[0002] Natural cooling refers to the use of natural low-temperature air or water as a cooling medium to reduce the temperature in data centers and other facilities, thereby reducing energy consumption. Natural cooling can not only significantly reduce the energy consumption of data centers, but also help reduce carbon emissions. It is one of the important ways to achieve a green data center. At present, relying solely on mechanical refrigeration consumes huge amounts of energy, which not only increases operating costs, but also does not meet the current requirements of green and low-carbon development. At the same time, traditional heat dissipation methods are often inefficient and difficult to meet the growing heat dissipation needs of the computing cabin. This may cause the equipment temperature to be too high, affecting equipment performance and life, and has a greater impact on the environment.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figure 1-Figure 2 As shown, one of the purposes of the present invention is to provide a computing power cabin temperature control system based on a natural cooling source, including a data acquisition unit 10, a working mode setting unit 20, a mechanical refrigeration unit 30, a natural cooling source unit 40 and a mode detection unit 50; The data acquisition unit 10 is used to obtain the internal temperature of the computing cabin and the inlet temperature and outlet temperature of the heat exchanger, and at the same time collect the ambient temperature of the installation location of the computing cabin; The data acquisition unit 10 is connected to the control port of the computing cabin to collect parameter data of the computing cabin status panel in the control port, and then extracts the internal temperature of the computing cabin and the inlet and outlet temperatures of the heat exchanger, as well as the external environment temperature collected by the computing cabin surface temperature sensor from the parameter data. The specific steps are as follows: Connect to the Hash Pod control port: Use appropriate communication interfaces and protocols, such as serial ports, Ethernet, etc., to establish a connection with the Hash Pod control port to ensure that the connection is stable and reliable and capable of data transmission; Collect parameter data: Send instructions through the control port to request parameter data of the computing cabin status panel, receive and parse the returned data, and extract the required parameters, including the internal temperature of the computing cabin, the inlet and outlet temperatures of the heat exchanger, and the external ambient temperature.

[0019] The working mode setting unit 20 is used to set the mechanical cooling working mode and the natural cooling source working mode according to the performance parameters of the computing power cabin, and then determine whether to enter the mechanical cooling working mode and the natural cooling source working mode according to the ambient temperature; The working mode setting unit 20 includes a temperature setting module and a mode entry module; The temperature setting module is used to obtain the constant temperature data of the computing cabin's working requirements based on the performance parameters of the computing cabin, and then set the corresponding working conditions for the mechanical refrigeration working mode and the natural cooling source working mode according to the constant temperature data. The specific steps are as follows: Mechanical refrigeration working mode: According to the constant temperature data and the heat load of the computing power cabin, the start temperature and stop temperature of the mechanical refrigeration working mode are determined. When the internal temperature of the computing power cabin exceeds the set upper limit temperature, the mechanical refrigeration system is started, and when the temperature drops to the set lower limit temperature, the mechanical refrigeration system is stopped; Considering factors such as the refrigeration capacity and energy efficiency ratio of the mechanical refrigeration system, the working conditions should be adjusted reasonably to ensure that energy consumption is minimized while meeting the constant temperature requirements.

[0020] Natural cooling source working mode: Analyze the availability and stability of the natural cooling source, determine the applicable temperature range of the natural cooling source working mode, and use the natural cooling source to dissipate heat when the external ambient temperature is within a certain range; Based on the temperature, flow and other parameters of the natural cooling source, as well as the heat load of the computing cabin, the working conditions such as the inlet temperature, outlet temperature and air volume under the natural cooling source working mode are determined.

[0021] The mode entry module is used to compare the ambient temperature with the working conditions of the mechanical cooling working mode and the natural cooling source working mode. When the ambient temperature is within the working conditions of the mechanical cooling working mode, it is determined that the computing power cabin enters the mechanical cooling working mode. Conversely, when the ambient temperature is within the working conditions of the natural cooling source working mode, it is determined that the computing power cabin enters the natural cooling source working mode.

