[0024] Based on the protection of the antenna, an antenna cover is usually provided to place the antenna in a relatively sealed environment to avoid problems such as performance degradation and shortened service life caused by being eroded by harsh natural environments under open-air conditions; however, the sealed environment causes the heat generated when the antenna works to be unable to be discharged in time, resulting in an increase in the environmental temperature where the antenna is located, which has a greater impact on the electrical modules inside the antenna and may even cause burnout in severe cases.

[0025] Currently, the heat dissipation structure for the antenna is usually independent of the antenna structure, and a hose is used to connect the fan and the environment where the antenna is located, resulting in a relatively large overall size and poor integration, which is not conducive to the miniaturization of the antenna volume and the integrated setting of the antenna.

[0026] The present invention proposes a heat dissipation integrated antenna 100.

[0027] Please refer to Figures 1-3, in an embodiment of the present invention, the heat dissipation integrated antenna 100 has a first direction extending along its height direction, and includes a reflection base 1. The reflection base 1 is made of a metal material (such as copper), and the reflection base 1 has a receiving cavity 11. In the first direction, one side of the reflection base 1 has an opening 12 communicating with the outside and the receiving cavity 11; a cover plate 2 is covered on the opening 12 for sealing the receiving cavity 11 so that the receiving cavity 11 forms a sealed space for placing the antenna body 10; the material of the cover plate 2 can be a wave-transmitting material such as fiberglass, epoxy resin or acrylic, so as to realize that on the basis of not affecting the signal transmission of the antenna body 10, the cover plate 2 is covered on the opening 12 of the receiving cavity 11 to provide a relatively sealed environment for 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 3 is arranged on the reflection base 1, and the air inlet 3 can be arranged on the bottom wall of the receiving cavity 11 or on the side wall position of the receiving cavity 11 (as long as the air inlet requirement can be met), and the air inlet 3 is used for communicating the outside with the sealed space; the air outlet 4 is arranged on the reflection base 1, and the air outlet 4 can be arranged on the bottom wall of the receiving cavity 11 or on the side wall position of the receiving cavity 11 (as long as the air introduced from the air inlet 3 can be discharged out of the sealed space), and the air outlet 4 is used for communicating the outside with the sealed space; and the fan module 5 is arranged in the sealed space for pumping outside cold air into the sealed space through the air inlet 3 and discharging it outside through the air outlet 4; a wiring hole communicating with the outside is arranged on the reflection base 1 (not shown in the figure) for providing electrical energy and the transmission of communication signal data for the normal operation of the fan module 5 and the antenna body 10.

[0028] When a traditional antenna is working, it is usually used in combination with a reflection floor (a flat metal structure), that is, the antenna body 10 is installed on the upper surface of the reflection floor, and the reflection floor is used to reflect the electromagnetic waves emitted by the antenna body 10 to enhance the radiation directivity of the antenna; the technical solution of the present invention improves the flat reflection floor into a reflection base 1 with a receiving cavity 11 on the basis of the traditional antenna, and a cover plate 2 is covered at the opening 12 of the receiving cavity 11 for sealing the receiving cavity 11, so that the antenna body 10 is placed in a relatively sealed environment, avoiding problems such as performance degradation and shortened service life caused by the antenna body 10 being eroded by harsh natural environments under open-air conditions; for example: the setting of the cover plate 2 in the natural environment can resist the direct erosion of harsh weather such as rain, snow, hail and sand, and prevent the surface of the antenna body 10 from being damaged due to the accumulation of pollutants or mechanical collisions; and it can isolate external moisture, salt mist, acid rain and other corrosive media, avoiding direct contact with the metal antenna body 10. For example, the antenna covers of ships or coastal base stations often adopt epoxy resin sealing technology, significantly reducing the corrosion risk caused by the infiltration of salt mist.

