ANALYSIS AND FABRICATION OF HEAT PIPE AND THERMOSYPHON

Effective thermal conductivity of a heat pipe wick structure filled with a working fluid is measured. A simple evaluation method using a heating rod is described and the value of effective thermal conductivity is obtained by comparing the numerical results with the experimental ones. Full numerical simulation of heat pipes was performed for heat pipe under various operating conditions with water as working fluid. Two and three-dimensional models were developed assuming a laminar incompressible vapor core. Finally, a homogenous multiphase model referred to as volume of fluid modeling (VOF) was developed for simulation of a Heat pipe. A simple thermosyphon was fabricated. The thermal response time of a thermosyphon in comparison to a copper rod was observed. The response time and temperature profile along thermosyphon was measured. The effective thermal conductivity of it was calculated in a procedure like the heat pipe. Then the thermal conductivities of heat pipe and thermosyphon were compared. Using PRO-E/CATIA software we try to evaluate the design of the respective heat pipe. Later, we try to analyze the 3-D incompressible flow. The methodology of the project is to design the heat pipe system to carry out an analysis of the same using mechanical software based on the design and analysis of the heat pipe will be modeled.
