[0050] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0052] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0053] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0054] To protect the antenna, a radome is usually installed to place the antenna in a relatively sealed environment to prevent it from being eroded by the harsh natural environment under open conditions, which may lead to problems such as performance degradation and shortened service life. However, the sealed environment prevents the heat generated by the antenna from being discharged in time, causing the ambient temperature of the antenna to rise, which has a significant impact on the electrical modules inside the antenna and can even cause it to burn out.

[0055] Currently, the heat dissipation structure used for the antenna is usually independent of the antenna structure, and a hose is used to connect the fan and the environment in which the antenna is located, resulting in a large overall size and poor integration, which is not conducive to the miniaturization of the antenna volume and the integrated setting of the antenna.

[0056] The present invention provides a heat dissipation integrated antenna 100 .

[0057] See also Figure 1-Figure 3In one embodiment of the present invention, the heat dissipation integrated antenna 100 has a first direction extending along its height direction, including a reflective base 1, the reflective base 1 is made of a metal material (such as copper), and the reflective base 1 has a receiving cavity 11. In the first direction, one side of the reflective base 1 has an opening 12 connected to the outside and the receiving cavity 11; a cover plate 2 is provided on the opening 12 to seal the receiving cavity 11, so that the receiving cavity 11 constitutes a sealed space for placing the antenna body 10; the material of the cover plate 2 can be glass fiber, epoxy resin or acrylic and other wave-transmitting materials, so as to achieve the purpose of providing a relatively sealed environment for the antenna body 10 by covering the opening 12 on the receiving cavity 11 through the cover plate 2 without affecting the signal transmission of the antenna body 10; the active heat dissipation structure includes an air inlet 3, an air outlet 4 and a fan module 5; the air inlet The air inlet 3 is provided on the reflecting base 1, and the air inlet 3 can be provided on the bottom wall of the accommodating cavity 11 or on the side wall of the accommodating cavity 11 (as long as the air intake requirements can be met), and the air inlet 3 is used to connect the outside world with the sealed space; the air outlet 4 is provided on the reflecting base 1, and the air outlet 4 can be provided on the bottom wall of the accommodating cavity 11 or on the side wall of the accommodating cavity 11 (as long as the wind introduced from the air inlet 3 can be discharged outward from the sealed space), and the air outlet 4 is used to connect the outside world with the sealed space; and the fan module 5 is provided in the sealed space, and is used to draw the external cold air into the sealed space through the air inlet 3, and discharge it outward through the air outlet 4; a wiring hole (not shown in the figure) connected to the outside world is provided on the reflecting base 1, which is used to provide power for the normal operation of the fan module 5 and the antenna body 10 and the transmission of communication signal data.

[0058] Conventional antennas are typically used in conjunction with a reflective floor (a flat metal structure). Specifically, the antenna body 10 is mounted on the upper surface of the reflective floor, which reflects electromagnetic waves emitted by the antenna body 10 and enhances the antenna's radiation directionality. The present invention improves the flat reflective floor into a reflective base 1 with a housing 11. A cover 2 is provided at the opening 12 of the housing 11 to seal the housing 11. This allows the antenna body 10 to be placed in a relatively sealed environment, protecting it from exposure to harsh natural conditions, which could lead to performance degradation and a shortened service life. For example, the cover 2 can protect the antenna body 10 from direct erosion by rain, snow, hail, dust, and other inclement weather, preventing damage to the antenna body 10 due to accumulation of pollutants or mechanical impact. It can also isolate the antenna body 10 from corrosive media such as moisture, salt spray, and acid rain, preventing direct contact with the metal antenna body 10. For example, radomes on ships or coastal base stations often utilize epoxy resin sealing technology, significantly reducing the risk of corrosion caused by salt spray infiltration.

