[0002] Spiral tube heat exchangers are a new type of industrial equipment used for heat exchange between gases or liquids. They are commonly used on large ships, especially LNG carriers, where they are an important component in cryogenic liquefaction and data center cooling systems.

[0003] The spiral wound tubes inside a spiral heat exchanger not only lengthen the heat exchange tubes but also increase the heat exchange area, resulting in high heat exchange efficiency and heat transfer capacity in actual use. However, problems still exist in practical applications. One is that the spiral wound tubes affect the fluidity of the liquid, leading to uneven heat exchange. Another is that the scale that accumulates inside the spiral wound tubes is difficult to clean. Summary of the Invention

[0004] The purpose of this invention is to provide a marine spiral tube high-efficiency heat exchanger to solve the above-mentioned problems.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a marine spiral tube high-efficiency heat exchanger, comprising a cylindrical body, the cylindrical body being fixedly mounted on a pair of bases, a first partition and a second partition being fixedly mounted inside the cylindrical body, the first partition and the second partition dividing the interior of the cylindrical body into three spaces: a liquid outlet chamber, a heat exchange chamber and a liquid inlet chamber, respectively, and a plurality of holes being opened in both the first partition and the second partition, the holes in the first partition and the second partition being fixedly connected by a plurality of heat exchange tubes;

[0006] A chamber is left at the center of the heat exchange tube. A rotating rod is installed in the chamber. The rotating rod is rotatably positioned between the first partition and the second partition.

[0014] In summary, the present invention has the following beneficial effects:

[0015] 1. This invention leaves a chamber at the center of the heat exchange tube, and a rotating rod is installed in the chamber. The rotating rod is rotatably positioned between a first partition and a second partition. One end of the rotating rod passes through the second partition and is inserted into the liquid inlet chamber. A turbine is fixedly installed on the rotating rod in the liquid inlet chamber, and several stirring rods are fixedly installed on the rotating rod in the chamber. After the first liquid enters the liquid inlet chamber through the liquid inlet, it drives the turbine to rotate. The turbine drives the rotating rod to rotate, and the rotation of the stirring rods causes the second liquid in the heat exchange chamber to flow, so that the second liquid inside and outside the heat exchange tube exchanges and flows, thereby achieving uniform heat exchange and optimizing the heat exchange effect.

[0016] 2. A cleaning chamber with an opening facing the liquid inlet is formed inside the rotating rod. Several cleaning holes communicating with the cleaning chamber are formed on the rotating rod. A sliding extension tube is slidably installed inside the liquid inlet, with a plug fixed at one end of the extension tube. The plug is connected to the liquid inlet. A moving component for controlling the movement of the plug is set on one side of the plug. A baffle is fixed inside the cleaning chamber, and several water inlet grooves are formed through the baffle. The water inlet grooves are blocked by the extension tube. A drain valve is set at the bottom of the heat exchange chamber. When cleaning the scale inside the heat exchange tube, simply control the moving component to drive the plug to move and insert into the liquid inlet. At this time, the water inlet grooves are no longer blocked. Cleaning fluid is introduced into the liquid inlet. The cleaning fluid will enter the plug and extension tube from the liquid inlet, but not into the liquid inlet chamber. The cleaning fluid will enter the cleaning chamber through the water inlet grooves and finally spray out from each cleaning hole, thereby cleaning the scale on the heat exchange tube from the inside out, greatly increasing the cleaning effect, facilitating the cleaning of scale on the surface of the heat exchange tube, and ensuring that the heat exchanger always maintains a good heat exchange effect.

Cleaning hole Detailed Implementation

[0029] Example 1:

[0030] Combined with appendix Figures 1-10 The marine spiral tube high-efficiency heat exchanger includes a cylindrical body 11, which is fixedly mounted on a pair of bases 12. A first partition 20 and a second partition 22 are fixedly mounted inside the cylindrical body 11, which divide the interior of the cylindrical body 11 into three spaces: a liquid outlet chamber 19, a heat exchange chamber 26, and a liquid inlet chamber 27.

[0031] Wherein, a liquid outlet 13 is fixedly provided on one side of the cylinder 11, and the liquid outlet 13 is fixedly connected to the liquid outlet chamber 19; a liquid inlet 14 is fixedly provided on the other side of the cylinder 11, and the liquid inlet 14 is fixedly connected to the liquid inlet chamber 27; a liquid outlet pipe 15 and a liquid inlet pipe 16 are fixedly provided on the top of the cylinder 11, and the liquid outlet pipe 15 and the liquid inlet pipe 16 are fixedly connected to the heat exchange chamber 26;

[0032] Several holes are made on both the first partition plate 20 and the second partition plate 22. Several heat exchange tubes 24 are fixedly connected between the holes of the first partition plate 20 and the second partition plate 22, and each heat exchange tube 24 is spirally wound.

