Dantherm specialty: Energy-efficient climate control solutions for shelters and cabinets
In both types of telecom sites thermosiphons are relevant as method of thermal management in the site. This presentations focuses specifically on CT Scanning in relation to the thermosiphon

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

The coil consists of:1. 2 headers2. MPE-pipes3. Zipper fins between
the MPE-pipes4. Louver fins, stamped out

Do the cooling coils we source live up to our specifications?

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.
