Description

Technical Field

[0001] This utility model relates to the field of aviation obstruction light technology, and more specifically, it relates to an aluminum alloy heat dissipation cover plate for a type A medium-intensity aviation obstruction light. Background Technology

[0002] Aviation obstruction lights are special lighting fixtures used to identify obstacles and provide safety warnings to aircraft, preventing collisions. Type A medium-intensity aviation obstruction lights, as an important type, are typically installed on tall buildings, towers, chimneys, and other structures. They emit light signals of specified intensity and color at night or in low visibility conditions. During operation, the internal electronic components of Type A medium-intensity aviation obstruction lights generate a significant amount of heat. If this heat cannot be dissipated in time, the internal temperature of the light body will rise, affecting not only the luminous efficiency and stability of the light source but also shortening the lifespan of electronic components. In severe cases, it can even cause malfunctions, affecting the normal operation of the aviation obstruction light and posing a threat to aircraft flight safety. The heat dissipation cover is an important component of the heat dissipation system of Type A medium-intensity aviation obstruction lights; its main function is to conduct heat from inside the light body and dissipate it into the surrounding environment. Currently, existing aluminum alloy heat dissipation covers for Type A medium-intensity aviation obstruction lights typically employ a simple flat plate structure with heat dissipation fins. The arrangement of the heat dissipation fins is relatively simple, resulting in a limited heat dissipation area. Furthermore, the airflow between the heat dissipation fins is not smooth enough, leading to low heat dissipation efficiency. This makes it difficult to meet the heat dissipation requirements of aviation obstruction lights operating at high power for extended periods. Therefore, it is necessary to improve the existing aluminum alloy heat dissipation covers for Type A medium-intensity aviation obstruction lights and design a heat dissipation cover with higher heat dissipation efficiency to improve the operational reliability and service life of aviation obstruction lights. Utility Model Content

[0003] (1) Technical problems to be solved

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an aluminum alloy heat dissipation cover plate for a type A medium-intensity aviation obstruction light, which has the characteristics of high heat dissipation efficiency, can effectively dissipate the heat inside the lamp body, and ensure the normal operation of the aviation obstruction light.

[0005] (2) Technical solution

[0006] To achieve the above objectives, this utility model provides an aluminum alloy heat dissipation cover for a type A medium-intensity aviation obstruction light, including a cover body. The upper surface of the cover body is provided with a plurality of heat dissipation fin groups, and a flow guiding structure is provided on the cover body between the heat dissipation fin groups. The back of the cover body is provided with an installation structure adapted to the aviation obstruction light body.

[0007] When using the aluminum alloy heat dissipation cover plate of the Type A medium-intensity aviation obstruction light using this technical solution, the heat dissipation area is increased by the heat dissipation fin assembly, which is conducive to heat dissipation. At the same time, the heat dissipation fin assembly adopts a staggered arrangement of the first and second heat dissipation fins, and the height of the first heat dissipation fin is greater than the height of the second heat dissipation fin. This staggered structure can break the boundary layer of air flow between the heat dissipation fins, increase air turbulence, and improve heat dissipation efficiency.

[0008] Furthermore, the heat dissipation fin assembly includes a plurality of first heat dissipation fins and a plurality of second heat dissipation fins, wherein the height of the first heat dissipation fins is greater than the height of the second heat dissipation fins, and the first heat dissipation fins and the second heat dissipation fins are arranged alternately.

[0009] Furthermore, both the first and second heat dissipation fins are arranged perpendicular to the upper surface of the cover plate body, and the distance between two adjacent first heat dissipation fins is 10-15mm, and the distance between two adjacent second heat dissipation fins is 8-12mm.

[0010] Furthermore, the flow guiding structure includes several flow guiding grooves, which are arranged along the length of the cover plate body, and the depth of the flow guiding grooves is 3-5mm and the width is 8-12mm.

[0011] Furthermore, the mounting structure includes a plurality of mounting holes and positioning protrusions. The mounting holes are evenly distributed on the edge of the back side of the cover plate body, and the positioning protrusions are located in the central area of ​​the back side of the cover plate body.

[0012] Furthermore, the cover plate body is integrally formed from 6061 aluminum alloy.

[0013] Furthermore, the upper surface of the heat dissipation fin assembly is provided with a rounded corner transition structure, and the edge of the cover plate body is provided with an upward flange with a flange height of 5-8mm.

[0014] (3) Beneficial effects

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. The aluminum alloy heat dissipation cover of the Type A medium-intensity aviation obstruction light is equipped with heat dissipation fins, which increases the heat dissipation area and facilitates heat dissipation. At the same time, the heat dissipation fins adopt an alternating arrangement of the first and second heat dissipation fins, and the height of the first heat dissipation fins is greater than that of the second heat dissipation fins. This alternating structure can break the boundary layer of air flow between the heat dissipation fins, increase air turbulence, and improve heat dissipation efficiency.

[0017] 2. The aluminum alloy heat dissipation cover of the Type A medium-intensity aviation obstruction light features a flow guiding structure. The structure is located between the heat dissipation fins on the cover body. The flow guiding grooves guide the air, allowing it to flow more smoothly between the heat dissipation fins and carry away heat in time, thus further improving the heat dissipation effect.

