However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present application, so the present application is not limited by the specific implementation disclosed below.

[0042] Servers are an important part of electronic devices and are mainly used to provide computing services. According to the types of services provided by the server, they are mainly divided into storage servers, file servers, database servers, application servers, web servers, etc. The main components of the server include the motherboard, processor, hard disk, memory, etc., which are similar to the general computer architecture.

[0043] In the era of big data, a large number of information technology equipment will be concentrated in data centers. These data centers contain various types of servers, storage, switches, a large number of cabinets 10 and other infrastructure. Traditional data centers use air cooling, but their energy utilization rate is low and does not meet the requirements of green development of the information industry. And when large data centers with high power density gradually become mainstream, conventional air cooling has been difficult to meet the ultra-high heat dissipation requirements of data centers due to their low heat dissipation limit.

[0044] Therefore, how to improve energy utilization and meet the heat dissipation needs of data centers has become an urgent problem to be solved by technical personnel in this field.

[0045] The present application is described in detail below through multiple embodiments and drawings.

[0046] First embodiment

[0047] The first embodiment of the present application provides a gas-liquid mixed cooling system as follows: Figure 1 The gas-liquid mixed cooling system is described in detail. Figure 1 It is a schematic diagram of a gas-liquid mixed cooling system provided in the first embodiment of the present application.

[0048] In this embodiment, the gas-liquid mixed cooling system includes: a plurality of cabinets 10, a cooling module 20 and a control module 30, wherein each cabinet 10 is provided with a heat source component, and the heat source component may include a motherboard, a processor, a hard disk, a memory, etc. The cooling module 20 includes at least a cooling plate and an air cooling device, wherein the cooling plate may contact the heat source component for heat exchange with the heat source component. The air cooling device is provided between the air outlet of the cabinet 10 and the heat source component, and is used to generate airflow to the heat source component and the air outlet. The control module 30 is used to obtain the first temperature information of the heat source component in each cabinet 10 and the second temperature information of the corresponding cooling plate, and control the temperature and flow rate of the coolant in each cooling plate according to the first temperature information and the second temperature information, and / or control the rotation speed of each air cooling device according to the first temperature information and the second temperature information.

[0049] Specifically, in this embodiment, the cabinet 10 is an important part of the data center and the data supercomputing center, and multiple cabinets 10 are provided in the data center and the data supercomputing center. A heat source component may be installed in each cabinet 10, and the heat source component may include various components such as a motherboard, a processor, a hard disk, a memory, a computing software, a power supply, or a combination of several of the above components. In one example, the cabinet 10 can be set as a vertical cube structure, and a corresponding accommodation position for the heat source component is provided in the cabinet 10, and the heat source component is installed in the accommodation position accordingly. In one example, the front of the cabinet 10 is used for access to the heat source component, and the rear is used for wiring and pipelines. The front and rear parts of the cabinet 10 are arranged with a power supply unit and a data connection port to facilitate the power supply and data communication of the heat source component. The power supply unit is designed with a variety of redundancy and protection mechanisms to ensure stable operation of the system. The top or bottom of the cabinet 10 is provided with an interface for the entry and exit of the coolant. The internal space of the cabinet 10 is fully utilized to adapt to the installation and maintenance of the multi-cold plate structure. When the heat source component is working, it will generate a lot of heat, which will increase the temperature of the heat source component. This will not only affect the operating efficiency of the heat source component, but also cause application safety problems.

[0050] In this regard, the present embodiment is provided with a cooling module 20 in each cabinet 10, wherein the cooling module 20 includes at least a cooling plate and an air cooling device, and the cooling plate can contact the heat source component for heat exchange with the heat source component. In one example, the cooling plate is arranged above the heat source component, or the cooling plate is arranged below the heat source component, or the cooling plate is arranged at a relative position where the heat source component can have the largest contact area, so that the cooling plate can directly contact the heat source component to maximize heat conduction. In addition, microchannel technology is used inside the cooling plate to increase the contact area between the coolant and the cooling plate and enhance the heat exchange efficiency. In one example, the microchannel technology includes a multi-channel, that is, multiple channels are arranged inside the cooling plate, and the increase in channels can increase the contact area between the coolant and the cooling plate, thereby enhancing the heat exchange efficiency. In one example, the cooling pipe is made of a material with high thermal conductivity, such as copper or aluminum, or a graphene composite material, to ensure effective heat transfer.

