[0050] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments based on the embodiments are intended to be used to explain the present application and cannot be understood as limiting the present application.

[0051] References to "one embodiment" or "an example" or "an example" in this specification mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment disclosed in the present application. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0052] Traditional dry coolers have the disadvantages of poor heat exchange effect in harsh environments and high maintenance costs. After research, the applicant of this application found that the core of the traditional dry cooler is eroded by rainwater for a long time when it is in a rainy and humid environment for a long time. The calcium, magnesium ions and carbonates in the rainwater cause the core to be corroded and scaled, which seriously affects the heat exchange effect of the dry cooler and increases the maintenance cost of the dry cooler. In this regard, the applicant of this application proposes that by periodically detecting the liquid level of the liquid storage tank and the relative humidity of the environment, and when the relative humidity of the environment is greater than or equal to the preset humidity threshold, the additional spray group and evaporation group are controlled to dehumidify the dry cooler, which can effectively prevent moisture from causing corrosion and scaling of the dry cooler core, thereby improving the heat exchange effect of the dry cooler and reducing the maintenance cost of the dry cooler.

[0053] The applicant of this application also found that the traditional dry cooler is prone to frost in the extremely cold environment in winter, which seriously affects the heat exchange effect of the dry cooler and increases the maintenance cost of the dry cooler; when there is no temperature gradient between the dry cooler and the external environment, it is almost impossible to exchange heat with the external environment, resulting in extremely poor heat exchange effect. In this regard, the applicant of this application proposes to control the working state of the additional spray group and evaporation group by detecting the ambient temperature, the inlet temperature and the outlet temperature of the dry cooler, so as to control the ambient temperature of the dry cooler with the help of the additional spray group and evaporation group, thereby improving the heat exchange effect of the dry cooler and reducing the maintenance cost of the dry cooler. In addition, by adding a water treatment group to treat the tap water and then replenishing it into the additional liquid storage tank, it is convenient for the spray group to use the treated water to control the ambient temperature of the dry cooler, avoid corrosion of the dry cooler core, and further reduce the maintenance cost of the dry cooler.

[0054] As a first aspect of an embodiment of the present application, a control method for a dry cooler unit is provided, wherein the dry cooler unit comprises a dry cooler, a liquid storage tank, a water treatment group, a spray group, and an evaporation group, wherein the water treatment group, the spray group, and the evaporation group are all connected to the liquid storage tank, such as Figure 1 As shown, the method includes the following steps which are performed periodically:

[0055] Step S110, detecting the liquid level of the liquid storage tank and the relative humidity of the environment;

[0056] Step S120, when the liquid level is less than a preset liquid level threshold, controlling the water treatment group and the spray group to replenish liquid to the liquid storage tank;

[0057] Step S130, when the relative humidity of the environment is greater than or equal to a preset humidity threshold, controlling the spray group and the evaporation group to dehumidify the dry cooler;

[0058] Step S140, when the ambient relative humidity is less than a preset humidity threshold, detect the ambient temperature, the inlet liquid temperature and the outlet liquid temperature of the dry cooler, and control the working states of the spray group and the evaporation group according to the ambient temperature, the inlet liquid temperature and the outlet liquid temperature.

[0059] Among them, the dry cooler unit and the control method thereof provided in the embodiment of the present application are used to perform heat exchange for data center computing equipment or energy storage batteries in the liquid cooling unit in an immersion liquid cooling system. The embodiment of the present application will not elaborate on the liquid cooling unit here.

[0060] Among them, the evaporation group may include a humidity sensor for detecting the relative humidity of the environment, the spray group may include a temperature sensor for detecting the ambient temperature, the dry cooler may be provided with a temperature sensor for detecting the inlet liquid temperature and the outlet liquid temperature, and the liquid storage tank may be provided with a liquid level sensor for detecting the liquid level.

[0061] It is understood that if the liquid level is not less than the preset liquid level threshold, the process can jump directly to step S130 or step S140. After step S130 or step S140, in response to the arrival of the next cycle, the control method of the dry cooler unit provided in the embodiment of the present application is continued.

