Design and Operation of a Heat Pipe
designoperationo00burg.pdf (2.562Mb)Abstract
An experimental stainless steel heat pipe using water as the working
fluid and 400 mesh stainless steel screen for a wick was designed and
tested to determine the effect of gravity and nucleate boiling on heat
pipe performance. The results of heat pipe operation at various angles
of inclination in a gravity field are presented and compared with the
existing theoretical predictions. The maximum heat flux obtained experimentally at angles of inclination
less than 90 degrees was less than the predicted value by a factor
of two or three. The maximum heat flux obtained for an angle of inclination
greater than 90 degrees was much higher than that predicted. In
addition, nucleate boiling noise was detected during operation at
angles of inclination greater than 90 degrees. The experimental results coupled with visual examination of the
pipe after operation indicate that the pipe was not performing satisfactorily.
Recommendations for a better design of an experimental heat
pipe are presented.
