[0003] In traditional antenna arrays, the signal processing module, power supply module, transceiver module, receiver module, and feed module are relatively dispersed and installed on the array frame. This results in insufficient integration of various modules and makes centralized heat dissipation difficult. Summary of the Invention

[0018] The embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. In the description of the present invention, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.

[0019] Please see Figure 1-9 The present invention provides an embodiment of a two-dimensional phased array radar array for X-band, comprising an array frame 1, an electronic control component 3 on one side of the array frame 1, and a connecting component 2 on the other side of the array frame 1; the electronic control component 3 includes an integrated board 30, on which a module component 32 is integrated; the connecting component 2 includes a sealing plate 21, on the side of the sealing plate 21 facing the array frame 1, a connector 20 is provided, and on the other side of the sealing plate 21, an integrated frame 25 for integrating umbrella-shaped elements 24 is provided, and the sealing plate 21 and the integrated frame 25 are sealed on the other side of the array frame 1 by an antenna cover 23; the array frame 1 also has a connecting hole 10, and a fan 12 installed in the connecting hole 10 provides forced cooling to the inside of the array frame 1.

[0020] In summary, the integrated board 30 integrates all modules, and then uses the array frame 1 to separate the electronic control component 3 and the connecting component 2, so that both the electronic control component 3 and the connecting component 2 have their own heat dissipation space, and the fan 12 is used for forced air cooling. This achieves both a high degree of integration and facilitates centralized heat dissipation. For example, Figure 4As shown, module component 32 includes signal processing module 39, power supply module 311, transceiver module 312, and receiving module 310; the cover plate 21 is welded to the array frame 1 by vacuum brazing; the radome 23 is made of non-metallic material to avoid affecting signal transmission and reception; the array frame 1 is integrally processed from thick aluminum plate.

[0021] To enable the device to operate in all weather conditions, the connection between the integrated board 30 and the array frame 1 is sealed using a first sealing ring 33; a second sealing ring 22 is also provided between the radome 23 and the facing surfaces of the array frame 1. Therefore, two sealing rings can be used to seal both ends of the array frame 1, improving the device's waterproof and dustproof capabilities, thereby enhancing its all-weather application capability.

[0022] Based on the above solution, a separate heat dissipation cavity can meet the equipment's heat dissipation needs while preventing moisture from contacting electrical equipment, thus avoiding corrosion, short circuits, and equipment failure. This reliable waterproof performance allows the radar array to operate under various climate and weather conditions.

[0023] To facilitate user maintenance of the electronic control component 3, the bottom of the integrated board 30 is hinged to the array frame 1 via a hinge 38. Therefore, when the module component 32 is damaged, the integrated board 30 can be flipped open to expose the module component 32 and the power supply component 35 to the maintenance personnel.

[0024] To facilitate rapid heat dissipation, the integrated frame 25 is also provided with through holes 26, thus increasing the contact area between the integrated frame 25 and the airflow, facilitating heat exchange and air flow. Simultaneously, the side of the array frame 1 facing the sealing plate 21 is also provided with heat dissipation columns 13. Therefore, while centrally fixing the umbrella-shaped array 24, the through holes 26 and heat dissipation columns 13 can also increase the contact area between the integrated frame 25 and the array frame 1 and the airflow, allowing the fan 12 to dissipate heat. The through holes 26 can be rectangular or circular, or a combination of rectangular and circular shapes distributed on the integrated frame 25.

[0025] Based on the above solution, since the other side of the integrated board 30 is provided with an air duct 37, the hot airflow inside the electronic control component 3 can exchange heat smoothly. Furthermore, the air duct 37 is also provided with heat dissipation fins 36, and the integrated board 30 is designed with heat dissipation fins 36 to increase the heat dissipation effect. Cool air enters through the bottom air inlet, and the fan 12 at the top of the array frame 1 draws air from the inside and exhausts it to the outside, thereby removing internal heat. At the same time, the air duct 37 is covered by a cover plate 31, making the air duct 37 relatively sealed, thus making the airflow direction more stable.

[0026] Furthermore, since the electronic control component 3 also includes a power supply component 35 installed within the array frame 1, and the module component 32 is isolated from the power supply component 35 by a partition 34, the partition 34 can further expand the airflow contact area to improve heat dissipation while avoiding mutual interference between the module component 32 and the power supply component 35. Additionally, an umbrella-shaped array 24 is installed on the other side of the sealing plate 21, and the umbrella-shaped array 24 is connected to the power supply component 35 via a connector 20. This connection method completes the device connection while ensuring a waterproof seal; the connector 20 is preferably a KK connector. The sealing plate 21 is vacuum brazed onto the array frame 1, therefore the sealing plate 21 is not removable. Sufficient thickness is reserved at the location where the connector 20 is installed to facilitate subsequent installation. The mounting holes for the connector 20 are machined after the sealing plate 21 is vacuum brazed.

[0027] The upper surface of the array frame 1 is also equipped with a main antenna 4 and an auxiliary antenna 5 to enhance the signal acquisition capability of the device. The array frame 1 is movably connected to the auxiliary antenna 5 via mounting holes 11. Both the main antenna 4 and the auxiliary antenna 5 are Beidou antennas. When the auxiliary antenna 5 is removed, the lifting eye screws can be connected to the mounting holes 11 for easy hoisting of the array frame 1. The mounting holes 11 are preferably threaded holes. Therefore, sharing the same set of mounting holes 11 with the lifting eye screws eliminates any extra empty threaded holes on the outside of the array during use. This design increases both the corrosion resistance and aesthetics of the array. For example, when the equipment needs to be transported and hoisted, the mounting holes 11 on the top of the array frame 1 for the main antenna 4 also serve as mounting holes for the M10 lifting eye screws. During hoisting, the top main antenna 4 is first unscrewed, and the lifting eye screws are installed for hoisting. After hoisting, the lifting eye screws are unscrewed again, and the main antenna 4 is installed.

[0028] Furthermore, since the bottom surface of the array frame 1 is provided with a lower support ear 15, and the side of the array frame 1 facing the electronic control component 1 is also provided with an upper support ear 14; specifically, there are two lower support ears 15, and the upper support ear 14 is located between the two lower support ears 15, so the array frame 3 can be installed and fixed using three support ears; in addition, in order to prevent foreign objects from entering the device, the fan 12 is covered in the connection hole 10 by the provided dust cover 16.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
