Abstract

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.