[0022] The mechanical refrigeration working mode in the working mode setting unit 20 is to control the air conditioning refrigeration device to automatically start running, the exhaust fan to automatically stop running, and the fresh air valve and the exhaust valve to automatically close; The working mode of the natural cooling source is to control the air conditioning refrigeration device to automatically stop running, the fresh air valve and the exhaust air valve to automatically open, and the exhaust fan to automatically start running.

[0023] The natural cooling source working mode in the working mode setting unit 20 uses air cooling to dissipate heat, and has two modes, namely natural convection and forced convection. The specific steps are as follows: Open the fresh air valve and exhaust valve, rely on the natural flow of air to dissipate heat, and continuously monitor parameters such as the internal temperature of the computing cabin, the inlet and outlet temperatures of the heat exchanger, and the external ambient temperature. If natural convection cannot meet the heat dissipation requirements and the internal temperature of the computing cabin rises to a certain threshold or the outlet temperature of the heat exchanger is close to the inlet temperature and higher than the expected temperature range, prepare to switch to forced convection mode.

[0024] The forced convection mode is activated by starting the exhaust fan to increase the air flow rate, adjusting the inlet / outlet size, fan speed and other parameters according to the actual heat dissipation requirements, and then continuously monitoring various temperature parameters to dynamically adjust the intensity of forced convection.

[0025] If the temperature drops to a certain level and stabilizes within a suitable range in forced convection mode, you can consider switching back to natural convection mode to reduce energy consumption.

[0026] The mechanical refrigeration unit 30 is used to dynamically adjust the refrigeration power according to the internal temperature when in the mechanical refrigeration working mode. The formula is as follows:

[0027] Where ∆T is the deviation between the internal temperature and the target temperature range, sets the initial cooling power of the mechanical refrigeration working mode, and the target range of temperature control. The target temperature range is [T tarmin ,T tarmax ],T taravg The average value of the target temperature range is T int is the internal temperature; When ∆T>0 and is large, it means that the internal temperature is much higher than the target temperature and the cooling power needs to be increased. The cooling power can be increased gradually according to a certain ratio. When ∆T is less than 0 and is relatively large, it means that the internal temperature is much lower than the target temperature and the cooling power needs to be reduced. Similarly, the cooling power can be gradually reduced according to a certain ratio. When ∆T is within a smaller range, the current cooling power can be kept unchanged.

[0028] The natural cooling source unit 40 is used to dynamically set the air flow rate when in the natural cooling source working mode, and at the same time set the stable temperature range of heat dissipation for the outlet temperature according to the inlet temperature, and then select the center value in the stable temperature range according to the internal temperature, and then analyze the air flow rate adjustment by combining the outlet temperature with the center value; The natural cooling source unit 40 includes a wind flow setting module and a rate adjustment module; The airflow setting module is used to dynamically set the airflow rate for heat dissipation in the computing power cabin according to the internal temperature combined with the inlet temperature when in the natural cooling source working mode, and to set the stable temperature range of heat dissipation according to the inlet temperature and the outlet temperature. The formula is as follows:

[0029] Among them, T int is the internal temperature of the computing cabin, T in is the inlet temperature of the heat exchanger, T out is the outlet temperature of the heat exchanger; According to ∆T int-in Adjust the air flow rate V, T threshold is the temperature threshold, T threshold1 is a positive temperature threshold, -T threshold2 A temperature threshold that is a negative number; When ∆T int-in >Tthreshold1 , indicating that the heat dissipation demand is high, and the air flow rate is greatly increased. The formula is:

[0030] Among them, V current is the current wind speed, k 1 is a larger adjustment factor; When T threshold2 <∆T int-in ≤T threshold1 , moderately increase the wind speed, the formula is:

[0031] Among them, k 2 is a moderate adjustment factor; When-T threshold2 ≤∆T int-in ≤-T threshold2 , keep the wind speed, then V=V current ; ∆T int-in <-T threshold2 , indicating possible overcooling, the wind speed can be appropriately reduced. The formula is:

[0032] Among them, k 3 is a smaller adjustment factor; According to the inlet temperature T in To set the outlet temperature stable range, a linear relationship can be used, such as: The lower limit of outlet temperature is

[0033] The upper limit of outlet temperature is

[0034] Among them, k 4 and k 5 It is the adjustment parameter determined according to the actual situation.

