| الوصف: | Heat recovery systems have been widely used in order to improve the efficiency of engines (e.g Internal Combustion (IC) engines, air conditioning systems and other mechanical devices). A heat recovery system works by extracting the waste heat of a mechanical device which subsquently converting heat to useful energy (e.g electrical energy). Currently, the efficiency of IC engine is relatively low ranges from 31 to 40%. It means around 60 to 69% of the energy is wasted mostly in the form of heat (dissipated through the cooling process and exhaust gas) and friction. This waste energy has the potential to be extracted into useful energy by the use of a heat recovery system. This study aims to investigate the effect of fin configuration on the performance of thermoelectric generator heat recovery system. Experimental study was carried out on the exhaust gas recovery system using thermoelectric generators and heat pipes. The heat pipes were used as a conductor of heat from the exhaust gas passage with a slope of 30 degrees. Thin aluminium plates were mounting in contact with the heat pipes serving as the heat spreader. The hot sides of thermoelectric generators were attached to the thin aluminium plates to absorb the exhaust gas heat transferred through the heat pipe. A cooling system consists of fins and fan was placed in contact with the cold side of thermoelectric generators to dissipate the heat to the atmosphere. In this study, four configurations of fins at the exhaust gas passage of the heat recovery device is examined including finless, circular fins, squere fins 90o, square fins 45o. Each configuration is tasted at five engines speeds namely 1500, 2000, 2500, 3000,and 3500 RPM. The results showed that the engine speed and fin configuration affect the performance of the thermoelectric generator. The best performance of recovery systems is generated by the 45 degree square fin configuration. In which, at an engine speed of 3500 RPM, the recovery system with 45 degree square fin generates 17.98 V of voltage, ... |
