Abstract

A grooved sintered wick for a heat pipe is provided having a plurality of individual particles which together yield an average particle diameter. The grooved sintered wick further includes at least two adjacent lands that are in fluid communication with one another through a particle layer disposed between the lands where the particle layer comprises at least one dimension that is no more than about six average particle diameters. A heat pipe is also provided comprising a grooved wick that includes a plurality of individual particles having an average diameter. The grooved wick includes at least two adjacent lands that are in fluid communication with one another through a particle layer disposed between the lands that comprises less than about six average particle diameters. A method for making a heat pipe wick in accordance with the foregoing structures is also provided.

Claims (10)
