Description

Technical Field

[0001] This utility model relates to the field of heat exchanger assembly technology, and in particular to a heat exchanger assembly that is easy to clean. Background Technology

[0002] In industrial production and energy conversion, heat exchanger units, as key equipment for heat transfer between different media, are widely used in many industries such as chemical, power, and refrigeration. Their efficiency directly affects the energy consumption and operational stability of the entire production system, and the cleanliness of the equipment is one of the important factors in ensuring heat exchange efficiency. With the expansion of production scale and the increasing demands on processes, higher requirements are being placed on the ease of cleaning heat exchanger units.

[0003] Existing heat exchanger assemblies typically employ a combination of multiple fixedly connected tanks and pipes. The underlying principle is based on the flow of fluids at different temperatures within the tanks and pipes, exchanging heat through the walls of these components. Specifically, a main tank serves as the primary heat exchange space, and it is fixedly connected to multiple auxiliary pipes using welding or bolting. The other end of each auxiliary pipe is then connected to an external fluid transport system, forming a closed heat exchange fluid channel. During operation, the high-temperature and low-temperature fluids flow within their respective channels, transferring heat through conduction across the walls, thus completing the heat exchange process.

[0004] However, in existing technologies, the second liquid tank and the main structure of the heat exchanger assembly are fixedly connected, such as by welding or rigid fastening with multiple bolts. When cleaning the second liquid tank, it is necessary to first disassemble a large number of connecting bolts, and sometimes even cut the welded parts to separate it from the main structure. This process not only requires various specialized tools and consumes a lot of manpower and time, but also easily damages the connecting parts during disassembly, making it impossible to quickly disassemble the second liquid tank, greatly extending the cleaning cycle and seriously affecting the maintenance efficiency of the equipment. Therefore, a heat exchanger assembly that is easy to clean is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a heat exchanger assembly that is easy to clean, aiming to improve the problem in the prior art that the second liquid tank cannot be quickly disassembled, the disassembly process is complicated and time-consuming, resulting in a longer cleaning cycle and affecting the equipment maintenance efficiency.

[0014] The rebound assembly includes a first spring, one end of which is fixedly connected to the side wall of the first sliding ring, and the other end of which is fixedly connected to the inner wall of the first hollow column.

[0015] As a further description of the above technical solution:

[0016] A second sliding groove is provided inside the cold water inlet pipe, and a filter screen is slidably connected inside the cold water inlet pipe.

[0017] As a further description of the above technical solution:

[0018] A clamping plate is fixedly connected to the outer wall of the filter screen, and the side wall of the clamping plate is slidably connected inside the second groove. A second hollow column is fixedly connected to the outer wall of the cold water inflow pipe.

Detailed Implementation

[0036] 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.

[0037] Reference Figures 1-6 An embodiment of this utility model provides a heat exchanger assembly that is easy to clean, including a support 2, a first liquid tank 1 fixedly connected to the top of the support 2, a first fixing ring 3 fixedly connected to the outer wall of the first liquid tank 1, and a slot 12 and a first sliding groove 13 provided inside the first fixing ring 3. A second liquid tank 27 is provided at one end of the first liquid tank 1, and a second fixing ring 4 is fixedly connected to the outer wall of the second liquid tank 27. A quick-release assembly is provided inside the second fixing ring 4.

[0038] The quick-release assembly includes a first hollow column 14, the outer wall of which is slidably connected to the inner wall of a second fixing ring 4. A handle 15 is slidably connected inside the first hollow column 14. Pulling the handle 15 disengages the locking pin 19 from the locking groove 12, and rotating the handle 15 disengages the locking pin 19 from the first sliding groove 13, achieving quick separation of the first liquid tank 1 and the second liquid tank 27 for easy cleaning and maintenance. A first sliding ring 16 is fixedly connected to the outer wall of the handle 15, and a spring-loaded component is provided on the side wall of the first sliding ring 16. A fixing post 18 is fixedly connected to one end of the handle 15, and a locking pin 19 is fixedly connected to the outer wall of the fixing post 18. A hot water inlet pipe 6 and a hot water outlet pipe 8 are fixedly connected to the outer wall of the first liquid tank 1, and a cold water inlet pipe 5 and a cold water outlet pipe 7 are fixedly connected to the outer wall of the second liquid tank 27. Multiple baffles 11 are fixedly connected to the inner wall of the first liquid tank 27. The baffles 11 work with the U-shaped connecting pipe 10 to guide turbulent flow. By extending the path of the high-temperature fluid and disrupting its flow state, the heat exchange efficiency is improved. At the same time, the U-shaped pipe structure increases the effective heat exchange area. Each baffle 11 is fixedly connected to the inner wall of the second liquid tank 27. A baffle 9 is fixedly connected inside the second liquid tank 27. The baffle 9 and the inner cavity of the second liquid tank 27 form a flow guiding channel, which forces the low-temperature fluid to flow around the outer wall of the U-shaped connecting pipe 10. This achieves the effect of full contact between the hot and cold fluids in opposite directions, which improves the heat exchange efficiency compared with the traditional straight-through structure. The rebound component includes a first spring 17. One end of the first spring 17 is fixedly connected to the side wall of the first sliding ring 16, and the other end of the first spring 17 is fixedly connected to the inner wall of the first hollow column 14.