[0051] In the present embodiment, the coolant in the cooling plate is a circulatory coolant to maintain the coolant in the cooling plate at a low temperature. In the present embodiment, in order to realize the circulation of the coolant in the cooling plate, the cooling module 20 also includes a cold liquid circulation module, wherein the cold liquid circulation module includes a liquid cooling pipeline, a pump body and a guide valve, and the cold liquid circulation module is connected to each cooling plate through a liquid cooling pipeline to transport the coolant in the cold liquid circulation module to the cooling plate. The liquid cooling pipeline includes a coolant output pipeline and a coolant return pipeline, the coolant output pipeline transports the coolant to the cooling plate, and the coolant return pipeline returns the coolant that has absorbed heat to the coolant accommodating cavity in the cold liquid circulation module. The coolant output pipeline, the cooling plate, the coolant return pipeline and the coolant accommodating cavity constitute a complete closed-loop coolant circulation system.

[0052] In one example, the coolant can be used as the refrigerant of the liquid-cooled server, that is, the coolant is directly provided to the liquid-cooled server as the refrigerant of the liquid-cooled server to cool the liquid-cooled server. In one example, the coolant of this embodiment can also be used in an air-cooled server, that is, the air-cooled server is cooled by a cooling plate.

[0053] In addition, in order to reasonably control the flow of the circulating coolant, the control module 30 controls the pump body and the guide valve in the cold liquid circulation module to deliver the circulating coolant to the corresponding cooling plate according to the first temperature information and the second temperature information. Specifically, the heat source component will generate heat during operation, that is, it will correspond to the first temperature information. After the coolant absorbs the heat of the cooling plate, the temperature of the cooling plate will also change, that is, it will correspond to the second temperature information. The control module 30 controls the pump body and the guide valve in the cold liquid circulation module to deliver the circulating coolant to the corresponding cooling plate according to the first temperature information and the second temperature information.

[0054] In this embodiment, the cold liquid circulation module also includes a steam drainage pipe and a condensation channel, wherein the steam drainage pipe is connected to the steam chamber of the cooling plate, and the condensation channel is connected to the steam drainage pipe and the coolant return pipe of the liquid cooling pipeline, which is used to draw out the coolant vapor formed after the coolant in the cooling plate absorbs heat and changes phase, and condenses the coolant vapor through the condensation channel and flows back to the liquid cooling pipeline. Specifically, the coolant in the cooling plate absorbs the heat of the heat source component and changes phase to form coolant vapor. The coolant vapor will contact the condensation channel during the rising process, and then be condensed by the condensation medium, and then flow back to the coolant return pipe after the phase change to form liquid coolant, thereby realizing the recycling of the coolant.

[0055] In this embodiment, the cooling liquid circulation module further includes: a purifier disposed on the steam drainage pipe to filter impurities from the two-phase cooling liquid formed by condensation.

[0056] In this embodiment, the air cooling device is arranged between the air outlet of the cabinet 10 and the heat source component, and is used to generate airflow to the heat source component and the air outlet. Specifically, the air cooling device includes a radiator and a fan, wherein the radiator is connected to the heat source component and is used to dissipate heat from the heat source component. The fan is arranged at the air outlet of the cabinet 10, and is used to generate airflow to the radiator and the air outlet, thereby leading the heat out of the cabinet 10, and reducing the overall temperature of the cabinet 10.

[0057] In one example, corresponding to the coolant vapor generated above, part of the coolant vapor is condensed by the condensation channel to form coolant, and the rest is converted by the driving mechanism of the fan or radiator into kinetic energy for driving the fan or radiator, thereby driving the fan or radiator to rotate. Since the rotational force of the fan or radiator comes from the coolant vapor, and the energy of the coolant vapor comes from the heat generated by the heat source components running in each cabinet 10, this embodiment reasonably utilizes the heat of the heat source components as kinetic energy, and there is no need to install additional components such as drive motors to drive the fan or radiator, nor is there any need to consume electricity to process the heat of the server through other refrigeration equipment. On the basis of achieving normal condensation of the two-phase coolant, it can reduce system energy consumption and improve energy utilization.

[0058] In one example, a fan can be disposed on the top of the cabinet 10. The fan on the top of the cabinet 10 assists cooling under low heat load conditions, reducing the work intensity of the pump body that transports the coolant, thereby saving energy. In addition, the speed of the fan can be automatically adjusted according to the temperature inside the system, maintaining uniform airflow circulation inside the cabinet 10, which helps maintain a balanced temperature of the components.

[0059] In this embodiment, in order to accurately obtain the first temperature information of the heat source component and the second temperature information of the cooling plate, it also includes: a detection module, the detection module is arranged in the cabinet 10, and is used to detect the first temperature information of the heat source component and the second temperature information of the cooling plate, and detect the flow information and flow rate information of the coolant circulating in the cold liquid circulation module, and feed back the first temperature information, the second temperature information, the flow information and the flow rate information to the control module 30.

