Abstract
Description
Technical Field
[0001] This invention relates to the field of aviation obstruction light technology, specifically a self-cooling aviation obstruction light. Background Technology
[0002] In the field of aviation obstruction light technology, aviation obstruction lights, as crucial equipment for ensuring flight safety, are widely used on various tall buildings, communication towers, chimneys, and other obstacles to warn pilots of their presence. However, aviation obstruction lights generate a significant amount of heat during operation, especially during prolonged continuous operation, causing a substantial increase in the temperature of the light body and its internal electronic components. High temperatures not only affect the luminous efficiency and stability of the aviation obstruction lights but may also accelerate the aging of electronic components and even lead to equipment malfunctions, thus seriously impacting flight safety.
[0003] Traditional aviation obstruction lights primarily rely on natural convection or simple fan cooling for heat dissipation. These methods often prove ineffective in high-temperature environments or when airflow is poor. Specifically, natural convection cooling is highly dependent on ambient temperature; its effectiveness is almost negligible when the ambient temperature approaches or exceeds the light's temperature. While simple fan cooling can accelerate airflow and improve efficiency to some extent, in high-temperature environments, the hot air blown out by the fan may actually exacerbate the internal temperature rise, creating a vicious cycle.
[0004] Furthermore, while some existing self-cooling aviation obstruction lights employ semiconductor cooling technology, they have some design shortcomings. For example, some designs do not adequately consider the smoothness of airflow, leading to easy clogging of the filter holes and affecting heat dissipation; others have complex heat dissipation structures, requiring intricate piping systems and large amounts of coolant, increasing manufacturing costs and maintenance difficulty. Still other designs cannot effectively prevent external air impurities from entering the equipment during heat dissipation, damaging electronic components and reducing the equipment's reliability and lifespan.
[0005] Based on this, a self-cooling aviation obstruction light is now provided, which can eliminate the drawbacks of existing aviation obstruction lights. Summary of the Invention

The outer diameter of the top plate is equal to the inner diameter of the filter cylinder. The heat dissipation cavity, control cavity, connecting seat and filter cartridge are equipped with a cooling structure, which is electrically connected to the controller; The cooling structure includes an exchange component and a rotating component. The cooling structure uses the exchange component to cool the gas cooled by the semiconductor cooling chip to the controller in the control cavity and the heat dissipation fins in the heat dissipation cavity. The cooling structure uses the rotating component to rotate the filter cartridge. Two cleaning scrapers are symmetrically fixed between the lower end of the lamp holder and the upper end of the base. The two cleaning scrapers are in contact with the outer wall of the filter cartridge, and the two cleaning scrapers work with the rotating part of the cooling structure to clean the filter cartridge.
[0008] Preferably, the rotating component of the cooling structure includes a motor mounted on the inner wall of the connecting seat, the output end of the motor is fixedly connected to a gear, the gear is rotatably mounted on the upper end of the top plate, the gear meshes with an internal gear ring, and the internal gear ring is fixedly mounted on the upper end of the filter cartridge.
[0009] Preferably, the internal gear ring meshes with the second gear, the second gear is rotatably mounted on the upper end of the top plate, and the lower middle part of the second gear extends to the lower end of the top plate via a connecting rod and is fixedly connected to the exhaust fan, the exhaust fan being located at the cooling end of the semiconductor refrigeration chip.
[0010] Preferably, an air blowing pipe is installed inside the filter cartridge, with an air inlet at the upper end of the air blowing pipe. There is a gap between the upper air inlet of the air blowing pipe and the lower end of the top plate. The lower middle part of the gear extends into the air blowing pipe through a connecting rod and is fixedly connected to a blower fan. Several air blowing heads facing the filter holes of the filter cartridge are fixed on the side wall of the air blowing pipe.
[0011] Preferably, the exchange component includes air pipe one, air pipe two, air pipe three, air pipe four and air pipe five. The air inlet end of air pipe one extends through the top plate into the interior of the filter cartridge, and the air inlet end of air pipe one is located at the cooling end of the semiconductor refrigeration chip.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. During the cooling process, the present invention drives gear one to rotate via a motor. The meshing of gear one with the internal gear ring drives the filter cartridge to rotate. At the same time, the internal gear ring drives gear two to rotate, which in turn drives the exhaust fan to work. The exhaust fan, in conjunction with the semiconductor cooling chip, draws cold air into the air pipe of the heat exchanger to achieve heat dissipation and cooling of the aviation obstruction light. During the rotation of the filter cartridge, the cleaning scraper continuously scrapes away the dust and debris attached to the outer wall of the filter cartridge, effectively preventing the filter holes from becoming clogged and ensuring smooth airflow. While the filter cartridge is rotating, the high-speed airflow generated by the blower blows the air blower head on the air blower pipe in a directional manner towards the filter holes, blowing off the dust and debris attached to the filter holes and ensuring the long-term unobstructed flow of the filter holes.
