Description

TECHNICAL FIELD

[0001] The application relates to a submarine heat dissipation technology field, in particular to a wind-liquid isogenic heat dissipation system suitable for a submarine data center. BACKGROUND

[0002] At present, the submarine data center heat dissipation technology mainly depends on the seawater direct cooling or indirect liquid cooling circulation system of the pump area. The typical structure comprises a server cluster in a sealed cabin, a liquid cooling pipeline in direct contact with the server heat source, a seawater circulating pump group and an external heat exchanger. The principle is that the internal circulating working medium (such as water or fluorinated liquid) absorbs the heat generated by the equipment, and then the heat exchanger made of titanium alloy or corrosion-resistant alloy material conducts heat with seawater, and finally the seawater flow takes away the heat.

[0003] The main problem existing in the prior art is that the data center is directly placed in the marine environment, which faces the risk of material corrosion. Although corrosion-resistant alloys and other sealing measures are adopted, salt spray corrosion, microbial attachment and pressure fluctuation in the complex marine environment may still cause the submarine data center shelter to leak, damage the server and other computing power equipment, and finally cause serious loss. SUMMARY

[0004] When the data center shelter is placed in the submarine, due to the influence of the complex environmental factors such as high corrosion in the sea and ocean current impact, the shelter is prone to leakage crisis, thereby damaging the computing power equipment and causing property loss. In view of the above situation, the application provides a wind-liquid isogenic heat dissipation system suitable for a submarine data center to ensure the normal operation of the server group and the cooling system of the data center shelter when leakage occurs.

[0005] The technical scheme adopted to solve the above technical problems of the wind-liquid isogenic heat dissipation system suitable for the submarine data center is as follows:

[0016] The control valve three controls the on-off of the oil-water separator and the high-pressure interlayer chamber;

[0017] The control valve five and the control valve four are connected in series, and the control valve five is arranged at the outlet end of the submarine condensing chamber, and the control valve four is arranged at the inlet end of the gas-liquid separator.

[0018] Further, the high-temperature ring network is connected with a pressure sensor three and a pressure relief valve. The pressure sensor three monitors the pressure of the high-temperature ring network in real time, and the pressure relief valve is opened or closed to stabilize the pressure of the gaseous refrigerant in the high-temperature ring network.

[0019] Further, when the submarine condensing chamber is in a normal working state without leakage, the control valve one, the control valve three, the control valve four and the control valve five are all in an open state. The submarine condensing chamber is directly in contact with seawater outside, and the seawater cools the high-pressure gaseous refrigerant in the submarine condensing chamber to condense it into high-pressure liquid refrigerant.

[0029] Attachment Figure 1 Schematic diagram of the system architecture of an embodiment of the present invention. DETAILED DESCRIPTION

[0030] In order to make the technical solution, the technical problems solved and the technical effects of the present invention more clear, the technical solution of the present invention is clearly and completely described below in conjunction with specific embodiments.

[0031] Example:

[0032] Combined with attachment Figure 1 This embodiment proposes a leak-proof air-liquid homogenous heat dissipation system suitable for submarine data centers, the structure of which includes a high-pressure interlayer chamber, a submarine condensation chamber, a hydraulic shelter, and a computing power shelter;

[0033] The high-pressure interlayer chamber is filled with high-pressure gaseous refrigerant participating in the cycle, and a pressure sensor 2 and a valve control system are installed outside the high-pressure interlayer chamber;

[0034] The outer side of the submarine condensation chamber is in direct contact with seawater, a pressure sensor is provided outside the submarine condensation chamber, and the submarine condensation chamber is connected to the high-pressure gaseous refrigerant in the high-pressure interlayer chamber;

[0035] The water conservancy shelter is equipped with a pressure-stabilizing gas tank, a gas-liquid separator, a fluorine pump, an oil-water separator, a compressor, and nested low-temperature and high-temperature ring networks. The pressure-stabilizing gas tank is connected to the high-pressure interlayer chamber. The inlet of the gas-liquid separator is connected to the high-pressure interlayer chamber and the submarine condensation chamber through a valve control system. The outlet of the gas-liquid separator is directly connected to the low-temperature ring network or connected to the low-temperature ring network through a fluorine pump. The high-temperature ring network is directly connected to the high-pressure interlayer chamber through the oil-water separator or connected to the oil-water separator through a compressor and then to the high-pressure interlayer chamber.

