Technical Field

[0001] The present invention relates to the field of heat exchanger equipment, and specifically to a flat-tube water-cooled parallel-flow heat exchanger. Background Technique

[0002] In a ship, the heat exchanger plays an important cooling role. Its heat exchange principle comes from the microchannel theory. The left header and the right header are respectively inserted at both ends of the flat tube. However, nowadays, the water flow in the parallel-flow heat exchanger is directly discharged after being cooled once, and effective rapid cooling cannot be carried out.

[0003] According to a water-cooled parallel-flow heat exchanger with multiple rows of flat tubes disclosed in a patent document with the existing publication number CN216205476U, it includes a first connecting member, which includes a lower base, a first limiting hole opened at the top of the lower base, a vertical plate installed at the inner bottom of the lower base, a first baffle installed at the top of the vertical plate and located inside the lower base, a first through groove opened at the top of the first baffle, and a flat tube passing through the first through groove; a second connecting member, which includes a side plate installed at the top of the lower base and a heat dissipation plate installed in the middle of the side plate. When this technical solution is in use, the gear structure drives the threaded rod to rotate, and the fixing block horizontally extends into the positioning hole of the fixing box on the threaded rod body and extends into the inner parts of the upper and lower base shells to complete the limit fixation. At the same time, the side plate and the heat dissipation plate are combined through the chute structure, which is convenient for cleaning and replacing the heat dissipation plate. For the above technical solution, although the cleaning and replacement are achieved, the flow rate of the high-temperature liquid in the flat tube cannot be reduced during use, the contact area with the heat absorption structure cannot be increased during its flow, and there are inconveniences during use. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a flat-tube water-cooled parallel-flow heat exchanger to solve the problems raised in the above background technique. The structure of the present invention is novel. During use, the fin plate is installed inside the arc-shaped groove, and the fin plate is supported and limited by the fixing column. The fin plate and the arc-shaped groove cooperate with each other for limit fixation. At the same time, an arc-shaped plate is installed at the position of the arc-shaped groove, and the arc-shaped plate reduces the flow rate of the high-temperature liquid in the flat tube. The fin plate installed inside the arc-shaped groove effectively increases the contact area with the flat tube, and better completes the heat absorption and dissipation of the high-temperature liquid.

[0005] To achieve the above object, the present invention is realized by the following technical solutions: A flat-tube water-cooled parallel flow heat exchanger, comprising a fixed seat and a support seat.

DETAILED DESCRIPTION OF THE INVENTION

[0018] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0019] Please refer to Figures 1 to 8 , the present invention provides a technical solution: a flat-tube water-cooled parallel-flow heat exchanger, including a fixed seat 1 and a support seat 2. An installation seat 6 is movably installed on the side of the fixed seat 1 and the support seat 2. A protective plate 7 is welded between the installation seats 6. A cold water pipe 9 is fixedly installed on the installation seat 6. A flat tube 10 is installed on one side of the cold water pipe 9. An arc-shaped groove 11 is opened on the flat tube 10. A fixing column 13 is fixed inside the arc-shaped groove 11. A fin plate 12 is movably installed between the fixing column 13 and the arc-shaped groove 11. A threaded hole 14 is opened on the fixing column 13. A limit bolt 15 is rotatably installed inside the threaded hole 14. The diameter of the limit bolt 15 is larger than that of the fixing column 13. The fin plate 12 is squeezed and fixed by the installation of the limit bolt 15.

[0020] In this embodiment, the diameter of the limit bolt 15 is larger than that of the fixing column 13. The inner wall of the limit bolt 15 is movably in contact with the side of the fin plate 12. A movable plate 3 is fixed on the top of the fixed seat 1. A water inlet pipe 4 is fixedly installed on the movable plate 3. A flow distribution box 18 is fixed on the inner wall of the movable plate 3. One end of the water inlet pipe 4 is installed on the flow distribution box 18. A fixing bolt 8 is rotatably installed on the inner wall of the installation seat 6. One end of the fixing bolt 8 is rotatably installed on the fixed seat 1 and the support seat 2. Rubber rings are fixed on the inner walls of the fixed seat 1 and the support seat 2. The fixing bolt 8 installs the fixed seat 1 and the support seat 2 on the installation seat 6, which is convenient for the quick disassembly of the fixed seat 1 and the support seat 2 in the later stage.

