Bu
çalışmada, termoelektrik jeneratörlerin çalışma prensiplerine uygun olarak
çalışan bir prototip geliştirilerek içten yanmalı dizel bir motorun egzoz
sistemine uygulanmıştır. Amaç, egzoz gazlarıyla atmosfere atılan ısı enerjisini
kullanılabilir bir elektrik enerjisine dönüştürmektir. Termoelektrik modüllerin
çalışma şartı olan fark sıcaklıklarını oluşturmak amacıyla sistemde iki farklı
akışkan kullanılmıştır. Bunlardan ilki, sıcak yüzey şartını oluşturmak için
kullanılan egzoz gazlarıdır. Diğer akışkan ise, termoelektrik modüllerde
ihtiyaç duyulan fark sıcaklığının oluşmasını sağlayan soğutma suyudur.
Malzemesi alüminyum alaşım olan sekizgen yapıya yerleştirilen 40 adet
termoelektrik modül kendi aralarında elektriksel olarak seri bağlanmıştır.
Motorda değişen devir ve yük durumuna göre termoelektrik jeneratör sisteminin
performansı incelenmiştir. Aynı zamanda, termoelektrik jeneratör sisteminin
ürettiği elektrik enerjisi konvertöre aktarılarak araç aküsü şarj edilmiştir.
