Description

Technical Field

[0001] The present application relates to the field of liquid cooling, and particularly to a two-phase liquid cooling system with a voltage stabilizing device. Background Art

[0002] A two-phase liquid cooling cabinet is a device that uses two-phase immersion liquid cooling technology.

[0003] Its working principle is as follows: During the circulating heat dissipation process, the coolant continuously undergoes a phase change process from liquid to gas and then back to liquid. The IT equipment is completely immersed in a sealed tank filled with a low-boiling coolant. The heat generated by the equipment is absorbed by the coolant. After absorbing heat, the temperature of the coolant rises to the boiling point and starts to boil, changing from liquid to gas, generating a large amount of steam. After the steam rises to the gas phase area above the liquid surface and contacts the water-cooled condenser, the heat is absorbed by the condenser, and the coolant condenses into liquid and falls back into the container in the form of liquid droplets for recycling. The heated cooling water in the condenser is then discharged of heat through the circulating cooling water system.

[0004] Traditional condensers are mainly heat exchange coils. Due to the long and winding path, the heat dissipation efficiency of the later heat exchange tubes is lower. As the condensed water in the condenser continuously exchanges heat with the rising gaseous condensate during the flow along the pipeline, the heat exchange efficiency of the later section of the heat exchange tube is low. Currently, the heat exchange tubes mainly use round tubes, which have a small contact area, resulting in low heat exchange efficiency. Low heat dissipation efficiency will cause the internal air pressure of the liquid cooling cabinet to increase. Summary of the Invention

[0005] To solve the above problems, the present application provides a two-phase liquid cooling system with a voltage stabilizing device.

[0006] The two-phase liquid cooling system with a voltage stabilizing device provided by the present application adopts the following technical solutions:

[0007] A two-phase liquid cooling system with a voltage stabilizing device, characterized by comprising:

[0008] A liquid cooling box for placing servers and two-phase coolant;

[0009] A voltage stabilizing box communicated with the liquid cooling box through an air outlet pipe and a liquid return pipe;

[0010] Wherein the liquid cooling box includes a box body and a box cover. The box body is hermetically connected to the box cover. A condensation component is provided at the box cover. The condensation component includes an inlet pipe, an outlet pipe, and a shunt pipe. Both ends of the shunt pipe are respectively connected to the inlet pipe and the outlet pipe. The cross-sections of the inlet pipe, the outlet pipe, and the shunt pipe are all rhombic.

[0011] By adopting the above technical solution, in this solution, the cross-section of the condensation component is set to be diamond-shaped, so as to increase the heat exchange area with the steam. In addition, the total-subtotal pipeline layout method is adopted, and the cooling water can be quickly distributed to the shunt pipes through the inlet pipe, and then the high-temperature cooling water in the shunt pipes after heat absorption is gathered in the outlet pipe and discharged. Since the shunt pipe is a straight pipe with a short path, the heat exchange efficiency is high, and it also avoids the need to set a high-power pump like the heat exchange coil (the heat exchange coil has many bends and large power loss, so the pump power needs to be high).

[0012] Optionally, the box cover includes two cover bodies symmetrically arranged. An accommodating cavity is recessed downward inside the cover body, and at least part of the condensation component is located in the accommodating cavity.

[0013] By adopting the above technical solution, the two cover bodies facilitate the opening of the box cover. The condensation component is integrally connected with the box cover. In this way, only by opening the cover body can the server in the liquid cooling box be hoisted and repaired.

[0014] Optionally, isosceles triangular blocking edges are fixedly formed at both ends of the box body. One side of each cover body is hinged to the box body, and the opposite sides of the two cover bodies are in contact with each other, and the two cover bodies are simultaneously in contact with the waists of the isosceles triangular blocking edges.

[0015] By adopting the above technical solution, due to the existence of the isosceles triangular blocking edges, the cover bodies are all set to be inclined, which can increase the length of the shunt pipes in the heat exchange component and further increase the heat exchange area.

[0016] Optionally, an exhaust port is opened on the pressure stabilizing box, and the exhaust port is communicated with the external air. An elastic container is connected to each exhaust port, and the elastic container is hermetically connected to the exhaust port, and the exhaust ports are all directed towards the contact portion of the two cover bodies.

