Material type, surface area, flatness of contact surfaces, configuration, fan requirements are some of the factors that determines the heat sink performances.
Due to its high thermal conductivity, low cost, low weight and ease in manufacturability, aluminum is the most preferred material compared to copper.
The material for the plate is defined as aluminum and air at 25oC is chosen as the fluid for the present study.
