Description

Technical Field

[0001] This invention relates to a security protection device for 5G distribution network communication, belonging to the field of distribution network communication technology. Background Technology

[0002] 5G networks are the fifth generation of mobile communication networks, with a peak theoretical transmission speed of up to 1GB per 8 seconds, hundreds of times faster than 4G networks. Compared with previous generations of mobile communication technologies, 5G features ultra-large bandwidth, ultra-high speed, ultra-low latency, and ultra-high connectivity, which helps improve power quality and the flexibility of power systems.

[0003] Because 5G distribution network communication equipment operates at a very high frequency, it will inevitably generate a lot of heat during operation. Most existing 5G distribution network communication equipment has poor heat dissipation. Prolonged use can easily cause the internal temperature of the equipment to become too high, which can damage the internal circuits and electronic components and affect the use of the communication equipment.

[0004] A distribution network communication equipment cabinet disclosed in Chinese utility model patent with publication number CN208766363U includes a top cover, a cabinet body, a main cabinet door, a side cabinet door, a horizontal partition, a vertical partition, a bottom plate, a battery, a cooling fan, and an optical network unit. The top cover is welded to the top of the cabinet body. The front of the cabinet body is an installation area. The surface of the installation area is connected to the main cabinet door by a hinge. The surface of the bottom plate is threaded with two vertical partitions, which are connected by a horizontal partition to divide the cabinet into three layers. The bottom layer of the cabinet body houses the battery, and the top layer is a reserved layer. The outer side of the horizontal partition corresponds to the installation area.

[0005] The above-mentioned example only uses cooling fans for air cooling, which is not only slow and ineffective, but also cannot accurately cool the network communication components inside the cabinet, which can easily cause damage to the components. Therefore, improvements are urgently needed. Summary of the Invention

[0006] To overcome the shortcomings of existing distribution network communication equipment cabinets, such as the inability to provide targeted heat dissipation based on the heat generation of distribution network communication equipment, slow heat dissipation speed, and poor heat dissipation effect, this invention designs a safety protection device for 5G distribution network communication, which can effectively improve the heat dissipation rate of 5G distribution network communication devices and prevent 5G distribution network communication devices from being damaged due to high temperature.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A safety protection device for 5G distribution network communication includes a housing and a controller. A vertically arranged heat-conducting plate is fixed inside the housing. Several sets of distribution network communication modules are fixed at vertical intervals along one side of the heat-conducting plate, and several temperature sensor assemblies are also fixed on the heat-conducting plate. Each temperature sensor assembly corresponds one-to-one with a distribution network communication module. A circulating cooling mechanism is provided on the other side of the heat-conducting plate. The circulating cooling mechanism and each temperature sensor assembly are electrically connected to the controller. The controller is used to control the circulating cooling mechanism to dissipate heat from the distribution network communication module corresponding to the respective temperature sensor assembly based on the temperature data emitted by the temperature sensor assembly.

[0009] Furthermore, the circulating cooling mechanism includes a back plate, a liquid pump, and several sealing covers. The back plate is fixed inside the housing and has a receiving cavity inside. Coolant is provided in both the receiving cavity and each sealing cover. Each sealing cover is sealed and installed on the side of the heat-conducting plate away from the power distribution communication module, and the installation position of each sealing cover corresponds one-to-one with the installation position of each power distribution communication module. Each sealing cover is connected to the outlet of the liquid pump through a branch pipe. Each branch pipe is equipped with an electrically controlled valve for controlling the on / off state of the corresponding branch pipe. The inlet of the liquid pump is connected to the receiving cavity. Any two adjacent sets of sealing covers are connected through a three-way solenoid valve, and the third port of each three-way solenoid valve is connected to the receiving cavity. The liquid pump, the electrically controlled valve, and each three-way solenoid valve are all electrically connected to the controller.

