[0019] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0021] Figure 1The system structure schematic diagram 100 of the dry cooler system with antifreeze function applicable to the present disclosure is shown. The dry cooler system 100 with antifreeze function includes a dry cooler 101, a self-circulation pipeline 102, a controller 103 and a preset adjustment device 104. Among them, the dry cooler 101 is connected with the self-circulation pipeline 102, and the preset adjustment device 104 is arranged on the self-circulation pipeline 102; the dry cooler 101 is connected with the main circulation pipeline 105 in the liquid cooling system; the main circulation pipeline 105 is provided with a bypass pipeline 106 of the liquid cooling system relative to the dry cooler; the controller 103 is used to determine the target state quantity of the brine flowing through the dry cooler 101 during the main circulation process when the dry cooler 101 participates in the main circulation process through the main circulation pipeline 105; according to the target state quantity, determine whether to start the antifreeze self-circulation mode based on the preset adjustment device 104 through the self-circulation pipeline 102 to adjust the target state quantity of the brine in the dry cooler 101. In the antifreeze self-circulation mode, the coolant self-circulates in the dry cooler 101 and the self-circulation pipeline 102 .

[0022] A dry cooler, also known as a dry cooler, does not consume any water during its working process. It cools the liquid in the pipe by letting the liquid flow through the internal pipe and letting natural wind flow outside the pipe, thereby reducing the temperature of the refrigerant in the pipe and achieving the cooling purpose.

[0023] The liquid cooling system is a system that uses liquid to exchange heat for heat. Taking a liquid-cooled data center as an example, liquid is injected into the data center to cool the servers in the data center through heat exchange.

[0024] In this embodiment, the main cycle process represents the cycle process in which the coolant in the liquid cooling system absorbs heat at a heat source (such as a data center) and releases heat at a cold source (such as a dry cooler). Figure 1 The circulation process of the coolant in the dry cooler 101, CDU (Coolant distribution unit) 107, and liquid cooling data center 108 can be regarded as the main circulation process. It should be noted that Figure 1 The liquid cooling system shown in FIG. 1 is merely an exemplary description and is not intended to limit the liquid cooling system.

[0025] The self-circulation process indicates that the dry cooler does not participate in the main circulation process of the liquid cooling system, that is, it does not exchange heat with the liquid cooling system, and the refrigerant in the dry cooler 101 only circulates in the internal pipeline of the dry cooler 101 and the self-circulation pipeline 102.

[0026] Specifically, the controller 103 can control the first electric control valve 109 and the second electric control valve 110 to be closed, and control the fourth electric control valve 112 to be opened, so that the dry cooler is in the self-circulation mode. The controller 103 can also control the first electric control valve 109 and the second electric control valve 110 to be opened, and control the fourth electric control valve 112 to be closed, so that the dry cooler exits the self-circulation mode.

[0027] The target state of the brine may be, for example, flow rate, temperature, flow velocity, etc. As an example, the execution subject may determine the target state of the brine flowing through the dry cooler during the main circulation process based on the temperature sensor 113 and the flow velocity sensor 114 on the main circulation pipeline.

[0028] After determining the target state quantity, the controller determines whether to open the self-circulation pipeline according to the target state quantity, so that the dry cooler performs the self-circulation mode. As an example, when the temperature in the target state quantity is lower than the preset temperature threshold, or the flow rate is lower than the preset flow rate threshold, the self-circulation mode is turned on; otherwise, the self-circulation mode is not turned on, and the liquid cooling system still performs the main circulation process based on the dry cooler.

[0029] The preset adjustment device 104 can adjust the target state of the brine in the main cycle to prevent the brine in the dry cooler from freezing. As an example, the preset adjustment device 104 can heat the brine in the self-cycle or increase the flow rate of the brine in the self-cycle.

