[0036] In order to enable those skilled in the art to better understand the solution of the present application, the following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, other embodiments obtained by ordinary technicians in the field without creative work are all within the scope of protection of this application.

[0037] As the core equipment for data processing and storage, the performance and stability of the server are crucial to the entire information system. However, with the improvement of server computing power and the increase of power density, heat dissipation has gradually become a key factor restricting the further improvement of server performance. Although traditional server heat dissipation solutions, such as air cooling, can meet the heat dissipation requirements to a certain extent, their heat dissipation effect gradually decreases in scenarios with high power density and high heat flux density, and cannot meet the heat dissipation requirements of modern servers.

[0038] Please refer to Figures 1 to 3 In view of the above problems, an embedded pump-driven two-phase liquid-cooled CDU system 10 is proposed in the first embodiment of the present application. CDU (Cooling Dispensing Unit) is used to distribute and regulate the refrigerant in and out of mechanical equipment or systems. The server is provided with a plurality of groups of processor chips and cold plates, the processor chips and cold plates are arranged in a one-to-one correspondence, the cold plates are arranged in contact with the processor chips, and the cold plates are used to perform heat exchange on the processor chips. The embedded pump-driven two-phase liquid-cooled CDU system 10 is arranged in the cabinet of the server and connected to the cold plate of the server.

[0039] The embedded pump-driven two-phase liquid-cooled CDU system 10 includes a condenser 11, a liquid storage tank 12, a control valve 13, a fluorine pump assembly 14 and a control assembly 15 connected in sequence; a plurality of the cold plates are connected in series between the condenser 11 and the fluorine pump assembly 14 in a parallel manner, and the fluorine pump assembly 14 includes a plurality of fluorine pumps 141 arranged in parallel, and the plurality of fluorine pumps 141 are used to drive the refrigerant to circulate between the plurality of the cold plates, the condenser 11, the liquid storage tank 12 and the control valve 13, and the control valve 13 is used to The control valve 13 is used to control the on / off of the liquid storage tank 12 and the fluorine pump assembly 14. The control valve 13 includes a mechanical valve or an electric valve. The control valve is also provided with a refrigerant filling port, through which refrigerant can be added to the embedded pump-driven two-phase liquid-cooled CDU system; when the embedded pump-driven two-phase liquid-cooled CDU system 10 is running, the control valve 13 is in an open state; the control assembly 15 is electrically connected to the condenser 11, the control valve 13 and the fluorine pump assembly 14; the control assembly 15 is used The control component 15 is used to control the opening and closing of the control valve 13. For example, when the embedded pump-driven two-phase liquid-cooled CDU system 10 stops running, or when the embedded pump-driven two-phase liquid-cooled CDU system 10 leaks refrigerant, the control component 15 controls the control valve 13 to close, thereby avoiding refrigerant leakage; the control component 15 is also used to control the speed of the cooling fan 112 of the condenser 11, thereby ensuring that the refrigerant flowing through the condenser 11 is cooled and liquefied as much as possible, thereby ensuring that the refrigerant in the liquid storage tank 12 is in a liquid state, and ensuring the safe operation of the fluorine pump component 14; the control component 15 is also used to control the alternating operation of a single fluorine pump 141 among multiple fluorine pumps 141 according to a preset time period, and the multiple fluorine pumps 141 are circulated, that is, one pump among the multiple pumps is running, and after running for a period of time, another pump is switched to run, and the multiple pumps are circulated to further improve the reliability of the system operation; at the same time, the control component 15 can also control the speed of the multiple fluorine pumps 141, thereby ensuring the cooling effect.

[0040] The liquid refrigerant in the liquid storage tank 12, under the action of the fluorine pump assembly 14, passes through the control valve 13 and enters the fluorine pump assembly 14. After flowing out of the fluorine pump assembly 14, it enters a plurality of parallel cold plates, absorbs the heat on the cold plates, and part of the liquid refrigerant absorbs heat and vaporizes. After the cold plate is cooled by the refrigerant, it can continue to absorb the heat of the processor, thereby cooling the processor. After flowing out of the cold plate, the refrigerant becomes a gas-liquid mixed state or a gaseous state, and then enters the condenser 11, is cooled and liquefied by the condenser 11, and finally returns to the liquid storage tank 12 again, and the next cycle process begins. It can be seen that the phase change process of the refrigerant's vaporization and heat absorption can absorb the heat of the cold plate and the processor more efficiently and quickly, and can omit large cold sources, cooling towers or chillers, effectively reducing costs and volume, and improving ease of use.