[0060] In this embodiment, the control module 30 is a central cooling capacity distribution module, and the control module 30 is used to obtain the first temperature information of the heat source component in each cabinet 10 and the second temperature information of the corresponding cooling plate, and control the temperature and flow rate of the coolant in each cooling plate according to the first temperature information and the second temperature information, and / or control the speed of each air cooling device according to the first temperature information and the second temperature information. Specifically, controlling the temperature and flow rate of the coolant in the cooling plate according to the first temperature information and the second temperature information, and / or controlling the speed of the air cooling device according to the first temperature information and the second temperature information, includes the following specific steps:

[0061] First, obtain the correspondence between the preset temperature information and the heat dissipation mode, wherein the preset temperature information at least includes the temperature information of the heat source component and the temperature information of the cooling plate, and the heat dissipation mode includes liquid cooling, air cooling, and a combination of liquid cooling and air cooling. In one example, in order to determine the correspondence between the preset temperature information and the heat dissipation mode, a large amount of temperature information of the heat source component and the temperature information of the cooling plate can be obtained first, and the correspondence between the temperature information of the heat source component, the temperature information of the cooling plate and the heat dissipation mode can be established. For example, if the temperature information of the heat source component is 10-30 degrees and the temperature information of the cooling plate is minus 5-0 degrees, the corresponding heat dissipation mode is air cooling; if the temperature information of the heat source component is 30-50 degrees and the temperature information of the cooling plate is 0-10 degrees, the corresponding heat dissipation mode is liquid cooling; if the temperature information of the heat source component is 50-70 degrees and the temperature information of the cooling plate is 10-15 degrees, the corresponding heat dissipation mode is a combination of liquid cooling and air cooling. After determining the correspondence between the preset temperature information and the heat dissipation mode, match the first temperature information and the second temperature information with the preset temperature information, and determine the target heat dissipation mode according to the correspondence between the preset temperature information and the heat dissipation mode. Finally, the temperature and flow rate of the coolant in the cooling plate are controlled according to the target heat dissipation mode, and / or the rotation speed of the air cooling device is controlled. For example, if the target heat dissipation mode is air cooling, the rotation speed of the air cooling device is controlled, and the pump body driving the coolant does not work; if the target heat dissipation mode is liquid cooling, the pump body driving the coolant is controlled to adjust the temperature and flow rate of the coolant in the cooling plate. If the target heat dissipation mode is a combination of liquid cooling and air cooling, the pump body driving the coolant is controlled to adjust the temperature and flow rate of the coolant in the cooling plate, and the rotation speed of the air cooling device is controlled. In this embodiment, the temperature and flow rate of the coolant, and the rotation speed of the air cooling device can be determined according to the first temperature information and the second temperature information.

[0062] Furthermore, in one example, the temperature and flow rate of the coolant in the cooling plate can be controlled according to the first temperature information, the second temperature information, the flow rate information, and the flow rate information, and / or the speed of the air cooling device can be controlled according to the first temperature information, the second temperature information, the flow rate information, and the flow rate information. The multi-dimensional information participation enables the control module 30 to predict the change of the thermal load of the system, automatically adjust the cooling strategy, and ensure that the system always operates in the best state.

[0063] The first embodiment of the present application provides a gas-liquid mixed cooling system, comprising: a plurality of cabinets 10, each of which is provided with a heat source component; a cooling module 20, comprising at least a cooling plate and an air cooling device, the cooling plate being in contact with the heat source component for performing heat exchange on the heat source component; the air cooling device being disposed between an air outlet of the cabinet 10 and the heat source component for generating an airflow to the heat source component and the air outlet; a control module 30, for obtaining first temperature information of the heat source component in each cabinet 10 and second temperature information of the corresponding cooling plate, controlling the temperature and flow rate of the coolant in each cooling plate according to the first temperature information and the second temperature information, and / or controlling the rotation speed of each air cooling device according to the first temperature information and the second temperature information.

[0064] The embodiment of the present application sets the cooling plate and the air cooling device at a position where they can directly contact the heat source components in the cabinet 10, so that the cooling plate and the air cooling device can directly cool down the heat source components in the individual cabinets 10. Moreover, the control module 30 can timely obtain the first temperature information of the heat source components in each cabinet 10 and the second temperature information of the corresponding cooling plate, and control the temperature and flow rate of the coolant in each cooling plate according to the first temperature information and the second temperature information, and / or control the rotation speed of each air cooling device according to the first temperature information and the second temperature information, so as to realize the reasonable operation of each cooling plate and each air cooling device, so as to ensure the accurate cooling down of the heat source components in the corresponding cabinet 10, thereby improving the energy utilization rate while meeting the heat dissipation requirements of the data center.

[0065] Second embodiment

[0066] In the above-mentioned first embodiment, a gas-liquid mixed cooling system is provided. Correspondingly, the second embodiment of the present application provides a gas-liquid mixed cooling method. The parts of this embodiment that are the same as those of the first embodiment will not be repeated here. Please refer to the corresponding parts in the first embodiment.

