Özet:

 From past to present, humanity has used thermal conductive heat transfer method in all their daily needs, ranging from freezing food to heating during winter. The most important parameter of the heat transfer by conduction is determination of the thermal conductivity coefficient of materials. In this study, a low-budget thermal conductivity coefficient measurement device that can measure the thermal conductivity coefficient of bulk materials by means of Fouriers Law under steady-state conditions using absolute technical method in laboratory environment has been improved and fabricated. With a one-dimensional heat flow mechanism, heat conduction coefficient values of copper, brass and aluminum materials were determined experimentally, and calculated values were compared with existing values in the literature. The uncertainty analysis in measurement values of the fabricated device was calculated as 2.87. According to the experimental results, it was determined that values calculated from fabricated device are in good agreement with literature values copper and brass samples are in full compliance, but there is a 12 difference in aluminum sample. On the other hand, while accuracy professional thermal conductivity coefficient measurement devices used in laboratories is generally around 5, accuracy of the developed low-budget device has been determined to be between 0.1-12. It can be stated here that performance of the device developed is acceptable level compared to professional devices with high budgets. Also, in this study, preliminary research results of the low-budget device are shared, and additional improvements that need to be made in the fabricated device to increase the performance and to improve its shortcomings are also presented.

 Geçmişten günümüze insanlar, gıdalarını dondurmaktan kışın ısınmaya kadar her türlü günlük ihtiyaçlarında iletimle olan ısı transferi yöntemini kullanmışlardır. İletimle olan ısı transferinin en önemli parametresi, malzemelerin ısı iletim katsayısının belirlenmesidir. Bu çalışmada, yığın malzemelerin ısı iletim katsayısını kararlı rejim koşulları altında Fourier yasası yardımıyla laboratuvar ortamında mutlak teknik yöntemiyle ölçebilen düşük bütçeli bir ısı iletim katsayısı ölçüm cihazı geliştirilmiştir ve üretilmiştir. Bu kapsamda, geliştirilen tek boyutlu bir ısı akışı düzeneği ile; bakır, pirinç ve alüminyum malzemelerinin ısı iletim katsayısı değerleri deneysel olarak belirlenmiştir ve hesaplanan değerler, literatürdeki mevcut değerlerle karşılaştırılmıştır. Üretilen cihazın ölçüm değerlerindeki belirsizlik analizi 2,87 olarak hesaplanmıştır. Elde edilen deneysel sonuçlara göre, üretilen cihazdan hesaplanan değerler ile literatür değerler arasında genel olarak uyum içinde olduğu bakır ve pirinç numune de tam olarak uyum sağlanmış olup, alüminyum numunede 12lik bir fark söz konusudur tespit edilmiştir. Bununla birlikte laboratuvarlarda kullanılan profesyonel ısı iletim katsayısı ölçüm cihazlarının doğruluğu genellikle 5 civarında iken, geliştirilen düşük bütçeli cihazın doğruluğu 0,1-12 arasında olduğu belirlenmiştir. Buradan geliştirilen cihazın performansı, yüksek bütçeye sahip profesyonel cihazlara göre kabul edilebilir seviyede olduğu ifade edilebilmektedir. Ayrıca bu çalışmada, geliştirilmek istenen düşük bütçeli cihazın ön araştırma sonuçları paylaşılmış olup, tasarlanan cihazın performansının artırılması ve eksik yönlerinin geliştirilmesi için tasarlanan cihazda yapılması gereken ilave iyileştirmeler maddeler halinde de sunulmuştur.
