Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically to a high-efficiency, safe and reliable plate-fin heat exchanger. Background Technology

[0002] Aluminum plate-fin heat exchangers are efficient and lightweight heat exchange devices made of aluminum alloy. They are characterized by their light weight, compact structure, and high heat transfer efficiency. Compared with traditional shell-and-tube heat exchangers, aluminum plate-fin heat exchangers have advantages in terms of higher heat transfer coefficient and smaller space occupation, making them suitable for applications requiring efficient heat dissipation in space-constrained situations. Most existing plate-fin heat exchangers consist of heat dissipation fins fixedly installed on the outer wall of metal pipes. Over long-term use, because the heat dissipation fins are inconvenient to remove, dust, lint, and other debris accumulate in the gaps between the fins, reducing heat exchange efficiency over time. Utility Model Content

[0003] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0004] In view of the problems existing in the above and / or existing high-efficiency, safe and reliable plate-fin heat exchangers, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a high-efficiency, safe, and reliable plate-fin heat exchanger. During use, multiple first heat exchange fins, multiple corrugated heat dissipation plates, and multiple second heat exchange fins are arranged sequentially inside the outer casing. Limiting is achieved through the engagement of a limiting boss and a second limiting groove. Rotating the handwheel causes the fixing plates at both ends of the fixing frame to slide along the first limiting groove through the engagement of a first lead screw and an internal threaded through hole. Tightening is achieved through the engagement of a spring and a pressure plate. Rotating the locking nut locks the connection, ensuring that the first outlet at the top of the multiple second heat exchange fins aligns with the bottom of the multiple first heat exchange fins. The first inlet connection, along with the first and second sealing rubber rings, improves the sealing performance to some extent. High-temperature liquid flows into multiple hollow layers through the inlet pipe, increasing the contact area between the high-temperature liquid and the heat exchange fins compared to traditional metal pipes, thus improving the heat exchange efficiency between the liquid and the heat exchange fins. The corrugated heat exchange plate increases the contact area between the air and the heat exchange fins, further improving the heat exchange efficiency between the heat exchange fins and the air. It is also easy to disassemble; after loosening the locking nut and removing the fixing plate, multiple first heat exchange fins, multiple corrugated heat exchange fins, and multiple second heat exchange fins can be removed one by one for cleaning.

[0014] As a preferred embodiment of the efficient, safe and reliable plate-fin heat exchanger described in this utility model, one end of the pressure plate is horizontally fixedly connected to a water inlet pipe, one end of the water inlet pipe passes through the fixed plate and is provided with a first external thread on the outside, one end of the water inlet pipe is fixedly connected to a second sealing rubber ring, and one bottom end of the outer shell is fixedly connected to a water outlet pipe, one end of the water outlet pipe is provided with a second external thread on the outside.

[0015] As a preferred embodiment of the efficient, safe, and reliable plate-fin heat exchanger described in this utility model, the bottom of the outer shell is provided with multiple second protrusions, each of which has a longitudinally arranged mounting hole.

The first and second sealing rubber rings improve the sealing performance to a certain extent. High-temperature liquid flows into the multiple hollow layers through the inlet pipe, increasing the contact area between the high-temperature liquid and the heat exchange fins compared to traditional metal pipes, thus improving the heat exchange efficiency between the liquid and the heat exchange fins. The shaped heat exchange plate increases the contact area between the air and the heat exchange fins, improving the heat exchange efficiency between the fins and the air. It is also easy to disassemble. After loosening the locking nut and removing the fixing plate, multiple first heat exchange fins, multiple corrugated heat exchange plates, and multiple second heat exchange fins can be removed one by one for cleaning. The water inlet pipe can be quickly connected to the external power component through the first external thread for transporting high-temperature liquids. The second external thread also facilitates quick connection to external pipes for discharging the liquid after heat exchange. External screws can be used to fix the outer shell through the mounting holes. This solves the problem that most existing plate-fin heat exchangers are composed of heat exchange fins fixed to the outer wall of metal pipes. During long-term use, the heat exchange fins are inconvenient to disassemble, and dust, lint, and other debris accumulate in the gaps between multiple fins for airflow, thus reducing the heat exchange effect over time.