[0062] The present embodiment of the application does not specifically limit the preset liquid level threshold and the preset humidity threshold. For example, the preset liquid level threshold can be set according to the cavity height of the liquid storage tank, and the preset humidity threshold can be 95%, etc. The present embodiment of the application does not specifically limit the cycle length of executing steps S110-S140. For example, it can be 2 minutes, 3 minutes, etc.

[0063] H and Z represent the relative humidity of the environment and the preset humidity threshold, respectively. When H≥Z, it means that the relative humidity in the air is high and there is a risk of water accumulation in the dry cooler. At this time, the spray group and the evaporation group are controlled to dehumidify the dry cooler. When H<Z, it means that the relative humidity in the air is low and will not cause water accumulation in the dry cooler. At this time, the ambient temperature, the inlet and outlet temperatures of the dry cooler can be further detected to identify the temperature difference between the dry cooler and the environment, so as to cool down or defrost the dry cooler through the spray group and the evaporation group.

[0064] In the control method of the dry cooler unit provided in the embodiment of the present application, a dry cooler unit including a dry cooler, a liquid storage tank, a water treatment group, a spray group and an evaporation group is formed. By periodically detecting the liquid level of the liquid storage tank and the relative humidity of the environment, and when the relative humidity of the environment is greater than or equal to the preset humidity threshold, the additional spray group and the evaporation group are controlled to dehumidify the dry cooler, which can effectively avoid the corrosion and scaling of the dry cooler core caused by moisture, thereby improving the heat exchange effect of the dry cooler and reducing the maintenance cost of the dry cooler. By detecting the ambient temperature, the inlet temperature and the outlet temperature of the dry cooler, the working state of the additional spray group and the evaporation group is controlled, so as to control the ambient temperature of the dry cooler with the help of the additional spray group and the evaporation group, thereby improving the heat exchange effect of the dry cooler and reducing the maintenance cost of the dry cooler. In addition, by adding a water treatment group to treat the tap water and then replenishing it into the additional liquid storage tank, it is convenient for the spray group to use the treated water to control the ambient temperature of the dry cooler, avoid corrosion of the dry cooler core, and further reduce the maintenance cost of the dry cooler.

[0065] In some embodiments, the working states of the spray group and the evaporation group are controlled according to the ambient temperature, the liquid inlet temperature and the liquid outlet temperature (ie, those involved in step S140), such as Figure 2 As shown, it may include:

[0066] Step S210, when the ambient temperature is greater than a first preset temperature threshold, controlling the working state of the spray group according to the ambient temperature, the liquid inlet temperature and the liquid outlet temperature;

[0067] Step S220, when the ambient temperature is less than or equal to the second preset temperature threshold, controlling the working states of the spray group and the evaporation group; wherein the second preset temperature threshold is less than the first preset temperature threshold.

[0068] Th, X, and C represent the ambient temperature, the first preset temperature threshold, and the second preset temperature threshold, respectively. When Th>X, it means that the ambient temperature is higher than the reasonable working temperature of the dry cooler. At this time, it is difficult for the dry cooler to naturally transfer heat through the environment, and the spray group is needed to cool down the working environment of the dry cooler. When Th≤C, it means that the ambient temperature is lower than the reasonable working temperature of the dry cooler, and there is a risk of frost on the dry cooler. At this time, the spray group and the evaporation group need to be used to defrost the dry cooler.

[0069] In some embodiments, the spray group includes a liquid pump, a pipeline and a high-density atomizing nozzle, and the working state of the spray group is controlled according to the ambient temperature, the liquid inlet temperature and the liquid outlet temperature (that is, the step 210 involved), such as Figure 3 As shown, it may include:

[0070] Step S310, controlling the liquid pump to start, so that the liquid pump sprays the deionized water in the liquid storage tank to the dry cooler through the pipeline and the high-density atomizing nozzle; and

[0071] Step S320, when the temperature difference between the liquid inlet temperature and the liquid outlet temperature is less than a preset temperature difference threshold, an operating frequency control parameter is calculated according to the ambient temperature, the liquid outlet temperature, the temperature difference and a preset control algorithm, and the operating frequency of the liquid pump is controlled according to the operating frequency control parameter.