[0010] Furthermore, each of the branch pipes is equipped with a hydraulic sensor for detecting the cooling hydraulic pressure inside the pipe, and the hydraulic sensor is electrically connected to the controller.

[0011] Furthermore, the heat-conducting plate has several through holes that communicate with each sealing cover. The side of the through hole near the distribution network communication module is covered with a guide strip. The guide strip is sealed to the heat-conducting plate, and the cross-sectional shape of the guide strip is arc-shaped.

[0012] Furthermore, an air inlet is provided at the bottom of the enclosure and on the side of the power distribution communication module, and an exhaust fan is installed at the air inlet. An exhaust outlet is provided at the top of the enclosure and directly above the air inlet, and an exhaust fan is installed at the exhaust outlet. Both the exhaust fan and the exhaust fan are electrically connected to the controller. The controller controls the exhaust fan and the exhaust fan to start when the guide strip is squeezed by the coolant and extends away from the sealing cover.

[0013] Furthermore, the heat-conducting plate comprises multiple independent plates, with any two adjacent plates separated by a heat insulation strip, and each set of distribution network communication modules and corresponding sealing covers are installed on each plate.

[0014] Furthermore, an auxiliary heat dissipation layer is provided on the side of the back plate away from the heat-conducting plate.

[0015] Furthermore, the auxiliary heat dissipation layer is a graphite layer.

[0016] Furthermore, a heat sink is provided inside the sealing cover, and the heat sink is fixed and in contact with the heat-conducting plate.

[0017] Furthermore, the upper part of the guide strip is also provided with an elastic telescopic part, the elastic coefficient of the telescopic part being less than the elastic coefficient of the guide strip.

[0018] Compared with the prior art, the present invention has the following features and beneficial effects:

[0019] 1. This invention, by setting up a controller, a temperature sensor, and multiple solenoid valves, allows the controller to determine the temperature anomaly of a specific distribution network communication module based on the temperature detected by the temperature sensor. The controller then controls the opening and closing of the corresponding solenoid valves to achieve precise heat dissipation and cooling of that distribution network communication module, greatly improving heat dissipation efficiency and effectively preventing damage caused by overheating of the distribution network communication equipment. Simultaneously, when one or more distribution network communication modules are at low temperatures, the controller can control the opening and closing of the corresponding solenoid valves to transfer the hot coolant from the currently operating heat-generating distribution network communication module to the corresponding low-temperature distribution network communication module. This heats the low-temperature distribution network communication module, bringing it out of its low-temperature state and into its normal operating temperature range, thereby improving the overall operational stability of the distribution network communication module and its protection against low-temperature environments.

[0020] 2. This invention achieves hybrid heat dissipation for 5G distribution network communication modules by combining liquid cooling and multi-directional air cooling. The coolant plays the primary cooling role, while a heat-conducting plate, backplate, and auxiliary heat dissipation layer work together to achieve primary cooling of the distribution network communication module. When the coolant's heat dissipation capacity reaches its limit, a fan is activated via a controller to achieve air cooling. A hydraulic sensor allows the controller to control the hydraulic pressure of the coolant in the pipes simultaneously with the fan activation, causing the guide strips to bulge and change the fan's airflow direction. The rising airflow then passes over the guide strips... This creates air vortices, allowing the airflow in these vortex areas to contact and remove heat from the bottom and corners of the distribution network communication module. Meanwhile, the airflow not blocked by the guide strips blows directly onto the front surface of the module, achieving comprehensive air cooling and providing excellent temperature control. The combination of coolant and air cooling improves the heat dissipation rate of the 5G distribution network communication module, effectively preventing high temperatures and protecting it from damage.

[0026] The present invention will now be described in more detail with reference to the embodiments.

