Description

Technical Field

[0001] This invention relates to the field of phased array antenna technology, and more particularly to a conformal phased array data link system. Background Technology

[0002] Active phased array antennas are increasingly used in military and civilian applications, with hundreds or even thousands of T / R modules distributed across a single antenna array. In missile-borne environments, these modules are arranged compactly with little space for heat dissipation and high system integration coupling, resulting in a very high heat flux density on the antenna array. If this heat cannot be dissipated from the antenna array in time, it will cause the antenna array temperature to rise, leading to a decrease in the performance of the T / R modules or even their failure, thereby affecting the antenna's electrical performance.

[0003] Active liquid cooling utilizes forced convection heat transfer between the liquid within the cooling device's cavity and the surrounding environment. A continuous supply of liquid dissipates the heat generated by the heat source, thereby cooling heat-generating components. The heat transfer coefficient of the liquid cooling medium is more than 20 times that of air; therefore, forced liquid cooling is typically used in applications with high heat flux. The advantages of forced liquid cooling include more uniform heat dissipation and high heat dissipation efficiency.

[0004] The constraints of irregularly shaped and confined space for missile-borne conformal data links, the requirement for phased array antenna element spacing to conform to half-wavelength design, and the need to increase the number of transmit and receive channels by 2 to 4 times under severely limited space conditions have drastically increased the difficulty of spatial layout design, high-integration dense connection, and high-power heat dissipation. The structural design of phased array antennas must simultaneously meet requirements for structural strength, rigidity, heat dissipation, connection reliability, and maintainability. Summary of the Invention

Detailed Implementation

[0050] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0051] Example 1

[0052] A specific embodiment of the present invention discloses a conformal phased array data link system, such as... Figures 1-2 As shown, the system includes an antenna radiating element 1, an RF coaxial connector 2, a TR assembly 3, an upper mounting plate 4, an antenna feed bracket 5, a beam control module 6, a feed network 7, a secondary power supply 8, a frequency source 9, and a signal acquisition and processing module 10. The upper mounting plate 4 provides the docking interface for the missile-borne components. The upper mounting plate 4, the antenna feed bracket 5, and the signal acquisition and processing module 10 form the load-bearing structure of the conformal phased array data link system, providing mounting support for the antenna radiating element 1, the TR assembly 3, the beam control module 6, the feed network 7, the secondary power supply 8, and the frequency source 9.

[0053] The antenna radiating unit 1, RF coaxial connector 2, TR component 3, beam control module 6, feed network 7, secondary power supply 8, frequency source 9, and signal acquisition and processing module 10 are all common terms in the art and are existing devices. Specifically, the antenna radiating unit 1 is used to realize the functions of signal reception and transmission. The RF coaxial connector 2 is used to realize high-power signal transmission; the TR component 3, antenna, and signal acquisition and processing module 10 form a wireless transceiver system; the beam control module 6 generates the control code and working timing of the TR component 3 in real time according to the signals and control commands issued by the signal acquisition and processing module 10; the feed network 7 is used to realize signal power division and synthesis; the frequency source 9 is used to realize the reference clock and sampling clock signals; and the signal acquisition and processing module 10 is used to realize signal storage, processing, and calculation.

[0054] In one specific embodiment of the present invention, the antenna radiating element 1 and the TR component 3 are respectively disposed on both sides of the upper mounting plate 4. An RF coaxial connector 2 passes through the upper mounting plate 4 to connect the TR component 3 and the antenna radiating element 1, establishing a complete signal transmission channel.

[0055] Specifically, the antenna radiating unit 1 and the TR assembly 3 are located on the upper and lower sides of the upper mounting plate, respectively, and are connected by an RF coaxial connector 2. That is, the antenna radiating unit 1 is disposed on the upper surface of the upper mounting plate 4, and the TR assembly 3 is disposed on the lower surface of the upper mounting plate 4. The RF coaxial connector 2 passes through the upper mounting plate 4 to connect the antenna radiating unit 1 and the TR assembly 3. Data communication transmission between the antenna radiating unit 1 and the TR assembly 3 is achieved through the RF coaxial connector 2.

