Description

Technical Field

[0001] This invention relates primarily to the field of antenna array technology, and in particular to an integrated carbon fiber antenna frame for electro-hydraulic transmission. Background Technology

[0002] Phased array radars offer advantages such as flexible beamforming, controllable pointing, and high redundancy, leading to their increasingly widespread application on various payload platforms across land, sea, air, and space. As the core component of a phased array radar, the antenna array's aperture, cooling method, and level of integration determine the overall electronic and structural performance of the radar system.

[0003] Currently, radar systems face numerous mission requirements, including rapid real-time tracking of high-speed moving targets, longer detection ranges, shorter maintenance times, and lighter system weight. This necessitates radars with larger apertures, higher reliability, greater integration, and lighter weight. Existing phased array antennas are complex in structure, have numerous external components, and suffer from low integration. Using traditional design methods leads to problems such as large antenna array size and heavy weight. This is especially true for airborne and spaceborne radars, where weight has a decisive impact. Therefore, comprehensively utilizing lightweight, high-strength materials and improving integration levels are urgent problems to be solved.

[0004] Cooling of phased array antenna surfaces typically involves natural cooling, forced air cooling, and liquid cooling. Due to the increasing power of radar, liquid cooling is becoming increasingly prevalent. Liquid cooling of the array surface requires providing inlet / outlet cooling channels for each external device, resulting in complex cooling pipe designs and a large assembly workload. Therefore, to address these issues, innovative designs are urgently needed in the top-level architecture layout and cooling pipe design of the array surface to solve these challenges. Summary of the Invention

[0005] To address the issues of heavy weight and complex assembly of existing high-power radar antenna arrays, this invention provides an integrated carbon fiber antenna frame for electro-hydraulic transmission. The traditional metal frame is designed as a composite sandwich structure frame composed of multiple parts, aiming to simplify the installation of external equipment, reduce the weight of the radar system, improve the structural load-bearing capacity, and enhance system integration.

[0006] To achieve the above objectives, the present invention provides an integrated carbon fiber antenna frame for electro-hydraulic transmission, comprising a metal transition block, a flow channel, an embedded part, an upper shell, and a lower shell; The flow channel includes a flow channel body, a liquid cooling connector mounting base, and a liquid cooling connector, with the flow channel body and the liquid cooling connector mounting base bonded together. The metal transition block serves as the physical interface for the installation of external equipment. The external equipment is mounted on the metal transition block, and at the same time, the external equipment is inserted into the liquid cooling connector to form a cooling circuit. The embedded parts provide an external mounting interface for the integrated carbon fiber antenna frame for electro-hydraulic transmission; The upper housing includes an outer shell and an equipotential layer, which are bonded to the outer shell. The flow channel is embedded in the sandwich structure formed by the upper and lower shells, and the metal transition block is connected to the upper shell with a rubber screw.

[0007] Furthermore, the flow channel body is formed by bonding carbon fiber tubes and carbon fiber tees.

[0008] Furthermore, the liquid cooling connector mounting base is machined from engineering plastic PEEK.

[0009] Furthermore, the embedded parts are made of high-strength aluminum alloy and the surface is anodized.

[0010] Furthermore, the upper shell is formed by autoclaving carbon fiber, and the equipotential layer is formed by bonding copper foil to the upper shell.
