let us continue.
So why I chose liquid? Just because it has maximum area of the contact with elements that will be emit heat. Of course if we talk only about small satellite, we don't need such complex system and radiation of extra heat will be the best way. But if we imagine more complex structure, I think such system may be good solution.
I thought on a spaceship with crews we need water or liquids as an additional protection layer. In my opinion, we can use highly functional solid surfaces to do the same job as liquids. You are though right. For small satellites we can ignore the liquid and we get immediately to the point.
Now about model that we can build. First, it's very sad that we don't have any opportunity to put pictures here, so I will try may best to explain main idea as is. We can start from 2 dimensional system like this: space | external shell | |--other shells--| |--- space inside satellite, electronics etc. ---| |--other shells--| | external shell | space
| | |-- --| |---- ----| |-- --| | |
It is indeed sad that we cannot attach files. I would prefer a bottom to top image as electronic chips\their space package\distance to the interior satellite wall\next layer...\exterior layer and finally space. One can add two modifications in this system. One is aimed for better conductance very close to electronics and the other for better dissipation.
We can set initial parameters of such system according to known data about heat produced by electronics (so we will know how much energy is produced per unit of time), after, knowing conductivity of the materials of satellite shell we can calculate flux of heat through one part of the shell to another one. And finally how much energy can be dissipate into open space knowing parameters of the external satellite shell.
I agree. then we can insert modifications and make conclusions.
At this step we can use software like "scilab", for example. It's free and has many interesting features. P.S. My explanation is "raw", but I think you will understand main concept.
I had never heard of this software before. I will install it and try to discover it. I got the idea. It is my pleasure to discuss it with you. I wish you a wonderful year ahead in 2017.Any other comment?
