According to the energy balance of the combustion engine, efficiency of internal combustion engine is around 30%, remaining energy is wasted as exhaust gas, which has a high percentage of loss 40%, and rest are wasted in lubrication, cooling water and radiation. In order to increase the efficiency of engine lot of researchers try to recover waste energy from the exhaust gas, among that thermoelectric generator (TEG), plays an important role in recovering waste energy from the exhaust gas. Thermoelectric generator efficiency depends on the shape of heat exchanger, the size of the fins and material of the thermoelectric element. In this paper, four different configurations of heat exchange modeled and compared through Computational Fluid Dynamics (CFD) software. They are Fishbone shape, accordion shape, and serial plate and empty cavity heat exchangers. The Serial plate has better heat transfer rate than Fishbone, accordion and empty cavity heat exchanger.
