Each power device needs to be equipped with a separate heat exchanger for heat dissipation. The inlet and outlet pipes of multiple heat exchangers need to be split or collected by a manifold to the main inlet and outlet pipes. Then, the main inlet and outlet pipes form a refrigeration cycle with an external refrigeration network. When the refrigerant passes through the heat exchanger, it absorbs the heat from the power devices and circulates in the refrigeration network. The heat dissipation of the many power devices in the server rack is achieved by the heat transfer of the refrigerant.
[0003] In the process of developing this application, the applicant discovered that the prior art has at least the following problems:

[0056] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0057] The core of this utility model is to provide an emergency cooling capacity distribution device. Through the built-in heat dissipation module and liquid distribution module, it can not only cope with the failure of the splitter or collector in the cabinet, but also solve the emergency use of the cooling ring network failure, insufficient cooling capacity or the lack of a cooling ring network in the site.
[0058] Please refer to Figures 1-4 and Figures 8-11 As shown, an emergency cooling distribution device is used for heat dissipation of power equipment;
[0059] Emergency cooling distribution equipment includes:
[0060] Heat dissipation module;
[0061] The interface module includes at least one port, which is connected to either the liquid inlet or the liquid outlet of the heat dissipation module via the main valve assembly.
[0062] The manifold module includes at least one set of manifolds. The main interface of the manifold is connected to one of the following via an auxiliary valve group: the liquid inlet of the heat dissipation module, the liquid outlet of the heat dissipation module, or the port of the interface module. The branch pipes of the manifold are used to connect to the liquid inlets and / or outlets of several sets of heat exchangers in the power equipment.
[0063] In practical use, when the manifold inside the cabinet fails, the refrigerant circulation loop of the power module heat exchanger is switched to the manifold module, and the interface module is connected to the cooling ring network. At this time, the manifold module can replace the manifold inside the cabinet to achieve normal heat dissipation of different power modules.
[0064] Meanwhile, when the cooling ring network fails or the cooling capacity is insufficient, the heat dissipation module is activated to cool the refrigerant in place of the cooling ring network, thereby ensuring the normal heat dissipation of the power module. Similarly, for cabinets that do not have a cooling ring network, the heat dissipation module can be used directly to cool the refrigerant in the heat exchanger of the power module, thereby reducing the construction cost of the cabinet heat dissipation system and shortening the construction cycle.
[0065] In some embodiments, the main valve assembly is a directional valve, the main port of the directional valve is connected to the port of the interface module, and the branch ports of the directional valve are connected to the liquid inlet and the liquid outlet of the heat dissipation module, respectively.
[0066] or,
[0067] The main valve assembly includes a first on / off valve and a second on / off valve connected in series between the liquid inlet and the liquid outlet of the heat dissipation module, and the port of the interface module is connected to the pipeline between the first on / off valve and the second on / off valve.
[0068] In some embodiments, the auxiliary valve group is a reversing valve, the main port of the reversing valve is connected to the main interface of the manifold, and the branch ports of the reversing valve are connected to the liquid inlet of the heat dissipation module, the liquid outlet of the heat dissipation module and the port of the interface module, respectively.
[0069] or,
[0070] The main interface of the manifold is connected to the liquid inlet of the heat dissipation module, the liquid outlet of the heat dissipation module, and the port of the interface module through three sets of on / off valves.
[0071] In some embodiments, the interface module includes a first port and a second port;
[0072] The first port of the interface module is connected to the liquid outlet of the heat dissipation module through the first valve group, and the second port of the interface module is connected to the liquid inlet of the heat dissipation module through the second valve group.
[0073] The main interface of the manifold is connected to one of the following via a third valve group: the liquid inlet of the heat dissipation module, the liquid outlet of the heat dissipation module, the first port of the interface module, and the second port of the interface module.
[0074] like Figure 9 , Figure 10 and Figure 11 As shown, the interface module has only one set of ports, and each port is selectively connected to either the liquid inlet or the liquid outlet of the heat dissipation module. When the splitter in the cabinet fails, and the cooling ring network is used as the cooling source,
[0075] The liquid outlet of the cooling ring network, the liquid inlet of the heat dissipation module, the port of the interface module, and the main interface of the manifold are connected in series. The main interface of the manifold in the cabinet is connected to the liquid inlet of the cooling ring network to realize the circulation of refrigerant.
