Description

Technical Field

[0001] This disclosure relates to the field of artificial intelligence technology, and in particular to the fields of cloud computing and chips, and especially to a cooling system, a control method for the cooling system, an apparatus, and an electronic device. Background Technology

[0002] Currently, in the field of artificial intelligence, there are two main types of air-to-liquid coolant distribution units (CDUs) used for cooling Graphics Processing Unit (GPU) servers: distributed air-to-liquid CDUs and cabinet-type air-to-liquid CDUs. Distributed air-to-liquid CDUs have weaker cooling capacity and are generally used to cool a single GPU server. Cabinet-type air-to-liquid CDUs have stronger cooling capacity and can be used to cool multiple GPU servers in a supernode rack.

[0003] As the power consumption of GPU servers gradually increases, their cooling requirements also increase. Distributed air-liquid CDUs are unable to meet the cooling needs of GPU servers, while cabinet-type air-liquid CDUs are too wasteful to use for a single GPU server, thus reducing cooling efficiency.

Detailed Implementation

[0014] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0015] Currently, in the field of artificial intelligence, there are two main types of air-to-liquid coolant distribution units (CDUs) used for cooling Graphics Processing Unit (GPU) servers: distributed air-to-liquid CDUs and cabinet-type air-to-liquid CDUs. Distributed air-to-liquid CDUs have weaker cooling capacity and are generally used to cool a single GPU server. Cabinet-type air-to-liquid CDUs have stronger cooling capacity and can be used to cool multiple GPU servers in a supernode rack.

[0016] As the power consumption of GPU servers gradually increases, their cooling requirements also increase. Distributed air-liquid CDUs are unable to meet the cooling needs of GPU servers, while cabinet-type air-liquid CDUs are too wasteful to use for a single GPU server, thus reducing cooling efficiency.

[0017] To address the aforementioned issues, this disclosure proposes a cooling system, a control method for the cooling system, an apparatus, and electronic equipment.

[0018] Figure 1 This is a schematic diagram based on the first embodiment of the present disclosure, as shown below. Figure 1 As shown, the cooling system may include: at least two air-liquid CDUs 101, a water distributor 102, and a liquid-cooled computing device 103; the water distributor 102 includes a liquid supply distributor 1021 and a liquid return distributor 1022.

[0019] Among them, at least two air-liquid CDU101 are used to transmit the supplied coolant to the liquid-cooled computing device 103 through the supply coolant distributor 1021, and to receive the coolant returned by the liquid-cooled computing device 103 through the return coolant distributor 1022.

[0020] In one embodiment of this disclosure, at least two air-fluid CDUs may be identical air-fluid CDUs. "At least two air-fluid CDUs are identical" can mean that at least two air-fluid CDUs have the same cooling capacity; or, it can mean that at least two air-fluid CDUs have the same structure. At least two air-fluid CDUs with the same structure have the same cooling capacity.

[0021] Among them, at least two air-fluid CDUs are the same air-fluid CDUs, which increases the probability that the control parameters of at least two air-fluid CDUs are the same, thereby reducing the amount of calculation of the control parameters of at least two air-fluid CDUs and reducing the control complexity of at least two air-fluid CDUs.

[0022] In another example, at least two air-fluid CDUs can be different air-fluid CDUs. Here, "at least two air-fluid CDUs are different" can mean that at least two air-fluid CDUs have different cooling capacities; or, in other words, that at least two air-fluid CDUs have different structures.

[0023] Where at least two air-hydraulic CDUs can be different air-hydraulic CDUs, the control parameters of at least two air-hydraulic CDUs can be different. These control parameters include, for example, circulation pump control parameters and fan control parameters.

[0024] In this embodiment of the disclosure, the number of air-liquid CDUs in the cooling system is determined based on the cooling capacity of the air-liquid CDUs and the cooling requirements of the liquid-cooled computing device. The cooling capacity of the air-liquid CDUs indicates their maximum cooling output.

