Description

Technical Field

[0001] The utility model belongs to the technical field of signal transmitters, in particular to a power supply device for a platform signal transmitter. Background Art

[0002] The platform signal transmitter is a radio transmitting device composed of a high-frequency carrier frequency oscillator that can generate equal-amplitude oscillations and a low-frequency oscillator that generates a low-frequency modulation signal. The platform signal transmitter mainly includes three parts: high-frequency part, low-frequency part, and power supply part. The high-frequency part generally includes a master oscillator, a buffer amplifier, a frequency multiplier, an intermediate amplifier, a power amplifier driver stage, and a final power amplifier. The function of the master oscillator is to generate a carrier with a stable frequency. In order to improve the frequency stability, the master oscillator often uses a quartz crystal oscillator, and a buffer stage is added behind it to weaken the influence of the subsequent stage on the master oscillator. The low-frequency part includes a microphone, a low-frequency voltage amplifier stage, a low-frequency power amplifier stage, and a final low-frequency power amplifier stage. The low-frequency signal is gradually amplified to obtain the required power level at the final power amplifier in order to modulate the high-frequency final power amplifier. Therefore, the final low-frequency power amplifier stage is also called a modulator. Modulation is the process of loading the information to be transmitted onto a certain high-frequency oscillation (carrier frequency) signal. Therefore, the final high-frequency power amplifier stage becomes a modulated amplifier. The power supply is the core component of the platform signal transmitter. Especially when the equipment is working in an outdoor environment, the stability and durability of the power supply are key factors affecting the normal operation of the equipment. At present, the power supply module used for the platform signal transmitter is generally installed in an integrated structure. This integrated structure ensures that the overall structure of the equipment is compact and can protect the power module with the overall structure of the equipment, but it is easy to cause poor heat dissipation, especially when the internal space of the equipment is relatively cramped. This phenomenon is particularly obvious. Summary of the invention

[0003] The technical problem to be solved by the utility model is that when the power module is installed in an integrated structure, the heat inside the platform signal transmitter cannot be dissipated smoothly.

[0004] In order to achieve the above technical objectives, the utility model adopts the following technical solutions:
