Description
Technical Field
[0001] This invention relates to the field of satellite antenna technology, and specifically to a backpack-style portable satellite antenna. Background Technology
[0002] Satellite antennas are key devices used to transmit and receive satellite signals. Common types include phased array antennas, parabolic antennas, and omnidirectional antennas.
[0003] A phased array antenna typically consists of an antenna, an antenna front-end processing unit, and a data processing unit, and is a highly integrated active device. The multi-functionality of a phased array antenna requires a higher output power from the antenna front-end processing unit and stronger processing capabilities from the data processing unit. This results in a generally high heat flux density, especially concentrated in the front-end processing unit, data processing unit, and power conversion module.
[0004] To enhance portability and control heat generation in phased array antennas, some existing portable phased array antennas neglect the heat generated by low-power devices in the antenna front-end processing unit, focusing only on cooling the high-power processing chips in the data processing unit. While this approach significantly reduces the overall size of the phased array radar antenna and improves portability, neglecting the heat generated by low-power devices severely limits the design of phased array radar antennas and restricts their operating environment, such as high ambient temperatures, thus affecting their versatility and reliability.
[0005] Therefore, how to effectively dissipate heat from phased array antennas, especially portable phased array antennas, more quickly is a technical problem that urgently needs to be solved in the industry. Summary of the Invention
[0006] This invention provides a backpack-style portable satellite antenna with good heat dissipation capabilities.
[0007] The present invention provides a backpack-style portable satellite antenna using the following technical solution:
[0008] A backpack-style portable satellite antenna includes an antenna body, a first heat sink and a second heat sink, the first heat sink being disposed on one side of the antenna body, and the second heat sink being slidably disposed on the first heat sink.
[0009] The first heat sink plate has an inlet channel and multiple water channels. A water container is connected to the inlet channel. The multiple water channels are all connected to the inlet channel. A one-way valve is installed in the inlet channel. The one-way valve is configured to allow water to flow from the inlet channel to the water channel only. The second heat sink plate has multiple heat sinks evenly arranged on the side opposite to the first heat sink plate. The multiple heat sinks form multiple heat dissipation cavities on the second heat sink plate through baffles. The multiple heat dissipation cavities correspond to multiple water channels. Water perforations are opened in the heat dissipation cavities. The water perforations are connected to the corresponding water channels. A one-way plug is installed on the water perforation. The one-way plug is a frustum-shaped rubber plug. The one-way plug is configured to be set and fixed on the sealing plate at the bottom of the heat dissipation cavity. The one-way plug faces the bottom of the heat dissipation cavity on the sealing plate and the small end of the one-way plug is inserted into the water perforation, while the large end of the one-way plug is located in the heat dissipation cavity.
[0010] The second heat sink is provided with multiple piston plates on the side facing the first heat sink. Each piston plate corresponds to a multiple heat sink cavity and is inserted into a multiple water channel. The piston plates are located on the side of the water inlet away from the water channel inlet. The piston plates are configured to slide in the corresponding water channel when the second heat sink slides, for the purpose of absorbing water from the water container.
[0011] It also includes a drive assembly that can move the second heat sink by pushing the heat sink. The drive assembly includes a rotating shaft, a reciprocating screw, a rotating wheel I, a rotating wheel II, a drive rope, and a drive motor. The rotating shaft is rotatably mounted on the outer frame of the antenna body, and the reciprocating screw is fixed on the outer frame. The rotating shaft and the reciprocating screw are located on both sides of the antenna body, respectively. The rotating wheel I is slidably mounted on the rotating shaft, and the rotating wheel II is slidably mounted on the reciprocating screw. The rotating wheels I and II correspond to each other. The drive rope is located inside the outer frame and is sleeved on the rotating wheel I, the rotating wheel II, the antenna body, and the second heat sink. The drive rope is configured to cooperate with the heat sink and can push the heat sink to move along an axial direction parallel to the rotating shaft. The drive motor is mounted on the outer frame and is used to drive the rotating shaft to rotate.
[0012] Furthermore, it also includes a base and a rotating support. The base has a rotating surface, and the rotating support is detachably mounted on the rotating surface. The rotating support has a U-shaped frame, and the antenna body is rotatably disposed within the U-shaped frame.
[0013] Furthermore, the first heat sink is provided with a limiting component for restricting the sliding of the second heat sink.