[0030] In the present embodiment, a dry cooler system with an antifreeze function is provided, and whether to perform the antifreeze self-circulation process of the dry cooler is controlled according to the target state quantity of the refrigerant flowing through the dry cooler in the main cycle corresponding to the liquid cooling system. During the antifreeze self-circulation process, the target state quantity of the refrigerant can be adjusted to achieve antifreeze of the refrigerant in the dry cooler, thereby improving the antifreeze effect of the dry cooler. Moreover, based on the active adjustment of the target state quantity of the refrigerant, the dry cooler is no longer limited to refrigerants with low freezing points such as ethylene glycol, thereby improving the applicability of the dry cooler to refrigerants. In particular, when water is used as the refrigerant, the energy loss caused by the high viscosity and low specific heat of ethylene glycol is reduced; compared with the corrosiveness and mild toxicity of ethylene glycol, water as a refrigerant improves safety.

[0031] In some optional implementations of this embodiment, the target state quantity includes temperature and flow rate, and a bypass line 106 of the liquid cooling system relative to the dry cooler is provided on the main circulation pipeline. The controller 103 is further used to: in response to determining that the temperature of the secondary coolant flowing through the dry cooler during the main circulation process is lower than the first temperature threshold, and the flow rate is lower than the preset antifreeze minimum flow rate, start the antifreeze self-circulation mode through the self-circulation pipeline 102 and start the bypass mode through the bypass pipeline 106. The preset antifreeze minimum flow rate represents the minimum flow rate to prevent the secondary coolant from freezing, and in the bypass mode, the dry cooler is isolated from the main circulation process.

[0032] In this implementation, the antifreeze self-circulation model of the dry cooler 101 is synchronized with the bypass mode of the liquid cooling system. When the dry cooler 101 performs the above self-circulation process and is in the antifreeze self-circulation mode, the liquid cooling system enters the bypass mode based on the bypass line 106. In the bypass mode, the refrigerant in the liquid cooling system flows back through the bypass line and no longer passes through the dry cooler for heat dissipation. That is, in the bypass mode, the dry cooler is isolated from the main circulation process.

[0033] Specifically, the controller 103 can control the first electric control valve 109 and the second electric control valve 110 to be closed, and control the third electric control valve 111 and the fourth electric control valve 112 to be opened, so that the liquid cooling system is in bypass mode and the dry cooler is in self-circulation mode. The controller 103 can also control the first electric control valve 109 and the second electric control valve 110 to be opened, and control the third electric control valve 111 and the fourth electric control valve 112 to be closed, so that the liquid cooling system exits the bypass mode and the dry cooler exits the self-circulation mode. At this time, the liquid cooling system performs the main circulation, and the dry cooler participates in the main circulation of the liquid cooling system.

[0034] The first temperature threshold and the preset antifreeze minimum flow rate can be specifically set according to actual conditions. For example, the first temperature threshold is 10°C.

[0035] The freezing of the refrigerant is greatly affected by the temperature of the outer surface of the pipe wall. When the flow rate in the pipe is greater than laminar flow, the freezing of the refrigerant can be prevented. Laminar flow is a flow state of fluid, which flows in layers. In laminar flow, the cross-sectional distribution of the flow velocity is uneven, and the water flow near the pipe wall is almost static. According to Re=ρvd / η<2300, the preset minimum antifreeze flow rate can be determined. Among them, v, ρ, η are the flow velocity, density and viscosity coefficient of the refrigerant respectively, and r is a characteristic line. For the refrigerant in the pipeline, r is the radius of the pipeline.

[0036] Taking water as the coolant as an example, when the diameter of the pipe where the coolant is located is 15mm, the flow rate is less than 0.15m / s, which is laminar flow. Therefore, the preset antifreeze minimum flow rate can be set to 0.15m / s.

[0037] In this implementation, when the temperature of the coolant flowing through the dry cooler during the main cycle is not lower than the first temperature threshold, or the flow rate is not lower than the preset antifreeze minimum flow rate, the bypass mode is not entered.

[0038] In this implementation, a specific method is provided for determining whether to open the bypass line according to the target state quantity, and the accuracy of the mode switching is improved based on the dual determination of temperature and flow rate.

[0039] In some optional implementations of this embodiment, the preset adjustment device 104 includes a brine flow rate adjustment device. The brine flow rate adjustment device may be any device capable of adjusting the flow rate of the brine. As an example, the brine flow rate adjustment device may be Figure 1 The circulating water pump 1041 shown in the figure can determine the flow rate of the coolant in the self-circulation according to the flow rate sensor 116 arranged on the self-circulation pipeline.

