Description

Technical Field

[0001] This invention belongs to the field of gas condensation technology, specifically relating to a flexible condenser with a finned structure and a method thereof. Background Technology

[0002] In numerous industrial and technological fields, the efficiency and stability of the condensation process are crucial. For example, in distillation, condensation efficiency directly affects product purity and production efficiency; in the nuclear industry, the large amount of heat generated by equipment operation requires a highly efficient condensation system to ensure safety and stability. Furthermore, existing traditional condensers face problems such as installation difficulties, space constraints, poor thermal stability, and poor environmental adaptability. Rigid materials lead to inconvenient installation, and they are prone to thermal expansion and corrosion in high-temperature or harsh environments. Therefore, solving the problems of inefficient condensation and inconvenient installation is particularly important. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a flexible condenser with a finned structure and a method thereof. This high-efficiency condensation device can be applied to various fields such as distillation and nuclear industry, and is convenient to install, use, and improve condensation efficiency.

[0004] The specific technical solution adopted in this invention is as follows:

[0005] In a first aspect, the present invention provides a flexible condenser with a finned structure, comprising a condenser plate and a condenser body, wherein the condenser plate is installed on the top of the open condenser body and the two together form a sealed condenser chamber;

[0006] The condensing chamber has a steam inlet on the left, a steam outlet on the right, and a liquid outlet at the bottom. The condensing plate has a refrigerant inlet on the left and a refrigerant outlet on the right, and has several refrigerant channels inside. The two ends of the refrigerant channels are connected to the refrigerant inlet and the refrigerant outlet, respectively. The bottom of the condensing plate has several raised fins. The fins have a conical structure, with the tips of the bottom bent in the same direction, which can guide and disturb the liquid condensed during the heat exchange process.

[0007] Preferably, the refrigerant inlet is connected to the inlet end of the refrigerant channel through a liquid distribution structure, which enables the refrigerant to be evenly distributed to each refrigerant channel.

[0008] Preferably, the outlet end of the refrigerant channel is connected to the refrigerant outlet through a liquid collection structure, which allows the refrigerant after heat exchange in each refrigerant channel to be collected at the refrigerant outlet.

[0009] Preferably, the refrigerant channels are parallel to each other and are horizontal cylindrical channels.

[0010] Preferably, both the condenser plate and the condenser body are made of flexible materials.

[0011] Furthermore, the flexible material includes silicone.

[0012] Preferably, the fins are evenly distributed at the bottom of the condenser plate.

[0013] Secondly, the present invention provides a heat exchange method utilizing a flexible condenser with a finned structure as described in any one of the first aspects, as follows:

[0014] Steam to be heated enters the condensing chamber through the steam inlet, while refrigerant enters the refrigerant channels in the condensing plate through the refrigerant inlet. During the heat exchange between the steam and the refrigerant, condensate gradually forms at the bottom of the condensing plate. Due to the curved conical structure of the fins, the condensate flows along the fin surface in the curved direction under the guidance of gravity and the fins, reducing flow resistance and preventing the condensate from accumulating at the bottom of the condensing plate to form a liquid film. At the same time, the fins have a disturbing effect on the flow of the condensate, which enhances the heat exchange effect, thereby transferring heat from the steam to the refrigerant more efficiently and further improving the condensation efficiency. The condensate that falls after being guided by the fins is finally discharged from the condensing chamber through the liquid outlet. The refrigerant, after heat exchange, finally flows out of the condensing plate through the refrigerant outlet.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1) The condenser plate and condenser body of the present invention are made of flexible materials. By utilizing their easy deformation and bending characteristics, the installation convenience of the condenser is greatly improved, and it can adapt to various complex installation environments. In addition, the good thermal stability and other characteristics of flexible materials ensure the stable and reliable operation of the condenser under different working conditions and extend the service life of the condenser.

[0017] 2) By setting a special shaped fin structure at the bottom of the condenser plate, the flow of condensate can be accelerated and the accumulation of liquid film can be reduced, thereby reducing the resistance generated by convective heat transfer. In addition, the disturbance effect of the fins on the liquid flow can also enhance the heat exchange effect, thereby improving the condensation efficiency of steam. Compared with traditional condensation devices, it has a significant performance improvement and improves the condensation efficiency. Attached Figure Description

[0030] like Figure 1 and 7 As shown, this invention provides a flexible condenser with a finned structure, which mainly includes a condensing plate 3 and a condenser body 7. The condenser body 7 is hollow inside and open at the top; the condensing plate 3 is installed at the open top of the condenser body 7, and the condensing plate 3 and the condenser body 7 together form a sealed condensing chamber 9. The condenser body 7 is provided with a steam inlet 2, a steam outlet 6, a condensing chamber 9, and a liquid outlet 4. The condensing plate 3 includes a refrigerant inlet 1, a liquid distribution structure 31, a refrigerant flow channel 32, a liquid collection structure 34, fins 33, and a refrigerant outlet 5. The structure of each module will be described in detail below.

