[0024] This utility model provides a computer room cooling system. Figures 1 to 2 This invention provides a specific embodiment of a computer room cooling system.

[0025] like Figure 1 and Figure 2 As shown in the figure, this utility model embodiment provides a computer room cooling system 100, including a cooling pipe 1, a first cooling device 2, and a cold storage device 3. The cooling pipe 1 has a cooling end that can be connected to the computer room cooling equipment. The first cooling device 2 includes a first cooling port 21 and a second cooling port 22. The first cooling port 21 is connected to the cooling pipe 1. The cold storage device 3 includes a shell 31 and a water distribution assembly 32. The shell 31 is provided with a water storage chamber for storing liquid. The shell 31 is provided with an inlet 311 and an outlet 312. The water distribution assembly 32 includes a first water distribution part 321 located at the lower part of the water storage chamber. The inlet 311 and the outlet 312 are both connected to the water storage chamber through the first water distribution part 321. The inlet 311 is connected to the second cooling port 22, and the outlet 312 is connected to the cooling pipe 1.

[0026] In this utility model, the cooling pipe 1 has a cooling end that can be connected to the computer room cooling equipment. The first refrigeration device 2 includes a first cooling port 21 and a second cooling port 22. The first cooling port 21 is connected to the cooling pipe 1. The cold storage device 3 includes a shell 31 and a water distribution assembly 32. The shell 31 is provided with a water storage chamber for storing liquid. The shell 31 is provided with an inlet 311 and an outlet 312. The water distribution assembly 32 includes a first water distribution part 321 located at the lower part of the water storage chamber. The inlet 311 and the outlet 312 are both connected to the water storage chamber through the first water distribution part 321. The inlet 311 is connected to the second cooling port 22, and the outlet 312 is connected to the cooling pipe 1. Because the cooling demand of the computer room is higher during the day and lower at night, when electricity prices are lower at night, the third electrically controlled valve 6 is closed, while the first electrically controlled valve 4 and the second electrically controlled valve 5 are opened. The first refrigeration unit 2 supplies cooling to the cooling pipe 1 normally on one hand, and to the cold storage unit 3 on the other hand, to accumulate cooling capacity. At this time, the power consumption is higher. When electricity prices are higher during the day, the second electrically controlled valve 5 is closed, while the first electrically controlled valve 4 and the third electrically controlled valve 6 are opened. The first refrigeration unit 2 supplies cooling to the cooling pipe 1 normally, while the cold storage unit 3 provides auxiliary cooling to the cooling pipe 1 to meet the higher cooling demand of the computer room during the day. Although the total power consumption increases, the overall electricity cost is reduced due to the price difference between day and night.

[0027] To improve the cooling and cold storage efficiency of the computer room cooling system 100, in some embodiments, such as... Figure 1 As shown, both the first refrigeration device 2 and the cold storage device 3 are provided in multiples. Each first cooling port 21 is connected to the cooling pipe 1, and each inlet 311 of the cold storage device 3 is connected to the multiple second cooling ports 22. Furthermore, each outlet 312 of the cold storage device 3 is connected to the cooling pipe 1. By setting multiple first refrigeration devices 2 and multiple cold storage devices 3, the cold storage capacity of the computer room cooling system 100 is greatly improved. Multiple first refrigeration devices 2 and multiple cold storage devices 3 can simultaneously cool the computer room during the day, improving cooling efficiency. On the other hand, multiple first refrigeration devices 2 can be used simultaneously to cool a single cold storage device 3 at night, improving short-term cold storage efficiency to meet more practical needs.

[0028] To improve the cold storage and cooling efficiency of the cold storage device 3, in some embodiments, such as... Figure 2 As shown, the cold storage device 3 also includes a water distribution assembly 32, which includes a first water distribution section 321 located at the lower part of the water storage chamber. The water inlet 311 and the water outlet 312 are both connected to the water storage chamber through the first water distribution section 321. With this configuration, cold water is input to the cold storage device 3 through the second cooling port 22 of the first refrigeration device 2. Since the first water distribution part 321 is located at the lower part of the water storage chamber, and the water inlet 311 is connected to the water storage chamber through the first water distribution part 321, cold water is input from the lower part of the water storage chamber. Because when the water temperature is greater than 4°C, the lower the temperature, the greater the density, cold water will accumulate at the lower part of the water storage chamber, and hot water will accumulate at the upper part of the water storage chamber, achieving natural stratification of hot and cold water and avoiding heat exchange between hot and cold water, thereby improving the cold storage efficiency. At the same time, since the water outlet 312 is connected to the first water distribution part 321, the cold water at the lower part of the water storage chamber can be directly output to the cooling pipe 1, improving the cooling efficiency of the cold storage device 3.

