Gravitation Heat Pipe and Influence of Working Conditions

This work deals with heat transfer over heat pipe. In the introduction is knowledge about heat pipes. In the experimental part is influence of working conditions to heat transfer calculations of heat pipes Currently the problem with the increasing number of electronic devices is a problem with the outlet Joule heating. One of more alternatives of outlet joules heating without the using of mechanical equipment is the use of the heat pipe. Heat pipes are easy device to manufacture and maintenance of low input investment cost. The advantage of using the heat pipe is use it in hermetic closed electronic device which is separated exchange of air between the device and the environment. This experiment deals with the influence of changes in the working tube diameter, working position and changing the working medium depending on performance parameters. The result of this paper is finding the optimal working conditions with ideal working substance for the greatest heat transfer for 1cm 2 sectional area tube. One of more alternatives using heat pipes is a heat transfer Joule heating without the using of mechanical equipment.