[0039] Reference Figure 1 , Figure 7 and Figure 8 A second sliding groove 26 is provided inside the cold water inlet pipe 5. A filter screen 24 is slidably connected inside the cold water inlet pipe 5. A retaining plate 25 is fixedly connected to the outer wall of the filter screen 24. The side wall of the retaining plate 25 is slidably connected inside the second sliding groove 26. A second hollow column 21 is fixedly connected to the outer wall of the cold water inlet pipe 5. A handle 20 is slidably connected to the inner wall of the second hollow column 21. By grasping the handle 20 and compressing the second spring 22, the bottom of the handle 20 is disengaged from the retaining plate 25, allowing the filter screen 24 to be easily pulled out for cleaning or replacement. During installation... The restoring force of the second spring 22 causes the bottom of the handle 20 to re-engage with the top of the plate 25, ensuring the accurate positioning of the filter screen 24 and its ability to withstand fluid pressure. The outer wall of the handle 20 is slidably connected to the inside of the second hollow column 21. A second sliding ring 23 is fixedly connected to the outer wall of one end of the handle 20. A second spring 22 is provided on the side wall of the second sliding ring 23. One end of the second spring 22 is fixedly connected to the inside of the second hollow column 21, and the other end of the second spring 22 is fixedly connected to the outer wall of the handle 20. The bottom of the handle 20 is slidably connected to the top of the plate 25.

[0040] Working principle: During operation, high-temperature fluid enters the first liquid tank 1 through the hot water inlet pipe 6. Due to the obstruction of multiple internal baffles 11, the flow path is significantly extended, allowing the high-temperature fluid to have more thorough contact with the U-shaped connecting pipe 10, thereby improving heat exchange efficiency. The U-shaped connecting pipe 10 passes through the baffles 11 and connects to the second liquid tank 27, forming a complete heat exchange channel. Low-temperature fluid enters the second liquid tank 27 from the cold water inlet pipe 5 and is first filtered by the filter screen 24, which intercepts impurities in the liquid, preventing them from entering subsequent flow channels and causing blockages. The filtered low-temperature fluid, guided by baffle 9, flows orderly through the outside of the U-shaped connecting pipe 10, transferring heat between the fluid and the high-temperature fluid inside the pipe 10 via the pipe wall. The baffle 11 not only extends the flow path of the high-temperature fluid but also disrupts its flow pattern, ensuring more uniform and comprehensive contact with the U-shaped connecting pipe 10. Baffle 9 ensures the low-temperature fluid flows along a predetermined path within the second liquid tank 27, guaranteeing complete coverage of the U-shaped connecting pipe 10 and further enhancing heat exchange efficiency. Finally, the high-temperature fluid, after heat exchange, is discharged through the hot water outlet pipe 8, and the low-temperature fluid is discharged through the cold water outlet pipe 7, achieving a highly efficient and stable heat exchange cycle.

[0041] Pulling the handle 15 will cause the fixed post 18 and the locking post 19 at one end to move outward. At the same time, the first sliding ring 16, which is fixedly connected to the outer wall of the handle 15, will slide inside the first hollow post 14 and compress the first spring 17. After the locking post 19 disengages from the locking groove 12, the handle 15 will be rotated to completely disengage the side wall of the locking post 19 from the first sliding groove 13. At this time, the first liquid tank 1 and the second liquid tank 27 can be easily separated, which facilitates the thorough cleaning of the inside of the first liquid tank 1, the inside of the second liquid tank 27, and the U-shaped connecting pipe 10.

[0042] When maintaining the filtration system, the operator first grasps the handle 20 and moves it, causing the second sliding ring 23 to slide within the second hollow column 21 and compress the second spring 22. After the handle 20 moves, its bottom disengages from the retaining plate 25 of the filter screen 24. At this point, the operator can horizontally pull out the entire filter screen 24 assembly along the second slide groove 26 for cleaning or replacement. During installation, the cleaned filter screen 24 is pushed into place along the second slide groove 26. After releasing the handle 20, the restoring force of the second spring 22 pushes the handle 20 down, causing its bottom to re-engage with the top of the retaining plate 25. This ensures the accurate positioning of the filter screen 24 and allows it to withstand fluid pressure without shifting, thus filtering the liquid. At the same time, the filter screen 24 can be quickly removed.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
