Abstract
Description
Technical Field
[0001] This utility model relates to the field of power amplifier technology, and in particular to a radio power amplifier. Background Technology
[0002] In the field of radio communication, power amplifiers, as core components, undertake the crucial task of signal amplification. With the rapid development of communication technology, radio power amplifiers are constantly evolving towards higher power, miniaturization, and integration, which makes their heat dissipation problems increasingly prominent.
[0003] Currently, common heat dissipation methods for radio power amplifiers mainly rely on traditional heat sinks and fixed-size heat dissipation structures. Traditional heat sinks have a fixed size and shape design, and their heat dissipation area cannot be changed after manufacturing. However, in practical applications, the operating state of radio power amplifiers is not static; their power output is dynamically adjusted according to communication needs. Power requirements can vary significantly in different application scenarios or operating modes. For example, in mobile communication base stations, during peak daytime traffic, the power amplifier needs to operate at full load with a high output power; while at night, when traffic decreases, the output power decreases accordingly. When the power amplifier is operating at low power, a fixed-size heat sink often wastes heat dissipation resources and increases unnecessary energy consumption. Conversely, when the power amplifier is operating at full load and generating a large amount of heat, a fixed-size heat sink may not be able to meet the heat dissipation requirements, causing the power amplifier's operating temperature to rise, thus affecting its performance and reliability.
[0004] Therefore, it is necessary to provide a new radio power amplifier to solve the above-mentioned technical problems. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a radio power amplifier.
[0006] The radio power amplifier provided by this utility model includes: an amplifier body, wherein mounting grooves are formed by inward recesses on opposite sides of the amplifier body, a heat dissipation component with adjustable heat dissipation size is provided on the surface of the mounting groove, and a limiting component for limiting its sliding distance is also provided on the surface of the heat dissipation component.
[0007] Preferably, the heat dissipation assembly includes a telescopic member, a heat dissipation cloth, and a slider. The two ends of the slider slide on the inner wall of the mounting groove. A pull ring is fixed on the surface of the slider. One end of the telescopic member is fixedly connected to the inner wall of the mounting groove. One side of the slider is fixedly connected to the other end of the telescopic member. The two ends of the heat dissipation cloth are respectively fixedly connected to the end of the slider away from the telescopic member and the inner wall of the mounting groove.
[0008] Preferably, the telescopic component includes a fixed plate, multiple springs, and a movable plate. The movable plate extends and retracts at one end of the fixed plate. The fixed plate is fixed to the inner wall of the mounting groove. The multiple springs are located inside the fixed plate, and both ends of the multiple springs are fixedly connected to the mounting groove and one end of the movable plate, respectively. The other end of the movable plate is fixedly connected to one side of the slider.
[0009] Preferably, the slider is provided with slots at both ends, the limiting component includes two mounting plates, the two mounting plates are located on opposite sides of the mounting slot, the surface of the mounting plates is provided with multiple positioning holes, each of the multiple positioning holes is threaded with a screw, and one end of one of the screws is inserted into the slot.
[0010] Preferably, the heat dissipation cloth includes two metal wire meshes and a soft cotton layer sandwiched between the two metal wire meshes. The two ends of the two metal wire meshes and the soft cotton layer are respectively fixedly connected to the end of the slider away from the movable plate and the inner wall of the mounting groove.
[0011] Preferably, the amplifier body is further provided with an input port, a display screen, buttons, knobs and a power socket on its outer side.
[0012] Compared with related technologies, the wireless power amplifier provided by this utility model has the following advantages:
[0013] 1. The wireless power amplifier of this utility model, by setting mounting slots on opposite sides of the amplifier body and equipping the surface of the mounting slots with adjustable heat dissipation components, can adapt to the dynamic heat dissipation requirements of the power amplifier under different operating conditions. In practical applications, such as mobile communication base stations, during peak daytime traffic, the power amplifier operates at full load with high output power. At this time, the adjustable heat dissipation components can increase the heat dissipation size and area, quickly and effectively dissipating a large amount of heat and preventing the power amplifier from overheating, which could lead to performance degradation or even damage. Conversely, at night when traffic decreases and output power is reduced, the heat dissipation components can decrease in size, avoiding waste of heat dissipation resources and reducing unnecessary energy consumption.
[0014] 2. By equipping the surface of the heat dissipation component with a limiting component, the sliding distance of the heat dissipation component can be limited, ensuring the accuracy of the size adjustment of the heat dissipation component during the adjustment process and making it more stable after adjustment.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0022] Please refer to the following: Figures 1 to 5 ,in, Figure 1 A schematic diagram of the overall structure of the radio power amplifier provided by this utility model; Figure 2 A cross-sectional structural diagram of the radio power amplifier provided by this utility model; Figure 3 This is a schematic diagram of the heat dissipation component. Figure 4 This is a structural diagram of the heat dissipation component. Figure 5 This is a breakdown diagram of the heat dissipation component.
