Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power transmission line monitoring, in particular to a wireless communication device. BACKGROUND

[0002] In the field of power transmission line monitoring, wireless communication devices, as the core of self-organizing network transmission systems based on LTE technology, are gradually developing towards miniaturization and low power consumption to adapt to complex and variable monitoring environments. Such devices integrate high-performance CPUs, large-capacity storage chips, and advanced communication mainboards and other key components to ensure efficient and stable data transmission. However, with the increasing integration of functions and data processing capabilities, these components inevitably generate a large amount of heat during operation, posing a serious challenge to the stable operation of the device. Therefore, effectively managing and dissipating the internal heat generated and maintaining each component within an appropriate operating temperature range are key to ensuring the long-term reliable operation of the wireless communication device.

[0003] Traditionally, passive cooling solutions with metal casings and multiple sets of cooling fins are used to meet the cooling needs of wireless communication devices, aiming to achieve heat exchange between the inside and outside of the device through natural convection and heat conduction mechanisms. Although this solution can meet the basic cooling needs to some extent, its cooling efficiency is insufficient in extremely high-temperature environments or when the device is in an overload operating state, making it difficult to effectively control the internal temperature rise, thereby threatening the lifespan and performance of precision electronic components.

[0004] To address the above challenges, existing technologies attempt to introduce active cooling mechanisms and dust screens to improve cooling efficiency and prevent external dust from entering. However, these improved solutions have several limitations in practical applications: on the one hand, while active cooling systems can significantly improve cooling efficiency, they also increase structural complexity and energy consumption, which is undoubtedly a trade-off for wireless communication devices that pursue low power consumption design; on the other hand, while dust screens can effectively prevent dust from entering, they may also reduce cooling efficiency by hindering smooth airflow, and the cleaning and maintenance of dust screens over a long period of operation also become a new problem.

The filter screen 166 can be back-flushed by high-pressure hot air formed in the hot air pipe 163 to realize synchronous cleaning function, and therefore, the use of high-temperature-resistant alloy steel can increase the service life.

[0047] The embodiment of the present application is internally equipped with a cooling assembly, which comprises a heat exchange pipe 7, a first spring 8, a middle cylinder 14, a connecting pipe 15 and a guide pipe 16, the kerosene inside the heat exchange pipe 7 absorbs heat and causes the volume expansion of the kerosene, which pushes the piston 9 upwards and continuously generates upward positive pressure in the inner cavity of the sealing cylinder 6, pushes the sealing plate 22 to move upwards and is combined with the top of the inner wall of the middle cylinder 14 to form a seal, forms a sealed chamber between the inner cavities of the sealing cylinder 6 and the middle cylinder 14, and continuously compresses the gas in the sealed chamber through the piston 9, pushes the sealing pipe 18 upwards through the piston 9, so that the third communication port 13 blocked by the sealing pipe 18 is communicated with the second communication port 11, and the compressed gas enters the guide pipe 16 along the third communication port 13, the side pipe 17 and the connecting pipe 15, so that the guide pipe 16 converts the compressed air into cold air discharged along the cold air pipe 162 and hot air discharged along the hot air pipe 163, the cold air enters the inner cavity of the device and cools the main plate 5, then generates positive pressure in the inner cavity of the device and pushes the one-way cylinder 232 to move outward to discharge the hot air in the inner cavity of the device, so that heat exchange is realized, which greatly improves the cooling capacity of the device and has the advantages of low cost and high efficiency brought by full automation.

[0048] Then, the embodiment of the present application is additionally equipped with a filter screen 166 on the inner wall of the hot air pipe 163, which filters the air entering the inner cavity of the sealing cylinder 6, when the piston 9 moves downwards under the action of the first spring 8, negative pressure is generated, which sucks air from the outside through the hot air pipe 163 and the air outlet 4 and balances the air pressure in the inner cavity of the sealing cylinder 6, at this time, the side of the filter screen 166 facing the air outlet 4 is used to intercept and filter dust in the air, so as to avoid too much dust in the inside of the device, in the exhaust cooling stage, the high-pressure hot air flow in the hot air pipe 163 moves rightward in a spiral, which just passes through the filter screen 166 and synchronously cleans the side of the filter screen 166 used for filtering and intercepting dust, so as to prolong the service life of the filter screen 166 and reduce the maintenance cost of the device.

