Description

Technical Field

[0001] This utility model relates to the field of water manifolds, and more particularly to a high-efficiency water manifold for industrial cooling systems. Background Technology

[0002] In large industrial facilities such as data centers, pharmaceutical plants, chemical plants, and central air conditioning systems, the cooling system is a core infrastructure that ensures continuous and stable operation. As a key distribution and collection device in the cooling circulation system, the performance of the manifold directly affects the energy consumption, cooling efficiency, and operational reliability of the entire system.

[0003] Currently, common manifold designs typically install flow control valves at each branch pipe connection (e.g., patent "An Assembled Manifold (CN222392284U)") to achieve independent flow control for each branch. However, this design has the following significant problems: High cost: Installing flow control valves at each branch pipe connection significantly increases the manufacturing cost of the manifold, as each valve requires separate design, manufacturing, and installation, increasing not only the number of parts but also the complexity of the mechanical structure. Inconvenient manual operation: Existing manifolds usually require manual adjustment of the flow control valves at each branch pipe connection to ensure balanced flow across all branches. In industrial cooling systems, this manual operation is not only inefficient but also makes precise flow control difficult, especially during system operation. Frequent manual intervention can lead to operational errors, affecting system stability and reliability. Lack of filtration function: Existing manifolds typically do not have internal filtration, making it impossible to effectively intercept impurities in the cooling water. Over time, these impurities may accumulate in pipes and equipment, causing blockages, wear and tear, and reduced cooling efficiency. They may even lead to system failures, increasing maintenance costs and downtime. Summary of the Invention

[0004] The present invention aims to address the shortcomings of the prior art by providing a high-efficiency water manifold for industrial cooling systems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency water distribution manifold for industrial cooling systems, comprising a main water collection pipe, which is a horizontally placed box-shaped structure with a flat top and a round bottom. One end of the main water collection pipe has a water inlet, and the top has several branch pipe connection ports along the axial direction for connecting external branch pipes. The internal flow channel of each branch pipe connection port is an integrally made Venturi tube structure. Supports are provided at both ends of the bottom of the main water collection pipe, and a pluggable filter assembly is provided inside near the water inlet.

[0006] In particular, the Venturi tubular structure inside the branch pipe connection includes a converging section, a throat, and a dilating section in sequence along the fluid direction, and the throat diameter of the branch pipe connection is smaller the closer it is to the inlet.

[0007] Specifically, the filter assembly includes an opening at the top of the main water collection pipe, a frame welded to the top edge of the opening, a slot on the inner wall of the main water collection pipe corresponding to the opening, a filter screen plate that slides into the slot, a sealing plate inserted in the frame and a cover plate that is bolted to the top to press the sealing plate, the top of the filter screen plate and the top of the slot being flush, and both the top of the filter screen plate and the top of the sealing plate being fitted with hinged pull rings.

[0008] Specifically, the bottom of the main water collection pipe is equipped with a backwash port and a drain port. The backwash port is located on the downstream side of the filter screen plate, and the drain port is located on the upstream side of the filter screen plate. The backwash port is connected to a pressurized water source for introducing backwash water flow.

[0009] Specifically, the support includes an arc-shaped pad welded to the bottom of the main water collection pipe, a vertical plate fixed to the outer wall of the arc-shaped pad, and a horizontal plate fixed to the bottom of the vertical plate. The horizontal plate has elongated bolt holes at its four corners.

[0010] In particular, the top of the main water collection pipe is also integrated with an instrument interface platform for mounting one or more of a pressure sensor, temperature sensor, or flow meter.

[0011] Specifically, the main water collection pipe is made of carbon steel, with its inner wall lined with a stainless steel liner or coated with an anti-corrosion coating.

[0012] The beneficial effects of this utility model are:

[0013] This invention utilizes a Venturi tube structure within the internal flow channels of each branch pipe connection to automatically distribute water flow based on fluid mechanics principles, achieving dynamic balance of flow rate across each branch. This design eliminates the need for additional flow control valves, significantly reducing costs while simultaneously improving system stability and reliability, ensuring efficient operation of the cooling system.

[0014] This invention, through the installation of a pluggable filter assembly, effectively intercepts impurities in the cooling water, preventing them from entering the cooling system, extending equipment lifespan, and reducing maintenance costs and downtime. Furthermore, the pluggable design of the filter assembly facilitates regular cleaning and filter replacement, making maintenance simple and efficient. Simultaneously, the inclusion of a backwash port and a drain port allows for the introduction of reverse flushing water, enabling online cleaning of the filter assembly without system downtime, significantly improving system operating efficiency and maintenance convenience.

[0015] This invention allows for lateral adjustment during installation by opening elongated bolt holes at the bottom of the bracket, effectively compensating for installation deviations and preventing stress from occurring in pipe connections. Attached Figure Description

[0021] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0023] like Figures 1-4 As shown, a high-efficiency water distribution manifold for industrial cooling systems includes a main water collection pipe 1. The main water collection pipe 1 is a horizontally placed box-shaped structure with a flat top and a round bottom, which ensures that the top has a sufficient flat surface for installing branch pipe connection ports 3, openings 51 and instrument interface platforms 8, while also ensuring pressure resistance and fluid flow.