[0041] In some specific embodiments, the fluorine pump assembly 14 is provided with two fluorine pumps 141, which are respectively a first fluorine pump 141 and a second fluorine pump 141. When the working time of the first fluorine pump 141 reaches a first preset working time, the first fluorine pump 141 is controlled to stop working, and the second fluorine pump 141 is started to work. The timing starts when the second fluorine pump 141 starts to work. When the working time of the second fluorine pump 141 reaches a second preset working time, the second fluorine pump 141 is controlled to stop working, and the first fluorine pump 141 is started to work until the processor temperature of the server is cooled below the preset temperature.

[0042] In other specific embodiments, the fluorine pump assembly 14 is provided with three fluorine pumps 141, which are respectively a first fluorine pump 141, a second fluorine pump 141 and a third fluorine pump 141. When the working time of the first fluorine pump 141 reaches a first predetermined working time, the first fluorine pump 141 is controlled to stop working, and the second fluorine pump 141 is started to work. The timing starts when the second fluorine pump 141 starts to work. When the working time of the second fluorine pump 141 reaches a second preset working time, the second fluorine pump 141 is controlled to stop working, and the third fluorine pump 141 is started to work. The timing starts when the third fluorine pump 141 starts to work. When the working time of the third fluorine pump 141 reaches the third preset working time, the third fluorine pump 141 is controlled to stop working, and the first fluorine pump 141 is started to work until the processor temperature of the server is cooled below the preset temperature.

[0043] Furthermore, the control component 15 includes a patrol module 151, which is electrically connected to the multiple fluorine pumps 141, and is used to control the alternating operation of a single fluorine pump 141 among the multiple fluorine pumps 141 according to a preset time period, thereby effectively ensuring the practical life of the fluorine pump component 14 and improving the operating stability of the embedded pump-driven two-phase liquid-cooled CDU system 10.

[0044] In some embodiments, the embedded pump-driven two-phase liquid-cooled CDU system 10 further includes a filter 16, which is connected in series between the control valve 13 and the fluorine pump assembly 14, and is used to filter out impurities entering the refrigerant. During the processing and preparation of the embedded pump-driven two-phase liquid-cooled CDU system 10 and during daily use, it is inevitable that residual impurities, such as welding slag, metal debris, etc., will be mixed back into the refrigerant during the refrigerant circulation process; by setting up the filter 16, impurities entering the refrigerant can be filtered out, thereby effectively ensuring the service life of each component of the embedded pump-driven two-phase liquid-cooled CDU system 10.

[0045] Please refer to further Figures 3 to 6In some embodiments, the embedded pump-driven two-phase liquid-cooled CDU system 10 further includes a first stop valve 17 and a second stop valve 18. The first stop valve 17 is connected in series to the side of the fluorine pump assembly 14 close to the multiple cold plates; the second stop valve 18 is connected in series to the side of the condenser 11 close to the multiple cold plates. That is to say, after the refrigerant flows out of the fluorine pump assembly 14 and before entering the cold plate, it must pass through the first stop valve 17. By controlling the position of the first stop valve 17, the amount of refrigerant leakage can be further reduced and the connection with the cold plate can be facilitated; after the refrigerant flows out of the cold plate and before entering the condenser 11, it must pass through the second stop valve 18. By controlling the position of the second stop valve 18, the amount of refrigerant leakage can be further reduced and the connection with the cold plate can be facilitated.

[0046] In some embodiments, when the embedded pump-driven two-phase liquid-cooled CDU system 10 operates under ultra-low temperature conditions, when the inlet temperature of the cold plate is low, the refrigerant is prone to ice on the surface of the inlet pipe when circulating in the system, causing the inlet pipe to freeze and crack, making the system unable to work normally. In order to avoid such risks and improve the reliability of system operation; the embedded pump-driven two-phase liquid-cooled CDU system 10 also includes a first temperature-pressure integrated sensor 191 and a second temperature-pressure integrated sensor 192. The first temperature-pressure integrated sensor 191 is arranged between the first stop valve 17 and the fluorine pump assembly 14, and is used to detect the temperature and pressure of the refrigerant entering the cold plate; the second temperature-pressure integrated sensor 192 is arranged between the second stop valve 18 and the condenser 11, and is used to detect the temperature and pressure of the refrigerant flowing out of the cold plate. This provides data guarantee for controlling the rotation speed of the embedded pump-driven two-phase liquid-cooled CDU system 10.