[0023] In some embodiments, reference is made to Figures 1 to 5 As shown, the amplifier body 1 is provided with mounting grooves 2 formed by inward recesses on opposite sides of the amplifier body 1. The surface of the mounting groove 2 is provided with a heat dissipation component with adjustable heat dissipation size, and the surface of the heat dissipation component is also equipped with a limiting component for limiting its sliding distance.
[0024] The heat dissipation assembly includes a telescopic component, a heat dissipation cloth 23, and a slider 231. The two ends of the slider 231 slide on the inner wall of the mounting groove 2, that is, the inner wall of the mounting groove 2 has a groove, and the two ends of the slider 231 slide in the groove so that the slider 231 will not detach from the mounting groove 2 when sliding. A pull ring 232 is fixed on the surface of the slider 231. One end of the telescopic component is fixedly connected to the inner wall of the mounting groove 2, one side of the slider 231 is fixedly connected to the other end of the telescopic component, and the two ends of the heat dissipation cloth 23 are fixedly connected to the end of the slider 231 away from the telescopic component and the inner wall of the mounting groove 2, respectively.
[0025] The telescopic component includes a fixed plate 21, multiple springs 211, and a movable plate 22. The movable plate 22 extends and retracts at one end of the fixed plate 21. The fixed plate 21 is fixed to the inner wall of the mounting groove 2. The multiple springs 211 are located inside the fixed plate 21, and the two ends of the multiple springs 211 are respectively fixedly connected to the mounting groove 2 and one end of the movable plate 22. The other end of the movable plate 22 is fixedly connected to one side of the slider 231.
[0026] The slider 231 has slots 2313 at both ends. The limiting component includes two mounting plates 24. The bottom of the mounting plates 24 is connected to the groove. The two mounting plates 24 are fixed on opposite sides of the amplifier body 1. The two mounting plates 24 are located on both sides of the mounting groove 2. The surface of the mounting plates 24 is provided with multiple positioning holes. Each of the multiple positioning holes is threaded with a screw 241, and one end of one of the screws 241 is inserted into the slot 2313.
[0027] Specifically, in practical applications, such as mobile communication base stations, the power amplifier operates at full load and outputs high power during peak daytime call volume. When in use, first, hold the pull ring 232 to pull the slider 231, pushing the movable plate 22 to extend and retract at one end of the fixed plate 21. At this time, multiple springs 211 undergo elastic deformation and contraction. Then, tighten multiple screws 241. Since the screws 241 are threadedly connected to the positioning holes, one end of one of the screws 241 passes through the surface of the mounting plate 24 and is inserted into the slot 2313, thus limiting the sliding position, increasing the heat dissipation area, and quickly and effectively dissipating a large amount of heat, preventing the power amplifier body 1 from degrading or even being damaged due to overheating.
[0028] When call volume decreases and output power is reduced at night, the heat dissipation component can be made smaller. At this time, screwing screw 241 will remove one end from the slot 2313, thus releasing the restriction on slider 231. Sliding slider 231 will shorten the size of heat dissipation cloth 23, that is, adjust its length. Then screwing screw 241 will allow one end to be inserted back into the slot 2313, thus avoiding waste of heat dissipation resources and reducing unnecessary energy consumption.
[0029] In some embodiments, reference is made to Figure 1 , Figure 4 as well as Figure 5 As shown, the heat dissipation cloth 23 includes two metal wire meshes 2311 and a soft cotton layer 2312 sandwiched between the two metal wire meshes 2311. The two ends of the two metal wire meshes 2311 and the soft cotton layer 2312 are respectively fixedly connected to the end of the slider 231 away from the movable plate 22 and the inner wall of the mounting groove 2.
[0030] The main function of the soft cotton layer 2312 is to reduce the entry of external moisture into the amplifier body 1, which would affect the use of the power amplifier. In addition, the soft cotton layer 2312 has a porous structure, in which air can circulate.
[0031] Specifically, the metal mesh 2311 has good thermal conductivity, which can quickly conduct the heat generated by the power amplifier to the entire heat dissipation cloth 23. When the power amplifier is working, the heat generated is first absorbed by the metal mesh 2311 and then quickly dissipated along the mesh openings of the metal mesh 2311.
[0032] In some embodiments, reference is made to Figure 1 As shown, the amplifier body 1 is also equipped with an input port 11, a display screen 12, a button 13, a knob 14 and a power socket 15 on its outer side.
[0033] Specifically, input port 11 is used to receive signals from external signal sources. It is the entry point for signals into the power amplifier. The interface types include BNC interface, SMA interface, etc., to adapt to different types of signal transmission requirements.
[0034] The display screen 12 shows the user various operating parameters and status information of the power amplifier, such as the current output power, operating frequency, temperature, etc.
[0035] Button 13 and knob 14, as important tools for human-computer interaction, are located on the outside of the amplifier body 1 in an easily accessible position. Button 13 can realize some simple function switching, such as turning the power amplifier on or off, selecting different working modes, etc.; knob 14 is used to finely adjust certain parameters of the power amplifier, including adjusting the output power or adjusting the working frequency, etc.
[0036] Power socket 15 is used to connect an external power supply device. The type of power socket 15 is such as an AC power interface.
[0037] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
