Description

Technical Field

[0001] This application relates to the field of heat exchange technology, and in particular to a condensation component, condenser, and condensation equipment. Background Technology

[0002] Condensation units are core equipment in chemical, light industry, and other fields for achieving gas-liquid conversion. The condenser is responsible for condensing steam into a liquid state. Traditional condensers often employ a heat dissipation structure combining serpentine heat exchange tubes and fins. Steam releases heat inside the tubes, and the heat is transferred through the tube walls to the fins, where it is carried away by air convection. This method is technologically mature and simple in construction.

[0003] However, serpentine heat exchange tubes typically have thick walls, leading to significant drawbacks. First, the thicker walls increase thermal resistance, hindering heat transfer from the inner side of the tube to the finned side and limiting overall heat dissipation efficiency. Second, the thick walls significantly increase the weight of the tubes themselves, and to compensate for insufficient heat exchange, denser fins are often required, further increasing the weight of the condenser. This results in a high overall equipment weight, increasing material burden and negatively impacting lightweight design, installation, and maintenance. Summary of the Invention

[0004] Therefore, it is necessary to provide a condensation component, condenser, and condensation equipment to address the above problems.

[0005] This application provides a condensation assembly, comprising a support and a condenser tube assembly disposed on the support. The condenser tube assembly includes a heat exchange tube bank and a connecting pipe. Multiple heat exchange tube banks are stacked and arranged, each heat exchange tube bank including a first distribution pipe, a second distribution pipe, and multiple heat exchange tubes arranged side-by-side. One end of each heat exchange tube in a heat exchange tube bank is connected to the first distribution pipe, and the other end is connected to the second distribution pipe. The connecting pipe connects the first distribution pipe of one adjacent heat exchange tube bank to the second distribution pipe of another.

[0006] In one embodiment, at least two of the connecting pipes are connected to two adjacent heat exchanger tube banks, and the at least two connecting pipes are spaced apart.

[0007] In one embodiment, multiple connecting pipes on the same layer are spaced apart along the length direction of the connected second distribution pipe; in the length direction of the second distribution pipe, the shortest length from the edge of each connecting pipe on the same layer to the end of the second distribution pipe is L1, and the distance between adjacent connecting pipes on the same layer is L2, where 1.5L1≤L2≤2.5L1.

[0008] In one embodiment, the heat exchange tube is configured to have a uniform wall thickness in at least a portion of its area, the wall thickness of which is between 0.15 mm and 0.45 mm.

[0009] In one embodiment, the first distribution pipe and / or the second distribution pipe are configured to have a uniform wall thickness in at least a portion of the area, the thickness of the first distribution pipe and / or the second distribution pipe being between 0.55 mm and 0.85 mm.

[0010] In one embodiment, the number of heat exchange tube rows is 2 to 7.

[0011] In one embodiment, the number of heat exchange tubes included in a heat exchange tube bank is between 3 and 20.

[0012] In one embodiment, the number of the connecting pipes in the same layer is between 1 and 5.

[0013] In one embodiment, the inner circumferential surface of at least one of the heat exchange tube, the first distribution tube, the second distribution tube, and the connecting tube is configured with a smooth transition.

[0014] In one embodiment, the support is hollowed out, the first distribution pipe and the second distribution pipe are fixedly connected to the support, and at least part of the heat exchange tubes are suspended inside the support.

[0015] In one embodiment, multiple layers of heat exchange tubes are stacked in a first direction. The support has a heat exchange space with a first opening and a second opening at both ends in the first direction, allowing airflow to flow between the first opening and the second opening along the first direction. All heat exchange tubes are disposed within the heat exchange space, and the projection of the heat exchange tubes along the first direction is at least partially located within the first opening and the second opening.

[0016] In one embodiment, the condensation assembly further includes a support tube, which is hollow and connected between adjacent heat exchange tube rows. The connecting tube between two adjacent heat exchange tube rows and the support tube are located on opposite sides of the heat exchange tube rows, respectively.

[0017] In one embodiment, the condensation assembly further includes fins, with at least a portion of the heat exchange tube having the fins on its outer periphery, the heat exchange tube being configured to engage with the fins by tube expansion.