[0017] By adopting the above technical solution, when the internal air pressure of the liquid cooling box increases, the steam will enter the pressure stabilizing box and compress the elastic container to complete pressure relief. The elastic container is in a natural state when the steam does not enter, and the air inside the elastic container is squeezed out when it is compressed. And since the exhaust ports are aligned with the contact portion of the two cover bodies, when the elastic container is compressed, the air flows towards the junction of the two cover bodies, and after being guided by the inclined surface of the cover body, it flows to both sides, thereby dissipating heat from the cover body; this method is beneficial to reducing the influence of the ambient temperature on heat dissipation.

[0018] Optionally, the pressure stabilizing box is located directly above the liquid cooling box, a hydraulic cylinder for driving the pressure stabilizing box to lift is fixed on the liquid cooling box, and an extrusion portion for abutting against the upper surface of the box cover is fixed at the bottom of the pressure stabilizing box.

[0019] By adopting the above technical solution, since the cover body is inclined, excessive air pressure in the liquid cooling box can easily cause the cover body to open. The compression cylinder is used to drive the pressure stabilizing box, and the pressure stabilizing box drives the extrusion part for hydraulic locking, ensuring reliable sealing. At the same time, the setting of the hydraulic cylinder also facilitates opening the cover body after the pressure stabilizing box moves.

[0020] Optionally, the pressure stabilizing box is provided with exhaust ports, the exhaust ports are communicated with the external air, and each exhaust port is connected with an elastic container. The elastic container is hermetically connected to the exhaust port, and the exhaust ports are respectively located on both sides of the pressure stabilizing box.

[0021] By adopting the above technical solution, this arrangement is beneficial to saving space and setting more elastic containers.

[0022] Optionally, an auxiliary member is arranged in the elastic container, and the auxiliary member is made of a material that can be compressed and reduced and can recover.

[0023] By adopting the above technical solution, for elastic containers with a relatively large volume, it is not easy to recover by relying on their own material properties after being compressed. Therefore, an auxiliary member needs to be arranged in the elastic container.

[0024] Optionally, one-way valves are arranged on both the air outlet pipe and the liquid return pipe. The flow direction of the one-way valve on the air outlet pipe is from the liquid cooling box to the pressure stabilizing box, and the flow direction of the one-way valve on the liquid return pipe is from the pressure stabilizing box to the liquid cooling box.

[0025] By adopting the above technical solution, the setting of the one-way valve enables the steam to only enter the pressure stabilizing box from the air outlet pipe, and the coolant can only flow back from the liquid return pipe.

[0026] Optionally, a safety exhaust valve is arranged on the liquid cooling box.

[0027] The function of the safety exhaust valve is that when the pressure in the liquid cooling box is too high and the pressure regulation cannot be achieved through the pressure stabilizing device, the safety exhaust valve opens.

[0028] Optionally, a cooler is arranged on the pressure stabilizing box, and the cooler is used to accelerate the liquefaction of the gas entering the pressure stabilizing box.

[0029] The presence of the cooler can accelerate the liquefaction of the gas in the pressure stabilizing box, enabling it to quickly flow back into the liquid cooling box, and is also beneficial to quickly reducing the pressure.

[0030] Optionally, for two adjacent diamond-shaped flow dividing pipes, 0≤s / d<2.5, where d refers to the dimension of the diamond-shaped flow dividing pipe along the y direction, and s refers to the distance between two adjacent diamond-shaped flow dividing pipes; s / d = 0 means that the two diamond-shaped flow dividing pipes s are in contact or have no distance.

