Description

Technical Field

[0001] The present invention relates to the technical field of power transmission line monitoring, and in particular to a wireless communication device. Background Art

[0002] In the field of power transmission line monitoring, wireless communication devices, as the core of the self-organizing network transmission system based on LTE technology, are gradually developing in the direction of miniaturization and low power consumption to adapt to the complex and changing monitoring environment. Such devices integrate key components such as high-performance CPUs, large-capacity storage chips and advanced communication motherboards to ensure efficient and stable data transmission. However, with the increase in functional integration and data processing capabilities, these components inevitably generate a large amount of heat energy during operation, posing a severe challenge to the stable operation of the device. Therefore, effectively managing and dissipating the internally generated heat and maintaining each component within a suitable operating temperature range have become the key to ensuring the long-term and reliable operation of wireless communication devices.

[0003] Traditionally, the heat dissipation requirements of wireless communication devices are usually met by a passive cooling solution that uses a metal casing with multiple sets of heat dissipation fins, aiming to achieve heat exchange inside and outside the device through natural convection and heat conduction mechanisms. Although this solution can meet basic heat dissipation requirements to a certain extent, its heat dissipation efficiency is insufficient in extremely high temperature environments or when the device is in an overloaded operating state, making it difficult to effectively control the internal temperature rise, thereby threatening the life and performance of precision electronic components.

[0004] To address the above challenges, existing technologies attempt to introduce active cooling mechanisms and dust screen designs in order to improve heat dissipation efficiency and prevent external dust from entering. However, these improvement schemes have exposed several limitations in practical applications: on the one hand, although the active cooling system can significantly improve the heat dissipation effect, it is accompanied by an increase in structural complexity and an increase in energy consumption, which is undoubtedly a trade-off for wireless communication devices that pursue low-power design; on the other hand, although the dust screen can effectively prevent dust from entering, it may also reduce heat dissipation efficiency by hindering the smooth flow of air. At the same time, the cleaning and maintenance of the dust screen during long-term operation has also become a new problem. Summary of the invention

[0045] The bottom of the inner cavity of the sealing cylinder 6 is elastically connected with the first spring 8, the top of the first spring 8 is elastically connected with the piston 9 and the sealing ring 12, the top and outer surface of the piston 9 are respectively provided with a first connecting port 10 and a second connecting port 11 which are interconnected, a fixing ring 19 is fixedly installed on the top of the inner wall of the sealing cylinder 6, the inner wall sealing sleeve of the sealing cylinder 6 is provided with a sealing tube 18, and a second spring 20 is elastically connected between the sealing tube 18 and the fixing ring 19, a guide column 21 is fixedly installed on the inner wall of the middle cylinder 14, and the outer surface of the guide column 21 is sealingly sleeved with a sealing plate 22.

[0046] The conduit 16 includes an intermediate tube 161, and the left and right ends of the intermediate tube 161 are respectively fixedly connected with a cold air pipe 162 and a hot air pipe 163, one end of the cold air pipe 162 is connected to the inner cavity of the rear housing 2, and one end of the hot air pipe 163 is connected to the air outlet 4. A vortex 164 is fixedly installed inside the intermediate tube 161, and a slot 165 is provided on the inner wall of the hot air pipe 163, and a filter 166 is fixedly installed on the inner wall of the slot 165. The filter 166 is made of metal, and the filter 166 is fixed to the inner wall of the slot 165 by welding. The filter 166 can be recoiled by the high-pressure hot air formed inside the hot air pipe 163 to achieve a synchronous cleaning function, so the use of high-temperature resistant alloy steel can increase its service life.

