Abstract: There has been awesome enthusiasm on investigating the capability of waste heat extraction utilizing Thermoelectric Generator (TEG) system on marine application because of extraordinary measure of gas volume, numerous potential areas with predictable high temperature and accessibility of unbounded cooling ocean water. To enhance the general yield execution of TEG framework regarding proficiency, legitimate framework level of designing and coordination have been viewed as vital other than improvement of thermoelectric materials with bigger ZT (figure of legitimacy) and ideal control methodology of electrical interface system. In this research, preparatory exploratory examination and numerical displaying enhancement on the cooling system for a thermoelectric module level gadget are discussed. The anticipated open-circuit voltages by thermoelectric reproduction for gadget with customary water cooling plate are in great concurrence with the deliberate test information for different hot gas temperatures. The model is then amended for further reproduction to upgrade the cooling plate configuration by analyzing point by point warm execution and electrical current-voltage attributes for the thermoelectric module gadget with shifting electrical load. These examinations show that a good cooling system is essential for high effectiveness TEG usage. This module level perception serves to see how TEG framework incorporates and demonstrate potential change for TEG control transformation system. With great exactness, the utilized apparatus is prepared to do quickly describing TEG system level execution in future work.
