Thermal pads and thermal compound are used to fill air gaps caused by imperfectly flat or smooth surfaces which should be in thermal contact; they would not be needed between perfectly flat and smooth surfaces.
36.
This often happens as pressure builds up over time, usually by the physical and / or chemical release of gas or fluids from rock pore spaces, or thermal contact which changes the equilibrium pressure.
37.
"' Thermal insulation "'is the reduction of heat transfer ( the transfer of thermal energy between objects of differing temperature ) between objects in thermal contact or in range of radiative influence.
38.
Sometimes the shield was also fitted with thermal contacts to transfer heat from the glass envelope to the shield and act as a heat sink, which was considered to improve tube life in higher power applications.
39.
Typically they might be about 100 mm in diameter and perhaps about 5 mm thick and they need to be fixed firmly to the roof or wall which is under test in order to ensure good thermal contact.
40.
In the Carnot cycle there is strict necessity that the working fluid be at the same temperatures as the heat reservoirs they are in contact with and that they are separated by adiabatic transformations which prevent thermal contact.
