Description

Technical Field

[0001] The present invention relates to the technical field of equipment heat dissipation, and in particular to a heat dissipation method and device based on a rack-type cooling distribution unit. Background Art

[0002] With the development of science and technology, information technology and data technology have also developed more rapidly. In the current data room, various equipment and cabinets have also been updated, but due to the improvement of the performance of various equipment components, the power consumption and heat generation of different equipment have also increased significantly, making the existing equipment unable to meet the cooling requirements of the cabinet. The current cooling method usually uses air cooling or water cooling, but the current control method of cooling is not intelligent enough, which makes the cooling control of the equipment not accurate enough, which easily leads to overheating of the equipment and low safety. Summary of the invention

[0003] Therefore, an embodiment of the present invention provides a heat dissipation method based on a rack-type cooling distribution unit, so that the heat dissipation of the equipment is more intelligent.

[0004] To solve the above problems, the present invention provides a heat dissipation method based on a rack-mounted cooling distribution unit, including: obtaining daily parameters of a recording device, and establishing a historical database based on the daily parameters; obtaining the temperature inside the current device to obtain a first temperature; obtaining the number of electronic devices loaded inside the current device to obtain a first number, and obtaining the number of electronic devices that are turned on to obtain a second number; calculating a first reference value based on the first number and the second number; querying the historical database accordingly based on the first temperature and the first reference value; if the corresponding historical first temperature and the historical first reference value are queried, obtaining the refrigerant parameters under the corresponding situation to perform a first heat dissipation adjustment on the device; if the corresponding values ​​of the first temperature and the first reference value are not queried, searching the historical database for similar temperature values ​​and similar reference values ​​respectively based on the first temperature and the first reference value; and performing a second heat dissipation adjustment on the device based on the similar temperature values ​​and similar reference values ​​and in combination with the historical database.

[0005] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: by setting the internal temperature of the device, the number of devices, and the number of devices turned on, it is convenient to control the internal situation of the device later, and at the same time, the temperature of the device can be better controlled, and better heat dissipation can be performed. At the same time, by comparing and querying historical situations, the heat dissipation adjustment can be made more quickly for the heat dissipation situation that is the same as the historical situation, so that the temperature inside the device can be better controlled, and the internal temperature of the device can be adjusted more intelligently to ensure the stability of the device operation. At the same time, by taking similar situations as a reference when the same historical situation is not obtained, different heat dissipation adjustments can be made, so that the adjustment of the internal situation of the device is more accurate, and it can also adapt to different equipment conditions, ensuring the stable operation of the equipment under different conditions, avoiding the overload of the equipment caused by excessive temperature, and then affecting the safety of the equipment, while ensuring the safety of the equipment, the controllability and intelligence of the heat dissipation of the equipment are improved.

[0006] In an example of the present invention, calculating the first reference value according to the first quantity and the second quantity includes: the first reference value is a ratio of the first quantity to the second quantity.

[0007] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: by setting the first reference value as the ratio of the number of devices to the number of devices turned on, the equipment situation inside the entire cabinet can be more completely reflected, so that the subsequent temperature adjustment of the equipment inside the cabinet is more in line with the actual situation, and the stable adjustment inside the cabinet is more intelligent, avoiding the situation where the temperature is too high and the equipment is overloaded.

[0008] In one example of the present invention, if the corresponding historical first temperature and the historical first reference value are queried, obtaining the refrigerant parameters in the corresponding situation to perform the first heat dissipation adjustment on the equipment also includes: the refrigerant parameters include: a first refrigerant flow rate and a first refrigerant temperature; controlling the refrigerant flow rate in the current equipment to reach the first refrigerant flow rate, controlling the refrigerant temperature in the current equipment to reach the first refrigerant temperature, and performing temperature detection on the equipment again after both are reached to obtain a second temperature; comparing the second temperature with the detection temperature threshold to obtain a comparison result, and judging whether a temperature warning is needed based on the comparison result.

[0009] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: by setting the refrigerant flow rate and refrigerant temperature in the control device to achieve the required flow rate and temperature, the device in the current state can be cooled and dissipated better and more appropriately, so that the device can operate more stably. At the same time, when the specified flow rate and temperature are reached, the device temperature is detected again, and compared with the detected temperature threshold at the same time, so that in this way it is possible to quickly determine whether the heat dissipation of the device is effective, and at the same time give an early warning for ineffective situations, so that the temperature monitoring of the device is more accurate and real-time, thereby ensuring the heat dissipation effectiveness and operation stability of the equipment.