[0014] Furthermore, the limiting assembly includes a limiting rod and a limiting bolt. The limiting rod is fixed on the side of the first heat sink away from the antenna body, and a gap is left between the limiting rod and the first heat sink. The second heat sink is located between the two limiting rods and is in close contact with the first heat sink. Its two sides are respectively inserted into the gaps on the corresponding sides. The limiting bolt is installed at both ends of the limiting rod to limit the sliding range of the second heat sink on the first heat sink.
[0015] Furthermore, the heat sink is a continuous wave-shaped structure with crests and troughs. When the drive rope is looped on the heat sink, the drive rope is tensioned, and as the drive rope moves from the trough to the crest of the heat sink, the tension of the drive rope gradually increases.
[0016] Furthermore, the drive rope is a long strip-shaped structure with elasticity and water absorption.
[0017] Furthermore, the base includes a support base, support legs, and a turntable. The support legs are hinged to the support base, and the turntable is rotatably mounted on the support base. A rotary motor is provided on the support base, and the rotary motor drives the turntable to rotate. The rotary support is detachably mounted on the turntable.
[0018] Furthermore, a magnetic attraction structure and a snap-fit component are provided between the rotating support and the turntable.
[0019] The beneficial effects of this invention are:
[0020] The present invention provides a backpack portable satellite antenna, wherein a liquid inlet channel is provided on the first heat dissipation plate and is connected to an external water container, which can inject water into the channel. The water in the channel can liquid cool the antenna body, thereby accelerating the dissipation of heat transferred from the antenna body to the first heat dissipation plate. The driving component can drive the second heat dissipation plate to move on the first heat dissipation plate by pushing the heat sink, so that the contact area between the second heat dissipation plate and the first heat dissipation plate is larger, and the second heat dissipation plate can provide better heat dissipation effect on the first heat dissipation plate.
[0021] Simultaneously, when the second heat sink moves, the piston plate moves synchronously, thereby changing the size of the cavity between the piston plate and the top port of the water channel. When the cavity increases, the pressure inside the cavity decreases, and the cavity can draw water from the water container through the liquid inlet channel. When the cavity decreases, the pressure inside the cavity increases, and the high pressure can push the one-way plug away from the water permeable hole, thereby allowing the water inside the cavity to flow from the water permeable hole into the heat sink cavity.
[0022] When more water enters the cavity from the water container, the water can absorb more heat emitted by the antenna body, thereby improving the heat dissipation efficiency of the present invention. When water flows into the heat dissipation cavity from the water-permeable hole, the water can come into contact with the heat sink, thereby allowing the water to transfer heat to the heat sink, increasing the heat transfer area and further improving the heat dissipation efficiency of the present invention.
[0023] Furthermore, the antenna body can rotate within the U-shaped frame of the rotating support, which in turn can rotate on the base, thereby changing the orientation of the antenna body and facilitating interaction between the antenna body and terminal equipment such as satellites.
[0024] In addition, since the rotating bracket and the base are detachably connected, it is easier to remove the rotating bracket from the base, which improves the convenience of the invention.
[0025] Furthermore, the drive motor can drive the rotating shaft to rotate, the rotating shaft can drive the rotating wheel I to rotate, the rotating wheel I can drive the drive rope to rotate, the drive rope can drive the rotating wheel II to rotate, and the rotating wheel II can move back and forth on the reciprocating screw when it rotates, thereby driving the drive rope to slide back and forth in a direction parallel to the axis of the rotating shaft. When the drive rope moves back and forth axially, it can push the heat sink to move back and forth, thereby driving the second heat sink plate to move back and forth on the first heat sink plate through the heat sink plate, thereby making the second heat sink plate and the first heat sink plate have a larger contact area, which can improve the heat dissipation efficiency of the present invention.
[0026] In addition, the drive rope can not only slide over the front panel of the antenna body when it moves, but also over the heat dissipation cavity. When the drive rope slides over the heat dissipation cavity, it can absorb the water in the heat dissipation cavity, which can not only clean the front panel of the antenna body better, but also provide better heat dissipation effect for the front panel of the antenna body when the drive rope with water adsorbed slides over the front panel of the antenna body.
[0027] Furthermore, as the drive rope rotates around the heat sink, it not only dissipates heat and cleans the front panel of the antenna body, but also allows the heat sink to scrape off water and dust absorbed by the drive rope, thus maintaining its cleanliness. Attached Figure Description

[0042] like Figures 1 to 9 As shown in the figure, the present invention provides a backpack portable satellite antenna that can communicate with satellites or large-scale antennas. It includes an antenna body 100, a first heat sink 200 and a second heat sink 300.