[0018] A second aspect of this application also provides a condenser, the condenser including an airflow generator and a condensation assembly as described above, the airflow generator being disposed on the bracket for outputting airflow to the condensation assembly.

[0019] In one embodiment, a plurality of the airflow generators are disposed on one side of the support and facing the condenser tube assembly in the stacking direction of the heat exchange tube array, and the plurality of the airflow generators are arranged in an array.

[0020] In one embodiment, the airflow generator is detachably connected to the bracket, and the detachment of the airflow generator from the bracket exposes the condenser tube assembly to the outside.

[0021] A third aspect of this application also provides a condensation device, the condensation device comprising a condensable medium generator, a collector, and a condenser as described above, wherein the condensable medium generator is used to supply the condensable medium to the condenser, and the collector is used to collect the condensed material after condensation treatment by the condenser.

[0022] In the aforementioned condensation assembly, each heat exchanger tube in a heat exchanger tube bank has one end connected to a first distribution pipe and the other end connected to a second distribution pipe. This ensures that both the medium input to and output from the heat exchanger tubes pass through the distribution pipes. Consequently, the medium within the multiple heat exchanger tubes can mix and redistribute within the first and second distribution pipes, improving the uniformity of medium temperature and pressure, enhancing the uniformity of condensation, and ensuring heat dissipation efficiency. Furthermore, the connecting pipe connects the first distribution pipe of one adjacent heat exchanger tube bank to the second distribution pipe of another, allowing multi-layered heat exchanger tube banks to be connected in series to form a single unit. This enables the medium to flow along an approximately S-shaped path between the heat exchanger tube banks. Compared to the integrated serpentine bend pipes in conventional technology, the connecting pipe in this application serves as an intermediate connecting element between adjacent heat exchanger tube banks, eliminating the need for bend pipes to achieve interconnection between the different layers of heat exchanger tube banks. Since the condenser tube assembly does not require bends, the heat exchange tubes, connecting tubes, and distribution tubes included in the condenser tube assembly can have thinner dimensions, thereby improving heat dissipation efficiency and reducing the overall structural weight, overall structural size, and material costs, achieving the goals of saving space, reducing costs, and lightweighting.

Detailed Implementation

[0036] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0037] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0038] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0039] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0040] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0041] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0042] The core component of a traditional condenser is the condenser tube, through which a vapor medium flows. The vapor medium dissipates heat through the tube wall, cooling to a liquid state. In traditional technology, to achieve sufficient length within a limited space, the condenser tube is typically constructed in a serpentine shape. This serpentine shape is usually achieved by bending straight tubes, which imposes a minimum thickness requirement. Understandably, if the condenser tube is too thin, it is prone to breakage or damage during bending, making it difficult to achieve the desired shape. Furthermore, the thickness of the serpentine condenser tube not only limits heat dissipation efficiency but also results in an excessively large and heavy overall size and weight of the condenser, restricting its usability in certain environments.

[0043] To address the aforementioned problems, this application provides a condensing assembly. The following detailed description, in conjunction with the accompanying drawings and specific embodiments, describes the condensing assembly, condenser, and condensing equipment provided in various embodiments of this application.

[0044] See Figure 1 and Figure 2 , Figure 1 An isometric schematic diagram of a condenser provided in one embodiment of this application is shown. Figure 2 for Figure 1The diagram shows an exploded view of the condenser. One embodiment of this application provides a condenser 30, which is used to condense a medium to be condensed, so that the vapor-state medium is condensed into a liquid substance. For ease of explanation, the vapor-state medium to be condensed and the medium to be condensed during the condensation process are referred to as the medium, and the liquid substance after condensation is referred to as the substance.

[0045] In one embodiment, the condenser 30 can be configured as an air-cooled condenser. The condenser 30 includes a condensation assembly 31 and an airflow generator 32. The condensation assembly 31 is used to contain the medium and provide a heat exchange environment for the condensation process of the medium. The airflow generator 32 is used to output airflow to the condensation assembly 31 to remove heat from the condensation assembly 31 through air convection, thereby achieving the purpose of condensation.

[0046] Of course, in other embodiments, the condenser 30 can be configured as a water-cooled condenser. In this case, the condenser 30 may include a liquid flow generator and a condensation assembly 31, the liquid flow generator being used to provide heat-absorbing fluid to the condensation assembly 31. For ease of explanation, the following description uses an example of the condenser 30 being configured as an air-cooled condenser.