[0036] The computing power cabin includes a server group, a liquid-cooled terminal CDU, and an air-cooled terminal air conditioner. The server group is connected to the liquid-cooled terminal CDU through a liquid cooling pipeline, transferring heat to the refrigerant in the liquid-cooled terminal CDU. The liquid-cooled terminal CDU and the air-cooled terminal air conditioner are connected to the low-temperature ring network to obtain liquid refrigerant, and are connected to the high-temperature ring network through a one-way valve to discharge the gaseous refrigerant after absorbing heat.

[0037] The low-temperature ring network involved in this embodiment is a closed circulation pipeline for transporting liquid refrigerant, and the liquid refrigerant circulates inside it after condensation / cooling. One end of the pipeline is directly connected to the gas-liquid separator or connected to the gas-liquid separator through a fluorine pump, and the other end is connected to the inlet of the liquid-cooled terminal CDU and the air-cooled terminal air conditioner, respectively, so as to transport the liquid refrigerant to the liquid-cooled terminal CDU and the air-cooled terminal air conditioner.

[0038] The high-temperature ring network relates to a closed cycle pipeline for conveying gaseous refrigerant, and the gaseous refrigerant in the pipeline absorbs heat. One end of the pipeline is connected to the outlet of the liquid-cooled terminal CDU and the air-cooled terminal air conditioner through a one-way valve respectively to receive the gaseous refrigerant discharged by the liquid-cooled terminal CDU and the air-cooled terminal air conditioner. The other end of the pipeline is connected to the high-pressure interlayer chamber through an oil-water separator or connected to the high-pressure interlayer chamber through a compressor and an oil-water separator in sequence, so as to convey the gaseous refrigerant back to the high-pressure interlayer chamber.

[0039] The valve control system includes a control valve one, a control valve two, a control valve three, a control valve four and a control valve five.

[0040] The control valve one controls the high-pressure interlayer chamber to convey high-pressure gaseous refrigerant to the submarine condensing chamber.

[0041] The control valve two is connected between the control valve five and the control valve four to provide a bypass path of the high-pressure interlayer chamber to the gas-liquid separator, and change the flow direction of the high-pressure gaseous refrigerant.

[0042] The control valve three controls the on-off connection between the oil-water separator and the high-pressure interlayer chamber.

[0043] The control valve five and the control valve four are connected in series, and the control valve five is arranged at the outlet end of the submarine condensing chamber, and the control valve four is arranged at the inlet end of the gas-liquid separator.

[0044] The high-temperature ring network is connected with a pressure sensor three and a pressure relief valve. The pressure sensor three monitors the pressure of the high-temperature ring network in real time, and the pressure relief valve is opened and closed to stabilize the pressure of the gaseous refrigerant in the high-temperature ring network.

[0045] When the submarine condensing chamber does not leak and is in a normal working state, the control valve one, the control valve three, the control valve four and the control valve five are all in an open state. The submarine condensing chamber is directly in contact with seawater outside, and the seawater cools the high-pressure gaseous refrigerant connected to the submarine condensing chamber to condense it into high-pressure liquid refrigerant. The high-pressure liquid refrigerant output by the submarine condensing chamber enters the gas-liquid separator through the control valve five and the control valve four, and then enters the low-temperature ring network through the bypass 1 or the fluorine pump. The liquid-cooled terminal CDU and the air-cooled terminal air conditioner obtain liquid refrigerant from the low-temperature ring network, and the liquid refrigerant is vaporized into gaseous refrigerant after absorbing heat, and then discharged to the high-temperature ring network through a one-way valve. The pressure sensor three monitors the pressure of the high-temperature ring network in real time, and the pressure relief valve is opened and closed to stabilize the pressure of the gaseous refrigerant in the high-temperature ring network. The gaseous refrigerant in the high-temperature ring network returns to the high-pressure interlayer chamber in sequence through the bypass 2, the oil-water separator and the leakage valve three, or returns to the high-pressure interlayer chamber in sequence through the compressor, the oil-water separator and the leakage valve three, to form a complete cycle.

