[0002] With the influence of factors such as high power density requirements, energy consumption cost pressure, environmental protection requirements, technological progress, and policy support, liquid-cooled cabinets have developed rapidly. The flow equalization of liquid-cooled cabinets is one of the key factors affecting their development, and the flow equalization of liquid-cooled cabinets will affect the heat dissipation effect and stability of liquid-cooled cabinets.

[0003] The current liquid-cooled cabinets rely on the size of the openings at the bottom to control the flow equalization. It is very difficult to achieve flow equalization with this design, and it is impossible to manually or automatically adjust the flow equalization problem. When dual CDUs supply liquid, the server flow rate in the middle is the lowest, and the component temperature is higher than that of the servers in other positions; when a single CDU supplies liquid, since the bottom flow equalization plate has better flow equalization when used for dual CDUs, the server flow rate far away from the CDU liquid supply is much lower than that in other positions at this time, and the component temperature difference is greater. The heat dissipation situation for the positions with low flow rate is relatively poor, and there is a certain heat dissipation risk. Therefore, there is an urgent need for a liquid-cooled cabinet flow equalization device to adjust the flow equalization problem of the entire liquid-cooled cabinet. Summary of the Invention

[0022] The liquid-cooled cabinet flow uniformity device and method provided by this application. The liquid-cooled cabinet flow uniformity device includes a CDU, a server, and a turbine module and a flow equalizing plate placed in the liquid supply channel at the lower layer of the liquid-cooled cabinet. Among them, the CDU is arranged outside the server and is used to transport the liquid supply into the server.

First, generally speaking, the rotation parameters of the turbine match the real-time environment information in the liquid-cooled cabinet, effectively adjusting the overall state of the entire liquid-cooled cabinet. From a local perspective, further, the position, direction and speed of the turbine can be adjusted in real time according to the calculation method. Compared with the existing method of setting preset positions and preset thresholds for rotation, it has strong scientificity and high flexibility, and the flow uniformity improvement effect is better.

[0023] The following specific embodiments are given to introduce the technical solutions of this application in detail.

[0024] Figure 1 It is a schematic structural diagram of the first embodiment of the liquid-cooled cabinet flow uniformity device provided by this application. Please refer to Figure 1 , the device provided in this embodiment. The liquid-cooled cabinet flow uniformity device includes a CDU, a server, and a turbine module and a flow equalizing plate placed in the liquid supply channel at the lower layer of the liquid-cooled cabinet. Among them,

[0025] The CDU is arranged outside the server and is used to transport the liquid supply into the server.

[0026] The flow equalizing plate is arranged at the bottom of the server and is used to disperse and cool the liquid supply, so that the temperature in the liquid-cooled cabinet is evenly distributed.

[0027] The turbine module is arranged below the flow equalizing plate, and the turbine module is connected to the CDU; the turbine module is used to monitor the operation of the CDU in real time, calculate the temperature distribution of the liquid cooling cabinet based on the operation conditions, determine the rotation direction of the turbine based on the direction attribute in the temperature distribution, determine the rotation speed of the turbine based on the temperature difference attribute in the temperature distribution, and control the rotation of the turbine in the turbine module based on the rotation direction and the rotation speed, so that the temperature difference between the components of the liquid cooling cabinet is less than a threshold value. Among them, the direction attribute in the temperature distribution indicates the direction starting from the high-temperature area and pointing to the low-temperature area, which is represented by the vector direction from the high-temperature central area to the adjacent low-temperature area, and the temperature difference attribute in the temperature distribution indicates the difference between the highest temperature and the lowest temperature in the liquid cooling cabinet.

[0028] Specifically, the threshold value is set according to actual needs. In this embodiment, the specific value of the threshold value is not limited.

