Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange equipment, and particularly relates to a finned heat exchanger. Background Art

[0002] The finned heat exchanger is a relatively commonly used heat exchange device, which is usually applied to the heat exchange of liquid or gas media. For the heating, cooling, and heat preservation of liquid or gas media, steam or waste hot water can be used for heating, and chilled water can be used for cooling.

[0003] In the process of pharmaceutical production, there is a large amount of waste heat that can be utilized, such as high-temperature cleaning water and steam condensate of equipment. Most of the waste heat is discarded because it cannot be directly utilized, resulting in waste of resources. Generally, the tube side of the conventional finned heat exchanger uses clean media for heat exchange, and it cannot stably utilize waste heat containing impurities such as high-temperature cleaning water for a long time, resulting in a single heat source and poor energy-saving effect. Summary of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a finned heat exchanger, aiming to solve the problem of poor energy-saving effect of the current finned heat exchanger in the prior art.

[0005] A finned heat exchanger proposed by an embodiment of the utility model includes a heat release component, an exchange pipeline communicating with the heat release component, a primary fin group sleeved on the outer surface of the exchange pipeline, and a secondary fin group sleeved on at least part of the heat release component;

[0006] The heat release component includes a liquid collecting tray arranged at the bottom for connecting the exchange pipeline, a plurality of flow dividing partitions arranged in a staggered manner on the inner wall of the liquid collecting tray, a heat absorption part embedded in the liquid collecting tray and located between at least two adjacent flow dividing partitions, and a heat release part extending from the heat absorption part towards the outside of the liquid collecting tray. The secondary fin is sleeved on the outer surface of the heat release part.

[0007] As described above, by introducing steam into the exchange pipeline, the surface of the exchange pipeline releases heat and cooperates with the primary fin group to transfer heat energy. After the steam releases heat through the exchange pipeline, it will form condensate and be introduced into the liquid collecting tray in the heat release component, so that the condensate contacts the heat absorption part in the liquid collecting tray. The residual heat energy in the condensate will also be fully absorbed by the heat absorption part and conducted to the heat release part, and the secondary fin group sleeved on the heat release part transfers the heat energy, so as to make full use of waste heat to achieve the effect of secondary utilization of condensate, and solve the problem of poor energy-saving effect of the current finned heat exchanger.

[0008] In addition, the finned heat exchanger proposed by an embodiment of the utility model may also have the following additional technical features:

[0009] Further, the exchange pipeline includes a first copper pipe, a plurality of U-shaped pipes with one end communicating with the first copper pipe, a second copper pipe communicating with the other ends of the plurality of U-shaped pipes, and a drain pipe extending outward along the bottom of the second copper pipe and communicating with the liquid collecting tray. A steam inlet is provided at the top of the first copper pipe.

[0010] Further, each of the U-shaped pipes is composed of four parallel straight pipes and three U-shaped joints. One U-shaped joint is provided on one side of the straight pipe close to the first copper pipe and the second copper pipe, and two U-shaped joints are provided on the side of the straight pipe away from the first copper pipe and the second copper pipe, so as to integrally connect the U-shaped pipes.

The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0026] Please refer to Figures 1 to 6 , which shows a finned heat exchanger in an embodiment of the present utility model, including a heat release component 1, an exchange pipeline 2 communicating with the heat release component 1, a primary fin group 3 sleeved on the outer surface of the exchange pipeline 2, and a secondary fin group 4 sleeved on at least part of the heat release component 1. The heat release component 1 includes a liquid collecting tray 11 provided at the bottom for communicating with the exchange pipeline 2, a plurality of flow dividing partitions 12 arranged in a staggered manner on the inner wall of the liquid collecting tray 11, a heat absorption part 13 embedded in the liquid collecting tray 11 and located between at least two adjacent flow dividing partitions 12, and a heat release part 14 extending outward from the heat absorption part 13 toward the outside of the liquid collecting tray 11. A secondary fin 4 is sleeved on the outer surface of the heat release part 14. Among them, after the steam passing through the exchange pipeline 2 condenses into water, it is introduced into the liquid collecting tray 11 communicated therewith, and after contacting the heat absorption part 13 in the liquid collecting tray 11, the heat energy is transferred along the heat absorption part 13 to the heat release part 14.

