WebMay 1, 2001 · The table also shows an interesting range in thermal conductivity from a thermal engineering point of view. For example, the difference between polyimide and HD-polyethylene is a factor of five, which corresponds to the difference between natural and forced convection from a heat transfer capability point of view. WebThermal Conductivity Integrals •Advantages: –Simple –Only end point temperatures are important. (assuming there are no intermediate heat sinks) The actual temperature distribution is not. –Thermal conductivity integrals have been calculated for many engineering materials –This is quite useful for heat leak calculations June 2024 24
