DETAILED DESCRIPTION

[0027] In order to facilitate the understanding of the present invention, a more comprehensive description of the present invention will be given below with reference to the relevant drawings.

[0028] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to another element and integrated therewith, or there may be an intermediate element at the same time. The terms "installed", "one end", "the other end" and similar expressions used herein are for illustrative purposes only.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art. The terms used in the specification herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0030] On the one hand, a server component 120 with automatic cooling capacity adjustment is provided. The server component 120 with automatic cooling capacity adjustment includes a server shell 121. The server shell 121 is provided with a cooling through hole 122. The cooling through hole 122 is used to input coolant into the server shell 121. An automatic adjustment component 124 is also provided on the server shell 121 corresponding to the position of the cooling through hole 122. The automatic adjustment component 124 is used to adjust the flow rate of the coolant input into the cavity of the server shell 121.

[0031] An automatic adjustment component 124 is also provided on the server shell 121 at a position corresponding to the cooling through hole 122. The automatic adjustment component 124 can adjust the flow rate of the coolant input into the cavity of the server shell 121, that is, the automatic adjustment component 124 can adjust the flow rate of the coolant entering the cavity of the server shell 121 from the cooling through hole 122 according to the power of the server component 120, so that the server component 120 can adapt to the corresponding coolant flow rate according to its own power, that is, the server component 120 can automatically adjust the cooling capacity according to its own power to maximize the cooling liquid efficiency.

[0032] On the other hand, a liquid cooling cabinet 110 is provided, which includes a cabinet shell 113 and the above-mentioned server component 120. The cabinet shell 113 is provided with an installation cavity 111 and a pressure chamber 112. The installation cavity 111 is used for plugging and installing the server component 120. When the server component 120 is installed in the installation cavity 111, the pressure chamber 112 transports cooling liquid to the server shell 121 through the cooling through hole 122. The automatic adjustment component 124 is used to adjust the flow rate of cooling liquid transported by the pressure chamber 112 to the server shell 121.

[0033] In the prior art, the immersed liquid-cooled server assembly 120 is filled with liquid from the pressure chamber 112 at the bottom of the installation cavity 111 of the liquid-cooled cabinet 110, and then flows into the server. After heat exchange with the heat-generating components, the hot coolant rises faster and finally overflows. The liquid inlet at the bottom of the server shell 121 is a perforated liquid inlet. The installation cavity 111 of the liquid-cooled cabinet 110 will install multiple server assemblies 120, and the power of each server assembly 120 varies greatly. For example, some server assemblies 120 have a power of 300 to 500W, and others have a power of 700 to 900W. At this time, the high-power server assembly 120 cannot obtain sufficient pressure to adapt to a higher flow rate or flow; while the low-power server assembly 120 has a pressure overload and adapts to a lower flow rate or flow, resulting in a large waste of cooling capacity, making the overall efficiency of the liquid-cooled cabinet 110 low. By setting an automatic regulating component 124 corresponding to each server component 120, the flow of the coolant entering the bottom of the server shell 121 from the pressure chamber 112 is regulated, so that the cooling capacity is reasonably used and the overall performance of the liquid cooling cabinet 110 is improved.

[0034] In a preferred embodiment, the pressure chamber 112, the cooling through hole 122 and the inner cavity of the server shell 121 form a fluid channel, and the fluid channel is used to transport cooling liquid; the automatic adjustment component 124 includes an adjustment drive device 125 and an adjustment plate 126, the drive device and the adjustment plate 126 are arranged on the server shell 121, the adjustment drive device 125 and the adjustment plate 126 are drivingly connected, the adjustment plate 126 is arranged corresponding to the cooling through hole 122, and the adjustment plate 126 is used to adjust the size of the flow cross-section of the fluid channel.

[0035] By adjusting the size of the flow cross section, the size of the coolant flow can be adjusted. The cooling through hole 122 is connected to the cooling through hole 122 and the inner cavity of the server housing 121 respectively. The adjustment plate 126 is arranged corresponding to the cooling through hole 122, which makes it easier to arrange the adjustment plate 126. The drive device and the adjustment plate 126 are arranged on the server housing 121, which makes it easier to design the automatic adjustment component 124 and the server housing 121 as a whole.