[0047] Furthermore, the control component 15 also includes a speed control module 152, which is electrically connected to the first temperature-pressure integrated sensor 191, the second temperature-pressure integrated sensor 192 and the fluorine pump component 14. The speed control module 152 is used to adjust the speed of the fluorine pump component 14 according to the temperature data and pressure data detected by the first temperature-pressure integrated sensor 191 and the second temperature-pressure integrated sensor 192; the first temperature-pressure integrated sensor 191 and the second temperature-pressure integrated sensor 192 can both detect temperature and pressure at the same time, thereby providing a guarantee for the speed control module 152 to adjust the speed of the fluorine pump component 14, and by controlling the speed of the fluorine pump component 14, the refrigerant flow entering the cold plate is controlled.

[0048] Specifically, under ultra-low temperature conditions, when the pressure inside the liquid inlet pipe is less than or equal to the first set pressure, and the temperature inside the liquid inlet pipe is less than or equal to the first set temperature, the air volume of the cooling fan 112 of the condenser 11 is controlled to decrease. Under ultra-low temperature conditions, when the air volume of the cooling fan 112 of the condenser 11 decreases, the air volume blown by the cooling fan 112 to the condenser 11 body of the condenser 11 also decreases accordingly, thereby reducing the heat exchange between the refrigerant in the condenser body 111 and the low-temperature air outside. Accordingly, the temperature of the refrigerant in the condenser body 111 increases, which can reduce the freezing of the system pipeline and improve the reliability of the embedded pump-driven two-phase liquid-cooled CDU system 10.

[0049] In some embodiments, the condenser 11 includes a condenser body 111 and a cooling fan 112, wherein the condenser body 111 is connected in series between the second stop valve 18 and the fluorine pump assembly 14, and the cooling fan 112 is electrically connected to the speed control module 152, and the speed control module 152 is used to adjust the speed of the cooling fan 112 according to the temperature data and pressure data detected by the first temperature-pressure integrated sensor 191 and the second temperature-pressure integrated sensor 192. The cooling fan 112 dissipates heat and liquefies the gaseous refrigerant flowing through the condenser body 111, thereby ensuring that the refrigerant entering the fluorine pump assembly 14 is in a liquid state, thereby protecting the structural safety of the fluorine pump assembly 14.

[0050] In some embodiments, the embedded pump-driven two-phase liquid-cooled CDU system 10 also includes a shell 195, the shell 195 includes an electric control compartment 193 and a functional compartment 194, the condenser body 111, the liquid storage tank 12, the control valve 13 and the fluorine pump assembly 14 are all located in the functional compartment 194, and the control assembly 15 is arranged in the electric control compartment 193; the condenser body 111 is tilted from the functional compartment 194 toward the electric control compartment 193, thereby increasing the contact area and time between the radiator and the heat dissipation airflow, thereby improving the heat dissipation effect; the cooling fan 112 is arranged at one end of the functional compartment 194 away from the electric control compartment 193, which can effectively avoid the influence of the cooling fan 112 located in the compartment on the volume of the embedded pump-driven two-phase liquid-cooled CDU system 10, and can also avoid the vibration of the embedded pump-driven two-phase liquid-cooled CDU system 10 when the cooling fan 112 is running. It should be noted that the condenser 11, the liquid storage tank 12, the control valve 13, the filter 16, the fluorine pump assembly 14 and the first stop valve 17 of the embedded pump-driven two-phase liquid-cooled CDU system 10 are all connected by pipelines, a plurality of cold plates are connected in parallel between the first stop valve 17 and the second stop valve 18, and the second stop valve 18 and the condenser 11 are also connected by pipelines, thereby ensuring that the refrigerant circulates in a sealed manner in the embedded pump-driven two-phase liquid-cooled CDU system 10 and the cold plate.

[0051] Please refer to Figure 4 and Figure 5 In some embodiments, the control component 15 further includes a power switch 153, an alarm warning light 154, a signal quick plug 155, a power quick plug 156, a control screen 157, a fluorine pump driver 158, a transformer 159, a filter 15a and a terminal block 15b. The power quick plug 156, the power switch 153, the transformer 159, the filter 15a and the terminal block 15b are electrically connected in sequence, and the control screen 157 is electrically connected to the fluorine pump driver 158, the signal quick plug 155 and the alarm warning light 154; the fluorine pump driver 158 is electrically connected to the fluorine pump component 14. By setting the alarm warning light 154, the early warning information 154 can be issued in time, and by setting the control screen 157, the operation of the embedded pump-driven two-phase liquid-cooled CDU system 10 can be controlled. The embedded pump-driven two-phase liquid-cooled CDU system 10 is turned on by the power switch 153, and the communication connection between the embedded pump-driven two-phase liquid-cooled CDU system 10 and the external device is realized by connecting the signal quick plug 155.

