Description

Technical Field

[0001] This utility model relates to the field of chiller technology, and in particular to a centralized cooling device for a chiller. Background Technology

[0002] A chiller (also known as a freezer, refrigeration unit, ice water unit, or cooling equipment) is a refrigeration device. The basic working principle of a chiller is as follows: The compressor draws in low-temperature, low-pressure refrigerant gas after evaporation and cooling, then compresses it into high-temperature, high-pressure gas, which is then sent to the condenser. The high-pressure, high-temperature gas is cooled by the condenser, causing it to condense into a room-temperature, high-pressure liquid. This liquid then flows into the thermal expansion valve, where it is throttled into low-temperature, low-pressure wet vapor, which flows into the shell-and-tube evaporator, absorbing heat from the chilled water and lowering its temperature. The evaporated refrigerant is then drawn back into the compressor, repeating the next refrigeration cycle.

[0003] In large-scale cooling systems, multiple chillers often need to operate simultaneously to meet cooling demands. A centralized cooling system is typically used to collect the cooling water output from the chillers before distributing it. Currently, existing centralized cooling systems usually consist of a central tank, output pipes, and several input pipes. The cooling water from the chillers enters the central tank through the input pipes. However, when a chiller malfunctions and cannot supply water to the central tank, it is difficult for staff to detect, leading to reduced cooling efficiency. Furthermore, the cooling water in the central tank can easily flow back to the malfunctioning chiller under water pressure, causing adverse effects. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a centralized cooling device for a chiller.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a centralized cooling device for a chiller, comprising a centralized box, wherein a plurality of water inlet components are spaced apart on one side of the centralized box, and an output pipe is connected to the centralized box. The water inlet components include a horizontal pipe disposed on the side wall of the centralized box, one end of the horizontal pipe located inside the centralized box is connected to a vertical pipe, a sliding pipe is slidably disposed inside the lower end of the vertical pipe, a base plate is disposed at the lower end of the sliding pipe, an elastic unit is disposed on the vertical pipe to provide an upward thrust to the base plate, a plurality of first through holes are circumferentially spaced apart at the lower part of the vertical pipe, a plurality of second through holes are circumferentially spaced apart at the sliding pipe, a connecting rod is horizontally disposed on the base plate, and an opening is opened on the side wall of the centralized box corresponding to the water inlet components, and a glass plate is disposed in the opening.

[0006] By adopting the above technical solution, a central tank, vertical pipe, sliding pipe, elastic unit, first through hole, and second through hole are installed. Cooling water output from the chiller enters the vertical pipe through the horizontal pipe. Under water pressure, it pushes the sliding pipe and base plate downwards until the first and second through holes coincide. Cooling water then enters the central tank through the first and second through holes and is subsequently output from the outlet pipe. During the downward movement of the base plate, the connecting rod descends. The position of the connecting rod is observed through a glass plate to determine whether it has descended, thus indicating whether cooling water is flowing out of the corresponding vertical pipe. This facilitates observation by staff, enabling fault detection and resolution, and ensuring effective cooling. When no cooling water flows out of the vertical pipe, the elastic unit pushes the base plate and sliding pipe upwards, causing the first and second through holes to misalign, preventing water in the central tank from flowing back into the vertical pipe.

[0007] Furthermore, a vertically arranged mounting plate is provided at the end of the connecting rod away from the base plate, and red plates and green plates are vertically spaced apart on the side of the mounting plate away from the connecting rod.

[0008] By adopting the above technical solution, with the installation plate, red plate, and green plate set up, and the second through hole offset from the first through hole, the red plate is located at the glass plate. The base plate descends, causing the connecting rod, installation plate, red plate, and green plate to descend as well, moving the green plate to the glass plate for easier observation by staff.

[0009] Furthermore, the elastic unit includes a mounting ring disposed at the lower end of the vertical tube. Several vertically arranged guide rods are circumferentially spaced on the bottom surface of the mounting ring. Guide holes are provided on the base plate corresponding to the guide rods. The guide holes are slidably connected to the corresponding guide rods. A baffle is provided at the lower end of the guide rod. A compression spring is sleeved on the rod body of the guide rod located between the baffle and the base plate.

