Description

Technical Field

[0001] This utility model relates to the field of heat exchange equipment technology, and in particular to a water distribution system. Background Technology

[0002] Traditional condenser water distribution systems typically use single-row pipes for direct water spraying or spray nozzles to distribute cooling water. However, these systems have several problems in practical applications: when cooling water flows onto the heat exchange tube banks, it easily splatters, and the water flow is insufficient and unevenly distributed. These problems result in extremely uneven distribution of cooling water on the condenser surface, leading to dry spots, scale formation, and the inability to form a continuous water film on the heat exchange tube bank surface. This significantly reduces the condenser's evaporative heat exchange efficiency and wastes water resources.

[0003] Furthermore, traditional water distribution devices typically only perform one water distribution cycle. To achieve a more uniform water distribution effect, the outlet holes are designed to be relatively small. While this can improve the uniformity of water distribution to some extent, it also makes the outlet holes more prone to clogging, increasing long-term maintenance costs and workload. Once the outlet holes become clogged, it not only affects the uniformity of water distribution but also further weakens the condenser's heat dissipation effect, reducing the overall efficiency of the equipment. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a water distribution system that can improve the evaporative heat exchange efficiency of the system.

[0005] A water distribution system according to a first aspect embodiment of the present invention includes:

[0006] The heat exchange tube bank has several guide vanes evenly distributed along the heat sink at its top.

[0007] A water distribution assembly is fixedly installed above the heat exchange tube bank. The water distribution assembly includes a first receiving cavity and a second receiving cavity, which extend along the straight pipe direction of the heat exchange tube bank. One end of the assembly is connected to a water supply pipe, and the other end is sealed with a plug. The second receiving cavity is connected to the first receiving cavity through water guide holes, which are evenly distributed at the bottom of the first receiving cavity. The side wall of the second receiving cavity abuts against the guide plate to form a water distribution channel.

[0008] The cooling water enters the first receiving cavity through the water supply pipe, then flows into the second receiving cavity through the water guide hole, and is guided by the guide plate to be evenly distributed on the surface of the heat exchange tube bank to form a continuous water film.

[0009] The water distribution system according to the embodiments of this utility model has at least the following beneficial effects: The water distribution components and heat exchange tubes of this water distribution system work together to significantly improve the uniformity of cooling water distribution and heat exchange efficiency. The guide vanes set on the top of the heat exchange tubes can effectively guide the cooling water flow, ensuring that the cooling water is evenly distributed on the surface of the heat exchange tubes and forms a continuous water film. This effectively avoids the dry spots and splashing phenomena common in traditional water distribution methods, thereby improving the evaporative heat exchange efficiency. The first and second receiving chambers of the water distribution components are connected through evenly distributed water guide holes. This design allows the cooling water to flow smoothly and evenly from the first receiving chamber into the second receiving chamber, and achieves a finer water flow distribution under the action of the guide vanes. This not only helps to form a more uniform water film coverage, but also reduces the problem of local overheating or overcooling caused by uneven water flow, further improving the overall performance and stability of the system. Since the cooling water can be directly and evenly distributed to the surface of the heat exchange tubes under the guidance of the guide vanes, this not only improves the heat exchange efficiency, but also reduces the waste of water resources.

[0010] According to some embodiments of this utility model, the volume of the first receiving cavity is V1, and the volume of the second receiving cavity is V2, satisfying V1:V2≥3. The larger first receiving cavity can effectively store and buffer the incoming cooling water, ensuring a stable and continuous water supply process, avoiding uneven water distribution caused by water flow fluctuations, and achieving precise distribution and uniform outflow of cooling water. Since the volume of the second receiving cavity is smaller, the water flow velocity inside it is relatively faster, which helps the cooling water to pass through the water distribution channel more efficiently and be guided by the guide vanes to the surface of the heat exchange tube bank, forming a more uniform water film distribution.

[0011] According to some embodiments of this utility model, the guide vanes are disposed on both sides of the top of the heat exchange tube bank, and the guide vanes on both sides are arranged in an opposing and staggered manner. This can avoid the problem of water flow being biased to one side that may be caused by unidirectional flow guidance, ensuring that the cooling water can cover the entire heat exchange surface, thereby improving heat exchange efficiency.

