Description

Technical Field

[0001] This application relates to the field of communication equipment control technology, specifically to a heat dissipation structure and control method for communication equipment using a combination of air and liquid cooling. Background Technology

[0002] Liquid cooling technology is highly favored for its unique advantages. Compared with air cooling, liquid cooling has obvious advantages. Liquid droplet-shaped coolant has a large surface area and a large contact area with heat dissipation pipes and surrounding air, which can more effectively exchange heat. In addition, droplet-shaped coolant can more flexibly adapt to the complex spatial structure and hardware layout within the device, improving the effectiveness and targeting of heat dissipation. Therefore, this application proposes a heat dissipation structure and control method that integrates air and liquid cooling for communication equipment.

[0003] Existing technology, such as the invention patent application with publication number CN118678135B, discloses a heat exchange method and system for communication equipment based on a fusion of air-cooling and liquid-cooling. It includes: when the outdoor temperature is greater than or equal to a first ambient temperature threshold, the air-liquid cooling module transfers heat from the communication equipment cabinet to the interface with the heat conduction module, and the heat conduction module enters a hot air emission mode; when the outdoor temperature is less than the first ambient temperature threshold, the heat conduction module enters an airflow circulation mode, simultaneously emitting hot air and introducing a cold source; when the outdoor temperature is less than a second ambient temperature threshold, the heat conduction module enters a cold source introduction mode; and the heat exchange rate is adjusted according to the difference between the indoor temperature at the heat conduction module and the corresponding ambient temperature threshold. This invention introduces an air-liquid cooling module and a heat conduction module to achieve efficient heat transfer from the communication equipment, possessing dynamic energy-saving advantages; it also introduces a natural cold source to achieve terminal cooling, providing a suitable operating temperature for the communication equipment while exhibiting significant energy-saving advantages.

[0004] The above solution has the following technical problems: 1. The current technology mainly compares the outdoor temperature with various temperature thresholds and then adjusts the system to enter different working modes to conduct heat from the communication equipment. The current technology relies too much on the outdoor ambient temperature to switch the heat dissipation mode. When the outdoor ambient temperature fluctuates frequently, the system may frequently switch working modes, which may lead to the inability to guarantee the stability of the system. At the same time, it cannot meet the heat dissipation requirements of the communication equipment in extremely cold or hot conditions.

[0005] 2. Current technology does not take into account the use of droplet coolant in conjunction with an air-cooling system to achieve efficient heat dissipation of communication equipment. Compared with natural cooling sources, droplet coolant can adjust droplet parameters according to the real-time heat generation of the equipment, thereby precisely controlling the heat dissipation effect, and is not affected by ambient temperature. The current technology's neglect of this aspect may lead to the equipment's heat dissipation failing to achieve the expected results. Summary of the Invention

[0006] The purpose of this application is to provide a heat dissipation structure and control method for communication equipment that integrates air and liquid cooling, thereby solving the problems existing in the background art.

[0007] To solve the above technical problems, this application adopts the following technical solution: This application provides a heat dissipation structure and control method for air-liquid fusion in communication equipment, including: Step 1, pipe installation: obtain the operating temperature of each hardware structure inside the core switch, thereby obtaining each hardware structure that needs air-liquid fusion heat dissipation, and obtaining the location information of each hardware structure that needs air-liquid fusion heat dissipation, thereby analyzing and obtaining the installation path of the liquid cooling pipe inside the core switch.

[0008] Step 2, Air-Liquid Fusion Heat Dissipation Control: The heat dissipation intensity of the air-liquid fusion system is analyzed through experiments to obtain the optimal adjustment parameters of the air-cooling system and the liquid-cooling system under different loads, and the liquid-cooling system and the air-cooling system are controlled to work together to achieve the preset heat dissipation effect.

[0009] Step 3: Fault monitoring: Determine whether a fault has occurred during the heat dissipation process of the core switch, analyze the cause of the fault, and then resolve the fault in a targeted manner.

