“…It was concluded that the solar cells immersed in the nonpolar silicon oil had the best performance and had good stability for the encapsulation of solar cells. Hence, these studies [31][32][33] provide support for the method of cooling of photovoltaic systems by immersing them directly in the liquids.…”

“…Liu et al [31] proposed a novel cooling method for solar cells under concentrated solar flux where the surplus heat was removed from both the front and back surfaces of the module by directly immersing the cells in a dielectric liquid. In their study, a long-arc xenon lamp was used as an illumination source and dimethylsilicon oil was used as the dielectric fluid.…”

“…Pasif soğutma genellikle ısınan yüzeye kanatçıklar yerleştirilmesiyle gerçekleşmektedir. Aktif soğutma ise fotovoltaik hücrelerin ısınan yüzeylerinin akışkan vasıtasıyla soğutulmasına dayanmaktadır [2]. Yüksek yoğunluklu güneş ışınlarının etki ettiği sistemlerde aktif soğutmanın daha etkin olduğu görülmüştür [3].…”

ÖzGüneş enerjisinden elektrik enerjisi üreten sistemlerde fotovoltaik hücrelerin soğutulması sistem verimini artırmaktadır. Bu hücrelerin soğutulması için birçok yöntem ve parametre mevcuttur. Bu çalışmada alt yüzeyinde kanatçıklar bulunan fotovoltaik güneş panelinin dielektrik sıvıya daldırma yöntemi ile soğutulmasında soğutma kanalı geometrisi ve panel konumunun fotovoltaik hücre sıcaklıklarına etkisi sayısal olarak incelenmiştir. Sayısal analizler kanal çıkış genişliği, panelin eksenel ve radyal yöndeki konumu parametreleri için gerçekleştirilmiştir. Ayrıca, parametre değerlerinin değişimi ile oluşan ek basınç kayıpları hesaplanarak soğutma için gerekli enerji gereksinimi ortaya konulmuştur. Analizler sonucunda kanal çıkışının daraltılması ve panelin eksenel konumunun kanal çıkışına yakın olması durumunda fotovoltaik hücreler için daha etkin soğutma sağlandığı gözlemlenmiştir. Sayısal çalışma sırasında elde edilen bulgular sıcaklık, basınç değişimi, hız ve sıcaklık kontörlerini içeren grafikler halinde ayrıntılı olarak sunulmuştur.Anahtar Kelimeler: Fotovoltaik hücre, Güneş paneli, Sıvıya daldırma Effect of Channel Geometry and Panel Position at Cooling of Photovoltaic Solar Panels with Liquid Immersion Method AbstractToday, energy consumption have increased significantly because of developed technology. Therefore, using of fossil fuels have increased step by step. All of these have caused increasing of renewable energy sources and sustainable energy researches. In this study, the effect of cooling channel geometry and panel position on the temperature of photovoltaic cells are investigated at cooling of the photovoltaic solar panel that has fins on its bottom surface, with liquid immersion cooling method, numerically. Numerical analyses are carried out for parameters of channel outlet width, axial and radial position of the panel. Also, additional pressure losses that occurred with variation of parameter values are calculated and energy requirement is introduced for cooling. In consequence of analyses, it is observed that more effective cooling is provided in the case of narrowing of the channel outlet and panel position is close to channel outlet. Findings obtained during the numerical study are presented as graphics that include temperature, variation of pressure, and velocity contours in detail.

“…Furthermore, the direct contact liquid immersion cooling provides an opportunity for heat to be taken away from both the upper and lower solar cells surface, which increased the heat transfer area by contrast with former cooling approaches. Our former study focus on liquid direct immersion cooling lower and medium CPV systems [7][8][9][10][11][12][13], furthermore, the attempt of using water immersion solar cells under 250X in dish CPV system had been done [14][15]. However, the water has some disadvantages and the proper immersion liquid was silicon oil [13,16], meanwhile, the heat transfer performance of silicon Solar Cells Under High Concentration Ratio oil direct immersion cooling solar cells under high concentration ratio has not been reported in literatures.…”

Abstract:In order to solve the heat dissipation problem of densely-packed solar cells in high concentration photovoltaic (HCPV) system, a new cooling method of using silicon oil directly immerse the solar cells was proposed. The heat transfer performance of silicon oil immersion cooling the densely-packed solar cells with and without fin structure was investigated through experiment and simulation methods. The results of heat transfer performance of solar cells without fin structure showed that the simulated data was consistent well with data of experiment and the temperature could be lowered down in the operation range of solar cell. Furthermore, the heat transfer performance of solar cells with fin structure was researched using the model under different silicon oil inlet temperatures, inlet flow rates and the flow pressure drop was measured. The results indicated that the solar cells temperature declined and distributed well with silicon oil inlet flow rate increasing but the solar cells temperature raised linearly with silicon oil inlet temperature increasing. The optimized parameters of cooling receiver with fin structure were that: height of fin was 14 mm, number of fin was 50 and the thickness of substrate was 1.5 mm, with which the large amount of heat of densely-packed solar cells under high concentration ratio could be well controlled and make sure the power generation of HCPV system was high efficient.
