Abstract

Genellikle soğutucular, PCB/ICs ve elektronik
cihazların sıcaklığını belirli bir aralıkta tutmak için yaygın olarak
kullanılırlar. Soğutuculardan, hem termal olarak maksimum soğutma hem de
çevresindeki komponentlere minimum elektromanyetik girişim (EMI) sağlaması
beklenir. Özellikle yüksek frekanslarda çalışan cihazlarda, soğutucuların
elektriksel boyutları çalışma frekansının dalga boyuyla karşılaştırılabilir ise
bu yapılar anten gibi davranır. Bu çalışmada, elektronik devrelerde kullanılan
silindirik yapıdaki soğutucuların EMI davranışları 0-10 GHz bandı için
incelenmiştir. Ölçümler tam yansımasız odada gerçekleştirilirken, benzetimler CST
MW-Studio benzetim programıyla yapılmış ve elde edilen sonuçlar
karşılaştırılmıştır. Benzetim ve ölçüm sonuçlarının birbiri ile uyumlu olduğu
görülmüştür. Soğutucunun yansıma katsayısı, ışıma örüntüsü ve E-alan dağılımı
elde edilmiştir. Ayrıca tasarım parametrelere bağlı olarak E-alan değişimleri
verilmiştir. Önerilen soğutucunun rezonans frekansı 3,75 GHz olarak elde
edilmiş olup ve soğutucunun taban geometrisine bağlıdır. Ayrıca, E-alan dağılım
genliğinin frekans artışı ile azaldığı tespit edilmiştir.