[0076] When the distributor in the cabinet fails and the cooling ring network is selected as the cooling source, the liquid outlet of the heat dissipation module, the port of the interface module, and the main interface of the distributor are connected in series in sequence, and the liquid inlet of the heat dissipation module is connected to the main interface of the distributor in the cabinet to realize the circulation of refrigerant.
[0077] When the manifold in the cabinet fails and the cooling ring network is selected as the cooling source, the main interface of the manifold, the port of the interface module, the liquid outlet of the heat dissipation module, and the liquid inlet of the cooling ring network are connected in series in sequence. The liquid outlet of the cooling ring network is connected to the main interface of the manifold in the cabinet to realize the circulation of refrigerant.
[0078] When the manifold in the cabinet fails and the cooling module is selected as the cooling source, the liquid outlet of the cooling module should be kept connected to the main interface of the manifold in the cabinet. The main interface of the manifold, the port of the interface module, and the liquid inlet of the cooling module should be connected in series to achieve the circulation of refrigerant.
[0079] Both the main valve group and the auxiliary valve group can use directional valves to meet the requirement of selective conduction, or they can be used in combination with multiple on / off valves to meet the requirement of selective conduction.
[0080] In some embodiments, this emergency cooling capacity distribution device includes:
[0081] Cabinet 17, with a walking assembly 1702 installed at its bottom;
[0082] The heat dissipation module is located inside cabinet 17;
[0083] The interface module has a first port connected to the liquid outlet of the heat dissipation module through a first valve group, and a second port connected to the liquid inlet of the heat dissipation module through a second valve group. Both the first and second ports of the interface module extend to the outside of the cabinet 17.
[0084] The manifold module includes at least one set of manifolds. The main interface of the manifold is connected to one of the following through a third valve group: the liquid inlet of the heat dissipation module, the liquid outlet of the heat dissipation module, the liquid inlet of the interface module, and the liquid outlet of the interface module. The branch pipe of the manifold extends to the outside of the cabinet 17 and is used to connect with the liquid inlets and / or outlets of several sets of heat exchangers in the power equipment.
[0085] like Figure 5 and Figure 7 As shown, a walking component 1702 is installed at the bottom of the cabinet 17 to improve the overall mobility of the equipment, allowing it to be repositioned as needed and facilitating emergency use.
[0086] At the same time, the first and second ports of the interface module are both connected to the chuck 1, which is used for the rapid connection of the liquid inlet and outlet of the upper liquid inlet of the cooling ring network, and / or the rapid connection of the main liquid inlet pipe and the main liquid outlet pipe of the cabinet.
[0087] Meanwhile, the branch port of the manifold is set on the side of the cabinet 17 to facilitate the connection of the inlet pipe and / or outlet pipe of the heat exchanger of the power module.
[0088] In some embodiments, the first valve group is a reversing valve, the main port of the reversing valve is connected to the main interface of the manifold, and the branch ports of the reversing valve are connected to the first port of the interface module and the liquid outlet of the heat dissipation module, respectively.
[0089] or,
[0090] The first valve group includes a first on / off valve 2 and a second on / off valve 4 connected in series between the first port of the interface module and the liquid outlet of the heat dissipation module. The main interface of the manifold is connected to the pipeline between the first on / off valve 2 and the second on / off valve 4.
[0091] like Figure 2 As shown, the flow distribution module includes only one set of flow distribution units, which are used as flow distributors. Its main interface is connected to either the liquid outlet of the heat dissipation module or the first port of the interface module through the first valve group. Its application scenario is to replace the flow distributor in the cabinet.
[0092] During use, keep the main interface of the manifold connected to the first port of the interface module, and close the outlet of the heat dissipation module. Connect the inlet pipes of several power module heat exchangers to the branch ports of the manifold one by one. Connect the first port of the interface module to the main outlet pipe of the refrigeration ring network. The low-temperature refrigerant of the refrigeration ring network is diverted by the manifold and enters the heatsinks of different power modules, thereby achieving heat dissipation of different power modules. Subsequently, the high-temperature refrigerant after passing through the heat exchangers of the power modules is collected by the collector in the cabinet and converges to the main outlet pipe of the cabinet. The main outlet pipe of the cabinet is connected to the inlet pipe of the refrigeration ring network, thereby realizing the circulation of refrigerant and achieving continuous heat dissipation of the cabinet.