[0043] The antenna body 100 is an existing phased array antenna. Its core principle is that multiple independent antenna elements are arranged into an array. The phase and amplitude of the transmitted / received signals of each element can be precisely controlled. Through the interference and superposition effect of electromagnetic waves in space, a high-gain beam is formed in a specified direction (focusing energy when transmitting and enhancing the signal when receiving). It can switch the scanning direction at a speed of microseconds or generate multiple beams at the same time.
[0044] The antenna body 100 has an outer frame 110, which can be a U-shaped frame fixed to the antenna body 100. Both the first heat sink 200 and the second heat sink 300 can be copper plates. The first heat sink 200 is mounted on one side of the antenna body 100 and is in contact with it. A heat-conducting sheet can be provided on the portion of the first heat sink 200 in contact with the antenna body 100 to improve the heat conduction efficiency of the first heat sink 200. The second heat sink 300 is slidably disposed on the side of the first heat sink 200 away from the antenna body 100. The second heat sink 300 and the first heat sink 200 can be in close contact.
[0045] The first heat sink 200 has a liquid inlet channel 210 and multiple water channels 220. The liquid inlet channel 210 is connected to a water container, and the multiple water channels 220 are all connected to the liquid inlet channel 210.
[0046] Specifically, the liquid inlet channel 210 can be a direct flow channel parallel to the sliding direction of the second heat sink 300. The liquid inlet channel 210 is opened inside the first heat sink 200 and close to one side of the first heat sink 200. A one-way valve is provided in the liquid inlet channel 210. The one-way valve is configured to allow water to flow from the liquid inlet channel 210 to the water flow channel 220 only.
[0047] The water flow channel 220 is a straight channel parallel to the liquid inlet channel 210 in its length direction, and the water flow channel 220 is directly connected to the outside. Multiple water flow channels 220 can be evenly divided into multiple rows on the first heat sink 200, with each row of multiple water flow channels 220 evenly distributed in a direction perpendicular to the liquid inlet channel 210. The first heat sink 200 also has intermediate flow channels, the number of which is equal to the number of rows of water flow channels 220. Each row of water flow channels 220 is connected to the liquid inlet channel 210 through an intermediate flow channel.
[0048] The second heat sink 300 has multiple heat sinks 310 on the side opposite to the first heat sink 200. These heat sinks 310 are evenly arranged along a sliding direction perpendicular to the second heat sink 300. The heat sinks 310 can be copper sheets, and their length direction is parallel to the sliding direction of the second heat sink 300. Multiple stop plates are fixed between adjacent heat sinks 310, and these stop plates are evenly distributed along the length direction of the heat sinks 310.
[0049] Multiple heat sinks 310, through multiple stop plates, can form multiple heat dissipation cavities 311 on the second heat dissipation plate 300. Each heat dissipation cavity 311 corresponds to multiple water flow channels 220. A water perforation hole 312 is provided within each heat dissipation cavity 311, communicating with the corresponding water flow channel 220. A one-way plug 313 is provided on each water perforation hole 312. The one-way plug 313 can be a frustum-shaped rubber plug, fixed to a sealing sheet of the same material. The sealing sheet is fixed to the bottom of the heat dissipation cavity 311, with the one-way plug 313 facing the bottom of the heat dissipation cavity 311. The smaller end of the one-way plug 313 is inserted into the water perforation hole 312, while the larger end of the one-way plug 313 is located within the heat dissipation cavity 311.
[0050] The second heat sink 300 has multiple piston plates 314 on the side facing the first heat sink 200. The multiple piston plates 314 correspond to multiple heat sink cavities 311 and are inserted into multiple water channels 220 respectively. The piston plates 314 are located on the side of the second heat sink 300 away from the inlet of the water channel 220 of the water permeable hole 312. The piston plates 314 are configured to slide in the corresponding water channel 220 when the second heat sink 300 slides on the first heat sink 200, for drawing water from the water container.
[0051] The present invention also includes a driving component, which can drive the second heat sink 300 to move on the first heat sink 200 by pushing the heat sink 310.