[0010] The beneficial effects of this application are as follows: 1. The heat dissipation structure and control method of air-liquid fusion for communication equipment provided by this application analyzes the working temperature of each hardware structure inside the core switch, thereby obtaining the hardware structure that needs air-liquid fusion heat dissipation, thus determining the installation path of the liquid cooling pipe inside the core switch, and then analyzes the optimal adjustment parameters of the air-liquid fusion system under various loads through experiments, and controls the heat dissipation of the air-liquid fusion system based on the optimal adjustment parameters of the air-liquid fusion system. The method of obtaining the optimal parameter set through experiments can be customized for different devices, so that the air-liquid fusion system can flexibly adapt to the heat dissipation requirements of various core switches, thereby improving the versatility and applicability of the system.

[0011] 2. This application analyzes the operating temperature of each hardware structure inside the core switch to obtain the installation path of the liquid cooling pipes inside the core switch. Based on this, heat dissipation resources can be concentrated on hardware structures that generate a lot of heat and are sensitive to temperature, which can also reduce interference with other hardware structures. At the same time, it shortens the flow path of the coolant, improves the overall efficiency of the heat dissipation system, and lays the foundation for the heat dissipation work of the subsequent air-liquid fusion system.

[0012] 3. This application obtains the optimal parameter set of the air-liquid fusion system under various loads through experimental analysis, and controls the air-liquid fusion system of the core switch under various loads based on the optimal parameter set, thereby ensuring that the core switch is always at a suitable operating temperature. Compared with the traditional fixed parameter cooling system, the air-liquid fusion system that dynamically adjusts according to the actual load significantly reduces the overall energy consumption of the system while ensuring the cooling effect. Through precise control, unnecessary energy consumption is avoided, which helps data centers and other places achieve energy conservation and emission reduction goals, reduce operating costs, and the automatic control based on the optimal parameter set reduces the need for manual intervention. The system can automatically optimize the operating status according to the load of the core switch, making the cooling work simpler and more efficient. Different models and specifications of core switches may have differences in performance and cooling requirements. The method of obtaining the optimal parameter set through experiments can be customized for different devices, so that the air-liquid fusion system can flexibly adapt to the cooling requirements of various core switches, improving the versatility and applicability of the system.

[0013] 4. This application uses droplet-type coolant instead of traditional fluid coolant to complete the heat dissipation of the liquid cooling system. Compared with traditional coolant, droplet-type coolant has a larger contact area with air. Compared with air heat dissipation, liquid heat dissipation has obvious advantages: the thermal conductivity of liquid is 25 times that of air. Under the same heat dissipation level, the noise of the liquid cooling system is 10-15 dB lower than that of the air cooling system, and the liquid cooling system saves 30% more energy than the air cooling system. It effectively solves the problems of high-density heat dissipation and uneven heat dissipation that ordinary heat dissipation systems cannot achieve. It has a higher specific heat capacity and heat transfer coefficient, and the heat dissipation power can be adjusted by adjusting the diameter and density of the droplets. Since droplet-type coolant does not need to maintain continuous flow in the pipes like traditional fluid coolant, the pumping power required during transportation is lower. This means that a smaller pump can be used to drive the coolant circulation, thereby reducing the energy consumption of the heat dissipation system and reducing energy consumption and operating costs. At the same time, droplet-type coolant can be precisely delivered to specific locations in the pipes through special nozzles or distribution devices to achieve targeted heat dissipation, which makes the layout of the heat dissipation system more flexible.

[0014] 5. This application monitors the temperature of the hardware structure during the heat dissipation of the core switch, thereby promptly identifying heat dissipation faults and addressing them in a targeted manner. This helps ensure the stable performance of the equipment and also guarantees the stability and integrity of the system. Attached Figure Description

Obviously, the drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0016] Figure 1 This is a flowchart illustrating the steps involved in implementing the method described in this application. Detailed Implementation

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] Reference Figure 1 As shown, this application provides a heat dissipation structure and control method for air-liquid fusion in communication equipment, including the following steps: Step 1, pipe installation: obtain the operating temperature of each hardware structure inside the core switch, thereby obtaining each hardware structure that needs air-liquid fusion heat dissipation, and obtain the location information of each hardware structure that needs air-liquid fusion heat dissipation, thereby analyzing and obtaining the installation path of the liquid cooling pipe inside the core switch.