[0012] According to some embodiments of this utility model, the water guide holes are spaced apart along the extension direction of the first receiving cavity. By spaced the water guide holes along the extension direction of the first receiving cavity, it can be ensured that cooling water can flow evenly from the first receiving cavity into the second receiving cavity, avoiding the problem of excessively strong or weak water flow in local areas, and making the water flow into the second receiving cavity more stable and evenly distributed.

[0013] According to some embodiments of this invention, the fin tips of the heat exchange tube bank are oriented towards the water distribution assembly. This fin tip-oriented design allows for more effective guidance of cooling water flow along the fin surface. This directional design helps ensure that the cooling water disperses quickly and evenly upon contact with the heat exchange tube bank, forming a continuous water film covering the entire heat exchange surface, thereby improving heat exchange efficiency.

[0014] According to some embodiments of this utility model, the cross-section of the water distribution assembly is a streamlined structure, and the projection of the water distribution assembly toward the heat exchange tube bank completely covers the outer contour of the heat exchange tube bank. The streamlined structure design reduces the obstruction of the water distribution assembly to the airflow through the heat exchanger, allowing air to pass through the heat exchange tube bank more smoothly, reducing air turbulence and resistance caused by structural irregularities or protrusions, thereby improving air cooling efficiency.

[0015] According to some embodiments of this utility model, the water distribution assembly further includes at least one secondary water supply hole, which is located in the middle section of the length direction of the water distribution assembly and is connected to the first receiving cavity. This allows for the replenishment of water in the middle section, ensuring a more uniform distribution of cooling water along the entire length of the heat exchange tube bank.

[0016] According to some embodiments of this utility model, the guide vane is a mesh-like flow-guiding structure woven or stamped from metal wire. The mesh structure can effectively disperse the water flow, avoiding local impact and uneven distribution caused by excessive water flow at a single point, allowing the cooling water to more evenly cover the surface of the heat exchange tube bank, forming a continuous and stable water film.

[0017] According to some embodiments of this utility model, the guide strip is a flow guide bar made of flexible material. The flow guide bar made of flexible material can be finely adjusted according to the specific shape of the heat exchange tube bank surface to ensure a tight fit, which helps to guide the cooling water to be more evenly distributed on the heat exchange surface, forming a continuous and stable water film, effectively avoiding the uneven water flow problem that may be caused by traditional rigid guide strips.

[0018] According to some embodiments of this utility model, the guide vane is a wave-shaped flow-guiding structure formed by rolling the edge of the heat exchange tube bank. The wave-shaped flow-guiding structure can more effectively guide the cooling water to flow along a specific path. Compared with a planar guide vane, the wave-shaped design increases the length of the water flow path and the contact area, allowing the cooling water to be more evenly distributed on the surface of the heat exchange tube bank, forming a continuous and stable water film, effectively avoiding local dry spots or water accumulation.

[0019] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0031] Reference Figures 1 to 5 A water distribution system, comprising:

[0032] The heat exchange tube bank 110 has several guide vanes 120 evenly distributed along the heat sink at its top.

[0033] A water distribution assembly 100 is fixedly installed above the heat exchange tube bank 110. The water distribution assembly 100 includes a first receiving cavity 150 and a second receiving cavity 160, which extend along the straight pipe direction of the heat exchange tube bank 110. One end of the assembly is connected to a water supply pipe, and the other end is sealed with a plug. The second receiving cavity 160 is connected to the first receiving cavity 150 through water guide holes 170, which are evenly distributed at the bottom of the first receiving cavity 150. The side wall of the second receiving cavity 160 abuts against the guide plate 120 to form a water distribution channel.

[0034] The cooling water enters the first receiving cavity 150 through the water supply pipe, then flows into the second receiving cavity 160 through the water guide hole 170, and is guided by the guide plate 120 to be evenly distributed on the surface of the heat exchange tube bank 110 to form a continuous water film.