[0056] The upper mounting plate 4 has through holes, and the RF coaxial connector 2 is installed in the through holes, allowing the RF coaxial connector 2 to pass through the upper mounting plate 4 and connect the antenna radiating unit 1 and the TR assembly 3. During the installation of the entire unit, the TR assembly 3 is installed below the upper mounting plate 4 in a bottom-to-top order. Then, the RF coaxial connector 2 is inserted into each through hole. The antenna radiating unit 1 is installed above the upper mounting plate 4, and the upper mounting plate 4 is then installed on the antenna feed bracket 5, thus establishing the signal transmission channel.

[0057] Furthermore, the wave control module 6, the power supply network 7, the secondary power supply 8, the frequency source 9, and the signal acquisition and processing module 10 are connected via radio frequency or low frequency cables.

[0058] In one specific embodiment of the present invention, such as Figures 1-3 As shown, the antenna feeder bracket 5 has an arc-shaped structure. Specifically, the antenna feeder bracket 5 has multiple mounting surfaces, and the angle between adjacent mounting surfaces is an obtuse angle, that is, the angle between adjacent mounting surfaces is 90° to 180°.

[0059] Furthermore, multiple TR components 3 are installed on multiple mounting surfaces of the antenna feeder bracket 5.

[0060] Furthermore, both the upper mounting plate 4 and the antenna feeder bracket 5 are arc-shaped structures, with the upper mounting plate 4 disposed on the upper surface of the antenna feeder bracket 5. The upper mounting plate 4 has mounting surfaces corresponding to multiple mounting surfaces on the antenna feeder bracket 5.

[0061] Furthermore, the upper mounting plate 4 has multiple mounting surfaces of the same size, and an antenna is mounted on each mounting surface. These multiple antennas constitute the antenna radiating element 1, such as... Figure 3 As shown. Correspondingly, the number of RF coaxial connectors 2 and TR components 3 is the same as the number of antennas, with each RF coaxial connector 2 connecting one antenna and one TR component 3.

[0062] For example, the upper mounting plate 4 has four mounting surfaces, and the antenna radiating element 1 consists of four identical antennas, located on the four different mounting surfaces of the upper mounting plate 4. Because there is a certain angle between the mounting surfaces, the antenna radiating element 1, composed of four antennas, can cover an arcuate area, enabling scanning of the complete range required by the technical specifications.

[0063] Furthermore, when the angle between adjacent mounting surfaces is n° and the number of mounting surfaces is 360° / (180°-n°), the multiple mounting surfaces of the upper mounting plate 4 form a closed-loop structure, and the radiation range of the antenna radiation element 1 can cover 360°.

[0064] For example, when the angle between adjacent mounting surfaces is 120° and the number of mounting surfaces is 6, the multiple mounting surfaces of the antenna feed bracket 5 form a closed-loop structure, and the radiation range of the antenna radiation unit 1 can cover 360°.

[0065] In one specific embodiment of the present invention, such as Figures 4-6 As shown, the TR component 3 is provided with eight antenna transceiver interfaces 301, a first power supply interface 302, a first radio frequency interface 303, and a first positioning pin 304.

[0066] The first radio frequency interface 303 communicates with the feed network 7 via a cable; the first power supply interface 302 is connected to the beam control module 6 via a cable. Correspondingly, the TR component 3 is divided into four modules, each fixed to one of the four mounting surfaces of the antenna feed bracket 5; as shown... Figure 6 As shown, each TR component 3 is positioned on the antenna support 5 by two first positioning pins 304.

[0067] Furthermore, the upper mounting plate 4 and the antenna support 5 are positioned by two second positioning pins 501.

[0068] like Figure 8 As shown, the TR component 3 is symmetrically distributed on the antenna feed bracket 5, that is, the power supply interface 302 is all facing the symmetrical center line of the antenna feed bracket 5, and the antenna feed bracket 5 has a first cable hole 502 and a second cable hole 503 symmetrically arranged to facilitate the passage of the radio frequency cable and power supply cable connecting the TR component 3 and the wave control module 6.

[0069] In one specific embodiment of the present invention, the power supply network 7 and the wave control module 6 are connected as a whole, and four first shock absorbers are installed on the wave control module 6. The wave control module 6 is fixedly installed below the antenna feed bracket 5 through the shock absorbers.