[0025] Determining the number of air-liquid CDUs in the cooling system based on the cooling capacity of the air-liquid CDUs and the cooling requirements of the liquid-cooled computing equipment ensures that the cooling capacity of at least two air-liquid CDUs matches the cooling requirements of the liquid-cooled computing equipment. This avoids wasting cooling capacity and rack space resources used to house the air-liquid CDUs, thereby improving cooling efficiency and rack space utilization efficiency.

[0026] In this embodiment of the disclosure, in order to further expand the applicable scenarios of the cooling system and enable the cooling system to be used to cool liquid-cooled computing devices in more scenarios, thereby further improving the cooling efficiency, the liquid-cooled computing device 103 includes at least one of liquid-cooled servers and liquid-cooled cabinets; the liquid-cooled cabinet is provided with multiple liquid-cooled servers.

[0027] The liquid-cooled server mentioned here can be any liquid-cooled server with any number of GPU cards. Examples of liquid-cooled servers include 8-card GPU liquid-cooled servers and 16-card GPU liquid-cooled servers. It should be noted that a liquid-cooled server can refer to a server where the chips are surrounded by cold plates that transfer coolant.

[0028] In this embodiment of the disclosure, in order to ensure that the coolant can be circulated through the supply and return coolant distributors to further improve the cooling efficiency, such as... Figure 2 As shown. Figure 2 This is a schematic diagram of a cooling system. Figure 2In this context, we assume the liquid-cooled computing equipment is a supernode cabinet, i.e., a liquid-cooled cabinet. Figure 2 In the liquid supply distributor 1021, there are at least two liquid inlets 10211 and at least one liquid outlet 10212; the at least two liquid inlets are connected one-to-one with the liquid supply ports of at least two air-liquid CDUs; the at least one liquid outlet is connected one-to-one with at least one liquid inlet of the liquid-cooled computing device; the return liquid distributor 1022 is provided with at least one liquid inlet 10221 and at least two liquid outlets 10222; the at least one liquid inlet is connected one-to-one with at least one liquid outlet of the liquid-cooled computing device; the at least one liquid outlet is connected one-to-one with the return liquid port of at least two air-liquid CDUs.

[0029] Among them, Figure 2 In the diagram, the blue pipes represent the supply distributor; the red pipes represent the return distributor.

[0030] Each air-liquid CDU is equipped with one supply port and one return port. Within the air-liquid CDU, a circulating pump drives the coolant, delivering it through the supply port and supply distributor to the liquid-cooled computing equipment. Coolant returning from the liquid-cooled computing equipment enters the air-liquid heat exchanger within the air-liquid CDU. A powerful fan at the back of the air-liquid CDU operates at high speed, blowing cool air across the air-liquid heat exchanger to achieve heat exchange.

[0031] In this embodiment of the disclosure, the liquid-cooled server in the liquid-cooled computing device 103 is provided with a cold plate. The cold plate is disposed around the chip in the liquid-cooled server that has a cooling requirement and is used to cool the chip. The pipe in the cold plate is connected to an inlet and an outlet of the liquid-cooled server and is used to transfer coolant.

[0032] Among them, liquid-cooled servers contain chips that require cooling, such as GPU chips and central processing unit (CPU) chips. There are no specific limitations here, and the configuration can be set according to actual needs.

[0033] In a liquid-cooled server, the number of chips requiring cooling can be one or more. For example, for an 8-GPU liquid-cooled server, the chips requiring cooling could be, for example, 8 GPU chips. For a 16-GPU liquid-cooled server, the chips requiring cooling could be, for example, 16 GPU chips, and so on.

[0034] In this system, each cold plate has pipes that connect to one inlet and one outlet of the liquid-cooled server for coolant transfer. In one example, the inlet and outlet of pipes in different cold plates can be different. For instance, each cold plate may have a dedicated inlet and outlet for its pipes. In another example, the inlet and outlet of pipes in different cold plates can be the same. For instance, pipes in multiple cold plates may share the same inlet and outlet.

[0035] Each cold plate has a pipe that connects to an inlet and an outlet of the liquid-cooled server, allowing coolant to be transferred to the cold plate to cool the chips around it, thereby improving cooling efficiency.

