The final goal is to design a heat sink for an electronic device that has 9 powerful LEDs of 2 W each. Calculate total heat resistance. Draw all the necessary diagrams. Make all the necessary assumptions based on the literature and cite them in the report. Show an improved design with schematics and comparative calculations and the improved thermal efficiency. You are allowed to change materials shown in the figure with appropriate materials without increasing total weight of the heat sink. In addition, you are expected to change the design geometrically (hints: cylindrical, rectangular, etc.). You must show all of your works. Assume if any data missing. 50 mm Copper (50 μm) 1.6 mm 10 mm LED וח 1 mm 1.5 mm Solderpaste (150 μm) Prepreg composite (glass-epoxy) (150 μm) Aluminum 6 mm LEDs 6 mm 50 mm 6 mm 6 mm The final goal is to design a heat sink for an electronic device that has 9 powerful LEDs of 2 W each.