[0059] In this embodiment, the antenna body 10 is placed in a receiving cavity 11 located in the reflecting base 1. Compared with the reflecting floor (flat structure) of a traditional antenna, it is equivalent to adding a metal side wall (that is, the side wall of the receiving cavity 11) on each side of the antenna body 10. The metal side wall can reflect the electromagnetic waves that originally diffused to the surroundings back to the main radiation direction. This reflection reduces the leakage of energy to non-target directions (such as the back or side), so that more energy is concentrated in the main direction, thereby improving the gain of the antenna. The gain represents the power density radiated by the antenna in a specific direction, which is equivalent to the ability of the antenna to concentrate energy in a certain direction. The higher the gain, the more concentrated the signal and the farther it is transmitted (but the coverage range is narrower); the lower the gain, the more dispersed the signal and the wider the coverage range (but the transmission distance is not far).

[0060] When cooling, The fan module 5 starts to draw cold air from the outside environment into the sealed space through the air inlet 3. Finally, it is discharged from the air outlet 4, thereby taking away the higher temperature gas in the sealed space and discharging it. The sealed space ultimately achieves the effect of lowering the temperature and cooling the space where the antenna body 10 is located; In this embodiment, the originally flat reflective floor is improved into a reflective base 1 having a receiving cavity 11, so that the components for dissipating heat for the antenna body 10 are accommodated in the reflective base 1, thereby achieving a high degree of integration between the heat dissipation components and the antenna body 10, which contributes to the miniaturization of the antenna volume; at the same time, the antenna body 10 is placed in the receiving cavity 11, and the radiation signal of the antenna body 10 is better guided by the side wall of the receiving cavity 11, thereby effectively improving the gain of the antenna.

[0061] Preferably, the antenna body 10 in this solution is provided with heat dissipation fins, which can effectively increase the heat dissipation area of the antenna body 10 and improve the heat dissipation efficiency, thereby quickly transferring the heat of the antenna body 10 to the surrounding environment to reduce the temperature of the antenna body 10.

[0062] In one embodiment of the present invention, referring to Figure 2 As shown, the reflective base 1 includes a bottom plate 13 and side plates 14. There are multiple side plates 14, and the multiple side plates 14 are spliced end to end. The multiple side plates 14 can be separately set or integrated. When a separate setting is adopted, fasteners can be used to fix the adjacent two side plates 14 together; and the multiple side plates 14 are connected to the bottom plate 13 on the side facing the bottom plate 13, so that the side plates 14 and the bottom plate 13 are enclosed to form a receiving cavity 11; the receiving cavity 11 is formed with an opening 12 on the side away from the bottom plate 13.

[0063] In this solution, the number of side panels 14 can be 4 or any other number. There is no limit on the number of side panels 14, as long as they can cooperate with the bottom panel 13 and enclose the accommodating cavity 11. At the same time, the side panels 14 and the bottom panel 13 can be integrated or separated. When a separated setting is adopted, fasteners can be used to fix the side panels 14 to the bottom panel 13. The drawings of this application show an example in which the reflective base 1 includes 4 side panels 14.

[0064] In one embodiment of the present invention, referring to Figure 3 、 Figure 4 As shown, the heat dissipation integrated antenna 100 further includes an air inlet cavity 141, and an air inlet cavity 141 is provided in at least one side panel 14; the air inlet cavity 141 has a first inlet 31 communicating with the outside and a second inlet 32 communicating with the sealed space, the first inlet 31 and the second inlet 32 forming an air inlet 3, and a fan module 5 is provided in the air inlet cavity 141; Figure 3 As shown, it shows a schematic diagram of the state where the fan module 5 is removed from the air inlet cavity 141; Figure 4 As shown, it is a schematic diagram showing the state of the fan module 5 located in the air inlet cavity 141; the fan module 5 is used to draw cold air from the outside into the air inlet cavity 141 through the first inlet 31, and send it into the sealed space through the second inlet 32, thereby realizing the cold air in the external environment being sent into the sealed space through the first inlet 31 and the second inlet 32, thereby achieving the effect of cooling the antenna body 10.

