interface resistance การใช้

However, the thermal conductivity does not take into account the interface resistances.
Tubes on standby for long periods, with heater voltage applied, may develop high cathode interface resistance and display poor emission characteristics.
Therefore, if a TIM has a high thermal conductivity, it does not necessarily mean that the interface resistance will be low.
The presence of thermal interface resistance, corresponding to a discontinuous temperature across an interface was first proposed from studies of liquid helium in 1936.
As a result, the acoustic mismatch model typically represents an upper limit for thermal interface resistance, while the diffuse mismatch model represents the lower limit.