[0027] Example 1

[0028] like Figures 1-2 As shown, the 5G distribution network communication security protection device of this embodiment includes a housing 1 and a controller. A vertically arranged heat-conducting plate 3 is fixed inside the housing 1. Three sets of distribution network communication modules 4 are fixed at vertical intervals on one side of the heat-conducting plate 3 (in other embodiments, the number of distribution network communication modules 4 can also be two, four or more sets). The distribution network communication modules 4 are in contact with the heat-conducting plate 3, so that the heat on the distribution network communication modules 4 can be conducted to the heat-conducting plate 3. Three temperature sensor assemblies 19 are also fixed on the heat-conducting plate 3. The three temperature sensor assemblies 19 are arranged one-to-one with the three distribution network communication modules 4. A circulating cooling mechanism is provided on the other side of the heat-conducting plate 3. The circulating cooling mechanism and each temperature sensor assembly 19 are electrically connected to the controller. The controller is used to control the circulating cooling mechanism to dissipate heat from the distribution network communication module 4 corresponding to the temperature sensor assembly 19 according to the temperature data emitted by the temperature sensor assembly 19.

[0029] Furthermore, the circulating cooling mechanism includes a back plate 29, a liquid pump 6, and three sealing covers 5. The back plate 29 is fixed inside the housing 1, and a receiving cavity 16 is provided inside the back plate 29. Coolant is provided in both the receiving cavity 16 and each sealing cover 5. Each sealing cover 5 is sealed and installed on the side of the heat-conducting plate 3 away from the power distribution communication module 4, thereby forming a sealed space between the sealing cover 5 and the heat-conducting plate 3. The installation position of each sealing cover 5 corresponds one-to-one with the installation position of each power distribution communication module 4. Each sealing cover 5 is connected to the outlet of the liquid pump 6 through a branch pipe. Each branch pipe is equipped with an electric control valve for controlling the on / off of the corresponding branch pipe. The inlet of the liquid pump 6 is connected to the receiving cavity 16. Any two adjacent sets of sealing covers 5 are connected through a three-way solenoid valve, and the third port of each three-way solenoid valve is connected to the receiving cavity 16. The liquid pump 6, the electric control valve, and each three-way solenoid valve are all electrically connected to the controller.

[0030] Specifically, a liquid pump 6, a first branch pipe 9, a second branch pipe 10, and a third branch pipe 11 are installed inside the housing 1. A receiving cavity 16 is provided inside the back plate 29 of the housing 1. The back plate 29 is made of a high thermal conductivity material to give it good heat dissipation performance. The outlet of the liquid pump 6 is connected to the first port of the four-way solenoid valve 7 through the outlet pipe 8. The inlet of the liquid pump 6 is connected to the inside of the receiving cavity 16 through a pipe. One end of the first branch pipe 9 is connected to the second port of the four-way solenoid valve 7, and the other end is connected to the inside of the first set of sealing covers 5. One end of the second branch pipe 10 is connected to the third port of the four-way solenoid valve 7, and the other end is connected to the inside of the second set of sealing covers 5. One end of the third branch pipe 11 is connected to the fourth port of the four-way solenoid valve 7, and the other end is connected to the inside of the third set of sealing covers 5.

[0031] A three-way solenoid valve I13 is provided between the first group of sealing covers 5 and the second group of sealing covers 5. The first port of the three-way solenoid valve I13 is connected to the inside of the first group of sealing covers 5, the second port of the three-way solenoid valve I13 is connected to the inside of the second group of sealing covers 5, and the third port of the three-way solenoid valve I13 is connected to the inside of the receiving cavity 16 through the return pipe 15. A three-way solenoid valve II14 is provided between the second group of sealing covers 5 and the third group of sealing covers 5. The first port of the three-way solenoid valve II14 is connected to the inside of the second group of sealing covers 5, the second port of the three-way solenoid valve II14 is connected to the inside of the third group of sealing covers 5, and the third port of the three-way solenoid valve II14 is connected to the inside of the receiving cavity 16 through the return pipe 15.

[0032] Furthermore, each branch pipe is equipped with a hydraulic sensor 12 for detecting the hydraulic pressure of the cooling fluid inside the pipe, and the hydraulic sensor 12 is electrically connected to the controller.