[0093] or,
[0094] During use, keep the main interface of the manifold connected to the outlet of the heat dissipation module, and close the first port of the interface module. Connect the main outlet pipe of the cabinet to the second port of the interface module, and connect the second port of the interface module to the inlet of the heat dissipation module. At this time, the high-temperature refrigerant after passing through the heat exchanger of the power module is collected by the manifold in the cabinet and converges to the main outlet pipe of the cabinet. Then it enters the heat dissipation module for cooling. After cooling, the low-temperature refrigerant is divided by the manifold and enters the heat dissipation of different power modules, thereby realizing the heat dissipation of different power modules.
[0095] In some embodiments, the second valve group is a reversing valve, the main port of the reversing valve is connected to the main interface of the manifold, and the branch ports of the reversing valve are connected to the second port of the interface module and the liquid inlet of the heat dissipation module, respectively.
[0096] or,
[0097] The second valve group includes a first on / off valve 2 and a second on / off valve 4 connected in series between the second port of the interface module and the liquid inlet of the heat dissipation module. The main interface of the manifold is connected to the pipeline between the first on / off valve 2 and the second on / off valve 4.
[0098] like Figure 3 As shown, the flow distribution module includes only one set of flow distributors, which are used as flow distributors. Its main interface is connected to either the liquid inlet of the heat dissipation module or the second port of the interface module through the second valve group.
[0099] During use, keep the main interface of the manifold connected to the second port of the interface module, and close the liquid inlet of the heat dissipation module. At this time, connect the second port of the interface module to the liquid inlet of the cooling ring network, and connect the branch ports of the manifold to the liquid outlet of the power module heat exchanger one by one. At this time, the low-temperature coolant in the cooling ring network is diverted by the manifold in the cabinet and enters the heat exchanger of the power module to cool the power module. Subsequently, the high-temperature coolant is collected by the manifold and flows back to the liquid inlet of the cooling ring network through the second port of the interface module to realize the circulation of the coolant.
[0100] or,
[0101] During use, keep the main interface of the manifold connected to the liquid inlet of the heat dissipation module, the second port of the interface module closed, the liquid outlet of the heat dissipation module connected to the first interface of the interface module, and the first interface of the interface module connected to the main liquid inlet pipe of the cabinet. At this time, the low-temperature refrigerant enters the cabinet through the first interface of the interface module, and after being diverted by the manifold in the cabinet, it enters the heat exchanger of the power module for heat exchange. The high-temperature refrigerant is collected by the manifold and enters the heat dissipation module for cooling, thereby realizing the circulation of refrigerant.
[0102] It is worth noting that when only one of the splitter or collector in the cabinet is damaged, and the cooling ring network is still being used for heat dissipation, it can be used as a replacement regardless of whether the splitter or collector is located at the liquid inlet or outlet of the cooling module.
[0103] In some embodiments, the first valve group, the second valve group, and the third valve group are all reversing valves. The branch ports of the first valve group are respectively connected to the first port of the interface module and the liquid outlet of the heat dissipation module. The branch ports of the second valve group are respectively connected to the second port of the interface module and the liquid inlet of the heat dissipation module. The main ports of the first valve group and the second valve group are both connected to the branch ports of the third valve group. The main port of the third valve group is connected to the main interface of the manifold.
[0104] like Figure 4 As shown, through the combined use of the first valve group, the second valve group, and the third valve group, the main interface of the manifold can be selectively connected to the liquid inlet of the heat dissipation module, the liquid outlet of the heat dissipation module, the liquid inlet of the interface module, and the liquid outlet of the interface module. Therefore, in use, the manifold can be used as a splitter or a collector according to the requirements, satisfying the replacement use of a single failure of the collector and splitter in the cabinet, and satisfying the replacement use of the heat dissipation module as a cooling source.
[0105] In some embodiments, the flow distribution module includes two flow collectors, one of which is selectively connected to the outlet of the heat dissipation module through the first port of the fourth valve group and the interface module, and the other flow collector is selectively connected to the inlet of the heat dissipation module through the second port of the fifth valve group and the interface module.