[0047] Please see Figure 2 and Figure 3 The condensing assembly 31 provided in one embodiment of this application includes a support 100 and a condenser tube assembly 200. The condenser tube assembly 200 is disposed on the support 100, and the airflow generator 32 may also be disposed on the support 100. The condenser tube assembly 200 is used to contain the medium and provide a heat exchange environment for the condensation process of the medium.

[0048] The condenser tube assembly 200 includes heat exchange tube banks 201 and connecting pipes 240. Multiple heat exchange tube banks 201 are stacked and arranged, and the connecting pipes 240 connect adjacent heat exchange tube banks 201. Each heat exchange tube bank 201 includes a first distribution pipe 210, a second distribution pipe 220, and multiple heat exchange tubes 230 arranged side-by-side. One end of each heat exchange tube 230 in a heat exchange tube bank 201 is connected to the first distribution pipe 210, and the other end is connected to the second distribution pipe 220. The connecting pipe 240 connects the first distribution pipe 210 of one adjacent heat exchange tube bank 201 to the second distribution pipe 220 of another. For ease of explanation, the first distribution pipe 210 and the second distribution pipe 220 will be collectively referred to as distribution pipes below.

[0049] In the aforementioned condensation assembly 31, one end of each of the multiple heat exchange tubes 230 in a heat exchange tube bank 201 is connected to a first distribution pipe 210, and the other end is connected to a second distribution pipe 220. This ensures that both the medium input to and output from the multiple heat exchange tubes 230 will pass through the distribution pipe (i.e., the first distribution pipe 210 or the second distribution pipe 220). Specifically, for a heat exchange tube bank 201, one end of each of the multiple heat exchange tubes 230 is connected in parallel to the first distribution pipe 210; the other end of each of the multiple heat exchange tubes 230 is connected in parallel to the second distribution pipe 220. Therefore, the medium within the multiple heat exchange tubes 230 can mix and redistribute within the first distribution pipe 210 and the second distribution pipe 220, improving the uniformity of medium temperature and pressure, enhancing the uniformity of the condensation effect, and ensuring heat dissipation efficiency. It is understood that the heat dissipation efficiency of air convection is related to the temperature difference between the air and the medium; the greater the temperature difference, the faster the heat dissipation efficiency, and vice versa. This application, by setting up a first distribution pipe 210 and a second distribution pipe 220, enables the medium in multiple heat exchange tubes 230 to be collected and redistributed, thereby improving the uniformity of the medium temperature and giving the medium a higher overall heat dissipation efficiency.

[0050] Furthermore, the connecting pipe 240 connects the first distribution pipe 210 of one adjacent heat exchanger tube bank 201 to the second distribution pipe 220 of the other, thus allowing the multi-layered heat exchanger tube banks 201 to be connected in series to form a whole, enabling the medium to flow between the heat exchanger tube banks 201 along an approximately S-shaped path. Compared to the integrated serpentine bend pipe in conventional technology, the connecting pipe 240 in this application serves as an intermediate connecting element between adjacent heat exchanger tube banks 201, so that the heat exchanger tube banks 201 do not need to rely on bend pipes to achieve interconnection. Since the condenser tube assembly 200 does not need to be bend pipes, the heat exchanger tubes 230, connecting pipe 240, and distribution pipes included in the condenser tube assembly 200 do not need to be bent, thus allowing for a thinner thickness. This piping design, compared to the traditional integrated serpentine piping design, can improve heat dissipation efficiency and reduce the overall structural weight, overall structural size, and material cost, achieving the goals of saving space, cost, and lightweighting.

[0051] It is understandable that there is a gap between adjacent heat exchanger tube banks 201 to facilitate airflow and ensure adequate heat dissipation. Similarly, there is a gap between adjacent heat exchanger tubes 230 to facilitate airflow and ensure effective heat dissipation.

[0052] In one embodiment, the first distribution pipe 210 of one heat exchanger tube bank 201 is used to connect the medium to be condensed, and the second distribution pipe 220 of the other heat exchanger tube bank 201 is used to output the condensed substance, so that the medium can flow continuously within the condensation assembly 31.