[0036] In a preferred embodiment, the cooling through hole 122 is disposed at the bottom of the server housing 121, the adjustment drive device 125 is an electric drive device, and an output shaft 128 is disposed at the output end of the adjustment drive device 125. The specific structure of the adjustment drive device 125 is described below.

[0037] Implementation method 1: Please refer to Figure 1 to Figure 2 The output shaft 128 is further provided with a lifting inclined block 129 at one end away from the adjusting driving device 125. The output shaft 128 is driven by the adjusting driving device 125 to telescope in the left-right direction. The adjusting plate 126 is provided with a lifting inclined surface ( Figure 2 The adjusting plate 126 is on the far right side, the lifting slope can be lifted by the lifting slope block 129, the lifting slope abuts against the lifting slope block 129, the adjusting plate 126 is located above the cooling through hole 122, the adjusting plate 126 is provided with a flow regulating through hole 127, the flow regulating through hole 127 is staggered with the cooling through hole 122, the cooling through hole 122 and the regulating through hole 127 are staggered, the lifting slope block 129 is used to drive the adjusting plate 126 to move up and down, so that the adjusting plate 126 is close to or away from the cooling through hole 122. The output shaft 128 is driven by the adjusting drive device 125 to telescope in the left and right directions, driving the lifting slope block 129 to move left and right, and further driving the adjusting plate 126 to move up and down. The left and right telescopic movement referred to is to attach Figure 1For reference. The adjustment plate 126 is a U-shaped sliding plate that opens upward, and the front and rear side walls of the adjustment plate 126 and the front and rear side walls of the server housing 121 can slide and abut against each other. The drive device 125 can adopt an existing electric telescopic rod. When it is necessary to lift the adjustment plate 126, the output shaft 128 extends to the left, and the lifting inclined surface of the lifting block 129 moves to the left to lift the adjustment plate 126; when the output shaft 128 shortens to the right, the lifting inclined surface of the lifting block 129 moves to the right to make the lifting inclined surface and the adjustment plate 126 descend due to the weight. When the adjustment plate 126 completely abuts and covers the inner bottom wall of the server housing 121; the cooling through hole 122 is completely closed, and the flow rate of the coolant entering the server housing 121 is equal to zero or close to zero. When the adjustment plate 126 moves upward, the gap between the adjustment plate 126 and the bottom wall of the server housing 121 gradually increases, that is, the effective flow cross-section of the fluid channel for the coolant to flow through gradually increases, and the flow rate of the coolant flowing into the server housing 121 also gradually increases to a maximum value. For example, when the gap between the two changes from 0 cm to 2 cm, the flow rate gradually increases. When the gap between the two is greater than 2 cm, the flow rate reaches the maximum value and does not change.

[0038] Implementation method 2: Please refer to Figure 3 to Figure 4 ,in Figure 4 The cooling through hole 122 is adjusted from the connected state to the closed state, that is, the flow rate of the corresponding coolant is adjusted from the state of large flow rate to the state of small flow rate. The output shaft 128 is connected to the adjustment plate 126 at one end away from the adjustment drive device 125. The output shaft 128 drives the adjustment plate 126 to move left and right. The adjustment plate 126 is located above the cooling through hole 122 and abuts on the bottom inner wall of the server shell 121. The adjustment plate 126 is provided with a flow adjustment through hole 127; when the adjustment plate 126 moves left and right, the adjustment plate 126 can cover the cooling through hole 122 or adjust the size of the cross-sectional area of ​​the connection between the cooling through hole 122 and the adjustment through hole. The adjustment plate 126 is a U-shaped sliding plate with an upward opening. The front and rear side walls of the adjustment plate 126 and the front and rear side walls of the server shell 121 can slide and abut. The front and rear side walls of the adjustment plate 126 and the front and rear side walls of the server shell 121 can slide and abut to limit the rotation and forward and backward movement of the adjustment plate 126. The drive device 125 can adopt an existing electric telescopic rod. When the adjustment plate 126 needs to be moved left and right, the output shaft 128 can be moved left and right. Of course, in some embodiments, the adjustment drive device 12 uses a rotary motor, the output shaft 128 is an output screw, and a threaded hole is provided on the adjustment plate 126. The rotation is converted into the left and right movement of the adjustment plate 126 through the cooperation of the output screw and the threaded hole.