[0021] In this embodiment, a through hole 17 is opened on the cold water pipe 9. A cavity 22 is opened inside the flat tube 10. An opening 16 is opened at one end of the cavity 22. The opening 16 and the through hole 17 are distributed in a left-right staggered manner. A flow distribution pipe 19 is welded at the bottom of the flow distribution box 18. A ring seat 20 is fixed on the flow distribution pipe 19. The flow distribution pipe 19 is movably installed inside the through hole 17. A connection hole 21 is opened on the flow distribution pipe 19. The connection hole 21 is movably installed inside the through hole 17. The ring seat 20 is movably installed at the inner wall of the through hole 17. The flow distribution pipe 19 is movably in contact with one end of the flat tube 10. After the flow distribution pipe 19 is in contact with one end of the flat tube 10, the flat tube 10 is limited and fixed.

[0022] In this embodiment, an arc-shaped plate 23 is fixed inside the flat tube 10. The arc-shaped plate 23 is fixedly installed at the top of the arc-shaped groove 11. A liquid inlet pipe 5 is fixedly installed on the side of the fixed seat 1. A connection box 24 is fixedly installed inside the support seat 2. An opening 25 is formed in the connection box 24. A sealing block 26 is fixed on the inner wall of the opening 25. The sealing block 26 is movably installed on the side of the cold water pipe 9. Drain pipes 27 and 28 are respectively fixedly installed at the bottom of the support seat 2. One end of the drain pipe 27 is fixed on the connection box 24. The liquid inside the flat tube 10 and the liquid in the cold water pipe 9 are separated and discharged through the connection box 24.

[0023] When the device is in use, the water inlet pipe 4 and the liquid inlet pipe 5 are connected to external pipelines. The high-temperature liquid entering through the liquid inlet pipe 5 enters the inside of the fixed seat 1. The high-temperature liquid inside the fixed seat 1 enters the inside of the cavity 22 through the opening 16 under extrusion. The high-temperature liquid flows inside the cavity 22. At the same time, cold water enters through the water inlet pipe 4. The cold water enters the shunt box 18. The shunt box 18 sends the cold water into the inside of the cold water pipe 9 through the shunt pipe 19 and the connection hole 21. The cold water pipes 9 are distributed on the side of the flat tube 10. The flat tube 10 is initially heated by the cold water pipes 9. When the liquid inside the flat tube 10 flows, the width of the cavity 22 required by the arc-shaped plate 23 causes the liquid to slow down at the arc-shaped plate 23. The high-temperature liquid transfers the high temperature to the fin plate 12 through the arc-shaped plate 23. The fin plate 12 and the arc-shaped plate 23 cooperate to increase the heat absorption area. After the fin plate 12 absorbs heat, the high temperature on the fin plate 12 is quickly removed by the external air flow. Later, when the fin plate 12 is damaged by collision or corrosion, the limit bolt 15 is removed from the internal thread hole 14. The fin plate 12 loses the extrusion force and slides and is removed inside the fixed column 13 and the arc-shaped groove 11. When the fin plate 12 is removed, the flat tube 10 also loses the limit. Later, after the fixed seat 1 and the support seat 2 are opened, the flat tube 10 and the cold water pipe 9 can be horizontally drawn out for replacement. After the fin plate 12 is removed, a new fin plate 12 is installed on the arc-shaped groove 11 and the fixed column 13. The arc-shaped groove 11 limits the fin plate 12, and the fixed column 13 supports the fin plate 12. The high-temperature liquid later enters the inside of the connection box 24 and is discharged through the cooperation of the drain pipe 27. The water inside the cold water pipe 9 is discharged outward in a circulating manner through the drain pipe 28.
