Produce electricity from exhaust gases in the vehicles used thermoelectric generator

In this study, A prototype has been developed as the working principle of thermoelectric generators. The exhaust system of a diesel engine used for the surface will be heated and as a result of operation of the engine profit by heat energy of the exhaust gases. Required cooling effect in the occur of the different temperature of TEM's is realised by an cooling system without engine. Reguired electric power of this system is 20 W. Electrically are connected as series with each other thermoelectric modules realised assembly octagonal structure consisted from the aluminum 6160 material. The battery charging is performed with electrical power supplied to DC / DC converter. Then in the system, heat-flow analysis was realised with the help Fluent which contained in the Ansys Workbench 12.0 and in the same time meaning Computational Fluid Dynamics (CFD) software. Finally, TEM's was heat-electric analysis carried out with the help Thermal-Electric which contained in the Ansys Workbench 12.0 and in the same time meaning Finite Element Method (FEM) software. The maximum electrical output power produce of the TEJ system is registered as 156.7 W at the 3500 rpm and 100 Nm as of the engine working condition.
