Description

Technical Field

[0001] The present invention relates to the technical field of heat dissipation of submarine data centers, and in particular to a heat dissipation system for an ocean data center. Background Art

[0002] Currently, the heat dissipation technology of submarine data centers mainly relies on direct seawater cooling or indirect liquid cooling circulation systems in the pump area. The typical structure includes a server cluster in a sealed cabin, liquid cooling pipes in direct contact with the server heat source, a seawater circulation pump group and an external heat exchanger. The principle is to absorb the heat generated by the equipment through the internal circulating working fluid (such as water or fluorinated liquid), and then conduct heat with seawater through a heat exchanger made of titanium alloy or corrosion-resistant alloy, and finally the heat is carried away by the flow of seawater.

[0003] The main technical problems existing in the existing technology are as follows:

[0004] ① Seawater directly enters the cabin's cooling system, exposing it to long-term material corrosion risks. Although corrosion-resistant alloys are used, salt spray erosion in complex marine environments still needs to be considered;

[0005] ② The attachment of marine organisms and pressure fluctuations may still cause the performance of the heat exchanger to decline, requiring periodic maintenance;

[0006] ③ The current liquid cooling circulation system relies on high-power pumps to maintain the flow of working fluids, resulting in increased energy consumption. In particular, the pumping efficiency is reduced in the low-pressure environment of deep sea, affecting the overall energy efficiency ratio.

[0007] ④ The current passive heat pipe system has low heat dissipation efficiency, especially the heat dissipation efficiency at the condensation end in the marine environment needs to be improved, which will significantly improve the overall heat dissipation efficiency of the system. Summary of the Invention

[0008] The technical task of this invention is to provide a marine data center heat dissipation system to solve the problems existing in the existing submarine data center cooling system, such as high pump drive energy consumption, high corrosion risk of seawater entering the cooling system, and microorganisms adhering to the cooling fins affecting heat dissipation.

[0009] The technical task of the present invention is achieved in the following manner: a heat dissipation system for an ocean data center, comprising a submarine data center shelter, wherein a plurality of server cabinets are disposed within the submarine data center shelter. The server cabinets are provided with an evaporation end, and a refrigerant pipe is disposed at the outlet of the evaporation end. One end of the refrigerant pipe is connected to the evaporation end, and the other end of the refrigerant pipe is provided with a condensation end. The refrigerant is filled in the refrigerant pipe, and the refrigerant is driven by the refrigerant density difference and capillary force, without the need for a pump.

[0010] Among them, the condensing end adopts a turbine blade rotation module, which includes several turbine blades. The turbine blades rotate under the action of ocean tidal currents, intensifying the disturbance of seawater and destroying the thermal boundary layer, thereby achieving the effect of dissipating heat from the refrigerant and preventing microorganisms from attaching.

[0011] Preferably, a plurality of composite columns are symmetrically arranged on the submarine data center cabin, one end of the composite column is installed on the side wall of the submarine data center cabin, and the other end of the composite column is provided with a motor compartment, in which a generator is provided, and the generator is connected to a transmission line, which extends from the inside of the motor compartment to the inside of the composite column and passes through the inside of the composite column to the submarine data center cabin.

[0012] More preferably, a main shaft is provided at one end of the motor compartment, a rotary joint is provided on the main shaft, one end of the rotary joint is connected to the main shaft, a hub is provided at the other end of the rotary joint, and the turbine blades are symmetrically mounted on the hub. The rotary joint can both ensure the rotation of the hub and play a sealing role.

[0013] Preferably, the refrigerant pipeline includes a liquid phase pipeline and a gas phase pipeline;

[0014] A flat-plate heat pipe evaporator is used at the evaporation end. A gas phase outlet pipe is provided at one end of the flat-plate heat pipe evaporator. The gas phase outlet pipe is connected to the gas phase pipeline. The gas phase pipeline runs through the interior of the composite column and extends to the interior of the turbine blade. A liquid phase inlet pipe is provided at the other end of the flat-plate heat pipe evaporator. The liquid phase inlet pipe is connected to the liquid phase pipeline. The liquid phase pipeline is wrapped around the outer wall of the composite column and extends to the interior of the turbine blade.

