Özet:

 In this study, the effects of electrical voltage, coolant fluid flow rate and nozzle diameter on the heat transfer performance on the heat sink were investigated in electrospray cooling, which has a very limited study in the literature. The experiments were carried out at a distance of 20 mm between the heat sink and the nozzle and heat fluxes of 1.88-2.02-2.19-2.4-2.59-2.75-2.99-3.2 kWm2. The experiments were carried out at a distance of 20 mm between the heat sink and the nozzle and heat fluxes of 1.88-2.02-2.19-2.4-2.59-2.75-2.99-3.2 kWm2. Ethanol was used as the coolant fluid. Experiments were carried out at voltages of 3.4-4.4-5.4 kV, flow rates of 0.1-0.2-0.3 mlmin and nozzle diameters of 20-25-30 G. As a result, it was determined that the heat transfer over the heat sink increased with the decrease in the nozzle diameter, the increase in the coolant fluid flow rate and the electrical voltage. Different electrospray mode was observed for each variable parameter, and effective cooling was obtained in multi-jet mode.

 Bu çalışmada literatüründe hakkında oldukça sınırlı çalışma olan elektrosprey soğutmada, elektrik geriliminin, soğutucu akışkan debisinin ve nozul çapının ısı alıcı üzerindeki ısı transfer performansına etkileri araştırılmıştır. Deneyler 20 mm ısı alıcı-nozul arası mesafede ve 1,88-2,02-2,19-2,4-2,59-2,75-2,99-3,2 kWm2 ısı akılarında gerçekleştirilmiştir. Soğutucu akışkan olarak etanol kullanılmıştır. 3,4-4,4-5,4 kV gerilimlerde, 0,1-0,2-0,3 mldk akışkan debilerinde ve 20-25-30 G nozul çaplarında deneyler yapılmıştır. Sonuç olarak nozul çapının azalması, soğutucu akışkan debisinin ve elektrik geriliminin artmasıyla ısı alıcı üzerinden gerçekleşen ısı transferinin arttığı belirlenmiştir. Herbir değişken parametre için farklı elektrosprey modu gözlemlenmiş, multi jet modunda etkili soğutma elde edilmiştir.
