In this article, cooling of a mono-crystallinephotovoltaic cell (PV) having 0,00128 m2 top surface area wasstudied using Computational Fluid Dynamics (CFD) method. The PV cell wasexposed to different solar radiation values in both no-cooling and coolingconditions. Mini-channel cooling was performed by means of 12 aluminumrectangular channels having 0,0018 m hydraulic diameter and 40 mm length. Waterflow rate in channels was calculated corresponding to the Reynolds numbersranging from 500 to 2300 and its effect on the cooling was examined. Resultsshow that the temperature of the top surface of PV panel increases up to 57 ˚Cunder no-cooling condition and our analysis revealed that it can be decreasedto 25 ˚C when the mini-channel cooling is in progress.
Bu makalede, üst yüzey alanı 0,00128 m2 olanbir mono kristalin fotovoltaik (photovoltaic - PV) hücresinin soğutulmasıHesaplamalı Akışkanlar Dinamiği (HAD) yöntemiyle araştırılmıştır. PV hücresihem soğutmasız hem de soğutmalı durumlarda farklı güneş ışınımı değerleri içinanaliz edilmiştir. Soğutma sisteminin, 0,0018 m hidrolik çapa sahip, 40 mmuzunluğunda 12 adet alüminyum dikdörtgen mini kanallardan oluştuğu ve soğutucuakışkan olarak su kullanıldığı dikkate alınmıştır. Suyun kütlesel debisi 500 ≤Re ≤ 2300 aralığında hesaplanmıştır ve debinin soğutma üzerindeki etkisiincelenmiştir. Çalışmanın sonuçlarına göre soğutmasız analizlerde 57 ˚C’yekadar ısınan PV hücresi yüzey sıcaklığı, mini-kanal soğutma yöntemikullanılarak 25 ˚C’ye kadar soğutulmuştur.