[0029] It should be noted that the specific arrangement and structure of the first water distribution section 321 are not limited, as long as the first water distribution section 321 can output cold water to the bottom of the water storage chamber. For example, in some embodiments, such as Figure 2 As shown, the first water distribution section 321 is horizontally arranged, and multiple water distribution ports 3211 are spaced apart at the bottom of the first water distribution section 321. This arrangement allows cold water to be evenly distributed to various positions in the lower part of the water storage chamber through the multiple water distribution ports 3211, avoiding the cold water from being concentrated in one place and causing a large amount of cold water to rise under pressure and come into contact with the hot water above, resulting in heat exchange and reduced cold storage efficiency.

[0030] Since there is always some hot water in the water storage chamber, if the cold water at the bottom of the chamber does not exchange heat with the hot water at the top, the large temperature difference at different locations on the surface of the shell 31 may cause deformation of the shell 31. Therefore, in some embodiments, such as Figure 2 As shown, the water distribution assembly 32 further includes a second water distribution section 322 connected to the water inlet 311. The second water distribution section 322 is located above the water inlet 311 and at the upper part of the water storage chamber. This arrangement ensures that most of the cold water is still output from the first water distribution section 321 and collects at the lower part of the water storage chamber, while a small portion of the cold water is output from the second water distribution section 322 to exchange heat with the hot water, thereby lowering the temperature of the hot water.

[0031] Preferably, in some embodiments, such as Figure 2 As shown, the second water distribution section 322 is horizontally arranged, and multiple spray sections 323 are spaced apart on the top of the second water distribution section 322. This arrangement allows cold water to be evenly sprayed onto the upper part of the water storage chamber through the spray sections 323, increasing the contact area between cold and hot water, thereby accelerating the cooling rate and improving the cold storage efficiency.

[0032] During peak summer cooling season, relying solely on the first refrigeration unit 2 may not provide sufficient cooling capacity. Therefore, in some embodiments, such as... Figure 1 As shown, the computer room cooling system 100 also includes a second cooling device 7, which is connected to the cooling supply pipe 1. With this configuration, the second cooling device 7 does not need to supply cooling to the cold storage device 3; it directly outputs chilled water to the cooling supply pipe 1, ensuring that the computer room cooling system 100 can meet the demand during peak cooling periods.

[0033] To reduce electricity waste, in some embodiments, such as Figure 2 As shown, the cold storage device 3 also includes multiple temperature sensors 33 disposed within the water storage chamber. These temperature sensors 33 are spaced apart along the height of the housing 31. Both the multiple temperature sensors 33 and the first refrigeration device 2 are electrically connected to a controller. When a temperature sensor 33 detects that the water temperature at various points within the water storage chamber has reached the required temperature, it sends a signal to the controller. The controller then controls the second electrically controlled valve 5 to close, and the first refrigeration device 2 stops outputting cold water to the cold storage device 3.

[0034] The cold storage device 3 accumulates scale inside after prolonged use and requires regular cleaning. Therefore, in some embodiments, such as... Figure 2As shown, the cold storage device 3 also includes a drain pipe 34 located at the bottom of the housing 31, which is connected to the water storage chamber via a valve. The drain pipe 34 drains the liquid from the housing 31 to facilitate subsequent cleaning of the interior of the housing 31.

[0035] To prevent overflow due to excessive cold water input, in some embodiments, such as Figure 2 As shown, the cold storage device 3 also includes an overflow pipe 35 located on the side of the housing 31, which is connected to the drain pipe 34. When the liquid level is higher than the overflow pipe 35, excess water will be discharged from the overflow pipe 35 to the drain pipe 34.

[0036] In some embodiments, such as Figure 2 As shown, the cold storage device 3 also includes a fire pipe 36 located on the side of the housing 31, which is connected to the drain pipe 34. In an emergency, firefighters can draw water from the housing 31 through the fire pipe 36 to carry out firefighting operations.

[0037] When the liquid level in the housing 31 is too low, water needs to be added to ensure the cold storage performance of the cold storage device 3. In some embodiments, such as... Figure 2 As shown, the computer room cooling system 100 also includes a water supply pipe 8, which is connected to the water storage chamber of the housing 31. This configuration allows water to be supplied to the water storage chamber of the housing 31 via the water supply pipe 8.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