[0106] like Figure 1 As shown, the diversity module is equipped with two sets of collectors, which are used separately as collector 3 and distributor 14, respectively, to meet the needs of simultaneous failure of collectors and distributors in the cabinet or single failure.
[0107] It also allows the heat dissipation module to be used as a backup cooling source.
[0108] Taking the simultaneous failure of the collector and distributor in the cabinet as an example, and using the cooling ring network as the cooling source, during use, the inlet and outlet pipes of the power module are connected to the branch ports of distributor 14 and collector 3, respectively. The main interfaces of distributor 14 and collector 3 are connected to the first and second ports of the interface module, respectively. The first and second ports of the interface module are connected to the inlet and outlet of the cooling ring network, respectively, while keeping the inlet and outlet of the heat dissipation module closed. At this time, the low-temperature refrigerant in the cooling ring network is diverted by distributor 14 and enters the heat exchanger of the power module. The high-temperature refrigerant is collected by collector 3 and enters the cooling ring network for cooling, thus realizing the circulation of refrigerant.
[0109] Taking the simultaneous failure of the collector and distributor in the cabinet as an example, and using the heat dissipation module as the cooling source, during use, the inlet and outlet pipes of the power module are connected to the branch ports of the distributor 14 and the collector 3, respectively. The main interfaces of the distributor 14 and the collector 3 are connected to the outlet and inlet of the heat dissipation module, respectively. The first and second ports of the interface module are kept closed. At this time, the low-temperature refrigerant in the heat dissipation module is diverted by the distributor 14 and enters the heat exchanger of the power module. The high-temperature refrigerant is collected by the collector 3 and enters the heat dissipation module for cooling, thus realizing the circulation of refrigerant.
[0110] In some embodiments, the branch ports of the two groups of collectors are arranged in parallel.
[0111] like Figure 7 As shown, the two groups of collectors are arranged in parallel, and the branch ports of the two groups of collectors are set in parallel. The branch ports of the collectors can be set on the outside of the side wall of the cabinet 17, or as shown in the figure. Figure 7 As shown, the branch port is set inside the cabinet 17, and an openable and closable cabinet door is set at the corresponding position of the cabinet 17 to facilitate the insertion of the branch port.
[0112] Meanwhile, the two sets of chucks 1 of the interface module are also set on the outside of the side wall of the cabinet 17, and the chucks 1 and the branch port of the manifold are on the same side of the cabinet 17, so that the pipe interface is set on one side, which facilitates the connection and management of the pipe.
[0113] In some embodiments, the device also includes an electrically operated two-way regulating valve 15, and the heat dissipation module is connected in parallel with the electrically operated two-way regulating valve 15.
[0114] like Figure 1 As shown, an electric two-way regulating valve 15 is connected in parallel at the heat dissipation module. By adjusting the flow rate of the electric two-way regulating valve 15, the problem of excessive pressure difference between the outlet and inlet of the heat dissipation module can be solved. Specifically, when the pressure difference between the outlet and inlet of the heat dissipation module is too large, the electric two-way regulating valve 15 diverts some of the refrigerant at the outlet back to the inlet and re-enters the heat dissipation module for circulation, thereby reducing the outlet pressure and ensuring stable refrigerant pressure throughout the entire refrigeration cycle.
[0115] In some embodiments, the heat dissipation module includes a circulating pump 10 and an air-cooled heat exchanger assembly 11 connected in series, and an axial flow fan 1103 for forced heat dissipation is provided outside the air-cooled heat exchanger assembly 11.
[0116] like Figure 1 As shown, the heat dissipation module adopts a combination of circulating pump 10 and air-cooled heat exchanger assembly 11 to ensure the flow rate of refrigerant in the heat dissipation module, while the cooling effect of refrigerant is guaranteed by the action of axial flow fan 1103.
[0117] In some embodiments, the heat dissipation module includes several sets of sub-heat exchangers 1104 and several sets of axial flow fans 1103;
[0118] All sub-heat exchangers 1104 are connected in series or in parallel, and there is an angle between adjacent groups of sub-heat exchangers 1104. An axial flow fan 1103 is installed on the surface of the cabinet 17 opposite the windward side of the sub-heat exchanger 1104, and a mesh-like cabinet door 1701 is provided on the surface of the cabinet 17 opposite the windward side of the sub-heat exchanger 1104.
