The data center is a consumer with large power consumption, and electronic equipment and a refrigerating unit which run continuously all the year round consume a large amount of electric energy, and an effective heat dissipation mode is adopted for the data center to reduce the power consumption of the refrigerating unit, so that the energy conservation of the whole data center is realized.

Most of the existing data center machine rooms adopt an air cooling technology to cool electronic equipment. A data center machine room is required to be matched with a plurality of air conditioners, and the heat generated in the electronic equipment is taken away through the cool air generated by the air conditioners, so that the cooling of the data center machine room is realized.

However, because the heat generated by the electronic equipment in the machine room is large, a large amount of cold air is required to dissipate heat for the electronic equipment, and then the air conditioner is required to continuously operate to generate cold air, so that the power consumption is huge, and the PUE of the data center is high.

Referring to fig. 1 to 4H, the liquid cooling cabinet includes: the inner container 1, the inner container 1 has open-ended and holds chamber 2, holds the intracavity and sets up flow equalizing plate 3, has a certain distance between flow equalizing plate 3 and the bottom that holds chamber 2 to form a coolant liquid chamber 4 that supplies the coolant liquid to pour into between flow equalizing plate 3 and the bottom surface that holds chamber 2. The flow equalizing plate 3 is provided with a plurality of rows of first through holes 5 for cooling liquid to pass through, the space above each row of first through holes 5 is used for deploying electronic equipment, a second through hole is formed in a body of the electronic equipment, and cooling liquid enters the body of the electronic equipment from the second through hole. The body of the electronic device is not illustrated in the figures. Electronic devices such as devices that generate a significant amount of heat for servers and the like in a data center room.

The liner 1 is, for example, a rectangular parallelepiped, and the front, rear, left, right, and bottom surfaces of the liner 1 are, for example, stainless steel plates, and the steel plates are welded by a welding technique to obtain the liner 1, and to ensure the water storage capacity of the liner 1. The stainless steel plate is at least 304 stainless steel, and can be made of other materials and difficult to deform.

At least one liquid inlet 6 and at least one liquid outlet 7 are arranged on the first side wall and the second side wall of the liner 1, the position of the liquid outlet 7 is higher than the position of the liquid inlet 6, the first side wall is also called a left side wall, the second side wall is also called a right side wall, and obviously, the first side wall and the second side wall are two opposite side walls of the containing cavity. The bottom of first lateral wall with the bottom of second lateral wall all sets up drainage portion 8 and sets up shunt cavity 9 of drainage portion 8 below, shunt cavity 9 the top surface with flow equalizing plate 3 parallel and level. The liquid inlet 6 opens into the drainage portion 8. After entering from the liquid inlet 6, the cooling liquid enters the drainage part 8, then enters the cooling liquid cavity 4 below the flow equalizing plate 3 through the drainage part 8, and enters the space above the flow equalizing plate 3 through the first through hole 5 on the flow equalizing plate 3, namely the space above the first through hole 5. Because the second through hole is formed in the body of the electronic equipment, the cooling liquid enters the body of the electronic equipment through the second through hole, and therefore heat generated by the electronic equipment is taken away.

The first side wall and the second side wall of the liner 1 are respectively provided with a water return cavity 10, the water return cavity 10 is far away from the drainage part 8, an inlet of the water return cavity 10 is positioned in an upper space of the containing cavity, an outlet of the water return cavity 10 is communicated with the liquid outlet 7, and the upper space is a space above the electronic equipment.

A pipeline 13 is arranged between the liquid inlet 6 and the drainage part 8, and a valve 14 is arranged on the pipeline 13. When valve 14 is opened, external coolant is injected through inlet 6. The valve 14 can be a butterfly valve and the like, is easy to open and close, has a smaller appearance and does not occupy redundant space. When the butterfly valve is damaged, only the butterfly valve needs to be replaced, and the cooling liquid in the containing cavity does not need to be replaced after being evacuated, so that the operation and maintenance working efficiency is further improved, and analysis of cooling liquid leakage in the containing cavity 2 caused by damage of the valve 14 can be reduced. The valve 14 can also control the flow rate of the coolant injected into the drain 8.

