.... Because the IC w-MCHS has a surface area that is only 6.4% higher than the s-MCHS, heat transfer enhancement through the surface area is insignificant, meaning that heat transfer enhancement is predominantly achieved by interrupting the thermal boundary layer. The waviness and interconnectors contribute...
