Description
Technical Field
The invention relates to the technical field of thermal management, in particular to a thermal management method, a system, equipment and a medium of a high-integration airtight electronic cabinet.
Background
In the field of modern electronic equipment, a high-integration airtight electronic cabinet is widely applied to scenes such as a data center, a communication base station, industrial automation and the like. These cabinets typically contain multiple tiers of cabinets, each of which houses a large number of different types of electronic equipment, such as servers, switches, routers, etc. These devices generate a large amount of heat during operation, and effective heat dissipation measures are required to ensure proper operation.
Traditional heat dissipation scheme:
Currently, a high-integration airtight electronic cabinet generally adopts a gas-liquid heat exchanger to provide cold air for heat dissipation. Each layer of plug-in boxes in the cabinet is provided with a large number of different air-cooled plug-ins according to the use requirement, and the heat productivity of the plug-ins is obviously different.
In order to meet the heat dissipation requirement, each plug box is usually provided with fans of different types and specifications, and the air quantity and the rotating speed of the fans are required to be specially designed according to the actual heat productivity in the plug box.
The problems are that:
The customization requirement is high, and because the heating values of the plug boxes are different, a special design and type selection fan is required for each layer of plug boxes, so that the universality of the cabinet is reduced. Cabinet manufacturers need to customize designs for different application scenarios and equipment configurations, increasing design costs and time.
Power consumption and noise problems in order to ensure the heat dissipation effect, a part of the plug-in boxes may need to be provided with a high air volume fan. However, high volume fans are typically accompanied by high power consumption and high noise. In practical applications, a portion of the plug-in boxes may not require such high air volume, resulting in power consumption and noise waste.
The heat management is complex, the number of electronic devices in the cabinet is large, the number of heat dissipation fans is also large, and the electronic devices in the cabinet need to be subjected to fine heat management. Traditional thermal management mode mainly relies on fixed fan configuration and preset heat dissipation strategy, is difficult to carry out dynamic adjustment according to actual operation condition, and results in unsatisfactory heat dissipation effect.
The lack of intelligent regulation is that in the prior art, the rotational speed of the fan is usually fixed or can only be adjusted simply manually. The fixed heat dissipation strategy cannot dynamically adjust the rotating speed of the fan according to the actual heat productivity of the plug-in box, so that the heat dissipation effect is poor or the power consumption is too high.
The universality is not enough, because the difference of the heating values of the plug boxes is large, a fan is required to be specially designed for each layer of plug boxes, and the universality of the cabinet is reduced. Cabinet manufacturers need to customize designs for different application scenarios and equipment configurations, increasing design costs and time.
The power consumption and noise optimization are insufficient, and the high-air-volume fan can provide enough heat dissipation, but also brings the problems of high power consumption and high noise. In practical applications, a portion of the plug-in boxes may not require such high air volume, resulting in power consumption and noise waste.
Disclosure of Invention
The invention aims to solve the technical problems of the prior art, and particularly provides a heat management method, a system, equipment and a medium for a high-integration airtight electronic cabinet, which are as follows:
1) In a first aspect, the present invention provides a thermal management method for a high-integration airtight electronic cabinet, which specifically adopts the following technical scheme:

and acquiring the final temperature difference information of each plug box, and carrying out third adjustment on the fan rotating speed of the plug box corresponding to the final temperature difference information meeting the third preset condition according to the preset third temperature difference threshold value.
The heat management method of the high-integration airtight electronic cabinet has the following beneficial effects:
The temperature difference information is obtained in stages, and the rotating speed of the fan is dynamically adjusted according to the preset threshold value, so that the precise control of the temperature of each plug box in the high-integration sealed electronic cabinet is realized. Firstly, the rotating speed of the fan can be flexibly adjusted according to the actual heating value of each plug box, and the problem of insufficient heat dissipation or excessive heat dissipation caused by the configuration of the fixed fan is avoided, so that the heat dissipation efficiency and the reliability of the cabinet are obviously improved. Secondly, the scheme reduces the requirement on the customized fan, reduces the design and manufacturing cost of the cabinet, and improves the universality and usability of the cabinet, so that the cabinet can be better adapted to different application scenes and equipment configurations. In addition, through optimizing the fan rotational speed, under the prerequisite of guaranteeing the radiating effect, effectively reduced the holistic consumption of rack and noise level, realized energy-conserving noise reduction's target, provided powerful guarantee for the long-term steady operation of rack, also provided support for the high-efficient operation and maintenance of large-scale electronic equipment such as data center.
On the basis of the scheme, the invention can be improved as follows.
Further, the process of performing the first adjustment on the fan rotation speed of the plug-in box corresponding to the initial temperature difference information meeting the first preset condition specifically includes:
All initial temperature difference information is distributed in a descending order to generate a first initial temperature difference sequence;
judging whether first initial temperature difference information in a first initial temperature difference sequence is larger than a first temperature difference threshold value or not, and generating a first judgment result;
When the first judgment result is yes, switching the fan rotating speed of the plug box corresponding to the first initial temperature difference information to full speed, and simultaneously recalculating the initial temperature difference information to obtain new initial temperature difference information;

And when the second judgment result is yes, reducing the fan rotating speed of the plug box corresponding to the last new initial temperature difference information.
