Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically a stainless steel corrugated coil heat exchanger. Background Technology

[0002] Heat exchangers play a vital role in chemical, petroleum, power, food, and many other industrial production processes. They improve cooling efficiency by rapidly transferring heat from a cold water tank to the cooling medium, thus quickly lowering the water temperature. Corrugated tube heat exchangers are a relatively new type of heat exchanger, replacing the original smooth straight tubes with corrugated heat exchange tubes. This type of heat exchanger increases heat transfer efficiency by 2 to 4 times. The periodic structure of the corrugated heat exchange tubes is much more complex than that of smooth straight tubes, significantly disturbing the fluid inside the tubes and forcing turbulent flow, thereby enhancing the heat transfer capacity of the heat exchange tubes. However, some current heat exchangers are difficult to disassemble, making maintenance inconvenient. Furthermore, the lack of a locking mechanism makes them prone to misoperation and results in poor installation stability. Therefore, this paper addresses these issues through in-depth research.

[0020] 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.

[0021] Example 1: Please refer to Figures 1-5 A stainless steel corrugated coil heat exchanger includes an exchanger body 5, a lead screw 16, and a fixing sleeve 25. An installation cover 2 is installed on one side of the exchanger body 5, and a bottom cover 7 is installed on the other side. A corrugated coil body 3 is installed inside the exchanger body 5 on one side of the installation cover 2. One end of the corrugated coil body 3 is connected to a cold water inlet pipe 4, and the other end is connected to a cold water outlet pipe 8. A hot water inlet pipe 6 is installed on one side above the exchanger body 5, and a hot water outlet pipe 1 is installed below the side of the installation cover 2. A control panel 9 is installed below. A first sealing ring 10 is installed on the inner wall of the mounting cover 2. Screws 16 are evenly installed on the outer wall of one side of the exchanger body 5. A movable sleeve 17 is threaded on the outer wall of each screw 16. A connecting plate 15 is connected to one side of each movable sleeve 17. A locking block 14 is connected to the inner wall of each connecting plate 15. A slot 13 that mates with the locking block 14 is provided on the outer wall of the mounting cover 2. Rotating rods 19 are evenly installed on the outer wall of one side of the exchanger body 5. A fixing sleeve 25 is installed on the outer wall of the exchanger body 5 outside the rotating rod 19.

[0022] Both ends of the outer wall of one side of the switch body 5 are provided with positioning grooves 11, and the inner wall of the mounting cover 2 is connected with positioning blocks 12 that cooperate with the positioning grooves 11.

[0023] The outer wall of one end of the lead screw 16 is equipped with a first bevel tooth 18, and one end of the rotating rod 19 is connected to a second bevel tooth 20. The second bevel tooth 20 and the first bevel tooth 18 form a meshing transmission structure.

[0024] A second sealing ring 21 is installed on the inner side of the bottom cover 7 on the outer wall of the cold water outlet pipe 8. The outer wall of the cold water outlet pipe 8 is provided with an external thread 23. Nuts 22 are threaded on the outer walls of both ends of the cold water outlet pipe 8.

[0025] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when using this structure, the second bevel tooth 20 is rotated by rotating the rotating rod 19. The second bevel tooth 20 meshes with the first bevel tooth 18, causing the lead screw 16 to rotate simultaneously. The threaded engagement causes the connecting plate 15 to move the locking block 14 away from the locking groove 13. Then, the mounting cover 2 can be disassembled to one side. Then, the nut 22 on the side of the cold water outlet pipe 8 is rotated to remove it. After pulling the mounting cover 2 outward, the mounting cover 2 moves the corrugated coil body 3 out at the same time, which facilitates the disassembly and maintenance of the corrugated coil body 3.

[0026] Example 2: Locking sleeves 27 are installed on the outer wall of the fixing sleeve 25, and the inner wall of one side of the locking sleeve 27 is provided with threads, and the outer wall of the fixing sleeve 25 is provided with threads, forming a threaded connection structure between the locking sleeve 27 and the fixing sleeve 25.

[0027] Movable rods 24 are evenly and movably installed on the outer wall of the fixed sleeve 25, and one end of each movable rod 24 is connected to a locking block 26. The outer wall of the rotating rod 19 is provided with a locking groove 29 that cooperates with the locking block 26.

[0028] The other end of each movable rod 24 is connected to a fixed plate 30, and a return spring 28 is installed on the outer wall of each movable rod 24 at one end of the fixed plate 30.

[0029] Specifically, such as Figure 1 , Figure 2 and Figure 5 As shown, when using this structure, after positioning and installing the mounting cover 2, rotate the rotating rod 19 in the opposite direction to make the locking block 14 engage in the locking groove 13 for fixed installation. Rotate the locking sleeve 27, and the threaded engagement will move the locking sleeve 27 to the right. Then, the fixing plate 30 will be pressed against the locking sleeve 27. After the fixing plate 30 is pressed inward, the movable rod 24 will drive the locking block 26 to enter the locking groove 29 at the same time, locking the position of the rotating rod 19.

[0030] Working principle: When using this device, cold water first enters the corrugated coil body 3 through the cold water inlet pipe 4. The corrugated coil body 3 is made of stainless steel and is discharged through the cold water outlet pipe 8. Hot water enters the heat exchanger body 5 through the hot water inlet pipe 6. The corrugations of the corrugated coil body 3 increase the contact area with the hot water, thereby improving the heat exchange efficiency. The cooled water after heat exchange is discharged through the hot water outlet pipe 1.

[0031] Implementation steps for the first innovation point:

[0032] Step 1: Rotate the rotating rod 19 to make the second bevel tooth 20 rotate. The second bevel tooth 20 meshes with the first bevel tooth 18, causing the lead screw 16 to rotate simultaneously. The threaded engagement causes the connecting plate 15 to drive the locking block 14 to move away from the locking groove 13. Then, the mounting cover 2 can be disassembled to one side.

[0033] Step 2: Then rotate the nut 22 on one side of the cold water outlet pipe 8 to remove it. After pulling the mounting cover 2 outward, the mounting cover 2 will move the corrugated coil body 3 out at the same time, which will facilitate the disassembly and maintenance of the corrugated coil body 3.

[0034] Implementation steps for the second innovation point:

[0035] Step 1: After positioning and installing the mounting cover 2, rotate the rotating rod 19 in the opposite direction to make the locking block 14 engage with the locking groove 13 for fixed installation;

[0036] Step 2: Then rotate the locking sleeve 27, threaded engagement, to move the locking sleeve 27 to the right, and then press the fixing plate 30 against the locking sleeve 27. After the fixing plate 30 is pressed inward, the movable rod 24 drives the locking block 26 to enter the locking groove 29 at the same time, locking the position of the rotating rod 19 to avoid misoperation and make the installation more stable.
