Heat pipes transfer heat at a minimum temperature difference between evaporating and condensing phase. Operating temperature of heat pipe is determined by working fluid and vacuum achieved during production. This paper is focused on determining the effect of initial temperature of ambient air to the performance characteristics of produced heat pipes. In general, a decrease in pressure decreases the boiling liquid. Based on this it can be presumed that achieving a lower temperature during production of heat pipe, the lower vacuum, while the boiling point working fluid while increasing ability to heat transport.
