Description

Technical Field

[0001] This utility model relates to the field of power amplifier technology, specifically to a microwave power amplifier with good heat dissipation. Background Technology

[0002] A power amplifier is an amplifier that can produce maximum power output to drive a load under a given distortion rate. The power amplifier plays a pivotal role in the entire audio system, and to some extent determines whether the entire system can provide good sound quality output.

[0003] For example, the Chinese authorized patent, CN218735698U, entitled "(A Microwave Power Amplifier)," includes: a housing with two mounting ports, each with a dustproof mesh installed on its inner surface, and each dustproof mesh having an avoidance opening; the housing's interior is equipped with cooperating heat dissipation and airflow guiding components; and the housing also has a dust removal component. This invention replaces the traditional heat dissipation structure of microwave power amplifiers, expanding the heat dissipation area of ​​the cooling fan, ensuring the heat dissipation performance of the microwave power amplifier, and preventing dust from clogging the two dustproof meshes, allowing airflow to pass smoothly through the meshes and thus ensuring the heat dissipation performance of the microwave power amplifier.

[0004] However, existing microwave power amplifiers, once their locations are fixed and not moved, accumulate dust, which directly affects the heat dissipation performance of the device. Therefore, they do not meet current requirements. To address this, we propose a microwave power amplifier with better heat dissipation. Utility Model Content

[0005] The purpose of this invention is to provide a microwave power amplifier with good heat dissipation, so as to solve the problem mentioned in the background art that when existing microwave power amplifiers are used, dust accumulates because the setting position is fixed and will not be moved, which directly affects the heat dissipation performance of the device body.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a microwave power amplifier with good heat dissipation, comprising: a microwave power amplifier body, wherein a mounting cover is provided below the microwave power amplifier body, and a second reserved mounting hole is provided inside the outer wall of the mounting cover, and four second reserved mounting holes are provided;

[0007] Also includes:

[0008] A movable plate is installed above the main body of the microwave power amplifier. The main body of the microwave power amplifier has two reserved sliding grooves inside both ends. Both reserved sliding grooves are integrally formed with the main body of the microwave power amplifier. The lower end face of the movable plate is provided with a cleaning brush head. Several cleaning brush heads are provided. One end of several cleaning brush heads is fixedly connected to the movable plate. The upper end face of the movable plate is provided with a protrusion block, which is integrally formed with the movable plate.

[0009] Preferably, the upper surface of the microwave power amplifier body is provided with heat dissipation fins, and there are several heat dissipation fins, all of which are integrally formed with the microwave power amplifier body, and the several cleaning brush heads are located in the grooves between the several heat dissipation fins.

[0010] Preferably, each of the two reserved sliding grooves is provided with a pulley, and there are two pulleys. Each of the two pulleys is provided with a connecting block on the outside of both sides. The connecting blocks are rotatably connected to the pulleys through a central rotating shaft. One side of each connecting block is fixedly connected to both ends of the moving plate through a telescopic ring.

[0011] Preferably, the mounting cover is threadedly connected to the microwave power amplifier body by bolts, and the bolts are installed inside the second reserved mounting hole.

[0012] Preferably, mounting blocks are provided on both sides of the outer wall of the mounting cover, and four mounting blocks are provided. All four mounting blocks are welded to the mounting cover, and each of the four mounting blocks has a first reserved mounting hole inside.

[0013] Preferably, one end of the microwave power amplifier body is provided with an input terminal, and the other end of the microwave power amplifier body is provided with an output terminal.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This utility model, through the installation of a movable plate, cleaning brush head, reserved sliding groove, and pulley on the main body of the microwave power amplifier, allows the movable plate 200 above the main body 100 to be moved left and right after a period of use. During the left and right movement of the movable plate 200, the cleaning brush head 202 located on the lower end face of the movable plate 200 can clean the area of ​​the heat dissipation fins 103 on the main body 100 of the microwave power amplifier, removing dust and impurities accumulated on the grooves or outer walls of the heat dissipation fins 103, allowing the heat dissipation fins 103 to operate efficiently. This effectively avoids the problem of dust accumulation in existing microwave power amplifiers, where the fixed position does not allow for movement, thus directly affecting the heat dissipation performance of the device.

[0016] 2. By using telescopic rings and connecting blocks inside both ends of the moving plate, when the moving plate needs to be disassembled, the telescopic rings will retract the pulleys by squeezing, so that they can be easily removed from the cavity with the reserved sliding groove.