[0036] In this embodiment of the disclosure, to facilitate cooling control processing of at least two air-liquid CDUs and improve cooling control efficiency, thereby further improving cooling efficiency, the cooling system may also include a control component 104. The control component 104 is communicatively connected to at least two air-liquid CDUs 101 and a liquid-cooled computing device 103, respectively; the control component 104 is used to determine the cooling parameters of at least two air-liquid CDUs according to the cooling requirements of the liquid-cooled computing device.

[0037] In embodiments of this disclosure, the control component may include at least one of a Baseboard Management Controller (BMC) and a switch. In one example, the control component may include a BMC component. In another example, the control component may include a switch.

[0038] Among them, such as Figure 3 As shown. Figure 3 This is another schematic diagram of a cooling system. Figure 3 In this context, we assume that control component 104 is a BMC component or a switch; and that the liquid-cooled computing device is a supernode cabinet, i.e., a liquid-cooled cabinet. Figure 3 In this system, the BMC component or switch can communicate with the liquid-cooled computing device via an RS485 cable; the BMC component or switch can also communicate with at least two air-liquid CDUs via an RS485 cable.

[0039] The inclusion of at least one of a Baseboard Management Controller (BMC) and a switch allows for flexible selection of at least one of the BMC and the switch as the control component according to actual needs, thereby improving the flexibility of control component selection.

[0040] In this embodiment of the disclosure, when at least two CDUs have the same cooling capacity or the same structure, in order to further improve the control efficiency of at least two air-fluid CDUs and enable at least two air-fluid CDUs to determine control parameters and perform cooling control processing in a timely manner according to the cooling parameters, at least two air-fluid CDUs can be communicatively connected to transmit the control parameters of the master air-fluid CDU to the slave air-fluid CDU; the control parameters are used to control the circulation pump and fan in at least two air-fluid CDUs; the master air-fluid CDU is the first air-fluid CDU with the control parameters set among at least one air-fluid CDU.

[0041] Among these are control parameters, such as circulating pump control parameters and fan control parameters.

[0042] This application provides a cooling system including: at least two air-liquid CDUs, a coolant distributor, and a liquid-cooled computing device; the coolant distributor includes a supply coolant distributor and a return coolant distributor; the at least two air-liquid CDUs are used to transfer supplied coolant to the liquid-cooled computing device through the supply coolant distributor, and to receive coolant returned from the liquid-cooled computing device through the return coolant distributor. By setting a coolant distributor between the at least two air-liquid CDUs and the liquid-cooled computing device, the number of air-liquid CDUs or CDUs connected to the distributor can be flexibly adjusted according to the cooling needs of the liquid-cooled computing device; as the power consumption of liquid-cooled servers gradually increases, the cooling demand and cooling capacity can be matched by adjusting the number of air-liquid CDUs, avoiding waste of cooling capacity and thus improving cooling efficiency.

[0043] Figure 4 The diagram is based on the second embodiment of the present disclosure. It should be noted that the control method of the cooling system in the present disclosure can be applied to the control device of the cooling system. The device can be configured in an electronic device so that the electronic device can perform the control function of the cooling system.

[0044] The electronic device can be any device with computing capabilities, such as a personal computer (PC), mobile terminal, or server. Mobile terminals can include in-vehicle devices, mobile phones, tablets, personal digital assistants, wearable devices, smart speakers, servers, server clusters, and other hardware devices with various operating systems, touchscreens, and / or displays. The electronic device can also be a device that communicates with the air-liquid CDU and liquid-cooled computing devices in the cooling system. Furthermore, the electronic device can be a control component located in the cooling system. This control component can communicate with the air-liquid CDU and liquid-cooled computing devices in the cooling system.

[0045] The control device for the cooling system can also be software within an electronic device, such as control software for the cooling system. In the following embodiments, the example will be a control component located within the cooling system.

[0046] like Figure 1 As shown, the control method for this cooling system may include the following steps: Step 401: Obtain the cooling requirements of the liquid-cooled computing equipment in the cooling system.

[0047] Cooling requirements can be expressed in terms of power, for example. Taking a liquid-cooled computing device as an example, the cooling requirement of a liquid-cooled server could be 10-30 kW. The cooling capacity of the air-cooled CDU in the cooling system can also be expressed in terms of power.