[0031] In the device of the present invention, such as Figure 1 As shown, the condensing chamber 9 has a steam inlet 2 on the left side, a steam outlet 6 on the right side, and a liquid outlet 4 at the bottom. The space enclosed by the condensing plate 3 and the condenser body 7 is the condensing chamber 9. The steam inlet 2 is the steam inlet, the steam outlet 6 is the steam outlet after heat exchange, and the liquid outlet 4, located below the condenser body 7, effectively removes the liquid produced during condensation.

[0032] It should be noted that steam inlet 2 and steam outlet 6 are not limited to Figure 1 The left and right sides shown can also be opened on the front and rear sides respectively, as long as the steam inlet 2 and steam outlet 6 are opened on different sides of the condensing chamber 9 (preferably opposite sides) to ensure sufficient heat exchange of steam in the condensing chamber 9.

[0033] In the device of the present invention, such as Figure 2 As shown, a refrigerant inlet 1 is located on the left side of the condenser plate 3, and a refrigerant outlet 5 is located on the right side. It should be noted that the refrigerant inlet 1 and refrigerant outlet 5 are not limited to... Figure 1 The left and right sides shown can also be opened on the front and rear sides, etc., as long as the refrigerant inlet 1 and refrigerant outlet 5 are opened on different sides of the condenser plate 3 (preferably on the same side as the steam inlet 2 and steam outlet 6), and the refrigerant can fully exchange heat with the steam during the flow of the condenser plate 3.

[0034] As a preferred embodiment of the present invention, such as Figure 4As shown, the refrigerant inlet 1 is connected to the inlet end of the refrigerant channel 32 via a liquid distribution structure 31, which allows the refrigerant to be evenly distributed to each refrigerant channel 32. The outlet end of the refrigerant channel 32 is connected to the refrigerant outlet 5 via a liquid collection structure 34, which allows the refrigerant after heat exchange in each refrigerant channel 32 to be collected at the refrigerant outlet 5. In actual use, the refrigerant is collected in the liquid collection structure 34 after heat exchange in the refrigerant channel 32, and then flows out through the refrigerant outlet 5. The vapor in the condensation chamber 9 is condensed and forms a flowable liquid film 36 under the guidance of the fins 33.

[0035] Specifically, the refrigerant inlet 1 is the inlet for the refrigerant, and the refrigerant outlet 5 is the outlet for the refrigerant after heat exchange. The refrigerant enters through the refrigerant inlet 1. The liquid distribution structure 31 serves to uniformly disperse the refrigerant within the multiple fluid channels 32, while the liquid collection structure 34 serves to converge the refrigerant from the multiple fluid channels 32. The internal structures of the liquid distribution structure 31 and the liquid collection structure 34 are not fully shown in detail. These structures have a relatively small impact on the core content of this invention and can utilize existing structural compositions that achieve the same effect. However, it is still necessary to ensure uniform flow distribution characteristics in each channel to maximize the efficiency of the fin structure. For example, both the liquid distribution structure 31 and the liquid collection structure 34 can be configured as rectangular parallelepiped-shaped grooves.

[0036] In the device of the present invention, such as Figure 3 As shown, the condenser plate 3 is hollow inside and has multiple refrigerant channels 32. The two ends of the refrigerant channels 32 are connected to the refrigerant inlet 1 and the refrigerant outlet 5, respectively. The bottom of the condenser plate 3 has multiple protruding fins 33, that is, the fins 33 are located above the condenser chamber 9.

[0037] As a preferred embodiment of the present invention, such as Figure 3 As shown, the refrigerant flow channel 32 can take various shapes, including but not limited to parallel cylindrical flow channels. The cross-sectional shape of the refrigerant flow channel 32 can be adjusted according to specific design requirements and actual applications to meet different condensation scenarios.

[0038] In the device of the present invention, such as Figure 5 As shown, the fin 33 has a conical structure with the bottom tip bent in the same direction, which can guide and disturb the liquid condensed during the heat exchange process.

[0039] In a preferred embodiment of the present invention, the fins 33 should be evenly distributed at the bottom of the condenser plate 3 in order to better achieve the functions of guiding and turbulence.

[0040] Figure 5The fin 33 shown is only a typical design of this embodiment. In fact, the fin structure can be adapted to the actual situation, as long as the core of its structural design is met: the fin 33 adopts a curved inverted cone shape and the tips face the same direction to achieve directional flow of the condensed liquid; at the same time, the arrangement of the fins 33 must ensure that it can fully accelerate the liquid flow, reduce the accumulation of liquid film 36, and thus reduce the resistance generated by convective heat transfer.

