Abstract

Additive manufacturing enables researchers to form unique and unconventional topologies satisfying design compactness, improved efficiency, and lower cost. Design freedom introduced by the additive manufacturing reveals the idea of implementing the topology optimization approach into thermal systems. In this study, changes in thermal performance of three types of topologies: gyroid, hexagon (honeycomb), and rectilinear are experimentally investigated. In addition, porosity level of each topology is varied in between 25%, 50% and 75% to improve the impact of the study. The experimental results indicate that gyroid structures are thermally more efficient (up to 15.6%) than the remaining topologies. Furthermore, thermal diffusivities of the rectilinear and gyroid topologies with 25% porosity level are measured as the extremes, and it is detected that these structures propagate heat 1.1 times greater than the hexagon structure.

Özet

Eklemeli üretim, araştırmacıların tasarım kompaktlığı, gelişmiş verimlilik ve düşük maliyeti sağlayan benzersiz ve sıra dışı topolojiler oluşturmasına imkân verir. Eklemeli üretimin getirdiği tasarım özgürlüğü, topoloji optimizasyon yaklaşımını ısıl sistemlere uygulama fikrini ortaya çıkarmaktadır. Bu çalışmada, üç farklı tip topoloji için ısıl performansındaki değişimi deneysel olarak araştırılmaktadır: gyroid, bal peteği ve doğrusal. Ek olarak, çalışmanın etkisini artırmak için her topolojinin gözeneklilik seviyesi %25, %50 ve %75 arasında değiştirilmektedir. Deneysel sonuçlar, jiroid yapıların diğer topolojilere kıyasla ısıl yönden daha verimli (%15.6’ya kadar)olduğunu göstermektedir. Ayrıca, %25 poroziteye sahip doğrusal ve jiroid topolojilerin termal yayınımları uç noktalar olarak ölçülmüştür ve bu yapıların altıgen yapıya göre 1.1 kat daha fazla ısı yaydığı tespit edilmiştir.