[0052] The operating principle of this invention is as follows:
[0053] First, a water container and the inlet of the liquid inlet channel 210 can be connected by a pipe. An electric pump can be installed on the pipe to drive the water in the water container to be transported into the liquid inlet channel 210. The water in the water container enters the intermediate channel through the liquid inlet channel 210, and then enters multiple water channels 220 through the intermediate channel.
[0054] The drive assembly can push the heat sink 310 to drive the second heat sink 300 to slide on the first heat sink 200. When the second heat sink 300 slides, it can drive the piston plate 314 to move. When the piston plate 314 moves, it can change the volume of the cavity formed between the piston plate 314 and the top port of the water channel 220. When the volume of the cavity between the piston plate 314 and the top port of the water channel 220 increases, the pressure in the cavity decreases, and water in the water container can be drawn into the corresponding cavity through the liquid inlet channel 210, the intermediate channel and the water channel 220. When the volume of the cavity between the piston plate 314 and the top port of the water channel 220 decreases, the pressure in the cavity increases. Since the liquid inlet channel 210 is equipped with a one-way valve, the water in the cavity can push the one-way plug 313 in the water permeable hole 312, and the water in the cavity can flow out from the water permeable hole 312 into the heat dissipation cavity 311.
[0055] When the water entering the liquid inlet channel 210 passes through the intermediate channel and the water channel 220, it can absorb the heat transferred from the antenna body 100 to the first heat sink 200, thereby playing a certain role in heat dissipation for the antenna body 100. Furthermore, when the water passes through the water permeable hole 312 and enters the heat dissipation cavity 311, it can contact the cavity wall of the heat dissipation cavity 311, thereby allowing the water to transfer heat to the heat sink 310, increasing the heat transfer area and further improving the heat dissipation efficiency of the present invention.
[0056] In this invention, water entering the heat dissipation cavity 311 will adhere to the heat dissipation fin 310 due to the surface tension of the water, making it difficult to flow out of the heat dissipation cavity 311. Only after the second heat dissipation plate 300 slides repeatedly on the first heat dissipation plate 200 can the water in the heat dissipation cavity 311 flow out. However, since the first heat dissipation plate 200 is spaced between the second heat dissipation plate 300 and the antenna body 100, the water cannot come into contact with the antenna body 100, so there is no need to worry about water entering the antenna body 100 and damaging it.
[0057] Furthermore, the present invention also includes a base 500 and a rotating support 600. The base 500 has a rotating surface, and the rotating support 600 is detachably mounted on the rotating surface. The rotating support 600 has a U-shaped frame 610, and the antenna body 100 is rotatably disposed within the U-shaped frame 610.
[0058] Specifically, the base 500 includes a support base 510, support legs 520, and a turntable 530. The support legs 520 can be telescopic rods with fixing components, such as fixing bolts or other structural components that can fix the length of the telescopic rod. Multiple support legs 520 can be provided, and these legs are evenly hinged to the support base 510 around its central axis. The turntable 530 is rotatably mounted on top of the support base 510. A rotary motor 511 is mounted on the bottom of the support base 510, and the output shaft of the rotary motor 511 passes through the support base 510 and is fixedly connected to the turntable 530, thereby driving the turntable 530 to rotate. The side of the turntable 530 away from the support base 510 is the rotation surface of the base 500.
[0059] The rotating support 600 is detachably mounted on the rotating surface, i.e., detachably mounted on the turntable 530. A magnetic attraction structure and a snap-fit mechanism are provided between the rotating support 600 and the turntable 530. The magnetic attraction structure can consist of two magnetic sheets, which are respectively fixed to the bottom surface of the rotating support 600 and the top surface of the turntable 530, with their opposing sides magnetically attracted to each other. The rotating support 600 is magnetically attached to the turntable 530 via the magnetic attraction structure.
[0060] The locking mechanism includes a locking slot and a locking rod. The locking slot is located on the turntable 530, and the locking rod is a flexible rod fixed to the rotating support 600, corresponding to the locking slot. The lower part of the locking rod has a wedge-shaped block, which engages the locking rod in the locking slot, thus locking the rotating support 600 onto the base 500. The upper part of the locking rod passes through the bottom plate of the rotating support 600. Moving the locking rod disengages the wedge-shaped block from the locking slot, thereby enabling a detachable connection between the rotating support 600 and the base 500.
