[0047] In the embodiments of the present disclosure, the user's authorization or consent is obtained before obtaining or collecting the user's personal information.

[0048] With the continuous development and progress of server chip technology and artificial intelligence technology, the power density of server chips such as CPU or GPU used in intelligent computing center servers continues to rise. In order to ensure the normal heat dissipation of chips, server cold plate liquid cooling technology has been developed. The high-power chips are liquid-cooled by circulating the coolant in the liquid cooling heat sink. The liquid-cooled server is installed on a traditional rack, connected to the main pipeline system on the liquid cooling room side through the rack, and the pipeline on the room side is connected to the secondary side of the coolant distribution unit (CDU, Coolant Distribution Unit) to form an indoor ring liquid supply system. The primary side of the CDU is connected to the outdoor heat dissipation equipment (such as cooling towers or dry coolers) through pipelines to form an external heat dissipation cycle; cold plate liquid cooling is usually used to solve 50%~80% of the heat dissipation of liquid-cooled server chips. The heat dissipation of other hardware such as network switches, memory, hard disks, etc. still relies on the deployment of the room air cooling environment in the room to solve, usually accounting for 20%~50%.

The air-cooling system and liquid-cooling system equipment are selected and designed according to a fixed air-liquid cooling ratio during the planning and design stage. The ratio of liquid cooling and air cooling inside the server will be different according to business needs. When the ratio of liquid cooling to air cooling changes, there is a risk that the originally planned computer room air conditioning environment and liquid cooling environment cannot adapt to the latest server deployment requirements, the flexibility of business applications is limited, and the air-cooling or liquid cooling system needs to be renovated on a large scale, resulting in increased investment costs in the short term.

[0086] Figure 2 The flowchart of the data center cooling method according to the embodiment of the present disclosure is schematically shown.

[0087] like Figure 2 As shown, the method includes: operation S210 to operation S230.

[0088] In operation S210, in response to the received working signal, the data center cooling system is started, the temperature of the cooling liquid returning from the cabinet module to the liquid cooling module is collected, and the temperature difference of the supply and return liquid in the liquid cooling module is calculated.

[0089] In operation S220, a temperature value of an air wall cooling unit in an air-cooling cooling module is collected.

[0090] In operation S230, when it is determined that the temperature difference or the temperature value is not within the set range, based on the preset cooling ratio of liquid cooling and air cooling, based on the interlocking control of the first regulating valve and the second regulating valve in the regulating valve combination module, the ratio of coolant provided to the air-cooled cooling module and the liquid-cooled cooling module is dynamically adjusted to achieve air-cooled and liquid-cooled mixed cooling of the cabinet module based on the preset cooling ratio of liquid cooling and air cooling, wherein the data center cooling system is obtained according to the above system.

[0092] According to the embodiments of the present disclosure, when the temperature difference between the supply liquid and the return liquid is not within the set range, or the wind wall cooling unit is not within the set range, it means that the liquid cooling ratio has changed significantly. Based on the preset liquid cooling and air cooling ratio, the first regulating valve and the second regulating valve in the regulating valve combination module can be interlocked and controlled to dynamically adjust the ratio of coolant provided to the air cooling module and the liquid cooling module, so as to achieve the air cooling and liquid cooling mixed cooling of the cabinet module based on the preset liquid cooling and air cooling ratio, meet the deployment requirements of business scene changes, without the need for major air cooling, liquid cooling system architecture transformation or terminal equipment transformation, saving transformation investment and business deployment period caused by transformation. .

[0093] According to an embodiment of the present disclosure, for example, when the proportion of cold nights needs to be increased and the proportion of air cooling needs to be decreased, based on the calculated temperature difference between the supply liquid and the return liquid, if the temperature difference is not within the set temperature range where the proportion of cold nights needs to be increased and the proportion of air cooling needs to be decreased, the opening of the second regulating valve is increased, and at the same time, the opening of the first regulating valve is reduced in a chain reaction, so that a larger proportion of coolant is dynamically allocated to the liquid-cooled cooling module, and a smaller proportion of coolant is allocated to the air-cooled cooling module, thereby realizing dynamic adjustment of the cooling ratio of liquid cooling and air cooling, and realizing air-cooled and liquid-cooled mixed cooling of the cabinet servers in the cabinet module.

[0094] According to the embodiments of the present disclosure, when the CPU or GPU of the cabinet server in the cabinet module increases or decreases in real time due to changes in the business scenario, the supply and return liquid temperature difference of the liquid-cooled cooling module changes, and then the liquid-cooled cooling unit controls the liquid-cooled variable frequency circulation pump to increase or decrease the operating frequency of the water pump, thereby increasing the liquid-cooled supply and return liquid flow rate and increasing or decreasing the heat exchange capacity under the set supply and return liquid temperature difference. The water-fluorine heat exchange unit controls the variable frequency compressor through its own control system, and then the refrigerant circulation system realizes that the wind wall cooling unit controls its own fan speed to maintain the stability of the supply and return air temperature in the computer room channel. The first-side coolant flow of the liquid-cooled cooling module in the data center cooling system and the first-side coolant flow of the water-fluorine heat exchanger in the air-cooled cooling module are adaptively matched according to the overall control of the system.

[0095] According to the embodiments of the present disclosure, through the integrated regulation of the air-cooled cooling module and the liquid-cooled cooling module, the water-fluorine heat exchange unit and the wind wall refrigeration unit in the liquid-cooled cooling module and the air-cooled cooling module are integrated and applied in high-power density data center business or general computing business scenarios, so as to achieve high-elasticity, high-energy-efficiency, high-quality rapid prefabricated delivery of data center infrastructure, greatly reduce the investment and transformation cycle of the basic electromechanical system, and quickly respond to changing business situations.

[0096] The embodiments of the present disclosure are described above. However, these embodiments are only for illustrative purposes and are not intended to limit the scope of the present disclosure. Although the embodiments are described above, this does not mean that the measures in the various embodiments cannot be used in combination to advantage. Without departing from the scope of the present disclosure, those skilled in the art may make a variety of substitutions and modifications, which should all fall within the scope of the present disclosure.