Obviously, the specific embodiments described are only a part of the embodiments of this utility model, and not all of them.

[0024] Example:

[0025] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below.

[0026] Please see Figure 1-2 This utility model provides a technical solution: an aluminum alloy heat dissipation cover plate for a type A medium-intensity aviation obstruction light, including a cover plate body 1, a plurality of heat dissipation fin groups 2 on the upper surface of the cover plate body 1, a flow guiding structure 3 located between the heat dissipation fin groups 2 on the cover plate body 1, and an installation structure 4 adapted to the aviation obstruction light body on the back of the cover plate body 1.

[0027] Specifically, the heat dissipation fin group 2 includes a plurality of first heat dissipation fins 21 and a plurality of second heat dissipation fins 22. The height of the first heat dissipation fins 21 is greater than the height of the second heat dissipation fins 22, and the first heat dissipation fins 21 and the second heat dissipation fins 22 are arranged alternately.

[0028] By adopting the above technical solution, the heat dissipation fin group 2 is set up, which increases the heat dissipation area and facilitates heat dissipation. At the same time, the heat dissipation fin group 2 adopts a staggered arrangement of the first heat dissipation fin 21 and the second heat dissipation fin 22, and the height of the first heat dissipation fin 21 is greater than the height of the second heat dissipation fin 22. This staggered structure can break the boundary layer of air flow between the heat dissipation fins, increase air turbulence, and improve heat dissipation efficiency.

[0029] Specifically, the first heat dissipation fin 21 and the second heat dissipation fin 22 are both arranged perpendicular to the upper surface of the cover plate body 1, and the distance between two adjacent first heat dissipation fins 21 is 10-15mm, and the distance between two adjacent second heat dissipation fins 22 is 8-12mm.

[0030] Specifically, the flow guiding structure 3 includes several flow guiding grooves 31, which are arranged along the length of the cover plate body 1, and the depth of the flow guiding grooves 31 is 3-5mm and the width is 8-12mm.

[0031] By adopting the above technical solution, and by setting the airflow guiding structure 3, the cover plate body 1 is provided with the airflow guiding structure 3 between the heat dissipation fin group 2. The airflow guiding groove 31 can guide the air, so that the air can flow more smoothly between the heat dissipation fins, and carry away the heat in time, thereby further improving the heat dissipation effect.

[0032] Specifically, the mounting structure 4 includes several mounting holes 41 and positioning protrusions 42. The mounting holes 41 are evenly distributed on the edge of the back of the cover plate body 1, and the positioning protrusions 42 are located in the central area of ​​the back of the cover plate body 1.

[0033] By adopting the above technical solution, the mounting structure 4 includes a mounting hole 41 and a positioning protrusion 42. The positioning protrusion 42 facilitates the positioning and installation of the cover plate and the lamp body. The mounting hole 41 is used to fix the cover plate to the lamp body with fasteners, ensuring a tight connection between the cover plate and the lamp body, which is beneficial for heat conduction.

[0034] Specifically, the cover plate body 1 is made of 6061 aluminum alloy in one piece.

[0035] By adopting the above technical solution, the cover plate body 1 is integrally formed from 6061 aluminum alloy. 6061 aluminum alloy has good thermal conductivity and mechanical properties, which can quickly conduct the heat inside the lamp body to the heat dissipation fins, and the integrally formed structure ensures the structural strength and heat dissipation performance stability of the cover plate.

[0036] Specifically, the upper surface of the heat dissipation fin assembly 2 is provided with a rounded corner transition structure 23, and the edge of the cover plate body 1 is provided with an upward flange 5, the height of which is 5-8mm.

[0037] By adopting the above technical solution, the upper surface of the heat dissipation fin assembly 2 is provided with a rounded corner transition structure 23, which can reduce the resistance during air flow and make the air flow smoother. At the same time, it can also prevent the heat dissipation fins from being damaged during transportation and installation. The edge of the cover plate body 1 is provided with an upward flange 5. The flange 5 can strengthen the cover plate body 1, improve the overall structural strength of the cover plate, and at the same time, it can also block external debris from entering between the heat dissipation fins to a certain extent, thus ensuring the heat dissipation effect.

[0038] The working principle of this utility model is as follows:

[0039] In use, the cover plate body 1 is first positioned with the lamp body of the Type A medium-intensity aviation obstruction light by the positioning protrusion 42. Then, the cover plate body 1 is fixed to the lamp body by fasteners through the mounting holes 41. The heat generated inside the lamp body is conducted to the heat dissipation fin group 2 through the cover plate body 1. Under the action of natural wind or other airflow, the air flows through the heat dissipation fin group 2 under the guidance of the guide groove 31. Since the first heat dissipation fin 21 and the second heat dissipation fin 22 are arranged alternately, the air flow generates disturbance, which can make more full contact with the heat dissipation fins and carry away the heat, thus achieving efficient heat dissipation.

[0040] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