[0053] For ease of explanation, each embodiment will be described using the example of a first distribution pipe 210 used to input the medium into the heat exchange tubes 230 of its respective heat exchange tube bank 201, and a second distribution pipe 220 used to output the medium from the heat exchange tubes 230 of its respective heat exchange tube bank 201 to the outside. That is, the first distribution pipe 210 of one heat exchange tube bank 201 is used to connect to the medium provided by the condensable medium generator 20 (described below), while the second distribution pipe 220 of the other heat exchange tube bank 201 outputs the substance to the collector 40 (described below).

[0054] Please see Figure 3 In one embodiment, the multi-layer heat exchanger tube banks 201 can be arranged in parallel. Of course, in some embodiments, the multi-layer heat exchanger tube banks 201 can also be configured to be inclined towards each other. As one example, the multi-layer heat exchanger tube banks 201 are stacked in a first direction S1.

[0055] Furthermore, the heat exchange tubes 230 included in the heat exchange tube bank 201 extend along the second direction S2 and are arranged side by side on the third direction S3. The second direction S2 intersects the third direction S3. Even further, the second direction S2 may be perpendicular to the third direction S3. Still further, the first direction S1, the second direction S2, and the third direction S3 may be arranged perpendicularly to each other in pairs.

[0056] In one embodiment, the first distribution pipe 210 and the second distribution pipe 220 may extend along the third direction S3 to communicate with each heat exchange pipe 230.

[0057] Please see Figure 3 In one embodiment, the first distribution pipe 210 of the heat exchange tube bank 201 located at the top in the first direction S1 is used to receive the medium, and the second distribution pipe 220 of the heat exchange tube bank 201 located at the bottom in the first direction S1 is used to discharge the substance. Thus, gravity can be used to improve the smoothness of the medium's flow within the condenser tube assembly 200.

[0058] Please see Figure 3 In one embodiment, the projections of the multilayer heat exchange tube array 201 along the first direction S1 at least partially overlap.

[0059] In one embodiment, the number of heat exchange tubes 230 included in each heat exchange tube bank 201 can be the same. Of course, the number of multiple heat exchange tube banks 201 can also vary depending on actual needs, and the embodiments of this application do not limit this.

[0060] Please see Figure 3 Combined Figure 1 and Figure 2In one embodiment, the first distribution pipe 210 and the second distribution pipe 220 are fixedly connected to the bracket 100. That is, the first distribution pipe 210 and the second distribution pipe 220 not only serve the functions of media integration and redistribution, but also serve the function of connection and installation. The bracket 100 is hollowed out, and at least part of the heat exchange tube 230 is suspended in the bracket 100 to reduce the possible obstruction of the heat exchange tube 230, so that the airflow generated by the airflow generator 32 can fully act on the heat exchange tube 230 and improve the heat dissipation effect.

[0061] Please see Figure 4 Combined Figure 1 and Figure 2 In one embodiment, the support 100 has a heat exchange space 101, within which all heat exchange tubes 230 are disposed, allowing for suspended placement and sufficient contact with air for heat exchange. The heat exchange space 101 has a first opening 103 and a second opening 104 at its two ends along the first direction S1, allowing airflow to flow between the first opening 103 and the second opening 104 along the first direction S1. Furthermore, the projection of the heat exchange tubes 230 along the first direction S1 is at least partially located within the first opening 103 and the second opening 104. Thus, the airflow flowing within the heat exchange space 101 can directly and effectively act on the heat exchange tubes 230, improving the heat exchange effect.

[0062] Please see Figure 2 The airflow generator 32 is disposed on the side of the bracket 100 where the first opening 103 is located in the first direction S1, so as to provide heat exchange airflow into the heat exchange space 101. At this time, the first opening 103 can be used as an airflow inlet and the second opening 104 as an airflow outlet.

[0063] Please see Figure 4 Combined Figure 1 In one embodiment, the support 100 has a receiving groove 102, the projection of which along the first direction S1 does not overlap with the first opening 103 and the second opening 104. The connecting pipe 240 is at least partially disposed within the receiving groove 102 to avoid obstructing airflow.

[0064] As one example, when the condenser 30 is in normal condensation operation, the first direction S1 can be vertical, the first opening 103 is opened at the top of the support 100 in the first direction S1, and the second direction S2 is opened at the bottom of the support 100 in the first direction S1. The receiving groove 102 is opened on the side of the support 100 perpendicular to the first direction S1.