When the cooling liquid is needed to be injected, the electronic equipment is inserted into the accommodating cavity 2, the liquid injection trolley is connected to the liquid inlet 6, after the liquid inlet 6 and the liquid injection trolley are locked through the buckle, the valve 14 is opened, the cooling liquid enters the pipeline 13 from the liquid inlet 6, enters the drainage part 8 under the guidance of the pipeline 13, and then enters the diversion cavity 9. The drainage part 8 is used for guiding the cooling liquid to the bottommost part of the accommodating cavity 2 and preventing the electronic equipment from being failed due to impact on components on the body of the electronic equipment caused by too fast flow speed of the liquid inlet 6. The diversion cavity 9 is used for sending the cooling liquid entering the drainage part 8 into the cooling liquid cavity 4 below the flow equalizing plate 3. After the cooling liquid enters the cooling liquid cavity 4, the cooling liquid is continuously injected, so that the cooling liquid enters the space above the first through holes 5 through the first through holes 5 on the flow equalizing plate 3. The space above the first through hole 5 is used for disposing electronic equipment, a second through hole is formed in the body of the electronic equipment, and cooling liquid enters the body of the electronic equipment from the second through hole. The second through holes may be provided at the bottom of the electronic device or on each face of the electronic device.

After the cooling liquid passes through the electronic equipment, heat generated by the electronic equipment is brought into the upper space. Based on the principle of thermal expansion and contraction of liquid, the heat flow can be located in the upper space, namely, the top of the electronic equipment. As the cooling liquid is continuously injected from the liquid inlet 6, the level of the cooling liquid in the accommodating chamber 2 gradually increases. When the height of the cooling liquid is higher than the inlets of the water return cavities 10 on the first side wall and the second side wall, namely the left side wall and the right side wall, of the liner 1, the heat flow enters the water return cavities 10 and is then conveyed to the outside from the liquid outlet 7. The effect of the water return cavity 10 is to prevent the cooling liquid from flowing out from the liquid outlet 7 after half of the cooling liquid is injected into the cold accommodating cavity 2, so that the effect of cold and hot circulation cannot be achieved, and complete heat exchange to the electronic equipment cannot be realized.

Referring to fig. 4D and 4F, in the embodiment of the present application, the water return cavity 10 is approximately inverted "L" shaped, which increases the water return area to a certain extent, i.e. increases the volume of the water return cavity 10. The advantages are that: after the cooling liquid enters the cooling liquid cavity 4, the flow rates of the cold and hot flows are different under the resistance of components in the flow equalizing plate 3 and the electronic equipment, the flow rate of the cold flow is small, and the flow rate of the hot flow is large. If the water return area of the water return cavity 15 is small, the phenomenon that the electronic equipment is exposed out of the cooling liquid and the liquid level drops suddenly due to slow cooling liquid supplement can occur, which is not preferable. In this embodiment of the application, through the area that increases the return water cavity 10 for get into the heat flux of return water cavity 10 and increase, more than the heat flux that goes out from liquid outlet 7, and then make most heat fluxes all store in holding chamber 2, thereby can not take place the liquid level difference.

Referring to fig. 3 to 4H, the liquid cooling cabinet provided in the embodiment of the present application can enable electronic devices such as a server to be completely immersed in the cooling liquid, circulate the cooling liquid in the liquid cooling cabinet through an external heat exchange device, take away redundant heat of the electronic devices, ensure that the temperature of each electronic device is constant for a long time, ensure that the electronic devices operate normally, and reduce maintenance time and efficiency. Moreover, the immersed environment effectively avoids adverse effects of moisture, dust and the like on the electronic equipment. In addition, a fan is not needed, so that the problems of noise and vibration are effectively solved.

The liquid cooling rack that this embodiment provided, including the inner bag, the inner bag has open-ended and holds the chamber, holds the intracavity and sets up the board that flow equalizes, flow equalizing board and hold and form the coolant liquid chamber between the ground in chamber, set up the first through-hole of multiple rows on the board that flow equalizes. The bottom of the first lateral wall and the second lateral wall of the inner container is provided with a drainage part, a flow distribution cavity is arranged below the drainage part, the top surface of the flow distribution cavity is flush with the flow equalization plate, a liquid inlet is led to the drainage part, and the first lateral wall and the second lateral wall are two opposite lateral walls of the accommodating cavity. And liquid outlets are also formed in the first side wall and the second side wall. The liquid cooling cabinet also comprises a top cover which is matched with the opening of the accommodating cavity. After entering from the liquid inlet, the cooling liquid enters the drainage part, then enters the cooling liquid cavity below the flow equalizing plate through the drainage part, and enters the space above the flow equalizing plate through the first through hole on the flow equalizing plate. Because the second through hole is formed in the body of the electronic equipment, the cooling liquid enters the body of the electronic equipment through the second through hole, and therefore heat generated by the electronic equipment is taken away. By adopting the scheme, the data center machine room is cooled in a liquid cooling mode, so that the purposes of reducing the energy consumption of the data center machine room and improving the PUE of the data center machine room are realized. Moreover, the liquid cooling cabinet can ensure the operation temperature of the electronic equipment, and simultaneously, can accurately control the operation temperature, and is not influenced by the environment to the greatest extent. Compared with an air cooling mode, the air cooling type air conditioner has the advantages that the power consumption and the occupied area are greatly reduced, meanwhile, noise pollution is reduced, energy is saved, and the consumption of water resources is reduced.