[0040] In this implementation, the controller 103 is further used to: determine the temperature of the coolant in the antifreeze self-circulation mode; in response to determining that the temperature of the coolant in the antifreeze self-circulation mode is not lower than the second temperature threshold, adjust the flow rate of the coolant in the antifreeze self-circulation mode to a preset antifreeze minimum flow rate through the coolant flow rate adjustment device. The second temperature threshold is lower than the first temperature threshold.

[0041] The second temperature threshold can be set according to actual conditions. As an example, the second temperature threshold is 4°C.

[0042] Continue to refer to Figure 1 , the controller 103 determines the temperature of the coolant in the antifreeze self-circulation mode through the temperature sensor 115 on the self-circulation pipeline 102. When the temperature of the coolant is not lower than the second temperature threshold, that is, between the first temperature threshold and the second temperature threshold, the flow rate of the coolant in the antifreeze self-circulation mode is adjusted to the preset antifreeze minimum flow rate through the circulating water pump.

[0043] In this implementation, the temperature of the refrigerant in the antifreeze self-circulation mode is not lower than the second temperature threshold. By adjusting the flow rate of the refrigerant to the preset antifreeze minimum flow rate, the energy loss of the dry cooler due to antifreeze is reduced while ensuring the antifreeze effect.

[0044] In some optional implementations of this embodiment, the preset adjustment device includes a coolant temperature adjustment device. The coolant temperature adjustment device may be any device capable of adjusting the temperature of the coolant. As an example, the coolant temperature adjustment device may be Figure 1 The heating buffer tank 1042 is shown in FIG.

[0045] In this implementation, the controller 103 is also used to: in response to determining that the temperature of the coolant in the antifreeze self-circulation mode is lower than the second temperature threshold, adjust the temperature of the coolant in the antifreeze self-circulation mode through the coolant temperature adjustment device.

[0046] When the temperature of the coolant in the antifreeze self-circulation mode is lower than the second temperature threshold, the antifreeze effect may not be guaranteed by adjusting the flow rate of the coolant. At this time, the temperature of the coolant in the antifreeze self-circulation mode can be adjusted by the coolant temperature adjustment device.

[0047] In this implementation, in an extremely low temperature environment, the temperature of the refrigerant in the antifreeze self-circulation mode is adjusted by the refrigerant temperature adjustment device, thereby ensuring the antifreeze effect of the dry cooler in the extremely low temperature environment.

[0048] In this implementation, while the refrigerant temperature adjustment device adjusts the temperature of the refrigerant in the antifreeze self-circulation mode, the refrigerant flow rate adjustment device can be used to adjust the flow rate of the refrigerant. The antifreeze effect of the refrigerant is ensured by combining these two methods.

[0049] As an example, a controller or an electronic device communicatively connected to the controller is provided with a correspondence table for characterizing the adjustment amount of the refrigerant temperature adjustment device, the adjustment amount of the refrigerant flow rate adjustment device and the actually collected temperature and flow rate. The adjustment amount of the refrigerant temperature adjustment device, the adjustment amount of the refrigerant flow rate adjustment device are determined according to the acquired temperature and flow rate according to the correspondence table.

[0050] In some optional implementations of this embodiment, the controller is further used to: control the heating amount of the refrigerant temperature adjustment device according to the temperature of the refrigerant in the antifreeze self-circulation mode.

[0051] As an example, there is a negative correlation between the temperature of the coolant and the heating amount of the coolant temperature adjustment device. Specifically, the heating amount of the coolant temperature adjustment device can be controlled according to the temperature of the coolant in the antifreeze self-circulation mode through a neural network model. The neural network model characterizes the corresponding relationship between the temperature of the coolant in the antifreeze self-circulation mode and the heating amount of the coolant temperature adjustment device.

[0052] In this implementation, the controller can control the heating amount of the refrigerant temperature adjustment device in real time according to the temperature of the refrigerant in the antifreeze self-circulation mode, thereby improving the heating effect on the refrigerant and further ensuring the antifreeze effect of the refrigerant.

[0053] In some optional implementations of this embodiment, the controller is further configured to: in response to determining that the temperature of the coolant in the liquid cooling system in the bypass mode is not lower than a third temperature threshold, close the bypass mode and the antifreeze self-circulation mode, so that the dry cooler participates in the main circulation process of the liquid cooling system. The third temperature threshold is higher than the first temperature threshold.

