Description

Technical Field

[0001] This disclosure relates to the field of antenna heat dissipation technology, and specifically to a heat dissipation device for an airborne antenna and an airborne antenna. Background Technology

[0002] Airborne antennas generate significant heat, and natural cooling is insufficient to meet the requirements, necessitating auxiliary cooling measures. Since airborne antennas are mounted outside the moving vehicle, cooling needs to be addressed both during stationary and mobile operation. Currently known cooling solutions include dual-duct or composite duct designs. For example, Patent 1 (Application No. CN202320338169.2) proposes a cooling device for airborne antennas that automatically switches cooling ducts under various conditions by introducing three movable baffles, ensuring adequate overall cooling. Patent 2 (Application No. CN202510049137.4) proposes a wind-cooled phased array antenna suitable for airborne satellite communication. It constructs a dual-layer cooling system and automatic dampers by introducing duct partitions and wind deflectors hinged to the partitions near the fan, addressing the cooling needs of both airborne and ground-based operation. It is evident that the three movable baffles and automatic dampers in these two heat dissipation schemes are all moving parts with rotating shafts. During long-term vibration, the rotating shafts are prone to wear and jamming. In addition, the baffle structures in these two heat dissipation schemes are complex, large in size, and occupy space, especially in height, which is not conducive to the miniaturization of the whole machine.

[0022] See Figures 1-5 This disclosure discloses an airborne antenna 10 and a heat dissipation device 100 for the airborne antenna. "Airborne" generally refers to an antenna carried by a mobile vehicle, examples of which include, but are not limited to, aircraft, high-speed trains, and other means of transportation. The airborne antenna 10 includes an antenna component (not shown), a heat dissipation device 100, and an airborne antenna housing 101. The heat dissipation device 100 includes a heat dissipation cavity 110, at least one fan 120, at least one fixed air guide plate 130, and heat dissipation fins 140. The heat dissipation cavity 110 defines a heat dissipation airflow channel for heat dissipation airflow, the heat dissipation airflow channel including an airflow inlet 150 and an airflow outlet 160 opposite to the airflow inlet 150. One or more openings are provided on the airborne antenna housing 101 at positions corresponding to the airflow inlet 150 and airflow outlet 160 of the heat dissipation airflow channel, such as... Figure 2Multiple rectangular through holes 1010 are shown. At least one fan 120 is disposed within the heat dissipation duct, between the airflow inlet 150 and the airflow outlet 160. At least one fixed guide plate is disposed on the side of the at least one fan 120 facing the airflow inlet and spatially spaced from the at least one fan 120. Heat dissipation fins 140 are disposed within the heat dissipation duct, between the airflow inlet and the airflow outlet. The heat dissipation fins 140 are thermally coupled to the antenna component (not shown) carried by the heat dissipation cavity 110 to dissipate the heat generated by the antenna component during operation. In the illustrated embodiment, the heat dissipation fins 140 are located on the side of the at least one fan 120 opposite to the airflow inlet. The heat dissipation device proposed in this disclosure dissipates heat from the airborne antenna by introducing a fixed guide plate. Since the fixed guide plate has no extra moving parts, compared with the method of introducing a movable baffle in the currently known heat dissipation scheme, there is no risk of easy wear and jamming of the rotating shaft. In addition, the fixed guide plate has a simple structure and saves space. Compared with the known dual-duct design and composite duct design, it is beneficial to reduce the overall height of the heat dissipation device.

[0023] In some embodiments, the fixed deflector 130 is configured to guide airflow that encounters the cooling duct when the mobile vehicle is in motion to at least partially bypass the fan 120. For this purpose, the fixed deflector 130 can have any suitable aerodynamic shape to guide the airflow direction. Advantageously, this can also reduce the drag of the airborne antenna and improve the fuel economy of the mobile vehicle. In some embodiments, each of at least one fixed deflector 130 can be an opening structure comprising a closed tip and extending outwards from the closed tip, with the opening of the opening structure facing the corresponding fan. It should be noted that the fixed deflector 130 shown in the figures is merely schematic, and the shape of the fixed deflector 130 is not limited to the inverted "V" shape shown, but may also include conical shapes, pyramidal shapes, etc.

[0024] When the mobile vehicle is in a parked state (e.g.) Figure 4 When the fan 120 is powered on and rotates, it draws in external air from the airflow inlet to form a cooling airflow. Because the fixed guide plate 130 and the fan 120 are spatially separated, the rotation of the fan 120 creates a localized low pressure in the space between them, drawing air in from the outside and causing it to flow over the cooling fins 140 to dissipate heat from the antenna components (not shown). When the mobile vehicle is in a moving state (e.g., ...), Figure 5 As shown, when the fan is in flight, the air in front of it crashes into the cooling duct and forms a cooling airflow, so the fan can dissipate heat without being powered on. Since the fixed guide plate 130 is located in front of the fan 120, it can reduce the chance of the fan 120 being passively rotated due to the impact of high-speed airflow (including sand, water vapor, etc.) on the blades of the fan 120, thereby delaying fan wear and extending the fan's life.

