Description

Technical Field

[0001] This invention relates to the field of airborne radar equipment technology, and in particular to an airborne radar structure that can be fitted with thermally conductive materials. Background Technology

[0002] Airborne radar structure is a crucial component supporting antennas and electronic equipment, and advanced structural design is vital to its performance. In the field of airborne radar, integrated structural design is a significant trend. Structural integration implies high functional integration and low weight, which is of great practical significance for meeting radar performance requirements. With the increasing diversity of radar targets and the expansion of detection ranges, the power of airborne radars is growing. Traditional heat dissipation methods place a heavy burden on the radar's weight. Therefore, exploring integrated design of heat dissipation and load-bearing structure for airborne radar is of great importance to integrated radar design.

[0003] Traditional airborne radar structures are typically manufactured using material removal methods, which limit design freedom and integration due to manufacturing constraints. Additive manufacturing, on the other hand, has flourished since the beginning of this century, playing a vital role in various fields. It demonstrates advantages such as the ability to form complex structural parts, porous structures, hollow structures, and integrated parts. Utilizing the advantages of additive manufacturing for innovative design facilitates better integration.

[0004] In summary, existing airborne radars suffer from problems such as insufficient integration, redundant radar structure, and inadequate heat dissipation. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an airborne radar structure that can be fitted with thermally conductive materials, addressing the shortcomings of the prior art.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: an airborne radar structure that can be equipped with thermally conductive materials, comprising: an integrated main structure, a thermally conductive material mounting structure, a thermally conductive material, and a backplate, wherein an antenna backplate is provided on the top of the integrated main structure, the thermally conductive material mounting structure is installed in the middle of the integrated main structure, the thermally conductive material is installed on the thermally conductive material mounting structure, the thermally conductive material abuts against the antenna backplate, and the backplate is installed at the bottom of the integrated main structure.

[0007] The beneficial effects of adopting the technical solution of this invention are that the integrated main structure integrates load-bearing and heat dissipation functions. Thermally conductive materials are used to reduce the temperature difference of the antenna backplane, increasing its thermal conductivity and temperature uniformity. This enhances the integration and heat dissipation capabilities of the airborne radar. The integrated main structure is integrally molded, reducing connecting bolts, flanges, etc., achieving a lightweight radar structure; the integrated main structure can form hollow air ducts and cable passages, integrating load-bearing, heat dissipation, and sealing functions, achieving an effective combination of heat dissipation and load-bearing functions.

The back plate is installed at the bottom of the partition, and a downdraft is provided below the back plate.

[0009] The beneficial effects of adopting the above-mentioned further technical solution are that two air ducts are used for heat dissipation of the antenna and internal components.

This enhances the radar structure's ability to withstand short-term high-temperature shocks. The thermally conductive material mounting structure passes through the heat dissipation teeth and cable holes in the hollow air duct of the integrated main structure via through-holes, and can move up and down along the direction of the heat dissipation teeth. After the thermally conductive material mounting structure moves to the bottom, the thermally conductive material can be placed into the mounting slot, and then the thermally conductive material mounting structure can be fastened.

The thermally conductive material is fixed by tightening it with the studs on the thermally conductive material mounting structure. The studs on the thermally conductive material mounting structure reach the upper part of the antenna backplate through through holes in the integrated main structure, and are tightened by the sealing gasket and nut-waist assembly, achieving adhesion and sealing between the thermally conductive material and the antenna backplate.

The mounting components include a sealing gasket 4 and a nut and gasket assembly 7.

[0085] The airborne radar structure of the present invention has two air ducts, an upper air duct and a lower air duct. The upper air duct is located in the middle of the antenna back plate of the integrated main structure 1. It is a hollow air duct with mounting surfaces on the upper and lower sides for mounting the radar antenna and electronic assembly. The lower air duct is located below the structural frame of the integrated main structure 1.

[0086] The hollow air duct of the antenna back plate of the integrated main structure 1 is equipped with heat dissipation teeth (first heat dissipation teeth) and wire passage holes, which together play the role of heat dissipation and load bearing. The 3D printed wire passage holes are also beneficial to the internal sealing of the radar structure.

[0087] The thermally conductive material mounting structure 2 and the integrated main structure 1 are integrally formed by 3D printing. The installation of thermally conductive material 3 can reduce the temperature difference of the antenna back plate and improve the temperature uniformity.

[0088] The backplate 6 is provided with heat dissipation fins, which together with the air duct below the integrated main body structure 1 form a heat dissipation structure for the internal electronic assembly to dissipate heat.

[0089] Connector 10 is mounted on backplane 6 for transmitting radar current and signals.

[0090] The beneficial effects of this invention are as follows: The integrated main structure 1 is formed by 3D printing, reducing connecting bolts, flanges, etc., thus achieving a lightweight radar structure; the integrated main structure 1 can form a hollow air duct and cable passage, integrating load-bearing, heat dissipation, and sealing functions, achieving an effective combination of heat dissipation and load-bearing functions; the heat-conducting material mounting structure 2 and the integrated main structure 1 are integrally formed by 3D printing, with heat-conducting material 3 installed inside, effectively improving the structure's temperature uniformity and achieving the heat dissipation target that traditional heat dissipation fins and traditional processing techniques cannot achieve; the upper and lower air duct design of this invention simultaneously meets the heat dissipation needs of the antenna array and electronic assembly, without any other redundant heat dissipation design, achieving a highly integrated integrated design; under the framework of this invention, radar assembly or maintenance only requires opening the antenna cover 5 or the back plate 6, effectively enhancing the overall assemblability and maintainability.

[0091] Based on the above technical solution, the present invention can be further improved as follows: Furthermore, the hollow air duct and back panel 6 of the integrated main structure 1 can be designed with heat dissipation teeth according to the direction of the incoming air and the heat source.

[0092] The beneficial effect of adopting the above-mentioned further scheme is that the heat dissipation tooth arrangement is designed according to the specific working conditions to maximize the heat dissipation capacity of the radar structure.

[0093] Furthermore, the antenna backplate of the integrated main structure 1 can be formed into a hollow cavity (cavity) through additive manufacturing to house the phase change material, and then sealed by welding.

[0094] The beneficial effect of adopting the above-mentioned further solutions is that it can enhance the radar structure's ability to withstand short-term high-temperature shocks.

[0095] Furthermore, the load-bearing structure of the integrated main structure 1 uses an internal lattice structure.

[0096] The beneficial effects of adopting the above-mentioned further solutions are: reducing the structural weight of airborne radar, improving its lightweight nature, and allowing for the design of mechanical properties such as specific stiffness, specific strength, and elasticity of the radar structure.

[0097] Furthermore, the heat dissipation teeth (first heat dissipation teeth) of the hollow air duct in the integrated main structure 1 can be designed as a vibration-resistant structure.

[0098] The beneficial effect of adopting the above-mentioned further solutions is that, while ensuring the heat dissipation capacity of the radar structure, the radar's vibration resistance is improved.

[0099] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
