Description

Technical Field

[0001] This utility model application relates to the field of plate-fin heat exchanger technology, specifically a plate-fin heat exchanger that can improve heat dissipation. Background Technology

[0002] Plate-fin heat exchangers, as a type of heat exchange equipment, are typically composed of baffles, fins, seals, and guide vanes. Fins, guide vanes, and seals are placed between two adjacent baffles to form a sandwich layer, called a channel. These sandwich layers are stacked according to different fluid flow patterns and brazed into a whole to form a plate bundle. The plate bundle is the core of the plate-fin heat exchanger and is widely used in industries such as petroleum, chemical, and natural gas processing.

[0003] Plate-fin heat exchangers achieve heat exchange by increasing the contact area through fins. However, the limited area of ​​the fins in existing plate-fin heat exchangers results in a limited heat exchange area for the fluid as it passes through, thus limiting the heat dissipation effect of the plate-fin heat exchanger. Summary of the Invention

[0004] To address the problem that the limited contact area of ​​the fins in existing plate-fin heat exchangers affects heat dissipation, this invention provides a plate-fin heat exchanger that improves heat dissipation, thus solving the aforementioned problem.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A plate-fin heat exchanger with improved heat dissipation includes a heat exchanger body and fins. All fins are fitted with a support frame on their outer side. The support frame is slidably fitted inside the heat exchanger body. Both ends of the support frame are fixed with connecting screws. The connecting screws are slidably inserted into movable slots opened on both sides of the heat exchanger body. Each connecting screw has a fixed clamp threaded on one end extending to the outer side of the heat exchanger body. A detachable connecting sleeve frame is fixed inside the support frame on both sides of each fin. A cleaning sponge is fixed to the inner wall of each connecting sleeve frame. The cleaning sponge is slidably attached to the fin surface.

[0007] Furthermore, the width of each of the fixed clamping blocks is greater than the width of the moving slot, and a fixed handle is fixed to the end of each of the connecting screws away from the support frame.

[0008] Furthermore, each of the connecting sleeves and cleaning sponges is configured as a U-shape to cooperate with the fins, and the height of the connecting sleeves and cleaning sponges is less than the height of the support frame.

[0009] Furthermore, a fixed side plate is fixed to the inner wall of the support frame on the outer side of each of the connecting sleeve frames, and a fixed block is fixed to the middle of the outer side of each of the connecting sleeve frames. The fixed blocks are slidably inserted into the fixed side plate, and a fixed rod is slidably inserted into the interior of each fixed block.

[0010] Furthermore, each of the fixed rods inside the fixed side plate is fixed with a movable plate, and each fixed rod outside the movable plate is fitted with a spring, with both ends of each spring fixed to the movable plate and the fixed side plate respectively.

[0011] Furthermore, each of the fixed inserts has a pull plate fixed to one end extending to the outside of the fixed side plate, and each of the fixed side plates has a sliding groove with a diameter larger than that of the fixed insert and which cooperates with the moving plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, by cleaning the fins in a timely manner, dust accumulation on the fin surface is avoided, which reduces the heat dissipation area and ensures the heat exchange effect of the plate-fin heat exchanger during use. This solves the problem that the limited contact area of ​​the fins in existing plate-fin heat exchangers affects the heat dissipation effect, and improves the heat dissipation effect of the plate-fin heat exchanger.

[0014] 2. In this utility model, the detachable cleaning sponge can be removed and washed separately after multiple cleanings. The installation and disassembly are very convenient, making the plate-fin heat exchanger easier and less labor-intensive to maintain during use, and further improving the practicality of the plate-fin heat exchanger.

[0020] To make the purpose, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Reference Figure 1 , Figure 2 and Figure 3 A plate-fin heat exchanger with improved heat dissipation includes a heat exchanger body 1 and fins 2. All fins 2 are fitted with a support frame 3 on their outer side. The support frame 3 is slidably fitted inside the heat exchanger body 1. Connecting screws 4 are fixed at both ends of the support frame 3. The connecting screws 4 are slidably inserted into movable slots 5 opened on both sides of the heat exchanger body 1. A fixing block 6 is threaded onto one end of each connecting screw 4 extending to the outer side of the heat exchanger body 1. The width of each fixing block 6 is greater than the width of the movable slot 5. A fixing handle 7 is fixed to the end of each connecting screw 4 away from the support frame 3. A detachable connecting sleeve frame 8 is fixed inside the support frame 3 on both sides of each fin 2. A cleaning sponge 9 is fixed to the inner wall of each connecting sleeve frame 8. The cleaning sponge 9 slidably adheres to the surface of the fin 2. Each connecting sleeve frame 8 and cleaning sponge 9 is U-shaped to cooperate with the fin 2. The height of the connecting sleeve frame 8 and the cleaning sponge 9 is less than the height of the support frame 3.

[0022] Specifically, when it is necessary to clean the fins 2, twist the fixing blocks 6 on both sides to release the clamping and fixing of the fixing blocks 6 on the heat exchanger body 1. Then, hold the fixing handle 7 and pull down the support frame 3. When the support frame 3 moves, it causes the cleaning sponge 9 to slide on the outer surface of the fins 2, so as to wipe and clean the outer surface of the fins 2 and avoid the dust on the surface of the fins 2 from affecting the heat exchange effect.

[0023] As an optimization solution, such as Figure 2 and Figure 3As shown, a fixed side plate 10 is fixed to the inner wall of the support frame 3 on the outer side of each connecting sleeve frame 8. A fixed block 11 is fixed to the middle of the outer side of each connecting sleeve frame 8. The fixed blocks 11 are slidably inserted into the fixed side plate 10. A fixed rod 12 is slidably inserted into the inside of each fixed block 11. A pull plate 15 is fixed to one end of each fixed rod 12 extending to the outer side of the fixed side plate 10. A movable plate 13 is fixed to the fixed rod 12 inside the fixed side plate 10. A sliding groove with a diameter larger than the fixed rod 12 is opened inside each fixed side plate 10 to cooperate with the movable plate 13. A spring 14 is sleeved on the fixed rod 12 on the outer side of each movable plate 13. Both ends of each spring 14 are fixed to the movable plate 13 and the fixed side plate 10, respectively.

[0024] Specifically, when the cleaning sponge 9 needs to be replaced, first turn the fixing clamp 6 to move the support frame 3 down to the middle of the fin 2, and at the same time push the two pull plates 15 to both sides, so that the pull plates 15 drive the fixing rod 12 to move away from the fin 2 until the fixing rod 12 moves out of the fixing block 11. At this time, the limiting of the fixing rod 12 on the fixing block 11 is released, and the connecting sleeve frame 8 can be pulled up to take out the connecting sleeve frame 8 and the cleaning sponge 9. After cleaning, the connecting sleeve frame 8 and the cleaning sponge 9 are put on the fin 2, and the fixing block 11 is inserted into the fixing side plate 10. Then, the pull plate 15 is released so that the fixing rod 12 is inserted into the fixing block 11.