[0067] Please refer to Figure 2 , Figure 2 This is a flow chart of a gas-liquid mixed cooling method provided in the second embodiment of the present application.

[0068] Step S201: Obtain device information of a target cabinet.

[0069] The target cabinet is one of many cabinets in a data center or a data supercomputing center. In a data center or a data supercomputing center, each cabinet has corresponding equipment information, and the equipment information may include a cabinet number.

[0070] Step S202: acquiring first temperature information of a heat source component in the target cabinet and second temperature information of a corresponding cooling plate according to the device information of the target cabinet.

[0071] In this step, after the target cabinet is determined, the first temperature information of the heat source component in the target cabinet and the second temperature information of the corresponding cooling plate can be obtained. The first temperature information of the heat source component and the second temperature information of the cooling plate are detected by the detection module, and the first temperature information of the heat source component and the second temperature information of the cooling plate are fed back to the control module. In this embodiment, the heat source component may include various components such as a mainboard, a processor, a hard disk, a memory, a computing software, a power supply, or a combination of several of the above components.

[0072] Step S203: controlling the temperature and flow rate of the coolant in the cooling plate according to the first temperature information and the second temperature information, and / or controlling the rotation speed of the air cooling device according to the first temperature information and the second temperature information.

[0073] In this step, the air cooling device is also a device for cooling the heat source components in the cabinet. The air cooling device and the cooling plate in the cooling module cool the heat source components in the cabinet together. The air cooling device and the cooling plate cooperate with each other to make energy use reasonable, thereby improving energy utilization efficiency.

[0074] This step specifically includes the following steps: obtaining a correspondence between preset temperature information and a heat dissipation method, wherein the preset temperature information includes at least the temperature information of the heat source component and the temperature information of the cooling plate, and the heat dissipation method includes a liquid cooling method, an air cooling method, and a combination of liquid cooling and air cooling. In one example, in order to determine the correspondence between the preset temperature information and the heat dissipation method, a large amount of temperature information of the heat source component and the temperature information of the cooling plate can be first obtained, and a correspondence between the temperature information of the heat source component, the temperature information of the cooling plate and the heat dissipation method is established. For example, if the temperature information of the heat source component is 10-30 degrees and the temperature information of the cooling plate is minus 5-0 degrees, the corresponding heat dissipation method is air cooling; if the temperature information of the heat source component is 30-50 degrees and the temperature information of the cooling plate is 0-10 degrees, the corresponding heat dissipation method is liquid cooling; if the temperature information of the heat source component is 50-70 degrees and the temperature information of the cooling plate is 10-15 degrees, the corresponding heat dissipation method is a combination of liquid cooling and air cooling. After determining the correspondence between the preset temperature information and the heat dissipation mode, match the first temperature information and the second temperature information with the preset temperature information, and determine the target heat dissipation mode according to the correspondence between the preset temperature information and the heat dissipation mode. Finally, the temperature and flow rate of the coolant in the cooling plate are controlled according to the target heat dissipation mode, and / or the rotation speed of the air cooling device is controlled. For example, if the target heat dissipation mode is air cooling, the rotation speed of the air cooling device is controlled, and the pump body driving the coolant does not work; if the target heat dissipation mode is liquid cooling, the pump body driving the coolant is controlled to adjust the temperature and flow rate of the coolant in the cooling plate. If the target heat dissipation mode is a combination of liquid cooling and air cooling, the pump body driving the coolant is controlled to adjust the temperature and flow rate of the coolant in the cooling plate, and the rotation speed of the air cooling device is controlled. In this embodiment, the temperature and flow rate of the coolant, and the rotation speed of the air cooling device can be determined according to the first temperature information and the second temperature information.

[0075] Furthermore, in one example, the temperature and flow rate of the coolant in the cooling plate can be controlled according to the first temperature information, the second temperature information, the flow rate information, and the flow rate information, and / or the speed of the air cooling device can be controlled according to the first temperature information, the second temperature information, the flow rate information, and the flow rate information. The multi-dimensional information participation enables the control module to predict the thermal load changes of the system, automatically adjust the cooling strategy, and ensure that the system always operates in the best state.

[0076] The present embodiment provides a gas-liquid mixed cooling method, which achieves reasonable operation of each cooling plate and each air cooling device by obtaining first temperature information of a heat source component in each cabinet and second temperature information of a corresponding cooling plate, and controlling the temperature and flow rate of the coolant in each cooling plate according to the first temperature information and the second temperature information, and / or controlling the rotation speed of each air cooling device according to the first temperature information and the second temperature information, so as to ensure accurate cooling of the heat source components in the corresponding cabinet, thereby improving energy utilization while meeting the heat dissipation needs of the data center.
