Description

Technical Field

[0001] This utility model relates to the field of water-based cold storage, and in particular to a water distribution system for improving cold storage capacity. Background Technology

[0002] In the field of water-based cooling systems, water-based cooling and heat storage are typically achieved by installing water distributors 42 at the top and bottom of the cooling storage space 4 (see reference). Figure 1 The water distributor 42 located at the bottom of the cold storage space 4 is connected to the outlet of the cold storage host and is used to inject cold water. The water distributor 42 located at the top of the cold storage space 4 is connected to the inlet of the host and is used to extract hot water, thereby realizing the replacement of cold and hot water in the cold storage space 4.

[0003] In the construction of existing cold storage spaces 4, multiple support beams 41 are generally arranged at intervals to enhance the strength of the top structure. However, this results in regularly distributed longitudinal cavities between adjacent support beams 41. When hot water is injected into the water distributor 42 located at the top of the cold storage space 4, some of the water flow directly impacts the support beam 41 structure, causing turbulence. This turbulence disrupts the stability of temperature stratification, intensifies the mixing of hot and cold water, and leads to an increase in the thickness of the temperature gradient layer. To avoid the above problems, the water distributor 42 located at the top of the cold storage space 4 is usually arranged below the support beams 41. The liquid level is lower than that of the support beams 41, which prevents the cavities from participating in the replacement of hot and cold water. This results in a decrease in the utilization rate of the top volume of the cold storage space 4 and a reduction in the overall cold storage efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a water distribution system that improves the cold storage capacity. It achieves secondary water distribution through a water distribution container to reduce the impact of turbulence on temperature stratification of the first water distribution component, thereby allowing it to be placed in the cavity and improving the utilization rate of the cold storage space.

[0005] The technical solution adopted by the water distribution system for improving cold storage capacity disclosed in this utility model is: The device includes a cold storage unit, a hot water pipe, and a cold water pipe. Multiple spaced crossbeams extend from the inner wall of the cold storage unit, forming a cavity between two adjacent crossbeams. The cavity is located near the top of the cold storage unit. Air guiding components are mounted on the crossbeams, with both ends of each component connected to the cavities on either side of the crossbeam. The hot water pipe extends into the cold storage unit and is connected to multiple first water distribution components. A water distribution container with multiple water distribution holes is located on the outer side of each first water distribution component and is placed within the cavity. The cold water pipe extends into the cold storage unit and is connected to multiple second water distribution components, located near the bottom of the cold storage unit.

[0006] As a preferred embodiment, the crossbeam is provided with a flow guiding component, and the two ends of the flow guiding component are respectively connected to the water distribution containers on both sides of the crossbeam.

[0007] As a preferred embodiment, the air guiding assembly includes an air guiding pipe, the two ends of which are respectively connected to two adjacent cavities and the air guiding pipe is connected to a water distribution container. The flow guiding assembly includes a flow guiding pipe, the two ends of which are respectively connected to two adjacent water distribution containers.

[0008] As a preferred embodiment, the water distribution container has a box structure with an open top, and the water distribution hole is located at the bottom of the water distribution container and penetrates through the water distribution container.

[0009] As a preferred embodiment, the water distribution container is fixedly connected to both sides with a first buckle and a second buckle, the air guide tube is inserted into the adjacent first buckle, and the flow guide tube is inserted into the adjacent second buckle.

[0010] As a preferred embodiment, the first water distribution component includes a first water distributor, the passage of which passes through the water distribution container and is connected to the hot water pipe.

[0011] As a preferred embodiment, the second water distribution assembly includes a second water distributor, the passage of which is connected to a cold water pipe.

[0012] The beneficial effects of the water distribution system for improving cold storage capacity disclosed in this utility model are: The outlet of the external chiller is connected to the hot water pipe, and the inlet of the external chiller is connected to the cold water pipe. When the external chiller starts up and draws cold water from the cold storage device, cold water located at the bottom of the cold storage device is drawn through the cold water pipe and the second water distribution assembly. After heat exchange in the external chiller, the cold water is converted into hot water and then transported to the water distribution container through the hot water pipe and the first water distribution assembly. The water distribution container is used to buffer the impact of the hot water output by the first water distribution assembly and reduce the water flow disturbance. Then, secondary water distribution is carried out through the water distribution holes, thereby reducing the impact of the first water distribution assembly on temperature stratification. This design allows the first water distribution assembly to be installed in the cavity between two adjacent crossbeams, effectively improving the space utilization of the cold storage device. To avoid inconsistent air pressure in multiple cavities, air guiding components are used to connect the cavities, allowing air to flow freely between them, thereby maintaining the same air pressure in all cavities.

[0018] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings: Example 1, please refer to Figures 2-5 .

[0019] This utility model discloses a water distribution system for improving cold storage capacity, including a cold storage device 1, a hot water pipe 12 and a cold water pipe 13; In this embodiment, the preferred cold storage device 1 is a cold water storage tank, but it is not limited to this. It can also be a cold storage tank, a cold water storage container, or other cold storage structures with the same function. The cold storage device 1 has a cold storage space for storing cold water. When the volume of the cold storage space is too large, the top of the cold storage space needs to be reinforced for support. Multiple horizontal beams 11 are arranged at intervals on the inner wall of the cold storage device 1. The horizontal beams 11 are located at the top of the cold storage space and are used to reinforce the top of the cold storage space. A cavity is formed between two adjacent horizontal beams 11, and the cavity is close to the top of the cold storage device 1.