[0072] The liquid pump sprays the deionized water in the liquid storage tank to the dry cooler through the pipeline and the high-density atomizing nozzle, thereby utilizing enthalpy humidification to cool down the working environment of the dry cooler.

[0073] The embodiment of the present application does not impose any special limitation on the initial operating frequency when the liquid pump is turned on. For example, the initial operating frequency can be controlled to 30 Hz.

[0074] Among them, the embodiment of the present application does not make a specific limitation on the number of high-density atomizing nozzles. For example, it can be determined according to the following formula: N = (S / R) * (Q / L), wherein N, S, R, Q, and L respectively represent the number of high-density atomizing nozzles, the cross-sectional area of ​​the core of the dry cooler, the atomization radius of a single high-density atomizing nozzle, the flow rate of a single high-density atomizing nozzle, and the design value of the water supply flow rate in the immersion liquid cooling system.

[0075] Among them, the embodiment of the present application does not make any specific limitation on the diameter of the pipeline. For example, it can be determined according to the following formula: D=α√qv / v, wherein D, α, qv, and v respectively represent the diameter of the pipeline, the preset proportional coefficient, the fluid flow rate in the pipeline, and the fluid flow rate in the pipeline.

[0076] ΔT and Y represent the temperature difference between the inlet and outlet temperatures and the preset temperature difference threshold, respectively. When ΔT<Y, it means that the dry cooler cannot currently meet the heat dissipation demand, so the operating frequency of the liquid pump in the spray group is controlled to cool down the working environment of the dry cooler more quickly by using the enthalpy humidification method. It can be understood that when ΔT≥Y, it means that the dry cooler can still meet the heat dissipation demand, and the heat dissipation capacity is converging to a positive trend, so no operation can be taken.

[0077] In some embodiments, the preset control algorithm includes the following formula (1):

[0078] F = Round (ΔT - Th / Tc) (1);

[0079] In formula (1), F represents the operating frequency control parameter, ΔT represents the temperature difference, Tc represents the liquid outlet temperature, and Round(...) represents a rounding function.

[0080] As described above, when Th≤C, it means that the ambient temperature is lower than the reasonable operating temperature of the dry cooler, and the dry cooler is at risk of frosting. At this time, the dry cooler needs to be defrosted with the help of the spray group and the evaporation group. Accordingly, in some embodiments, the spray group includes an antifreeze storage tank, a liquid pump, a pipeline and a high-density atomizing nozzle, and the evaporation group includes a hot air blower and an air duct. When the ambient temperature is less than or equal to the second preset temperature threshold, the working state of the spray group and the evaporation group is controlled (i.e., involved in step S220), as shown in FIG. Figure 4 As shown, this may include:

[0081] Step S410, when the ambient temperature is less than or equal to the second preset temperature threshold, controlling the hot air blower to turn on and keep on for a first preset time, so that the hot air blower delivers hot air to the dry cooler through the air duct; and

[0082] Step S420, controlling the valve of the antifreeze storage tank and the liquid pump to open and continue for a second preset time period, so that the liquid pump sprays the antifreeze in the antifreeze storage tank to the dry cooler through the pipeline and the high-density atomizing nozzle.

[0083] The embodiment of the present application does not specifically limit the air duct in the evaporation group. For example, the air duct can be a square pipe and its cross-sectional area is designed according to the following formula: S = (qv / v)^2, where S, qv, and v represent the cross-sectional area, air volume, and wind speed of the air duct in sequence. Determining the cross-sectional area of ​​the air duct according to the air volume and wind speed can defrost the dry cooler more quickly.