[0010] In one example of the present invention, determining whether a temperature warning is needed based on the comparison result also includes: if the second temperature is greater than or equal to the detection temperature threshold, starting the fan cooling module and recording the second temperature and sending it to the operator's mobile terminal to issue a warning; if the second temperature is lower than the detection temperature threshold, recording the second temperature and sending it to the operator's mobile terminal.

[0011] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: by setting the fan to start cooling when the second temperature is greater than or equal to the detection temperature threshold, and sending information to the operator's mobile terminal, it means that the device is not cooled normally at this temperature and the temperature is still too high, so human intervention is required to cool the device and check the cause. At the same time, heat is dissipated through external cooling to avoid overheating of the device and thus causing overload. At the same time, the operator can be notified of the abnormality of the device in time, so that timely maintenance can be carried out, thereby improving the safety of equipment use.

[0012] In one example of the present invention, if the corresponding values ​​of the first temperature and the first reference value are not found, searching for similar temperature values ​​and similar reference values ​​in the historical database according to the first temperature and the first reference value respectively also includes: setting a first temperature similarity interval and a first reference similarity interval; according to the first temperature similarity interval, searching for similar temperature values ​​falling therein in the historical database; and searching for similar reference values ​​falling therein according to the first reference similarity interval.

[0013] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: by setting the first temperature similarity interval and the first reference similarity interval to correspond to finding two similar values ​​in the historical database, the situation represented by the current temperature can be determined more conveniently and quickly in this way. At the same time, this preliminary judgment can facilitate subsequent heat dissipation adjustments based on actual conditions, thereby improving the convenience and intelligence of judgment.

[0014] In one example of the present invention, searching for similar temperature values ​​falling into the first temperature similarity interval in a historical database and searching for similar reference values ​​falling into the first reference similarity interval further include: if there are multiple similar temperature values ​​or multiple similar reference values, determining whether they are respectively less than or greater than the first temperature and the first reference value; if so, taking the average values ​​of the multiple similar temperature values ​​and the multiple similar reference values ​​respectively; if not, taking multiple similar temperature values ​​greater than the first temperature and multiple similar reference values ​​greater than the first reference value, and taking the average values ​​of each.

[0015] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: by setting the situation where there are multiple similar temperature values ​​or multiple similar reference values ​​to determine whether they are all less than or greater than the first temperature and the first reference value, and taking their respective average values ​​when they are, so that the obtained similarity values ​​are more reasonable and more in line with the actual situation. At the same time, by setting the situation where they are not, taking the value greater than the side and taking the average value, the heat dissipation capacity is improved as much as possible while ensuring stability, making the operation of the equipment more stable, and ensuring the operating stability of the equipment and the degree of intelligence of the heat dissipation adjustment.

[0016] In one example of the present invention, performing a second heat dissipation adjustment on the device based on similar temperature values ​​and similar reference values ​​in combination with a historical database also includes: when there is a situation where the similar temperature value is greater than the first temperature, or there is a situation where the similar reference value is greater than the first reference value, or when both of the above situations exist, starting the fan heat dissipation module, and recording the first temperature and the first reference value and sending them to the operator's mobile terminal to issue an early warning.

[0017] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: by setting a situation where either a similar temperature value or a similar reference value is greater than the first temperature or the first reference value, the fan module is started and an early warning is issued. In this case, it indicates that the temperature in the cabinet is abnormal, that is, the current heat dissipation energy is insufficient to meet the cooling requirements of the equipment, and human intervention is required. This method improves the response capability to abnormalities in the cabinet, thereby making the temperature control of the equipment in the cabinet more intelligent.

[0018] The present invention also provides a heat dissipation device based on a rack-mounted cooling distribution unit, the heat dissipation device is used to implement any of the heat dissipation methods described above, the heat dissipation device includes: a shell, the shell is provided with a first accommodating cavity; a plurality of placement plates, the plurality of placement plates are arranged in the first accommodating cavity, and the plurality of placement plates are used to place electronic equipment; a first heat dissipation component, the first heat dissipation component is arranged in the first accommodating cavity, and the first heat dissipation component is connected to the electronic equipment; a second heat dissipation component, the second heat dissipation component is arranged in the shell.

[0019] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: by arranging multiple placement plates in the shell to place electronic devices, each electronic device will not be piled up and interfere with each other, and the heat dissipation effect of each device is better. At the same time, by arranging two heat dissipation devices to dissipate heat for the electronic equipment, the temperature control of the electronic equipment in the shell is more effective, avoiding the situation where a single heat dissipation device cannot guarantee the heat dissipation needs of the device, and making the device safer and more stable when working.