[0047] In the embodiment of the present invention, a cooling assembly is installed inside, which includes a heat exchange tube 7, a first spring 8, a middle tube 14, a connecting tube 15 and a guide tube 16. The heat exchange tube 7 and the kerosene inside the heat exchange tube 7 absorb heat, and the kerosene volume expands, pushing the piston 9 upward, and continuously generating an upward positive pressure in the inner cavity of the sealing tube 6, pushing the sealing plate 22 upward and concluding on the top of the inner wall of the middle tube 14 to form a seal, forming a sealed chamber between the inner cavities of the sealing tube 6 and the middle tube 14, and continuously compressing the gas in the sealed chamber through the piston 9, pushing the sealed tube 18 upward through the piston 9, so that the sealed tube 18 The blocked third connecting port 13 is connected with the second connecting port 11, and the compressed gas enters the conduit 16 along the third connecting port 13, the side pipe 17, and the connecting pipe 15, so that the conduit 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 down the main board 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 to achieve heat exchange. This design 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 invention further installs a filter 166 on the inner wall of the hot air pipe 163 to filter the air entering the inner cavity of the sealing tube 6. When the piston 9 moves downward under the action of the first spring 8, negative pressure will be generated. The negative pressure will draw air to the outside through the hot air pipe 163 and the air outlet 4, and form an air pressure balance in the inner cavity of the sealing tube 6. At this time, the side of the filter 166 facing the air outlet 4 is used to intercept and filter dust in the air to avoid excessive dust inside the device. In the exhaust cooling stage, a high-pressure hot air flow with a rightward spiral motion is generated inside the hot air pipe 163. The airflow just passes through the filter 166, and the side of the filter 166 used for filtering and intercepting dust is cleaned simultaneously, so that the service life of the filter 166 is extended and the maintenance cost of the device is reduced.

[0049] Finally, the embodiment of the present invention replaces the internal air each time forced cooling is performed, and fills in cold air from the intermediate tube 161, which can reduce the adhesion strength and time of dust on the surface of the mainboard 5. The piston 9 moves downward under the action of the first spring 8 and generates negative pressure to absorb air from the outside, which is filtered through the filter 166 to reduce dust. Then, the pressurized air inside the sealing tube 6 enters the interior of the device and cooperates with the exhaust valve 23 to "drive away" the hot air originally existing in the device. While achieving effective cooling, the air flow inside the device is improved. At the same time, the air is used to drive the dust to flow, reducing the time and intensity of its adhesion to the surface of the mainboard 5, thereby realizing a low-cost fresh air system. The entire system is automatically triggered by the internal temperature of the device, and has the advantage of high reliability.

[0050] The exhaust valve 23 includes a placement tube 231, the inner wall of which is movably sleeved with a one-way tube 232, the outer diameter of which is smaller than the inner diameter of the placement tube 231, one end of which is in contact with the inner wall of the placement tube 231, and a third spring 233 is movably sleeved inside the one-way tube 232, the two ends of which are elastically connected to the placement tube 231 and the one-way tube 232 respectively. The exhaust valve 23 is only responsible for exhausting air, and 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 tube 232 pushed outward by the positive pressure, and the one-way tube 232 is pulled by the third spring 233 to prevent the outside air from directly entering the device from here, causing dust and other problems.

[0051] The piston 9 and the sealing ring 12 are both sealed and 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. The heat exchange tube 7 is made of a copper tube. The piston 9 moves upward under the action of the volume expansion of the kerosene, which can compress the air in the inner cavity of the sealing cylinder 6 and provide production conditions for the compressed gas entering the conduit 16. The heat exchange tube 7 absorbs the heat inside the device and transfers it to the kerosene 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 tube 15 and the sealing cylinder 6. The guide columns 21 are arranged in four groups and fixedly mounted at equal angles on the inner wall of the middle cylinder 14. The diameter of the sealing plate 22 is smaller than the inner diameter of the middle cylinder 14. Four groups of convex rings are fixedly mounted on the bottom of the sealing plate 22 and are movably sleeved on the outer surfaces of the four groups of guide columns 21.

[0053] The connecting pipe 15 can only ventilate in one direction downward. When the piston 9 moves upward, the air pressure it generates will push the sealing plate 22 to move upward and abut against the top of the inner wall of the middle cylinder 14 to form a seal, thereby assisting the inner cavity of the sealing cylinder 6 to form a sealed chamber. The convex ring at the bottom of the sealing plate 22 prevents the sealing plate 22 from blocking the connection between the middle cylinder 14 and the sealing cylinder 6 when moving downward, thereby providing a guarantee for the air intake balance of the inner cavity of the sealing cylinder 6.

[0054] The outer surfaces of the sealing cylinder 6 and the connecting tube 15 are both provided with a third connecting port 13. The side tube 17 is in a "U" shape. One end of the side tube 17 is connected to the third connecting port 13, and the other end of the side tube 17 is directly connected to the connecting tube 15. The side tube 17 directly connects the sealing cylinder 6 and the connecting tube 15, and is responsible for skipping the middle cylinder 14 and directly introducing the compressed gas in the sealing cylinder 6 into the connecting tube 15.