[0029] In this embodiment, the antenna body 10 is placed in the accommodation cavity 11 located within the reflection base 1. Compared with the reflection floor (flat plate structure) of traditional antennas, it is equivalent to having a metal sidewall (i.e., the sidewall of the accommodation cavity 11) around the antenna body 10 respectively. The metal sidewall can reflect the electromagnetic waves that originally spread around back to the main radiation direction. This reflection reduces the leakage of energy to non-target directions (such as the back or side), enabling more energy to be concentrated in the main direction, thereby improving the gain of the antenna. Here, 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 can be transmitted (but the coverage range becomes narrower); the lower the gain, the more dispersed the signal and the wider the coverage range (but it cannot be transmitted far).

[0030] During heat dissipation, the fan module 5 starts to draw cold air from the external environment into the sealed space through the air inlet 3 and finally discharges it out through the air outlet 4, thereby achieving the effect of taking away the relatively hot gas in the sealed space and discharging it from the sealed space, ultimately realizing the cooling effect on the space where the antenna body 10 is located. In this embodiment, by improving the originally flat reflection floor into the reflection base 1 with the accommodation cavity 11, the components for dissipating heat from the antenna body 10 are accommodated in the reflection base 1, realizing the high integration of the heat dissipation components and the antenna body 10, which helps to miniaturize the size of the antenna. At the same time, the antenna body 10 is placed in the accommodation cavity 11, and the sidewall of the accommodation cavity 11 can better guide the radiation signal of the antenna body 10, effectively improving the gain of the antenna.

[0031] 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.

[0032] In an embodiment of the present invention, referring to Figure 2 As shown, the reflection 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 arranged or integrally arranged. When separately arranged, fasteners can be used to fixedly connect adjacent side plates 14. And one side of the multiple side plates 14 facing the bottom plate 13 is connected to the bottom plate 13, so that the side plates 14 and the bottom plate 13 enclose to form the accommodation cavity 11. An opening 12 is formed on the side of the accommodation cavity 11 facing away from the bottom plate 13.

[0033] In this solution, the number of side plates 14 can be 4 or other numbers. There is no limit to the number of side plates 14, as long as it can cooperate with the bottom plate 13 and enclose the accommodation cavity 11; at the same time, the side plate 14 and the bottom plate 13 can be integrally arranged or separately arranged. When separately arranged, fasteners can be used to fix the side plate 14 on the bottom plate 13; the figure example showing that the reflection base 1 includes 4 side plates 14 is shown in the attached drawings of this application.

[0034] 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 at least one side plate 14 is provided with the air inlet cavity 141; the air inlet cavity 141 has a first inlet 31 communicating with the outside and a second inlet 32 communicating with the sealed space, and the first inlet 31 and the second inlet 32 form an air inlet 3, and the fan module 5 is arranged in the air inlet cavity 141; as Figure 3 shown, the figure shows a schematic diagram of the state where the fan module 5 is removed from the air inlet cavity 141; as Figure 4 shown, the figure shows a schematic diagram of the state where the fan module 5 is located in the air inlet cavity 141; the fan module 5 is used to draw outside cold air into the air inlet cavity 141 through the first inlet 31 and send it into the sealed space through the second inlet 32, so as to realize sending the cold air in the outside environment into the sealed space through the first inlet 31 and the second inlet 32, and achieve the effect of cooling the antenna body 10.

[0035] 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 arranged on a side wall of the side plate 14 facing the sealed space and is used to communicate the sealed space and the air inlet cavity 141; the fan module 5 is arranged between the first inlet 31 and the second inlet 32, and the air supply side of the fan module 5 corresponds to the position of the second inlet 32; as Figure 3 shown, a shielding grid 143 (made of a metal material, such as copper) is provided at the second inlet 32. The reason for setting the shielding grid 143 is to shield the electromagnetic radiation signals generated during the normal operation of the fan module 5 so as not to affect the performance of the antenna body 10; as Figure 4 shown, a filter net 6 is provided at the first inlet 31 to filter the sundries in the air so as not to enter the sealed space along with the air flow.

[0036] In this embodiment, the shielding grille 143 meets the air intake requirement and shields the electromagnetic radiation signals generated when the fan module 5 operates. Although the shielding grille 143 does not completely wrap the fan module 5, the gaps of the shielding grille 143 are small, which can prevent most electromagnetic signals from passing through the shielding grille 143, thus not causing substantial interference to the performance of the antenna body 10.

