[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0016] Please see Figures 1-2 This utility model discloses a high-efficiency heat exchange type internal cooling structure for a pressure vessel, including a tank body 1, a heat exchange assembly 2 disposed on the inner wall of the tank body 1, and a reinforcing assembly 3 disposed on the inner wall of the tank body 1, wherein: The heat exchange assembly 2 includes a spiral coil 20, the two ends of which are connected to the tank 1. A spiral plate 21 for heat exchange efficiency is installed on the outer surface of the spiral coil 20. The enhancement component 3 includes an integrated pipe 30, on the outer surface of which multiple connecting pipes 31 are installed. A branch pipe 32 is installed at the other end of the connecting pipe 31, and a branch pipe 32 for further improving the heat exchange efficiency inside the tank is installed at the other end of the branch pipe 32.

[0017] Furthermore, the heat exchange assembly 2 also includes an input pipe 22 and an output pipe 23. The input pipe 22 is installed at one end of the spiral coil 20 and is connected to the spiral coil 20. The output pipe 23 is installed at the other end of the spiral coil 20 and is connected to the spiral coil 20.

[0018] Furthermore, the spiral coil 20 is disposed in the middle of the inner wall of the tank 1, the input pipe 22 extends from one end of the inner wall of the tank 1 to the outer surface of the tank 1 and is fixedly connected to the tank 1, and the output pipe 23 extends from the other end of the inner wall of the tank 1 to the outer surface of the tank 1 and is fixedly connected to the tank 1.

[0019] The tank body 1 is fixed inside the pressure vessel, ensuring that the spiral coil 20 is centrally located and sealed to the inlet pipe 22 and outlet pipe 23. The integrated pipe 30 of the reinforcing assembly 3 is symmetrically installed on both sides of the inner wall of the tank. The connecting pipe 31 and the branch pipe 32 are connected sequentially, and the end of the branch pipe 32 is inserted into the insertion hole 35 of the baffle 34, achieving a seal through the sealing ring 36. The airtightness of all connections is checked to ensure no leakage of the cooling medium. A low-temperature cooling medium, such as water or heat transfer oil, is injected into the spiral coil 20 through the inlet pipe 22. The medium flows along the spiral coil 20 and expands the contact area with the high-temperature materials inside the tank through the spiral plate 21. After absorbing heat, the cooling medium is discharged through the outlet pipe 23, forming a circulation loop. Example 2

[0020] Based on the above embodiment 1, please refer to Figures 3-6 The reinforcing component 3 also includes a baffle 34, which is symmetrically installed on the inner wall of the tank 1. A plurality of insertion holes 35 are provided on one side of the baffle 34, and a sealing ring 36 is provided at both ends of the insertion holes 35.

[0021] Furthermore, the integrated tubes 30 are symmetrically arranged on the inner wall of the tank 1, and each integrated tube 30 corresponds to a baffle 34. The branch pipes 32 are arranged between the two connecting pipes 31. One integrated tube 30 corresponds to the input pipe 22 and is connected to the input pipe 22. The other integrated tube 30 corresponds to the output pipe 23 and is connected to the output pipe 23.

[0022] Furthermore, the integrated tube 30 is connected to the connecting tube 31, the branch tube 32 is connected to the connecting tube 31, and the branch tube 32 is connected to the heat exchange tube 33.

[0023] Furthermore, the outer surface of the baffle 34 is fixedly connected to the inner wall of the tank 1, and each insertion hole 35 corresponds to a branch pipe 32. The branch pipe 32 is inserted into the inner wall of the insertion hole 35, and the inner wall of the sealing ring 36 is in close contact with the outer surface of the insertion hole 35 and with the baffle 34.

[0024] The cooling medium from the inlet pipe 22 enters the integrated pipe 30 on one side simultaneously, and is then distributed to each branch pipe 32 via the connecting pipe 31. Finally, it exchanges heat with the material through the heat exchange pipe 33. The baffle 34 guides the material to form turbulence in the tank, reducing boundary layer thermal resistance. At the same time, the design of the insertion hole 35 of the branch pipe 32 avoids fluid short-circuiting and enhances local heat exchange efficiency.

[0025] It should be noted that a separate temperature sensor can be installed to monitor the temperature of the material inside the tank and the temperature difference between the inlet and outlet of the cooling medium, and to dynamically adjust the flow rate or temperature of the cooling medium to ensure a stable and efficient heat exchange process.

[0026] The working principle and usage process of this utility model are as follows: The tank body 1 is fixed inside the pressure vessel, ensuring that the spiral coil 20 is centrally located and sealed to the input pipe 22 and output pipe 23. The integrated pipe 30 of the reinforcing component 3 is symmetrically installed on both sides of the inner wall of the tank. The connecting pipe 31 and the branch pipe 32 are connected sequentially, and the end of the branch pipe 32 is inserted into the insertion hole 35 of the baffle 34, achieving a seal through the sealing ring 36. The airtightness of all connections is checked to ensure no leakage of the cooling medium.

[0027] Cooling medium injection and circulation: Low-temperature cooling medium, such as water or heat transfer oil, is injected into the spiral coil 20 through the inlet pipe 22. The medium flows along the spiral coil 20 and expands the contact area with the high-temperature material in the tank through the spiral plate 21. After absorbing heat, the cooling medium is discharged through the outlet pipe 23, forming a circulation loop.

[0028] Enhanced component coordination: The cooling medium from the inlet pipe 22 synchronously enters the integrated pipe 30 on one side, and is then distributed to each branch pipe 32 via the connecting pipe 31, finally exchanging heat with the material through the heat exchange pipe 33. The baffle 34 guides the material to form turbulence in the tank, reducing boundary layer thermal resistance. At the same time, the design of the insertion hole 35 of the branch pipe 32 avoids fluid short-circuiting and enhances local heat exchange efficiency.

[0029] Maintenance and cleaning: Regularly check the surface of the spiral plate 21 for scale buildup, keep the heat exchange surface clean by chemical cleaning or mechanical unclogging, replace the aged sealing ring 36, and ensure the sealing performance of the enhanced component 3.