[0015] Preferably, the flat heat pipe evaporator is directly connected to the internal chip of the server in the server cabinet or installed on the backplane of the server cabinet;

[0016] When the flat plate heat pipe evaporator is installed at the back plate of the server cabinet, air cooling is adopted inside the server, and the hot air exchanges heat with the flat plate heat pipe evaporator at the back plate of the server cabinet.

[0017] In addition, the evaporation end can also be built into the precision air conditioner in the cabin, and the evaporation end and the precision air conditioner can be used in conjunction.

[0018] Preferably, the flat-plate heat pipe evaporator includes a liquid storage chamber, a liquid wick and a steam chamber. One end of the liquid storage chamber is connected to the liquid phase inlet pipe, and the other end of the liquid storage chamber is connected to the liquid wick. The side of the liquid wick is attached to the back panel of the server chip or the server cabinet, and the steam chamber is connected to the gas phase outlet pipe.

[0019] More preferably, the liquid phase pipeline is wound in an S shape on the outer wall of the composite column, and the composite column is L-shaped.

[0020] Preferably, the submarine data center cabin is in a capsule shape, and a support base is provided at the bottom of the capsule-shaped submarine data center cabin, and the support base is trapezoidal.

[0021] Preferably, the turbine blades are arranged above the submarine data center cabin, so as to help gravity accelerate the return flow of the liquefied refrigerant;

[0022] The turbine blades adopt a bidirectional asymmetric airfoil. The relative thickness of the turbine blades with a bidirectional asymmetric airfoil is 15%-40%, and the relative thickness of the section of the turbine blade near the blade root is greater than the relative thickness of the section of the turbine blade near the blade tip; the maximum curvature of the turbine blade is located at 30%-60% of the chord length, and the height of the maximum curvature in the blade root area can reach 4%-8% of the chord length, and is reduced to 1%-3% in the blade tip area; the ratio of the chord length at the blade root to the hub diameter is 0.25-0.45; the torsion angle at the blade root is 15°-35°.

[0023] Preferably, the working process of the system is as follows: when the server is operating normally, the flat-plate heat pipe evaporator is heated, and the liquid absorption core absorbs the liquefied refrigerant from the liquid storage chamber. The liquefied refrigerant in the liquid absorption core is heated and evaporates to the steam chamber. The vaporized refrigerant inside the steam chamber enters the gas phase pipeline through the gas phase outlet pipe and is transported to the gas phase pipeline inside the turbine blade. The turbine blade rotates under the tidal action of the ocean current. While driving the generator in the motor compartment to generate electricity, the refrigerant in the gas phase pipeline inside the turbine blade is cooled and liquefied. The liquefied refrigerant enters the liquid phase pipeline. The liquid phase pipeline is wrapped around the outside of the composite column and is affected by seawater. The refrigerant is further cooled and liquefied during the reflux process, and finally returns to the liquid storage chamber of the flat-plate heat pipe evaporator through the liquid phase inlet pipe to complete the entire circuit.

[0024] The ocean data center heat dissipation system of the present invention has the following advantages:

[0025] (1) The composite column of the present invention integrates gas-phase pipelines and transmission lines, which are placed inside the composite column, while the liquid-phase pipeline is wrapped around the outside of the composite column. The transmission cable is connected to the generator in the motor compartment, and the gas-phase pipeline and liquid-phase pipeline are connected to the gas-phase pipeline and liquid-phase pipeline inside the turbine blade. The turbine blade serves as the condensing end, and the evaporating end uses a flat-plate heat pipe radiator, which is placed at the server in the submarine data center cabin. The radiator is driven by the refrigerant density difference and capillary force, without the need for a pump. The turbine blade not only generates electricity under the influence of ocean currents and tides, but also promotes heat dissipation due to its rotation and prevents the attachment of marine organisms.