[0031] The flow pattern of the double diamond prism is more complex. Especially when the spacing ratio is low (0 ≤ s / d < 2.5), the geometry causes stronger gap flow and vortex interaction, generating various vortices, which can improve the heat transfer effect. The unique flow characteristics of the diamond tube (such as enhanced turbulent mixing) can enhance the heat transfer efficiency.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. This application improves the heat exchange tube structure of the condensation component, changing from the traditional coiled tube to the form of an inlet tube, an outlet tube, and a shunt tube, and designing the pipe cross-section as a diamond shape, which can generate stronger gap flow and vortex interaction to improve the heat exchange efficiency and has a better pressure stabilization effect;

[0034] 2. Use the elastic container in the pressure stabilization box to adjust the pressure, thereby balancing the pressure in the liquid cooling box;

[0035] 3. Set a safety exhaust valve to ensure the safety of the system. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The following will further describe this application in detail with reference to the Figures 1-5 drawings.

[0044] Example 1: The embodiment of the present application discloses a two-phase liquid cooling system with a voltage stabilizing device, including a liquid cooling box 1 and a voltage stabilizing box 2. A support block 3 is fixed at the bottom inside the voltage stabilizing box 2. The support block 3 is generally a porous support block 3, and the server 4 can be placed on the support block 3 so that the bottom of the server 4 can also be in contact with the coolant.

[0045] The liquid cooling box 1 is used to place the server 4 and the two-phase coolant; the voltage stabilizing box 2 is communicated with the liquid cooling box 1 through an air outlet pipe 5 and a liquid return pipe 6; one-way valves are arranged on both the air outlet pipe 5 and the liquid return pipe 6. The flow direction of the one-way valve on the air outlet pipe 5 is from the liquid cooling box 1 to the voltage stabilizing box 2, and the flow direction of the one-way valve on the liquid return pipe 6 is from the voltage stabilizing box 2 to the liquid cooling box 1. The setting of the one-way valve enables the steam to only enter the voltage stabilizing box 2 from the air outlet pipe 5, and the coolant to only flow back from the liquid return pipe 6.

[0046] A liquid replenishing box 22 can also be arranged between the voltage stabilizing box 2 and the liquid cooling box 1. In this way, the liquid return pipe 6 is divided into an inlet section and an outlet section. The inlet section is communicated with the liquid replenishing box 22 and the voltage stabilizing box 2, and the outlet section is communicated with the liquid replenishing box 22 and the liquid cooling box 1. A liquid level sensor 23 is arranged in the liquid cooling box 1, and a liquid replenishing pump 24 is arranged in the liquid replenishing box 22. The two-phase coolant in the liquid replenishing box 22 is replenished into the liquid cooling box 1 through the liquid replenishing pump 24. When the liquid level sensor 23 detects that the liquid level is lower than the set value, the liquid replenishing pump 24 is turned on, and when the liquid level sensor 23 detects that the liquid level is higher than the set value, the liquid replenishing pump 24 is turned off.

[0047] The liquid cooling box 1 includes a box body 7 and a box cover 8. The box body 7 is hermetically connected to the box cover 8. A condensation assembly 9 is arranged at the box cover 8. The condensation assembly 9 includes an inlet pipe 10, an outlet pipe 11 and a shunt pipe 12. Both ends of the shunt pipe 12 are respectively connected to the inlet pipe 10 and the outlet pipe 11. The cross sections of the inlet pipe 10, the outlet pipe 11 and the shunt pipe 12 are all rhombuses. For adjacent two rhombic shunt pipes, 0≤s / d<2.5, where d refers to the dimension of the rhombic shunt pipe along the y direction, and s refers to the distance between adjacent two rhombic shunt pipes; s / d = 0 means that the two rhombic shunt pipes s are in contact or have no distance.

[0048] The flow pattern of the double-rhombic prism is more complex. Especially when the spacing ratio is low (0≤s / d<2.5), the geometry leads to stronger gap flow and vortex interaction, generating various vortices, which can improve the heat exchange effect in this way. The unique flow characteristics of the rhombic pipe (such as enhanced turbulent mixing) can improve the heat transfer efficiency. The main flow directions in the horizontal and vertical directions are x and y respectively, which can be understood as the horizontal and vertical directions of the liquid cooling box. Preferably, when arranged in the x direction, 0.5<s / d<1.0, the gap flow triggers Karman vortices and fluctuations, and the bistable phenomenon is significant. Preferably, in the y direction, 1.1<s / d<2.3: the shear layer alternately adheres to the downstream rhombic prism, forming intermittent vortex shedding.

