摘　　要：Cooling system design for thermal management of electronic equipment,batteries and photovoltaic(PV)modules is important for increasing the efficiency,safety operation,and long life span the products.In the present study,two different cooling systems are proposed with nano-enhanced multiple impinging jets for a conductive panel.The present cooling systems can be used in electronic cooling and PV modules.Perforated porous object(PPO)and sinusoidal porous object(SPO)are used in the jet cooling system.2D numerical analysis usingfinite volume method is conducted considering different values of permeability of the objects(Darcy number(Da)between 10^(-6) and 10^(-1)).When PPO is used in the cooling system,num-ber of cylinders(between 1 and 6),and size of the cylinders(between 0.015 and 0.075)are considered.In the case of using SPO,amplitude(between 0.1 and 2)and wave number(be-tween 1 and 12)are varied.Alumina-water nanofluid with cylindrical shaped nanoparticles is used as the heat transferfluid.When permeability is changed for PPO,the average temper-ature increases by roughly 3.89℃ for a single cylinder and drops by roughly 0.57℃ for a six-cylinder cases.Increasing the size of the cylinder in the PPO case at highest permeability results in temperature drop of 5.3℃.When changing the number of cylinders,cooling rate varies by about 3.6%.Wave number of SPO is more influential on the cooling performance enhancement as compared to amplitude and permeability of the SPO.The average surface temperature drops by 12.4℃ when the wave number is increased to 12.As compared to reference case of jet impingement cooling without porous object,using PPO and SPO along with the nanofluid result in temperature drop of 12.3℃ and 14.4℃.
