Investigation of MOF-303 – Active Carbon Mixtures for Passive Thermal Management Applications

Abstract

Small sized electronics and IoT devices can be thermally managed through sorbent heat sinks if economical and efficient solutions are developed. Here, we investigate a mixture of metal-organic frameworks and active carbon to lower the costs and increase the water uptake capacity. The mismatch on particle size and physical properties between the two sorbents lead to favorable desorption characteristics while also cutting down on costs. We spray coat the mixture onto copper substrates to obtain passive sorbent heat sinks. Our results display an ≈30% enhancement in the water uptake capacity and an ≈10% improvement in the thermal performance for the heat sinks coated with the mixture when compared to the only MOF case. The enhancement is attributed to fast desorption in the early phases of operation and to slow desorption in the steady state. Furthermore, we also study the coating microscopically through infrared imaging and observe that the carbon is colder than the MOF particles due to the lower thermal conductivity it possesses. This study not only demonstrates an economic way of enhancing the cooling performance of sorbent heat sinks but it also serves as a guideline for the design of desorption driven thermal management strategies.

MOF-303 – Aktif Karbon Karışımlarının Pasif Isı Yönetimi Uygulamaları için İncelenmesi

Abstract

Küçük boyutlu elektronik ve nesnelerin interneti cihazlarının ısıl yönetimleri ekonomik ve yüksek verimli çözümler geliştirilmesi halinde desorpsiyon temelli ısı emiciler aracılığıyla gerçekleştirilebilir. Bu çalışmada, bu tarz sistemlerin maliyetlerini düşürmek ve su alım kapasitelerini artırmak amacıyla metal-organik çerçeve - aktif karbon karışımları incelenmektedir. İki emici arasındaki parçacık boyutu ve fiziksel özelliklerdeki farklılıklar uygun desorpsiyon özelliklerine yol açarken, aynı zamanda maliyetleri de düşürmektedir. Isıl yönetim uygulamaları için pasif desorpsiyon temelli ısı emiciler elde etmek amacıyla üretilen MOF-karbon karışımı bakır yüzeylere püskürtülmüştür. Elde edilen ısı emiciler test edilmiş olup; sonuçlarımız, yalnızca MOF temelli kaplama durumuna kıyasla MOF-karbon bazlı ısı emicilerin su alım kapasitesinde ≈%30'luk bir iyileşme ve termal performansta ≈%10'luk bir iyileşme elde edildiğini göstermektedir. Bu iyileşme, operasyonun erken aşamalarında hızlı desorpsiyona, ve sabit hal durumunda yavaş desorpsiyona atfedilmektedir. Ayrıca, kaplamalar kızılötesi görüntüleme yoluyla mikroskobik olarak da incelenmiş ve karbonun sahip olduğu daha düşük termal iletkenlik nedeniyle MOF parçacıklarından daha soğuk olduğu gözlemlenmiştir. Bu çalışma sadece desorpsiyon temelli ısı emicilerin soğutma performanslarını arttırmanın ekonomik bir yolunu göstermekle kalmayarak, aynı zamanda desorpsiyon odaklı termal yönetim stratejilerinin tasarımı için bir kılavuz haline de gelmiştir.