[0019] In a specific example, the process of obtaining the operating temperature of each hardware structure inside the core switch, and then obtaining the hardware structure that needs air-liquid fusion heat dissipation, is as follows: S1, the administrator connects to the core switch through a serial port or network, and uses a query command to query the temperature of each hardware structure in the core switch, and obtains the temperature of each hardware structure at each query time point according to this method.

[0020] It should be noted that the query command is set by the manufacturer when the core switch leaves the factory. For example, on a Cisco switch, you can use "show environment" to view the device's environmental parameters, including the temperature of each hardware component.

[0021] It should be noted that the number of query time points and the specific time are set by the relevant management personnel and no specific restrictions are imposed here.

[0022] S2. When the operating temperature of a certain hardware component is greater than or equal to 45℃ at a certain query time point, the hardware component is recorded as a hardware structure that requires air-liquid fusion heat dissipation; otherwise, the hardware structure is recorded as a hardware structure that does not require air-liquid fusion heat dissipation. Based on this, the hardware structures that require air-liquid fusion heat dissipation and the hardware structures that do not require air-liquid fusion heat dissipation of the core switch are obtained.

[0023] In a specific example, the process of obtaining the location information of each hardware structure requiring integrated air-liquid cooling to analyze and determine the installation path of the liquid cooling pipes inside the core switch is as follows: Any hardware structure inside the core switch requiring integrated air-liquid cooling is identified and designated as the first target cooling hardware. The temperatures of each hardware structure adjacent to the first target cooling hardware at each query time point are obtained. The hardware structure with the highest temperature is designated as the second target cooling hardware. A liquid cooling pipe is installed between the first and second target cooling hardware. Based on this, the installation of each liquid cooling pipe inside the core switch is determined. A heat exchanger is installed outside the core switch, connecting the liquid cooling pipes inside the core switch to the heat exchanger outside the core switch.

[0024] Step 2, Air-Liquid Fusion Heat Dissipation Control: The heat dissipation intensity of the air-liquid fusion system is analyzed through experiments to obtain the optimal adjustment parameters of the air-cooling system and the liquid-cooling system under different loads, and the liquid-cooling system and the air-cooling system are controlled to work together to achieve the preset heat dissipation effect.

[0025] In one specific example, the air-liquid fusion system includes an air-cooling system and a liquid-cooling system.

[0026] In a specific example, the heat dissipation intensity of the air-liquid fusion system is analyzed through experiments to obtain the optimal adjustment parameters of the air-cooled and liquid-cooled systems under different loads. The specific process is as follows: By conducting liquid cooling tests on the core switch, the diameter, density, and contact area between the droplets and the liquid cooling pipes of multiple sets of liquid droplets under various loads are obtained. The liquid cooling efficiency function under each load is output through the liquid cooling model. Similarly, air cooling tests are conducted on the core switch to obtain the wind speed of multiple sets of adjustable-speed electric fans under various loads. The air cooling efficiency function under each load is output through the air cooling model expression.

[0027] It should be noted that after setting the laboratory environment to a constant state, the core switch was started, and three experimental control groups were set up with loads of 200W, 400W, and 700W respectively. Simultaneously, under constraints, the coolant in the liquid cooling pipes was set to be in droplet form for liquid cooling of the core switch, and an adjustable-speed fan was set up outside the liquid cooling pipes for air cooling of the core switch. Once the setup was complete and all devices were properly connected, the experiment began. During the experiment, the diameter, density, and contact area between the droplets and the liquid cooling pipes were adjusted, and the droplet diameter, density, and contact area were recorded as follows: , , ,in These are the numbers for each experimental control group. Numbers 1, 2, and 3 represent the experimental control group numbers for loads of 200W, 500W, and 700W, respectively. Under each load condition, the diameter, density, and contact area between the droplets and the liquid cooling pipe are measured. Multiple sets of droplet diameters, densities, and contact areas under each load are then obtained and substituted into the liquid cooling system heat dissipation model to output the... Liquid cooling efficiency function of each experimental group ,in Pi This is represented as the set latent heat of vaporization. and Represented as the first The load and continuous working time of each experimental group For evaporation efficiency, ,in The vapor concentration at the droplet surface. The concentration of mainstream vapor in the air, This represents the rate of change of evaporation efficiency over time.