[0054] The third temperature threshold can be specifically set according to actual conditions and is not limited here.

[0055] Continue to refer to Figure 1 In response to determining that the temperature of the coolant in the liquid cooling system in the bypass mode is not lower than the third temperature threshold, the controller 103 controls the first electric control valve 109 and the second electric control valve 110 to open, and controls the third electric control valve 111 and the fourth electric control valve 112 to close, so that the liquid cooling system exits the bypass mode and the dry cooler exits the self-circulation mode. At this time, the liquid cooling system performs the main circulation, and the dry cooler participates in the main circulation of the liquid cooling system.

[0056] In this implementation, when the temperature of the coolant in the liquid cooling system meets the preset conditions, the main circulation process of the liquid cooling system is restored, thereby improving the operational feasibility of the dry cooler under different conditions.

[0057] Figure 2 An exemplary architecture 200 is shown in which the antifreeze method and apparatus for a dry cooler of the present disclosure may be applied.

[0058] like Figure 1 As shown, the system architecture 200 may include controlled devices 201, 202, 203, a network 204, and a control device 205. The controlled devices 201, 202, 203 are connected to form a topological network, and the network 204 is used to provide a medium for communication links between the controlled devices 201, 202, 203 and the control device 205. The network 204 may include various connection types, such as wired, wireless communication links or optical fiber cables, etc.

[0059] The controlled devices 201, 202, 203 can be hardware devices or software that support network connection for data interaction and data processing. When the controlled devices 201, 202, 203 are hardware, they can be various electronic devices that support network connection, information acquisition, execution and other functions, including but not limited to the electric control valve, heating buffer tank, circulating water pump, target state quantity acquisition device, etc. in the above-mentioned dry cooler system with antifreeze function. When the controlled devices 201, 202, 203 are software, they can be installed in the electronic devices listed above. It can be implemented as multiple software or software modules for providing distributed services, for example, or it can be implemented as a single software or software module. No specific limitation is made here.

[0060] The control device 205 can be a control device that provides various services, for example, a background processing server that issues instructions to the electric control valve, heating buffer tank, and circulating water pump in the above-mentioned dry cooler system with antifreeze function to control the operation of the dry cooler system with antifreeze function. As an example, server 205 can be a cloud server.

[0061] It should be noted that the control device can be hardware or software. When the control device is hardware, it can be implemented as a distributed server cluster consisting of multiple servers, or it can be implemented as a single server. When the server is software, it can be implemented as multiple software or software modules (for example, software or software modules used to provide distributed services), or it can be implemented as a single software or software module. No specific limitation is made here.

[0062] It should also be noted that the antifreeze method for a dry cooler provided in the embodiments of the present disclosure may be executed by a control device. Accordingly, all parts (eg, units) of the antifreeze device for a dry cooler may be disposed in the control device.

[0063] It should be understood that Figure 1 The number of control devices, networks, and controlled devices in the system is only illustrative. Any number of control devices, networks, and controlled devices may be provided as required. When the electronic device on which the antifreeze method applied to the dry cooler is running does not need to perform data transmission with other electronic devices, the system architecture may only include the electronic device (e.g., control device) on which the antifreeze method applied to the dry cooler is running.

[0064] Please refer to Figure 3 , Figure 3 A flowchart of an antifreeze method applied to a dry cooler provided in an embodiment of the present disclosure, wherein process 300 includes the following steps:

[0065] Step 301, during the main circulation process in which the dry cooler participates in the liquid cooling system, a target state quantity of the coolant flowing through the dry cooler during the main circulation process is determined.

[0066] In this embodiment, the execution body of the antifreeze method applied to the dry cooler (for example, Figure 1 The control device in the dry cooler can determine the target state quantity of the coolant flowing through the dry cooler during the main circulation process when the dry cooler participates in the main circulation process of the liquid cooling system.

[0067] A dry cooler, also known as a dry cooler, does not consume any water during its working process. It cools the liquid in the pipe by letting the liquid flow through the internal pipe and letting natural wind flow outside the pipe, thereby reducing the temperature of the refrigerant in the pipe and achieving the cooling purpose.

