Convection heat sink calculator
Webconvection is a condition with no external induced flow and heat transfer depends on the air surrounding the heatsink. The effect of radiation heat transfer is very important in natural convection, as it can be responsible for approximately 25% of the total heat dissipation. Unless the component is facing a hotter WebDec 8, 2024 · $\lambda$ = is the heat conductivity of the material in this case aluminimum ($\frac{kCal}{m°C}$) A is the total exchange surface $\Delta T$ the temperature difference; 2.2 Convective heat transfer. Convective heat transfer is when a solid surface and a fluid (liquid or gas) exchange heat. The total rate of exchanged heat is: $$\dot{Q} = h_c A ...