[0033] Furthermore, the heat-conducting plate 3 has several through holes 27 that communicate with each sealing cover 5. The side of the through hole 27 closest to the distribution network communication module 4 is covered with a guide strip 20. The guide strip 20 is sealed to the heat-conducting plate 3, and the cross-sectional shape of the guide strip 20 is arc-shaped. The coolant passes through the through hole 27 and enters the guide strip 20.

[0034] Furthermore, an air inlet 22 is provided at the bottom of the enclosure 1 and on the side of the power distribution communication module 4. An exhaust fan 23 is installed at the air inlet 22. An exhaust outlet 24 is provided at the top of the enclosure 1 and directly above the air inlet 22. An exhaust fan 25 is installed at the exhaust outlet 24. Both the exhaust fan 23 and the exhaust fan 25 are electrically connected to the controller. The controller starts the exhaust fan 23 and the exhaust fan 25 when the guide strip 20 is squeezed by the coolant and extends away from the sealing cover 5.

[0035] Specifically, refer to Figure 3 The controller includes a main control module, as well as a motor drive module, a power supply module, and a communication module connected to the main control module. The motor drive module is connected to the liquid pump 6 and is used to drive the liquid pump 6; the communication module is used to communicate with external devices; and the power supply module is used to supply power.

[0036] The controller also includes a fan drive module. The input end of the fan drive module is connected to the control signal output end of the main control module, and the drive end of the fan drive module is connected to the exhaust fan 23 and the exhaust fan 25 to drive the exhaust fan 23 and the exhaust fan 25 to rotate.

[0037] The output terminals of each temperature sensor assembly 19 are connected to the sampling port of the main control module; the control terminals of the three-way solenoid valve I 13, the three-way solenoid valve II 14, and the four-way solenoid valve 7 are connected to the control signal output terminal of the main control module; the output terminal of the hydraulic sensor 12 is connected to the sampling port of the main control module.

[0038] Specifically, the present invention also provides a control method for the controller, as follows:

[0039] Initially, the liquid pump 6 is in a stopped state. During the operation of the distribution network communication module 4, a large amount of heat is generated, causing the temperature of the distribution network communication module 4 to rise, which in turn causes the temperature of the heat conduction plate 3 to rise. The temperature sensor assembly 19 detects the temperature of the heat conduction plate 3 in real time and feeds back the detected temperature value to the main control module. The main control module compares the detected temperature with the preset first temperature value. When the detected temperature value is greater than the first preset temperature value, the main control module controls the liquid pump 6 to start and controls the four-way solenoid valve 7 and the three-way solenoid valve to open. The liquid pump 6 drives the coolant to circulate between the sealing cover 5 and the accommodating cavity 16.

[0040] The heat from the distribution network communication module 4 is conducted to the heat conduction plate 3, and the heat from the heat conduction plate 3 is conducted to the coolant in the sealing cover 5. When the coolant carrying heat flows into the accommodating cavity 16, the back plate 29 has good heat dissipation performance and a large heat dissipation area, and the temperature of the coolant in the accommodating cavity 16 is higher than the external ambient temperature. Therefore, the back plate 29 can dissipate heat quickly and efficiently, so that the coolant in the accommodating cavity 16 can be cooled down quickly. The cooled coolant then flows back into the sealing cover 5. This cycle is repeated, so that the heat generated by the distribution network communication module 4 can be quickly dissipated to the outside of the enclosure 1.

[0041] Since the working states of each distribution network communication module 4 are different, the temperature rise of each distribution network communication module 4 will also be different. For distribution network communication modules 4 that do not require heat dissipation and cooling, the coolant can be directed to the distribution network communication modules 4 that need cooling instead of flowing through their corresponding sealing cover 5. This allows for flexible selection of cooling mode based on the different working conditions of each distribution network communication module 4, making the application of the device more flexible and meeting diverse cooling needs.