[0025] The heat dissipation device proposed in this embodiment guides the airflow that is hitting the heat dissipation duct to at least partially bypass the fan when the mobile vehicle is in a moving state by introducing a fixed guide plate; when the mobile vehicle is in a stationary state, the fan is powered on and rotates, drawing external air into the heat dissipation duct from the airflow inlet to form a heat dissipation airflow, thus taking into account the heat dissipation needs of the airborne antenna when stationary and when moving.

[0026] In some embodiments, the heat dissipation cavity 110 can be stacked and assembled with the heat dissipation cavity cover 170, and then installed together with the airborne antenna housing 101 onto a mobile vehicle, for example, onto the top of the mobile vehicle's fuselage, so that the antenna components carried by the heat dissipation cavity 110 can receive and transmit signals to the sky. It will be understood that the heat dissipation cavity cover 170 is not essential and can be omitted in some cases. For example, the heat dissipation cavity 110, together with the airborne antenna housing 101, can be directly installed onto the top of the mobile vehicle's fuselage, with the outer wall of the top of the mobile vehicle's fuselage serving as the heat dissipation cavity cover 170.

[0027] In some embodiments, at least a portion of the fixed guide plate 130 may extend over the entire height of the heat dissipation duct. In the illustrated embodiment, at least a portion of the fixed guide plate 130 may extend from the inner wall of the top of the heat dissipation cavity 110 (facing the airborne antenna housing 101) to the heat dissipation cavity cover plate 170, or from the heat dissipation cavity cover plate 170 to the inner wall of the top of the heat dissipation cavity 110. This can increase the cross-sectional area of ​​the fixed guide plate 130 and reduce the chance of high-speed airflow impacting the fan 120. In the illustrated embodiment, the fixed guide plate 130 may be fixed to the inner wall of the top of the heat dissipation cavity 110 and extend toward the heat dissipation cavity cover plate 170; or it may be fixed to the heat dissipation cavity cover plate 170 and extend toward the inner wall of the top of the heat dissipation cavity 110. Similarly, the fan 120 may be fixed to the inner wall of the top of the heat dissipation cavity 110 or to the heat dissipation cavity cover plate 170.

[0028] When multiple fans 120 are present, the fans 120 can be spatially spaced apart from each other in the width direction of the heat dissipation duct, with gaps between adjacent fans allowing airflow to pass through. This allows airflow to flow smoothly through the heat dissipation channel, improving heat dissipation efficiency. Alternatively, the multiple fans 120 can be arranged side-by-side in the width direction of the heat dissipation duct, with no gaps between adjacent fans. For example, the multiple fans 120 can be assembled as a single unit, close together. This reduces the amount of work required to install the fans into the heat dissipation duct.

[0029] Furthermore, when multiple fans 120 are present, a corresponding fixed guide vane 130 can be provided on the side of each fan 120 facing the airflow inlet. In other words, multiple fans 120 correspond one-to-one with multiple fixed guide vanes 130. Alternatively, two or more of the multiple fans 120 can share the same fixed guide vane 130. With multiple fixed guide vanes 130, the multiple fixed guide vanes 130 can be spatially spaced from each other in the width direction of the heat dissipation channel, so that the airflow can flow smoothly through the heat dissipation channel and improve the heat dissipation effect.

[0030] In some embodiments, the shortest distance between each of the at least one fixed guide vane 130 and the corresponding fan is the dimension of a fan in the length direction of the heat dissipation duct.

[0031] In some embodiments, a plurality of fans 120 are spatially spaced apart from each other in the width direction of the heat dissipation duct, and there are gaps between adjacent fans for airflow to pass through. Each of the plurality of fans 120 is provided with a guide plate 180 arranged side by side on both sides of the width direction of the heat dissipation duct, and there is a gap between each guide plate 180 and the corresponding fixed guide plate 130 for airflow to pass through.

[0032] In some embodiments, the shortest distance between each guide vane 180 and the corresponding fixed guide vane 130 is half the length of a fan in the heat dissipation duct.

