Conventions of colors: Red =copper; pink=insulation foam; blue =PVC frame beije=pvc plates (except the chamber) ;dark grey = Aluminum )
Cut view of the assembly
The box is composed of 3 layers : 1 )Copper plates + tubes for cooling system 2 ) Foam for heating insulation 3 ) PVC +Kapton for Nitrogen sealing (avoid dew point)
