Although traditional power amplifiers, such as traveling-wave tube amplifiers and klystron amplifiers, meet the demand to a certain extent, they have disadvantages such as large volume, heavy weight, high power consumption, and high maintenance cost. Therefore, solid-state power amplifiers, as a new type of high-frequency power amplifier, have emerged. When designing a solid-state power amplifier unit component, it is necessary to ensure that the temperature of the core power device cannot be too high; the space volume cannot be too large and the weight cannot be too heavy, otherwise it will cause inconvenience in installation and maintenance.

[0003] After retrieval, the Chinese patent document application number: 202020740383.7 discloses a solid-state power amplifier unit component, including a front panel, a rear panel, an upper unit case, a lower unit case, a left unit case, a right unit case, and a welded heat sink fin radiator. The front panel, rear panel, upper unit case, lower unit case, left unit case, and right unit case form a square structure. The welded heat sink fin radiator is located inside the square structure. Shielding boxes are installed on both the front and back sides of the welded heat sink fin radiator. A plurality of solid-state power tubes are evenly installed inside the shielding boxes.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-5, the present utility model provides a technical solution: a solid-state power amplifier unit assembly, including a power amplifier box body 1, a ventilation plate 9 is installed on the surface of the power amplifier box body 1, a plurality of heat dissipation holes 10 are opened on the surface of the ventilation plate 9, ventilation holes 4 are opened on both sides of the power amplifier box body 1, a cover plate 2 is arranged at the top of the power amplifier box body 1, first threaded holes 203 are opened on the peripheral surface of the cover plate 2, a hand-tightening screw 202 is threadedly installed on the inner wall of the first threaded holes 203, limiting strips 204 are fixedly installed on the outer walls on both sides of the cover plate 2, and limiting grooves 205 for the limiting strips 204 to move are opened on the inner walls on both sides at the top of the power amplifier box body 1. Fixing plates 11 are installed on both sides at the top of the power amplifier box body 1, second threaded holes 208 are opened on the surfaces on both sides of the two fixing plates 11, and one end of the hand-tightening screw 202 is threadedly installed on the inner wall of the second threaded holes 208;

[0024] During use, the limiting strips 204 fixedly installed on the outer walls on both sides of the cover plate 2 cooperate with the limiting grooves 205 on the inner walls on both sides at the top of the power amplifier box body 1, which not only enhances the stability of the cover plate 2 during installation, but also plays a guiding role during the disassembly process, ensuring that the cover plate 2 can be smoothly and safely detached from the box body, avoiding damage or accidental movement of internal components caused by direct disassembly. The plurality of heat dissipation holes 10 opened on the surface of the ventilation plate 9 not only contribute to the heat dissipation of the power amplifier unit, but also provide a channel for the discharge of dust.

[0025] An anti-slip layer 201 is installed on the surface of the cover plate 2, and the anti-slip layer 201 is arranged in a corrugated shape. Compared with a flat layer, the corrugated anti-slip layer 201 can increase the friction with the sole or the contact surface, thereby effectively preventing slipping.

[0026] One end of the cover plate 2 is fixedly installed with a clamping block 206, a clamping groove 207 is opened on one side of the surface of the power amplifier box body 1, and one end of the clamping block 206 is clamped inside the clamping groove 207. The close cooperation between the clamping block 206 and the clamping groove 207 can ensure that the cover plate 2 remains stable and does not shake during use, thereby avoiding potential safety hazards caused by the loosening of the cover plate 2.

[0027] Air outlets are opened on both sides of the surface of the power amplifier box body 1, and a heat dissipation component is arranged inside the air outlets. The heat dissipation component includes a driving motor 17, a support frame 18 and a fan blade 19. The periphery of the support frame 18 is fixedly installed on the side wall of the air outlet, the base of the driving motor 17 is fixedly installed on the side wall of the support frame 18, the output shaft of the driving motor 17 passes through the side wall of the support frame 18 and is fixedly connected to the rotating shaft of the fan blade 19. A fan baffle 5 is installed on the outer wall of the air outlet. By driving the fan blade 19 to rotate through the driving motor 17, a strong air flow is generated, which quickly brings out the heat inside the power amplifier box body 1 and discharges it into the external environment through the air outlet. This active heat dissipation method is more efficient than natural heat dissipation and can significantly reduce the working temperature of the power amplifier unit.

[0028] A signal connector 6 is installed on the surface of the power amplifier box body 1. A radio frequency connector 7 is installed on one side of the signal connector 6. A plurality of control buttons 8 are installed on one side of the radio frequency connector 7. The control buttons 8 are electrically connected to the signal connector 6, the radio frequency connector 7, the transformer 15 and the drive motor 17. The plurality of control buttons 8 allow users to directly operate the power amplifier, such as adjusting the volume, switching the signal source, controlling the sound effect, etc., improving the convenience and flexibility of use, and enabling users to quickly adjust the working state of the power amplifier according to needs.

[0029] On one side inside the power amplifier box body 1, a main board 12 is installed. On one side of the surface of the main board 12, a power supply filter capacitor 13 is installed. On the other side of the surface of the main board 12, a plurality of heat dissipation fins 14 are installed. On the other side inside the power amplifier box body 1, a transformer 15 is installed. The power supply filter capacitor 13 can filter out high-frequency noise and ripples in the power supply, providing a clean and stable DC power supply for the power amplifier, thereby improving the sound quality and reducing noise. The heat dissipation fins 14 improve the heat dissipation efficiency and reduce the internal temperature of the power amplifier by increasing the heat dissipation area and the contact area with the air.

[0030] At the four corners of the bottom end of the power amplifier box body 1, a base 16 is fixedly installed. At both ends of the side wall of the power amplifier box body 1, mounting plates 3 are fixedly installed. Mounting holes 301 are provided on the surface of the mounting plates 3. The design of the base 16 provides stable support for the power amplifier box body 1, reducing shaking and displacement caused by uneven ground or vibration, thereby ensuring the stability of the power amplifier during operation. The design of the mounting plates 3 and the mounting holes 301 on their surfaces makes the installation of the power amplifier box body 1 simple and fast. Users only need to connect the mounting plates 3 to the wall, bracket or other fixtures through fasteners such as bolts and screws to complete the installation of the power amplifier.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