[0049] In this solution, the cross-section of the components of the condensation assembly 9 is set to a rhombus, which can increase the heat exchange area with the steam. In addition, a total - sub - total pipeline layout method is adopted, and the cooling water can be quickly distributed to the shunt pipes 12 through the inlet pipe 10, and then the high - temperature cooling water in the shunt pipes 12 after heat absorption is converged in the outlet pipe 11 and discharged. Since the shunt pipes 12 are straight pipes with a short path, the heat exchange efficiency is high, and it also avoids the need to set a high - power pump like the heat exchange coil (the heat exchange coil has many bends and large power loss, so a high - power pump is required).

[0050] The box cover 8 is generally a flat cover. In this application, the box cover 8 is set into two symmetrical cover bodies 13. An accommodation cavity is formed by concave - inward below the cover body 13, and at least part of the condensation assembly 9 is located in the accommodation cavity. Multiple groups of the condensation assembly 9 can be set as needed. When multiple groups of the condensation assembly 9 are arranged, they are distributed vertically, and the shunt pipes 12 of two adjacent groups of the condensation assembly 9 are horizontally staggered, so that the contact surface between the steam and the condensation assembly 9 is larger. The two cover bodies 13 facilitate the opening of the box cover 8. The condensation assembly 9 is integrally connected with the box cover 8. In this way, only by opening the cover body 13, the server 4 in the liquid - cooled box 1 can be hoisted and maintained. In the traditional method, the condensation assembly 9 is installed on the condensation box, so after the cover is opened, the condensation assembly 9 needs to be disassembled first before the server 4 can be maintained.

[0051] An isosceles - triangle baffle 14 is fixedly formed at both ends of the box body 7. One side of each of the cover bodies 13 is hinged to the box body 7. The opposite sides of the two cover bodies 13 are in contact with each other, and the two cover bodies 13 are simultaneously in contact with the waists of the isosceles - triangle baffle 14. Sealing strips are arranged on the surfaces where the two cover bodies 13 are in contact with each other, and sealing strips are also adhered to the waists of the isosceles - triangle baffle 14. By squeezing the sealing strips, the reliability of the sealing of the cover body 13 is ensured. Due to the existence of the isosceles - triangle baffle 14, the cover bodies 13 are both set to be inclined, which can increase the length of the shunt pipes 12 in the heat exchange assembly and further increase the heat exchange area.

[0052] An exhaust port 15 is opened on the pressure - stabilizing box 2. The exhaust port 15 is communicated with the external air. An elastic container 16 is connected to each exhaust port 15. The elastic container 16 is hermetically connected to the exhaust port 15. The exhaust ports 15 are respectively located on both sides of the pressure - stabilizing box 2.

[0053] Among them, the elastic container 16 can be made of materials such as silica gel and rubber as a whole, which can be imagined as a balloon, or it can be made of local hard materials and part of silica gel, such as the structure of an accordion. In order to facilitate the later recovery of the elastic container 16, an auxiliary member 17 is provided inside the elastic container 16, and the auxiliary member 17 is made of a material that can be compressed and reduced and can recover. The auxiliary member 17 can be a filler made of materials such as cotton and down, or a hollow skeleton sphere made of rubber. Specifically, the elastic container 16 is generally in a sector-like structure when not under pressure, and the auxiliary member 17 is located at the middle position of the elastic container 16.

[0054] A safety exhaust valve 21 is provided on the liquid cooling box 1. The function of the safety exhaust valve 21 is that when the pressure in the liquid cooling box 1 is too high and the pressure regulation cannot be achieved through the pressure stabilizing box 2, the safety exhaust valve 21 opens.

[0055] A cooler 18 is provided on the pressure stabilizing box 2, and the cooler 18 is used to accelerate the liquefaction of the gas entering the pressure stabilizing box 2. The presence of the cooler 18 can accelerate the liquefaction of the gas in the pressure stabilizing box 2, enabling it to quickly flow back into the liquid cooling box 1, and is also beneficial for quickly reducing the pressure. The cooler 18 can be one of a liquid cooling plate, a cold row, and a fan.