The outer side of the first lead screw 11 is threadedly connected to one end of the fixing frame 24. One end of the first lead screw 11 passes through one side of the shell 1 and is fixedly connected to a second lead screw 7. One end of the second lead screw 7 is fixedly connected to a handwheel 9. A locking nut 8 is threadedly connected to the outer side of the second lead screw 7. A clamping assembly is provided on one side of the fixing plate 2.

[0023] A limiting slide rod 27 is fixedly connected to one side of the fixed plate 2. The top and bottom of the outer shell 1 are provided with first limiting grooves 13, and the limiting slide rod 27 is located in the first limiting grooves 13.

[0024] The first heat exchange fin 4, the corrugated heat dissipation plate 5, and the second heat exchange fin 6 are all provided with second limiting grooves 17 at both ends, and limiting bosses 14 are provided on both sides inside the outer shell 1.

[0025] Both the first heat exchange fin 4 and the second heat exchange fin 6 have a hollow layer 22 inside, and both the bottom of one side of the first heat exchange fin 4 and the top of one side of the second heat exchange fin 6 have a first water outlet 19.

[0026] A first water inlet 23 is provided on the top of one side of the first heat exchange fin 4 and the bottom of one side of the second heat exchange fin 6, and a first sealing rubber ring 20 is fixedly connected to one side of the first water outlet 19.

[0027] The first heat exchange fin 4, the corrugated heat dissipation plate 5, and the second heat exchange fin 6 are all provided with a first clearance groove 18 in the middle, and the first lead screw 11 is located in the middle of the first clearance groove 18.

[0028] The waveform heat sink 5 has a second relief groove 21 at both ends, and the first water outlet 19 is located in the second relief groove 21.

[0029] The clamping assembly includes multiple pressure plates 3. Multiple guide posts 29 are fixedly connected to one side of the pressure plate 3. One end of the guide post 29 passes through the fixed plate 2 and is fixedly connected to a limit block 30. Multiple springs 31 are provided between one side of the pressure plate 3 and one side of the fixed plate 2.

[0030] One end of the pressure plate 3 is horizontally fixedly connected to a water inlet pipe 32. One end of the water inlet pipe 32 passes through the fixed plate 2 and is provided with a first external thread 33 on the outside.

[0032] Specifically, multiple first heat exchange fins 4, multiple corrugated heat dissipation plates 5, and multiple second heat exchange fins 6 are arranged sequentially inside the outer casing 1. They are positioned by the engagement of a limiting boss 14 and a second limiting groove 17. Rotating the handwheel 9 causes the fixing plates 26 at both ends of the fixing frame 24 to slide along the first limiting groove 13 through the engagement of the first lead screw 11 and the internal threaded through hole 25.

High-temperature liquid flows into the multiple hollow layers 22 through the inlet pipe 32. Compared to traditional metal pipes, this increases the contact area between the high-temperature liquid and the heat exchange fins, improving the heat exchange efficiency between the liquid and the heat exchange fins. The corrugated heat exchange plate 5 increases the contact area between the air and the heat exchange fins, improving the heat exchange efficiency between the heat exchange fins and the air. It is also easy to disassemble. After loosening the locking nut 8 and removing the fixing plate 26, multiple first heat exchange fins 4, multiple corrugated heat exchange plates 5, and multiple second heat exchange fins 6 can be removed one by one for cleaning. The water inlet pipe 32 can be quickly connected to an external power assembly via the first external thread 33 for transporting high-temperature liquids. The second external thread 10 also facilitates quick connection to external pipes for discharging the liquid after heat exchange. External screws can be used to fix the outer casing 1 through the mounting hole 16. This solves the problem that most existing plate-fin heat exchangers consist of heat exchange fins fixed to the outer wall of metal pipes. During long-term use, the heat exchange fins are difficult to disassemble, and dust, lint, and other debris accumulate in the gaps between the fins for airflow, thus reducing the heat exchange effect over time.

In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this utility model can be combined with each other in any way.
