Editor’s note: This question was asked in response to Electronics Cooling’s recent webinar by Carl Zwebin. To view the webinar, click here. Question: Where can I get more information on advanced composite thermal management materials? What are the costs of the various materials you covered? Answer: I can provide overview articles. I also teach short courses in-house … [Read more...]
Radiative Cooling of Electronics (and Other Things)
In your basic heat transfer class, you should have learned that there are three primary modes of heat transfer: conduction (heat transfer through solids or stationary fluids), convection (heat transfer by virtue of moving fluids), and radiation. As a general rule, in electronics cooling situations, radiation is the least important mode, and is often neglected in first-order … [Read more...]
Thermal Spreading and More Using Open-Source FEA Software
The purpose of the present article is to suggest that accurate solution of thermal spreading problems for multilayer, edge-truncated geometry is easily accomplished using free, open-source finite element software. This should be especially attractive to designers and analysts who are full-time independent consultants, temporary contractors, or regularly employed … [Read more...]
Not Needing to Adjust Hot-Wire Anemometer Reading for Elevated Temperatures. Why Not?
Editor’s note: This question was asked in response to Electronics Cooling’s recent webinar by Roger Stout. To view the webinar, click here. Question: I've never heard that about not needing to adjust hot-wire anemometer reading for elevated temperatures. Why not? Answer: I don't know, luck? I published one paper on the subject, but it was really incidental, since we didn't … [Read more...]
'Normalized Transient Thermal Response' Curves – Can You be More Clear?
Editor’s note: This question was asked in response to Electronics Cooling’s recent webinar by Roger Stout. To view the webinar, click here. Question: I didn't understand what you were getting at with those "normalized transient thermal response" curves? Can you be more clear? Answer: Yes, I worried about that. There really wasn't time to get into it to the depth it deserved. … [Read more...]