[0068] The liquid cooling system is a system that uses liquid to exchange heat for heat. Taking a liquid-cooled data center as an example, liquid is injected into the data center to cool the servers in the data center through heat exchange.

[0069] In this embodiment, the main cycle process represents the cycle process in which the coolant in the liquid cooling system absorbs heat at a heat source (such as a data center) and releases heat at a cold source (such as a dry cooler). Figure 1 The circulation process of the coolant in the dry cooler 101, CDU (Coolant distribution unit) 107, and liquid cooling data center 108 can be regarded as the main circulation process. It should be noted that Figure 1 The liquid cooling system shown in FIG. 1 is merely an exemplary description and is not intended to limit the liquid cooling system.

[0070] The target state of the brine may be, for example, flow rate, temperature, flow velocity, etc. As an example, the execution subject may determine the target state of the brine flowing through the dry cooler during the main circulation process based on a temperature sensor and a flow velocity sensor on the main circulation pipeline.

[0071] Step 302 , according to the target state quantity, it is determined whether to start the antifreeze self-circulation mode for adjusting the target state quantity of the refrigerant in the dry cooler based on the preset adjustment device.

[0072] In this embodiment, the execution subject can determine whether to start the antifreeze self-circulation mode based on the target state quantity of the brine in the dry cooler based on the preset adjustment device according to the target state quantity. In the antifreeze self-circulation mode, the brine is self-circulated in the dry cooler and the self-circulation pipeline, and the preset adjustment device is provided on the self-circulation pipeline.

[0073] The self-circulation process indicates that the dry cooler does not participate in the main circulation process of the liquid cooling system, that is, it does not exchange heat with the liquid cooling system, and the refrigerant in the dry cooler 101 only circulates in the internal pipeline of the dry cooler 101 and the self-circulation pipeline 102.

[0074] Continue to refer Figure 1 , the controller 103 can control the first electric control valve 109 and the second electric control valve 110 to close, and control the fourth electric control valve 112 to open, so that the dry cooler is in the self-circulation mode. The controller 103 can also control the first electric control valve 109 and the second electric control valve 110 to open, and control the fourth electric control valve 112 to close, so that the dry cooler exits the self-circulation mode.

[0075] The preset adjustment device can adjust the target state of the brine in the main cycle to prevent the brine in the dry cooler from freezing. As an example, the preset adjustment device can heat the brine in the self-cycle or increase the flow rate of the brine in the self-cycle.

[0076] In the present embodiment, a dry cooler method with an antifreeze function is provided, and whether to perform the antifreeze self-circulation process of the dry cooler is controlled according to the target state quantity of the refrigerant flowing through the dry cooler in the main cycle corresponding to the liquid cooling system. During the antifreeze self-circulation process, the target state quantity of the refrigerant can be adjusted to achieve antifreeze of the refrigerant in the dry cooler, thereby improving the antifreeze effect of the dry cooler. Moreover, based on the active adjustment of the target state quantity of the refrigerant, the dry cooler is no longer limited to refrigerants with low freezing points such as ethylene glycol, thereby improving the applicability of the dry cooler to refrigerants. In particular, when water is used as the refrigerant, the energy loss caused by the high viscosity and low specific heat of ethylene glycol is reduced; compared with the corrosiveness and mild toxicity of ethylene glycol, water as a refrigerant improves safety.

[0077] In some optional implementations of this embodiment, the target state quantity includes temperature and flow rate. The execution subject may perform step 302 as follows: in response to determining that the temperature of the coolant flowing through the dry cooler during the main circulation process is lower than the first temperature threshold, and the flow rate is lower than the preset antifreeze minimum flow rate, the antifreeze self-circulation mode and the bypass mode of the liquid cooling system relative to the dry cooler are turned on. The preset antifreeze minimum flow rate represents the minimum flow rate to prevent the coolant from freezing, and in the bypass mode, the dry cooler is isolated from the main circulation process.