[0119] like Figure 5 , Figure 6 , Figure 8 As shown, the air-cooled heat exchanger assembly 11 includes several sets of sub-heat exchangers 1104. Through the reasonable layout of the sub-heat exchangers 1104, the overall air-facing area of the air-cooled heat exchanger assembly 11 is increased, thereby improving the overall heat exchange efficiency of the air-cooled heat exchanger assembly 11. At the same time, the two corresponding sides of the cabinet 17 are respectively provided with a mesh-like cabinet door 1701 and an axial flow fan 1103 to ensure smooth airflow through the cabinet 17 and reduce airflow resistance, which also helps to improve the cooling effect of the heat dissipation module.
[0120] In some embodiments, the heat dissipation module can be achieved by adding a compressor, which, together with the refrigerant in the refrigeration cycle, transfers heat through phase change, thus achieving the same purpose as described above.
[0121] In some embodiments, the heat dissipation module also includes a circulating pump 10 connected in series, with a second pressure sensor 1001 respectively installed at the upstream and downstream ends of the circulating pump 10 for detecting the inlet and outlet pressures of the circulating pump 10.
[0122] like Figure 1 As shown, by adding a circulation pump 10, the refrigerant in the heat dissipation module is provided with the power to flow. At the same time, second pressure sensors 1001 are set upstream and downstream of the circulation pump 10 to detect the inlet and outlet pressures of the circulation pump 10, which are used for power regulation of the circulation pump 10 to ensure that the pressure and flow rate of the refrigerant in the heat dissipation module are constant.
[0123] In some embodiments, a liquid replenishment component 7 is provided at the beginning of the heat dissipation module. The liquid replenishment component 7 includes a liquid replenishment tank 701 and a liquid replenishment pump 702 connected in series. The water inlet of the liquid replenishment tank 701 extends to the outside of the cabinet 17.
[0124] like Figure 1 As shown, in actual use, when switching the heat dissipation module as the cooling source, there is insufficient refrigerant in the pipeline and refrigerant loss due to the failure of the original equipment. Therefore, a refrigerant replenishment component 7 is added. The refrigerant in the refrigerant tank 701 is drawn by the refrigerant replenishment pump 702 to replenish the refrigerant in the heat dissipation module. When setting the refrigerant replenishment component 7, it is preferable to connect and set the refrigerant replenishment component 7 upstream of the circulation pump 10.
[0125] In some embodiments, a drain valve is provided at the beginning of the heat dissipation module and / or the bottom of the sub-heat exchanger 1104, and the drain valve extends to the outside of the cabinet 17.
[0126] And / or,
[0127] The top of the manifold and / or sub-heat exchanger 1104 is provided with an exhaust valve for the discharge of gas inside.
[0128] like Figure 1 As shown, a second manual drain valve 16 is set at the beginning of the heat dissipation module, and a first manual drain valve 1101 is set at the bottom of the sub-heat exchanger 1104 or the bottom of the air-cooled heat exchanger assembly 11. Both can meet the draining requirements of the heat dissipation module to avoid excessive pressure of the refrigerant in the heat dissipation module and ensure the safe operation of the equipment.
[0129] like Figure 1 As shown, a first manual exhaust valve 301 is provided on the top of the distributor 14, an automatic exhaust valve 1401 is provided on the top of the collector 3, and a second manual exhaust valve 1102 is provided on the top of the sub-heat exchanger 1104 or the top of the air-cooled heat exchanger assembly 11. That is, exhaust valves are provided in areas where gas is prone to accumulate, so as to release the gas stored in these locations and ensure the safe and stable operation of the heat dissipation module.
[0130] In some embodiments, at least one of the following components—a degassing tank 9, a filter assembly 12, an expansion tank 8, and a safety valve 13—is connected in series within the heat dissipation module.
[0131] Degassing tank 9 is used for degassing liquids in pipelines;
[0132] The filter assembly 12 is used to filter liquid impurities in the pipeline;
[0133] Expansion tank 8 is used to stabilize the pressure of liquids in pipelines;
[0134] Safety valve 13 is used for the safe pressure relief of the pipeline.