[0024] The main water collection pipe 1 has an inlet 2 at one end of its top. Along the axial direction at the top, there are several branch pipe connection ports 3 for connecting to external branch pipes. These connection ports have standard flange faces for connecting to external branch pipes. The internal flow channel of each branch pipe connection port 3 is a monolithically formed Venturi tubular structure. The Venturi tubular structure, along the fluid direction, includes a converging section, a throat, and a diverging section. The closer the branch pipe connection port 3 is to the inlet 2, the smaller its throat diameter. The internal flow channel of each branch pipe connection port 3 is integrally formed into a Venturi tubular structure during casting or machining, and this structure is smoothly transitioned from the converging section to the throat and then to the diverging section. Based on fluid mechanics principles, the throat diameter of the branch pipe connection ports 3 at different distances from the inlet 2 is designed differently, with a smaller throat diameter at the near end and a larger throat diameter at the far end. This provides greater additional flow resistance to the near-end branch, ultimately achieving automatic flow balance across all branches during operation.

[0025] This invention utilizes a Venturi tube structure within the internal flow channels of each branch pipe connection 3, automatically distributing water flow based on fluid mechanics principles to achieve dynamic balance of flow in each branch. This design eliminates the need for additional flow control valves, significantly reducing costs while improving system stability and reliability, ensuring efficient operation of the cooling system.

[0026] The bottom of the main water collection pipe 1 is equipped with supports 4 at both ends. The supports 4 include an arc-shaped pad 41 welded to the bottom of the main water collection pipe 1, a vertical plate 42 fixed to the outer wall of the arc-shaped pad 41, and a horizontal plate 43 fixed to the bottom of the vertical plate 42. The horizontal plate 43 has elongated bolt holes 44 at its four corners. The elongated bolt holes 44 allow for fine-tuning of the entire device before tightening the anchor bolts to ensure perfect alignment with the pipeline.

[0027] A pluggable filter assembly 5 is located inside the main water collection pipe 1 near the inlet 2. The filter assembly 5 includes an opening 51 at the top of the main water collection pipe 1, a frame 52 welded to the top edge of the opening 51, a slot 53 on the inner wall of the main water collection pipe 1 corresponding to the opening 51, and a filter screen plate 54 that slides into the slot 53. A sealing plate 55 is inserted into the frame 52, and a cover plate 56 that presses the sealing plate 55 is bolted to the top. The top of the filter screen plate 54 is flush with the top of the slot 53, and both the top of the filter screen plate 54 and the top of the sealing plate 55 are fitted with hinged pull rings 57. The bottom of the main water collection pipe 1 has a backwash port 6 and a drain port 7. The backwash port 6 is located downstream of the filter screen plate 54, and the drain port 7 is located upstream of the filter screen plate 54. The backwash port 6 and the drain port 7 are equipped with valves. The backwash port 6 is connected to a pressurized water source for introducing backwash water. During maintenance, first open the bolted cover plate 56, remove the sealing plate 55, and then use the pull ring 57 to lift the filter screen plate 54 for cleaning. The operation is extremely convenient. At the bottom of the main water collection pipe 1, a backwash port 6 and a drain port 7 are provided corresponding to the position of the filter screen plate 54. When needed, high-pressure water can be introduced to backwash the filter screen and discharge impurities from the drain port 7.

[0028] This invention, by incorporating a pluggable filter assembly 5, effectively intercepts impurities in the cooling water, preventing them from entering the cooling system, extending equipment lifespan, and reducing maintenance costs and downtime. Furthermore, the pluggable design of the filter assembly 5 facilitates regular cleaning and filter replacement, making maintenance simple and efficient. Simultaneously, the inclusion of a backwash port 6 and a drain port 7 allows for the introduction of backwash water, enabling online cleaning of the filter assembly 5 without system downtime, significantly improving system operating efficiency and maintenance convenience.

[0029] The top of the main water collection pipe 1 is also integrated with an instrument interface platform 8, which has multiple pre-drilled threaded holes or pipe flanges for installing one or more of pressure sensors, temperature sensors or flow meters to achieve functional integration.

[0030] The main water collection pipe 1 is made of carbon steel to ensure its strength. Its inner wall is lined with stainless steel or coated with an anti-corrosion coating to resist the corrosion of industrial cooling water and extend the service life of the equipment.

[0031] In operation, cooling water enters the main water collection pipe 1 through the inlet 2, first passing through the filter screen 54 to intercept impurities. Then, the cooling water flows to each branch pipe connection port 3. Because each connection port integrates a precisely calculated Venturi tube, the water flow is automatically distributed, maintaining dynamic flow balance across branches even with system pressure fluctuations. Integrated instruments monitor the system status in real time. When the filter screen 54 needs cleaning, it can be lifted for cleaning by opening the cover plate 56 and sealing plate 55, or the backwash function can be activated for online cleaning, making maintenance simple and efficient.
