Electronic Component Cooling
(OP)
Hi all,
Here is the situation. I am looking at material selection for a component acting as a heat sink. I need to determine the effect of each materials thermal conductivity on my entire system. I understand that as convection transfer decreases, thermal conductivity becomes less important as the convective transfer is the more limiting portion of the thermal system. Correct?
Here is the order of component interaction:
electronic component base, metal block, thermal pad, heat sink, air @ 25C
I am only recognizing convective heat transfer for the heat sink portion of this assembly.
I thought there was a relatively easy way to represent this system. I want to insert the thermal conductivity values for the different materials and compare the difference in junction temperature of the electronic component.
Thanks a lot for your help.

If this problem is simple, please respond but include your answer as a tutorial. It will be helpful for some of us rookies. I recall setting up resistance diagrams and using that method for determining estimated temperatures, but that was a long time ago.
Where do I find the material selection exercises for heat sink design?
RE: Electronic Component Cooling
As for heatsinks, the material of choice for more than 40 years is aluminum.