[0065] Please see Figure 3In one embodiment, the support 100 includes a top frame 110, a bottom frame 120, and a column 130. The top frame 110 and the bottom frame 120 are spaced apart in a first direction S1, and the column 130 extends along the first direction S1 and connects to the top frame 110 and the bottom frame 120. The heat exchange space 101 may be located between the top frame 110 and the bottom frame 120. The top frame 110 may enclose a first opening 103, and the bottom frame 120 may enclose a second opening 104. Further, the side frames of the top frame 110, the side frames of the bottom frame 120, and the column 130 enclose a receiving groove 102.

[0066] In one embodiment, the side frames of the top frame 110 and / or the bottom frame 120 may be constructed as hollow rectangular tubes to further achieve lightweighting. The column 130 may be constructed as a hollow rectangular tube to achieve a lightweight design.

[0067] Please see Figure 3 In one embodiment, the column 130 protrudes from the bottom frame 120 in the first direction S1 away from the top frame 110, so that there is a certain gap between the second opening 104 and the arrangement plane of the condenser 30, reducing the risk of the second opening 104 being blocked.

[0068] Please see Figure 2 Combined Figure 1 In one embodiment, multiple airflow generators 32 are arranged in an array. The multiple airflow generators 32 are positioned on one side of the support 100 and facing the condenser tube assembly 200 in the stacking direction of the heat exchange tube array 201 (i.e., the first direction S1) to collectively provide airflow to the heat exchange tubes 230. It is understood that, for the same output airflow, the weight of multiple small airflow generators 32 is generally less than that of a single airflow generator 32. Therefore, this arrangement further enables the lightweighting of the condenser 30.

[0069] Furthermore, in the air-cooled condenser 30, the airflow generator 32 is typically configured as a fan. For example, the airflow at the central shaft of the fan is usually relatively small. Therefore, compared to a single airflow generator 32, this embodiment configures multiple airflow generators 32 arranged in an array, allowing areas with smaller airflow to be divided into multiple regions, improving the uniformity of airflow distribution and enhancing heat dissipation. Moreover, the parallel arrangement of multiple airflow generators 32 can achieve a larger output airflow, meeting the requirements for condensing the gas and liquid in the industrial-grade high-power condensable medium generator 20.

[0070] In one embodiment, the output of the airflow generator 32 can also be configured to be adjustable. For example, the power adapter of the airflow generator 32 can be adjusted by a knob to control the rotation speed of the airflow generator 32, thereby adjusting the airflow of the airflow generator 32 to achieve a predetermined liquid outlet temperature under different ambient temperatures.

[0071] Please see Figure 2 In one embodiment, the airflow generator 32 is detachably connected to the bracket 100. After the airflow generator 32 is detached from the bracket 100, the condenser tube assembly 200 is exposed to the outside so that the condenser tube assembly 200 can be inspected and cleaned.

[0072] As one example, the airflow generator 32 can be detachably connected to the bracket 100 via detachable connectors such as bolts.

[0073] Please continue reading. Figure 2 In one embodiment, the condenser assembly 31 further includes a mounting box 300 disposed on the bracket 100. The mounting box 300 has a mounting port 310 through which the airflow generator 32 can be detachably inserted into the mounting box 300 for fixation relative to the bracket 100. The airflow generator 32 is installed using the detachable insertion method provided in this embodiment, which facilitates easy installation and removal, and makes it convenient for maintenance and cleaning of the condenser tube assembly 200 and fins 260.

[0074] Furthermore, the mounting box 300 can be configured with a perforated design to facilitate air intake for the airflow generator 32 and to facilitate heat dissipation for the condenser coil assembly 200.

[0075] In one embodiment, the airflow generator 32 has a dust filter 32a, which is located on the air inlet side of the airflow generator 32 to allow air to enter the airflow generator 32. The dust filter 32a can filter dust, lint, and other debris from the external environment and prevent a person from being accidentally scratched by the airflow generator 32 if they accidentally put their hands into the mounting box 300. Furthermore, the gap of the dust filter 32a can be less than 7 mm. Even further, the gap of the dust filter 32a can be configured to be less than 4 mm.