[0020] In one embodiment of the present invention, the first heat dissipation component also includes: a group of heat dissipation elements, the group of heat dissipation elements are arranged relatively to each other, and each heat dissipation element is provided with multiple connection ports; the connection ports are used to transport refrigerant to the electronic device; and a cooling distribution unit, the cooling distribution unit is connected to a group of heat dissipation elements.

[0021] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: by setting a group of heat sinks relatively to each other and setting a plurality of connection ports to connect electronic devices, more connection methods are provided for electronic devices through the setting of a plurality of connection ports, and at the same time, the cooling requirements can be met when a plurality of electronic devices work together, thereby making the temperature of the device more stable and avoiding overload.

[0022] After adopting the technical solution of the present invention, the following technical effects can be achieved: (1) By setting the internal temperature of the device, the number of devices, and the number of devices turned on, it is easier to control the internal conditions of the device in the future, and at the same time, the temperature of the device can be better controlled, and better heat dissipation can be achieved. At the same time, by comparing and querying historical conditions, the heat dissipation adjustment can be made more quickly for the heat dissipation conditions that are the same as the historical conditions, so that the temperature inside the device can be better controlled, and the internal temperature of the device can be adjusted more intelligently to ensure the stability of the device operation. At the same time, by taking similar conditions as a reference when the same historical conditions are not obtained, different heat dissipation adjustments can be made, so that the adjustment of the internal conditions of the device is more accurate, and it can also adapt to different device conditions, ensuring the stable operation of the device under different conditions, avoiding the overload of the device due to excessive temperature, and thus affecting the safety of the device. While ensuring the safety of the equipment, the controllability and intelligence of the heat dissipation of the equipment are improved; (2) By setting the refrigerant flow rate and refrigerant temperature in the control device to achieve the required flow rate and temperature, the device in the current state can be cooled and dissipated better and more appropriately, so that the device can operate more stably. At the same time, when the specified flow rate and temperature are reached, the device temperature is detected again and compared with the detection temperature threshold. This method can quickly determine whether the heat dissipation of the device is effective, and issue an early warning for ineffective situations, making the temperature monitoring of the device more accurate and real-time, ensuring the effectiveness of the heat dissipation and the stability of the operation of the device; (3) By setting up multiple placement plates in the shell to place electronic devices, each electronic device will not be piled up and interfere with each other, and the heat dissipation effect of each device is better. At the same time, by setting up two heat dissipation devices to dissipate heat for the electronic equipment, the temperature control of the electronic equipment in the shell is more effective, avoiding the situation where a single heat dissipation device cannot guarantee the heat dissipation needs of the device, thereby making the device safer and more stable when working.

[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention are described clearly and completely. 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.

[0026] [First embodiment] See also Figure 1The present invention provides a heat dissipation method based on a rack-type cooling distribution unit, comprising: Step S100: acquiring daily parameters of the recording device and establishing a historical database according to the daily parameters; acquiring the temperature inside the current device to obtain a first temperature; acquiring the number of electronic devices currently loaded inside the device to obtain a first number, and acquiring the number of electronic devices turned on to obtain a second number; Step S200: Calculate a first reference value according to the first quantity and the second quantity; and query a history database accordingly according to the first temperature and the first reference value; Step S300: If the corresponding historical first temperature and historical first reference value are found, the refrigerant parameters under the corresponding situation are obtained to perform the first heat dissipation adjustment on the equipment; if the corresponding values ​​of the first temperature and the first reference value are not found, similar temperature values ​​and similar reference values ​​are searched in the historical database respectively according to the first temperature and the first reference value; based on the similar temperature values ​​and similar reference values, and in combination with the historical database, the second heat dissipation adjustment is performed on the equipment.

[0027] Specifically, in actual use, a temperature detection module is provided inside the cabinet to detect the temperature inside the cabinet in real time on a daily basis, and the data is recorded in real time and transmitted to the data processing module and the data terminal, and sorted in the data terminal. At the same time, the internal parameters of each cabinet are uploaded to the data terminal, that is, the number of electronic equipment in the device and the number of devices currently turned on in the cabinet. The number of electronic equipment turned on is changed manually or through the number of data accesses to reflect the number of devices currently turned on, and these data are integrated into a historical database. At the same time, the historical database also has the corresponding refrigerant parameters for each case, that is, the flow rate of the refrigerant and the temperature of the refrigerant, as well as the heat dissipation method and heat dissipation adjustment method in this case.

[0028] Specifically, in daily temperature detection, the temperature obtained is the first temperature, and the first reference value obtained by the ratio of the first quantity and the second quantity is combined to adjust the temperature of the current device for heat dissipation. Specifically, the first temperature is input into the historical database for query. If the corresponding temperature is queried, and the historical first reference value corresponding to the corresponding first reference value is queried at the same time, it means that the current situation can find the corresponding heat dissipation adjustment measures in the historical database, that is, how to control the parameters of the refrigerant through the cooling distribution unit and whether the cooling fan needs to be turned on.

