Description

Technical Field

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

[0002] With the development of the times, the size and weight of the installation platforms of various equipment are getting smaller and smaller, and the use of equipment is becoming more diversified, which requires the active phased array to develop in the direction of miniaturization, lightness, and functional expansion. The cross-sectional dimensions of the back-end processing unit of the traditional active phased array are often larger than the cross-sectional dimensions of the array antenna, and the entire array system is large and heavy; when realizing the requirements of different functions of the array system, the traditional active phased array array has weak expandable and reconfigurable capabilities, and the system construction cycle and cost are high.

[0003] The X-band phased array has a moderate antenna size, so both brick and tile structures can be used. If the brick structure is used directly, the size and weight of the entire array are large; if the tile structure is used, the heat dissipation may need to adopt a two-phase flow heat dissipation method for ultra-high power transmitting arrays, which has low technical maturity and high risk. This paper proposes an X-band brick-tile hybrid reconfigurable array structure. The transverse cross-sectional size of the array back-end processing unit is smaller than the transverse cross-sectional size of the array antenna. The array back-end processing unit is divided into multiple regular sub-array processing modules according to the array scale. The antenna extension layer and the sub-array processing module are both reconfigurable units. The entire array system has strong scalability and flexible configuration. The sub-array processing module adopts a brick-tile hybrid structure, in which the TR component adopts a brick design and the other modules adopt a tile integrated design. The sub-array structure integrates the advantages of brick and tile, with low overall design difficulty and good heat dissipation performance, effectively reducing the longitudinal cross-sectional size 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-and-tile hybrid reconfigurable array structure.

[0005] The technical scheme for realizing 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 subarray 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 subarray 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 subarray unit, to realize the interface conversion from the output port of the array antenna to the input port of the subarray unit, and the 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; the array environmental control device is internally installed with a leakage alarm 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 the air circulation inside the entire array.

[0006] Furthermore, an antenna extension layer and an array antenna are installed on one side of the array feed unit, and a sub-array unit and an array control module are installed on the other side, and an 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 prior art, the present invention has the following significant advantages:

[0011] (1) Compact structure and low longitudinal profile height: The transverse profile size of the back-end processing unit of the array system is smaller than that of the array antenna, that is, the appearance of the back-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 profile 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, all other modules in the array system are installed from the rear end of the array to the front, which is simple to assemble and convenient to maintain.

[0013] (3) Stable and reliable heat dissipation with 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 consumption, 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 on the equipment, realizes real-time control of the cooling system status, and has high safety.

[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 solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present 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, which corresponds to the sub-array unit 3 one by one, 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 the air circulation inside the entire array. The present invention is an active phased array array surface structure, in which the antenna extension layer and the subarray unit are both reconfigurable units, and the array surface system is flexibly reconfigured; the subarray unit adopts a brick-and-tile hybrid architecture, which greatly reduces the longitudinal section height and realizes a lightweight design of the array surface.

[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 being used to install antenna combinations such as the antenna extension layer 4 and the array antenna 5, and the other side being used to install back-end processing units such as the sub-array unit 3 and the array control module 6, and multiple functional units such as the fluid distributor, condensation pipeline and array feed layer are integrated therein, so as to realize the fluid distribution inside the array system, the condensation prevention 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-tile hybrid structure, in which the TR component adopts a brick-type design, and the other modules (such as power supply, control module, power division network) adopt a tile-type integrated design, which effectively reduces the longitudinal section size of the subarray unit 3; the internal TR components of the subarray unit 3 correspond to the same number of array antennas 4, and the 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, and the multi-level flow of the fluid is realized through a blind plug fluid connector. The heat dissipation of the internal modules does not affect each other, 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, and each antenna extension layer 4 is an LRU module, corresponding one to one with the subarray unit 3. The interface conversion from the output port of the array antenna 5 to the input port of the subarray unit 3 is realized through the antenna extension layer 4; the output end cross-section of the antenna extension layer 4 is smaller than the input end cross-section, which ensures the feasibility of the 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 section size, effectively reducing the longitudinal section 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, 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 pipeline of the array feed unit 2. The condensing fan 8 blows air toward the ventilated condensing pipeline in which the circulating normal temperature coolant flows. This can not only allow the water vapor that may exist in the array to condense at the condensing pipeline, thereby avoiding the condensed water on other electronic modules and affecting the performance of the electronic modules, but also can drive the air circulation inside the entire array to achieve the heat dissipation of other electronic modules without liquid cooling conditions.

[0032] The technical features of the above embodiments may 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 only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