[0046] When a leak occurs in the submarine condensing chamber, the pressure sensor detects the pressure fluctuation around the submarine condensing chamber and transmits a signal to the controller. The controller then closes control valve one and control valve five, and opens control valve two, so that the submarine condensing chamber forms an isolated space. At this time, the outside of the submarine condensing chamber is still in direct contact with seawater, and the isolated space inside the submarine condensing chamber maintains a low temperature state due to continuous cooling by seawater. The high-pressure interlayer chamber is connected to the submarine condensing chamber by a pipeline with heat exchange function (the pipeline can transfer cold through heat conduction). The cold is continuously transferred to the inside of the high-pressure interlayer chamber through the pipeline, so that the high-pressure interlayer chamber has a low-temperature environment required for condensation of refrigerant, and is then converted into a temporary condensing chamber. The high-pressure gaseous refrigerant in the temporary condensing chamber releases heat and liquefies into high-pressure liquid refrigerant under the action of cold, and then enters the gas-liquid separator through the opened control valve two and control valve four. After gas-liquid separation, the liquid refrigerant enters the low-temperature ring network through bypass 1 or the fluorine pump. The liquid cooling terminal CDU and the air cooling terminal air conditioner obtain liquid refrigerant from the low-temperature ring network, gasify into gaseous refrigerant after absorbing heat, and discharge to the high-temperature ring network through the one-way valve. The pressure sensor three monitors the pressure of the high-temperature ring network in real time, and opens and closes the pressure relief valve to stabilize the pressure of the gaseous refrigerant in the high-temperature ring network. The gaseous refrigerant in the high-temperature ring network enters the high-pressure interlayer chamber through bypass 2, oil-water separator and control valve three in sequence, or enters the high-pressure interlayer chamber through compressor, oil-water separator and control valve three in sequence, to form a complete cycle.

[0047] In order to better control the working state of the fluorine pump and the compressor, a temperature sensor is arranged outside the submarine condensing chamber. The temperature sensor monitors the seawater temperature outside the submarine condensing chamber in real time, and based on the monitored seawater temperature, the fluorine pump or the compressor is opened alone, or the fluorine pump and the compressor are opened at the same time.

[0048] The low temperature threshold and the high temperature threshold of seawater are set in advance;

[0049] When the seawater temperature monitored by the temperature sensor is lower than the low temperature threshold, the fluorine pump is opened by the controller. The high-pressure liquid refrigerant output by the submarine condensing chamber enters the gas-liquid separator through control valve five and control valve four, and then enters the low-temperature ring network through the fluorine pump;

[0050] When the seawater temperature monitored by the temperature sensor is higher than the high temperature threshold, the compressor is opened by the controller. The gaseous refrigerant in the high-temperature ring network enters the high-pressure interlayer chamber through the compressor, the oil-water separator and the leak valve three in sequence;

[0051] When the seawater temperature monitored by the temperature sensor is between the low temperature threshold and the high temperature threshold, the opening of the fluorine pump and the compressor is simultaneously controlled by the controller, at this time: the high-pressure liquid refrigerant output by the submarine condensing chamber enters the gas-liquid separator after the control valve five and the control valve four, and then enters the low-temperature ring network through the fluorine pump; the liquid cooling terminal CDU and the air-cooled terminal air conditioner obtain liquid refrigerant from the low-temperature ring network, and after absorbing heat, the gaseous refrigerant is discharged to the high-temperature ring network through the one-way valve; the pressure sensor three monitors the pressure of the high-temperature ring network in real time, and opens and closes the pressure relief valve to ensure the stable pressure of the gaseous refrigerant in the high-temperature ring network; the gaseous refrigerant in the high-temperature ring network returns to the high-pressure interlayer chamber in turn through the compressor, the oil-water separator and the leakage valve three.

[0052] It should be noted that the "high pressure" in the embodiment refers to the pressure state of the fluid (such as refrigerant) in a specific circulation stage (such as high-temperature ring network, high-pressure interlayer chamber), which is higher than the fluid pressure in other stages (such as low-temperature ring network) in the same circulation system, and is sufficient to drive the fluid to flow in a one-way manner in the preset pipeline (such as overcoming pipeline resistance, maintaining circulation power). Its pressure characteristics are reflected by the pressure difference in the system, which is specifically manifested as: enabling the fluid to enter the high-temperature ring network through the one-way valve after heat absorption and vaporization, and realizing pressure regulation through the preset threshold (such as automatically opening when the pressure exceeds the system safety threshold) of the pressure relief valve, thereby forming a circulation pressure difference with the "low pressure" state, and ensuring the stable operation of the system.

[0053] As can be seen from the above, the anti-leakage air-liquid homogeneous heat dissipation system suitable for submarine data center can provide heat dissipation service for the server group in the normal operation mode when no leakage occurs, and can continue to provide heat dissipation service for the server group by changing the on-off state of the control valve through the valve control system when leakage occurs.

[0054] Based on the above specific embodiments of the present application, any improvements and modifications made by those skilled in the art without departing from the principles of the present application shall fall within the scope of the patent protection of the present application.