[0052] A second embodiment of the present application proposes a server, which includes the embedded pump-driven two-phase liquid-cooled CDU system as described above, thereby improving the heat dissipation performance of the server, and reducing energy consumption and cost. For details, please refer to the first embodiment described above.

[0053] A server heat dissipation control method is proposed in the third embodiment of the present application. The server heat dissipation control is implemented based on the embedded pump-driven two-phase liquid cooling CDU system as described in the first embodiment of the present application. The server heat dissipation control method includes:

[0054] The control valve, the first stop valve, the second stop valve, the cooling fan and the fluorine pump assembly are turned on to drive the refrigerant to flow through the plurality of cold plates;

[0055] detecting a first temperature entering the cold plate, and a second temperature flowing out of the cold plate;

[0056] The rotation speeds of the cooling fan and the fluorine pump assembly are controlled according to the first temperature and the second temperature.

[0057] It can be seen that the embedded pump-driven two-phase liquid-cooled CDU system is embedded in the server when in use. By monitoring the temperature and pressure of the refrigerant entering and flowing out of the cold plate, the speed of the cooling fan and the fluorine pump assembly can be adjusted in real time, thereby ensuring that the embedded pump-driven two-phase liquid-cooled CDU system is in the best operating state.

[0058] In some embodiments, the control component starts the fluorine pump component to operate specifically including:

[0059] The control component controls each fluorine pump in the fluorine pump assembly to run for a preset time period one by one until the processor temperature is lower than a preset temperature threshold, and then shuts down the fluorine pump assembly.

[0060] It can be seen that among the multiple pumps in the fluorine pump assembly, only one pump is in operation in the same time period, thereby effectively ensuring the service life of the fluorine pump assembly; specifically, the fluorine pump assembly is provided with two fluorine pumps, which are a first fluorine pump and a second fluorine pump. When the working time of the first fluorine pump reaches a first predetermined working time, the first fluorine pump is controlled to stop working, and the second fluorine pump is started at the same time. The timing starts when the second fluorine pump starts working. When the working time of the second fluorine pump reaches a second preset working time, the second fluorine pump is controlled to stop working, and the first fluorine pump is started at the same time until the processor temperature of the server is cooled below the preset temperature.

[0061] Optionally, the fluorine pump assembly is provided with three fluorine pumps, which are respectively a first fluorine pump, a second fluorine pump and a third fluorine pump. When the working time of the first fluorine pump reaches a first predetermined working time, the first fluorine pump is controlled to stop working, and the second fluorine pump is started at the same time. The timing starts when the second fluorine pump starts working. When the working time of the second fluorine pump reaches a second preset working time, the second fluorine pump is controlled to stop working, and the third fluorine pump is started at the same time. The timing starts when the third fluorine pump starts working. When the working time of the third fluorine pump reaches a third preset working time, the third fluorine pump is controlled to stop working, and the first fluorine pump is started at the same time, until the processor temperature of the server is cooled down to below the pre-trial temperature.

[0062] In summary, the present application provides an embedded pump-driven two-phase liquid-cooled CDU system and a server, wherein the embedded pump-driven two-phase liquid-cooled CDU system is used to dissipate heat for the server, wherein the server is provided with a plurality of groups of processor chips and cold plates arranged in a one-to-one correspondence, wherein the cold plates are arranged in contact with the processor chips, and wherein the cold plates are used to perform heat exchange on the processor chips, and wherein the embedded pump-driven two-phase liquid-cooled CDU system comprises: a condenser, a liquid storage tank, a control valve and a fluorine pump assembly connected in sequence, and a control assembly electrically connected to the condenser, the control valve and the fluorine pump assembly; wherein the plurality of cold plates are provided in a one-to-one correspondence; wherein the cold plates are provided in contact with the processor chips, and wherein the cold plates are provided in a one-to-one correspondence; wherein the cold plates are provided in contact with the processor chips, and wherein the cold plates are used to perform heat exchange on the processor chips; wherein the embedded pump-driven two-phase liquid-cooled CDU system comprises: a condenser, a liquid storage tank, a control valve and a fluorine pump assembly connected in sequence, and a control assembly electrically connected to the condenser, the control valve and the fluorine pump assembly; wherein the plurality of cold plates are provided in a one-to-one correspondence ...