[0033] exist Figure 1 and Figures 3-5 In the illustrated embodiment, the airflow inlet of the cooling duct is shown as comprising multiple branch channels that are in air communication with the main airflow section of the cooling duct, and the centerlines of the branch channels each form an angle with the centerline of the main airflow section. Thus, when the mobile vehicle is in motion, the oncoming wind in the forward direction impacts the inner wall of the branch channels before entering the main airflow section of the cooling duct, thereby reducing the speed of the oncoming wind entering the main airflow section and further protecting the fan 120 from impact by high-speed airflow. It should be understood that the two branch channels shown in the figure are merely schematic; in other embodiments, the airflow inlet of the cooling duct may include more or fewer branch channels. In some embodiments, the airflow inlet of the cooling duct may not include branch channels and may instead be directly formed as an opening at one end of the main airflow section of the cooling duct.

[0034] exist Figures 1-5In the illustrated embodiment, the opening on the airborne antenna housing 101 corresponding to the airflow inlet of the cooling duct includes one or more through holes, and the airflow inlet of the cooling duct does not extend beyond the airborne antenna housing 101. In this embodiment, airflow flows through the one or more through holes on the airborne antenna housing 101 and then enters the cooling duct via the airflow inlet. Alternatively, the opening on the airborne antenna housing 101 corresponding to the airflow inlet of the cooling duct can be configured to allow the airflow inlet of the cooling duct to pass through, and the airflow inlet of the cooling duct extends beyond the airborne antenna housing 101. In this embodiment, airflow enters the cooling duct directly via the airflow inlet of the cooling duct.

[0035] exist Figure 1 and Figures 3-5 In the illustrated embodiment, the fan 120 and the corresponding fixed guide plate 130 are disposed in the heat dissipation duct, closer to the airflow inlet than to the airflow outlet. Alternatively, the fan 120 and the corresponding fixed guide plate 130 may be disposed in the heat dissipation duct, closer to the airflow outlet than to the airflow inlet. In such an embodiment, the heat dissipation fins 140 should be disposed on the side of the fan 120 facing the airflow inlet, and the side of the fan 120 facing away from the airflow inlet may or may not have additional heat dissipation fins 190.

[0036] exist Figure 1 and Figures 3-5 In the embodiment shown, the fan 120 and the corresponding fixed guide plate 130 are disposed in the heat dissipation duct, which is closer to the air inlet than to the air outlet, and additional heat dissipation fins 190 are provided on the side of the fixed guide plate 130 facing the air inlet.

[0037] The additional heat dissipation fins 190 can improve heat dissipation. Furthermore, the additional heat dissipation fins 190 can be configured to guide the airflow that enters the cooling duct head-on when the mobile vehicle is moving, so that it impacts the fixed guide plate 130 from the front. For example, the additional heat dissipation fins 190 can be arranged to extend along a direction parallel to the centerline of the cooling duct. This provides the following beneficial effects: when the mobile vehicle is moving, the high-speed airflow entering the cooling duct from the airflow inlet is likely to have a scattered flow direction, thus easily penetrating the space between the fixed guide plate 130 and the fan 120 and passing through the fan 120, thereby causing the fan 120 to passively rotate; by rectifying the flow direction of the airflow entering the cooling duct with the additional heat dissipation fins 190, the chance of the high-speed airflow penetrating the space between the fixed guide plate 130 and the fan 120 and impacting the fan 120 can be reduced. The additional heat dissipation fins 8 can be separate from the fixed guide plate 130 or integrally formed with it. When the additional heat dissipation fins 190 and the fixed airflow guide plate 130 are integrally formed, the integrally formed structure serves both the functions of heat dissipation and airflow guidance.

[0038] In some embodiments, the additional heat dissipation fins 190 include a plurality of additional heat dissipation fins arranged side-by-side at intervals along the width direction of the heat dissipation duct. Among the plurality of additional heat dissipation fins is a target additional heat dissipation fin, the shortest distance from the end of the target additional heat dissipation fin facing the airflow outlet to the corresponding fixed guide plate being half the dimension of a fan in the length direction of the heat dissipation duct. The edge of the corresponding fixed guide plate in the width direction of the heat dissipation duct lies on the extension line of the target additional heat dissipation fin extending along the length direction of the heat dissipation duct. Exemplarily, the target additional heat dissipation fin can be as follows: Figure 5 The first target is equipped with heat dissipation fin 1901 and the second target is equipped with heat dissipation fin 1902.

[0039] It is understandable that when multiple fans 120 are spatially spaced apart in the width direction of the heat dissipation duct, and each fan 120 corresponds to a fixed air guide plate 130, each fixed air guide plate 130 has multiple additional heat dissipation fins, and correspondingly, each fixed air guide plate has a target additional heat dissipation fin. For example... Figure 5 As shown, the six additional heat dissipation fins in region 1903 correspond to the leftmost fixed air guide plate, and the corresponding target additional heat dissipation fins include the first target additional heat dissipation fin 1901 and the second target additional heat dissipation fin 1902.