[0035] Continuously monitor temperature changes and continuously adjust the air flow rate and outlet temperature stability range based on new temperature data to ensure heat dissipation and temperature stability.

[0036] The rate adjustment module is used to select the center value in the stable temperature range according to the internal temperature, determine the temperature value that best matches the internal temperature as the center value, and then adjust the wind flow rate analysis based on the outlet temperature combined with the center value. When the outlet temperature is greater than the center value, the wind flow rate is increased. On the contrary, when the outlet temperature is less than the center value, the wind flow rate is reduced. According to the current stable temperature range, the central value is calculated by a simple average calculation. Then, the internal temperature of the computing power cabin is compared with the central value, and the temperature value that best matches the internal temperature is selected as the final central value. The best match here can be defined according to specific needs, and can be the best matching temperature determined based on historical experience.

[0037] The mode detection unit 50 is used to analyze the development trend of the outlet temperature in combination with the stable temperature range, and adjust the natural cooling source working mode to the mechanical refrigeration working mode in advance according to the development trend.

[0038] The mode detection unit 50 includes a trend analysis module and a mode adjustment module; The trend analysis module is used to analyze the development trend of the outlet temperature in combination with the stable temperature range; The mode adjustment module is used to adjust the natural cooling source working mode to the mechanical cooling working mode in advance when the outlet temperature development trend is about to exceed the stable temperature range. Conversely, when the outlet temperature development trend does not show that it will exceed the stable temperature range, it continues to monitor. The specific steps are as follows: Determine outlet temperature development trend: Continuously monitor outlet temperature changes over a period of time. This can be done by recording outlet temperature values ​​at multiple consecutive time points, such as recording the temperature at regular intervals to form a temperature sequence. Simple linear regression or other trend analysis methods can be used to determine outlet temperature development trends. Compare the development trend with the stable temperature range: Based on the obtained outlet temperature development trend, predict the outlet temperature value in the future, and compare the predicted value with the stable temperature range. If the predicted value exceeds the stable temperature range, it indicates that the development trend of the outlet temperature will exceed the stable temperature range. Mode switching decision: When the outlet temperature trend is about to exceed the stable temperature range, the natural cooling source working mode is adjusted to the mechanical cooling working mode in advance, the fresh air valve and exhaust valve are closed, the air conditioning refrigeration system is started, and the exhaust fan is stopped; When the outlet temperature trend does not show that it will exceed the stable temperature range, monitoring is continued without switching modes.

[0039] The mode detection unit 50 also includes a static elimination module; The static electricity elimination module is used to monitor the static electricity level in the computing power cabin and automatically adjust the static electricity elimination work intensity according to the static electricity level. The specific steps are as follows: Install static electricity sensors: Install static electricity sensors at appropriate locations in the computing cabin to ensure that the static electricity level in the entire cabin can be accurately monitored; Set static electricity level threshold: determine different static electricity level ranges and set corresponding static electricity elimination work intensity for each range. You can set low static electricity level range, medium static electricity level range and high static electricity level range, and correspond to three static electricity elimination work intensities of weak, medium and strong respectively; Real-time monitoring of static electricity levels: The static electricity sensor continuously monitors the static electricity level in the computing power cabin and transmits the monitored static electricity value to the control end in real time; Comparing the static electricity level with the threshold: The control end compares the received static electricity value with the set static electricity level threshold to determine the range of the current static electricity level; Adjust the working intensity of static elimination: Automatically adjust the working intensity of static elimination equipment according to the range of static electricity level; When the static electricity level is in the low static electricity level range, reduce the working intensity of the static electricity elimination equipment to save energy; When the static electricity level is in the medium static electricity level range, maintain a medium static electricity elimination work intensity; When the static electricity level is in the high static electricity level range, the working intensity of the static electricity elimination equipment is increased to ensure that the static electricity can be eliminated quickly.
