[0039] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0040] In order to solve the technical problem existing in the present invention, the present invention provides a system for regulating the temperature of a cabinet, such as Figure 2 Shown is a schematic diagram of the structure of the system for regulating cabinet temperature provided by the present invention.

[0041] The system for regulating the temperature of the cabinet includes a cabinet 1, one side of which is connected to an air conditioner 2; the air conditioner 2 is provided with an internal fan 21 on the connection surface with the cabinet 1, and the air conditioner 2 is also provided with an external fan 22. In specific implementation, the server 3 is installed in the cabinet 1, and the cabinet 1 and the air conditioner 2 can be an integral structure or a separate structure. When the air conditioner 2 is mechanically refrigerated, cold air can be blown out from the "inside air outlet" internal fan 21 to the server 3 in the cabinet 1 for cooling, and then enter the inside of the air conditioner through the "inside air intake" and blow out the cold air through the evaporator 27 for heat exchange, and the cycle continues. When the cabinet 1 is cooled by a low-temperature natural cold source, the "external air intake" can be introduced through the external fan 22, and the "outgoing air" can be blown out through the condenser 28.

[0042] The air conditioner 2 is also provided with a gas injection assembly 23 on the connection surface with the cabinet 1. Figure 2 As shown, it is arranged on the inner side 2 of the air conditioner, and is used to switch the direction of the injection gas and the induced gas, and is used to inject the mixed air obtained by mixing the air outside the cabinet with the air inside the cabinet into the cabinet 1 to adjust the temperature value inside the cabinet 1. The air conditioner 2 is also provided with a first temperature sensor 24, such as a return air temperature sensing package, which is used to detect the ambient temperature value inside the cabinet 1 and compare it with the set target temperature value to determine the object of the injection gas and the induced gas. The air conditioner 2 is also provided with a second temperature sensor 25, such as an outer ring temperature sensing package, which is used to detect the external environment temperature value and compare it with the target temperature value of the external environment to control whether the air conditioner 2 is turned on or off.

[0043] By monitoring the temperature value inside the cabinet 1 and the temperature value of the external environment at any time through the first temperature sensor 24 and the second temperature sensor 25, and adjusting the injection direction and injection duration of the gas injection assembly 23 at any time according to the target temperature value, the temperature value inside the cabinet 1 can be maintained within a reasonable temperature range for the operation of the server 3, thereby ensuring the reliable operation of the server 3.

[0044] The gas injection assembly 23 includes a gas reversing device 231, an air pump 232 and an injector 233 connected in sequence. The gas reversing device 231 includes a two-way valve group or a four-way valve. In specific implementation, the air pump 232 provides power, and the gas reversing device 231 is used to switch the directions of the injection gas and the induced gas, and introduce them into the injector 233. Then, the injector 233 mixes the injection gas and the induced gas and injects them into the cabinet 1 to adjust the temperature value in the cabinet 1.

[0045] In specific implementation, when the cooling demand is large, Figure 3 , Figure 4 As shown, by adjusting the four-way valve or the two-way valve group, the switch between the injection gas being the air outside the cabinet and the induced air being the air inside the cabinet can be realized. Figure 3 As shown, C and D are connected, E and S are connected, and the air outside the cabinet passes through the cabinet external air inlet through D and C into the air pump 232 and is blown to the ejector 233. Due to the ejection principle, the air inside the cabinet passes through the cabinet internal air inlet through S and E into the ejector pipe, and is mixed with the air outside the cabinet in the ejector 233 before being ejected into the cabinet. Figure 4 As shown, through the cooperation of two-way valve A and two-way valve B, the air outside the cabinet passes through the air inlet outside the cabinet through the two-way valve A and enters the air pump 232 to blow toward the ejector 233. Due to the ejection principle, the air inside the cabinet passes through the air inlet inside the cabinet through the two-way valve B and enters the ejection pipe, where it is mixed with the air outside the cabinet in the ejector 233 and then ejected into the cabinet.