[0076] In one embodiment, the number of airflow generators 32 can be from one to seven, and the number of airflow generators 32 can be increased or decreased according to actual needs. For example, the number of airflow generators 32 can be one, two, three, four, five, six, and seven, etc. As one example, multiple airflow generators 32 can be arranged in a rectangular array in the second direction S2 and the third direction S3.

[0077] Please see Figure 5 In one embodiment, the condensing assembly 31 further includes fins 260, with at least a portion of the heat exchange tubes 230 having fins 260 on their outer periphery. The fins 260 increase the heat exchange area of ​​the condensing assembly 31, thereby improving heat dissipation. Furthermore, considering the detachable nature of the airflow generator 32, lint, dust, and other debris adhering to the fins 260 can be cleaned by disassembling the airflow generator 32, ensuring that the condensing assembly 31 maintains good condensation performance even after prolonged use.

[0078] In one embodiment, the heat exchange tube 230 is configured to be joined to the fins 260 by tube expansion. It is understood that the heat exchange tube 230 provided in this application has a relatively thin thickness, and using conventional winding methods to install the fins 260 onto the heat exchange tube 230 can easily lead to damage to the heat exchange tube 230. This embodiment uses tube expansion to join the heat exchange tube 230 to the fins 260, which can reduce damage to the outer and inner walls of the heat exchange tube 230 during the joining process.

[0079] It is understandable that the aforementioned method of joining the heat exchange tube 230 and fins 260 using a winding method refers to spirally winding the strip-shaped fins 260 around the outer wall of the heat exchange tube 230 under tension to form continuous fins 260. Since the edges of the fin strips are sharp, the outer wall of the heat exchange tube 230 may be damaged during the dynamic winding process. The aforementioned method of joining the heat exchange tube 230 and fins 260 using a tube expansion method refers to first fitting the fins 260 onto the outside of the heat exchange tube 230, and then radially expanding the heat exchange tube 230 through mechanical or hydraulic means to form an interference fit with the fins 260 and secure them together. It should be noted that this is only an example illustrating the joining method of the fins 260 and the heat exchange tube 230, and is not a limitation on the joining method.

[0080] In one embodiment, the connecting pipe 240 can be connected to the first distribution pipe 210 and the second distribution pipe 220 by welding.

[0081] In one embodiment, using a single connecting pipe 240 to connect adjacent heat exchanger tube banks 201 may result in heat exchanger tubes 230 closer to the connecting pipe 240 receiving more flow, while heat exchanger tubes 230 at the relative edges receive relatively less flow. Therefore, please refer to... Figure 6 Combined Figure 3 In this embodiment, at least two connecting pipes 240 can be configured to connect two adjacent heat exchanger tube rows 201, and at least two connecting pipes 240 are spaced apart, so that the flow rate input to each heat exchanger tube 230 is approximately the same, thereby improving the uniformity of flow distribution.

[0082] For ease of explanation, in each embodiment, the multiple connecting pipes 240 that are connected to two adjacent heat exchanger tube banks 201 are referred to as connecting pipes 240 of the same layer.

[0083] Please see Figure 7 In one embodiment, multiple connecting pipes 240 of the same layer are distributed at intervals along the length direction (i.e., third direction S3) of the connected second distribution pipe 220, so that multiple heat exchange pipes 230 arranged side by side in the length direction of the second distribution pipe 220 can obtain media with approximately the same flow rate.

[0084] Please see Figure 6 and Figure 7In one embodiment, along the length of the second distribution pipe 220, the shortest length from the edge of each connecting pipe 240 in the same layer to the end of the second distribution pipe 220 is L1, and the spacing between adjacent connecting pipes 240 in the same layer is L2, where 1.5L1≤L2≤2.5L1. It is understood that the connecting pipe 240 can transport the medium to the heat exchange pipes 230 located on both sides of the second distribution pipe 220. In this embodiment, the spacing setting described above ensures that the number of heat exchange pipes 230 within a certain range of each connecting pipe 240 is approximately the same, resulting in approximately the same medium flow rate received by each heat exchange pipe 230. By improving the flow uniformity within each heat exchange pipe 230, the overall heat exchange effect is improved.

[0085] As one example, L2 can be 1.5L1, 2L2, or 2.5L1, etc.

