Specifically, the utility model also provides a control method of the controller, which specifically comprises the following steps:
initially, the liquid pump 6 is in a stop state, a large amount of heat is generated by the distribution network communication module 4 in the working process, so that the temperature of the distribution network communication module 4 rises, the temperature of the heat conducting plate 3 rises along with the temperature rise, the temperature sensor assembly 19 detects the temperature of the heat conducting plate 3 in real time, the detected temperature value is fed back to the main control module, the main control module compares the detected temperature with a preset first preset temperature value, and when the detected temperature value is larger than the first preset temperature value, the main control module controls the liquid pump 6 to start and controls the four-way electromagnetic valve 7 and the three-way electromagnetic valve to be started, and the liquid pump 6 drives cooling liquid to circularly flow between the sealing cover 5 and the accommodating cavity 16;
when the cooling liquid carrying heat flows into the accommodating cavity 16, the backboard 29 has good heat dissipation performance and the backboard 29 has a larger heat dissipation area, and the temperature of the cooling liquid in the accommodating cavity 16 is higher than the external environment temperature, so that the backboard 29 can rapidly and efficiently dissipate heat, the cooling liquid in the accommodating cavity 16 is rapidly cooled down, the cooled cooling liquid flows back into the sealing cover 5, and the circulation is performed, so that the heat generated by the network communication module 4 can be rapidly dissipated out of the box body 1;
because the working states of the distribution network communication modules 4 are different, the temperature rising conditions of the distribution network communication modules 4 are different, and for the distribution network communication modules 4 which do not need to dissipate heat and cool, the cooling liquid can not flow through the corresponding sealing covers 5, but is intensively conveyed to the distribution network communication modules 4 which need to cool, so that the cooling mode can be flexibly selected according to the working condition difference of the distribution network communication modules 4, the application of the device is more flexible, and the diversified cooling requirements are met.
Specifically, in this embodiment, since each seal cover 5 is connected with a branch pipe, the flow direction of the cooling liquid can be controlled according to different conditions, which is specifically as follows:
when the temperature detected by only one group of temperature sensor assemblies 19 is too high, the situation that the distribution network communication module 4 in the area where the temperature sensor assemblies 19 are located has high temperature and needs to dissipate heat and cool is indicated, at the moment, the main control module controls the four-way electromagnetic valve 7 to enable the branch pipe of the sealing cover 5 corresponding to the distribution network communication module 4 to be conducted, controls the three-way electromagnetic valve to enable the sealing cover 5 to be conducted with the accommodating cavity 16, cooling liquid can only circulate between the sealing cover 5 and the accommodating cavity 16 after the liquid pump 6 is started, the cooling liquid in a low-temperature state can flow to the sealing cover 5 in a concentrated mode, the situation that the distribution network communication module 4 is subjected to targeted concentrated heat dissipation and cooling is guaranteed, local overheating in the area is avoided, the distribution network communication module 4 is effectively protected, and the distribution network communication module 4 is prevented from being high Wen Shousun;
when the temperature detected by at least two groups of temperature sensor assemblies 19 is too high, the main control conducts the sealing cover 5 of the corresponding area with the accommodating cavity 16 through the control of the four-way electromagnetic valve 7 and the three-way electromagnetic valve, the liquid pump 6 drives cooling liquid to circularly flow in the sealing cover 5 and the accommodating cavity 16, and the simultaneous heat dissipation and cooling of each group of network communication modules 4 are realized, so that the overall rapid heat dissipation and cooling in the box body 1 are facilitated.
Particularly, when the external temperature is low, the low temperature may affect the normal operation of the distribution network communication module 4, and because the heat productivity of each distribution network communication module 4 during operation is different, the heat of the distribution network communication module 4 with high temperature can be partially transferred to the distribution network communication module 4 with low temperature in the low temperature environment, so as to heat the low temperature distribution network communication module 4, which is specifically as follows:
the main control module compares the output values of the temperature sensor assemblies 19, and when the temperature value of one group of the temperature sensor assemblies 19 is lower than a preset low temperature value, the main control module indicates that the low temperature condition occurs in the distribution network communication module 4 of the area where the temperature sensor assemblies 19 are positioned, and the main control module needs to heat the distribution network communication module;
at this time, the main control module controls the corresponding electromagnetic valve to enable the liquid outlet of the liquid pump 6 to be communicated with the sealing cover 5 (hereinafter referred to as a high-temperature sealing cover 5) behind the distribution network communication module 4 with the highest temperature, and enable the sealing cover 5 (hereinafter referred to as a low-temperature sealing cover 5) behind the distribution network communication module 4 to be communicated with the high-temperature sealing cover 5 under the low-temperature condition, so that the liquid pump 6 drives the cooling liquid to sequentially flow through the high-temperature sealing cover 5, the low-temperature sealing cover 5 and the accommodating cavity 16;
the cooling liquid absorbs the heat of the high-temperature distribution network communication module 4 when flowing through the high-temperature sealing cover 5, and the heat is released when flowing into the low-temperature sealing cover 5 along with the cooling liquid, so that the low-temperature distribution network communication module 4 is heated, and is separated from a low-temperature condition, and then can work normally.
