Description

Technical Field

[0001] The present invention relates to active phased array technology, and in particular to an X-band brick-tile hybrid reconfigurable array structure. Background Art

[0002] With the development of the times, the size and weight of various equipment installation platforms are becoming smaller and lighter, and the use of equipment is becoming more diverse. This requires the development of active phased array arrays in the direction of miniaturization, lightweightness, and functional expansion. The cross-sectional dimensions of the back-end processing unit of traditional active phased array arrays are often larger than the cross-sectional dimensions of the array antenna, making the entire array system bulky and heavy. When meeting the requirements of the array system's different functions, traditional active phased array arrays have weak scalability and reconfiguration capabilities, resulting in high system construction cycles and costs.

[0003] Because X-band phased arrays have moderate antenna sizes, both brick and tile structures can be used. Directly adopting a brick structure results in a larger array size and weight. However, if a tile structure is used, heat dissipation for ultra-high-power transmit arrays may require a two-phase flow approach, which has low technical maturity and high risk. This paper proposes an X-band brick-and-tile hybrid reconfigurable array structure. The array's back-end processing unit has a smaller transverse cross-sectional dimension than the array antenna. Based on the array's size, the back-end processing unit is split into multiple regular sub-array processing modules. Both the antenna extension layer and the sub-array processing modules are reconfigurable units, making the entire array system highly scalable and flexible in configuration. The sub-array processing modules adopt a brick-and-tile hybrid structure, with the TR component adopting a brick design and the remaining modules adopting a tile-based integrated design. This sub-array structure combines the advantages of both brick and tile structures, offering low overall design difficulty, excellent heat dissipation performance, and effectively reducing the longitudinal cross-sectional dimension and weight of the entire array system. Summary of the Invention

[0004] The object of the present invention is to provide an X-band brick-tile hybrid reconfigurable array structure.

[0005] The technical solution for achieving the purpose of the present invention is: an X-band brick-and-tile hybrid reconfigurable array structure, comprising an array frame, an array feed unit, a sub-array unit, an antenna extension layer, an array antenna, an array control module, an array environmental control device and a condensing fan, wherein: the array feed unit internally integrates a fluid distributor, a condensing pipeline and an array feed layer; the sub-array unit adopts a brick-and-tile hybrid structure, and the internal TR components correspond to the same number of array antennas; the antenna extension layer adopts a separate design, corresponding one-to-one with the sub-array unit, to realize the interface conversion from the output port of the array antenna to the input port of the sub-array unit, and its output end cross-section is smaller than the input end cross-section; the array antenna adopts a linear array structure, and there is no one-dimensional expansion inside the antenna; the array control module uses the condensing wind inside the array to dissipate heat; a leakage alarm device is installed inside the array environmental control device, and a groove is reserved for liquid storage; the condensing fan is installed at the condensing pipeline of the array feed unit to drive air circulation inside the entire array.

[0006] Furthermore, the antenna extension layer and array antenna are installed on one side of the array feed unit, and the other side is used to install the sub-array unit and array control module, and the array environmental control device is located below the sub-array unit.

[0007] Furthermore, the sum of the transverse cross-sections of the sub-array unit and the array control module is smaller than the transverse cross-section size of the array antenna.

[0008] Furthermore, a three-dimensional parallel flow channel design is adopted inside the sub-array unit, and multi-level fluid circulation is achieved through blind-plug fluid connectors.

[0009] Furthermore, the array control module is installed on the upper edge of the array feed unit, adopts an open blade structure design, and is positioned and fixed by a guide rail.

[0010] Compared with the existing technology, the present invention has the following significant advantages:

[0011] (1) Compact structure and low longitudinal section height: The transverse section size of the back-end processing unit of the array system is smaller than that of the array antenna, that is, the rear-end structure of the array is shrunk, and the entire array structure is compact; the sub-array unit inside the array adopts a brick-and-tile hybrid architecture, which greatly reduces the longitudinal section height of the entire array and realizes a lightweight design of the array.

[0012] (2) Simple assembly and convenient maintenance: Except for the passive array antenna and antenna extension layer, the remaining modules in the array system are installed from the rear end to the front, which makes assembly simple and maintenance convenient.

[0013] (3) Stable and reliable heat dissipation and high safety: The array system adopts conventional liquid cooling. Each sub-array unit has an independent flow channel system. When the system pressure does not exceed 1 bar, the flow rate of 1.66L / min can remove 1.4kW of heat loss, which can meet the heat dissipation requirements of most high-power transceiver arrays. The heat dissipation is stable and reliable. The array system is designed with an array environmental control device. Through the water-electric control joint protection design, it solves the impact of abnormal coolant conditions that may cause damage to the equipment, realizes real-time control of the cooling system status, and has high safety of the array system.

