Test measurements of the Copper module.

At room temperature using water as coolant.

1 Watt = heater simulating Silicon detectors
4 Watt = heater simulating Chips
5 Watt = both


The Copper module






Where the temperature probes
are on the module?

















Test equivalence Copper module - TPG module


 The two-module setup






Where the temperature probes
are on the modules?











Conclusions
At the external edges (diagonales), the two modules are quite equivalent. On the contrary, the probes placed next to the cooling pipe (tuyau) show a big difference of temperature. This is due to the different thermal conduction features of TPG and Copper (TPG is very anisotropic).