[0028] It should be noted that the constant laboratory environment includes constant temperature and constant humidity, for example, setting the laboratory temperature to 25°C and the humidity to 30%.

[0029] It should be noted that the constraints are set by the relevant personnel themselves, such as setting the speed of the adjustable electric fan to 1-5 m / s, or setting the droplet diameter to 5 micrometers to 5 millimeters, etc., and no specific restrictions are imposed here.

[0030] It should be noted that, compared to traditional coolants, droplet coolants have higher specific heat capacity and thermal conductivity, enabling them to absorb and transfer heat more effectively.

[0031] It should be noted that by adjusting the jet pressure of the droplets, the contact area between the droplets and the heat dissipation pipes can be changed.

[0032] It should be noted that the vapor concentration on the droplet surface is directly measured using a static vapor pressure meter.

[0033] It should be noted that the mainstream air vapor concentration at the current temperature can be obtained directly from the air vapor concentration table.

[0034] It should be noted that during the experiment, the wind speed of the adjustable-speed electric fan in the air-cooling system was recorded as... The fan speed of the adjustable-speed electric fan in the air-cooling system is measured under various load conditions to obtain the fan speed of multiple adjustable-speed electric fans under each load. This data is then substituted into the air-cooling system heat dissipation model to output the first... Air-cooled heat dissipation efficiency function for each experimental group: ,in and These represent the surface temperature of the core switch hardware components and the internal air temperature of the core switch, respectively. This is an empirical coefficient. This is the speed index.

[0035] It should be noted that in related research, researchers have conducted extensive experimental studies, theoretical analyses and data fitting on many common fluid and heat transfer conditions, and determined the empirical coefficient to be 18.3 and the velocity exponent to be 0.6.

[0036] The air-cooled heat dissipation function and liquid-cooled heat dissipation function under each load are solved using a genetic algorithm or a particle swarm optimization algorithm, thereby obtaining the optimal adjustment parameters of the air-cooled system and liquid-cooled system under different loads, which are denoted as the optimal parameter set for each load.

[0037] It should be noted that the genetic algorithm or particle swarm optimization algorithm mentioned are existing technologies. For example, under a certain load, the parameters in the liquid cooling efficiency function and the air cooling efficiency function—such as the droplet diameter, density, contact area between the droplet and the liquid cooling pipe, and the speed of the adjustable fan—are converted into binary strings with a preset precision. Then, the binary strings of each parameter are combined into a parameter set, and then any number of parameter sets are randomly generated to form the initial parameter set. Each set contains a set of parameter values, and the function is defined as follows: The fitness of each set of parameters was analyzed. Multiple parameter sets are randomly selected from the initial parameter set for fitness calculation. The parameter sets with the highest fitness in each set are then subjected to crossover and mutation operations to generate new parameter sets. Fitness calculation is performed on each new parameter set. The above steps are repeated until the fitness no longer increases. At this point, the parameter set corresponding to the highest fitness is recorded as the optimal parameter set for that load. The optimal parameter set for each load is obtained accordingly.

[0038] It should be noted that the optimal parameter set includes parameters for the liquid cooling system and parameters for the air cooling system. The parameters for the liquid cooling system include the diameter and density of the liquid droplets in the liquid cooling pipes, the contact area between the droplets and the liquid cooling pipes, etc., while the parameters for the air cooling system include the wind speed and wind force of the adjustable-speed electric fan, etc.

[0039] It should be noted that the crossover operation means randomly selecting a positional parameter from two sets and swapping the parameters before or after that parameter; the mutation operation means randomly changing the value of a parameter in a set.

[0040] In a specific example, the control liquid cooling system and the air cooling system work together to achieve a preset heat dissipation effect. The specific process is as follows: When the core switch is working, it obtains the real-time load of the core switch from the data center and transmits the real-time load to the judgment module. The judgment module compares the real-time load with the set load thresholds for each level. When the load of the core switch is less than the set low load, the judgment module sends control signal 1 to the control module. When the load of the core switch is higher than the low load but lower than the medium load, the judgment module sends control signal 2 to the control module. When the load of the core switch is higher than the medium load but lower than the high load, the judgment module sends control signal 3 to the control module. When the real-time load of the core switch is higher than the high load, the judgment module sends control signal 4 to the control module. After receiving the signals from the judgment module, the control module performs corresponding control operations on the air-liquid fusion system.

