Abstract
In this study, the experiment of the cooling down of microprocessors with the aid of various heat tubes in the personal computers (pc) have been analysed. In heat sink systems, the sinked heat is thrown away from the system by using winged surface cooling down, therefore since the productivity of the wings is low, large dimensioned surfaces are needed. There is a risk of electrical malfunctioning and noice problem in fan systems. In cases of heat tubes reinforcing the wing surfaces, homogenous heat dispersal and high productivity in wings are gained. The job of banishing the heat away from the surface of CPU is successfully and securely provided, the noice and mechanical malfunctioning problem is prevented. In the experiments, three different liquids (R22, R404a ve ethanol) were used for the heat tubes ( single tube, multi-canal tube, straight and bended tube). Three different type of tubes and the liquids were compared. The single tube and ethanol has come up with the best results.
Abstract
Bu çaly?mada ki?isel bilgisayarlarda (PC) bulunan mikroi?lemcilerin (CPU), çe?itli ysy borusu tipleri ile so?utulmasy deneysel olarak incelenmi?tir. Isy biriktirmeli (heat sink) sistemlerde, biriken ysynyn sistemden atylmasynda kanatly yüzeylerle so?utma yapyldy?yndan ve kanat verimlerinin dü?ük olmasy sebebiyle büyük hacimli yüzeyler gerekmektedir. Üfleyici (fan) sistemlerde elektriksel aryza ihtimali ve gürültü problemi mevcuttur. Kanat yüzeylerinin ysy borusu ile takviye edilmesi durumunda homojen sycaklyk da?ylymy ve yüksek kanat verimlerine ula?ylmaktadyr. CPU üzerinde meydana gelen ysynyn yüzeyden uzakla?tyrylmasy, etkili ve güvenli ?ekilde sa?lanmakta, gürültü ve mekanik aryza sorunu ortadan kalkmaktadyr. Yapylan deneylerde, ysy borulary için (tek borulu, çok kanally borulu düz ve e?imli) üç farkly çaly?ma syvysy (R22, R404a ve etanol) kullanylmy?tyr. Üç farkly ysy borusu tipinin ve çaly?ma syvylarynyn verimlilikleri kar?yla?tyrylmy?tyr. Isy borularyndan düz tip ysy borusu ve çaly?ma syvylaryndan etanol en verimli aky?kan oldu?u tespit edilmi?tir.
