PERFORMANCE ASSESSMENT OF COMMERCIAL HEAT PIPES WITH SINTERED AND GROOVED WICKS UNDER NATURAL CONVECTION

Öz:
Heat pipes are widely used in thermal management of high heat flux devices due to their ability of removinghigh heat loads with small temperature differences. While the thermal conductivity of standard metal coolers isapproximately 100–500 W/m.K, effective thermal conductivities of heat pipes, which utilize phase-change heattransfer, can reach up to 50,000 W/m.K. In industrial applications, commercially available heat pipes are commonlypreferred by thermal engineers due to their low cost and versatility. Thermal performance of a heat pipe is functions ofheat pipe type and operating conditions. Selection of the appropriate heat pipe complying with the operating conditionsis critical in obtaining satisfactory thermal management. One key point for the utilization of heat pipes is to avoid dryoutoperation condition in which heat pipes operate no more at the desired heat transport capacity. In the current study, theperformance of cylindrical heat pipes with sintered and grooved wick structures, which are among the most commonlyused types, is experimentally tested at different heat loads, gravitational orientations and ambient temperatures. Dryoutlimits of the heat pipes are determined and the relationship between the dryout onset and operating conditions iselucidated. The results reported in the present study are expected to guide thermal engineers for the proper selectionand operation of conventional heat pipes.

SİNTERLİ VE OLUKLU FİTİL YAPILARINA SAHİP TİCARİ ISI BORULARININ DOĞAL TAŞINIM ALTINDA PERFORMANSLARININ SINANMASI

Öz:
Isı boruları, yüksek ısı akılarını küçük sıcaklık farkları ile uzaklaştırabilme yeteneklerinden dolayı, yüksek ısı akısına sahip cihazların termal yönetiminde yaygın olarak kullanılmaktadır. Standart metal soğutucuların ısıl iletkenliği yaklaşık 100–500 W/m.K iken, ısı transferi için faz dönüşümü prensibinden faydalanan ısı borularının ısı iletkenleri 50,000 W/m.K 'e kadar ulaşabilmektedir. Uygun maliyetleri ve çok yönlü kullanımları sebebiyle ticari olarak mevcut olan ısı boruları termal tasarım yapan mühendisler tarafından endüstriyel uygulamalarda sıklıkla kullanılmaktadır. Isı borularının termal performansı tipine ve operasyon koşullarına göre değişmektedir. Sağlıklı bir termal yönetim için operasyon koşullarına uygun olacak şekilde uygun ısı borusu tipinin seçilmesi önemlidir. Isı borusu kullanımında en önemli nokta ısı borusunun kurumasının engellenmesidir, çünkü ısı borusunda kurumanın başlaması ile ısı borusu artık istenilen ısı taşıma kapasitesine ulaşamamaktadır. Bu çalışmada, en yaygın kullanılan tipler olan sinterlenmiş ve oluklu fitil yapısına sahip silindirik ısı borularının performansı, farklı ısı yüklerinde, yer çekimi konfigürasyonlarında ve ortam sıcaklıklarında deneysel olarak test edilmiştir. Bu çalışmada ısı borularının kuruma limitleri belirlenmiş ve kuruma başlangıcı ile çalışma koşulları arasındaki ilişki açıklığa kavuşturulmaya çalışılmıştır. Çalışmada elde edilen sonuçların ısıl tasarım mühendisleri için doğru ısı borusu seçiminde ve ısı borusunun doğru kullanımında bir kılavuz niteliği taşıyacağı düşünülmektedir.