[0135] like Figure 1 As shown, at least one of the following components—a degassing tank 9, a filter assembly 12, an expansion tank 8, and a safety valve 13—is connected in series throughout the entire circuit of the heat dissipation module.
[0136] The degassing tank 9 is preferably connected in series at the beginning of the heat dissipation module to facilitate the degassing of the refrigerant entering the heat dissipation module, thereby improving the cooling effect of the refrigerant.
[0137] The filter assembly 12 is preferably located at the end of the heat dissipation module to filter the refrigerant passing through the heat dissipation module and reduce impurities in the refrigerant entering the cabinet. At the same time, a third pressure sensor 1201 is set at the upstream end of the filter assembly 12 to detect the refrigerant pressure upstream of the filter assembly 12. By comparing the refrigerant pressure upstream of the filter assembly 12 with the refrigerant pressure at the outlet of the heat dissipation module, the degree of blockage of the filter assembly 12 can be determined, and the filter assembly 12 can be cleaned or replaced as appropriate.
[0138] The expansion tank 8 is preferably connected in series at the beginning of the heat dissipation module to facilitate the absorption of turbulence of the refrigerant entering the heat dissipation module, thereby stabilizing the pressure of the liquid in the entire system pipeline and ensuring the stability of the liquid circulation in the heat dissipation module.
[0139] Safety valve 13 is preferably connected in series at the end of the heat dissipation module to ensure that the pressure of the refrigerant after being pressurized by the circulation pump 10 does not exceed the operating pressure of the cabinet, thus ensuring the safe use of the equipment.
[0140] In some embodiments, the drain pipe of safety valve 13 is connected to a liquid collection mechanism.
[0141] By installing a drain pipe at the outlet of the safety valve 13 and extending the drain pipe to the outside of the cabinet 17, it is convenient to discharge the refrigerant discharged by the safety valve 13 to the outside of the cabinet 17, thus avoiding its accumulation inside the cabinet 17.
[0142] Alternatively, the replenishment tank 701 can be used as a liquid collection mechanism, with the drain pipe directly connected to the replenishment tank 701, to collect the refrigerant discharged by the safety valve 13 in the replenishment tank 701 for reuse.
[0143] In some embodiments, temperature sensors 6 are provided at both the beginning and end of the heat dissipation module to detect the liquid temperature at the inlet and outlet of the heat dissipation module, respectively.
[0144] And / or,
[0145] A first pressure sensor 5 is installed at both the beginning and end of the heat dissipation module to detect the liquid pressure at the inlet and outlet of the heat dissipation module.
[0146] like Figure 1 As shown, by setting temperature sensors 6 at the beginning and end of the heat dissipation module respectively, the inlet and outlet temperatures of the heat dissipation module are detected to obtain the temperature difference, and then the power of the heat dissipation module is adjusted, thereby realizing the heat dissipation effect control of the power module in the cabinet.
[0147] Similarly, by setting the first pressure sensor 5 at the beginning and end of the heat dissipation module respectively, the inlet and outlet pressures of the heat dissipation module are detected to obtain the pressure difference, which facilitates the regulation of the flow rate of the electric two-way regulating valve 15 to ensure the stability of the refrigerant pressure in the entire system.
[0148] In some embodiments, a display and control module 1704 and a power interface 1703 are provided on the outside of the side wall of the cabinet 17. The power interface 1703 is used for quick plug-in power supply of the device, and the display and control module 1704 is used to display the parameters of the device and control the device.
[0149] A power interface 1703 is provided on one side of the cabinet 17 to facilitate external power supply to the equipment. At the same time, a display and control module 1704 is provided on the side wall of the cabinet 17 to facilitate the display of various parameters of the equipment and the control of the equipment, thereby improving the convenience of using the equipment.
[0150] The control method for this emergency cooling capacity distribution equipment, such as Figure 12 As shown, the steps include:
[0151] The host computer is controlled to obtain the maximum difference Tx1 between the actual temperatures T of several power modules;
[0152] Determine whether the maximum difference Tx1 is greater than the preset value T1;
[0153] If so, the control interface module and the diversity stream module are connected;
[0154] If not, the host computer obtains the average value Tp of several sets of actual power module temperatures T and the difference Tx2 between the preset control temperature To;
[0155] Determine whether the difference Tx2 is greater than the preset value T2;
[0156] If so, control the heat dissipation module and the diversity current module to conduct, and control the heat dissipation module to start, until the average value Tp of the actual temperature T is not greater than the preset control temperature To;
[0157] If not, return to the step of controlling the host computer to obtain the maximum difference Tx1.
