The base plate 1 is provided with a first threaded hole corresponding to the first bolt 311. After tightening the first bolt 311, the top plate 31 is pressed onto the bottom surface of the base plate 1. The column 32 is connected to the top plate 31 and is perpendicular to the top plate 31. The top end of the column 32 is connected to the top plate 31. A plurality of first fixing blocks 33 are connected to the outer wall of the column 32. The plurality of first fixing blocks 33 are distributed from top to bottom on the column 32 and are evenly distributed between each other. Because the first spiral tube segment 23 descends spirally, a first gap 201 is formed between adjacent tubes of the first spiral tube segment 23. The first fixing block 33 is located within the first gap 201. The first fixing block 33 is provided with a first working surface 331 and a second working surface 332. The first working surface 331 is the upper end surface of the first fixing block 33, and the second working surface 332 is the lower end surface of the first fixing block 33. The first fixing block 33 has two ends, namely a first end 333 and a second end 334. The first end 333 is the outer end of the first fixing block 33, and the second end 334 is the outer end of the first fixing block 33. The inner end of the first working surface 331 and the second working surface 332 are inclined so that the thickness of the first fixing block 33 gradually increases from the first end 333 to the second end 334. The thickness of the first end 333 of the first fixing block 33 is less than the thickness of the first gap 201, and the thickness of the second end 334 of the first fixing block 33 is greater than the thickness of the first gap 201. Thus, when the first fixing block 33 is inserted into the first gap 201, the first working surface 331 and the second working surface 332 of the first fixing block 33 gradually contact the tube body of the first spiral tube segment 23, providing support for the tube body of the first spiral tube segment 23. There is one or more first supports 3. In this embodiment, there are two first supports 3. The two first supports 3 are symmetrically arranged to provide good support for the first spiral tube segment 23 of the first coil 2, preventing deformation and damage to the first spiral tube segment 23 after coil transportation or long-term use. In this embodiment, the top plate 31, column 32 and multiple first fixing blocks 33 of the first bracket 3 are all made of polytetrafluoroethylene, which has good corrosion resistance and can be slightly deformed during installation, making it easy to install and can be inserted into the first gap 201.

[0018] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, a pad 34 is connected to the lower end of the column 32. The pad 34 is rectangular. A first screw 341 is provided on one side of the pad 34, and a second screw 343 is provided on one end face of the pad 34. The second screw 343 is perpendicular to the first screw 341. The second screw 343 and the first screw 341 have the same length, diameter and thread. The column 32 has a threaded hole corresponding to the first screw 341. The pad 34 is detachably connected to the column 32 through the first screw 341 or the second screw 343. The side length and height of the pad 34 are different. Different support heights can be obtained by switching the connection between the first screw 341 and the second screw 343 and the column 32. Furthermore, the height can be finely adjusted within a certain range by adjusting the first screw 341 or the second screw 343. When the heat exchanger coil structure is placed into the heat exchanger shell as a whole, the pad 34 can form a support at the bottom. The pad 34 is provided with a first through hole 342. When transporting the entire coil structure, the first through hole 342 can be connected to a binding strap or a fixing rope to fix it and prevent shaking. Example 2

[0019] like Figure 7 , Figure 8 and Figure 9 As shown, the difference from Embodiment 1 is that a second coil 4 is also connected to the substrate 1. The second coil 4 includes a second inlet pipe 41, a second outlet pipe 42, and a second spiral section 43. The second inlet pipe 41 and the second outlet pipe 42 are also disposed on the upper surface of the substrate 1 and extend downward through the substrate 1. The radius of the circle containing the second spiral section 43 is smaller than the radius of the circle containing the first spiral section 23. The second spiral section 43 is located inside the first spiral section 23. A second gap 401 is formed between adjacent tubes of the second spiral section 43. A plurality of second fixing blocks 35 are also connected to the inner sidewall of the column 32. The shape of the second fixing block 35 is the same as that of the first fixing block 33, and the second fixing block 35 is aligned with the first fixing block 33. The second fixing block 35 is located within the second gap 401. The second fixing block 35 has a third working surface 351 and a fourth working surface 352. The second fixing block 35 also has two ends, namely a third end 353 and a fourth end 354. The third working surface 351 and the fourth working surface 352 are inclined so that the thickness of the second fixing block 35 gradually increases from the third end to the fourth end. The thickness of the third end 353 of the second fixing block 35 is less than that of the second gap 401, and the thickness of the fourth end 354 of the second fixing block 35 is greater than that of the second gap 401. This facilitates the second fixing block 35 in supporting the second gap 401 and gradually supporting the second spiral tube section 43, preventing the second spiral tube section 43 from deforming and being damaged after coil transportation or long-term use.

[0020] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
