İçten yanmalı motorların egzoz sistemleri için sıvı soğutmalı bir termoelektrik jeneratör sistemi tasarımı ve soğutucu akışkan miktarının geri kazanım performansına etkisinin deneysel incelemesi

Öz

Termoelektrik jeneratörler (TEJ) içten yanmalı motorların egzoz sistemlerinde atık enerjinin geri kazanımı için önemli bir alternatiftir. Bu çalışmada içten yanmalı motorların egzoz sistemlerinde atık ısının geri kazanımı için kullanılacak sıvı soğutmalı bir termoelektrik jeneratör sistemi tasarlanmış ve soğutucu akışkan miktarının geri kazanım sistemine etkisi deneysel olarak incelenmiştir. Soğutucu akışkan miktarının artması modül yüzeyleri arası sıcaklık farkını arttırmıştır. 4 adet TEJ modül kullanan geri kazanım sisteminde T_H=350 °C’ de 0.75, 1, 1.25 l/dk. akış miktarlarında sırasıyla 9.38, 10.05, 10.63 V yüksüz gerilim ve 1.7, 1.97, 2.16 W güç elde edilmiştir.

A design of a liquid cooling thermoelectric generator system for the exhaust systems of internal combustion engines and experimental study on the effect of refrigerant fluid quantity on recovery performance

Abstract

Thermoelectric generators (TEG) are an important alternative to the recovery of waste heat in the exhaust system of an internal combustion engine. In this study, a liquid-cooled thermoelectric generator system for waste heat recovery in exhaust systems of internal combustion engines was designed and the effect of the amount of refrigerant on the recovery system was experimentally investigated. The increase in the amount of refrigerant increases the temperature difference between the module surfaces In the recovery system using four TEG modules, at T_H=350 °C and flow rates of 0.75, 1, 1.25 l/min flow rate 9.38, 10.05, 10.63 V unloaded voltage and 1.7, 1.97, 2.16 W power were obtained respectively.