[0029] In specific implementation, the turbine module calculates the temperature distribution of the liquid-cooled cabinet according to parameters such as the temperature and flow rate of the cooling liquid supply monitored by the CDU. The temperature distribution of the liquid-cooled cabinet includes a direction attribute and a temperature difference attribute. Taking the boundary divided by temperature, the temperature region of the liquid-cooled cabinet is divided to obtain a high-temperature region and a low-temperature region. The divided regions are associated with adjacent regions. The direction attribute represents the direction from the high-temperature region as the starting point to the low-temperature region. The temperature difference attribute represents the difference between the highest temperature and the lowest temperature in the liquid-cooled cabinet. As an alternative embodiment, the horizontal component of the line connecting the centers of the high-temperature region and the low-temperature region is used as the direction attribute, and the difference between the highest temperature in the high-temperature region and the lowest temperature in the low-temperature region is used as the temperature difference attribute. The number of high-temperature regions and low-temperature regions can be multiple. At this time, taking adjacent high-temperature regions and low-temperature regions as a group, the direction attribute and temperature difference attribute of each group are parameter information. The weight is calculated according to the size of the temperature difference attribute, and the weighted sum is performed using the weight and the parameter information to obtain the comprehensive direction attribute and temperature difference attribute of each group. Specifically calculating the weight according to the size of the temperature difference attribute includes: calculating the weight of the current group according to the proportion of the temperature difference attribute of the current group in the total sum of the temperature difference attributes of all groups, and using this weight as the weight for the weighted sum of the direction attribute and temperature difference attribute of this group. The weighted sum of the direction attribute is specifically the current direction plus the product of the weight value of the current group and 360 degrees, and using this sum value as the weighted direction attribute of the current group. As a preferred embodiment, the weighted direction attributes of different groups with the same current direction are summed to obtain the final direction attribute. For example, starting from the left, the direction attribute of the first group is from the high-temperature region to the low-temperature region, horizontally to the right, and the weighted direction attribute is horizontally to the right and at an oblique angle of 15 degrees upward; the weighted direction attribute of the second group on the left is horizontally to the right and at an oblique angle of 15 degrees upward; the direction attribute of the third group is from the high-temperature region to the low-temperature region, horizontally to the left. At this time, only the weighted direction attributes of the first group and the second group are added. The method provided by the present invention can achieve multiple partitions through temperature, refine the direction attribute and temperature difference attribute, and then accurately calculate the rotation parameters of the turbine, improving the scientific nature of the turbine rotation and further improving the effect of the uniform flow adjustment.

[0030] Further, determining the rotation direction of the turbine based on the direction attribute in the temperature distribution specifically includes:

[0031] Calculating the horizontal component in the direction attribute within a first range in the liquid-cooled cabinet, and determining the rotation direction of the turbine based on the horizontal component. The rotation direction of the turbine is opposite to the direction of the horizontal component.

[0032] Specifically, in different partition cases, the direction attribute may be horizontal or may have a certain angle with the horizontal direction. Considering that the fastest rotation of the turbine drives the flow in the horizontal direction, therefore, calculate the horizontal component of the direction attribute within the first range in the liquid-cooled cabinet, and determine the rotation direction of the turbine based on the horizontal component. The rotation direction of the turbine is opposite to the direction of the horizontal component.

[0033] Specifically, the first range is a circular range centered on the turbine with a radius of r. Among them, the radius is set according to actual needs. In this embodiment, the specific value of the radius is not limited.

[0034] In specific implementation, obtain the direction attribute within the first range in the liquid-cooled cabinet, and decompose the direction attribute into a horizontal component and a vertical component. Among them, the horizontal component is usually the direction parallel to the horizon. Calculate the horizontal components of different regions within the first range through trigonometric functions, calculate the average value of the calculated horizontal components of different regions, and determine the rotation direction of the turbine as the direction opposite to the direction of the horizontal component after averaging.

[0035] Further, determining the rotation speed of the turbine based on the temperature difference attribute in the temperature distribution situation specifically includes:

[0036] Calculate the temperature difference attribute within the first range in the liquid-cooled cabinet;

[0037] Calculate the rotation speed of the turbine based on the temperature difference attribute, and the rotation speed is proportional to the temperature difference attribute;

[0038] The first range is a circular range centered on the turbine with a radius of r.

[0039] Specifically, the first range is a circular range centered on the turbine with a radius of r. Among them, the radius is set according to actual needs. In this embodiment, the specific value of the radius is not limited. The rotation speed of the turbine is proportional to the temperature difference attribute, that is, the greater the temperature difference attribute, the faster the rotation speed of the turbine. The smaller the temperature difference attribute, the slower the rotation speed of the turbine.

[0040] Optionally, after the turbine module controls the turbine in the turbine module to rotate based on the rotation direction and the rotation speed, the turbine module is further configured to detect the change speed of the temperature difference attribute in the temperature distribution situation of the liquid-cooled cabinet within the first range of the liquid-cooled cabinet. If the change speed of the temperature difference attribute is less than the first threshold, adjust the rotation speed of the turbine according to the change speed of the temperature difference attribute.

