This document summarizes research on the heat transfer performance of a 3D induced finned heat pipe. The researchers examined how parameters like working temperature, heat flux, inclination angle, and working fluid fill ratio influence heat transfer. They found that the evaporation and condensation heat transfer coefficients were higher for the 3D finned heat pipe compared to a smooth gravity-assisted heat pipe under the same conditions. The 3D fins on the inner wall reduced the internal thermal resistance and enhanced the heat pipe's transfer performance.

2. ABSTRACT
 3D induced finned steel-water heat pipe is carried
out in this project.
 All the main parameters that can significantly influe
nce the heat transfer performance of heat pipe ,su
ch as working temperature, heat flux, inclination an
gle, working fluid fill ratio (defined by the evaporati
on volume), have been examined.

3.  The evaporation and condensation heat transf
er coefficients in 3D induced finned
heat pipe are found to be increased, as compa
red to the smooth gravity-assisted heat pipe un
der the same conditions.
 Therefore, it is concluded that the special struc
tures of 3D-fins on the inner wall can significan
tly reduce the internal thermal resistance of he
at pipe and then greatly enhance its heat transf
er performance.
