At the same time, in order to ensure the power consumption of computers and environmental control systems, a huge power transmission and distribution system is also equipped. Therefore, the total energy consumption of the Internet data center is huge.

It is imperative to control the energy consumption of the Internet data center and improve the operating energy efficiency.

[0003] Currently, most common data centers use a 2N architecture redundant configuration power distribution system and a UPS system to power the liquid cooling device during a power outage.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] Below is the attached figure Figure 1 The technical solution of the utility model is further illustrated by specific implementation methods.

[0026] like Figure 1 As shown, a new type of liquid cooling distribution device for ensuring the operation of liquid cooling terminals in a power outage state includes a liquid storage tank 1 and a liquid cooling device 4;

[0027] The liquid storage tank 1 is filled with a first phase change medium, the first phase change medium has a liquid phase and a gas phase, and a power outage condition control pressure thermostat 11 is installed on the top of the liquid storage tank 1;

[0028] The input end and output end of the liquid cooling device 4 are respectively connected to the first delivery pipe 2 and the second delivery pipe 5. The end of the first delivery pipe 2 away from the liquid cooling device 4 is connected to the bottom end of the liquid storage tank 1, and the end of the second delivery pipe 5 away from the liquid cooling device 4 is connected to the top of the side wall of the liquid storage tank 1.

[0029] This solution uses a liquid storage tank 1, a power outage pressure control thermostat 11, a first delivery pipe 2, a second delivery pipe 5, and a liquid cooling device 4 in coordination. During a power outage, without the need for an additional power device, the first phase change medium in the liquid storage tank 1 can still flow between the liquid storage tank 1 and the liquid cooling device 4, thereby cooling the data center through the liquid cooling device 4.

[0030] Specifically, during a power outage, the liquid first phase change medium in the liquid cooling device 4 absorbs the heat emitted by the data center to cool the data center. The liquid first phase change medium absorbs heat and heats up before converting into the gaseous first phase change medium. The gaseous first phase change medium flows into the liquid storage tank 1 through the second delivery pipe 5, so that the pressure in the liquid storage tank 1 increases to force the liquid first phase change medium in the liquid storage tank 1 to flow into the liquid cooling device 4 through the first delivery pipe 2, thereby causing the first phase change medium to circulate between the liquid storage tank 1 and the liquid cooling device 4. During a power outage, the first phase change medium can circulate between the liquid storage tank 1 and the liquid cooling device 4 to cool the data center without the need for an additional power device, thereby ensuring the normal operation of the IT server. When the pressure in the liquid storage tank 1 is too high, the power outage condition pressure control thermostat 11 automatically controls the liquid storage tank 1 to deflate, thereby avoiding excessive pressure in the liquid storage tank 1.

[0031] like Figure 1 As shown, the first phase change medium is a refrigerant.

[0032] Specifically, the first phase change medium uses a refrigerant, which has excellent thermal conductivity. During the phase change process, it can quickly absorb or release a large amount of heat, thereby efficiently achieving cooling or heating, thereby better absorbing the heat emitted by the data center to cool the data center, and the discharged refrigerant has less impact on the environment, meeting environmental protection requirements.

[0033] like Figure 1 As shown, the power outage condition pressure control thermostat 11 is a safety valve.

[0034] Specifically, the safety valve has the function of automatic opening and closing, that is, it automatically opens when the pressure exceeds the set value, and automatically closes when the pressure drops below the set value, without the need for manual intervention. Therefore, when the pressure in the liquid storage tank 1 exceeds the set safety value, the safety valve will automatically open and release part or all of the gas to reduce the pressure in the liquid storage tank 1, preventing the liquid storage tank 1 from rupturing, exploding, and other dangerous situations due to overpressure, thereby automatically controlling the exhaust of the equipment in a power outage state. At the same time, the discharge of the gaseous refrigerant can appropriately reduce the temperature in the liquid storage tank 1, avoiding the liquid refrigerant in the liquid storage tank 1 from overheating and affecting the cooling effect on the data center.

[0035] like Figure 1 As shown, it also includes a cooling component 3, the cooling end of the cooling component 3 is inserted into the interior of the liquid storage tank 1, and the cooling end of the cooling component 3 cools the first phase change medium to convert the first phase change medium in gas phase into the first phase change medium in liquid phase.

[0036] Specifically, when there is electricity, the power supply device supplies power to the cooling component 3, and the first phase change medium in the liquid storage tank 1 can be cooled by the cooling component 3, so that the first phase change medium in the gas phase is converted into the first phase change medium in the liquid phase, thereby avoiding excessive pressure in the liquid storage tank 1 that causes the first phase change medium in the gas phase to be discharged, so that the first phase change medium can be recycled and resource waste can be reduced.

[0037] like Figure 1 As shown, the cooling assembly 3 includes a closed cooling tower 31 and a heat exchange pipe 32;

[0038] The closed cooling tower 31 is located outside the liquid storage tank 1, and the heat exchange tube 32 is arranged inside the liquid storage tank 1. The input end and the output end of the heat exchange tube 32 are respectively connected to the output end and the input end of the closed cooling tower 31. The heat exchange tube 32 is filled with a second phase change medium, and the second phase change medium has a liquid phase and a gas phase.

[0039] Specifically, when there is electricity, the second phase change medium in the heat exchange tube 32 flows into the closed cooling tower 31 through the closed cooling tower 31, and the closed cooling tower 31 cools the second phase change medium. The cooled second phase change medium flows back into the heat exchange tube 32, thereby ensuring that the second cooling medium in the heat exchange tube 32 has a lowered temperature to cool the first cooling medium in the liquid storage tank 1.

[0040] like Figure 1 As shown, the connections between the first delivery pipe 2 , the second delivery pipe 5 , the heat exchange pipe 32 and the liquid storage tank 1 are all provided with sealing members.

[0041] Specifically, the connection between the first delivery pipe 2, the second delivery pipe 5 and the heat exchange pipe 32 and the liquid storage tank 1 is sealed by a sealing member, so that the liquid storage tank 1 can be ensured to have good sealing performance.

[0042] like Figure 1 As shown, a pressure monitor 33 is installed at one end of the heat exchange tube 32 , and the pressure monitor 33 is located outside the liquid storage tank 1 .

[0043] Specifically, the pressure monitor 34 can monitor the pressure in the heat exchange tube 32 to ensure that the closed cooling tower 31 effectively cools the second phase change medium.

[0044] like Figure 1 As shown, the second phase change medium is a refrigerant.

[0045] Specifically, the second phase change medium uses a refrigerant, which can quickly absorb the heat of the first phase change medium to cool the first phase change medium.

[0046] like Figure 1As shown, the heat exchange tube 32 is in a disc shape.

[0047] Specifically, the disc-shaped heat exchange tube 32 can increase the contact area between the heat exchange tube 32 and the first phase change medium, so that the cooling component 3 has a good cooling effect.

[0048] Preferably, the amount of liquid refrigerant stored in the liquid storage tank 1 can enable the device to operate for 24 to 72 hours during a power outage, thereby ensuring that the server can be cooled normally without UPS power supply.

[0049] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