[0041] Specifically, the change rate of the temperature difference attribute is equal to the ratio of the change value of the temperature difference attribute to time. The first threshold is set according to actual needs. In this embodiment, the specific value of the first threshold is not limited. The adjusted rotation speed of the turbine is equal to the sum of the rotation speed of the turbine before adjustment and the change speed of the turbine, where the change speed of the turbine is equal to the product of the change rate of the temperature difference attribute and the change coefficient. The first range can be the range of a temperature region in the previously divided temperature partition, or can be the circular region within the first radius centered on the turbine. Here, the range of the first region is not specifically limited, and it can be the region of interest of any user. The method provided by the present invention further adjusts the rotation parameters of the turbine according to the change rate of the temperature difference attribute after the turbine starts to rotate. Since the temperature change driven by the liquid flow has a certain lag, and the turbine is always rotating, the present invention only focuses on the temperature change within the first range, and can evaluate the influence of the turbine on the liquid temperature without waiting for the temperature of the entire cabinet to change before changing the control instruction, and predictively controls the rotation of the turbine, improving the scientificity of the control.

[0042] Optionally, when the number of the CDUs is one or more, the device is further configured to calculate the temperature distribution without the turbine in the working state of the liquid-cooled cabinet, determine the number of the turbine modules based on the difference between the highest temperature and the lowest temperature in the temperature distribution without the turbine and the power of the turbine module, and determine the positions of the turbine modules based on the temperature distribution without the turbine, and the number and positions of the turbine modules match the number of the CDUs and the temperature distribution without the turbine.

[0043] Specifically, determining the number of the turbine modules based on the difference between the highest temperature and the lowest temperature in the temperature distribution without the turbine and the power of the turbine module specifically includes:

[0044] Calculating the difference between the highest temperature and the lowest temperature in the temperature distribution without the turbine in the liquid-cooled cabinet;

[0045] Calculating the adjusted temperature based on the power of the turbine module and the preset adjustment time;

[0046] Calculating the number of the turbine modules based on the ratio of the difference between the highest temperature and the lowest temperature in the temperature distribution without the turbine and the adjusted temperature.

[0047] Specifically, the preset adjustment time is set according to actual needs. In this embodiment, the specific value of the preset adjustment time is not limited.

[0048] In specific implementation, the highest temperature and the lowest temperature of the liquid-cooled cabinet are measured under the condition of no turbine temperature distribution. The adjusted temperature is calculated based on the relationship between the power of the turbine module and the preset adjustment time, and the ratio of the difference between the highest temperature and the lowest temperature under the condition of no turbine temperature distribution to the adjusted temperature is determined as the number of turbine modules. For different liquid-cooled cabinet conditions, it is difficult for a single turbine module to complete the control of the turbine module within the target time. Compared with the prior art that directly determines the number of turbine modules based on experience, the method provided by the present invention directly calculates the number of turbine modules according to the temperature adjustment requirements of the liquid-cooled cabinet and the capabilities of the turbine modules, improving the scientificity of the number determination, thereby enhancing the adjustment ability of the turbine module, shortening the liquid temperature adjustment time, and improving the temperature adjustment efficiency.

[0049] Specifically, determining the position of the turbine module based on the no-turbine temperature distribution situation specifically includes:

[0050] Dividing multiple temperature regions based on the no-turbine temperature distribution situation, where the average temperature of each temperature region is different, and the difference between the average temperatures of adjacent temperature regions is greater than the temperature difference threshold;

[0051] Determining the positions of the turbine modules in the first number of temperature regions according to the number of turbine modules;

[0052] Determining the positions of the remaining turbine modules based on the determined positions of the turbine modules and the adjusted temperatures of the determined turbine modules, with turbine modules provided in some of the multiple temperature regions.

[0053] Specifically, the temperature difference threshold is set according to actual needs. In this embodiment, the specific value of the temperature difference threshold is not limited. The first number is set according to actual needs. In this embodiment, the specific value of the first number is not limited.

[0054] In specific implementation, the temperature regions are divided according to the average temperature, and the average temperature of each divided temperature region is different.

[0055] Optionally, when the number of CDUs is 1, the number of turbine modules is the first preset number, and the position of the turbine module is at the first preset distance away from the liquid supply end; when the number of CDUs is multiple, the number of turbine modules is the second preset number, and the position of the turbine module is at the second preset distance from the liquid supply end and is installed in the same flow channel in a symmetric placement manner; where the first preset number is less than the second preset number.

[0056] Specifically, the first preset quantity and the second preset quantity are set according to actual needs. In this embodiment, the specific values of the first preset quantity and the second preset quantity are not limited. For example, in one embodiment, the first preset quantity is half of the number of flow channels. The second preset quantity is the number of flow channels. The first preset distance and the second preset distance are set according to actual needs. In this embodiment, the specific values of the first preset distance and the second preset distance are not limited. For example, in one embodiment, the first preset distance is the product of the total length of the inner liner of the liquid-cooled cabinet and 4 / 7, and the second preset distance is the ratio of the total length of the inner liner of the liquid-cooled cabinet to 4. Figure 2 FIG. Figure 2 is a schematic structural diagram of the flow equalization device of the liquid-cooled cabinet when a single CDU is shown in an exemplary embodiment of the present application. Figure 3 FIG. Figure 3 is a schematic structural diagram of the flow equalization device of the liquid-cooled cabinet when multiple CDUs are shown in an exemplary embodiment of the present application.