[0020] Hot water pipe 12 is inserted into cold storage device 1. Multiple first water distribution components 2 are connected to hot water pipe 12. The first water distribution component 2 includes a first water distributor 21. The passage of the first water distributor 21 is connected to hot water pipe 12. Furthermore, a water distribution container 22 is provided on the outside of the first water distribution component 2. In this embodiment, the water distribution container 22 preferably has a box structure with an open top. The first water distributor 21 is located inside the water distribution container 22. The water distribution container 22 is placed in the cavity. The first water distributor 21 faces the bottom of the water distribution container 22. The passage of the first water distributor 21 passes through the bottom of the water distribution container 22 and is connected to the hot water pipe 12. A plurality of water distribution holes 221 are opened at the bottom of the water distribution container 22. The water distribution holes 221 pass through the water distribution container 22. In this embodiment, the plurality of water distribution holes 221 are arranged in a rectangular array. Furthermore, both sides of the water distribution container 22 are fixedly connected with a first buckle 222 and a second buckle 223.

[0021] The crossbeam 11 is provided with an air guiding assembly 14, and the two ends of the air guiding assembly 14 are respectively connected to the cavities on both sides of the crossbeam 11. Furthermore, the air guiding assembly 14 includes an air guiding pipe 141; both ends of the air guiding pipe 141 are respectively connected to two adjacent cavities, and both ends of the air guiding pipe 141 are above the liquid level; both ends of the air guiding pipe 141 are covered with a waterproof and breathable membrane. In this embodiment, the waterproof and breathable membrane is preferably made of ePTFE microporous membrane to prevent cold water from entering the air guiding pipe 141 and affecting the air circulation inside the air guiding pipe 141; both ends of the air guiding pipe 141 are respectively snapped into adjacent first buckles 222, thereby fixing the air guiding pipe 141 in the cold storage device 1; Multiple air ducts 141 connect multiple cavities, allowing air in one cavity to flow to another cavity through the air duct 141, thereby maintaining a consistent air pressure in each cavity.

[0022] A flow guiding component 15 is provided on the crossbeam 11, and the two ends of the flow guiding component 15 are respectively connected to the water distribution containers 22 on both sides of the crossbeam 11. Furthermore, the flow guiding assembly 15 includes a flow guiding pipe 151; both ends of the flow guiding pipe 151 are respectively connected to two adjacent water distribution containers 22, and the end of the flow guiding pipe 151 is close to the edge of the water distribution container 22; both ends of the flow guiding pipe 151 are respectively snapped into adjacent second buckles 223, thereby fixing the flow guiding pipe 151 in the cold storage device 1. Since the hot water output flow rate of each first water distributor 21 is different, multiple guide pipes 151 are used to connect the water distribution containers 22 in each cavity to each other. When the liquid level in one of the water distribution containers 22 rises to exceed the height of the guide pipe 151, the hot water will automatically flow through the guide pipe 151 to the adjacent water distribution container 22 with a lower liquid level, thereby achieving liquid level balance among the water distribution containers 22 and avoiding uneven hydraulic distribution caused by excessive hot water input flow rate in local areas.

[0023] A cold water pipe 13 is inserted into the cold storage device 1. Multiple second water distribution components 3 are connected to the cold water pipe 13. The second water distribution components 3 are close to the bottom of the cold storage device 1. Furthermore, the second water distribution assembly 3 includes a second water distributor 31; the passage of the second water distributor 31 is connected to the cold water pipe 13.

[0024] When cooling: The outlet of the external chiller is connected to the hot water pipe 12, and the inlet of the external chiller is connected to the cold water pipe 13. The external chiller starts up and draws cold water from the bottom of the cold storage device 1 through the cold water pipe 13 and the second water distributor 31. After the cold water completes heat exchange in the external chiller, it is converted into hot water and then transported to the water distribution container 22 through the hot water pipe 12 and the first water distributor 21 for the first buffering and water distribution. The water distribution container 22 is used to buffer the impact of the hot water output from the first water distribution component 2 and reduce the water flow disturbance. The hot water flows out of the water distribution container 22 through the water distribution hole 221 for the second water distribution.

[0025] During cold storage: The inlet of the external cold storage unit is connected to the hot water pipe 12, and the outlet of the external cold storage unit is connected to the cold water pipe 13. The external cold storage unit starts up and draws hot water from the top of the cold storage device 1 through the hot water pipe 12, the first water distributor 21 and the water distribution hole 221. The external cold storage unit converts the hot water into cold water, which is then transported to the cold storage device 1 through the cold water pipe 13 and the second water distributor 31 for cold storage.

[0026] Example 2, please refer to Figures 2-5 .

[0027] Based on Embodiment 1, one or more first water distributors 21 and matching water distribution containers 22 can be configured according to the volume of the cavity; when multiple first water distributors 21 are used, the multiple first water distributors 21 are arranged in a rectangular array in the cavity, which can improve the water distribution efficiency of a single cavity.

[0028] This utility model provides a water distribution system to improve the cold storage capacity, wherein the outlet of the external chiller is connected to a hot water pipe and the inlet of the external chiller is connected to a cold water pipe. When the external chiller starts up and draws cold water from the cold storage device, cold water located at the bottom of the cold storage device is drawn through the cold water pipe and the second water distribution assembly. After heat exchange in the external chiller, the cold water is converted into hot water and then transported to the water distribution container through the hot water pipe and the first water distribution assembly. The water distribution container is used to buffer the impact of the hot water output by the first water distribution assembly and reduce the water flow disturbance. Then, secondary water distribution is carried out through the water distribution holes, thereby reducing the impact of the first water distribution assembly on temperature stratification. This design allows the first water distribution assembly to be installed in the cavity between two adjacent crossbeams, effectively improving the space utilization of the cold storage device. To avoid inconsistent air pressure in multiple cavities, air guiding components are used to connect the cavities, allowing air to flow freely between them, thereby maintaining the same air pressure in all cavities.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
