Description

Technical Field

[0001] This utility model belongs to the technical field of plate-fin heat exchangers, and in particular, it relates to a head structure for an aluminum plate-fin heat exchanger. Background Technology

[0002] The end caps are a crucial component of aluminum plate-fin heat exchangers. Besides collecting the medium and connecting the core and process piping, their most important function is to guide the fluid flow, working in conjunction with the guide vanes. They also play a vital role in fluid distribution within the heat exchanger core. One end cap connects to the inlet pipe, responsible for initial pressure equalization and distribution of the incoming flow; the other end cap (which can be called a secondary end cap or core connector) is directly connected to the heat exchanger core. The two end cap components are mechanically assembled using flanges and bolts, with a sealing gasket placed between their interfaces. The advantage of this split structure is that it allows for the flexible placement of specialized guide vanes, flow equalization orifice plates, or other distribution elements within the cavity formed by the two end cap components. Through multi-stage rectification, the uniformity of fluid distribution is significantly improved.

[0003] The current aluminum plate-fin heat exchanger head structure has certain tolerances during processing. Deviations in the processing dimensions of components such as the head end plate and vent joint, as well as insufficient control of the surface roughness of the sealing groove, can cause the gasket to fail to completely fill the sealing groove, forming a leakage channel. This can lead to loose connections and affect operation.

[0004] Therefore, in view of this situation, there is an urgent need to design and manufacture a head structure for aluminum plate-fin heat exchangers to meet the needs of practical use. Utility Model Content

[0005] The purpose of this utility model is to provide a head structure for an aluminum plate-fin heat exchanger to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a head structure for an aluminum plate-fin heat exchanger, comprising a first head and a second head for use in an aluminum plate-fin heat exchanger, a first support plate fixedly connected to the side of the second head, a first knob rotatably connected to the surface of the first support plate, a threaded shaft fixedly connected to the side of the first knob, a first movable plate screwed to the side of the threaded shaft, a limit rod slidably connected to the side of the first movable plate, the side of the limit rod being fixed to the side of the first support plate, and a second support plate fixedly connected to the side of the first head.

[0007] Preferably, a sliding rod is slidably connected to the side of the second support plate, and a connecting block is fixedly connected to the end of the sliding rod.

[0008] Preferably, a second movable plate is fixedly connected to the side of the sliding rod, and a handle is fixedly connected to the side of the second movable plate away from the sliding rod.

[0009] Preferably, a return spring is sleeved on the outer wall of the sliding rod, and the end of the return spring is welded to the lower side of the second moving plate.

[0010] Preferably, the side of the reset spring is welded to the side of the second support plate, and the side of the first end cap is fixedly connected to the liquid inlet pipe.

[0011] Preferably, an isolation plate is fixedly connected to the inner side of the first end cap, and a locking block is fixedly connected to the side of the second end cap.

[0012] Preferably, the locking block engages with the first end cap.

[0013] Preferably, the side of the first movable plate is screwed with fixing bolts.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are as follows: The end cap structure of this aluminum plate-fin heat exchanger uses fixing bolts to screw together the first and second moving plates. Simultaneously, fixing bolts connect the first support plate and the connecting block. A first knob drives the threaded shaft to rotate, which in turn moves the first moving plate, bringing the first and second end caps closer together until they are fully fitted. This prevents any tolerances between the first and second end caps, which could result in gaps and affect the efficiency of the end caps in the aluminum plate-fin heat exchanger.

[0021] To address the issue of dimensional deviations in the machining of components such as end plates and vent joints due to inherent tolerances during processing, as well as insufficient control over the surface roughness of the sealing groove, which can lead to incomplete filling of the sealing groove by the gasket, creating leakage channels, resulting in loose connections and affecting operation, such as... Figures 1 to 5 The diagram shows a head structure for an aluminum plate-fin heat exchanger, including a first head 2 and a second head 3 for use in an aluminum plate-fin heat exchanger. The outer wall of the second head 3 is provided with a connecting pipe for easy connection to the heat exchanger core. A first support plate 4 is fixedly connected to the side of the second head 3. A first knob 5 is rotatably connected to the surface of the first support plate 4. A threaded shaft 6 is fixedly connected to the side of the first knob 5. A first movable plate 9 is screwed to the side of the threaded shaft 6. A limit rod 8 is slidably connected to the side of the first movable plate 9. The side of the limit rod 8 is fixed to the side of the first support plate 4. A second support plate 13 is fixedly connected to the side of the first head 2.

[0022] The second support plate 13 is slidably connected to a sliding rod 15 on its side. A connecting block 14 is fixedly connected to the end of the sliding rod 15. A second moving plate 17 is fixedly connected to the side of the sliding rod 15. The first moving plate 9 is moved by the rotation of the threaded shaft 6, which drives the first end cap 2 and the second end cap 3 to move closer together until the first end cap 2 and the second end cap 3 are in contact. A handle 18 is fixedly connected to the side of the second moving plate 17 away from the sliding rod (15).

[0023] A return spring 16 is sleeved on the outer wall of the sliding rod 15. The side of the return spring 16 is welded to the lower side of the second moving plate 17, and the end of the return spring 16 is welded to the side of the second support plate 13. A liquid inlet pipe 1 is fixedly connected to the side of the first end cap 2, and an isolation plate 11 is fixedly connected to the inner side of the first end cap 2. The isolation plate 11 has multiple liquid permeable holes through it along its own thickness direction. The fluid medium can enter the end cap of the aluminum plate-fin heat exchanger through the liquid inlet pipe and pass through the liquid permeable holes through the isolation plate 11. The isolation plate 11 has the function of making the fluid medium flow evenly. A locking block 12 is fixedly connected to the side of the second end cap 3. The locking block 12 is locked to the first end cap 2. A fixing bolt 10 is screwed to the side of the first moving plate 9.

[0024] All structures and instruments are treated with heat-resistant and waterproof materials.

[0025] Working principle The aluminum plate-fin heat exchanger uses a head structure. During use, the locking block 12 is engaged with the first head 2. The first moving plate 9 and the second moving plate 17 are screwed together and fixed by the fixing bolts 10. At the same time, the first support plate 4 and the connecting block 14 are connected by the fixing bolts 10. Then, the first knob 5 drives the threaded shaft 6 to rotate. The rotation of the threaded shaft 6 drives the first moving plate 9 to move, bringing the first head 2 and the second head 3 closer together until the first head 2 and the second head 3 are in contact. After the first head 2 and the second head 3 are disassembled and separated, the reset contact 16 drives the second moving plate 17 to spring back.
