Riassunto analitico
Heat management has always been fundamental in spacecraft design since the
dawn of space
ight. A mission can fail, even catastrophically, for a poor heat
management on a single piece of hardware. More so if it is a fundamental part
that fails, like an engine or a solar panel. In the last few years, the progressive
miniaturization of electronics and space missions more and more demanding have
accentuated the attention on the research of new solutions to properly address the
problem.
Right now, two-phase heat transfer devices are becoming the predominant solution
for heat management, in particular sintered wick Heat Pipes (HP) and Loop Heat
Pipes (LHP). This is due to their reliability, lightness and, most of all, their
capability to operate without the assistance of any acceleration field. The latter is
obtained thanks to a wick, which is also the most complex and expensive element
inside the system, enhancing capillarity. A Pulsating Heat Pipe (PHP) is a special
kind of heat pipe that does not rely on a wick for capillarity but on the pipe itself
and thus it results cheaper and more apt to a space environment.
The work contained in this thesis is focused on the design, realization and the
subsequent micro-gravity tests on a specific design of Pulsating Heat Pipe that
will be hosted in the Heat Transfer Host on the International Space Station in
2020. In particular, it deals with the design, realization and integration of a Rack
for testing, set in the 67th ESA Parabolic Flight Campaign in November 2017 and
on a first analysis of the outcomes.
