pHaestus identified it, a heat pipe
why the curves are the way they are is pretty obvious upon reflection
- not so obvious is the 4 days of testing (at 12 hrs/day, eh) to obtain repeatable results, and my initial disinclination to believe what I was seeing
pHaestus' results and his quandary expressed in this thread are a typical 'obstruction' encountered in this type of thermal testing, the smallest oversight can consume huge amounts of effort to identify the discrepant element
- this is not a criticism, pHaestus will do this many times more until he follows a written setup procedure - and establishes his own means of 'zeroing' the test bench prior to the collection of data
-> if the first data point does not replicate something already known there is always the potential to be heading off on a wild goose chase
take the time to ck everything out first
look at the Digitec photos, see those colored dots on the thermistor connectors and the face plates ?
(that was part of a setup control system)