[0061] The antenna body 100 can be mounted in a U-shaped frame 610 on a rotating support 600 via an adjustable knob, making it easier for operators to adjust the orientation of the antenna body 100. Alternatively, the antenna body 100 can be directly rotated between the two side supports of the U-shaped frame 610, with a control motor mounted on each support to adjust the rotation angle of the antenna body 100. Both the adjustable knob and the control motor allow for easier adjustment of the antenna body 100's rotation angle, facilitating data exchange with satellites or other large-scale antennas.
[0062] In addition, due to the detachable installation between the rotating support 600 and the base 500 in this embodiment, the rotating support 600 and the base 500 can be separated, which allows the present invention to be disassembled and stored. The disassembled base 500 and rotating support 600 can be stored in a backpack, making it more convenient to carry.
[0063] In some embodiments, the first heat sink 200 is provided with a limiting component for restricting the sliding range of the second heat sink 300. The limiting component includes a limiting rod 231 and a limiting bolt 232. There are two limiting rods 231, both of which are fixed to the side of the first heat sink 200 away from the antenna body 100, and the two limiting rods 231 are respectively located on both sides of the second heat sink 300. There is a gap between the limiting rods 231 and the first heat sink 200, and the two ends of the second heat sink 300 are respectively inserted into the gaps between the two limiting rods 231 and the first heat sink 200.
[0064] The limiting bolts 232 are installed at both ends of the limiting rod 231, so that when the first heat sink 200 slides on the second heat sink 300, it can only slide between the two limiting bolts 232.
[0065] The limiting rod 231 can limit the second heat sink 300 in the direction perpendicular to the sliding of the second heat sink 300 and can make the second heat sink 300 in close contact with the first heat sink 200. The limiting bolt 232 can limit the second heat sink 300 in the sliding direction of the second heat sink 300.
[0066] The setting of the limiting component allows the second heat sink 300 to fit more tightly with the first heat sink 200, so that when water flows in the water channel 220, it will not flow everywhere due to the possible gap between the first heat sink 200 and the second heat sink 300, thereby affecting the sealing of the water flow in the water channel 220. This allows the water to better transfer the heat emitted by the antenna body 100, resulting in a better heat dissipation effect for the present invention.
[0067] In some embodiments, the drive assembly includes a rotating shaft 410, a reciprocating lead screw 420, a rotating wheel I 430, a rotating wheel II 440, a drive rope 450, and a drive motor 460. The rotating shaft 410 is rotatably mounted on the outer frame 110, and the reciprocating lead screw 420 is fixed on the outer frame 110. The rotating shaft 410 and the reciprocating lead screw 420 are located on opposite sides of the antenna body 100. The rotating wheel I 430 is slidably mounted on the rotating shaft 410, and the rotating wheel II 440 is slidably mounted on the reciprocating lead screw 420. The rotating wheels I 430 and II 440 are located on the same horizontal plane and correspond to each other.
[0068] The rotating shaft 410 is a long straight rod with an axial groove on its side wall, and the rotating wheel I 430 is a circular wheel with an axial protrusion fixed on its inner side wall. When the rotating wheel I 430 is sleeved on the rotating shaft 410, the axial protrusion is located in the axial groove. When the rotating shaft 410 rotates, it can drive the rotating wheel I 430 to rotate.
[0069] The reciprocating lead screw 420 can be an existing straight rod consisting of two threaded grooves with the same pitch and opposite directions connected by a transition curve. The rotating wheel II 440 is a circular wheel adapted to the reciprocating lead screw 420. When the rotating wheel II 440 rotates on the reciprocating lead screw 420, and when the rotating wheel II 440 moves to the top and bottom ends of the reciprocating lead screw 420, the rotating wheel II 440 can achieve automatic reversal.
[0070] Both rotating wheels I 430 and II 440 have annular grooves. The drive rope 450 is located inside the outer frame 110 and is sleeved on rotating wheels I 430, II 440, the antenna body 100, and the second heat sink 300. When the drive rope 450 is on rotating wheels I 430 and II 440, it is located at the corresponding groove.
[0071] The drive rope 450 is configured to cooperate with the heat sink 310, enabling it to move the heat sink 310 in a direction parallel to the rotating shaft 410. The drive motor 460 is mounted on the outer frame 110, and the output shaft of the drive motor 460 is fixedly connected to the rotating shaft 410. When the drive motor 460 is running, it can drive the rotating wheel I 430 to rotate via the rotating shaft 410. When the rotating wheel I 430 rotates, it can drive the drive rope 450 to rotate. When the drive rope 450 rotates, it can drive the rotating wheel II 440 to rotate. When the rotating wheel II 440 rotates, it can move on the reciprocating screw 420, thereby causing the drive rope 450 to slide on the heat sink 310. When the drive rope 450 slides on the heat sink 310, it can push the heat sink 310 to move in a direction parallel to the rotating shaft 410.