[0042] Specifically, in this embodiment, since each sealing cover 5 is connected to a branch pipe, the flow direction of the coolant can be controlled according to different situations, as follows:

[0043] When only one set of temperature sensor components 19 detects an excessively high temperature, it indicates that the distribution network communication module 4 in the area where the temperature sensor component 19 is located has a high temperature and needs to be cooled down. At this time, the main control module controls the four-way solenoid valve 7 to make the branch pipe of the sealing cover 5 corresponding to the distribution network communication module 4 open, and controls the three-way solenoid valve to make the sealing cover 5 open with the accommodating cavity 16. After the liquid pump 6 starts, the coolant can only circulate between the sealing cover 5 and the accommodating cavity 16, which can make the coolant at low temperature flow to the sealing cover 5, ensuring targeted and concentrated heat dissipation and cooling of the distribution network communication module 4, avoiding local overheating in this area, effectively protecting the distribution network communication module 4, and preventing the distribution network communication module 4 from being damaged by high temperature.

[0044] When at least two sets of temperature sensor components 19 detect excessively high temperatures, the main controller controls the four-way solenoid valve 7 and the three-way solenoid valve to connect the sealing cover 5 and the accommodating cavity 16 in the corresponding area. The liquid pump 6 drives the coolant to circulate within the sealing cover 5 and the accommodating cavity 16, thereby simultaneously cooling down each set of distribution network communication modules 4, which is beneficial for the rapid cooling down of the entire enclosure 1.

[0045] In particular, when the ambient temperature is low, the low temperature may affect the normal operation of the distribution network communication module 4. Since the heat generated by each distribution network communication module 4 is different during operation, in a low-temperature environment, part of the heat from the higher-temperature distribution network communication module 4 can be transferred to the lower-temperature distribution network communication module 4 to achieve heating of the low-temperature distribution network communication module 4, as follows:

[0046] The main control module compares the output values ​​of each temperature sensor component 19. When the temperature value of a set of temperature sensor components 19 is lower than the preset low temperature value, it indicates that the distribution network communication module 4 in the area where the temperature sensor component 19 is located has a low temperature condition and needs to be heated.

[0047] At this time, the main control module controls the corresponding solenoid valve to make the outlet of the liquid pump 6 connected to the sealing cover 5 (hereinafter referred to as the high temperature sealing cover 5) behind the distribution network communication module 4 with the highest temperature, and to make the sealing cover 5 (hereinafter referred to as the low temperature sealing cover 5) behind the distribution network communication module 4 with the high temperature sealing cover 5. The liquid pump 6 drives the coolant to flow through the high temperature sealing cover 5, the low temperature sealing cover 5 and the accommodating cavity 16 in sequence.

[0048] When the coolant flows through the high-temperature sealing cover 5, it absorbs the heat from the high-temperature distribution network communication module 4. The heat is released when the coolant flows into the low-temperature sealing cover 5, thereby heating the low-temperature distribution network communication module 4, allowing it to escape the low-temperature condition and work normally.

[0049] In particular, during the liquid cooling process of a certain distribution network communication module 4, if the temperature of the distribution network communication module 4 is still rising, it indicates that the liquid cooling rate is no longer sufficient for the distribution network communication module 4, and the distribution network communication module 4 may continue to heat up and be damaged. In this case, the controller will further control the cooling process as follows.

[0050] During the liquid cooling process, if the main control module detects that the temperature of a certain distribution network communication module 4 (hereinafter referred to as abnormal distribution network communication module 4) continues to rise to the second preset temperature value (the second preset temperature value is greater than the first preset temperature value), the main control module sends a command to the motor drive module to drive the liquid pump 6 to run at a higher speed to increase the pumping pressure of the coolant, so that the pressure in the sealing cover 5 behind the abnormal communication module increases accordingly. The hydraulic sensor 12 on the corresponding branch pipe detects the pressure of the sealing cover 5 in real time (the pressure in the branch pipe can reflect the pressure in the sealing cover 5). The hydraulic sensor 12 feeds back the detected pressure value to the main control module. When the pressure increases to the preset pressure, the main control module sends a command to the motor drive module to control the liquid pump 6 to maintain the current speed and keep the coolant at the current pressure.

