Description

Technical Field

[0001] The utility model relates to the technical field of cooling equipment, in particular to a high-efficiency segmented water storage cooling device. Background Art

[0002] With the continuous development of modern industrial technology, the demand for cooling in large buildings, data centers, factories and other places is increasing. Especially during the hot summer period, the cooling systems in these places need to bear huge loads to ensure the normal operation of the equipment and the comfort of the environment. Traditional cooling systems often use direct cooling methods, such as using chillers to directly cool the room, but this method often consumes a lot of electricity during peak hours and has a relatively low energy efficiency ratio.

[0003] In order to meet this challenge, cold storage technology has gradually been widely used. Cold storage technology stores cold energy during low-power consumption periods and releases it during peak power consumption periods to reduce the load on the power grid and improve energy efficiency. In water cold storage technology, water is used as a carrier of cold energy. The cold water is stored in a water storage tank through a refrigeration unit, and then the cold water is transported to the cooling terminal for cooling through a circulating pump when needed.

[0004] However, traditional water storage cooling devices often have some problems. First, due to the poor thermal conductivity of water, the cold storage efficiency is not high. Second, traditional devices often use a single water storage tank design, which cannot achieve segmented cold storage, thus limiting its scope of application and flexibility. In addition, during the long-term operation of traditional devices, impurities and dirt are easily accumulated in the pipelines, causing pipeline blockage and affecting the normal operation of the system. Utility Model Content

[0005] The purpose of the utility model is to provide an efficient segmented water storage and cooling device to solve the problem that the thermal conductivity of water is poor, resulting in low cold storage efficiency. Secondly, the traditional device cannot achieve segmented cold storage, which limits its scope of application and flexibility. In addition, during the long-term operation of the traditional device, impurities and dirt are easily accumulated in the pipeline, resulting in pipeline blockage, affecting the normal operation of the system.

[0006] To achieve the above-mentioned purpose, the utility model provides a high-efficiency segmented water storage and cooling device, comprising two water storage tanks, the top of the water storage tank is connected to an upper cold storage unit and an upper terminal device through a water supply pipeline, the bottom of the water storage tank is connected to a lower cold storage unit and a lower terminal device through a pipeline, the upper cold storage unit is connected to the lower cold storage unit, the upper terminal device is connected to the lower terminal device, and an anti-blocking component is installed in the middle of the water supply pipelines at the upper and lower ends of the water storage tank.

[0007] Preferably, an upper water inlet valve is installed on the input end pipeline of the upper terminal device, and an upper water outlet valve is installed on the output end pipeline of the upper terminal device.

[0008] Preferably, the input end pipeline of the lower terminal device is installed with a lower water inlet valve, and the output end pipeline of the lower terminal device is installed with a lower water outlet valve.

[0009] Preferably, the anti-clogging component includes a horizontally arranged straight pipe, the bottom of both ends of the straight pipe are connected to a U-shaped pipe, both ends of the U-shaped pipe are connected to a water supply pipeline, a flushing interface is installed in the middle of the straight pipe, a sealing cover is installed at the flushing interface, a sewage outlet is installed at the bottom of one end of the U-shaped pipe, and a sealing plug is installed at the sewage outlet.

[0010] Preferably, valves are installed at both ends of the U-shaped tube.

[0011] Preferably, a plurality of slow-flow baffles are installed vertically at equal intervals inside the water storage tank.

[0012] Preferably, a water level observation pipeline is vertically installed on the outer side of the water storage tank, and both ends of the water level observation pipeline are connected to the water delivery pipeline.

[0013] Preferably, the water delivery pipeline is of a U-shaped structure, with both ends connected to left and right water storage tanks respectively.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] In this high-efficiency segmented water storage cooling device, by adopting a segmented cold storage design, the device realizes stratified storage of cold water in different water storage tanks, thereby improving the cold storage efficiency. The upper cold storage unit is connected to the upper terminal equipment, and the lower cold storage unit is connected to the lower terminal equipment. The cold storage and cooling capacity of each part can be flexibly adjusted according to actual needs, meeting the changes in cooling needs in different places.

[0016] The introduction of anti-clogging components has greatly enhanced the anti-clogging ability of the system. When impurities and dirt accumulate in the pipeline, you can open the flushing interface of the anti-clogging component and use high-pressure water flow to clean it, effectively removing the blockage in the pipeline. At the same time, the setting of the sewage outlet also makes it easy to discharge the cleaned impurities and dirt out of the system, ensuring the smooth flow of the pipeline.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides a high-efficiency segmented water storage cooling device, such as Figure 1-Figure 3 As shown, it includes two water storage tanks 1, the top of the water storage tank 1 is connected to an upper cold storage unit 3 and an upper terminal device 5 through a water delivery pipeline 2, and the bottom of the water storage tank 1 is connected to a lower cold storage unit 4 and a lower terminal device 6 through a pipeline. The upper cold storage unit 3 is connected to the lower cold storage unit 4, and the upper terminal device 5 is connected to the lower terminal device 6. By sending water into the upper cold storage unit 3 and then into the lower cold storage unit 4, a two-level cold storage operation is achieved. By sending water first into the lower terminal device 6 and then into the upper terminal device 5, a cooling operation for multiple devices is achieved. Anti-blocking components 7 are installed in the middle of the water delivery pipelines 2 at the upper and lower ends of the water storage tank 1 to prevent blockage in the pipeline that is inconvenient to clean.