[0070] Furthermore, such as Figure 7As shown, the wave control module 6 includes: a wave control PCB board 401, a wave control bracket 402, and a wave control damper 403. The first damper is the wave control damper 403.

[0071] The wave control PCB board 401 is fixedly mounted on the wave control bracket 402. Four wave control dampers 403 are installed on the four corners of the wave control bracket 402. The wave control bracket 402 is connected to the antenna feeder bracket 5 through the wave control dampers 403.

[0072] The wave controller PCB board 401 is equipped with a first power output interface 404, a first power input interface 405, and a control interface 406. Each first power output interface 404 on the wave controller PCB board 401 is connected to four TR components 3. The first power output interface 404 is connected to the four TR components 3 via cables. The horizontal position of each first power output interface 404 is located on the symmetrical center line of multiple TR components 3, and the vertical position is between every two groups of TR components 3. This layout ensures that the power supply cables of the TR components 3 have equal lengths, and at the same time, it can utilize the horizontal space on the antenna feeder bracket 5 for wiring design.

[0073] The first power input interface 405 on the wave control module 6 and the second power input interface 802 on the secondary power supply 8 are located on the same side, and the first power input interface 405 and the second power input interface 802 are connected by a cable; the third power input interface 902 of the frequency source 9 and the second power output interface 803 of the secondary power supply 8 are located on the same side. The third power input interface 902 and the second power output interface 803 are connected by a cable.

[0074] The frequency source 9 and the secondary power supply 8 are fixedly installed on the upper surface of the signal acquisition and processing module 10 and arranged side by side, that is, the frequency source 9 and the secondary power supply 8 are arranged one in front of the other on the signal acquisition and processing module 10. The lower part of the frequency source 9 and the secondary power supply 8 is fixedly connected to the signal acquisition and processing module 10, and the signal acquisition and processing module 10 is fixedly connected to the antenna feeder bracket 5 through the second shock absorber.

[0075] In one specific embodiment of the present invention, such as Figure 9 As shown, the signal acquisition and processing module 10 includes: a signal processing PCB board 1001, a signal processing housing 1002, a signal processing shock absorber 1003, and a signal processing cover plate 1004. The second shock absorber is the signal processing shock absorber 1003.

[0076] The signal processing housing 1002 and the signal processing cover 1004 enclose the signal processing PCB board 1001. Specifically, the signal processing cover 1004 is located below the signal processing housing 1002 and is fixedly connected to the signal processing housing 1002 to form a sealed space. The signal processing PCB board 1001 is disposed within the sealed space formed by the signal processing housing 1002 and the signal processing cover 1004.

[0077] Specifically, four signal processing dampers 1003 are provided on the signal processing box 1002 of the signal acquisition and processing module 10; the signal processing box 1002 is connected to the antenna support 5 through the signal processing dampers 1003.

[0078] Furthermore, such as Figure 10-11 As shown, the signal acquisition and processing module 10 is also provided with a third radio frequency interface 1005 connected to the power supply network 7, a second communication interface 1006 connected to the frequency source 9, a third communication interface 1007 connected to the wave control module 6, and a fourth power supply interface 1008 connected to the secondary power supply 8.

[0079] Specifically, the third radio frequency interface 1005 of the signal acquisition and processing module 10 and the second radio frequency interface 701 of the power supply network are located on the same side and connected by a cable to realize the transmission of radio frequency signals.

[0080] The second communication interface 1006 of the signal acquisition and processing module 10 and the first communication interface 901 of the frequency source 9 are located on the same side and connected by a cable to realize the transmission of communication signals.

[0081] The third communication interface 1007 of the signal acquisition and processing module 10 and the control interface 406 of the wave control module 6 are located on the same side and connected by a cable to realize signal transmission between the wave control module 6 and the signal acquisition and processing module 10.

[0082] The fourth power supply interface 1008 of the signal acquisition and processing module 10 is located on the same side as the second power supply interface 801 of the secondary power supply 8 and is connected by a cable to realize power transmission.

[0083] The multiple second radio frequency interfaces 701 on the power supply network 7 are respectively located on the left and right sides of the power supply network 7, and the second radio frequency interfaces 701 are respectively connected to the first radio frequency interface 303 of the corresponding TR component 3.

