The importance of the vacuum is so that there is neither conduction nor convection.
In the conduction, the heat is transferred from the hot object to a cold object with the physical contact while in convection the heat is transferred from the object with the moving fluid then it will go somewhere else.
With vacuum, it will be impossible to transfer heat.
