Description

Technical Field

[0001] The present application relates to the field of liquid cooling technology, and in particular to a two-phase cold plate liquid cooling cabinet, a control method and a data center. Background Art

[0002] The principle of liquid-cooled cold plate technology is to bring the heat source into contact with the cold plate, transfer the heat of the electronic equipment to the cold plate, and then use the cooling medium in the cooling medium pipe to take the heat out of the cold plate for heat dissipation. Finally, the cooling medium is driven by the circulation system to continuously flow through the heat sink to maintain the stable operation of the liquid cooling system. In related technologies, the cooling medium of the two-phase cold plate cooling system enters the cold plate in liquid form under the drive of the circulation system. After absorbing the heat of the cold plate, part of the cooling medium vaporizes to form a gas-liquid two-phase state and flows out of the cold plate. The gas-liquid mixed cooling medium flowing out of the cold plate passes through the liquid cooling heat exchange module and turns back into liquid phase, and finally re-enters the cold plate under the drive of the circulation pump.

[0003] However, due to the different heat generation of heat-generating components at each node in the existing liquid-cooling cabinet, the existing liquid-cooling cabinet is prone to dry burning of the two-phase cold plate and no phase change in the two-phase cold plate.

In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0067] In the description of the present application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0068] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0069] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0070] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

[0071] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element.

If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0072] The cooling medium of the two-phase cold plate cooling system enters the cold plate in liquid form under the drive of the circulation system. After absorbing the heat of the cold plate, part of the cooling medium vaporizes to form a gas-liquid two-phase state and flows out of the cold plate. The gas-liquid two-phase cooling medium flowing out of the cold plate passes through the secondary cooling system and turns back into liquid phase, and finally re-enters the cold plate under the drive of the circulation pump.

[0073] However, the conventional two-phase cold plate cooling system has the following three problems:

[0074] 1: The liquid supply temperature of the two-phase cold plate 100 is low, and the heating elements have different calorific values, which may cause dry burning of part of the two-phase cold plate 100 and no phase change in the two-phase cold plate 100. In severe cases, the system internal temperature may rise abnormally and the system energy consumption may be excessive.

[0075] 2: Each two-phase cold plate has 100 branches that share a main circulation system. Each branch cannot supply liquid independently. The distribution of the cooling medium flow in each branch is uncontrollable, resulting in uneven cooling effects between different cold plates.

[0076] 3: After the vapor-liquid two-phase cooling fluid enters the confluence pipe, part of the vapor phase fluid cannot be effectively separated in time, and part of the medium will be discharged along with the system exhaust, resulting in medium loss.

[0077] For this purpose, Embodiment 1

[0078] A two-phase cold plate liquid cooling cabinet 10, as shown in FIG1, comprises:

[0079] A plurality of two-phase cold plates 100, used for heat transfer connection with a component to be cooled (such as a server motherboard in FIG. 1);

[0080] The electric-liquid integrated distribution module 200 is arranged at the rear side of the liquid cooling cabinet 10, and is connected to the two-phase cold plate 100 and the parts to be cooled respectively; it is used to collect the power consumption information corresponding to the equipment to be cooled at each node, and / or the cooling capacity information of the two-phase cold plate 100 at each node; and control the flow rate of the fluid in the two-phase cold plate 100 according to the power consumption information and / or the cooling capacity information;

[0081] The liquid cooling heat exchange module 300 includes a receiving cavity provided at the bottom of the liquid cooling cabinet and connected to the electric-liquid integrated distribution module 200, wherein at least three stages of heat exchange units are provided in the receiving cavity;

[0082] System detection module, used to obtain cabinet circulation system parameters of each module and pipeline in the liquid cooling cabinet;

[0083] The system control module is used to connect with the electro-hydraulic integrated distribution module 200, the liquid cooling heat exchange module 300, and the system detection module, and obtain the cabinet circulation system parameters, and / or power consumption information, and / or cooling capacity information to control the working coordination mode of each heat exchange unit in the liquid cooling heat exchange module 300 so that the liquid fluid in the two-phase cold plate 100 of each node absorbs the heat of the part to be cooled and vaporizes to form a vapor fluid flowing out.

[0084] The two-phase cold plate liquid cooling cabinet 10 of this embodiment first collects the power consumption information corresponding to the equipment to be cooled at each node and / or the cooling capacity information of the two-phase cold plate 100 at each node through the electric-liquid integrated distribution module 200; and controls the flow rate of the fluid in the two-phase cold plate 100 according to the power consumption information and / or the cooling capacity information. Specifically, the electric-liquid integrated distribution module 200 can calculate the heating value by collecting the power consumption information of the parts to be cooled at each node, or calculate the heating value of the corresponding parts to be cooled by collecting the cooling capacity information of each two-phase cold plate 100 (for example, the flow rate of each liquid supply branch), or calculate the heating value of the corresponding parts to be cooled according to the power consumption information and the cooling capacity information at the same time, and then control the flow rate of each liquid supply branch of the two-phase cold plate 100 according to the heating value, so that the liquid fluid enters the two-phase cold plate 100 to absorb heat and immediately undergoes phase change and vaporizes into a vapor fluid.