[0017] 2. This invention monitors the temperature inside the heat dissipation cavity and control cavity in real time using a temperature sensor and feeds the data back to the controller. When the temperature reaches a preset threshold, the controller automatically activates the semiconductor cooling chip to cool the equipment, thus preventing equipment failure or performance degradation due to high temperature. It also reduces the complex pipes and large amount of coolant required by traditional cooling systems, simplifies the equipment structure, and reduces manufacturing costs and maintenance difficulty.
[0018] 3. The exchange component of this invention adopts a multi-pipe design, forming an optimized airflow path. Low-temperature gas enters the heat dissipation cavity and control cavity from the cooling end of the semiconductor refrigeration chip, absorbs heat, and then flows back to the heating end of the semiconductor refrigeration chip through the pipes to be discharged, achieving efficient heat exchange. At the same time, the planar spiral structure design of the pipes further increases the heat exchange area and improves the cooling effect. The gas flows in multiple pipes, preventing external gas from directly entering the aviation obstruction light, thereby avoiding damage to the electronic components inside the aviation obstruction light caused by external air impurities.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0025] In one embodiment, such as Figures 1-4 As shown, a self-cooling aviation obstruction light includes a base 1, a filter cartridge 2, a connecting seat 11, a lamp holder 12, and a lamp body 13. The lamp body 13 is mounted on the upper end of the lamp holder 12. The lamp holder 12 is divided into a heat dissipation cavity 123 and a control cavity 122 by a fixed partition 121. The lamp body 13 has heat dissipation fins 131 fixed inside the heat dissipation cavity 123. A controller 124 is installed in the control cavity 122. Temperature sensors are installed in both the heat dissipation cavity 123 and the control cavity 122. The temperature sensors are electrically connected to the controller 124. The connecting seat 11 is fixedly installed in the middle of the lower end of the lamp holder 12. A base 1 is provided directly below the connecting seat 11. A filter cartridge 2 is rotatably installed between the connecting seat 11 and the base 1. A semiconductor cooling chip 61 is provided inside the filter cartridge 2. The length of the semiconductor cooling chip 61 is equal to the inner diameter of the filter cartridge 2. The semiconductor cooling chip 61 is electrically connected to the controller 124. A top plate 6 is fixed at the upper end of the semiconductor cooling chip 61. The outer diameter of the top plate 6 is equal to the inner diameter of the filter cartridge 2. The heat dissipation cavity 123, the control cavity 122, the connecting seat 11 and the filter cartridge 2 are provided with a cooling structure 3, and the cooling structure 3 is electrically connected to the controller 124; The cooling structure 3 includes an exchange component 36 and a rotating component. The cooling structure 3 uses the exchange component 36 to cool the gas cooled by the semiconductor cooling chip 61 to the controller 124 in the control cavity 122 and the heat dissipation fins 131 in the heat dissipation cavity 123. The cooling structure 3 rotates the filter cartridge 2 through the rotating component. Two cleaning scrapers 41 are symmetrically fixed between the lower end of the lamp holder 12 and the upper end of the base 1. The two cleaning scrapers 41 are in contact with the outer wall of the filter cartridge 2. The two cleaning scrapers 41 work with the rotating part of the cooling structure 3 to clean the filter cartridge 2.
[0026] In this embodiment, when the temperature sensor detects that the temperature in the heat dissipation cavity 123 or the control cavity 122 reaches the threshold preset by the controller 124, the controller 124 issues a command to start the semiconductor cooling chip 61. After it starts working, it cools the surrounding air and forms a low-temperature gas at its upper end.
[0027] The exchange component 36 in the cooling structure 3 starts to operate, guiding the low-temperature gas cooled by the semiconductor refrigeration chip 61 to the control cavity 122 and the heat dissipation cavity 123 for heat exchange, thereby achieving cooling.
[0028] Specifically, in the control cavity 122, the cryogenic gas cools and dissipates heat from the controller 124 to prevent the controller 124 from malfunctioning or experiencing performance degradation due to excessive temperature; in the heat dissipation cavity 123, the cryogenic gas cools the heat dissipation fins 131 mounted on the lamp body 13. After absorbing the heat generated by the lamp body 13, the heat dissipation fins 131 dissipate the heat through heat exchange with the cryogenic gas, thereby reducing the temperature of the lamp body 13 and ensuring the normal operation of the aviation obstruction light.
[0029] The rotating component in the cooling structure 3 drives the filter cartridge 2 to rotate. During the rotation of the filter cartridge 2, the cleaning scraper 41 cleans the outer wall of the filter cartridge 2, scraping away dust, debris and other impurities attached to the outer wall of the filter cartridge 2, preventing these impurities from clogging the filter cartridge 2 and affecting air circulation and heat dissipation.