[0056] Among them, the inlet pipe 10 and the shunt pipe 12 of the condensation assembly 9 are generally externally connected to the pipes of a water cooling tower, and when the cooler 18 can be a liquid cooling plate, the pipes of the water cooling tower also need to be connected. The water cooling tower is used to cool down the cooled water after heat absorption.

[0057] Among them, coolant such as silicate esters, aromatic substances, silicone, aliphatic compounds, and fluorocarbon compounds can all be applied. Among them, fluorocarbon compounds have the best comprehensive performance and are more commonly used. For example, Fluoriner electronic fluorinated liquid and Novec electronic engineering liquid of 3M Company have excellent thermal stability and chemical stability, are odorless, non-flammable, non-oil-based, low-toxicity, and non-corrosive.

[0058] The implementation principle of a two-phase liquid cooling system with a pressure stabilizing device in an embodiment of the present application is as follows: When the coolant in the liquid cooling box 1 absorbs the heat dissipated by the server 4 and forms steam, the steam condenses and flows back after contacting the condensation assembly 9. When the heat of the server 4 is excessive and the steam condensation speed is too late, the steam will enter the pressure stabilizing box 2 from the air outlet pipe 5. At this time, the elastic container 16 will be compressed, and the elastic container 16 is compressed; when the steam exceeds the limit value and causes the pressure in the liquid cooling box 1 to be too high, the safety exhaust valve 21 opens.

[0059] Embodiment 2: A two-phase liquid cooling system with a voltage stabilizing device, which is different from Embodiment 1 in that: an exhaust port 15 is provided on the voltage stabilizing tank 2, and the exhaust port 15 is communicated with the external air. An elastic container 16 is connected to each exhaust port 15, and the elastic container 16 is hermetically connected to the exhaust port 15. The exhaust ports 15 are all oriented towards the abutting portion of the two cover bodies 13. By adopting the above technical solution, when the internal air pressure of the liquid cooling tank 1 increases, the steam will enter the voltage stabilizing tank 2 and compress the elastic container 16 to complete pressure relief. The elastic container 16 is in a natural state when the steam does not enter, and the air inside the elastic container 16 is squeezed out when it is compressed. And since the exhaust port 15 is aligned with the abutting portion of the two cover bodies 13, when the elastic container 16 is compressed, the air flows towards the junction of the two cover bodies 13, and after being guided by the inclined surface of the cover body 13, it flows to both sides, thereby dissipating heat from the cover body 13; this method is beneficial to reducing the influence of the ambient temperature on heat dissipation.

[0060] The voltage stabilizing tank 2 is located directly above the liquid cooling tank 1. A hydraulic cylinder 19 for driving the voltage stabilizing tank 2 to lift is fixed on the liquid cooling tank 1, and an extrusion portion 20 abutting against the upper surface of the tank cover 8 is fixed at the bottom of the voltage stabilizing tank 2. Since the cover body 13 is inclined, when the internal air pressure in the liquid cooling tank 1 is too high, it is easy to open the cover body 13. By driving the voltage stabilizing tank 2 with the compression cylinder, the voltage stabilizing tank 2 drives the extrusion portion 20 to perform hydraulic locking, and the sealing is reliable. At the same time, the setting of the hydraulic cylinder 19 also facilitates opening the cover body 13 after the voltage stabilizing tank 2 is moved.

[0061] The implementation principle of a two-phase liquid cooling system with a voltage stabilizing device in an embodiment of the present application is as follows: when the coolant in the liquid cooling tank 1 absorbs the heat dissipated by the server 4 and forms steam, the steam condenses and flows back after contacting the condensation component 9. When the server 4 generates too much heat and the steam condensation speed is too late, the steam will enter the voltage stabilizing tank 2 from the air outlet pipe 5. At this time, the elastic container 16 will be compressed, and the elastic container 16 is compressed; when the steam exceeds the limit and causes the internal pressure in the liquid cooling tank 1 to be too high, the safety exhaust valve 21 opens. By controlling the opening and closing of the cooler 18, the elastic container 16 is continuously scaled so that the air in the elastic container 16 continuously blows towards the cover body 13.