[0027] Further, the exchange pipeline 2 includes a first copper pipe 21, multiple U-shaped pipes 23 with one end communicating with the first copper pipe 21, a second copper pipe 24 communicating with the other ends of the multiple U-shaped pipes 23, and a drain pipe 25 extending outward from the bottom of the second copper pipe 24 and communicating with the liquid collecting tray 11. A steam inlet 22 is provided at the top of the first copper pipe 21. Each U-shaped pipe 23 is composed of four parallel straight pipes and three U-shaped joints. One U-shaped joint is provided on the side of the straight pipe close to the first copper pipe 21 and the second copper pipe 24, and two U-shaped joints are provided on the side of the straight pipe far from the first copper pipe 21 and the second copper pipe 24 to integrally connect the U-shaped pipe 23. The first fin group 3 is composed of multiple first fins 31 arranged in parallel. Multiple first connection holes 32 for accommodating the four straight pipes are provided on the first fins 31. The second fin group 4 is composed of multiple second fins 41 arranged in parallel. Multiple second connection holes 42 for accommodating the heat release part 14 are provided on the second fins 41. The first fins 31 are arranged horizontally in parallel along the X-axis, and the second fins 41 are arranged vertically in parallel along the Y-axis. The first fins 31 and the second fins 41 are arranged perpendicular to each other.

[0028] In specific implementation, first, the operator can dock the steam inlet 22 with an external steam conduit. In some alternative embodiments, an external thread or sleeve adapted to the external steam conduit can be provided at the steam inlet 22 to complete the connection between the steam inlet 22 and the external steam conduit. Then, the steam is introduced into the first copper pipe 21 through the external steam engine along the external steam conduit to the steam inlet 22. Then, the first copper pipe 21 diverts the steam into multiple U-shaped pipes 23 communicating therewith to provide heat energy. It should be noted that the U-shaped pipes 23 can be made of the same metal copper pipe as the first copper pipe 21. During the process, the heat energy is transferred through the first fin group 3 provided on the outer surface of the U-shaped pipes 23, and the heat release quality of the U-shaped pipes 23 is improved. After that, after heat release, the steam will be introduced into the second copper pipe 24 along the U-shaped pipes 23. During the process, the steam will also form condensate water and flow into the second copper pipe 24 after heat release. In some alternative embodiments of the present invention, to avoid the condensate water in the U-shaped pipes 23 from flowing back or not flowing smoothly, the second copper pipe 24 can be arranged at a lower horizontal position than the first copper pipe 21 to facilitate the condensate water formed in the U-shaped pipes 23 to flow towards the second copper pipe 24 on the lower side. Then, the condensate water can be introduced into the liquid collecting tray 11 along the drain pipe 25 at the bottom of the second copper pipe 24 and fill the liquid collecting tray 11 along the separation path of the separation partition 12. It should be noted that the flow rate of the water flow channel in the liquid collecting tray 11 can be restricted by the separation partition 12, so that the condensate water will fully contact the heat absorption part 13 between two adjacent separation partitions 12. The residual heat energy in the condensate water will also be fully absorbed by the heat absorption part 13 and conducted to the heat release part 14. Finally, the heat energy is transferred through the second fin group 4 sleeved on the heat release part 14 to achieve the effect of fully utilizing waste heat for secondary utilization of condensate water.

[0029] In addition, in some alternative embodiments of the present utility model, a plurality of through holes are further provided at the connection between the liquid collecting tray 11 and the drain pipe 25. Multiple external pipelines can be connected through the through holes to guide different waste heat heat sources into the liquid collecting tray 11, effectively avoiding frequent replacement of pipelines to switch heat sources, centralized recovery of waste heat, reduction of equipment investment. At the same time, the inner wall of the liquid collecting tray 11 can adopt a sealing plate sealing design to form an inner liner structure inside the liquid collecting tray 11, facilitating subsequent disassembly and cleaning.

[0030] In summary, by introducing steam into the exchange pipeline 2, heat is released from the surface of the exchange pipeline 2 and heat transfer of the heat energy is carried out in cooperation with the primary fin group 3. After the steam releases heat through the exchange pipeline 2, condensate is formed and introduced into the liquid collecting tray 11 in the heat release assembly 1, enabling the condensate to come into contact with the heat absorption part 13 in the liquid collecting tray 11. The residual heat energy in the condensate is also fully absorbed by the heat absorption part 13 and conducted to the heat release part 14, and the secondary fin group 4 sleeved on the heat release part 14 conducts heat transfer of the heat energy, so as to achieve the effect of secondary utilization of condensate by making full use of waste heat. The high-efficiency heat exchange device can utilize waste heat nearby, is suitable for the working specific environment of the pharmaceutical industry, realizes the nearby recovery and reuse of waste heat, is both economical and efficient, and conforms to the national environmental protection policy, having remarkable economic and social benefits, and solving the problem of poor energy-saving effect of the current fin heat exchanger.