[0014] (4) Flexible array system reconstruction: The sub-array units correspond one-to-one to the antenna expansion layers, and are the smallest LRU components in the array system. The array can be reconstructed simultaneously according to usage requirements, with flexible configuration, which greatly reduces the system construction cycle. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0024] like Figure 1 、 Figure 2 as well as Figure 3 The invention discloses an X-band brick-and-tile hybrid reconfigurable array structure, comprising an array frame 1, an array feed unit 2, a sub-array unit 3, an antenna extension layer 4, an array antenna 5, an array control module 6, an array environmental control device 7 and a condensing fan 8; the array feed unit 2 internally integrates multiple functional units such as a fluid distributor, a condensing pipeline and an array feed layer; the sub-array unit 3 adopts a brick-and-tile hybrid structure, and the internal TR components correspond to the same number of array antennas 5; the antenna extension layer 4 adopts a separate design, corresponding one-to-one with the sub-array unit 3, and its output end cross-section is smaller than the input end cross-section; the array antenna 5 adopts a linear array structure, and there is no one-dimensional expansion inside the antenna; the array control module 6 uses the condensing wind inside the array to dissipate heat; the array environmental control device 7 is internally installed with a leakage alarm device, and a groove is reserved for liquid storage; the condensing fan 8 is installed at the condensing pipeline of the array feed unit 2 to drive air circulation inside the entire array. The present invention is an active phased array array structure. The antenna extension layer and sub-array units are both reconfigurable units, and the array system can be flexibly reconfigured. The sub-array units adopt a brick-and-tile hybrid architecture, which greatly reduces the longitudinal section height and realizes a lightweight and thin array design.

[0025] In a further embodiment, Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4 As shown, the array feed unit 2 serves as the main frame structure, with one side used to install antenna combinations such as the antenna extension layer 4 and the array antenna 5, and the other side used to install back-end processing units such as the sub-array unit 3 and the array control module 6. In addition, it integrates multiple functional units such as the fluid distributor, condensation pipeline and array feed layer, so as to realize the fluid distribution within the array system, the prevention of condensation of the electronic module and the simple wiring of the back-end processing unit in a limited space, thereby ensuring that the array system has the advantages of high integration, compact structure and convenient maintenance.

[0026] In a further embodiment, Figure 2 、 Figure 3 as well as Figure 5 As shown, the subarray unit 3 adopts a brick-and-tile hybrid structure, in which the TR components adopt a brick-type design, and the remaining modules (such as the power supply, control module, and power division network) adopt a tile-type integrated design, effectively reducing the longitudinal cross-sectional dimensions of the subarray unit 3. The internal TR components of the subarray unit 3 correspond to the same number of array antennas 4, and this number is an even number. The subarray can be expanded according to actual usage, and the subarray has good scalability. The subarray unit 3 adopts a three-dimensional parallel flow channel design inside, and multi-level fluid circulation is achieved through blind-plug fluid connectors. The internal modules do not affect each other's heat dissipation, and the heat dissipation is efficient and reliable.

[0027] In a further embodiment, Figure 3 、 Figure 6As shown, the antenna extension layer 4 adopts a separate design. Each antenna extension layer 4 is an LRU module, corresponding one-to-one to the subarray unit 3. The antenna extension layer 4 realizes the interface conversion from the output port of the array antenna 5 to the input port of the subarray unit 3; the output end cross-section of the antenna extension layer 4 is smaller than the input end cross-section, ensuring the feasibility of array system expansion.

[0028] In a further embodiment, Figure 2 、 Figure 3 As shown, the array antenna 5 adopts a linear array structure, and there is no one-dimensional expansion inside the antenna. The height of the one-dimensional expansion is left to the antenna expansion layer 4, so that the two-dimensional expansion of the array antenna 5 is achieved without increasing the longitudinal cross-sectional size, effectively reducing the longitudinal cross-sectional size of the array surface.

[0029] In a further embodiment, Figure 1 、 Figure 2 、 Figure 3 As shown, the array control module 6 is installed on the upper edge of the array feed unit 2, adopts an open blade structure design, is positioned and fixed by guide rails, and uses the circulating condensing air inside the array system to dissipate heat for the module.

[0030] In a further embodiment, Figure 2 、 Figure 7 As shown, a leakage alarm device is installed inside the array environmental control device 7. Through the water-electricity control joint protection design, the impact of abnormal coolant conditions that may cause damage to the equipment is resolved, the array cooling system status can be controlled in real time, and the liquid cooling safety protection performance of the array system is improved; the array environmental control device 7 has a reserved groove for liquid storage inside, which can store a part of the leaked coolant to prevent the coolant from flowing everywhere.

[0031] In a further embodiment, Figure 2 、 Figure 4 As shown, the condensing fan 8 is installed at the condensing pipe of the array feed unit 2. The condensing fan 8 blows air toward the ventilated condensing pipe with circulating normal temperature coolant flowing inside. This not only allows the water vapor that may exist in the array to condense at the condensing pipe, thereby avoiding the condensation water on other electronic modules and affecting the performance of the electronic modules, but also can drive the air circulation inside the entire array, thereby realizing the heat dissipation of other electronic modules without liquid cooling conditions.

[0032] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present application shall be determined by the appended claims.
