Description

Technical Field

[0001] This utility model relates to the field of power amplifier technology, specifically a power amplifier monitoring module. Background Technology

[0002] A power amplifier (or simply "amplifier") is a key component in an electronic system used to amplify signal power. By controlling the power supply, a power amplifier converts the energy of a DC power supply into an AC signal output, thereby amplifying the signal power. Its core component is a transistor or field-effect transistor, which uses its current control effect in the amplification region to amplify small signals to large signals. In the radio frequency field, high-frequency power amplifiers often adopt nonlinear operating states (such as Class C) to improve efficiency, but approximate methods such as piecewise linear methods are required for analysis.

[0003] According to the battery monitoring module published on the China Patent Network with publication number CN219016526U, it includes a battery monitor body and a connector. The back of the battery monitor body is symmetrically fixed with sliding bars, and it also includes a cooling fan. Mounting plates are slidably mounted on the two sliding bars, and the mounting plates have a degree of freedom of movement along the axial direction of the sliding bars. The cooling fan is mounted on the side of the mounting plate away from the battery monitor body. This battery monitoring module is equipped with a cooling fan, which can be used to provide localized cooling for the independent battery monitor body in real time, achieving effective cooling and preventing damage to the battery monitor body due to heat generated by the electronic components, thus affecting its use. It also includes sliding bars, mounting plates, rotating plates, rotating shafts, slide rails, threaded rods, and rubber sheets for quick replacement of the cooling fan, facilitating rapid replacement when the cooling fan is damaged or aged, thus improving efficiency. However, this monitoring module has poor anti-interference performance. Because the power amplifier generates strong electromagnetic radiation during operation, the electronic components in the monitoring module are easily affected by this electromagnetic interference, leading to deviations in the monitoring data and reduced monitoring accuracy.

[0004] Therefore, the monitoring module needs to be redesigned and modified to effectively prevent electromagnetic interference. Utility Model Content

[0028] refer to Figure 3 The heat dissipation component 3 includes a heat-conducting plate 301. The bottom of the heat-conducting plate 301 is fixedly connected to the inside of the monitoring module body 1. The top of the heat-conducting plate 301 extends through to the top of the shielding frame 203. A heat dissipation fin 302 is fixedly connected to the top of the heat-conducting plate 301. The bottom of the heat dissipation fin 302 is fixedly connected to the top of the shielding frame 203. A support block 303 is fixedly connected to the top of the support block 303. A support frame 304 is fixedly connected to the top of the support block 303. A cooling fan 305 is fixedly connected inside the support frame 304. The cooling fan 305 is located on top of the heat dissipation fin 302.

[0029] As a technical optimization of this utility model, by setting up the heat dissipation component 3, the monitoring module body 1 can be cooled, preventing the monitoring module body 1 from overheating due to the anti-interference component 2, thereby improving the safety of the monitoring module body 1.

[0030] refer to Figure 4 Electromagnetic shielding film 4 is fixedly connected to the top of the shielding base plate 202 and the inside of the shielding frame 203. The shielding frame 203 is made of conductive metal.

[0031] As a technical optimization of this utility model, by setting the electromagnetic shielding film 4, the electromagnetic shielding effect of the shielding frame 203 can be increased, thereby improving the safety of the main body 1 of the monitoring module.

[0032] refer to Figure 4 Mounting plate 1 5 is fixedly connected to both sides of the shielding base plate 202, and mounting plate 2 6 is fixedly connected to both sides of the shielding frame 203. Mounting plate 1 5 and mounting plate 2 6 are connected by bolts.

[0033] As a technical optimization of this utility model, by setting up mounting plate 5 and mounting plate 6, it is easier for users to install and disassemble the shielding frame 203, thus improving the ease of installation and disassembly of the shielding frame 203.

[0034] refer to Figure 3 A conductive rubber block 7 is fixedly connected to the top of the main body 1 of the monitoring module, and the top of the conductive rubber block 7 is fixedly connected to the top of the inner wall of the shielding frame 203.

[0035] As a technical optimization of this utility model, by setting the conductive rubber block 7, the shielding frame 203 can be supported, thereby improving the overall strength of the shielding frame 203.

[0038] The working principle and usage process of this utility model are as follows: When anti-interference protection measures are required for the main body 1 of the monitoring module, the shielding frame 203 can be placed over the surface of the main body 1 of the monitoring module. The shielding frame 203 is then securely installed by connecting the mounting plate 1 5 and the mounting plate 2 6 with bolts. At this time, the shielding frame 203 and the shielding base plate 202 work together to effectively shield the electromagnetic interference generated by the power amplifier, preventing interference from entering the internal circuitry of the main body 1 of the monitoring module. Furthermore, the addition of the electromagnetic shielding film 4 further enhances the electromagnetic shielding effectiveness of the shielding frame 203, thus achieving comprehensive anti-interference effects. When the main body of the monitoring module 1 faces heat dissipation requirements, the heat conduction plate 301 plays a role in heat conduction, transferring the heat generated by the main body of the monitoring module 1 away in a timely manner. At the same time, the cooling fan 305 runs at full speed, generating airflow. This airflow passes smoothly over the surface of the heat dissipation fins 302, enabling the heat dissipation fins 302 to efficiently dissipate heat from the heat conduction plate 301. Thus, the heat conduction plate 301 dissipates heat from the main body of the monitoring module 1. In addition, the design of the vent 205 also plays a crucial role. It can promote air circulation and provide additional heat dissipation support for the main body of the monitoring module 1. With such coordinated operation, an excellent heat dissipation effect can be achieved.

[0039] In summary, this power amplifier monitoring module utilizes anti-interference components to electromagnetically shield the monitoring module. Even though the power amplifier generates strong electromagnetic radiation during operation, it prevents the electronic components in the monitoring module from being affected by this electromagnetic interference, avoids deviations in monitoring data, improves monitoring accuracy, and solves the problem of electromagnetic interference.