[0048] Step 402: Determine the cooling parameters for at least two air-liquid CDUs in the cooling system based on the cooling demand.

[0049] In this embodiment of the disclosure, the process of the control component executing step 402 may, for example, be as follows: determining the total cooling parameters according to the cooling demand; the total cooling parameters include: total cooling temperature, total cooling flow rate, and total cooling pressure; determining the cooling flow rate of a single air-liquid CDU according to the number of air-liquid CDUs and the total cooling flow rate; determining the cooling pressure of a single air-liquid CDU according to the number of air-liquid CDUs, the total cooling pressure, and the attribute parameters of the water distributor in the cooling system; and determining the total cooling temperature as the cooling temperature of a single air-liquid CDU.

[0050] In cases where multiple air-fluid CDUs are identical, combining the above steps can quickly determine the cooling parameters of each air-fluid CDU, thereby improving the speed of determining the cooling parameters of each air-fluid CDU.

[0051] Step 403: Send cooling commands carrying cooling parameters to at least two air-liquid CDUs to control at least two air-liquid CDUs to provide cooling to the liquid-cooled computing device.

[0052] Among them, at least two air-liquid CDUs can determine control parameters based on the cooling parameters carried in the cooling command after receiving the cooling command, and then perform cooling treatment according to the control parameters.

[0053] The control method of the cooling system in this embodiment obtains the cooling demand of the liquid-cooled computing device in the cooling system; determines the cooling parameters for at least two air-liquid CDUs in the cooling system based on the cooling demand; and sends cooling commands carrying the cooling parameters to the at least two air-liquid CDUs to control the at least two air-liquid CDUs to provide cooling to the liquid-cooled computing device. By combining the cooling system and the cooling parameters of the at least two air-liquid CDUs, the cooling of the liquid-cooled computing device in the cooling system can be achieved, matching the cooling capacity of the at least two air-liquid CDUs with the cooling demand of the liquid-cooled computing device, avoiding waste of cooling capacity, and thus improving cooling efficiency.

[0054] To achieve the above embodiments, this disclosure also provides a control device for a cooling system. For example... Figure 5 As shown, Figure 5 This is a schematic diagram according to a third embodiment of the present disclosure. The control device 50 of the cooling system may include: an acquisition module 501, a determination module 502, and a sending module 503.

[0055] The acquisition module 501 is used to acquire the cooling requirements of the liquid-cooled computing device; the determination module 502 is used to determine the cooling parameters for the at least two air-liquid CDUs based on the cooling requirements; and the sending module 503 is used to send a cooling command carrying the cooling parameters to the at least two air-liquid CDUs to control the at least two air-liquid CDUs to perform cooling processing on the liquid-cooled computing device.

[0056] As one possible implementation of this disclosure, the determining module 502 is specifically used to: determine the total cooling parameters based on the cooling demand; the total cooling parameters include: total cooling temperature, total cooling flow rate, and total cooling pressure; determine the cooling flow rate of a single air-liquid CDU based on the number of air-liquid CDUs and the total cooling flow rate; determine the cooling pressure of a single air-liquid CDU based on the number of air-liquid CDUs, the total cooling pressure, and the attribute parameters of the water distributor in the cooling system; and determine the total cooling temperature as the cooling temperature of a single air-liquid CDU.

[0057] The control device of the cooling system in this embodiment acquires the cooling demand of the liquid-cooled computing device in the cooling system; determines the cooling parameters for at least two air-liquid CDUs in the cooling system based on the cooling demand; and sends cooling commands carrying the cooling parameters to the at least two air-liquid CDUs to control the at least two air-liquid CDUs to provide cooling to the liquid-cooled computing device. By combining the cooling system and the cooling parameters of the at least two air-liquid CDUs, the cooling of the liquid-cooled computing device in the cooling system can be achieved, matching the cooling capacity of the at least two air-liquid CDUs with the cooling demand of the liquid-cooled computing device, avoiding waste of cooling capacity, and thus improving cooling efficiency.