[0039] Implementation method 3: Please refer to Figures 5 and 6 ,in Figure 6The process of adjusting the cooling through hole 122 from a low flow state to a high flow state is shown. The end of the output shaft 128 away from the adjustment drive device 125 is connected to the adjustment plate 126. The output shaft 128 drives the adjustment plate 126 to rotate. A plurality of adjustment plates 126 are arranged at intervals along the front-to-back direction. The adjustment plate 126 is used to adjust the flow cross section of the cooling through hole 122. The flow cross section size affects the flow of the coolant from the cooling through hole 122 into the server housing 121. When the flow needs to be reduced, please refer to Figure 6 , rotating the adjusting plate 126 in one direction makes the cross section of the adjusting plate 126 and the cooling through hole 122 gradually narrow, and the flow rate of the coolant should be reduced accordingly. When the acute angle between the adjusting plate 126 and the cooling through hole 122 is close to 0° (i.e., the two are in the same plane), the adjusting plates 126 are stacked in sequence along the front-to-back direction, and the cooling through hole 122 is in a closed state, i.e., the flow rate is zero or close to zero. When the flow rate needs to be increased, rotating the adjusting plate 126 in another direction makes the cross section of the adjusting plate 126 and the cooling through hole 122 gradually increase, and the flow rate of the coolant should be increased accordingly. When the adjusting plates 126 and the cooling through hole 122 are perpendicular or close to 90°, the flow rate of the coolant flowing through the cooling through hole 122 is close to the maximum value.

[0040] Please refer to Figure 1 In a preferred embodiment, a heat sink 123 and electronic components to be cooled are disposed in a server housing 121, wherein a portion of the electronic components with higher power is disposed on the heat sink 123, and the liquid cooling cabinet 110 is an immersion liquid cooling cabinet 110. When the server assembly 120 is working, the heat sink 123 and the electronic components to be cooled are immersed in the coolant.

[0041] The heat dissipation fins 123 are provided to increase the heat dissipation efficiency of the electronic components with higher power, and further improve the utilization of the cooling capacity by the server assembly 120. For example, a CPU is provided on the heat dissipation fins 123.

[0042] In a preferred embodiment, the automatic adjustment component 124 also includes a temperature sensor, a controller, an adjustment drive device 125 and an adjustment plate 126. The adjustment drive device 125 and the adjustment plate 126 are driven and connected. The adjustment plate 126 is used to adjust the flow rate of the coolant delivered by the pressure chamber 112 to the server shell 121. The adjustment drive device 125 and the temperature sensor are both connected to the controller signal. The temperature sensor is arranged in the cabinet shell 113 and is used to detect the temperature of the coolant and / or electronic components in the cabinet shell 113. The controller also adjusts the adjustment plate 126 through the temperature signal delivered by the temperature sensor.

[0043] When a server component 120 has different powers in different usage states, each server needs to adjust the flow of coolant under different working conditions. The temperature sensor and the controller cooperate to well detect the working states of the server component 120 with different powers. For example, when the server component 120 is in a high-power working state, the temperature inside it will increase. The temperature sensor detects the temperature of the server component 120, and the controller controls the adjustment drive device 125 to increase the flow of coolant into the server component 120, so that the temperature of the server component 120 is reduced again.

