Abstract
A method for manufacturing a heat pipe. Activated particles or particle clusters are formed. The activated particles or particle clusters are contacted with a working fluid in a non-oxidizing environment to form a chemisorbed layer of the working fluid thereon to generate chemisorbed working fluid surfaced activated hydrophilic particles or activated hydrophilic particle clusters which provide a solid-liquid contact angle to working fluid when subsequently added of <30 degrees. The chemisorbed working fluid surfaced activated hydrophilic particles or hydrophilic particle clusters are vacuum transferred and filled inside the heat pipe along with an additional volume of working fluid. The heat pipe is then sealed.