[0046] When the cooling demand is small, the injection gas is the air inside the cabinet, and the induced air is the air outside the cabinet. Figure 3 , C and S are connected, E and D are connected, the air inside the cabinet passes through the air inlet inside the cabinet through S and C into the air pump and blows to the ejector. Due to the ejection principle, the air outside the cabinet passes through the air inlet outside the cabinet through D and E into the ejector pipe, mixes with the air inside the cabinet in the ejector 233, and then is ejected into the cabinet. Figure 4 As shown, through the cooperation of two-way valve A and two-way valve B, the air inside the cabinet enters the air pump 232 through the air inlet inside the cabinet via the two-way valve B and is blown to the ejector 233. Due to the ejection principle, the air outside the cabinet enters the ejection pipe through the air inlet outside the cabinet via the two-way valve A and is mixed with the air inside the cabinet in the ejector 233 and then sprayed into the cabinet.

[0047] By making reasonable use of the gas injection assembly 23, which airflow is used as the injection gas of the injector 233 and which is the induced gas according to the temperature inside and outside the cabinet and the demand for cooling capacity in the cabinet, and the direction switching is achieved through the four-way valve / two-way valve group, the low-temperature cold source of the external environment can be maximized to adjust the temperature value in the cabinet to the target temperature value, so that the temperature value in the cabinet 1 is uniform and appropriate. At this time, the air conditioner 2 can be shut down, so that the air conditioner 2 does not need to run for a long time, thereby prolonging the service life of the server 3 and the air conditioner 2.

[0048] In some embodiments, the system for regulating the cabinet temperature also includes a third temperature sensor 26, such as an infrared detector, which is arranged on the cabinet 1 or on the air conditioner 2, and is used to detect the local high point value of the temperature in the cabinet 1. If the local temperature value in the cabinet 1 is too high, the injection direction of the gas injection assembly 23 can be adjusted to thereby adjust the temperature value to prevent the local temperature value from being too high.

[0049] In other embodiments, the cabinet 1 is further provided with a wind pressure sensor 11 and a hydrogen exhaust fan 12. The wind pressure sensor 11 is used to detect the pressure value in the cabinet 1, and the hydrogen exhaust fan 12 is used to exhaust the hydrogen in the cabinet 1. In specific implementation, when the gas injection assembly 23 runs for a long time, it will cause a high pressure in the cabinet 1, so it is necessary to balance the pressure values ​​inside and outside the cabinet 1, and the wind pressure sensor 11 is used to detect the pressure value in the cabinet 1, control the opening of the hydrogen exhaust fan 12, exhaust the hydrogen in the cabinet 1, and then balance the pressure values ​​inside and outside the cabinet 1.

[0050] The present invention also provides a method for controlling the temperature of a cabinet, which is applied to the system for controlling the temperature of the cabinet, referring to Figure 5 , is a flow chart of a method for controlling cabinet temperature provided by an embodiment of the present invention, the method comprising:

[0051] S110: Collecting the outdoor ambient temperature value and the indoor ambient temperature value at the current moment; the outdoor ambient temperature value is the detected external ambient temperature value, and the indoor ambient temperature value is the ambient temperature value inside the cabinet 1.

[0052] In specific implementation, the first temperature sensor 24 can detect the ambient temperature value inside the cabinet 1 at fixed intervals, and the second temperature sensor 25 can detect the external ambient temperature value, that is, the current outdoor ambient temperature value T can be collected. 外环 , Indoor ambient temperature value T 内环 .

[0053] S120: Obtain a preset outdoor target ambient temperature value and a preset indoor target ambient temperature value, and compare the outdoor ambient temperature value with the outdoor target ambient temperature value. If the outdoor ambient temperature value is less than the outdoor target ambient temperature value, control the compressor of the air conditioner 2 and the outdoor fan 22 of the air conditioner 2 to stop running, and control the indoor fan 21 of the air conditioner 2 to run.