[0085] Furthermore, in order to further improve the fluid phase change heat dissipation effect, the liquid cooling heat exchange module 300 of the two-phase cold plate liquid cooling cabinet 10 of the present application adopts at least three-stage heat exchange units, so that the vapor fluid can undergo condensation, supercooling, reheating and other heat exchange processes. The two-phase cold plate liquid cooling cabinet 10 can operate under a stable system pressure while outputting a liquid fluid of a third preset temperature to the electro-hydraulic integrated distribution module 200 (wherein the third preset temperature includes but is not limited to the fluid saturation temperature and slightly lower than the fluid saturation temperature), thereby improving the phase change heat transfer efficiency of the two-phase cold plate 100 at each node.

[0086] Compared with the prior art, the two-phase cold plate liquid cooling cabinet 10 of the present application has the following three beneficial effects:

[0087] 1: The heat generation of each branch is collected in real time through the electro-hydraulic integrated distribution module 200, so as to realize real-time control of the heat dissipation of the two-phase cold plate 100 of each branch, so as to avoid dry burning of part of the two-phase cold plate 100 and no phase change in the two-phase cold plate 100.

[0088] 2: Effectively ensure stable overclocking of components to be cooled (especially high-power electronic components, CPU, GPU), and can adaptively control the core temperature fluctuation of high-power heating components such as chips within 1.5°C, thereby improving the operating stability and temperature uniformity of the server.

[0089] 3: The heat dissipation performance of the two-phase cold plate liquid cooling cabinet 10 is effectively improved, and the heat dissipation effect can be more than doubled compared to the existing liquid cooling cabinet without reheating.

[0093] The second heat exchange unit 320 is used to receive the first cooling fluid and cool it to a second cooling fluid with a second preset temperature;

[0094] The third heat exchange unit 330 is used to receive the second cooling fluid and reheat the second cooling fluid to a third cooling fluid of a third preset temperature;

[0095] Wherein, the second preset temperature is not lower than the third preset temperature.

[0096] Specifically, the two-phase cold plate liquid cooling cabinet 10 of this embodiment is provided with three-stage heat exchange units in series, so that the vapor fluid can undergo heat exchange processes such as condensation, supercooling, and reheating. The two-phase cold plate liquid cooling cabinet 10 can output a liquid fluid of a third preset temperature to the electric-liquid integrated distribution module 200 (wherein the third preset temperature includes but is not limited to the fluid saturation temperature, slightly lower than the fluid saturation temperature) while operating under a stable system pressure, so that the liquid fluid can undergo phase change vaporization once it flows through the two-phase cold plate 100 and exchanges heat with the element to be cooled, maximizing the use of the phase change latent heat of the fluid, and improving the phase change heat transfer efficiency of the two-phase cold plate 100 at each node. Experimental comparison shows that the heat exchange efficiency of the reheated liquid cooling cabinet can be more than doubled compared to the heat dissipation effect of the liquid cooling cabinet that has not been reheated, which can effectively improve the installed density of the two-phase cold plate liquid cooling cabinet 10 and reduce the power distribution power of the data center computer room; it can also directly achieve zero-carbon heating.

[0115] It should be noted that one of the two cooling self-regulating pumps 250 can be selected to work. For example, when the liquid cooling system is in a normal working state, the liquid cooling medium can flow into the two-phase cold plate 100 through one of the first fluid pipelines in sequence. At this time, the cooling self-regulating pump 250 corresponding to one of the first fluid pipelines works. When the cooling self-regulating pump 250 is damaged, that is, the liquid cooling system is in an abnormal alarm state, another first fluid pipeline and its corresponding cooling self-regulating pump 250 can be selected to perform liquid separation work.

The fluid separation unit can be set as a blocking component corresponding to the second fluid pipeline, and / or a spiral channel corresponding to the second fluid pipeline, and / or a separation membrane arranged between the two fluid outlets.

[0118] Specifically, the second distribution pipeline is provided with two fluid outlets, and the gas-liquid two-phase cooling medium flowing out of the multiple two-phase cold plates 100 is collected through the corresponding second fluid pipeline and flows into the second distribution pipeline body, and then separated by the fluid separation unit in the second distribution pipeline body. After separation, the gaseous cooling medium flows into the liquid-cooled heat exchange module 300 through one of the fluid outlets, and the liquid cooling medium flows into the liquid heat exchange module through the other fluid outlet. By providing a fluid separation unit in the second distribution pipeline body, the gas-liquid mixed cooling medium in the second distribution pipeline is diverted, and by providing two fluid outlets on the second distribution pipeline, the diverted gaseous cooling medium and liquid cooling medium flow into the liquid heat exchange module respectively, and the gas-liquid mixed cooling medium flowing out of the two-phase cold plate 100 is quickly separated, and the separated gaseous fluid and liquid fluid are connected to the liquid-cooled heat exchange module 200 through different pipelines.
