Wicking structure plays a significant role in heat pipe. Heat pipe contacts the surface of heat source, the working fluid turns into vapor in the fully sealed vacuum pipe, then vapor flows along cavity to the cold interface and condenses back into the liquid and is absorbed by the wick (capillary action) to release the heat. The liquid then returns to the heat source and repeats the cycle.
Sinter powder, groove, and composite (groove + sinter powder) are the most adopted structures nowadays. Performance-wise, composite is superior to sinter powder then follows by groove.