[0078] Continue to refer Figure 1 , the controller 103 can control the first electric control valve 109 and the second electric control valve 110 to close, and control the third electric control valve 111 and the fourth electric control valve 112 to open, so that the liquid cooling system is in bypass mode, and the dry cooler is in self-circulation mode. The controller 103 can also control the first electric control valve 109 and the second electric control valve 110 to open, and control the third electric control valve 111 and the fourth electric control valve 112 to close, so that the liquid cooling system exits the bypass mode, and the dry cooler exits the self-circulation mode. At this time, the liquid cooling system performs the main circulation, and the dry cooler participates in the main circulation of the liquid cooling system.

[0079] The first temperature threshold and the preset antifreeze minimum flow rate can be specifically set according to actual conditions. For example, the first temperature threshold is 10°C.

[0080] The freezing of the refrigerant is greatly affected by the temperature of the outer surface of the pipe wall. When the flow rate in the pipe is greater than laminar flow, the refrigerant can be prevented from freezing. Laminar flow is a flow state of fluid, which flows in layers. In laminar flow, the flow velocity cross-section is unevenly distributed, and the water flow near the pipe wall is almost static. According to Re=ρvd / η<2300, the preset minimum antifreeze flow rate can be determined. Among them, v, ρ, η are the flow velocity, density and viscosity coefficient of the refrigerant respectively, and r is a characteristic line. For the refrigerant in the pipeline, r is the radius of the pipeline.

[0081] Taking water as the coolant as an example, when the diameter of the pipe where the coolant is located is 15mm, the flow rate is less than 0.15m / s, which is laminar flow. Therefore, the preset antifreeze minimum flow rate can be set to 0.15m / s.

[0082] In this implementation, when the temperature of the coolant flowing through the dry cooler during the main cycle is not lower than the first temperature threshold, or the flow rate is not lower than the preset antifreeze minimum flow rate, the bypass mode is not entered.

[0083] In this implementation, a method for determining whether to open the bypass line according to the target state quantity is provided, and the accuracy of mode switching is improved based on the dual determination of temperature and flow rate.

[0084] In some optional implementations of this embodiment, the preset adjustment device includes a coolant flow rate adjustment device. The coolant flow rate adjustment device may be any device capable of adjusting the flow rate of the coolant. As an example, the coolant flow rate adjustment device may be Figure 1 The circulating water pump 1041 shown in FIG.

[0085] At this time, the execution subject can start the antifreeze self-circulation mode for adjusting the target state quantity of the brine in the dry cooler based on the preset adjustment device by performing the following operations: first, determine the temperature of the brine in the antifreeze self-circulation mode; then, in response to determining that the temperature of the brine in the antifreeze self-circulation mode is not lower than the second temperature threshold, adjust the flow rate of the brine in the antifreeze self-circulation mode to the preset antifreeze minimum flow rate through the brine flow rate adjustment device. The second temperature threshold is lower than the first temperature threshold.

[0086] The second temperature threshold can be set according to actual conditions. As an example, the second temperature threshold is 4°C.

[0087] Continue to refer to Figure 1 The execution subject determines the temperature of the coolant in the antifreeze self-circulation mode through a temperature sensor on the self-circulation pipeline. When the temperature of the coolant is not lower than the second temperature threshold, that is, between the first temperature threshold and the second temperature threshold, the flow rate of the coolant in the antifreeze self-circulation mode is adjusted to a preset antifreeze minimum flow rate through the circulating water pump.

[0088] In this implementation, the temperature of the refrigerant in the antifreeze self-circulation mode is not lower than the second temperature threshold. By adjusting the flow rate of the refrigerant to the preset antifreeze minimum flow rate, the energy loss of the dry cooler due to antifreeze is reduced while ensuring the antifreeze effect.

[0089] In some optional implementations of this embodiment, the preset adjustment device includes a coolant temperature adjustment device. The coolant temperature adjustment device may be any device capable of adjusting the temperature of the coolant. As an example, the coolant temperature adjustment device may be Figure 1 The heating buffer tank 1042 is shown in FIG.

[0090] At this time, the above-mentioned execution entity can start the antifreeze self-circulation mode based on adjusting the target state quantity of the refrigerant in the dry cooler based on a preset adjustment device by performing the following operations: in response to determining that the temperature of the refrigerant in the antifreeze self-circulation mode is lower than the second temperature threshold, the temperature of the refrigerant in the antifreeze self-circulation mode is adjusted by the refrigerant temperature adjustment device.