[0055] The length of the sealing tube 18 is equal to that of the piston 9, the axis of the second communication port 11 is parallel to that of the third communication port 13, and the diameters of the second communication port 11 and the third communication port 13 are equal. The solid parts of the sealing tube 18 and the piston 9 can block the third communication port 13 by contacting with the inner wall of the sealing cylinder 6. When the second communication port 11 and the third communication port 13 overlap, they are connected. At this time, the compressed gas in the sealed chamber can enter the conduit 16 along the first communication port 10, the second communication port 11, the third communication port 13, the side pipe 17, and the connecting pipe 15.

[0056] The front housing 1 and the rear housing 2 are assembled by bolts, the mainboard 5 is electrically connected to the interface 3, and the surfaces of the front housing 1 and the rear housing 2 are provided with heat dissipation fins. The heat dissipation fins on the surfaces of the front housing 1 and the rear housing 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 present invention are as follows:

[0058] Connect the network cable, power cable and other wiring harnesses to the interface 3, and start the wireless communication device of the embodiment of the present invention, the mainboard 5 starts to heat up, and the heat is initially absorbed by the fins on the surface of the front shell 1 and the rear shell 2, and is consumed through natural air convection.

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

[0060] When the piston 9 and the sealing ring 12 move to abut against the sealing tube 18, the sealing ring 12 is squeezed and deformed, thereby forming a seal between the sealing tube 18 and the piston 9, and the piston 9 and the sealing tube 18 move upward at the same time to continuously block the third connecting port 13 until the second connecting port 11 moves to a height that coincides with the third connecting port 13. The high-pressure gas in the inner cavity of the sealed chamber enters the connecting pipe 15 along the third connecting port 13 and the side pipe 17, and then enters the conduit 16. Under the guidance of the vortex tube 164, the high-pressure gas enters the inner wall of the intermediate tube 161 and the hot gas pipe 163 in a tangential direction, and moves spirally to the right along the inner wall of the hot gas pipe 163, and is in contact with the inner wall of the hot gas pipe 163. Friction generates heat, and at the same time, a vortex is formed on the inner wall of the hot air pipe 163, which causes a pressure difference inside the hot air pipe 163. The gas in the outer circle is high pressure, and the hotter air flows to the outer circle, while the cold air flows inside the circle. The hot air is discharged through the air outlet 4 along the right side, and the cold air is blocked by the central solid part of the filter 166 and flows 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 inside the device, and at the same time generates positive pressure inside the device, pushing the one-way cylinder 232 to move outward, and stretching the third spring 233, opening the opening of the placement tube 231, and discharging the hot air inside the device to complete the heat exchange.

[0061] Finally, the temperature inside the device drops, the volume of kerosene shrinks, the first spring 8 drives the piston 9 to move downward and reset, and generates downward negative pressure in the inner cavity of the sealing tube 6. At this time, the third spring 233 is sucked into the interior of the placement tube 231, and the outside air enters the vortex 164 through the air outlet 4 and is filtered, and then enters the interior of the sealing tube 6. When the piston 9 moves upward, the sealing plate 22 moves upward again and blocks the inner cavity of the sealing tube 6. When the hot air is discharged from the interior of the vortex 164, the filter screen 166 is cleaned by the way.

[0062] It can be seen from the above description that compared with the prior art, the beneficial effects brought by the embodiments of the present invention are: the present invention uses the principle of kerosene endothermic expansion through a built-in cooling component to drive the piston to move to form a sealed chamber and continuously compress the internal gas, which 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 effectively filters external dust and reduces internal dust accumulation while ensuring air circulation; its unique right-hand 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 performing forced cooling, the present invention can automatically replace the air inside the device, introduce filtered cold air, and cooperate with the exhaust valve to effectively remove hot air, which not only enhances air flow, but also uses the air flow characteristics to reduce the adhesion of dust on the mainboard, and realizes the function of a low-cost fresh air system. The present invention is automatically triggered by the internal temperature of the device, is highly reliable, does not require human intervention, and comprehensively improves the performance, maintenance convenience and service life of the device, providing a strong guarantee for the efficient and stable operation of electronic equipment. It is an innovative technical solution that integrates efficient cooling, automatic dust removal, and low-cost maintenance.

[0063] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