[0026] (2) The present invention can utilize ocean tidal energy to provide power to the submarine data center while also utilizing ocean tidal energy to dissipate heat for the data center. This has the advantages of no energy consumption for heat dissipation, no seawater in the engine room, and prevention of marine organism attachment.

[0027] (3) The condensing end of the present invention is placed in seawater, thereby preventing seawater from entering the cabin and reducing the risk of seawater leakage;

[0028] (4) The condensing end of the present invention adopts the method of turbine blades, and the liquid phase pipeline is integrated inside the turbine blades. Due to the rotation of the turbine blades, the attachment of marine organisms is prevented or reduced. For example, the propeller of a ship is free of marine organisms, thereby improving the heat dissipation efficiency and power generation efficiency;

[0029] (5) The cooling systems of current marine data centers are all driven by pumps. The liquid phase pipes and turbine blades used in the present invention utilize seawater to dissipate heat, saving energy.

[0030] (6) The present invention adopts an innovative design that integrates the condensing end liquid phase pipeline and the gas phase pipeline into the turbine blade. Through the transmission of the turbine blade, the disturbance of the seawater is increased, which enhances heat exchange. The rapid rotation reduces the attachment of marine organisms and maintains continuous and efficient heat dissipation. In addition, the liquid phase pipeline is wrapped around the composite column, which is in direct contact with the low-temperature seawater, continuously cooling the working fluid, preventing heat leakage during the flow of the refrigerant, and ensuring pressure balance in the system (the gas phase pipeline is higher than the liquid phase pipeline), thereby improving the operating stability of the system and reducing the startup temperature.

[0031] (7) The turbine blades of the present invention are connected to the hub, which is connected to the main shaft of the motor compartment through a rotary joint (the rotary joint can ensure the rotation of the hub and the sealing of the internal working fluid). The hub rotates while the main shaft and the motor compartment do not rotate, achieving the purpose of power generation and efficient heat dissipation.

[0032] (8) This invention uses heat pipe technology to transfer heat from the server directly to the seawater outside the data center cabin, eliminating the risk of corrosion and leakage from seawater entering the cabin. Furthermore, due to the passive heat dissipation effect of the heat pipe, no additional pumping power is required, saving electricity. Furthermore, tidal turbine power generation technology is introduced into the submarine data center system to supplement the power supply for data center operation.

[0033] (9) The present invention combines heat pipe technology with tidal turbine power generation technology, integrating the outdoor condensing end with the turbine blades. The rotation of the turbine blades increases the disturbance of the seawater, destroying the temperature boundary layer and velocity boundary layer near the turbine blades. It also prevents the occurrence of modal boiling of the turbine blades at the condensing end, which could cause overheating, thereby improving the heat dissipation efficiency of the condensing end. In addition, the high rotation speed of the turbine blades prevents the attachment of marine organisms, which would greatly reduce the heat transfer efficiency of the condensing end.

[0034] (10) The present invention adopts a separate design for the gas phase pipeline and the liquid phase pipeline. The gas phase pipeline is placed inside the composite column, and the liquid phase pipeline is wrapped around the outside of the composite column. Because the liquid phase pipeline is in direct contact with seawater, the cooling effect of the reflux working fluid is further enhanced. The gas phase pipeline is not affected by seawater inside the column, thus forming a stable working fluid density difference in the circuit, improving the startup performance and operational stability of the passive heat dissipation system.

[0035] (11) The turbine blades at the condensing end of the heat dissipation system of the present invention are higher than the server cabinets in the submarine data center cabin, using gravity to accelerate liquid return;

[0036] (12) The turbine blades of the present invention rotate under the action of ocean tidal currents, serving not only as a driving generator but also as the condensing end of a heat dissipation system. Due to the high-speed rotation of the turbine blades, the attachment of marine organisms is prevented while enhancing the heat dissipation effect.

[0037] Therefore, the present invention has the characteristics of reasonable design, simple structure, easy processing, small size, convenient use, and multiple uses, and thus has good promotion and use value. BRIEF DESCRIPTION OF THE DRAWINGS