[0044] Please refer to Figures 8 to 9 In a preferred embodiment, the pressure chamber 112 is provided with an equalizing flow hole 116, which can be connected to the cooling through hole 122 respectively, and a plurality of cut-off mechanisms 114 are correspondingly provided on the pressure chamber 112, and the cut-off mechanism 114 has a trigger state and a free state; when the server component 120 is installed in the installation cavity 111, the cut-off mechanism 114 is in the trigger state, and the pressure chamber 112 can transport coolant to the server shell 121 through the cooling through hole 122; when the server component 120 is pulled out of the installation cavity 111, the corresponding cut-off mechanism 114 is in the free state, and the cut-off mechanism 114 disconnects the corresponding equalizing flow hole 116 from the cooling through hole 122.

[0045] Please refer to Chinese patent document CN117177536A (the patent name is a cabinet with a coolant distribution function) for the coolant distribution function of the liquid cooling cabinet 110 realized by the cut-off mechanism 114. The server component 120 (i.e., the corresponding server) can be installed and connected to the corresponding fluid channel as soon as it is inserted into the corresponding position through the cut-off mechanism 114, and the server component 120 can be disassembled and the corresponding fluid channel can be closed as soon as it is pulled out of the plug-in installation opening. Please refer to CN117177536A for a more specific implementation of the coolant distribution and cut-off mechanism 114. It should be pointed out that the coolant flow direction in CN117177536A: the coolant can pass through the cavity below the cut-off mechanism 114, the equalizing flow hole 116, the liquid through hole, the cooling through hole 122 and the corresponding server shell 121 (corresponding to its installation shell) in sequence. The cut-off mechanism 114 is used to close or open the equalizing flow hole 116 to ensure that the cavity below the cut-off mechanism 114 and the inner cavity of the server shell 121 are connected and disconnected. Compared with the utility model, the cavity below the cut-off mechanism 114 is a pressure chamber 112, and the pressure chamber 112 has high pressure; secondly, the server housing 121 of the utility model is also provided with an automatic adjustment component 124, which is used to adjust the flow of the coolant entering the server housing 121. The cut-off mechanism 114 and the automatic adjustment component 124 cooperate with each other. When a server component 120 needs maintenance or is pulled out from the liquid cooling cabinet 110 for other reasons, the cut-off mechanism 114 disconnects the equalizing flow hole 116 corresponding to the server, and the position of the pressure chamber 112 stops outputting the coolant; when the server is installed at this position again, the cut-off mechanism 114 is triggered, so that the corresponding equalizing flow hole 116 is opened, connecting the pressure chamber 112, the equalizing flow hole 116, the cooling through hole 122 and the inner cavity of the server housing 121, and the position of the pressure chamber 112 supplies the coolant to the server component 120, and the automatic adjustment component 124 adjusts the flow of the coolant to achieve maximum utilization of the coolant.