[0033] During heat exchange, a first liquid enters the inlet chamber 27 through the inlet 14, flows through each of the heat exchange tubes 24 to the outlet chamber 19, and is finally discharged from the outlet 13; a second liquid enters the heat exchange chamber 26 through the outlet pipe 15 and is finally discharged from the inlet pipe 16; the first liquid in the heat exchange tubes 24 and the second liquid in the heat exchange chamber 26 exchange heat, with the heat being conducted by the shell of the heat exchange tubes 24;

[0034] A chamber is provided at the center of the heat exchange tube 24. A rotating rod 29 is installed in the chamber. The rotating rod 29 is rotatably disposed between the first partition 20 and the second partition 22. One end of the rotating rod 29 passes through the second partition 22 and is inserted into the liquid inlet chamber 27. A turbine 28 is fixedly installed on the rotating rod 29 in the liquid inlet chamber 27. Several stirring rods 30 are fixedly installed on the rotating rod 29 in the chamber.

[0035] It should be noted that a waterproof component should be added or waterproof treatment should be applied between the rotating rod 29 and the second partition plate 22 (generally, a waterproof bearing and waterproof adhesive can be used) to prevent the liquid in the liquid inlet chamber 27 from mixing with the liquid in the heat exchange chamber 26.

[0036] After the first liquid enters the inlet chamber 27 through the inlet 14, it drives the turbine 28 to rotate. The turbine 28 drives the rotating rod 29 to rotate, and the rotating stirring rod 30 drives the second liquid in the heat exchange chamber 26 to flow, so that the second liquid inside and outside the heat exchange tube 24 exchanges and flows, thereby achieving uniform heat exchange and optimizing the heat exchange effect.

[0037] Example 2:

[0038] The difference between this embodiment and Embodiment 1 is that a cleaning chamber 31 with an opening facing the liquid inlet chamber 27 is opened inside the rotating rod 29, and a plurality of cleaning holes 44 communicating with the cleaning chamber 31 are opened on the rotating rod 29. At least two sliding grooves 35 are opened at one end of the rotating rod 29 inside the liquid inlet chamber 27, and sliding strips 36 are slidably arranged in each of the sliding grooves 35. The sliding strips 36 are all fixedly arranged on the extension tube 37, and a plug 32 is fixed at one end of the extension tube 37.

[0039] The inner diameter of the plug 32 is the same as that of the liquid inlet 14. A moving component for controlling the movement of the plug 32 is provided on one side of the plug 32. A baffle 42 is fixed in the cleaning chamber 31. Several water inlet grooves 43 are opened through the baffle 42. The water inlet grooves 43 are blocked by the extension tube 37.

[0040] A drain valve 49 is provided at the bottom of the heat exchange chamber 26;

[0041] To enhance the sealing effect, a sealing sheet 34 is fixed on the side of the extension pipe 37 near the water inlet 43. The sealing sheet 34 is made of rubber and has good waterproof effect.

[0042] Several sealing rings 33 are fixed on the plug 32. The sealing rings 33 are made of rubber and are used to enhance the sealing performance.

[0043] To clean the scale inside the heat exchange tube 24, simply control the moving component to drive the plug 32 to move and insert into the liquid inlet 14. At this time, the water inlet 43 is no longer blocked. Cleaning fluid is introduced into the liquid inlet 14. The cleaning fluid will enter the plug 32 and the extension tube 37 from the liquid inlet 14, but will not enter the liquid inlet chamber 27. The cleaning fluid will enter the cleaning chamber 31 through the water inlet 43 and finally spray out from each of the cleaning holes 44, thereby cleaning the scale on the heat exchange tube 24 from the inside out, greatly increasing the cleaning effect.

[0044] After soaking in the cleaning solution for a period of time, clean water is introduced into the heat exchange chamber 26 through the liquid inlet pipe 16 until it is full. After it is full, the drain valve 49 is opened to drain the sewage along with the scale. This process is repeated several times to complete the cleaning.

[0045] This makes it very convenient to clean the scale on the surface of the heat exchange tube 24, so that the heat exchanger always maintains a good heat exchange effect.

[0046] The movable component includes an annular groove formed on the surface of the extension tube 37, a rotating ring 38 rotatably mounted on the annular groove, a connecting strip 39 fixed on the rotating ring 38, a telescopic rod 40 fixed on one side of the connecting strip 39, the telescopic rod 40 being controlled to extend and retract by a telescopic controller 18, the telescopic controller 18 being fixed on a fixed base 41, and the fixed base 41 being fixed on the outside of the cylinder 11.

[0047] It should be noted that the telescopic controller 18 should be a waterproof model, and a control box 17 should be fixedly installed on the base 12 to control the operation of the telescopic controller 18.

[0048] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand and implement the present invention. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