Particularly, in the process of cooling the liquid of a certain distribution network communication module 4, if the temperature of the distribution network communication module 4 is detected to be still rising, which indicates that the liquid cooling rate at the moment is difficult to meet the requirement of the distribution network communication module 4, the distribution network communication module 4 may be damaged due to continuous heating, and then the controller further controls the cooling, specifically as follows;
in the liquid cooling process, if the main control module detects that the temperature of a certain assembly network communication module 4 (hereinafter referred to as an abnormal assembly network communication module 4) continues to rise to a preset second preset temperature value (the second preset temperature value is larger than the first preset temperature value), at this time, the main control module sends a command to the motor driving module to enable the motor driving module to drive the liquid pump 6 to operate at a higher rotating speed so as to increase the pumping pressure of the cooling liquid, so that the hydraulic pressure in the sealing cover 5 behind the abnormal communication module is increased along with the abnormal assembly network communication module, the corresponding hydraulic pressure sensor 12 on the branch pipe detects the hydraulic pressure of the sealing cover 5 in real time (the hydraulic pressure in the branch pipe can reflect the hydraulic pressure in the sealing cover 5), the hydraulic pressure sensor 12 feeds back the detected hydraulic pressure value to the main control module, and when the hydraulic pressure is increased to the preset pressure, the main control module sends a command to the motor driving module to control the liquid pump 6 to maintain the current rotating speed, so that the cooling liquid is kept at the current pressure;
the cooling liquid in the guide strip 20 pushes the guide strip 20 outwards under the current pressure, so that the guide strip 20 extends towards the front of the heat conducting plate 3; at the same time, the main control module controls the exhaust fan 23 and the exhaust fan 25 to start, external cold air starts to flow into the box body 1 from the air inlet 22, and hot air in the box body 1 starts to be discharged from the air outlet 24, so that upward air flow is generated in the box body 1;
referring to fig. 2, when the rising air flows through the guide strips 20, air vortex (indicated by dotted arrows in fig. 2) is formed, the air flow in the air vortex area can contact with the bottom surface and corner parts of the distribution network communication module 4 and take away heat of the bottom surface and the corner parts, and the air flow not blocked by the guide strips 20 is directly blown to the front surface of the distribution network communication module 4, so that the distribution network communication module 4 can be blown in multiple directions, and a good air cooling effect is achieved;
in addition, the existence of the air vortex can avoid the condition that the bottom surface and corners of the abnormal distribution network communication module 4 cannot be effectively blown due to shielding of other module components of the lower air flow;
when the temperature of the distribution network communication module 4 is lower than a second preset temperature value, the rotation speed of the liquid pump 6 is reduced to the rotation speed required by the liquid cooling mode, the fan stops running, and the guide strip 20 contracts under the action of self elastic force; when the temperature of the distribution network communication module 4 is lower than a first preset temperature, the liquid pump 6 is stopped, and each electromagnetic valve is closed.
In conclusion, the abnormal distribution network communication module 4 can be effectively restrained from further heating up in a mode of combining liquid cooling and multi-azimuth air cooling, and a better protection effect is achieved.
Further, the heat conducting plate 3 comprises a plurality of mutually independent plate bodies, any two adjacent plate bodies are separated by the heat insulating strip 21, and each group of distribution network communication modules 4 and the corresponding sealing covers 5 are arranged on each plate body in a one-to-one correspondence manner.
Further, an auxiliary heat dissipation layer 17 is arranged on one side of the back plate 29 away from the heat conducting plate 3, so that heat dissipation capacity is improved.
Further, the auxiliary heat dissipation layer 17 is a graphite layer, and the heat dissipation performance of the back plate 29 is enhanced by the arrangement of the graphite layer.
Further, the heat radiating fins 18 are arranged in the sealing cover 5, the heat radiating fins 18 are fixed and contacted with the heat conducting plate 3, when the cooling fluid flows through the sealing cover 5, the heat radiating fins 18 can enlarge the heat exchange area in the sealing cover 5, so that the heat on the heat conducting plate 3 can be more efficiently transferred to the cooling fluid, and the heat radiating effect is improved.
Example two
Referring to fig. 4, the present embodiment differs from the first embodiment in that: the upper part of the guide strip 20 in this embodiment is further provided with an elastic telescopic part 28, and the elastic coefficient of the telescopic part 28 is smaller than that of the guide strip 20.
As can be seen from the above description, when the air cooling is performed, the main control module controls the rotation speed of the liquid pump 6 to make the hydraulic pressure of the cooling liquid alternately become larger and smaller above the preset pressure value, so that the telescopic portion 28 of the guide strip 20 is cyclically and alternately lengthened and shortened, the rising height and the downward inclination angle of the guide strip 20 are periodically changed, and the range and the intensity of the air vortex caused by the rising airflow when the rising airflow flows through the guide strip 20 are periodically changed, so that the air cooling effect can be further improved by alternately and effectively blowing all the parts of the abnormal distribution network communication module 4.