[0010] By adopting the above technical solution, and setting up an installation ring, guide rod, baffle, and compression spring, after cooling water enters the vertical pipe, the water flow, under the action of water pressure, pushes the sliding tube and the base plate to slide, the compression spring is compressed, and the guide rod ensures the stability of the base plate sliding. After the cooling water stops entering the vertical pipe, the compression spring provides elastic force, causing the base plate and sliding tube to rise, and the base plate contacts the installation ring, with the first through hole and the second through hole offset.

[0011] Furthermore, an annular groove is formed on the outer wall of the sliding tube, and an annular rubber ring is provided in the annular groove. The outer wall of the annular rubber ring abuts against the inner wall of the vertical tube.

[0012] Furthermore, the inner wall of the central box is provided with connecting blocks on both the upper and lower sides of the opening, and two sliding rods are provided between the two connecting blocks. The mounting plate has sliding holes corresponding to the sliding rods, and the sliding holes are slidably connected to the corresponding sliding rods.

[0013] By adopting the above technical solution, a connecting block, a sliding rod, and a sliding hole are set up, and the mounting plate slides on the sliding rod, ensuring the stability of the mounting plate sliding.

[0014] Furthermore, a limiting tube is sleeved on the guide rod, and the lower end of the limiting tube is connected to the baffle.

[0015] By adopting the above technical solution, a limiting tube is sleeved on the guide rod to limit the movement stroke of the base plate.

[0016] Furthermore, the edge of the first through hole near the sliding tube is rounded.

[0017] In summary, this utility model has the following beneficial effects: This application includes a central collection box, a vertical pipe, a sliding pipe, an elastic unit, a first through hole, and a second through hole. Cooling water output from the chiller enters the vertical pipe through the horizontal pipe. Under water pressure, it pushes the sliding pipe and the base plate downwards until the first and second through holes coincide. Cooling water then enters the central collection box through the first and second through holes and is subsequently output from the output pipe. During the downward movement of the base plate, the connecting rod descends. By observing the position of the connecting rod through a glass plate, it can be determined whether the connecting rod has descended, thus indicating whether cooling water is flowing out of the corresponding vertical pipe. This facilitates observation by staff, enabling fault detection and resolution, and ensuring the cooling effect. Furthermore, when no cooling water flows out of the vertical pipe, the elastic unit pushes the base plate and the sliding pipe upwards, causing the first and second through holes to misalign, preventing water in the central collection box from flowing back into the vertical pipe.

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] like Figure 1-5 As shown in the figure, this application discloses a centralized cooling device for a chiller, including a centralized box 10, a sliding tube 23, an elastic unit 30, a first through hole 25, and a second through hole 26. A plurality of water inlet components 20 are spaced apart on one side of the centralized box 10, each water inlet component 20 corresponding to a chiller. An output pipe 11 is connected to the centralized box 10. Each water inlet component 20 includes a horizontal pipe 21 disposed on the side wall of the centralized box 10. One end of the horizontal pipe 21 is located outside the centralized box 10 and connected to the chiller's pipe. The other end of the horizontal pipe 21 is located inside the centralized box 10 and connected to a vertical pipe 22. A sliding tube 23 is slidably disposed inside the lower end of the vertical pipe 22. A base plate 24 is disposed at the lower end of the sliding tube 23. The elastic unit 30 is disposed on the vertical pipe 22 and is used to provide an upward thrust to the base plate 24. The lower part of the vertical pipe 22 is provided with a number of first through holes 25 spaced apart circumferentially, and the sliding pipe 23 is provided with a number of second through holes 26 spaced apart circumferentially. When the first through holes 25 and the second through holes 26 are staggered, the cooling water cannot flow between the vertical pipe 22 and the central box 10.

[0026] A connecting rod 27 is horizontally mounted on the base plate 24. An opening 12 is provided on the side wall of the central storage box 10 corresponding to the water inlet assembly 20, and a glass plate 13 is installed inside the opening 12. Cooling water output from the chiller enters the vertical pipe 22 through the horizontal pipe 21. Under water pressure, it pushes the sliding pipe 23 and the base plate 24 downward until the first through hole 25 and the second through hole 26 coincide. The cooling water then enters the central storage box 10 through the first through hole 25 and the second through hole 26, and is subsequently output from the output pipe 11. During the downward movement of the base plate 24, the connecting rod 27 descends. By observing the position of the connecting rod 27 through the glass plate 13, it can be determined whether the connecting rod 27 has descended, thus indicating whether cooling water is flowing out of the corresponding vertical pipe 22. This facilitates observation by staff, enabling them to identify and resolve faulty chillers and ensure effective cooling. When no cooling water flows out of the vertical pipe 22, the elastic unit 30 pushes the base plate 24 and the sliding pipe 23 to rise, and the first through hole 25 and the second through hole 26 are misaligned, so that the water in the collection box 10 cannot enter the vertical pipe 22 for backflow.