[0051] Under the current pressure, the coolant in the guide strip 20 pushes the guide strip 20 outward, causing the guide strip 20 to extend in front of the heat conduction plate 3; at the same time, the main control module controls the exhaust fan 23 and the exhaust fan 25 to start, and the outside cold air begins to flow into the box 1 from the air inlet 22, and the hot air in the box 1 begins to be discharged from the exhaust port 24, generating an upward airflow in the box 1.

[0052] Reference Figure 2 The rising airflow will form an air vortex when it flows over the guide strip 20. Figure 2 (As shown by the dashed arrow in the middle), the airflow in the air vortex zone can contact the bottom and corners of the distribution network communication module 4 and carry away the heat from the bottom and corners. The airflow that is not blocked by the guide strip 20 blows directly onto the front surface of the distribution network communication module 4. In this way, the distribution network communication module 4 can be blown from multiple directions, achieving a good air-cooling effect.

[0053] In addition, the presence of air vortexes can prevent the bottom and corners of the abnormal distribution network communication module 4 from being effectively blown away due to the obstruction of airflow by other modules and components below.

[0054] When the temperature of the distribution network communication module 4 is lower than the second preset temperature value, the speed of the liquid pump 6 is reduced to the speed required for liquid cooling mode, the fan stops running, and the guide bar 20 contracts under its own elasticity; when the temperature of the distribution network communication module 4 is lower than the first preset temperature, the liquid pump 6 stops and all solenoid valves close.

[0055] In summary, the combination of liquid cooling and multi-directional air cooling can effectively prevent the abnormal distribution network communication module 4 from overheating, thus achieving a better protection effect.

[0056] Furthermore, the heat-conducting plate 3 includes multiple independent plates, with any two adjacent plates separated by a heat insulation strip 21. Each set of distribution network communication modules 4 and the corresponding sealing cover 5 are installed on each plate. This arrangement can prevent heat transfer between different areas and facilitates the adoption of different liquid cooling modes for each distribution network communication module 4.

[0057] Furthermore, an auxiliary heat dissipation layer 17 is provided on the side of the back plate 29 away from the heat conduction plate 3 to improve heat dissipation capacity.

[0058] Furthermore, the auxiliary heat dissipation layer 17 is a graphite layer, which enhances the heat dissipation performance of the back plate 29.

[0059] Furthermore, a heat sink 18 is provided inside the sealing cover 5. The heat sink 18 is fixed and in contact with the heat conduction plate 3. When the coolant flows through the sealing cover 5, it will come into contact with the heat sink 18. The heat sink 18 can increase the heat exchange area inside the sealing cover 5, so that the heat on the heat conduction plate 3 can be transferred to the coolant more efficiently, thereby improving the heat dissipation effect.

[0060] Example 2

[0061] Reference Figure 4 The difference between this embodiment and embodiment one is that the upper part of the guide strip 20 in this embodiment is also provided with an elastic telescopic part 28, and the elastic coefficient of the telescopic part 28 is less than the elastic coefficient of the guide strip 20.

[0062] As can be seen from the above description, during air cooling, the main control module controls the speed of the liquid pump 6 to make the hydraulic pressure of the coolant alternately increase and decrease above the preset pressure value. This causes the telescopic part 28 of the guide strip 20 to alternately extend and shorten. The bulge height and downward tilt angle of the guide strip 20 change periodically accordingly. The range and intensity of the air vortex caused by the rising airflow passing through the guide strip 20 change periodically accordingly. This allows for alternating and effective blowing on various parts of the abnormal distribution network communication module 4, further improving the air cooling effect.