[0086] In one embodiment, the heat exchange tube 230 is configured with a uniform wall thickness in at least a portion of its area, the wall thickness of which is between 0.15 mm and 0.45 mm, to balance the heat exchange efficiency and structural strength of the heat exchange tube 230. This configuration ensures sufficient structural strength for the heat exchange tube 230, reducing the risk of deformation or damage during transportation, storage, and use. As one example, the heat exchange tube 230 can be made of stainless steel. As another example, the thickness of the heat exchange tube 230 can be 0.15 mm, 0.2 mm, 0.25 mm, 0.3 mm, 0.35 mm, 0.4 mm, and 0.45 mm, etc.

[0087] In one embodiment, the first distribution pipe 210 and / or the second distribution pipe 220 are configured with at least a portion of uniform wall thickness, the thickness of the first distribution pipe 210 and / or the second distribution pipe 220 being between 0.55 mm and 0.85 mm, to balance the heat exchange efficiency and structural strength of the distribution pipes. This configuration ensures sufficient structural strength for the distribution pipes, reducing the risk of deformation or damage during transport, storage, and use. As one example, the distribution pipes can be made of stainless steel. As another example, the thickness of the distribution pipes can be 0.55 mm, 0.6 mm, 0.65 mm, 0.7 mm, 0.75 mm, 0.8 mm, and 0.85 mm, etc. It is understood that the distribution pipes have a greater thickness than the heat exchange tubes 230 to ensure stable connection with the support 100 and to support each heat exchange tube 230 and the connecting pipe 240.

[0088] Please see Figure 3 Combined Figure 8In one embodiment, the number of heat exchanger tube rows 201 is 2 to 7, and the number of heat exchanger tube rows 201 can be configured according to the actual usage requirements of the condenser 30. When there is a high condensation demand, a relatively large number of heat exchanger tube rows 201 can be configured; conversely, a relatively small number of heat exchanger tube rows 201 can be configured. For example, the number of heat exchanger tube rows 201 can be 2, 3, 4, 5, 6, or 7.

[0089] Please see Figure 6 In one embodiment, the number of heat exchange tubes 230 included in a heat exchange tube bank 201 ranges from 3 to 20. Similarly, the number of heat exchange tubes 230 included in a heat exchange tube bank 201 can be configured according to the actual usage requirements of the condenser 30. When there is a high condensation demand, the number of heat exchange tubes 230 included in the heat exchange tube bank 201 can be relatively large; conversely, the number of heat exchange tubes 230 included in the heat exchange tube bank 201 can be relatively small. As one example, the number of heat exchange tubes 230 included in the heat exchange tube bank 201 can be 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, and 20, etc.

[0090] Please see Figure 6 In one embodiment, the number of connecting pipes 240 in the same layer is between one and five, to balance the requirements of flow uniformity and lightweight design. The number of support pipes 250 in the same layer can be one, two, three, four, or five, etc.

[0091] In one embodiment, the inner circumferential surface of at least one of the first distribution pipe 210, the second distribution pipe 220, the heat exchange pipe 230, and the connecting pipe 240 is configured with a smooth transition, without sharp edges or grooves, to reduce the risk of bacteria growth due to media remaining inside the respective pipe fittings. This configuration allows the condenser assembly 31 to be used in media condensation operations where hygiene is a certain requirement.

[0092] As one example, the inner circumferential surfaces of the first distribution pipe 210, the second distribution pipe 220, the heat exchange pipe 230, and the connecting pipe 240 can all be configured with a smooth transition.

[0093] In one embodiment, the first distribution pipe 210, the second distribution pipe 220, the heat exchange pipe 230, and the connecting pipe 240 can be configured as round pipes or elliptical pipes, etc.

[0094] Please see Figure 9 Combined Figure 3In one embodiment, the condensation assembly 31 further includes a support pipe 250, which connects adjacent heat exchange tube rows 201 to support two adjacent heat exchange tube rows 201. Furthermore, the connecting pipe 240 and the support pipe 250, located between two adjacent heat exchange tube rows 201, are respectively located on opposite sides of the heat exchange tube rows 201. It is understood that the connecting pipe 240, connecting two adjacent heat exchange tube rows 201, can also support the two adjacent heat exchange tube rows 201. Therefore, in this embodiment, the connecting pipe 240 and the support pipe 250 are configured to be located on opposite sides of the heat exchange tube rows 201, allowing the connecting pipe 240 and the support pipe 250 to cooperate with each other and improve the uniformity of the support effect.