[0029] Furthermore, if only the corresponding historical first temperature is queried but the corresponding historical first reference value is not queried, or only the corresponding historical first reference value is queried but the corresponding historical first temperature is not queried, the refrigerant parameters and heat dissipation adjustment measures corresponding to one of the queried ones are adjusted and stabilized, and the temperature is detected again after the first time. If the temperature does not drop, an early warning message is sent to the operator's mobile terminal, and the fan module is turned on for heat dissipation.

[0030] Furthermore, when no corresponding historical values ​​are found, the first temperature and the first reference value are substituted into the historical database, and the first temperature similarity interval and the first reference similarity interval that are set manually are used for querying to determine whether there are values ​​that fall into the two intervals, and adjustments are made according to the falling conditions. That is, it is divided into whether both are greater than or less than the first temperature and the first reference value, and whether there are cases where the values ​​fall on both sides of the interval. If the values ​​fall on both sides, the average value of the values ​​greater than one side is taken as the final similarity value.

[0031] Preferably, by setting up to obtain the internal temperature of the device and the number of devices and the number of devices that are turned on, it is possible to facilitate subsequent control of the internal situation of the device, and at the same time, the temperature of the device can be better controlled, and better heat dissipation can be achieved. At the same time, by comparing and querying historical situations, the heat dissipation adjustment can be made more quickly for the heat dissipation situation that is the same as the historical situation, so that the internal temperature of the device can be better controlled, and the internal temperature of the device can be adjusted more intelligently to ensure the stability of the operation of the device. At the same time, by taking similar situations as a reference when the same historical situation is not obtained, different heat dissipation adjustments can be made, so that the adjustment of the internal situation of the device is more accurate, and it can also adapt to different equipment conditions, ensuring the stable operation of the equipment under different conditions, avoiding excessive temperature of the equipment causing overload of the equipment, and then affecting the safety of the equipment, while ensuring the safety of the equipment, the controllability and intelligence of the heat dissipation of the equipment are improved.

[0032] Specifically, calculating the first reference value according to the first quantity and the second quantity includes: the first reference value is a ratio of the first quantity to the second quantity.

[0033] Preferably, by setting the first reference value as the ratio of the number of devices to the number of devices turned on, the equipment situation inside the entire cabinet can be more completely reflected, so that the subsequent temperature adjustment of the equipment inside the cabinet is more in line with the actual situation, and the stable adjustment inside the cabinet is more intelligent, avoiding the situation where the temperature is too high and the equipment is overloaded.

[0034] Specifically, if the corresponding historical first temperature and the historical first reference value are queried, obtaining the refrigerant parameters in the corresponding situation to perform the first heat dissipation adjustment on the equipment also includes: the refrigerant parameters include: the first refrigerant flow rate and the first refrigerant temperature; controlling the refrigerant flow rate in the current equipment to reach the first refrigerant flow rate, controlling the refrigerant temperature in the current equipment to reach the first refrigerant temperature, and then performing temperature detection on the equipment again after both are reached to obtain a second temperature; comparing the second temperature with the detection temperature threshold to obtain a comparison result, and judging whether a temperature warning is needed based on the comparison result.

[0035] Specifically, the detection temperature threshold is an artificially set value obtained through experiments and can be adjusted according to actual conditions.

[0036] Preferably, by setting the refrigerant flow rate and refrigerant temperature in the control device to achieve the required flow rate and temperature, the device in the current state can be cooled and dissipated better and more appropriately, so that the device can operate more stably. At the same time, when the specified flow rate and temperature are reached, the temperature of the device is detected again, and compared with the detected temperature threshold. In this way, it is possible to quickly determine whether the heat dissipation of the device is effective, and issue a warning for ineffective situations, thereby making the temperature monitoring of the device more accurate and real-time, thereby ensuring the effectiveness of the heat dissipation of the equipment and the stability of its operation.

[0037] Specifically, judging whether a temperature warning is needed based on the comparison result also includes: if the second temperature is greater than or equal to the detection temperature threshold, starting the fan cooling module and recording the second temperature, and sending it to the operator's mobile terminal to issue a warning; if the second temperature is lower than the detection temperature threshold, recording the second temperature and sending it to the operator's mobile terminal.

