热电机组(TEG)在余热回收系统中具有重要意义。在这项研究中，开发了一种适用于热电发电系统的工作原理样机。柴油机排气系统利用废气的热量对表面进行加热。此外，还采用了热电制冷系统，以满足不同温度下所需的制冷效果。在实验中，内燃式柴油发动机在五个不同的发动机速度和每个速度级别的两个不同的发动机负荷下使用。安装在由铝6061材料制成的八角形结构上的40件温差电模块的电气连接是串联的。从改变转速和发动机负荷的角度考察了TEG系统的性能。TEG系统的性能已经通过改变发动机的速度和负荷进行了检验。在该系统中，利用Ansys Workcale12.0中的FLUENT程序，同时编制了计算流体动力学(CFD)程序，进行了温度和流动分析。
Thermoelectric generator (TEG) has drawn significant for the waste heat recovery systems. In this study, a prototype has been developed for the working principle suitable to the thermoelectric generator systems. The exhaust system of diesel engine is used and benefited from the exhaust gas heat to heat the surface. In addition, thermoelectric cooling system is used for the cooling effect that is required under different temperatures. In experiments, internal combustion diesel engines are used in five different engine speeds and two different engine loads for each speed level. Electric connection of the 40-piece thermoelectric modules mounted on the octagon structure made from Aluminium 6061 material is made in series. Performance of TEG systems has been examined in terms of changing speed and engine load. The performance of TEG systems has been examined in terms of changing speed and load in the engine. In the system, with the assistance of fluent programme in the Ansys Workbench 12.0 and at the same time having the Calculating Fluid Dynamic (CFD) programme, the temperature and flow analysis is performed.
