SPECIFIC FOCUS ON CT AND THERMOSIPHON
Do the cooling coils we source live up to our specifications?
How do we ensure specified quality when soldering?

A thermosiphon is a passive cooling system consisting of:
1. An evaporator coil2. A condenser coil3. An airflow through the evaporator (via fan)4. An airflow through the condenser (via fan)5. Piping and soldering6. Gravity
What does a thermosiphon consist of?

To answer this, we used microscopy (and grind /cut)
Microscopy is a well-known and reliable method, but relatively expensive and time consuming

Our first scan was a section of a coil
After intro to the AM cluster of Teknologisk Institut in Denmark, we participated in the first meeting for CT scans
Our first assumptions were incorrect: the zipper fin angles were correct, but the scan showed an issue the header material. This was a corrective result, which we could not have achieved via the first method.