[0035] The water distribution system, consisting of a water distribution assembly 100 and a heat exchange tube bank 110, works in conjunction to significantly improve the uniformity of cooling water distribution and heat exchange efficiency. The guide vanes 120 located at the top of the heat exchange tube bank 110 effectively guide the cooling water flow, ensuring that the cooling water is evenly distributed on the surface of the heat exchange tube bank 110 and forms a continuous water film. This effectively avoids the dry spots and splashing phenomena common in traditional water distribution methods, thereby improving evaporative heat exchange efficiency. The first receiving cavity 150 and the second receiving cavity 160 of the water distribution assembly 100 are connected by evenly distributed water guide holes 170. This design allows cooling water to flow smoothly and evenly from the first receiving cavity 150 into the second receiving cavity 160, and achieves finer water flow distribution under the action of the guide vanes 120. This not only helps to form a more uniform water film coverage, but also reduces local overheating or overcooling problems caused by uneven water flow, further improving the overall performance and stability of the system. Since the cooling water can be directly and evenly distributed to the surface of the heat exchange tube bank 110 under the guidance of the guide vanes 120, this not only improves the heat exchange efficiency, but also reduces the waste of water resources.

[0036] The first receiving cavity 150 has a volume of V1, and the second receiving cavity 160 has a volume of V2, satisfying V1:V2≥3. The larger first receiving cavity 150 can effectively store and buffer the incoming cooling water, ensuring a smooth and continuous water supply process and avoiding uneven water distribution caused by water flow fluctuations. It can achieve precise distribution and uniform outflow of cooling water. Because the second receiving cavity 160 has a smaller volume, the water flow velocity inside it is relatively faster, which helps the cooling water to pass through the water distribution channel more efficiently and be guided by the guide vanes 120 to the surface of the heat exchange tube bank 110, forming a more uniform water film distribution. (Refer to...) Figure 3 The water-stepping assembly 100 is generally A-shaped, with a first receiving cavity 150 formed at the upper end and a second receiving cavity 160 formed at the lower end. Located at the upper end of the assembly, the second receiving cavity 160 is designed with a larger volume. The larger first receiving cavity 150 acts as a buffer, ensuring sufficient space for initial distribution and stable flow of the incoming cooling water. This helps prevent uneven water flow caused by fluctuations in supply pressure, ensuring a smooth flow of water into the second receiving cavity 160.

[0037] The guide vanes 120 are arranged on both sides of the top of the heat exchange tube bank 110, and the guide vanes 120 on both sides are arranged in an opposing and staggered manner. This can avoid the problem of water flow deviating to one side that may be caused by unidirectional flow, and ensure that the cooling water can cover the entire heat exchange surface, thereby improving heat exchange efficiency.

[0038] Water guide holes 170 are spaced apart along the extension direction of the first receiving cavity 150. By spaced out the water guide holes 170 along the extension direction of the first receiving cavity 150, it can be ensured that cooling water can flow evenly from the first receiving cavity 150 into the second receiving cavity 160, avoiding the problem of excessively strong or weak water flow in local areas, and making the water flow into the second receiving cavity 160 more stable and evenly distributed.

[0039] The tips of the fins 130 of the heat exchange tube bank 110 are oriented towards the water distribution assembly 100. This directional design allows the cooling water to flow more effectively along the surface of the fins 130. This orientation helps ensure that the cooling water is quickly and evenly dispersed upon contact with the heat exchange tube bank 110, forming a continuous water film covering the entire heat exchange surface, thereby improving heat exchange efficiency.

[0040] The water distribution assembly 100 has a streamlined cross-section, and its projection towards the heat exchange tube bank 110 completely covers the outer contour of the heat exchange tube bank 110. This streamlined design reduces the obstruction of the water distribution assembly 100 to the airflow through the heat exchanger, allowing air to pass more smoothly through the heat exchange tube bank 110. This reduces air turbulence and increased resistance caused by structural irregularities or protrusions, thereby improving air cooling efficiency.

[0041] The water distribution assembly 100 also includes at least one secondary water supply hole 140, which is located in the middle section of the length of the water distribution assembly 100 and is connected to the first receiving cavity 150. This allows for the replenishment of water in the middle section, ensuring a more uniform distribution of cooling water along the entire length of the heat exchange tube bank 110.

[0042] The guide vane 120 is a mesh-like flow-guiding structure made of woven or stamped metal wire. The mesh structure can effectively disperse the water flow, avoiding local impact and uneven distribution caused by excessive water flow at a single point, so that the cooling water can more evenly cover the surface of the heat exchange tube bank 110 to form a continuous and stable water film.

