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