Abstract

Solar, wind, and fuel cell are some example of power source that are environmentally friendly. Hence, portable power supply product that uses solar energy as energy source was introduced. This product can supply electric energy to home furniture such as fan, lamp and drill. As the portable power supply product continue to grow, thermal issues are becoming extremely important for the product reliability. Portable power supply is a hand–held electronic equipment that is placed in a completely sealed enclosures due to safety factors. Since the cooling system of this product relies primarily on natural convection, the effective thermal management was quite low. Any electronic component will produce heat while operate and each electronic component have their own maximum temperature allowed during the operation. For this project, battery, adapter and inverter of the portable become the main heat source. Therefore, CFD model was develop by using ANSYS FLUENT software to study heat flow inside portable power supply. CFD model results were analysis and study to optimize thermal removal system of the portable power supply. Plus, experiments also will conduct for this project in order to study heat flow inside Portable power supply thoroughly. CFD model analysis show that by placed main heat source such as battery at the middle position compare to rear position will have better heat removal system. Besides that, by hollowed, added fan blower to the portable power supply, the temperatures inside the portable power supply will decrease and the efficiency of heat removal system will increase.