The beneficial effects of the above-mentioned further scheme are:
Through the fine fan rotating speed adjustment strategy, the precise optimization of the heat dissipation state of each plug box in the high-integration airtight electronic cabinet is realized. Specifically, firstly, the initial temperature difference information is arranged in descending order, whether the maximum temperature difference exceeds a threshold value is judged, the most urgent plug box with heat dissipation requirements can be rapidly identified, and the rotating speed of a fan of the plug box is switched to full speed, so that the heat dissipation condition of the plug box is rapidly improved, and the performance degradation or the failure of equipment caused by local overheating is avoided. Then, the temperature difference is recalculated and arranged in descending order again, whether the minimum temperature difference is lower than a threshold value is further judged, if the minimum temperature difference is lower than the threshold value, the rotating speed of the fan corresponding to the plug box is reduced, the process not only ensures the instantaneity and the effectiveness of the heat dissipation effect, but also achieves the aims of energy conservation and noise reduction, and unnecessary power consumption and noise caused by excessive operation of the fan are avoided. The dynamic and hierarchical adjustment mode ensures that heat dissipation resources in the cabinet can be reasonably distributed according to the actual requirements of each plug box, so that the heat dissipation efficiency and reliability of the cabinet are further improved, the overall power consumption and noise level are reduced, and the stability and economical efficiency of the system are enhanced.
Further, the process of performing the second adjustment on the fan rotation speed of the plug-in box corresponding to the intermediate temperature difference information meeting the second preset condition specifically includes:
all the intermediate temperature difference information is distributed in a descending order to generate an intermediate temperature difference sequence;
Judging whether the last intermediate temperature difference information in the intermediate temperature difference sequence is smaller than a second temperature difference threshold value, and generating a third judgment result;
and when the third judgment result is yes, reducing the fan rotating speed of the plug box corresponding to the last intermediate temperature difference information.
The beneficial effects of the above-mentioned further scheme are:
The heat dissipation performance and the energy consumption balance of each plug box in the high-integration airtight electronic cabinet are further optimized through a targeted fan rotating speed adjustment strategy. Specifically, through descending order arrangement to the intermediate temperature difference information and judging whether minimum temperature difference is lower than a second temperature difference threshold value, the relatively low-heat-dissipation-requirement plug boxes can be accurately identified, and the fan rotating speed of the plug boxes is reduced accordingly. The adjustment not only avoids the waste of power consumption and the increase of noise caused by the overhigh rotating speed of the fan, but also ensures that the temperature of each plug box in the cabinet is maintained in a reasonable range, thereby obviously improving the energy-saving effect and the operation stability of the system while ensuring the heat dissipation effect. In addition, the dynamic adjustment mechanism based on the real-time monitoring data enhances the intelligent level of the cabinet heat dissipation system, so that the cabinet heat dissipation system can better adapt to heat dissipation demand changes of different plug-ins in different operation stages, the service life of equipment is further prolonged, and the operation and maintenance cost is reduced.
Further, the process of performing the third adjustment on the fan rotation speed of the plug-in box corresponding to the final temperature difference information meeting the third preset condition specifically includes:
all final temperature difference information is distributed according to a descending order to generate a final temperature difference sequence;
sequentially calculating a target difference value between each piece of final temperature difference information in the final temperature difference sequence and a third temperature difference threshold value;
judging whether all target difference values are smaller than a preset temperature difference range value or not, and generating a fourth judgment result;
And when the fourth judgment result is yes, keeping the current fan rotating speeds of all the plug boxes;
And when the fourth judging result is negative, reducing the fan rotating speeds of all the plug boxes and reducing the fan rotating speed of the heat exchanger.
The beneficial effects of the above-mentioned further scheme are:
Through a refined global adjustment strategy, the overall optimization of the heat dissipation state of each plug box and each heat exchanger in the high-integration airtight electronic cabinet is realized. Specifically, by arranging the final temperature difference information in a descending order and sequentially calculating the target difference value between each temperature difference and the third temperature difference threshold value, whether the heat dissipation state of each plug box in the cabinet reaches ideal balance can be comprehensively estimated. When any target difference value exceeds the preset range, the fan speeds of all the plug boxes and the heat exchangers are synchronously reduced, so that the overall heat dissipation efficiency is optimized and adjusted, and the power consumption waste, the noise increase and the equipment operation risk caused by excessive or insufficient local heat dissipation are avoided. The dynamic adjustment mechanism based on global evaluation further improves the intelligent level and the overall performance of the cabinet heat dissipation system, ensures that each device in the cabinet stably operates in an efficient, energy-saving and low-noise environment, enhances the reliability and the adaptability of the system, and provides powerful guarantee for long-term stable operation of the high-integration airtight electronic cabinet.