[0065] In one embodiment of the present invention, referring to Figure 3 、 Figure 4 、 Figure 5 As shown, in the first direction, the first inlet 31 penetrates at least part of the bottom wall of the air inlet cavity 141; the second inlet 32 is provided on a side wall of the side plate 14 facing the sealed space, for connecting the sealed space and the air inlet cavity 141; the fan module 5 is provided between the first inlet 31 and the second inlet 32, and the air supply side of the fan module 5 corresponds to the second inlet 32; Figure 3 As shown, a shielding grille 143 (made of metal material, such as copper) is provided at the second inlet 32. The shielding grille 143 is provided to shield the electromagnetic radiation signal generated when the fan module 5 is working normally, so as not to affect the performance of the antenna body 10; Figure 4 As shown, a filter screen 6 is provided at the first inlet 31 for filtering debris in the air to prevent it from entering the sealed space along with the air flow.

[0066] The shielding grille 143 in this embodiment not only meets the air intake requirements, but also shields the electromagnetic radiation signals generated by the fan module 5 when it is working. Although the shielding grille 143 does not completely wrap the fan module 5, the gap of the shielding grille 143 is small, which can prevent most electromagnetic signals from passing through the shielding grille 143, thereby not causing substantial interference to the performance of the antenna body 10.

[0067] In this embodiment, a plurality of second inlets 32 may be provided on a side wall of the side panel 14 facing the accommodating cavity 11, that is, the plurality of second inlets 32 are all connected to the air inlet cavity 141, and a fan module 5 is provided at each second inlet 32, and a shielding grille 143 (for shielding the electromagnetic radiation signal generated when the fan module 5 is working) is provided at each second inlet 32, thereby further improving the temperature reduction and cooling effect of the antenna body 10.

[0068] In one embodiment of the present invention, referring to Figure 3 As shown, the heat dissipation integrated antenna 100 further includes an air outlet cavity 142, which is disposed in the side panel 14 adjacent to and / or opposite to the air inlet cavity 141. Figure 3 The figure shows that an air outlet cavity 142 is provided only in the side panel 14 adjacent to the air inlet cavity 141; the air outlet cavity 142 has a first outlet 41 connected to the sealed space and a second outlet 42 connected to the outside, and the first outlet 41 and the second outlet 42 constitute the air outlet 4; in this embodiment, by reasonably setting the relative positions of the first outlet 41 and the second inlet 32, the cold air entering the sealed space through the second inlet 32 can flow through the position of the antenna body 10 in the sealed space as much as possible, that is, the cold air can contact the antenna body 10 as much as possible in the sealed space, thereby improving the heat exchange efficiency with the antenna body 10 and thus improving the temperature reduction and cooling effect; then enter the air outlet cavity 142 from the first outlet 41 and be discharged to the outside from the second outlet 42; avoid the situation where the cold air is discharged from the first outlet 41 as soon as it enters the sealed space from the second inlet 32, or the cold air hardly passes through the antenna body 10 when flowing in the sealed space.

[0069] In one embodiment of the present invention, referring to Figure 3 、 Figure 4 As shown, in the length direction of the side panel 14, the air outlet cavity 142 is set through the side panel 14 to form a second outlet 42 at each end of the length direction of the side panel 14. The setting of the two air outlets 4 improves the efficiency of discharging air in the sealed space to the outside, which can further improve the cooling effect; the first outlet 41 is set on the side wall of the side panel 14 facing the sealed space, and is used to connect the sealed space and the air outlet cavity 142.

[0070] In this embodiment, cool air enters the sealed space from the second inlet 32 under the action of the fan module 5, and enters the air outlet cavity 142 from the first outlet 41. In the longitudinal direction of the side panel 14, since the two ends of the air outlet cavity 142 pass through the side panel 14, the air entering the air outlet cavity 142 can be discharged outward from the two second outlets 42. The provision of the two second outlets 42 is equivalent to increasing the air outlet cross-section, which helps to improve the efficiency of air discharge. Since the first inlet 31 passes through the bottom wall of the air inlet cavity 141, when the fan module 5 is in operation, the cool air located below the reflective base 1 is sent into the sealed space. The second outlets 42 are provided on the side walls at both ends along the longitudinal direction of the side panel 14, so the hot air is discharged from the peripheral side of the reflective base 1, thereby staggering the cool air drawn in by the fan module 5 and the hot air discharged from the sealed space as much as possible.