[0037] In this embodiment, a plurality of second inlets 32 may be provided on the side wall of the side plate 14 facing the accommodation cavity 11, that is, the plurality of second inlets 32 communicate with the air intake cavity 141, and a fan module 5 is provided at each second inlet 32, and a shielding grille 143 (for shielding the electromagnetic radiation signals generated when the fan module 5 operates) is provided at each second inlet 32, thereby further improving the cooling effect of the antenna body 10.

[0038] In one embodiment of the present invention, refer to Figure 3 As shown, the heat dissipation integrated antenna 100 further includes an air outlet cavity 142, and the air outlet cavity 142 is arranged in the side plate 14 adjacent to and / or opposite to the air intake cavity 141, wherein Figure 3 The figure shows an illustration in which the air outlet cavity 142 is only arranged in the side plate 14 adjacent to the air intake cavity 141; the air outlet cavity 142 has a first outlet 41 communicating with the sealed space and a second outlet 42 communicating with the outside, and the first outlet 41 and the second outlet 42 form an 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, improving the heat exchange efficiency with the antenna body 10, and further improving the cooling effect; then enter the air outlet cavity 142 from the first outlet 41 and be discharged outwards from the second outlet 42; avoiding the situation that the cold air just enters the sealed space from the second inlet 32 and is discharged from the first outlet 41 or the cold air hardly passes through the antenna body 10 when flowing in the sealed space.

[0039] In one embodiment of the present invention, refer to Figure 3 、 Figure 4 As shown, in the length direction of the side plate 14, the air outlet cavity 142 runs through the side plate 14, so that a second outlet 42 is formed at each end of the side plate 14 in the length direction. The arrangement of the two air outlets 4 improves the efficiency of discharging the air in the sealed space outwards, and can further improve the cooling effect; the first outlet 41 is arranged on the side wall of the side plate 14 facing the sealed space and is used to communicate the sealed space and the air outlet cavity 142.

[0040] In this embodiment, under the action of the fan module 5, cold air enters the sealed space from the second inlet 32, and enters the air outlet cavity 142 from the first outlet 41. In the length direction of the side plate 14, since both ends of the air outlet cavity 142 penetrate through the side plate 14, the air entering the air outlet cavity 142 can be discharged outward from the two second outlets 42. The arrangement of the two second outlets 42 is equivalent to increasing the air outlet cross-section, which helps to improve the efficiency of air discharge outward. Since the first inlet 31 penetrates through the bottom wall of the air inlet cavity 141, when the fan module 5 works, the cold air located below the reflection base 1 is sent into the sealed space, and the second outlets 42 are arranged on the side walls at both ends in the length direction of the side plate 14. Therefore, the hot air is discharged from the circumferential side surface of the reflection base 1, 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.

[0041] In an embodiment of the present invention, referring to Figure 6 、 Figure 7 As shown, another setting method of the air inlet cavity 141 is proposed, that is, in the length direction of the side plate 14, the air inlet cavity 141 penetrates through the side plate 14, so as to form a first inlet 31 at each end in the length direction of the side plate 14; the second inlet 32 is arranged on the side wall of the side plate 14 facing the sealed space, and is used to connect the sealed space and the air inlet cavity 141. 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 grid 143 is also provided at the second inlet 32, which is used to shield the electromagnetic radiation signal generated when the fan module 5 works.

[0042] In this embodiment, the second inlet 32 and the fan module 5 can also be set to be multiple and are all connected to the air inlet cavity 141 (to improve the air supply efficiency to the sealed space. At the same time, the arrangement of multiple second inlets 32 enables the cold air sent into the sealed space to better contact the antenna body 10 and improve the heat exchange efficiency), and a shielding grid 143 is provided at each second inlet 32; in order to prevent sundries in the external environment from entering the sealed space along with the air flow, in this embodiment, filter nets 6 are respectively provided at the two first inlets 31 to filter sundries in the air.