[0041] like Figure 3 As shown, fins 33 are arranged at the lower part of the condenser plate 3. Each fin 33 has a certain effective range. The reason for arranging the fins 33 at the lower part of the condenser plate 3 is as follows: When liquid is generated during the condensation process, such as... Figure 4 As shown, due to the special shape of the fins 33, the liquid flows along the surface of the fins 33 under the guidance of the fins 33. Under the influence of gravity and the guiding effect of the fins 33, the liquid flows rapidly to the lower right, thus preventing the liquid from accumulating on the condenser plate 3 to form a liquid film 36. When the liquid flows on the fins 33, due to the guiding effect of the fins 33, the liquid can be discharged from the condenser plate 3 more quickly, reducing flow resistance. At the same time, the disturbance effect of the fins 33 on the liquid flow can also enhance the heat exchange effect, thereby transferring heat from the steam to the refrigerant more efficiently, further improving the condensation efficiency.

[0042] It should be noted that the flow guiding and heat transfer enhancement effects of fins 33 will vary depending on the steam and refrigerant under different operating conditions, but all will promote the condensation process. Optimizing flow and heat transfer can enhance the condensation effect. The specific dimensions and spacing of fins 33 can be adjusted according to actual operating conditions. While ensuring the above functions are achieved, the number, shape (e.g., changing the angle of the inverted cone), and spacing of fins 33 can be appropriately varied. Figure 4 As shown, in this embodiment, all fins 33 are arranged facing the fluid outlet direction.

[0043] It should be noted that the condenser structure can be flexibly changed according to the condensation and heat dissipation requirements, which can adaptively regulate the liquid flow and heat dissipation efficiency.

[0044] In a preferred embodiment of the present invention, both the condenser plate 3 and the condenser body 7 should be made of flexible materials, including but not limited to silicone. Figure 6 , Figure 6This is a schematic diagram of a flexible condenser with a finned structure bent 180°. The properties of flexible materials have a significant impact on the performance of the condenser. This is because, during installation, flexible materials exhibit significant advantages due to their easy deformation and bending characteristics. In installation environments with limited space or irregular shapes, such as inside some complex industrial equipment, traditional rigid condensers may be difficult to install or require complex custom installation structures. However, the flexible condenser of this invention can adapt to different installation spaces and shapes by bending and deforming the condensing plate 3 and the condenser body 7. For example, inside some confined electronic devices, the flexible condenser of this invention can be bent and deformed according to the internal space of the equipment, making installation more convenient, improving installation flexibility and convenience, and reducing installation space and time costs.

[0045] Furthermore, flexible materials possess excellent thermal stability, ensuring sufficient reliability of the condenser under various temperature conditions. For example, in industrial production processes, significant temperature fluctuations may occur, such as in the tail gas treatment of high-temperature reactors, where the condenser needs to process and cool the high-temperature tail gas. Special silicone materials can maintain structural and performance stability in such temperature-changing environments, without deformation, cracking, or performance degradation due to temperature changes. This ensures the continuity and efficiency of the entire condensation process, improving system reliability and service life. Selecting the most suitable flexible material based on actual operating conditions ensures that the condenser performs optimally in various application scenarios.

[0046] Utilizing the aforementioned flexible condenser with finned structure, this invention also provides a heat exchange method, which is as follows:

[0047] The steam to be heated enters the condensing chamber 9 through steam inlet 2, while the refrigerant enters the refrigerant channels 32 in the condensing plate 3 through refrigerant inlet 1. During the heat exchange process between the steam and the refrigerant, condensate gradually forms at the bottom of the condensing plate 3. Figure 4 As shown, due to the curved conical structure of the fins 33, the condensate flows along the curved direction of the fin surface under the guidance of gravity and the fins 33, reducing flow resistance and preventing the condensate from accumulating at the bottom of the condenser plate 3 to form a liquid film 36. Simultaneously, the fins 33 have a turbulent effect on the flow of the condensate, enhancing heat exchange and allowing heat to be transferred more efficiently from the steam to the refrigerant, further improving condensation efficiency. The condensate, after being guided by the fins 33, eventually exits the condenser chamber 9 through the liquid outlet 4. The refrigerant, after heat exchange, eventually flows out of the condenser plate 3 through the refrigerant outlet 5.

[0048] The condenser of this invention uses a flexible material (such as silicone), which has good thermal stability, is easily deformable and bendable, and is easy to install. Some special silicone materials also offer advantages such as high thermal conductivity and high tensile strength, making them suitable for various condensation structure conditions. During the condensation process, when liquid liquefies near the condenser plate, the fins not only accelerate the liquid flow and act as a directional guide, reducing the accumulation of the liquid film 36 and thus reducing the resistance generated by convective heat transfer, but also enhance the heat exchange effect through disturbance, thereby improving the efficiency of steam condensation. The condenser of this invention features convenient installation and good thermal stability, significantly improving the steam collection efficiency per unit volume of condenser.

[0049] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the invention. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention. Therefore, all technical solutions obtained through equivalent substitution or transformation fall within the protection scope of the present invention.