[0072] When the rotating wheel II 440 moves on the reciprocating screw 420, it can slide back and forth in its axial direction, realizing the reciprocating sliding of the drive rope 450 in the direction parallel to the rotating shaft 410. This can drive the heat sink 310 and the second heat sink 300 to slide back and forth on the first heat sink 200, so that the contact area between the second heat sink 300 and the first heat sink 200 is larger, which can improve the heat dissipation efficiency of the second heat sink 300 on the first heat sink 200, improve the heat dissipation efficiency of the present invention, and help the antenna body 100 dissipate heat.
[0073] Furthermore, the heat sink 310 is a continuous wave-shaped structure. The heat sink 310 has crests and troughs. When the drive rope 450 is sleeved on the heat sink 310, the drive rope 450 is tensioned, and the tension varies at different positions on the heat sink 310. Specifically, the tension of the drive rope 450 is greatest when it is located at a crest of the heat sink 310, and least when it is located at a trough. Driven by the rotating wheel II 440, the drive rope 450 can move from the trough to the crest of the heat sink 310. During this movement, the tension of the drive rope 450 gradually increases from minimum to maximum.
[0074] When the drive rope 450 moves on the heat sink 310, the tensioned drive rope 450 can push the heat sink 310 to move. In particular, during the process of the drive rope 450 moving from the trough to the crest of the heat sink 310, the drive rope 450 can provide the maximum thrust to the heat sink 310, which can realize the sliding of the second heat sink 300 on the first heat sink 200.
[0075] The sliding of the second heat sink 300 on the first heat sink 200 allows the second heat sink 300 to have a larger contact area with the first heat sink 200, thereby improving the heat dissipation efficiency of the present invention.
[0076] Furthermore, the drive rope 450 is a long strip structure with elasticity and water absorption, specifically a composite fiber cotton rope.
[0077] In this embodiment, the drive rope 450 can slide on the antenna body 100 under the drive of the rotating wheel I 430 and the rotating wheel II 440. Since the rotating wheel I 430 can rotate under the drive of the drive motor 460 and the rotating shaft 410, the drive rope 450 can also rotate during the movement. The rotating drive rope 450 can pass through the heat dissipation cavity 311 and thus absorb the water in the heat dissipation cavity 311.
[0078] When the drive rope 450 moves on the antenna body 100, it can slide over the front panel of the antenna body 100, thereby wiping and cleaning the front panel of the antenna body 100 during the sliding process. At the same time, since the drive rope 450 absorbs some of the water in the heat dissipation cavity 311 when it passes through the heat dissipation cavity 311, the drive rope 450 can also dissipate heat from the antenna body 100 during the wiping process.
[0079] In addition, when the drive rope 450 rotates around the antenna body 100, especially when it passes the heat sink 310, the dust that sticks to the drive rope 450 as it slides over the antenna body 100 can be scraped off by the heat sink 310, thereby cleaning the drive rope 450 and ensuring its cleanliness. This allows the drive rope 450 to absorb water from the heat dissipation cavity 311 in a timely manner, so as to better dissipate heat from the front panel of the antenna body 100.
[0080] In this embodiment, when the drive rope 450 wipes and cleans the front panel of the antenna body 100, it can be done when the antenna body 100 is not working, so as to avoid adverse effects on the operation of the antenna body 100 caused by the drive rope 450 passing through the interaction surface of the antenna body 100.
[0081] Of course, if the antenna body 100 overheats, the drive motor 460 can be turned on in a timely manner, allowing the drive rope 450 to slide over the antenna body 100 and dissipate heat in time. Compared to wiping the front panel (interaction surface) of the antenna body 100 directly with a wet wipe, the drive rope 450 has less impact on the antenna body 100 when it passes over the front panel.
[0082] In some other embodiments, a cooling fan may also be installed on the outer frame 110 of the antenna body 100. The cooling fan is located on the side of the heat sink 310 away from the second heat sink 300. The cooling fan can improve the heat dissipation efficiency of the antenna body 100 in this invention.
[0083] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
