一种用于电子设备的TEG系统设计与优化

摘要
传统路面集热发电方法只考虑了温度因素,为了优化传统路面集热系统对不同功耗电子仪器的适应性要求,采用车辙试验研究集热系统在车辙仪压力下的输出效率,并结合有限元分析研究沥青路面内部的温度场分布。实验结果表明,与传统路面集热系统方法相比,在70℃～80℃车辙仪作用下车辙试件的输出效率是静态下的2.8倍,且单位面积下车辙试件在4.5 h内收集的总能量为45.46 kJ,为传统实验方法的6～7倍。可见,路面集热实验需要考虑不同交通流量与环境温度的路面,所输出能量可满足不同功耗需求的电子测量设备,可用于电子设备数据采集等领域。
The traditional pavement surface collector power generation methods only consider the temperature factor. In order to optimize the adaptability requirements of traditional road surface heat collecting system for different power consumption electronic instruments, the rutting test is used to study the output efficiency of the heat collecting system under the pressure of the vehicle, and the temperature field distribution inside the asphalt pavement is studied by finite element analysis. The experimental results show that compared with the traditional pavement collecting system methods, the output efficiency of the rutting specimen under the action of 70～80 ℃ is 2.8 times that of static, and the total amount of rutting specimens per unit area collected within 4.5 hours. The energy is 45.46 kJ, which is 6～7 times that of the traditional experimental method. It can be seen that the road surface heat collection experiment needs to consider the road surface with different traffic flow and ambient temperature, and the output energy can meet the electronic measurement equipment with different power consumption requirements.