[0071] In one embodiment of the present invention, referring to Figure 6 、 Figure 7 As shown, another arrangement of the air inlet cavity 141 is proposed, that is, in the length direction of the side panel 14, the air inlet cavity 141 is arranged through the side panel 14 to form a first inlet 31 at each end of the length direction of the side panel 14; the second inlet 32 is arranged on a side wall of the side panel 14 facing the sealed space, for connecting the sealed space and the air inlet cavity 141, and the fan module 5 is arranged at a position corresponding to the second inlet 32, that is, the air supply side of the fan module 5 corresponds to the position of the second inlet 32; a shielding grille 143 is also provided at the second inlet 32 for shielding the electromagnetic radiation signal generated when the fan module 5 is working.

[0072] In this embodiment, the second inlet 32 and the fan module 5 can also be set to multiple and all are connected to the air inlet cavity 141 (used to improve the air supply efficiency into the sealed space. At the same time, the setting of multiple second inlets 32 enables the cold air sent into the sealed space to better contact with the antenna body 10, thereby improving the heat exchange efficiency), and a shielding grille 143 is provided at each second inlet 32; in order to prevent debris in the external environment from entering the sealed space with the flow of air, in this embodiment, filter nets 6 are respectively provided at the two first inlets 31 for filtering debris in the air.

[0073] In one embodiment of the present invention, referring to Figure 7As shown, in the first direction, the air outlet 4 is provided through the bottom plate 13; preferably, the air outlet 4 should be provided on the opposite side of the second inlet 32, so that the antenna body 10 is located between the air outlet 4 and the second inlet 32. This ensures that when external cold air enters the sealed space from the second inlet 32, the area between the second inlet 32 and the air outlet 4 forms a flow path for the airflow (the antenna body 10 is located on this flow path), thereby allowing the antenna body 10 to come into contact with the cold air as much as possible and exchange heat, thereby improving the temperature reduction and cooling effect. Because the first inlet 31 is formed on the peripheral side of the reflective base 1 and the air outlet 4 is provided through the bottom plate 13, when the fan module 5 is in operation, it will deliver cold air located on the peripheral side of the reflective base 1 into the sealed space, while exhausting the hot air in the sealed space through the air outlet 4 to the lower area of the reflective base 1. This ensures that the cold air drawn in by the fan module 5 and the hot air discharged from the sealed space are staggered as much as possible.

[0074] The present invention also proposes an antenna array, which includes at least two heat dissipation integrated antennas 100, which are arranged in sequence. In order to make the antenna array have a more compact size, the two adjacent heat dissipation integrated antennas 100 are set close to each other; wherein, the specific structure of the heat dissipation integrated antenna 100 refers to the above embodiment. Since this antenna array adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. Figure 8 、 Figure 9 As shown, it is a schematic diagram of the antenna array structure formed under one embodiment of the heat dissipation integrated antenna 100; in the longitudinal direction of the side panel 14, the air outlet cavity 142 is set through the side panel 14 to form a second outlet 42 at each end of the longitudinal direction of the side panel 14. In the arrangement direction of the second outlets 42, the air outlet cavities 142 in two adjacent heat dissipation integrated antennas 100 are connected end to end to form an exhaust channel.

[0075] When the fan module 5 is working, the cold air located below the antenna array is drawn into the sealed space, and the hot air is discharged into the air outlet cavity 142 through the first outlet 41, and finally discharged outward from the peripheral side of the antenna array through the exhaust channel composed of multiple air outlet cavities 142 connected end to end in sequence, so that the air drawn in by the fan module 5 and the air discharged from the sealed space are staggered as much as possible, thereby achieving better temperature reduction and cooling effects.