[0084] Furthermore, since the conformal phased array data link system generates a lot of heat during operation, the temperature rises, and excessively high temperatures can affect the performance of system components. Therefore, it is necessary to cool the component structure.

[0085] In one specific embodiment of the present invention, the conformal phased array data link system is further provided with a cooling structure.

[0086] like Figures 12-13 As shown, the antenna support 5 has multiple parallel flow channels 504 machined inside. These parallel flow channels 504 are parallel to each other and completely cover the contact area between the antenna support 5 and the TR component 3. A first liquid inlet 505 and a first liquid outlet 506 are provided on both sides of the antenna support 5, located on the front and rear end faces of the antenna support 5. The two ends of each parallel flow channel 504 are connected to the first liquid inlet 505 and the first liquid outlet 506, respectively, and are also connected to the inlet and outlet pipes of the active circulation system, forming a complete first active circulation path. The coolant flowing through this first active circulation path is antifreeze, which can effectively remove the heat dissipation generated by the TR component 3 during operation.

[0087] like Figure 14 As shown, the signal acquisition and processing module 10 has flow channels machined on its structural housing, with straight flow channels 1011 evenly distributed across the entire cross-section. Multiple straight flow channels 1011 are arranged side by side on the signal processing housing 1002, and their two ends are respectively connected to the second liquid inlet 1009 and the second liquid outlet 1010.

[0088] Specifically, a second active circulation path is provided on the signal processing housing 1002. The second liquid inlet 1009 and the second liquid outlet 1010 are located on the front and rear end faces of the signal processing housing 1002, respectively, and are connected to the liquid inlet pipe and liquid outlet pipe of the active circulation system, forming the second active circulation path. The coolant flowing through the second active circulation path is antifreeze, which can carry away the heat dissipation generated by the operation of the signal acquisition and processing module 10 and the secondary power supply 8.

[0089] Furthermore, the active circulation system includes: a water pump, cooling pipes, and a coolant storage tank.

[0090] The water pump is used to circulate the coolant in the active circulation system, and the low-temperature coolant is stored in a storage tank. The cooling pipeline includes an inlet pipe, an outlet pipe, a first active circulation path within the antenna feeder bracket 5, and a second active circulation path within the signal acquisition and processing module 10. Coolant, which is antifreeze, flows through the cooling pipeline and can dissipate the heat generated by the TR component 3, the wave control module 6, the power supply network 7, the signal acquisition and processing module 10, and the secondary power supply 8.

[0091] Furthermore, the inlet and outlet pipes are branched pipes, which can simultaneously connect to the first active circulation path and the second active circulation path.

[0092] Specifically, the first active circulation path includes: a parallel flow channel 504, a first liquid inlet 505, and a first liquid outlet 506; the first liquid inlet 505 is connected to the liquid inlet pipe, and the first liquid outlet 505 is connected to the liquid outlet pipe. Multiple parallel flow channels 504 are arranged parallel to each other along the extending direction of the antenna support 5; and both ends of the parallel flow channels 504 are connected to the first liquid inlet 505 and the first liquid outlet 506.

[0093] The second active circulation path includes a second inlet 1009 and a second outlet 1010; the second inlet 1009 is connected to the inlet pipe, and the second outlet 1010 is connected to the outlet pipe. The second active circulation path also includes straight flow channels 1011, with multiple sets of straight flow channels 1011 arranged in parallel; both ends of the straight flow channels 1011 are connected to the second inlet 1009 and the second outlet 1010, respectively.

[0094] Furthermore, the mounting gap between the TR component 3, the upper mounting plate 4, and the antenna feeder bracket 5 is filled with thermally conductive silicone grease. The thermally conductive silicone grease has good thermal conductivity, enabling heat conduction between components and facilitating rapid heat dissipation.

[0095] Example 2

[0096] In one specific embodiment of the present invention, the second active loop path on the signal acquisition and processing module 10 is improved based on embodiment 1.