[0043] In an embodiment of the present invention, referring to Figure 7As shown, in the first direction, the air outlet 4 penetrates through the bottom plate 13; preferably, the air outlet 4 should be arranged 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. Thus, when the outside 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 moving channel for the air flow (the antenna body 10 is located on this moving channel), so that the antenna body 10 can be in contact with the cold air as much as possible and perform heat exchange to improve the cooling effect. Since the first inlet 31 is formed on the circumferential side surface of the reflection base 1 and the air outlet 4 penetrates through the bottom plate 13, when the fan module 5 works, the cold air located on the circumferential side of the reflection base 1 is sent into the sealed space, and the hot air in the sealed space is discharged to the area below the reflection base 1 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.

[0044] The present invention also proposes an antenna array, which includes at least two heat dissipation integrated antennas 100. The at least two heat dissipation integrated antennas 100 are arranged in sequence. In order to make the antenna array have a relatively compact size, the adjacent two heat dissipation integrated antennas 100 are arranged closely; among them, the specific structure of the heat dissipation integrated antenna 100 refers to the above-mentioned embodiments. Since this antenna array adopts all the technical solutions of the above-mentioned all embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be elaborated here one by one. Among them, referring to Figure 8 、 Figure 9 As shown, it is a schematic structural diagram of an antenna array composed of a heat dissipation integrated antenna 100 in one embodiment; in the length direction of the side plate 14, the air outlet cavity 142 penetrates through the side plate 14, so that a second outlet 42 is formed at each end of the side plate 14 in the length direction. In the arrangement direction of the second outlets 42, the air outlet cavities 142 in the adjacent two heat dissipation integrated antennas 100 are connected end to end to form an exhaust channel.

[0045] When the fan module 5 works, 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 outwards from the circumferential side surface of the antenna array through the exhaust channel formed by connecting the air outlet cavities 142 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, realizing a good cooling effect.

[0046] Referring to Figure 10 、 Figure 11As shown, it is a schematic diagram of the antenna array structure formed under another embodiment of the heat dissipation integrated antenna 100; 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, and 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.

[0047] When the fan module 5 is working, the cold air located on the periphery of 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 a better temperature reduction and cooling effect.

[0048] 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 reflective transverse plate 8, which is provided in plurality, and the plurality of reflective transverse plates 8 extend along the X direction, and the plurality of reflective transverse plates 8 are spaced apart along the Y direction; and a reflective longitudinal plate 9, which is provided in plurality, and the plurality of reflective longitudinal plates 9 extend 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 one 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.

[0049] In this embodiment, the reflective substrate 7 and the reflective transverse plate 8 and the reflective longitudinal plate 9 can be integrally arranged or separately arranged. The reflective transverse plate 8 and the reflective longitudinal plate 9 are staggered to enclose 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 staggered, 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.

[0050] 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 plate 14 adjacent to the air inlet cavity 141, because an air inlet cavity needs to be set in the side plate 14 opposite to the air inlet cavity 141, and the setting of the air inlet cavity makes it impossible to additionally set the air outlet cavity 142; alternatively, the position of the air outlet cavity 142 can also be set in the side plate 14 opposite to the air inlet cavity 141. At this time, in the side plate 14 opposite to the air inlet cavity 141, that is, in the thickness direction of the side plate 14, the sizes of the air outlet cavity 142 and the air inlet cavity 141 need to be compressed so that the air outlet cavity 142 and the air inlet cavity 141 can be set in the same side plate 14 at the same time.

[0051] In this embodiment, the materials of the reflection substrate 7, the reflection longitudinal plate 9 and the reflection transverse plate 8 are metals, such as copper; in this antenna array, the cover plate 2 can be one and is used to seal all the accommodation cavities 11, so as to provide a relatively sealed space for the antenna body 10; the cover plate 2 can also include sub-plates matching the number of the accommodation cavities 11, that is, each accommodation cavity 11 corresponds to a sub-plate, for achieving the sealing effect.

[0052] The above are only exemplary embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