[0076] Reference Figure 10 、 Figure 11As shown, it is a schematic diagram of the antenna array structure composed of another embodiment of the heat dissipation integrated antenna 100; in the length direction of the side panel 14, the air inlet cavity 141 is set through the side panel 14 to form a first inlet 31 at each end of the length direction of the side panel 14. In the arrangement direction of the first inlet 31, the air inlet cavities 141 in two adjacent heat dissipation integrated antennas 100 are connected end to end to form an air intake channel.

[0077] When the fan module 5 is working, the cold air located around the antenna array is drawn into the air inlet channel composed of multiple air inlet cavities 141 connected end to end, and then enters the sealed space through the second inlet 32, and the hot air is directly discharged to the space below the antenna array through the air outlet 4, so that the cold air drawn in by the fan module 5 and the hot air discharged from the sealed space are staggered as much as possible, thereby achieving better cooling effect.

[0078] In one embodiment of the present invention, referring to Figure 8 、 Figure 10 As shown, the antenna array has mutually perpendicular X and Y directions, and the antenna array also includes a reflective substrate 7; a plurality of reflective transverse plates 8, the plurality of reflective transverse plates 8 extending along the X direction, and the plurality of reflective transverse plates 8 are spaced apart along the Y direction; and a plurality of reflective longitudinal plates 9, the plurality of reflective longitudinal plates 9 extending along the Y direction, and the plurality of reflective longitudinal plates 9 are spaced apart along the X direction; the reflective transverse plates 8 and the reflective longitudinal plates 9 are connected to the reflective substrate 7 toward the side of the reflective substrate 7, so that the reflective transverse plates 8, the reflective longitudinal plates 9 and the reflective substrate 7 enclose a plurality of accommodating cavities 11.

[0079] In this embodiment, the reflective substrate 7 and the reflective transverse plate 8 and the reflective longitudinal plate 9 can be arranged as an integral whole or as separate parts. The reflective transverse plate 8 and the reflective longitudinal plate 9 are arranged in an alternating manner, thereby forming a plurality of accommodating cavities 11 together with the reflective substrate 7. Since the reflective longitudinal plates 9 and the reflective transverse plates 8 are arranged in an alternating manner, the reflective longitudinal plates 9 and the reflective transverse plates 8 are divided into a plurality of small sections, that is, part of the reflective transverse plate 8 and part of the reflective longitudinal plate 9 corresponding to the accommodating cavity 11 correspond to a small section, each small section constitutes a side plate 14, and part of the reflective substrate 7 corresponding to the accommodating cavity 11 constitutes a bottom plate 13; thereby, two adjacent accommodating cavities 11 in the antenna array share a side plate 14, making the antenna array as a whole more compact, effectively reducing the overall size of the antenna array, and also reducing the consumption of materials.

[0080] It is worth noting that: in this embodiment, since two adjacent accommodating chambers 11 share a side plate 14, at this time, Figure 8As shown, the position of the air outlet cavity 142 is preferably set in the side panel 14 adjacent to the air inlet cavity 141, because the air inlet cavity needs to be set in the side panel 14 opposite to the air inlet cavity 141, and the setting of the air inlet cavity makes it impossible to set an additional air outlet cavity 142; or the position of the air outlet cavity 142 can also be set in the side panel 14 opposite to the air inlet cavity 141. At this time, it is necessary to compress the sizes of the air outlet cavity 142 and the air inlet cavity 141 in the side panel 14 opposite to the air inlet cavity 141, that is, in the thickness direction of the side panel 14, so that the air outlet cavity 142 and the air inlet cavity 141 can be set in the same side panel 14 at the same time.

[0081] In this embodiment, the material of the reflective substrate 7, the reflective longitudinal plate 9 and the reflective transverse plate 8 is metal, such as copper; in the antenna array, the cover plate 2 can be one, and all the accommodating cavities 11 are sealed, thereby providing a relatively sealed space for the antenna body 10; the cover plate 2 can also include sub-plates that match the number of accommodating cavities 11, that is, each accommodating cavity 11 corresponds to a sub-plate, for achieving a sealing effect.

[0082] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made by utilizing the contents of the present invention's description and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