[0097] Considering that multiple straight flow channels 1011 on the signal acquisition and processing module 10 are parallel to each other, when coolant flows through the channels, the liquid will preferentially flow in the straight flow channel 1011 aligned with the second inlet 1009 and the second outlet 1010. This is not conducive to the distribution of coolant to the straight flow channels 1011 on both sides, resulting in a faster flow velocity of coolant in the middle straight flow channel 1011 and a slower flow velocity in the straight flow channels 1011 on both sides. In some cases, there may even be no coolant flowing in the outermost straight flow channel 1011. When cooling the signal acquisition and processing module 10, the actual flow area of ​​the coolant is smaller than the arrangement area of ​​the coolant flow channels, which affects the effective implementation of liquid cooling.

[0098] Therefore, as Figure 15 As shown, in one specific embodiment of the present invention, multiple sets of inclined flow channels 1012 are arranged between adjacent straight flow channels 1011. The inclined flow channels 1012 are connected to the straight flow channels 1011 on both sides. The inclined flow channels 1012 serve as multiple branch paths of the straight flow channels 1011, enabling the coolant to flow in the multiple straight flow channels 1011, increasing the heat exchange area between the coolant and the signal acquisition and processing module 10, improving the heat exchange efficiency, and achieving rapid cooling.

[0099] Example 3

[0100] In one specific embodiment of the present invention, the second active loop path on the signal acquisition and processing module 10 is improved based on embodiment 1.

[0101] like Figure 16 As shown, the second active circulation path in this embodiment is a mesh-type flow channel.

[0102] Specifically, a grid-type flow channel network is set between the second liquid inlet 1009 and the second liquid outlet 1010; the flow channel network is connected to the second liquid inlet 1009 and the second liquid outlet 1010; the coolant flows in the flow channel network and exchanges heat with the signal acquisition and processing module 10, thereby realizing liquid cooling heat dissipation for the entire conformal phased array data link system.

[0103] Specifically, the flow channel network includes multiple annular flow channel units 1013, which are spliced ​​together to form the flow channel network.

[0104] Specifically, the flow channel unit 1013 is an annular channel formed by connecting multiple single-sided flow channels 1014, and the multiple flow channel units 1013 are interconnected.

[0105] For example, such as Figure 16 As shown, the flow channel unit 1013 includes six single-sided flow channels 1014 of equal length, with an angle of 120° between adjacent single-sided flow channels 1014; the six single-sided flow channels 1014 are combined to form a regular hexagonal annular flow channel. Multiple flow channel units 1013 are interconnected and combined to form a flow channel network.

[0106] Specifically, adjacent flow channel units 1013 share a single-sided flow channel 1014, such as... Figure 16 As shown.

[0107] The flow channel network provided in this embodiment offers a flow channel structure similar to a cellular network. The flow channel network has multiple interconnected single-sided flow channels 1014, and adjacent single-sided flow channels 1014 have a certain angle between them. When the coolant flows in the flow channel grid, it will continuously split to ensure that all single-sided flow channels 1014 have coolant flowing, thus guaranteeing the flow area of ​​the coolant and achieving uniform heat dissipation for the conformal phased array data link system.

[0108] In addition, as the coolant flows through the flow channel network, it is constantly divided, which reduces the flow rate of the coolant to a certain extent, making the heat exchange between the coolant and the signal acquisition and processing module 10 more efficient.

[0109] Compared with the prior art, the technical solution provided in this embodiment has at least one of the following beneficial effects:

[0110] The conformal phased array data link system of the present invention has reliable connections between components, a compact structure, a reasonable wiring design, and significant heat dissipation effect, making it suitable for missile guidance systems.

[0111] The conformal phased array data link system of the present invention uses aluminum alloy as the main support, which has high structural strength, large active circulation channel heat dissipation area, and short heat transfer path between the system and the heat source. It has good adaptability to the high temperature, vibration and impact environment of missiles, and ensures that the antenna's structural strength, rigidity, heat dissipation, connection reliability and maintainability meet the requirements.

[0112] The conformal phased array data link system of the present invention achieves rapid cooling of the system by circulating coolant in two active circulation paths on the antenna feeder bracket 5 and the signal acquisition and processing module 10. Compared with existing liquid cooling pipelines, the first and second active circulation paths of the present invention are connected in parallel to dissipate heat from the antenna radiating element 1 and TR component 3, the signal acquisition and processing module 10 and the secondary power supply 8 on the antenna feeder bracket 5, respectively. By superimposing the circulation paths, the heat dissipation efficiency is improved.

[0113] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