[0030] In an optional embodiment, the rotating component of the cooling structure 3 includes a motor 31 mounted on the inner wall of the connecting seat 11. The output end of the motor 31 is fixedly connected to a gear 32. The gear 32 is rotatably mounted on the upper end of the top plate 6. The gear 32 meshes with an internal gear ring 21, which is fixedly mounted on the upper end of the filter cartridge 2.
[0031] It should be noted that motor 31 starts operating after receiving a start command from controller 124. The output of motor 31 drives gear 32, which is fixedly connected to it, to rotate. Since gear 32 is mounted on the top plate 6, and the top plate 6 is connected to the semiconductor cooling chip 61 and its position is relatively fixed, this provides support for the stable rotation of gear 32. At the same time, when gear 32 rotates, it drives the internal gear ring 21, which meshes with it, to rotate. Since the internal gear ring 21 is fixed on the filter cartridge 2, the rotation of the filter cartridge 2 is ultimately achieved.
[0032] When the rotating component drives the filter cartridge 2 to rotate, the cleaning scraper 41 continuously scrapes the outer wall of the filter cartridge 2, effectively removing dust, debris, and other impurities adhering to the outer wall of the filter cartridge 2. This prevents these impurities from clogging the pores of the filter cartridge 2, ensuring that air can flow smoothly through the filter cartridge 2.
[0033] In an optional embodiment, the internal gear ring 21 meshes with a second gear 34, the second gear 34 is rotatably mounted on the upper end of the top plate 6, and the lower middle part of the second gear 34 extends to the lower end of the top plate 6 via a connecting rod and is fixedly connected to an exhaust fan 35, the exhaust fan 35 being located at the cooling end of the semiconductor cooling chip 61.
[0034] It should be noted that when the internal gear ring 21 rotates, the gear 34 meshing with it will also rotate, and the rotation of gear 34 will drive the exhaust fan 35 to rotate as well. The exhaust fan 35 is located at the cooling end of the thermoelectric cooler 61. When the exhaust fan 35 rotates, it can actively draw the low-temperature gas generated after the thermoelectric cooler 61 is cooled into the exchanger 36.
[0035] In an optional embodiment, an air blowing pipe 5 is installed inside the filter cartridge 2. The air blowing pipe 5 has an air inlet at its upper end. There is a gap between the air inlet at the upper end of the air blowing pipe 5 and the lower end of the top plate 6. The lower middle part of the gear 32 extends into the air blowing pipe 5 through a connecting rod and is fixedly connected to the blower fan 33. Several air blowing heads 51 facing the filter holes of the filter cartridge 2 are fixed on the side wall of the air blowing pipe 5.
[0036] It should be noted that when gear 32 rotates, it drives the blower fan 33 to rotate, generating airflow inside the air blower pipe 5. Outside air enters through the air inlet at the top of the air blower pipe 5, and a gap exists between the air inlet and the lower end of the top plate 6, ensuring smooth airflow into the air blower pipe 5. The air entering the air blower pipe 5 is accelerated by the blower fan 33, forming an airflow with a certain pressure and velocity. This airflow is then ejected through several blower heads 51 fixed to the side wall of the air blower pipe 5, facing the filter holes of the filter cartridge 2, achieving directional blowing of air onto the filter holes of the filter cartridge 2.
[0037] The high-speed airflow ejected from the air blower 51 can directly impact the filter holes of the filter cartridge 2, blowing off the dust and debris adhering to the inner wall and surface of the filter holes, preventing the filter holes from becoming clogged, and ensuring that air can flow smoothly through the filter cartridge 2.
[0038] In an optional embodiment, the exchange component 36 includes a first air pipe 361, a second air pipe 362, a third air pipe 363, a fourth air pipe 364, and a fifth air pipe 365. The air inlet end of the first air pipe 361 extends through the top plate 6 into the interior of the filter cartridge 2, and the air inlet end of the first air pipe 361 is located at the cooling end of the semiconductor cooling chip 61. The air outlet end of the first air pipe 361 extends into the heat dissipation cavity 123 and connects to the air inlet end of the second air pipe 362. The air outlet of the second air pipe 362 extends into the control cavity 122 through the third air pipe 363 and is connected to the air inlet of the fourth air pipe 364. The air outlet of the fourth air pipe 364 is connected to the air inlet of the fifth air pipe 365. The air outlet of the fifth air pipe 365 extends through the top plate 6 into the filter cartridge 2. The air outlet of the fifth air pipe 365 is located at the heating end of the semiconductor cooling chip 61.