Referring to fig. 4G and fig. 4H again, optionally, the third side wall of the accommodating cavity 2 is provided with a first guiding strip 15, and the fourth side wall is provided with a first guiding strip 16. The third side wall and the fourth side wall are two opposite side walls of the accommodating cavity. The third side wall is also called the front side wall of the receiving chamber and the fourth side wall is also called the rear side wall of the receiving chamber. The first guide strip 15 and the first guide strip 16 are used for guiding the electronic device into the accommodating cavity 2. The first guide strip 15 and the first guide strip 16 serve to guide the electronic devices into the accommodating cavity 2, and meanwhile normal insertion and extraction of each electronic device can be guaranteed.

Optionally, the inner container 1 is further provided with a waterproof connector mounting hole 28 for connecting a signal line of an electronic device or an exchange to a peripheral device, so that the phenomenon that the cooling liquid in the accommodating cavity 2 leaks and sublimates into gas is avoided.

In the embodiment of the present application, the widths of the first guide bar 15 and the first guide bar 16, which are identical to each other for guiding the same electronic device, may be the same or different. For example, when the electronic device is a rectangular parallelepiped, the widths of the first guide bar 15 and the first guide bar 16 are the same. For another example, when one of the opposite sides of the electronic device is wide and the other is narrow, the widths of the first guide bar 15 and the first guide bar 16 are different.

In addition, the widths of any two first guide bars 15 among the plurality of first guide bars 15 may be the same or different. This is because some electronic devices are relatively narrow and some electronic devices are relatively wide, and the widths of the first guide bar 15 and the first guide bar 16 may be set according to the sizes of the electronic devices.

By adopting the scheme, the purpose of rapidly guiding and installing the electronic equipment into the accommodating cavity is realized.

Optionally, in the foregoing embodiment, a first mounting plate 17 is disposed on a third side wall of the accommodating cavity 2, a second mounting plate 18 is disposed on a fourth side wall of the accommodating cavity, and mounting holes are disposed on the first mounting plate 17 and the second mounting plate 18, respectively, so that when the electronic device is inserted into place under the guidance of the first guide strip 15 and the first guide strip 16, a nut on the electronic device is locked with the mounting holes, thereby achieving the purpose of fixing the electronic device.

In addition, when the electronic equipment is installed in place, the first installation plate 17 and the second installation plate 18 can also play a certain supporting role, so that the phenomenon of floating due to the fact that the dead weight is smaller than the buoyancy generated by the cooling liquid after the electronic equipment is immersed in the cooling liquid is prevented.

Optionally, in the above embodiment, a flow baffle 19 is disposed on the third side wall of the accommodating cavity 2, and the flow baffle 19 is disposed behind the first mounting plate 17, so as to prevent the cooling liquid from entering the power supply unit of the electronic device.

For example, when the heat generated from the electronic device is excessive, the coolant is likely to boil, and the boiled coolant easily flows to the power distribution unit (Power Distribution Unit, PDU), i.e., the power supply unit of the electronic device, mainly the socket part, to damage the power supply unit, causing an accident in serious cases. Therefore, by providing the flow blocking plate 19, the first mounting plate 17 and the flow blocking plate 19 are provided back and forth, and it is possible to prevent the liquid level of the cooling liquid in the housing chamber 2 from rising and entering the power supply unit of the electronic apparatus.

Referring to fig. 4D and fig. 4F again, in an optional embodiment, the liquid cooling cabinet further includes a filling block 20 disposed between the drainage portion 8 and the backwater cavity 10. By providing the filling block 20, the amount of the coolant injected into the accommodating chamber 2 can be reduced.

In this embodiment, the liquid cooling cabinet further includes a top cover 11 for covering the opening of the accommodating cavity 2. Fig. 5 is a schematic diagram of a top cover of a liquid-cooled cabinet according to an embodiment of the disclosure. Fig. 6A is a bottom view of fig. 5, fig. 6B is a top view of fig. 5, fig. 6C is a front view of fig. 5, and fig. 6D is a split view of fig. 5. Referring to fig. 5 to 6D, a visible window 111 is disposed on the top cover 11, the visible window 111 is made of a transparent material, for example, a polycarbonate plate, and an operator can observe the condition inside the liquid cooling cabinet through the visible window 111.

The top cover 11 mainly comprises two parts, one part is a cover body 112 and the other part is a reinforcing member 113, and the cover body 112 and the reinforcing member 113 are the same in size and shape and are combined into a whole to form the top cover 11. The cover 112 is typically exposed to air and the stiffener 113 is provided with mounting holes 114, such as nitrogen spring mounting holes, for mounting the nitrogen springs. The box body of the liner 1 is provided with an air supporting bracket 12 for installing a nitrogen spring. The opening of the top cover 11 is controlled by a nitrogen spring. In addition, the reinforcing member 113 is provided with the mounting hole 114 for mounting the nitrogen spring, and a certain supporting function can be achieved.