[0084] Among them, the embodiment of the present application does not make any specific limitation on the first preset time length and the second preset time length. For example, the first preset time length and the second preset time length can be 5 minutes and 30 seconds respectively, so as to defrost the dry cooler more safely.

[0085] In some embodiments, the water treatment group includes a water treatment device, a constant pressure tank, a booster pump, a vacuum degassing tank and a pipeline. When the liquid level is less than a preset liquid level threshold, the water treatment group is controlled to replenish the liquid to the liquid storage tank (i.e., the step S120 involved). Figure 5 As shown, it may include:

[0086] Step S510, when the liquid level is less than a preset liquid level threshold, controls the valve of the constant pressure tank and the booster water pump to open, so that the booster water pump transports the deionized water in the water treatment device to the vacuum degassing tank through the pipeline for degassing, and transports the deionized water after degassing to the liquid storage tank through the pipeline.

[0087] Among them, the valve of the constant pressure tank and the booster water pump are opened, so that the booster water pump transports the deionized water in the water treatment device to the vacuum degassing tank through the pipeline for degassing treatment, and transports the deionized water after degassing to the liquid storage tank through the pipeline. The subsequent spray group uses the treated water to control the ambient temperature of the dry cooler to avoid corrosion of the dry cooler core, thereby further reducing the maintenance cost of the dry cooler.

[0088] The applicant of the present application further proposes that the dry cooler is designed as one standby and one in use, which can further improve the safety of the dry cooler unit and reduce the maintenance cost of the dry cooler. In some embodiments, the dry cooler includes two units, and the two dry coolers are respectively in the main state and the standby state. When the relative humidity of the environment is greater than or equal to the preset humidity threshold, the spray group and the evaporation group are controlled to dehumidify the dry cooler (i.e., the step S130 involved). Figure 6As shown, it may include:

[0089] Step S610, switching the main state and the standby state of the two dry coolers;

[0090] Step S620, controlling the spray group and the evaporation group to dehumidify the dry cooler in the standby state after switching;

[0091] Step S630, switching the active state and the standby state of the two dry coolers again.

[0092] It can be understood that being in the main state means being in use, and being in the standby state means being out of use. If the two dry coolers A and B are currently in the main state and the standby state respectively, then after the main state and the standby state of the two dry coolers A and B are switched, the two dry coolers A and B are in the standby state and the main state respectively. After the main state and the standby state of the two dry coolers A and B are switched again, the two dry coolers A and B are in the main state and the standby state respectively.

[0093] In some embodiments, the spray group includes an anhydrous ethanol storage tank, a liquid pump, a pipeline and a high-density atomizing nozzle, the evaporation group includes a hot air blower and an air duct, and the spray group and the evaporation group are controlled to dehumidify the dry cooler in the standby state after switching (i.e., involved in step S620), such as Figure 7 As shown, it may include:

[0094] Step S710, controlling the hot air blower to turn on and keep it on for a first preset time, so that the hot air blower delivers hot air to the dry cooler in the standby state after switching through the air duct;

[0095] Step S720, controlling the valve of the anhydrous ethanol storage tank and the liquid pump to open and keep opening for a second preset time, so that the liquid pump sprays the anhydrous ethanol in the anhydrous ethanol storage tank through the pipeline and the high-density atomizing nozzle to the dry cooler in the standby state after switching.

[0096] Among them, the hot air blower is controlled to be turned on and maintained for a first preset time, so that the hot air blower can deliver hot air to the dry cooler in a standby state after switching through the air duct, which can heat and evaporate excess moisture in the air. At the same time, the valve and the liquid pump of the anhydrous ethanol storage tank are controlled to be turned on and maintained for a second preset time, so that the liquid pump can spray the anhydrous ethanol in the anhydrous ethanol storage tank to the dry cooler in a standby state after switching through the pipeline and the high-density atomizing nozzle, which can take away a small amount of residual moisture in the air and the heat brought by the hot air blower through volatilization, and can also play an anti-corrosion and sterilization role.
