| 针对大功率光学器件和设备的热严重影响其稳定性、性能和使用寿命的问题，提出了一种基于能量回馈的智能高效热电散热系统。利用基于改进的增量式比例积分微分（PID）算法快速实现高精度温度控制，通过能量回收机制实现热电制冷器（TEC）制冷效率的提升。采用光伏充电为主、电源充电为辅的电源管理策略，通过上位机监测与控制实现对两组蓄电池的高效充放电切换。同时，利用Python+PyQt5为散热系统搭建可视化图形操作界面。研究表明，设计的实验系统实现了对TEC器件的电路信息监测与温度高效控制，可为解决大功率光学器件和系统的散热问题提供参考。 |

| Aiming at the problem that the heat of high-power optical devices and equipment seriously affects their stability, performance and service life, an intelligent and efficient thermoelectric cooling system based on energy feedback is proposed. Based on high precision temperature control realized by the improved incremental proportional integral differential (PID) algorithm, energy recovery mechanism isused to promote the efficiency of the thermoelectric cooler (TEC) refrigeration. Photovoltaic (PV) power management strategy is used through PC monitoring and control of the two groups of efficient storage battery charging and discharging switch. At the same time, Python+PyQt5 is used to build a visual operation graphical interface. The results show that an experimental system for circuit information monitoring and temperature efficient control of TEC device is designed and realized. This study is expected to provide a feasible cooling scheme for high-power optical devices and systems. |
