A platform for research: civil engineering, architecture and urbanism
At present, internal combustion engines (ICE) are still the main power source for cars, and about 60% of the fuel energy is wasted through exhaust gas and cooling system of ICE. One of the methods for energy recovery of ICE is to use thermoelectric generator (TEG). To improve the energy recovery efficiency of TEG, the temperature distribution over the cooling system should be known. For this purpose, the temperature filed of a TEG is analyzed using ANSYS software. In this paper, some inner structures of TEG are designed and their temperature fields are simulated. Through comparing the simulation with experimental results, the design with inclined symmetrical baffles can generate the most uniform temperature distribution. Then, this design is used to further simulate the cooling capacity of the TEG. The results show that the impact of thermal radiation should be considered in the TEG simulation; otherwise large errors will be generated. It also can be seen that the cooling method using solid plate connecting with a solid column has limitation because most of the heat is concentrated in the solid plate, and it should be optimized in further research.
