Fans:
Fans are used to circulate air across the heat sinks, enhancing the heat transfer rate. They are commonly employed in air-cooling systems.
–
Liquid Cooling Technology:
Liquid cooling technology involves using water or a specialized liquid coolant to absorb the heat generated by the components. This method is more effective than air-cooling and is widely used in high-performance systems.
The effective heat transfer rate per unit area (q”/A) can be calculated using the equation: q”/A = h(Ts – Ta), where h is the convective heat transfer coefficient, Ts is the surface temperature of the component, and Ta is the ambient temperature.
