HEAT TRANSFER PERFORMANCE IN 3D INDUCED FINNED HEAT PIPE

ABSTRACT
3D induced finned steel-water heat pipe is carried out in this project.

All the main parameters that can significantly influence the heat transfer performance of heat pipe ,such as working temperature, heat flux, inclination angle, working fluid fill ratio (defined by the evaporation volume), have been examined.


The evaporation and condensation heat transfer coefficients in 3D induced finned
heat pipe are found to be increased, as compared to the smooth gravity-assisted heat pipe under the same conditions.

Therefore, it is concluded that the special structures of 3D-fins on the inner wall can significantly reduce the internal thermal resistance of heat pipe and then greatly enhance its heat transfer performance.