[0039] It should be noted that the low-temperature gas enters the heat dissipation chamber 123 through air pipe 361, where it exchanges heat with the heat dissipation fins 131, absorbing the heat from the fins and lowering their temperature. The gas then enters the control chamber 122 through air pipes 362 and 363, directly cooling the controller 124 and removing the heat generated during its operation. Next, the gas flows out of the control chamber 122 through air pipes 364 and 365. The outlet of air pipe 365 is located at the heating end of the semiconductor cooling chip 61. The aforementioned blower 33 draws the hot air into the filter cartridge 2, and finally ejects it through the blower head 51.
[0040] Multiple air pipes are used for heat exchange and cooling to prevent external air from directly entering the control cavity 122 and the heat dissipation cavity 123, thereby preventing external air impurities from damaging the components in the control cavity 122 and the heat dissipation cavity 123.
[0041] In an optional embodiment, the trachea 1 361 and trachea 4 364 adopt a planar helical structure.
[0042] It should be noted that the planar spiral structure, in which the gas tube extends in a spiral shape within a plane, helps to increase the flow path and time of the gas within the tube, thereby improving heat exchange efficiency and making the cooling effect more significant.
[0043] In an optional embodiment, a connecting plate 42 is fixed to one end of the cleaning scraper 41 away from the filter cartridge 2. The upper end of the connecting plate 42 is fixedly connected to the lamp holder 12, and the lower end of the connecting plate 42 is fixedly connected to the base 1. A baffle 43 is fixed to the end of the connecting plate 42 away from the cleaning scraper 41, and the connecting plate 42 is perpendicular to the baffle 43.
[0044] It should be noted that the end of the cleaning scraper 41 away from the filter cartridge 2 is fixedly connected to the plate 42. This fixed connection method is usually achieved by mechanical connection means such as welding or bolt connection. The purpose is to form the cleaning scraper 41 and the connecting plate 42 into an integral structure so that they can work together when moving and under force.
[0045] The vertical installation of the connecting plate 42 and the baffle 43 can prevent hot air from directly entering the air inlet on the other side of the filter cartridge 2 when it is discharged, thus avoiding increasing the difficulty and energy consumption of subsequent air cooling treatment, ensuring that the air temperature entering the filter cartridge 2 is relatively low, and reducing operating costs.
[0046] The above embodiment discloses a self-cooling aviation obstruction light, wherein when the temperature sensor detects that the temperature inside the heat dissipation cavity 123 or the control cavity 122 reaches a threshold preset by the controller 124, the controller 124 issues a command to activate the semiconductor cooling chip 61. After the semiconductor cooling chip 61 starts working, it cools the surrounding air and forms a low-temperature gas at its cooling end.
[0047] The controller 124 issues a command to start the motor 31; when the motor 31 is running, it drives the gear 32 to rotate, which in turn drives the internal gear ring 21 to rotate, thus realizing the rotation of the filter cartridge 2; during the rotation of the filter cartridge 2, the cleaning scraper 41 will clean the outer wall of the filter cartridge 2, scraping off the dust, debris and other substances attached to the outer wall of the filter cartridge 2.
[0048] When the internal gear ring 21 rotates, it drives the gear 34 to rotate, thereby causing the exhaust fan 35 to rotate and actively draw the low-temperature gas generated after the semiconductor refrigeration chip 61 is cooled into the exchange component 36.
[0049] Low-temperature gas enters from gas pipe 361 into gas pipe 362 of the heat dissipation chamber 123. Inside the heat dissipation chamber 123, it exchanges heat with the heat dissipation fins 131 mounted on the lamp body 13, absorbing heat from the fins and lowering their temperature, thus reducing the temperature of the lamp body 13. The gas then passes through gas pipes 362 and 363 into gas pipe 364 of the control chamber 122, cooling the controller 124 and removing the heat generated during its operation. Finally, the gas passes through gas pipes 364 and 365 into the heating end of the semiconductor cooling chip 61 in the filter cartridge 2.
[0050] When gear 32 rotates, it drives the blower fan 33 to rotate. Hot air enters from the air inlet at the top of the blower pipe 5. This airflow is ejected through the blower head 51 and directly impacts the filter holes of the filter cartridge 2, blowing off the dust and debris attached to the inner wall and surface of the filter holes, further preventing the filter holes from clogging and ensuring smooth airflow.
[0051] The vertical installation of the connecting plate 42 and the baffle 43 can prevent hot air from directly entering the air inlet on the other side of the filter cartridge 2 when it is discharged, thus avoiding increasing the difficulty and energy consumption of subsequent air cooling treatment, ensuring that the air temperature entering the filter cartridge 2 is relatively low, and reducing operating costs.
[0052] Any aspects of this invention not described in detail are well-known to those skilled in the art.
[0053] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