[0057] Optionally, when the number of CDUs is multiple, the turbine module is further configured to monitor the working state of the CDUs. If the working state of any one CDU is abnormal, the rotation direction and rotation speed of the target turbine module connected to the CDU with the abnormal working state are adjusted; the rotation direction of the target turbine module is adjusted to the reverse direction, and the rotation speed of the target turbine module is adjusted to the first multiple.

[0058] Specifically, the first multiple is set according to actual needs. In this embodiment, the specific value of the first multiple is not limited.

[0059] In specific implementation, when the working state of any one CDU is abnormal, the rotation direction of the target turbine module connected to the CDU will be adjusted to the opposite direction, and the rotation speed of the target turbine module connected to the CDU will be increased.

[0060] Optionally, a plurality of openings are provided on the flow equalization plate, and the positions and shapes of the openings match the turbine module;

[0061] Wherein, the openings are located above the turbine module. In the vertical direction, the projection of the openings coincides with the projection of the turbine module; the openings are in an irregular shape, with a first central angle in a first direction, and the central angle gradually decreases along the direction of the liquid supply flow; in a second direction, there is a second central angle, and the central angle gradually increases along the direction of the liquid supply flow; wherein, the first direction is the direction of the liquid supply flowing towards the turbine, the second direction is the direction of the liquid supply flowing out of the turbine, and the first central angle is greater than the second central angle.

[0062] Optionally, the device is further configured to determine the specifications of the server, the number of CDUs, and their working status; determine the maximum operating temperature based on the specifications of the server; calculate the total liquid supply of the CDUs operating normally; calculate the average temperature reduction value based on the total liquid supply; and calculate the threshold value based on the difference between the maximum operating temperature and the average temperature reduction value.

[0063] In specific implementation, the maximum operating temperature can be found in the technical document recording relevant specification parameters according to the specifications of the server. Under normal operating conditions, the total liquid supply of the CDU is calculated based on the design data of the CDU, and the average temperature reduction value is calculated based on the calculated total liquid supply. The threshold value is calculated based on the found maximum operating temperature and the calculated average temperature reduction value.

[0064] The liquid-cooled cabinet flow uniformity device provided in this embodiment includes a CDU, a server, and a turbine module and a flow equalizing plate placed in the lower liquid supply channel of the liquid-cooled cabinet. Among them, the CDU is arranged outside the server and is used to transport the liquid supply into the server; the flow equalizing plate is arranged at the bottom of the server and is used to disperse and cool the liquid supply to make the temperature evenly distributed in the liquid-cooled cabinet; the turbine module is arranged below the flow equalizing plate, and the turbine module is connected to the CDU; the turbine module is used to monitor the operation of the CDU in real time, calculate the temperature distribution of the liquid-cooled cabinet based on the operation, determine the rotation direction of the turbine based on the direction attribute in the temperature distribution, determine the rotation speed of the turbine based on the temperature difference attribute in the temperature distribution, and control the rotation of the turbine in the turbine module based on the rotation direction and the rotation speed, so that the temperature difference between each component of the liquid-cooled cabinet is less than the threshold value. Among them, the direction attribute in the temperature distribution represents the direction starting from the high-temperature area and pointing to the low-temperature area, which is represented by the vector direction from the high-temperature central area to the adjacent low-temperature area, and the temperature difference attribute in the temperature distribution represents the difference between the highest temperature and the lowest temperature in the liquid-cooled cabinet. In this way, the speed, direction and other information of the turbine module can be calculated respectively according to different attributes through the real-time temperature conditions within a certain range in the liquid-cooled cabinet, so as to control the rotation of the turbine in the turbine module according to the temperature difference between each component of the liquid-cooled cabinet to adjust the flow uniformity problem of the entire liquid-cooled cabinet. First, generally speaking, the rotation parameters of the turbine match the real-time environmental information in the liquid-cooled cabinet, effectively adjusting the overall state of the entire liquid-cooled cabinet; from a local perspective, further, the position, direction and speed of the turbine can be adjusted in real time according to the calculation method. Compared with the method of setting preset positions and preset thresholds for rotation in the prior art, it has strong scientificity, high flexibility, and better flow uniformity improvement effect.