[0041] It should be noted that the low load is 200W, the medium load is 400W, and the high load is 700W.

[0042] In a specific example, after receiving a signal from the judgment module, the control module performs corresponding control operations on the air-liquid fusion system. The specific process is as follows: After receiving control signal 1 from the judgment module, the control module controls the air-liquid fusion system to not need to cool the core switch; when the control module receives control signal 2 from the judgment module, it obtains the optimal cooling parameter set for low load from the data center, and then adjusts the adjustable speed fan of the air-cooling system and the droplet parameters of the liquid-cooling system according to the optimal parameters for low load, thereby cooling the core switch; when the control module receives control signal 3 from the judgment module, it obtains the optimal cooling parameter set for medium load from the data center, and then adjusts the adjustable speed fan of the air-cooling system and the droplet parameters of the liquid-cooling system according to the optimal cooling parameters for medium load; when the control module receives control signal 4 from the judgment module, it obtains the optimal cooling parameter set for high load from the data center, and then adjusts the adjustable speed fan parameters of the air-cooling system and the droplet parameters of the liquid-cooling system according to the high-load cooling parameters, thus completing the corresponding control operations on the air-liquid fusion system according to the above method.

[0043] Step 3: Fault monitoring: Determine whether a fault has occurred during the heat dissipation process of the core switch, analyze the cause of the fault, and then resolve the fault in a targeted manner.

[0044] In a specific example, the process of determining whether a fault has occurred during the heat dissipation of the core switch is as follows: When the core switch is in a heat dissipation state, the temperature of each hardware structure of the core switch is compared with the set temperature threshold of each hardware structure. If the temperature of a hardware structure of the core switch is lower than or equal to the set operating temperature threshold of that hardware structure, it is determined that the hardware component of the core switch has not failed. If the temperature of a hardware structure of the core switch is higher than the set temperature threshold of that hardware structure, it is determined that the hardware structure of the core switch has failed. Based on this, it is determined whether the core switch has failed under each load heat dissipation state.

[0045] It should be noted that the temperature thresholds for each hardware structure are referenced in the device user manual or by consulting the device manufacturer.

[0046] In a specific example, the analysis of the cause of the fault is as follows: When the judgment result is that a certain hardware structure of the core switch has failed, the overall temperature and local temperature of the hardware structure of the core switch are obtained through the command line interface of the core switch. When the local temperature of the hardware structure of the core switch is abnormal, it indicates that the hardware has failed. When the overall temperature of the hardware structure of the core switch is abnormal, it indicates that the air-liquid fusion system has failed.

[0047] In a specific instance, the targeted troubleshooting process is as follows: When a hardware structure of the core switch fails, the location and type of the failed hardware structure are obtained through the command-line interface of the core switch, and the hardware structure is disabled. At the same time, traffic is immediately switched to the backup link to prevent data loss, and then relevant personnel are notified to repair the hardware.

[0048] When the air-cooling system of the core switch fails, check if the adjustable speed fan in the air-cooling system is faulty. If the adjustable speed fan is faulty, notify the relevant personnel to repair it. Then check the condition of the coolant in the liquid-cooling system. If the coolant is aged, notify the relevant personnel to replace the coolant.

[0049] This application provides a heat dissipation structure and control method for air-liquid fusion in communication equipment. By analyzing the operating temperature of each hardware structure inside the core switch, the required air-liquid fusion heat dissipation hardware structure is obtained, thereby determining the installation path of the liquid cooling pipes inside the core switch. Then, the optimal adjustment parameters of the air-liquid fusion system under various loads are analyzed through experiments, and the heat dissipation of the air-liquid fusion system is controlled based on the optimal adjustment parameters. The method of obtaining the optimal parameter set through experiments can be customized for different devices, enabling the air-liquid fusion system to flexibly adapt to the heat dissipation requirements of various core switches, thereby improving the versatility and applicability of the system.

[0050] The above content is merely an example and illustration of the concept of this application. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the inventive concept or exceed the scope defined in this application, they should all fall within the protection scope of this application.