[0091] When the temperature of the coolant in the antifreeze self-circulation mode is lower than the second temperature threshold, the antifreeze effect may not be guaranteed by adjusting the flow rate of the coolant. At this time, the temperature of the coolant in the antifreeze self-circulation mode can be adjusted by the coolant temperature adjustment device.

[0092] In this implementation, in an extremely low temperature environment, the temperature of the refrigerant in the antifreeze self-circulation mode is adjusted by the refrigerant temperature adjustment device, thereby ensuring the antifreeze effect of the dry cooler in the extremely low temperature environment.

[0093] In this implementation, while the refrigerant temperature adjustment device adjusts the temperature of the refrigerant in the antifreeze self-circulation mode, the refrigerant flow rate adjustment device can be used to adjust the flow rate of the refrigerant. The antifreeze effect of the refrigerant is ensured by combining these two methods.

[0094] As an example, a controller or an electronic device communicatively connected to the controller is provided with a correspondence table for characterizing the adjustment amount of the refrigerant temperature adjustment device, the adjustment amount of the refrigerant flow rate adjustment device and the actually collected temperature and flow rate. The adjustment amount of the refrigerant temperature adjustment device, the adjustment amount of the refrigerant flow rate adjustment device are determined according to the acquired temperature and flow rate according to the correspondence table.

[0095] In some optional implementations of this embodiment, the above-mentioned execution entity can adjust the temperature of the refrigerant in the antifreeze self-circulation mode through the refrigerant temperature adjustment device by performing the following operations: controlling the heating amount of the refrigerant temperature adjustment device according to the temperature of the refrigerant in the antifreeze self-circulation mode.

[0096] As an example, there is a negative correlation between the temperature of the coolant and the heating amount of the coolant temperature adjustment device. Specifically, the heating amount of the coolant temperature adjustment device can be controlled according to the temperature of the coolant in the antifreeze self-circulation mode through a neural network model. The neural network model characterizes the corresponding relationship between the temperature of the coolant in the antifreeze self-circulation mode and the heating amount of the coolant temperature adjustment device.

[0097] In this implementation, the controller can control the heating amount of the refrigerant temperature adjustment device in real time according to the temperature of the refrigerant in the antifreeze self-circulation mode, thereby improving the heating effect on the refrigerant and further ensuring the antifreeze effect of the refrigerant.

[0098] In some optional implementations of this embodiment, the above-mentioned execution entity may also perform the following operations: in response to determining that the temperature of the refrigerant in the liquid cooling system in the bypass mode is not lower than a third temperature threshold, turning off the bypass mode and the antifreeze self-circulation mode, so that the dry cooler participates in the main circulation process of the liquid cooling system, wherein the third temperature threshold is higher than the first temperature threshold.

[0099] The third temperature threshold can be specifically set according to actual conditions and is not limited here.

[0100] Continue to refer to Figure 1 In response to determining that the temperature of the coolant in the liquid cooling system in the bypass mode is not lower than the third temperature threshold, the controller 103 controls the first electric control valve 109 and the second electric control valve 110 to open, and controls the third electric control valve 111 and the fourth electric control valve 112 to close, so that the liquid cooling system exits the bypass mode and the dry cooler exits the self-circulation mode. At this time, the liquid cooling system performs the main circulation, and the dry cooler participates in the main circulation of the liquid cooling system.

[0101] In this implementation, when the temperature of the coolant in the liquid cooling system meets the preset conditions, the main circulation process of the liquid cooling system is restored, thereby improving the operational feasibility of the dry cooler under different conditions.

[0102] Continue to refer Figure 4 , shows a schematic process 400 of another embodiment of an antifreeze method applied to a dry cooler according to the present disclosure, comprising the following steps:

[0103] Step 401, during the main circulation process in which the dry cooler participates in the liquid cooling system, a target state quantity of the coolant flowing through the dry cooler during the main circulation process is determined.

[0104] Among them, the target state quantities include temperature and flow rate.

[0105] Step 402 , in response to determining that the temperature of the coolant flowing through the dry cooler during the main cycle is lower than a first temperature threshold, and the flow rate is lower than a preset antifreeze minimum flow rate, the bypass mode is turned on.

