Opis:: Heat pipes, as passive elements show a high level of reliability when taking heat away and they can take away heat flows having a significantly higher density than systems with forced convection. A heat pipe is a hermetically closed duct, filled with working fluid. Transport of heat in heat pipes is procured by the change of state of the working fluid from liquid state to steam and vice versa and depends on the hydrodynamic and heat processes in the pipe. This study have been focused on observing the impact these processes have on the heat process, the transport of heat within the heat pipe with the help of thermovision. The experiment is oriented at scanning the changes in the surface temperatures of the basic structural types of capillary heat pipes in vertical position.

Opis:: Heat pipes are devices, which transfer heat at a minimum temperature difference between evaporating and condensing phase. Operating temperature of heat pipe is determined by the working fluid and vacuum achieved during its production. This paper is focused on the determining the effect of the initial temperature of the ambient air to the performance characteristics of produced heat pipes. In general, the 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, the boiling point of working fluid while increasing ability of heat transport in various positions.
