Description

Technical Field

[0001] This utility model relates to the field of radar antenna heat dissipation design technology, specifically to a radar antenna with a fan assembly that can be quickly disassembled and assembled. Background Technology

[0002] With the continuous development of radar phased array antennas, the overall heat dissipation and power consumption are significant, placing increasingly higher demands on fan cooling and presenting more and more challenges to fan design. In the structural design of radar antennas, fans are typically placed on the left and right sides, preventing the antenna front end, bracket, and turntable from affecting the assembly of the fan assembly. In existing technologies, the radar antenna front end is usually fixed to a horizontal surface using a bracket and turntable for target search and testing. In certain special cases, it is required that the radar antenna array cannot be removed from the bracket. The conventional fan assembly method involves screws along the fan axis. However, if this conventional method is used, the bracket blocks the bottom of the fan assembly, hindering screw removal and fan assembly removal, failing to meet the requirements for rapid disassembly and assembly, and is time-consuming and labor-intensive. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a radar antenna with a fan assembly that can be quickly disassembled and assembled.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A radar antenna with a fan assembly that can be quickly disassembled and assembled includes an antenna array, a bracket, and a turntable. A heat dissipation assembly is provided inside the antenna array and is located at the bottom of the antenna array where it connects to the bracket. A power line is provided inside the antenna array and is connected to the heat dissipation assembly. A first cover plate and a second cover plate are rotatably arranged on both sides of the bottom of the antenna array. The first cover plate and the second cover plate are provided with fastening screws that pass through the cover plates and the heat dissipation assembly, thereby locking the cover plates and the heat dissipation assembly onto the outer shell of the antenna array.

[0006] The power cord uses an aviation plug design.

[0007] Both the first and second cover plates are curved.

[0008] The fastening screws are hand-tightening screws. The first and second cover plates have screw holes and are equipped with matching hand-tightening screws. The screw seat of the hand-tightening screw is a Torx triangular screw seat. The screw seat grooves of the first and second cover plates are opened to accommodate the Torx triangular screw seats.

[0009] The heat dissipation component adopts a fan assembly heat dissipation mode. There is a ventilation grille on the bottom shell of the antenna array corresponding to the working fan of the fan assembly, and the fan assembly is equipped with a handle.

[0010] The beneficial effects of this utility model are:

[0011] This utility model adopts a bottom-side pull-out fan assembly structure, which, together with an arc-shaped cover plate and self-made hand-tightening screws, allows the fan assembly to be quickly pulled out from the side without removing the radar antenna array from the bracket, thus enabling convenient and quick disassembly and assembly of the fan assembly.

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] See Figure 1-5 This utility model provides a technical solution:

[0020] A radar antenna with a fan assembly that allows for quick assembly and disassembly is disclosed. The radar antenna consists of an antenna array 1, a support 2, and a turntable 3. A fan assembly 7 is located inside the antenna array 1, at the bottom where it connects to the support 2. An aviation connector 6 is located inside the antenna array 1, connecting the fan assembly 7 to a power source within the antenna array 1. A first cover plate 4 and a second cover plate 5 are rotatably mounted on both sides of the bottom of the antenna array 1. Both the first cover plate 4 and the second cover plate 5 are arc-shaped to conform to the external shape of the antenna array. The first cover plate 4 has screw holes 41 and is equipped with matching first hand-tightening screws 8. The screw seat of the first hand-tightening screw 8 is a triangular screw seat. A screw seat groove 42 is provided on the first cover plate 4 to accommodate the triangular screw seat. The first hand-tightening screw 8 passes through the rotatable arc-shaped first cover plate 4 and the fan assembly 7, simultaneously locking the first cover plate 4 and the fan assembly 7 onto the outer shell of the antenna array 1. The second cover plate 5 also has screw holes 41 and is equipped with a matching second hand-tightening screw 9. The second screw is set in the same way as the first screw. A ventilation grille 10 is provided on the bottom outer shell of the antenna array 1 at the working fan of the fan assembly 7. In order to make full use of space, a ventilation grille 10 can also be provided on the second cover plate 5.

[0021] To facilitate the removal of the fan assembly 7, a handle 71 is provided on the fan assembly 7.

[0022] In this embodiment, the heat dissipation component uses a fan assembly 7, but heat pipes or other heat dissipation methods can also be used.

[0023] When the fan assembly 7 malfunctions and needs replacement, unscrew the thumbscrews on both sides of the bottom of the antenna array 1, open the arc-shaped covers on both sides of the bottom, disconnect the connection between the aviation plug 6 and the fan assembly 7, pull the handle 71 to remove the fan assembly 7 from inside the antenna array 1, and install the new fan assembly 7 in its original position. The use of the aviation plug 6 connection method ensures the waterproof performance of the radar antenna.

[0024] The fan assembly provided by this utility model is a radar antenna that can be quickly disassembled and assembled. It adopts a side-pull-out fan assembly 7 assembly structure, which allows the fan assembly 7 to be replaced without removing the antenna array 1 from the bracket 2.