[0106] The preset antifreeze minimum flow rate represents the minimum flow rate for preventing the coolant from freezing.

[0107] Step 403, in response to determining to start the bypass mode, start the self-circulation antifreeze mode of the dry cooler, and determine the temperature of the coolant in the antifreeze self-circulation mode.

[0108] Step 404, in response to determining that the temperature of the coolant in the antifreeze self-circulation mode is not lower than the second temperature threshold, the flow rate of the coolant in the antifreeze self-circulation mode is adjusted to a preset antifreeze minimum flow rate through the coolant flow rate adjustment device.

[0109] The second temperature threshold is lower than the first temperature threshold.

[0110] Step 405, in response to determining that the temperature of the coolant in the antifreeze self-circulation mode is lower than the second temperature threshold, adjusting the temperature of the coolant in the antifreeze self-circulation mode by a coolant temperature adjustment device.

[0111] Step 406 , in response to determining that the temperature of the coolant in the liquid cooling system in the bypass mode is not lower than the third temperature threshold, close the bypass mode and the antifreeze self-circulation mode, so that the dry cooler participates in the main circulation process of the liquid cooling system.

[0112] The third temperature threshold is higher than the first temperature threshold.

[0113] It can be seen from this embodiment that Figure 3 Compared with the corresponding embodiments, the process 400 of the antifreeze method applied to the dry cooler in this embodiment specifically illustrates the antifreeze control process of the dry cooler, and further the antifreeze effect of the dry cooler.

[0114] Continue to refer Figure 5 As an implementation of the methods shown in the above figures, the present disclosure provides an embodiment of an antifreeze device applied to a dry cooler.

[0116] In some optional implementations of this embodiment, the target state quantity includes temperature and flow rate; and the second determination unit 502 is further configured to: in response to determining that the temperature of the refrigerant flowing through the dry cooler during the main circulation process is lower than a first temperature threshold, and the flow rate is lower than a preset antifreeze minimum flow rate, start the antifreeze self-circulation mode and the bypass mode of the liquid cooling system relative to the dry cooler, wherein the preset antifreeze minimum flow rate represents the minimum flow rate to prevent the refrigerant from freezing, and in the bypass mode, the dry cooler is isolated from the main circulation process.

[0117] In some optional implementations of this embodiment, the preset adjustment device includes a refrigerant flow rate adjustment device; and a second determination unit 502, which is further configured to: determine the temperature of the refrigerant in the antifreeze self-circulation mode; in response to determining that the temperature of the refrigerant in the antifreeze self-circulation mode is not lower than the second temperature threshold, adjust the flow rate of the refrigerant in the antifreeze self-circulation mode to a preset antifreeze minimum flow rate through the refrigerant flow rate adjustment device, wherein the second temperature threshold is lower than the first temperature threshold.

[0118] In some optional implementations of this embodiment, the preset adjustment device includes a refrigerant temperature adjustment device; and a second determination unit 502, which is further configured to: in response to determining that the temperature of the refrigerant in the antifreeze self-circulation mode is lower than the second temperature threshold, adjust the temperature of the refrigerant in the antifreeze self-circulation mode through the refrigerant temperature adjustment device.

[0119] In some optional implementations of this embodiment, the second determination unit 502 is further configured to: control the heating amount of the coolant temperature adjustment device according to the temperature of the coolant in the antifreeze self-circulation mode.

[0121] In the present embodiment, an antifreeze device applied to a dry cooler is provided, and whether to perform the antifreeze self-circulation process of the dry cooler is controlled according to the target state quantity of the refrigerant flowing through the dry cooler in the main circulation corresponding to the liquid cooling system. During the antifreeze self-circulation process, the target state quantity of the refrigerant can be adjusted to achieve antifreeze of the refrigerant in the dry cooler, thereby improving the antifreeze effect of the dry cooler. Moreover, based on the active adjustment of the target state quantity of the refrigerant, the dry cooler is no longer limited to refrigerants with low freezing points such as ethylene glycol, thereby improving the applicability of the dry cooler to refrigerants. In particular, when water is used as the refrigerant, the energy loss caused by the high viscosity and low specific heat of ethylene glycol is reduced; compared with the corrosiveness and mild toxicity of ethylene glycol, water as a refrigerant improves safety.
