    Abstract
    Thermoelectric Devices are solid state devices which directly convert thermal energy to electrical energy and vice versa. In their recent past, a lot of effort has been made to improve the performance and also the power generated by a thermoelectric device. This is done by attaching heat sinks on either side of the device. Optimizing heat sinks improves the overall efficiency of it but on the other hand the device also has to be optimized. TECs are mostly used for electronic cooling where the heated electronic devices serve as target that needs to be cooled while air acts as a heat sink with natural convection. In this project, maximizing the cooling power of a TEC has been studied and its effect with respect to variations in the TE geometry has been discussed and using a 3D model of the same has been Sketch Up whose setup used has been explained in details. At low leg length of the TEC’s, the cooling power can be improved but a lot of other parameters have to be taken into account to accurately model the system. The contact materials used to electrically connect the device and the resistance of the conductor plays a very important role while calculating the cooling power at low leg lengths and hence cannot be neglected. Results show that cooling power of the TEC can be dramatically improved at low leg lengths and with better heat sink material.