[0054] The target ambient temperature value outside is recorded as T 外目标 , the indoor target ambient temperature is recorded as T 内目标 , the outdoor ambient temperature value T detected at the current moment in step S110 外环and the outdoor target ambient temperature value T 外目标 Compare and determine T 外环 <T 外目标 Is it satisfied? When T 外环 <T 外目标 If the load demand is not met, air conditioner 2 can decide whether to start the machine according to the load demand. 外环 <T 外目标 When the conditions are met, the compressor of the air conditioner and the external fan 22 of the air conditioner stop running, and the internal fan 21 of the air conditioner continues to run.

[0055] S130: Compare the indoor ambient temperature value and the indoor target ambient temperature value, and determine whether to control the gas injection assembly 23 to operate for a preset time period to adjust the indoor ambient temperature value according to the comparison result.

[0056] In a specific implementation, the indoor ambient temperature value T 内环 and the indoor target ambient temperature value T 内目标 The comparison is performed, and the cooling demand is determined according to the comparison result. If the cooling demand is large, that is, the cabinet 1 needs to be cooled, the gas injection assembly 23 can be used to mix the low-temperature natural cooling source with the high-temperature air in the cabinet and inject it into the cabinet 1 according to the injection principle to cool the cabinet 1, so that the temperature in the cabinet 1 is uniform and appropriate. If the cooling demand is small, the air pump 232 can be turned off.

[0057] In one embodiment, comparing the indoor ambient temperature value with the indoor target ambient temperature value, and determining whether to control the gas injection assembly to operate for a preset time period to adjust the indoor ambient temperature value according to the comparison result, includes:

[0058] When the gas injection assembly 23 includes an air pump 232, compare whether the indoor ambient temperature value is less than a first temperature value. If so, turn off the air pump 232; if not, turn on the air pump 232; the first temperature value is the indoor target ambient temperature value minus a first floating temperature value.

[0059] In specific implementation, if T 内环 At 20℃, T 内目标 is 24°C, the range of the first floating temperature value is 0-5°C, if the first floating temperature value is 2°C, the first temperature value is 22°C, then T 内环 <22°C, turn off the air pump 232. If not, turn on the air pump 232 and proceed to the next step. Setting the range of floating temperature value is to increase the buffer space and avoid frequent adjustments.

[0060] In yet another embodiment, after starting the air pump 232, the method further includes:

[0061] When the gas injection assembly 23 includes a gas reversal device 231 and an injector 233, the indoor ambient temperature value is compared to see whether it is greater than a second temperature value. If so, the first injection gas and the first induced gas are mixed in the injector 233 through the gas reversal device 231 and then sprayed into the cabinet 1; the first injection gas is the air outside the cabinet, and the first induced gas is the air inside the cabinet; the second temperature value is the indoor target ambient temperature value plus a second floating temperature value.

[0062] Compare whether the indoor ambient temperature value is greater than the second temperature value. If not, the second injection gas and the second induced gas are mixed in the injector 233 through the gas reversing device 231 and then sprayed into the cabinet 1; the second injection gas is the air inside the cabinet, and the second induced gas is the air outside the cabinet.

[0063] In specific implementation, when the indoor ambient temperature value is greater than the second temperature value, it means that the load is large and the cooling demand is large. Figure 3 , Figure 4 As shown, by adjusting the four-way valve or the two-way valve group, the first injection gas is the air outside the cabinet, and the first induced air is the air inside the cabinet. Figure 3 As shown, C and D are connected, E and S are connected, and the air outside the cabinet passes through the cabinet external air inlet through D and C into the air pump 232 and is blown to the ejector 233. Due to the ejection principle, the air inside the cabinet passes through the cabinet internal air inlet through S and E into the ejector pipe, and is mixed with the air outside the cabinet in the ejector 233 before being ejected into the cabinet. Figure 4 As shown, through the cooperation of two-way valve A and two-way valve B, the air outside the cabinet passes through the air inlet outside the cabinet through the two-way valve A and enters the air pump 232 to blow toward the ejector 233. Due to the ejection principle, the air inside the cabinet passes through the air inlet inside the cabinet through the two-way valve B and enters the ejection pipe, where it is mixed with the air outside the cabinet in the ejector 233 and then ejected into the cabinet 1.