[0046] Furthermore, the liquid cooling cabinet 110 (i.e., corresponding to its casing) is provided with an installation cavity 111 in the vertical direction, and a plug-in installation opening connected to the installation cavity 111 is also provided at the upper end, and a supporting partition frame is provided at the lower end of the installation cavity 111, and the supporting partition frame divides the installation cavity 111 into a plurality of fluid channels, and the supporting partition frame is provided with liquid holes corresponding to the fluid channels, and the liquid holes are generally formed by grille holes on the supporting partition frame; the cut-off mechanism 114 includes a first cut-off plate and a reset spring, and the first cut-off plate and the reset spring are located below the supporting partition frame, and the first cut-off plate and the reset spring are connected; a first trigger component extending upward is also provided at the upper end of the first cut-off plate; the supporting partition frame is provided with a movable through hole for the first trigger component to move up and down; in a free state, the first cut-off plate abuts against the lower surface of the supporting partition frame and covers the corresponding liquid hole, and the first trigger component extends upward compared to the supporting partition frame. When the server component 120 is plugged and installed into the fluid channel through the plug-in installation opening, the server component 120 (i.e., the corresponding server) contacts the first trigger component and triggers the first cut-off plate to move downward, and the reset spring is pressed downward to compress the first cut-off plate, so that the first cut-off plate is in a triggered state. The first cut-off plate is opened relative to the fluid channel, so that the fluid hole is connected to the fluid channel, thereby connecting the input mechanism, the fluid channel, and the output mechanism in sequence. When the server component 120 is pulled out of the plug-in installation opening, since the first trigger component loses the action of the server component 120, the first cut-off plate is driven to move upward under the action of the restoring force of the reset spring until the first cut-off plate abuts against the lower surface of the supporting partition frame and covers the corresponding fluid hole. After the first cut-off plate, the first trigger component, and the reset spring are reset, the cut-off mechanism 114 re-enters a free state. The liquid cooling cabinet 110 is provided with a plurality of fluid channels for the circulation of cooling medium. The input end of the fluid channel is connected to the input mechanism, and the output end of the fluid channel is connected to the output mechanism. The cut-off mechanism 114 is respectively provided corresponding to the fluid channels, thereby forming multiple relatively independent fluid channels; the multiple fluid channels cool the servers placed therein respectively; the cut-off mechanism 114 can independently control the connection and disconnection between each cut-off mechanism 114, the input mechanism, the fluid channel and the output mechanism. The cut-off mechanism 114 has a trigger state and a free state. By switching between the trigger state and the free state, the cut-off mechanism 114 can avoid short circuit of the fluid in the cabinet when the electronic equipment such as the server to be cooled is removed from the fluid channel; thus the cooling efficiency is greatly improved.

[0047] Please refer to Figures 7 to 9 , on the other hand provides liquid cooling cabinets.

[0048] In a preferred embodiment, the liquid cooling cabinet 110 is also provided with a liquid level regulating component 100, the liquid level regulating component 100 includes an oil pump 104, an oil storage tank 115 is provided on the liquid cooling cabinet 110, the installation cavity 111 is used to accommodate cooling liquid, the installation cavity 111 is connected to the oil storage tank 115, and the oil pump 104 is used to transport the cooling liquid in the installation cavity 111 to the oil storage tank 115 or to transport the cooling liquid in the oil storage tank 115 to the installation cavity 111.

[0049] The oil pump 104 is used to deliver the coolant in the installation cavity 111 to the oil storage tank 115 or to deliver the coolant in the oil storage tank 115 to the installation cavity 111. The following problems can be avoided:

[0050] (1) The existing immersion liquid cooling cabinet 110 adopts an overflow solution. The liquid is pumped out to the heat exchange system through a pump. The heat exchange system cools the coolant and then returns it to the cavity. The liquid is affected by characteristics such as expansion and volatilization during the heating process. When the liquid is injected in the early stage, it is necessary to consider that the liquid will expand higher than the overflow tank, causing a liquid short circuit, or the liquid will evaporate and fall below the liquid level, requiring manual refilling and liquid level adjustment. (2) When refilling the liquid in the computer room of an unmanned data center, it is necessary to refill the liquid on site. (3) When the equipment is transported with liquid, a separate sealing cover is required, which affects the convenience of use. (4) When transporting liquid, the current line cannot be fully sealed and leaks. (5) The extraction and addition of liquids require separate oil barrel pipe accessories.

[0051] In a preferred embodiment, the liquid level regulating assembly 100 further includes a liquid level controller 101 and a liquid level sensor 102. The liquid level sensor 102 is used to monitor the liquid level of the coolant in the installation cavity 111. The liquid level controller 101 is signal-connected to the oil pump 104 and the liquid level sensor 102, respectively.

[0052] The liquid level controller 101 receives the liquid level signal monitored by the liquid level sensor 102. When the liquid cooling cabinet 110 is in operation, the liquid level controller 101 controls the direction of the oil pump 104 pumping the coolant according to the liquid level signal, thereby realizing liquid level regulation and detection.