[0043] The guide vane 120 is a flow guide strip made of flexible material. The flow guide strip made of flexible material can be finely adjusted according to the specific shape of the heat exchange tube bank 110 surface to ensure a tight fit. This helps to guide the cooling water to be distributed more evenly on the heat exchange surface, forming a continuous and stable water film, effectively avoiding the uneven water flow problem that may be caused by traditional rigid guide vanes 120.

[0044] The guide vane 120 is a wave-shaped flow-guiding structure formed by rolling the edge of the heat exchanger tube bank 110. The wave-shaped flow-guiding structure can more effectively guide the cooling water along a specific path. Compared to a flat guide vane 120, the wave-shaped design increases the length of the water flow path and the contact area, allowing the cooling water to be more evenly distributed on the surface of the heat exchanger tube bank 110, forming a continuous and stable water film, effectively avoiding localized dry spots or water accumulation. It is understood that the guide vane 120 can also be formed by stamping the heat exchanger tube bank 110, making the guide vane 120 integrally formed with the heat exchanger tube bank 110.

[0045] In this embodiment, a plurality of guide vanes 120 are evenly distributed along the heat sink at the top of the heat exchange tube bank 110. These guide vanes 120 adopt a wave-shaped flow-guiding structure formed by rolling the edge of the heat exchange tube bank 110 to guide the cooling water flow to and along the fins 130. First receiving cavity 150 and second receiving cavity 160: The water distribution assembly 100 is fixedly installed above the heat exchange tube bank 110, including the first receiving cavity 150 and the second receiving cavity 160, which extend along the straight pipe direction of the heat exchange tube bank 110. One end of the first receiving cavity 150 is connected to a water supply pipe, and the other end is sealed with a plug; the second receiving cavity 160 is connected to the first receiving cavity 150 through water guide holes 170, which are evenly distributed at the bottom of the first receiving cavity 150.

[0046] The water distribution assembly 100 also includes at least one secondary water supply hole 140, located in the middle section of the length of the water distribution assembly 100 and connected to the first receiving cavity 150, for replenishing the water volume in the middle section, ensuring a more uniform water flow distribution along the entire length of the heat exchange tube bank 110. The cross-section of the water distribution assembly 100 is streamlined, and its projection toward the heat exchange tube bank 110 completely covers the outer contour of the heat exchange tube bank 110, reducing airflow resistance and optimizing heat exchange efficiency.

[0047] During installation, first install the heat exchange tube bank 110, ensuring its correct positioning. Next, fix the water distribution assembly 100 above the heat exchange tube bank 110 according to design requirements, ensuring the accurate positioning of the first receiving cavity 150 and the second receiving cavity 160. Connect the water supply pipe to one end of the first receiving cavity 150 and seal the other end with a plug. Ensure the water guide holes 170 are evenly distributed at the bottom of the first receiving cavity 150 and check the secondary water supply hole 140 for unobstructed flow. If the water pressure in the first receiving cavity 150 does not meet the specified requirements, connect another water supply pipe to the secondary water supply hole 140 to ensure sufficient water pressure in the first receiving cavity 150.

[0048] Turn on the water supply system and observe the flow of cooling water after it enters the first receiving chamber 150. Ensure that the water flows smoothly into the second receiving chamber 160 through the water guide hole 170 and is guided by the guide vanes 120 to form a continuous water film on the surface of the heat exchange tube bank 110. Adjust the water supply flow rate and observe the working status of the secondary water replenishment hole 140 to ensure that it can provide additional water flow support when necessary and maintain the uniformity of water distribution. Check the operation of the entire system, especially the uniformity of water distribution and heat dissipation effect, and make fine adjustments according to actual needs until the optimal working state is achieved.

[0049] See attached document Figure 1 In the first embodiment, when the water pressure is sufficient, the water-stepping component 100 does not need to be equipped with a secondary water supply hole 140, as shown in the attached figure. Figure 5 In the second aspect embodiment, the water-stepping component 100 is provided with a secondary water supply hole 140 when the water pressure is insufficient, which can ensure that there is sufficient water pressure in the first receiving cavity 150.

[0050] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