[0064] Specifically, when the indoor ambient temperature is not greater than the second temperature value, the load is small and the cooling demand is small. The second injection gas is the air inside the cabinet, and the second induced air is the air outside the cabinet. Figure 3 , C and S are connected, E and D are connected, the air inside the cabinet passes through the cabinet air inlet through S and C into the air pump 232 and blows toward the ejector 233. Due to the ejection principle, the air outside the cabinet passes through the cabinet air inlet through D and E into the ejector pipe, mixes with the air inside the cabinet in the ejector 233, and then is ejected into the cabinet 1. For example Figure 4As shown, through the cooperation of two-way valve A and two-way valve B, the air inside the cabinet enters the air pump 232 through the air inlet inside the cabinet through the two-way valve B and blows toward the ejector 233. Due to the ejection principle, the air outside the cabinet enters the ejection pipe through the air inlet outside the cabinet through the two-way valve A and is mixed with the air inside the cabinet in the ejector 233 and then ejected into the cabinet 1. The range of the first floating temperature value is 0-5°C, and the range of the second floating temperature value can be 0-8°C.

[0065] By rationally utilizing the gas injection assembly 23, the injection gas and the induced gas are adjusted according to the temperature inside and outside the cabinet 1, and mixed injection is performed through the injector 232, so as to maximize the utilization of the low-temperature cold source of the external environment, and then adjust the temperature value in the cabinet 1 to reach the target temperature value, avoid the temperature in the cabinet 1 being too high or too low, make the temperature value in the cabinet 1 uniform and appropriate, provide a suitable working environment for the server 3, reduce the fluctuation of the ambient temperature value in the cabinet 1, and ensure the reliable operation of the server 3.

[0066] In specific implementation, when the air pump 232 and the injector 233 are in operation, it also includes: detecting higher temperature points in the cabinet 1 through the third temperature sensor 26, and adjusting the gas injection assembly 23 to spray mixed air into the high temperature area according to the detection result, thereby reducing the temperature value in the cabinet 1 and preventing the local temperature value from being too high.

[0067] The gas injection assembly 23 runs for a preset period of time, such as 5 minutes, and then detects the temperature value again, and performs the above cycle according to corresponding judgment conditions to achieve monitoring and dynamic adjustment of the temperature.

[0068] In a specific embodiment, after comparing the indoor ambient temperature value with the indoor target ambient temperature value, and determining whether to control the gas injection assembly 23 to operate for a preset time period to adjust the indoor ambient temperature value according to the comparison result, the method further includes:

[0069] In the case where the system for controlling the temperature of the cabinet further includes a hydrogen exhaust fan 12, the wind pressure value in the cabinet 1 is detected to obtain a wind pressure measurement value. If the wind pressure measurement value is greater than a first target wind pressure value, the hydrogen exhaust fan 12 is turned on; if the wind pressure measurement value is less than the first target wind pressure value, it is determined whether the wind pressure measurement value is less than a second target wind pressure value; if the wind pressure measurement value is less than the second target wind pressure value, the hydrogen exhaust fan 12 is turned off; if the wind pressure measurement value is not less than the second target wind pressure value, the wind pressure value in the cabinet 1 is continuously detected.

[0070] Figure 6 A schematic diagram of a method for controlling the temperature of a cabinet according to a specific embodiment of the present invention is provided. Figure 6When the gas injection assembly 23 runs for a long time, it will cause a high pressure in the cabinet 1. Therefore, it is necessary to balance the pressure values ​​inside and outside the cabinet 1. The pressure value inside the cabinet 1 is detected by the wind pressure sensor 11, and the hydrogen exhaust fan 12 is controlled to open to exhaust the hydrogen in the cabinet 1, thereby balancing the pressure values ​​inside and outside the cabinet 1.

[0071] In a specific embodiment, if the first target wind pressure value is 30Pa and the second target wind pressure value is 5Pa, if the wind pressure measurement value P 风压 >30Pa, indicating that the pressure value in the cabinet 1 is high and needs to be reduced, and the exhaust fan 12 is turned on. 风压 <5Pa, it can be considered that the pressure inside and outside the cabinet 1 is balanced, and the exhaust fan 12 can be turned off.
