Abstract: (5642 Views)
High power diode lasers are widely used in industrial applications such as solid-state laser pumping schemes. The augmentation of the temperatures is an important issue in the optimum performance of these devices. In the present work, a numerical analysis was carried out for studying the heat transfer performance of copper porous heatsink using water- Al2O3 nanofluid destined to the cooling of 40 W CW diode laser. Results show the heat transfer rate of porous heatsink with nanofluid is more than the common heatsink with water coolant. Also the laser bar temperature decreases 9% by using porous heatsink comparison common heatsink due to the improved heat transfer coefficient by the tortuous flow path in the foam structure and increasing the effective thermal conductivity of nanofluid.