[0049] Finally, the embodiment of the present application replaces the air inside the device with cold air from the intermediate pipe 161 every time forced cooling is performed, which can reduce the adhesion strength and time of dust on the surface of the main plate 5, the piston 9 moves downwards under the action of the first spring 8 and generates negative pressure to absorb air from the outside, which is filtered through the filter screen 166 to reduce dust, then the pressurized air in the sealing cylinder 6 enters the inside of the device and cooperates with the exhaust valve 23 to "drive away" the original hot air in the inside of the device, which improves the air flow degree in the inside of the device while realizing effective cooling, at the same time, the air is used to drive the flow of dust to reduce the time and strength of the adhesion of the dust to the surface of the main plate 5, so as to realize a low-cost fresh air system, the whole system is automatically triggered by the temperature in the inside of the device and has the advantage of high reliability.

[0050] The exhaust valve 23 comprises a placing pipe 231, the inner wall of the placing pipe 231 movably sleeved with a one-way cylinder 232, the outer diameter of the one-way cylinder 232 is smaller than the inner diameter of the placing pipe 231, one end of the one-way cylinder 232 abuts against the inner wall of the placing pipe 231, the inside of the one-way cylinder 232 movably sleeved with a third spring 233, both ends of the third spring 233 are elastically connected with the placing pipe 231 and the one-way cylinder 232 respectively. The exhaust valve 23 is only responsible for exhaust, when the hot air in the inner cavity of the device is discharged, one path is along the hot air pipe 163, and the other is the one-way cylinder 232 pushed outward by the positive pressure, the one-way cylinder 232 is pulled by the third spring 233, so as to avoid that the external air directly enters the device from here, and causes problems such as dust.

[0051] The piston 9 and the sealing ring 12 are both sealingly sleeved on the inner wall of the sealing cylinder 6, the sealing ring 12 is made of a rubber block, the kerosene is located directly below the piston 9, and the heat exchange pipe 7 is made of a copper pipe. The piston 9 moves upward under the action of the volume expansion of the kerosene, can compress the air in the inner cavity of the sealing cylinder 6, and provides production conditions for the compressed gas entering the inside of the guide pipe 16, and the heat exchange pipe 7 absorbs the heat inside the device and transmits it to the kerosene, so as to achieve the function of synchronous cooling.

[0052] The inner diameter of the middle cylinder 14 is greater than the inner diameters of the connecting pipe 15 and the sealing cylinder 6, the guide columns 21 are arranged in four groups and are fixedly installed on the inner wall of the middle cylinder 14 at equal angles, the diameter of the sealing plate 22 is smaller than the inner diameter of the middle cylinder 14, and the bottom of the sealing plate 22 is fixedly installed with four groups of convex rings movably sleeved on the outer surfaces of the four groups of guide columns 21.

[0053] The connecting pipe 15 can only ventilate downward in one direction, when the piston 9 moves upward, the air pressure generated thereby pushes the sealing plate 22 to move upward and abut against the top of the inner wall of the middle cylinder 14, so as to form a seal and assist the sealing cylinder 6 to form a sealed chamber, and the convex rings at the bottom of the sealing plate 22 make the sealing plate 22 unable to block the connection between the middle cylinder 14 and the sealing cylinder 6 when moving downward, thereby guaranteeing the air inlet balance of the inner cavity of the sealing cylinder 6.

[0054] The outer surfaces of the sealing cylinder 6 and the connecting pipe 15 are both provided with the third communication port 13, the side pipe 17 is in the shape of “U”, one end of the side pipe 17 communicates with the third communication port 13, and the other end of the side pipe 17 directly communicates with the connecting pipe 15. The side pipe 17 directly communicates the sealing cylinder 6 and the connecting pipe 15, is responsible for skipping the middle cylinder 14, and directly introducing the compressed gas in the sealing cylinder 6 into the connecting pipe 15.

[0055] The length of the sealing tube 18 is equal to the length of the piston 9, the axis of the second communication port 11 is parallel to the axis of the third communication port 13, and the diameter of the second communication port 11 is equal to the diameter of the third communication port 13. The sealing tube 18 and the solid part of the piston 9 can be in contact with the inner wall of the sealing cylinder 6 to seal the third communication port 13, and the compressed gas in the sealing chamber can enter the guide pipe 16 through the first communication port 10, the second communication port 11, the third communication port 13, the side pipe 17 and the connecting pipe 15 when the second communication port 11 coincides with the third communication port 13.

[0056] The front shell 1 and the rear shell 2 are installed by bolt pressing, the mainboard 5 is electrically connected with the interface 3, and the surfaces of the front shell 1 and the rear shell 2 are provided with heat dissipation fins. The heat dissipation fins on the surfaces of the front shell 1 and the rear shell 2 are responsible for passive heat dissipation of the device, and can fully meet the cooling requirements of the device under normal use.

