摘要
采用可调节温度和流量的热空气,流经截面50mm×50mm、壁厚2mm的紫铜方管,4片热电片沿纵向安装在方管外壁面,并采用循环水冷却的方式搭建了测试实验台。系统利用MCGS组态软件与亚当模块(ADAM)系列进行数据采集处理,可实时显示输出电压、电流及功率值。利用实验测试数据绘制塞贝克效应曲线、温差发电模块的输出特性曲线、P-R曲线、内阻与温差关系等。实验结果为建立热电片的电源模型和小温差的最大输出功率提供了实验检验基础。
The experimental system uses hot air with adjustable temperature and flow, and flows through a 50mm×50mm copper square tube with a wall thickness of 2mm. Four thermoelectric sheets were mounted on the outer wall of the square tube in the longitudinal direction, and a test bench was built by circulating water cooling. The data acquisition part used the MCGS configuration software and the Adam module (ADAM) series for data acquisition and processing, and the output voltage, current and power value could be displayed in real time. The experimental test data was used to draw the Seebeck effect curve, the output characteristic curve of the thermoelectric module, the P-R curve, the relationship between the internal resistance and the temperature difference, etc. The experimental results provided an experimental test basis for establishing the power model of the thermoelectric sheet and the maximum power output of the small temperature difference.
