Gravity in Heat Pipe Technology

Abstract

This work deal with heat pipes experiments depending on the gravity, because gravity is one of the phenomenon which affects the heat transport ability of the heat pipe. In heat pipe technology is gravity on the one side positive when ensure the circulation of the working fluid in gravity heat pipe (GHP) (thermosiphon) and on the other side negative when act opposite the capillary action in the wick heat pipe (WHP). The work describes principle, design and construction of gravity heat pipe (GHP) and wick heat pipe (WHP). Experimen- tal determination influences gravity on the heat transport ability of gravity heat pipes by changing working position. Experimental andmathematical determination influences grav- ity on the heat transport ability of wick heat pipes by changing working position