[0057] The working principle and process of the embodiment of the application are as follows:

[0058] The wire harness such as network cable and power cable is connected with the interface 3, and the wireless communication device of the embodiment of the application is started, the mainboard 5 starts to generate heat, and the heat is first absorbed by the fins on the surfaces of the front shell 1 and the rear shell 2 and is consumed through natural air convection.

[0059] When the device is in a high-temperature or high-load operation condition, the internal temperature rises and cannot be absorbed in time by the fins, at this time, the heat exchange pipe 7 starts to work and continuously absorbs heat to the kerosene in the inner cavity, the kerosene expands under the heat and pushes the piston 9 and the sealing ring 12 upwards, the sealing plate 22 moves upwards under the action of the air pressure generated by the upward pushing of the piston 9 and abuts against the bottom of the inner wall of the middle cylinder 14, forming a seal, at this time, the upper part of the inner cavity of the sealing cylinder 6 is sealed by the sealing tube 18 and the sealing plate 22, and a sealing chamber with gradually decreasing volume is formed, and the air in the sealing chamber is compressed under the action of the upward movement of the piston 9, and the pressure gradually increases.

[0060] When the piston 9 and the sealing ring 12 move to abut against the sealing pipe 18, the sealing ring 12 is extruded and deformed, thereby forming a seal between the sealing pipe 18 and the piston 9, the piston 9 and the sealing pipe 18 move upward at the same time, continuously blocking the third communication port 13, until the second communication port 11 moves to the height of coinciding with the third communication port 13, the high-pressure gas in the sealing cavity chamber enters the connecting pipe 15 along the third communication port 13 and the side pipe 17, and then enters the guide pipe 16, the high-pressure gas enters the inner wall of the intermediate pipe 161 and the hot air pipe 163 in a tangent direction under the guidance of the vortex pipe 164, and moves spirally to the right along the inner wall of the hot air pipe 163, and generates heat by rubbing against the inner wall of the hot air pipe 163, and at the same time, the high-pressure gas generates a vortex on the inner wall of the hot air pipe 163, so that a pressure difference is generated in the hot air pipe 163, the gas in the outer ring is high-pressure, the hot air flows to the outer ring, and the cold air flows in the ring, the hot air is discharged through the air outlet 4 on the right side, and the cold air is blocked by the central solid part of the filter screen 166 to flow back to the cold air pipe 162, and enters the inner cavity of the rear shell 2, on the one hand, the cold air cools the main board 5 in the device, and at the same time, the cold air generates a positive pressure in the device, pushes the one-way cylinder 232 to move outward, stretches the third spring 233, opens the opening of the placement pipe 231, and discharges the hot air in the device, and completes heat exchange.

[0061] Finally, the device is cooled, the volume of kerosene is contracted, the first spring 8 drives the piston 9 to move downward and reset, and generates a downward negative pressure in the inner cavity of the sealing cylinder 6, at this time, the third spring 233 is sucked into the inside of the placement pipe 231, the external air enters the vortex pipe 164 through the air outlet 4, is filtered, and then enters the inside of the sealing cylinder 6, when the piston 9 moves upward, the sealing plate 22 moves upward again and blocks the inner cavity of the sealing cylinder 6, when the hot air in the vortex pipe 164 is discharged outward, the filter screen 166 is cleaned.

[0062] From the above description, compared with the prior art, the beneficial effects brought by the embodiment of the present application are that: the present application uses the principle of kerosene heat absorption expansion to drive the movement of the piston to form a sealed chamber and continuously compress the internal gas through the built-in cooling assembly, not only realizes the separation and discharge of cold and hot air, but also efficiently cools the mainboard, significantly improves the cooling efficiency and automation level of the device, and reduces the cost. At the same time, the filter screen embedded in the hot air pipe not only ensures air circulation, but also effectively filters external dust and reduces internal dust accumulation; its unique right spiral high-pressure hot air flow design automatically cleans the filter screen during the exhaust process, prolongs the service life, and further reduces the maintenance cost. In addition, when the present application performs forced cooling, it can automatically replace the air inside the device, introduce filtered cold air, and effectively discharge hot air with the exhaust valve, not only enhancing air flow, but also using air flow characteristics to reduce dust adhesion on the mainboard, realizing the function of a low-cost fresh air system. The present application is automatically triggered by the internal temperature of the device, is highly reliable, and does not require manual intervention, thereby comprehensively improving the performance, maintenance convenience and service life of the device, providing a strong guarantee for the efficient and stable operation of electronic equipment, and is an innovative technical solution that integrates efficient cooling, automatic dust removal and low-cost maintenance.