[0027] Specifically, a vertically arranged mounting plate 28 is provided at the end of the connecting rod 27 away from the base plate 24. A red plate 281 and a green plate 282 are vertically spaced at intervals on the side of the mounting plate 28 away from the connecting rod 27. When the second through hole 26 is offset from the first through hole 25, the red plate 281 is located at the glass plate 13. The descent of the base plate 24 causes the connecting rod 27, mounting plate 28, red plate 281, and green plate 282 to descend, moving the green plate 282 to the glass plate 13 for easier observation by staff. Connecting blocks 40 are provided on both the upper and lower sides of the opening 12 on the inner wall of the collection box 10. Two vertically arranged sliding rods 41 are provided between the two connecting blocks 40. Sliding holes are provided on the mounting plate 28 corresponding to the sliding rods 41, and these holes are slidably connected to the corresponding sliding rods 41. The mounting plate 28 slides on the sliding rods 41, ensuring the stability of the sliding of the mounting plate 28.

[0028] In configuration, the elastic unit 30 includes a mounting ring 31 and guide rods 32. The mounting ring 31 is located at the lower end of the vertical pipe 22. Several guide rods 32 are arranged vertically and spaced circumferentially on the bottom surface of the mounting ring 31. A guide hole is provided on the base plate 24 corresponding to the guide rod 32, and the guide hole is slidably connected to the corresponding guide rod 32. A baffle 33 is provided at the lower end of the guide rod 32. A compression spring 34 is sleeved on the rod body of the guide rod 32 located between the baffle 33 and the base plate 24. The upper end of the compression spring 34 is connected to the base plate 24, and the lower end is connected to the baffle 33. After cooling water enters the vertical pipe 22, the water flow pushes the sliding pipe 23 and the base plate 24 to slide under water pressure, compressing the compression spring 34. The guide rods 32 ensure the stability of the sliding of the base plate 24. After the cooling water stops entering the vertical pipe 22, the compression spring 34 provides elastic force, causing the base plate 24 and sliding pipe 23 to rise. The base plate 24 contacts the mounting ring 31, and the first through hole 25 and the second through hole 26 are offset. A limiting tube 35 is sleeved on the guide rod 32. The lower end of the limiting tube 35 is connected to the baffle 33 to limit the movement stroke of the base plate 24 and ensure the stability of the first through hole 25 and the second through hole 26 coinciding.

[0029] In a specific configuration, an annular groove is formed on the outer wall of the sliding tube 23, and an annular rubber ring 29 is placed inside the annular groove. The outer wall of the annular rubber ring 29 abuts against the inner wall of the vertical tube 22, enhancing the sealing between the sliding tube 23 and the vertical tube 22. To prevent the relatively sharp edge of the first through hole 25 from scratching the annular rubber ring 29 when the sliding tube 23 moves, a rounded corner is provided on the edge of the first through hole 25 near the sliding tube 23.

[0030] The operating principle of the centralized cooling device for a chiller in this embodiment is as follows:

[0031] Cooling water output from the chiller enters the vertical pipe 22 through the horizontal pipe 21. Under water pressure, it pushes the sliding pipe 23 and the base plate 24 downwards until the base plate 24 contacts the upper end of the limiting pipe 35. At this time, the first through hole 25 and the second through hole 26 coincide, and the cooling water enters the collection box 10 through the first through hole 25 and the second through hole 26, and then exits from the output pipe 11. During the downward movement of the base plate 24, it drives the connecting rod 27 mounting plate 28, the red plate 281, and the green plate 282 to descend, causing the green plate 282 to move to the glass plate 13. By observing whether the red plate 281 or the green plate 282 is at the glass plate 13, the operator can determine whether the connecting rod 27 has descended, and thus know whether there is cooling water flowing out of the corresponding vertical pipe 22.

[0032] When no cooling water flows out of the vertical pipe 22, the compression spring 34 pushes the base plate 24 and the sliding pipe 23 to rise under the action of elasticity. The first through hole 25 and the second through hole 26 are misaligned, so that the water in the collection box 10 cannot enter the vertical pipe 22 for backflow.

[0033] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