[0158] During use, the host computer is used to detect the temperature of different power modules in the cabinet to obtain the temperature difference between the different power modules. When the temperature difference is large, it indicates that one or all of the branch ports of the splitter in the cabinet have failed, which affects the heat dissipation of the corresponding power module and leads to abnormal temperature. At this time, the splitter module is switched to solve the heat dissipation abnormality caused by the splitter failure in the cabinet.
[0159] Meanwhile, when the overall temperature of the power module exceeds the preset control temperature, it indicates a malfunction in the cooling ring network or insufficient cooling capacity. In this case, the heat dissipation module is switched to a cooling source or a supplementary cooling source is used to divert all or part of the high-temperature refrigerant to the heat dissipation module to resolve the abnormal heat dissipation caused by the malfunction in the cooling ring network or insufficient cooling capacity.
[0160] In some embodiments, the heat dissipation module further includes an electrically operated two-way regulating valve 15, and the heat dissipation module and the electrically operated two-way regulating valve 15 are connected in parallel.
[0161] If so, the control module connects to the heat dissipation module and the diversity current module, and the control module starts up, until the average value Tp of the actual temperature T is not greater than the preset control temperature To, including the following steps:
[0162] The host computer is controlled to obtain the inlet pressure P1 and outlet pressure P2 of the heat dissipation module.
[0163] Determine whether the difference Px between pressure P1 and pressure P2 is greater than the preset value P, where Px = P2 - P1;
[0164] If so, control the electric two-way regulating valve 15 to increase the flow rate until the difference Px is not greater than the preset value P;
[0165] If not, control the electric two-way regulating valve 15 to reduce the flow rate until the difference Px equals the preset value P.
[0166] When the heat dissipation module is used as a cooling source, the pressure difference between the inlet and outlet of the heat dissipation module is obtained by detecting the pressure at the inlet and outlet. When the pressure difference exceeds the preset value, it indicates that the pressure at the outlet of the heat dissipation module is too high. Therefore, the flow rate is adjusted by the electric two-way regulating valve 15 to divert part of the refrigerant, so that the refrigerant at the outlet end flows back to the heat dissipation module for recirculation through the electric two-way regulating valve 15, thereby ensuring the pressure stability within the entire refrigeration cycle.
[0167] In some embodiments, a circulation pump 10 is connected in series within the heat dissipation module;
[0168] Among them, controlling the electric two-way regulating valve 15 to increase the flow rate until the difference Px is not greater than the preset value P, before the following includes:
[0169] Control the circulation pump 10 to reduce power, and after a preset time, determine whether Px is greater than P;
[0170] If so, control the electric two-way regulating valve 15 to increase the flow rate until the difference Px is not greater than the preset value P.
[0171] Before adjusting the flow rate of the electric two-way regulating valve 15, the power of the circulating pump 10 is reduced to decrease the pressure difference between the outlet and the inlet, thus saving energy. Only when the pressure difference between the outlet and the inlet continues to exceed the preset value after reducing the power of the circulating pump 10, pressure is released by adjusting the flow rate of the electric two-way regulating valve 15.
[0172] In some embodiments, a circulation pump 10 is connected in series within the heat dissipation module;
[0173] The process includes controlling the electric two-way regulating valve 15 to reduce the flow rate until the difference Px equals the preset value P, followed by:
[0174] After a preset time, determine whether Px equals P;
[0175] If not, control the circulation pump 10 to increase its power.
[0176] When the pressure difference between the liquid outlet and the liquid inlet is less than the preset value, the flow rate of the electric two-way regulating valve 15 is reduced, that is, the amount of refrigerant flowing back is reduced, in order to increase the pressure difference between the liquid outlet and the liquid inlet. If the pressure difference between the two continues to be less than the preset value, the pressure difference between the two is increased by increasing the power of the circulating pump 10, that is, by increasing the energy consumption of the equipment, the pressure at the liquid outlet of the heat dissipation module is guaranteed.