[0053] In a preferred embodiment, when the liquid cooling cabinet 110 is in working state, the liquid level controller 101 controls the oil pump 104 according to the transmission signal of the liquid level sensor 102, so that the coolant in the liquid cooling cabinet 110 is at the working liquid level, and the height difference between the working liquid level and the server component 120 is 0 to 2 cm; when the liquid cooling cabinet 110 is in the transportation state, the oil pump 104 pumps the coolant in the liquid cooling cabinet 110 into the oil storage tank 115, so that the height difference between the upper end plug-in installation opening of the liquid cooling cabinet 110 and the liquid level of the coolant in the liquid cooling cabinet 110 is greater than 10 cm.

[0054] When in working state, the oil pump 104 pumps the coolant in the oil storage tank 115 into the liquid cooling cabinet 110 or pumps the coolant in the liquid cooling cabinet 110 into the oil storage tank 115 according to the current liquid level of the coolant, so as to ensure that the coolant in the liquid cooling cabinet 110 is at the working liquid level. The height difference between the working liquid level and the server component 120 is 0 to 2 cm, so as to ensure that the server component 120 is immersed in the coolant when working, so as to avoid short circuit of excessive coolant above the server component 120, thereby improving the cooling efficiency of the coolant. The upper end is also provided with a plug-in installation opening connected to the installation cavity 111, and the server component 120 is plugged and installed into the installation cavity 111 through the plug-in installation opening. When the liquid cooling cabinet 110 is in the transport state, the oil pump 104 pumps the coolant in the liquid cooling cabinet 110 into the oil storage tank 115, so that the liquid level of the coolant in the liquid cooling cabinet 110 drops, ensuring that the liquid level is at an appropriate safety distance from the plug-in installation opening. When the liquid cooling cabinet 110 is in the transport state, the coolant spills out from the plug-in installation opening. In the transport state, all or most of the coolant can be sent to the oil storage tank 115, generally ensuring that the height difference between the plug-in installation opening and the liquid level of the coolant in the liquid cooling cabinet 110 is greater than 10 cm. The height difference between the working liquid level and the server assembly 120 can be the height difference between the top of the server assembly 120 as a whole or the highest height of the electronic components in the server assembly 120 and the working liquid level.

[0055] In a preferred embodiment, the oil pump 104 is a bidirectional oil pump 104, the liquid level regulating assembly 100 also includes an oil pipe 105, the installation cavity 111 and the oil storage tank 115 are connected through the oil pipe 105, the oil pump 104 is arranged on the oil pipe 105, and the oil pipe 105 is also provided with a solenoid valve 103, the solenoid valve 103 is used to control the connection and disconnection of the oil pipe 105, and the solenoid valve 103 is connected to the liquid level controller 101 signal.

[0056] The bidirectional oil pump 104 means that the oil pump 104 can rotate forward and reverse to deliver the coolant in the installation cavity 111 to the oil storage tank 115 or deliver the coolant in the oil storage tank 115 to the installation cavity 111. Controlling the connection and disconnection of the oil delivery pipe 105 can control the connection and disconnection between the oil storage tank 115 and the installation cavity 111. The liquid level adjustment component 100 of the utility model is equivalent to an automatic liquid level compensation control system. The liquid level is sensed by the liquid level sensor 102, and the liquid level controller 101 adjusts the electromagnetic valve 103 and the oil pump 104 to open and close, so that the liquid in the installation cavity 111 is kept within a reasonable range. And it has at least the following advantages:

[0057] (1) Unattended automatic refilling and adjustment according to the liquid level reduces the convenience of on-site maintenance, and the real-time adjustment of the liquid level is more accurate. (2) When transporting liquid, the liquid in the installation cavity 111 is passed through the solenoid valve 103 and the oil pump 104 (forward and reverse) to pump the liquid (into / out) of the oil storage tank 115 through the same pipeline. (3) When transporting liquid, the liquid is stored in the oil storage tank 115, and the top cover does not need special sealing treatment and a separate sealing cover, which makes the appearance simpler. (4) When transporting liquid, the liquid is stored in the oil storage tank 115, and the line does not need special treatment, which reduces costs. (5) Reduce the cost of oil drums and pipe fittings. (6) Reduce the cost of manual refilling.