Optionally, the liner 1 and the top cover 11 are sealed by a sealing material, and the sealing material does not react with the cooling liquid in the liner 1. After the top cover 11 is closed, the sealing strip is pressed down in a locking manner, so that the sealing strip is deformed to a certain extent, and sealing between the liner 1 and the fixed cover 11 is completed.

Optionally, the above liquid cooling cabinet further includes a first protection member 21, which is formed by welding a metal tube, and is sleeved on the outer edge of the liner 1, where the metal tube included in the first side wall of the first protection member forms a gap for the liquid inlet 6 to extend out of the liquid outlet 7, and the metal tube included in the second side wall of the first protection member 21 forms a gap for the liquid inlet to extend out of the liquid outlet.

Fig. 7 is a schematic structural diagram of a first protection member of a liquid cooling cabinet according to an embodiment of the present application. Fig. 8A is a schematic view of a left side surface of the first protector shown in fig. 7, fig. 8B is a schematic view of a front side surface of the first protector shown in fig. 7, and fig. 8C is a schematic view of a bottom surface of the first protector shown in fig. 7.

Referring to fig. 7 to 8C, the first protection member 21 is a unitary structure formed by welding 316 rectangular stainless steel pipes. Alternatively, it may be 5 parts, welded to the periphery of 5 sides of the liner 1, to form a complete first protection member 21.

In this embodiment of the application, the inner bag of liquid cooling rack is used for holding coolant liquid and electronic equipment, and the density of coolant liquid is bigger generally, and after the chamber 2 that holds of inner bag 1 was full of coolant liquid, the deformation that the inner bag 1 was propped to the coolant liquid of big density is highly likely, and the inner bag 1 warp the back, can take place electronic equipment unable installation scheduling problem in place. Therefore, by providing the first protector 21, the liner 1 can be prevented from being deformed.

Optionally, the above liquid cooling cabinet further includes a second protection member 22, which is sleeved on the outer edge of the first protection member 21, where a first side wall and a second side wall of the second protection member 22 are annular metal tubes, and a third side wall and a fourth side wall of the second protection member 22 are metal plates. Wherein the first sidewall is also referred to as a left sidewall, the second sidewall is also referred to as a right sidewall, the third sidewall is also referred to as a front sidewall, and the fourth sidewall is also referred to as a rear sidewall.

Fig. 9 is a schematic structural diagram of a second protection member of a liquid cooling cabinet according to an embodiment of the present application. Referring to fig. 9, the second protection member 22 is formed by welding metals with different specifications and difficult to deform, for example, the first side wall and the second side wall are rectangular carbon steel tubes, and the third side wall and the fourth side wall are respectively formed by welding 5 carbon steel plates. The carbon steel plate and the rectangular carbon steel pipe are welded as one body, thereby forming the second protector 22. The second protector 22 is welded to the outer side of the first protector 21, and can further prevent the deformation of the liner 1 while playing a certain aesthetic role.

Referring to fig. 4D and 4F again, in the above embodiment, an optional mounting bracket 23 is reserved in the liner 1 for mounting the level gauge. In addition, a temperature sensor mounting hole is reserved in the liner, for example, a thermometer mounting hole is reserved on the first guide strip 15 or the second guide strip 16 for mounting a thermometer. The function of the liquid level meter is: when the electronic equipment is operated, the liquid level change of the cooling liquid in the inner container can be detected at any time so as to supplement the cooling liquid at any time.

In addition, the liquid level height and temperature change in the liquid cooling cabinet can be detected through the heat exchange systems at the two sides of the liquid cooling cabinet, and a series of reactions such as low liquid level alarm or high temperature alarm can be performed.

In this embodiment of the application, liquid cooling rack utilizes level sensor to gather liquid level information, utilizes temperature sensor to gather temperature, feeds back liquid level information and temperature to heat transfer system. The heat exchange system adjusts the cooling liquid entering speed of the liquid inlet according to the temperature information and the liquid level information, and adjusts the heat flow exiting speed of the liquid outlet, so that the temperature in the accommodating cavity 2 is maintained in a reasonable range. After the heat flow is discharged from the liquid outlet, the heat flow can be cooled in a natural cooling mode and the like, so that the energy consumption is greatly reduced.

Referring to fig. 4G again, in the above embodiment, the electronic device is optionally powered by setting a dual PDU. A third side wall of the receiving chamber 2 is provided with a bi-directional mounting hole 24.