[0038] Preferably, by setting the fan to start cooling when the second temperature is greater than or equal to the detection temperature threshold, and sending information to the operator's mobile terminal, it means that the device is not cooled normally at this temperature and the temperature is still too high, so human intervention is required to cool the device and check the cause. At the same time, heat is dissipated through external cooling to avoid the device's temperature being too high and causing overload. At the same time, the operator can be notified of the abnormality of the device in time, so that timely maintenance can be carried out, thereby improving the safety of equipment use.

[0039] Specifically, if the corresponding values ​​of the first temperature and the first reference value are not found, searching for similar temperature values ​​and similar reference values ​​in the historical database according to the first temperature and the first reference value respectively also includes: setting a first temperature similarity interval and a first reference similarity interval; according to the first temperature similarity interval, searching for similar temperature values ​​falling therein in the historical database; and searching for similar reference values ​​falling therein according to the first reference similarity interval.

[0040] Specifically, the first temperature similarity interval and the first reference similarity interval are manually set intervals, which can be adjusted and set according to the properties of the equipment actually used. For example, the range of the first temperature similarity interval can be plus or minus two degrees Celsius above or below the first temperature, and the range of the first reference similarity interval can be plus or minus one tenth above or below the first reference value.

[0041] Preferably, by setting the first temperature similarity interval and the first reference similarity interval to correspond to searching for two similar values ​​in the historical database, it is possible to more conveniently and quickly determine the situation represented by the current temperature. At the same time, this preliminary judgment can facilitate subsequent heat dissipation adjustments based on actual conditions, thereby improving the convenience and intelligence of judgment.

[0042] Specifically, searching for similar temperature values ​​falling into the first temperature similarity interval in the historical database and searching for similar reference values ​​falling into the first reference similarity interval also include: if there are multiple similar temperature values ​​or multiple similar reference values, determining whether they are respectively less than or greater than the first temperature and the first reference value; if so, taking the average values ​​of the multiple similar temperature values ​​and the multiple similar reference values ​​respectively; if not, taking multiple similar temperature values ​​greater than the first temperature and multiple similar reference values ​​greater than the first reference value, and taking the average values ​​of each.

[0043] Preferably, by setting the situation where there are multiple similar temperature values ​​or multiple similar reference values ​​to determine whether they are all less than or greater than the first temperature and the first reference value, and taking their respective average values ​​when they are, the obtained similarity value is made more reasonable and more in line with the actual situation. At the same time, by setting the situation where it is not the case, taking the value greater than the side and taking the average value, the heat dissipation capacity is improved as much as possible while ensuring stability, making the operation of the equipment more stable, and ensuring the operating stability of the equipment and the degree of intelligence of the heat dissipation adjustment.

[0044] Specifically, performing a second heat dissipation adjustment on the equipment based on similar temperature values ​​and similar reference values ​​and in combination with a historical database also includes: when a similar temperature value is greater than the first temperature, or a similar reference value is greater than the first reference value, or both of the above situations exist, starting the fan heat dissipation module, and recording the first temperature and the first reference value and sending them to the operator's mobile terminal to issue an early warning.

[0045] Specifically, a historical database is queried based on the acquired first temperature and first reference value, and with the help of the first temperature similarity interval and the first reference similarity interval, corresponding similar temperature values ​​and similar reference values ​​are obtained and compared with the first temperature and the first reference value. If either the similar temperature value is greater than the first temperature, or the similar reference value is greater than the first reference value, the fan is started to dissipate heat and data is sent to the mobile terminal. Specifically, the case where the temperature is greater than the first temperature requires ensuring that the current device temperature will not be higher than the similar temperature value or the similar reference value, which can better ensure that the temperature tends to be standardized, so that the device changes to the control state corresponding to the similar temperature value or the similar reference value, thereby ensuring stable operation of the device.

[0046] Preferably, by setting a situation where one of the similar temperature value and the similar reference value is greater than the first temperature or the first reference value, the fan module is started and an early warning is issued. In this case, it indicates that the temperature in the cabinet is abnormal, that is, the current heat dissipation energy is insufficient to meet the cooling requirement of the equipment, and human intervention is required. This method improves the response capability to abnormalities in the cabinet, thereby making the temperature control of the equipment in the cabinet more intelligent.

[0048] Specifically, the second heat dissipation component may be a fan, and the fan is disposed on the top of the housing 110 .

[0049] Preferably, multiple placement plates 120 are provided in the shell 110 to place electronic devices, so that each electronic device will not be piled up and interfere with each other, and the heat dissipation effect of each device is better. At the same time, two heat dissipation devices are provided to dissipate heat for the electronic devices, so that the temperature control of the electronic devices in the shell 110 is more effective, avoiding the situation where a single heat dissipation device cannot guarantee the heat dissipation needs of the device, and making the device safer and more stable when working.
