The invention discloses a thermal management method, device and equipment for a vehicle-mounted power amplifier host and a storage medium, and belongs to the technical field of vehicles. The method comprises the following steps: firstly, analyzing audio data to be played in real time, predicting the power demand and the heating condition of a power amplifier host, calculating the output power and the heating power of the audio to be played in combination with the operation mode of the power amplifier host, and then adjusting the heat dissipation power in advance according to the predicted values. The hysteresis of a traditional heat dissipation mode based on temperature change is eliminated. According to the scheme, heating is predicted and heat dissipation is adjusted in time, so that equipment faults and performance reduction caused by overheating are reduced, and stable operation of the vehicle-mounted power amplifier host under various audio loads is ensured.
本发明公开了一种车载功放主机热管理方法、装置、设备及存储介质,属于车辆技术领域。本方法首先通过实时分析即将播放的音频数据,预测功放主机的功率需求和发热情况,结合功放主机的运行模式,计算出即将播放音频的输出功率和发热功率,然后,根据这些预测值提前调整散热功率,以消除传统基于温度变化的散热模式的滞后性。该方案通过预测发热并及时调整散热,减少了因过热导致的设备故障和性能下降,确保了车载功放主机在各种音频负载下的稳定运行。