[0095] In one embodiment, the support tube 250 is hollow to further achieve an overall lightweight design.

[0096] In one embodiment, the number of support tubes 250 in the same layer is between one and five, in order to balance the effectiveness of the support and the lightweight design requirements of the overall structure. The number of support tubes 250 in the same layer can be one, two, three, four, or five, etc.

[0097] In one embodiment, any one of the first distribution pipe 210, the second distribution pipe 220, the heat exchange pipe 230, the connecting pipe 240, and the support pipe 250 may be constructed as a straight pipe.

[0098] Please see Figure 10 In one embodiment, the condenser assembly 31 further includes an outer cover 500, which covers the support 100 and the condenser tube assembly 200 to reduce the risk of airflow leakage provided by the airflow generator 32, thereby concentrating the airflow onto the condenser tube assembly 200 and improving heat dissipation. Simultaneously, the outer cover 500 covering the support 100 and the condenser tube assembly 200 reduces interference from external debris or external temperature sources on the condensation heat exchange process.

[0099] As one example, the outer cover 500 can be configured with materials such as plastic, Oxford cloth, and canvas to achieve an overall lightweight design while keeping costs down.

[0100] Please see Figure 11 and Figure 12 An embodiment of this application also provides a condensation device 10. The condensation device 10 can be used for brewing, or for the production and processing of substances such as pure water, essential oils, and vegetable oil.

[0101] The condensation device 10 includes a condensable medium generator 20, a collector 40, and a condenser 30 as described in various embodiments. The condensable medium generator 20 is used to supply the condensable medium to the condenser 30, and the collector 40 is used to collect the condensed material after condensation treatment by the condenser 30.

[0102] The condensate generator 20 can be configured as various types of generators, and this application does not limit it.

[0103] See Figure 11 As one example, the condensate generator 20 can be configured as an electrically heated condensate generator.

[0104] See Figure 12 As one example, the condensate generator 20 can be configured to include an induction cooker and a distillation pot, wherein the substrate in the distillation pot is heated by the induction cooker, causing the substrate to evaporate and separate to obtain the condensate.

[0105] Furthermore, the condensate generator 20 can also be configured as a gas-fired steam generator, a coal gas-fired steam generator, or an electric ceramic stove-fired steam generator, etc.

[0106] In one embodiment, the condensing device 10 further includes an inlet pipe 50 and an outlet pipe 60. The inlet pipe 50 connects the condensable medium generator 20 and the condenser 30, and the outlet pipe 60 connects the condenser 30 and the collector 40. As one example, the inlet pipe 50 and the outlet pipe 60 can be configured as silicone hoses. In this embodiment, the condensable medium generator 20, the condenser 30, and the collector 40 included in the condensing device 10 are connected by the inlet pipe 50 and the outlet pipe 60, making the three independent of each other and allowing them to be disassembled for transportation or storage, making them easy and convenient to use.

[0107] Please see Figure 3 In one embodiment, the condensing assembly 31 further includes interface members 400, one interface member 400 for connecting the condensable medium generator 20 and the condenser 30, and another interface member 400 for connecting the condenser 30 and the collector 40. As one example, the interface member 400 may be made of stainless steel. The interface member 400 may be configured as a fish-mouth part or an elbow, etc. Further, the interface member 400 may be located in the condenser tube assembly 200.

[0108] It should be noted that the condenser 30 and the condensing device 10 including the condenser 30 provided in the embodiments of this application, including the condensing component 31 provided in the embodiments, have higher heat exchange efficiency. Therefore, under the same condensation requirements, the output power of the airflow generator 32 can be reduced to achieve energy saving. At the same time, due to the high heat exchange efficiency of the condensing component 31, the condenser 30 and the condensing device 10 provided in this application can be used to condense the high-temperature vapor-liquid output from the condensable medium generator 20 with a power of 5000W or more. Its heat dissipation effect is highly efficient and can be widely used in household, laboratory, and industrial distillation applications.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0110] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