[0024] In this embodiment, the input end pipeline of the upper terminal device 5 is installed with an upper water inlet valve 51, and the output end pipeline of the upper terminal device 5 is installed with an upper water outlet valve 52, so that water can enter the upper terminal device 5 to cool the device and then be discharged to the outside.

[0025] Specifically, the input end pipeline of the lower terminal device 6 is installed with a lower water inlet valve 61, and the output end pipeline of the lower terminal device 6 is installed with a lower water outlet valve 62, so that water can enter the lower terminal device 6 to cool the device and then be discharged to the outside.

[0026] Furthermore, the anti-clogging component 7 includes a horizontally arranged straight pipe 71, and U-shaped pipes 72 are connected to the bottom of both ends of the straight pipe 71. Both ends of the U-shaped pipe 72 are connected to the water supply pipeline 2. A flushing interface 711 is installed in the middle of the straight pipe 71, which is used for an external water pump to flush the middle of the water supply pipeline 2. A sealing cover 712 is installed at the flushing interface 711, and a sewage outlet 73 is installed at the bottom of one end of the U-shaped pipe 72 to facilitate the discharge of flushing sewage. A sealing plug 731 is installed at the sewage outlet 73.

[0027] Furthermore, valves 721 are installed at both ends of the U-shaped tube 72 to facilitate opening and closing of the U-shaped tube 72 .

[0028] Furthermore, a plurality of slow-flow baffles 12 are installed vertically at equal intervals inside the water storage tank 1. This design also helps to reduce water turbulence and mixing during water transportation, so that the cold water is more evenly distributed in the water storage tank.

[0029] Furthermore, a water level observation pipeline 11 is vertically installed on the outer side of the water storage tank 1 , and both ends of the water level observation pipeline 11 are connected to the water delivery pipeline 2 , so as to facilitate observation of the water level of the water storage tank 1 .

[0030] Furthermore, the water delivery pipeline 2 is a U-shaped structure, with both ends respectively connected to the left and right water storage tanks 1, which facilitates the connection inside the two water storage tanks 1 and ensures the same air pressure and water level.

[0031] When the high-efficiency segmented water cold storage and cooling device of the utility model is used, cold storage is first performed. When the power grid is in a low-power consumption period, the upper cold storage unit 3 starts to work and sends cooling water to the top of the water storage tank 1 through the water delivery pipeline 2. The cooling water flows from top to bottom in the water storage tank 1, and the slowing effect of the slow-flow baffle 12 prolongs the residence time of the cooling water in the water storage tank 1, thereby improving the cold storage efficiency. At the same time, the lower cold storage unit 4 also starts to work, and performs secondary cooling on the cooling water sent into the water storage tank 1 by the upper cold storage unit 3, thereby realizing a secondary cold storage operation. In this way, the temperature of the cooling water in the water storage tank 1 gradually decreases, preparing for the cooling demand during peak hours.

[0032] When the equipment needs to be cooled, first, the lower water inlet valve 61 is opened to send the cooling water at the bottom of the water storage tank 1 to the lower terminal device 6. The cooling water absorbs heat in the lower terminal device 6 to reduce the temperature of the equipment, and then is discharged through the lower water outlet valve 62. When the cooling demand of the lower terminal device 6 is met, the upper water inlet valve 51 can be opened to send the cooling water at the top of the water storage tank 1 to the upper terminal device 5. Similarly, the cooling water absorbs heat in the upper terminal device 5 to reduce the temperature of the equipment, and finally is discharged through the upper water outlet valve 52. Through this bottom-first and top-up cooling method, sequential cooling of multiple devices can be achieved to ensure the normal operation of the equipment and the comfort of the environment.

[0033] During long-term operation, impurities and dirt may accumulate in the water pipeline 2, causing the pipeline to be blocked. In order to solve this problem, the utility model installs an anti-blocking component 7 in the middle of the water pipeline 2. When the pipeline is found to be blocked, the sealing cover 712 of the anti-blocking component 7 can be opened, and the external water pump injects high-pressure water into the straight pipe 71 through the flushing interface 711. The high-pressure water enters the water pipeline 2 through the U-shaped tube 72 to flush the impurities and dirt in the pipeline. The sewage after flushing is discharged through the sewage outlet 73 at one end of the U-shaped tube 72. A sealing plug 731 is installed at the sewage outlet 73 to ensure that it remains sealed when sewage discharge is not required.

[0034] Finally, it should be noted that the upper cold storage unit 3, the lower cold storage unit 4, etc. in this embodiment, the electronic components in the above components are all universal standard parts or components known to technical personnel in this field, and their structures and principles can be known to technical personnel in this field through technical manuals or through conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires respectively. The specific connection means should refer to the working sequence between the electrical components in the above-mentioned working principle to complete the electrical connection, which are all well-known technologies in the field.
