Tony Kordyban in California

air – the ultimate heat sink

a course by tony kordyban

tony has condensed over 25 years of practical experience into a one-day course

a short course on the basics of the most basic method for cooling electronics. air cooling is the method you are using even when you think you aren’t using any method.

topics to be covered:

  • · five minutes of heat transfer theory
  • · what is air? how can it be the perfect insulator and ideal heat transfer fluid at the same time?
  • · starting in the middle: understanding your cooling requirements.
  • · selecting the right air cooling scheme:
o the sealed box
o natural convection
o forced convection (the secrets of fans)
o radiation – the other air cooling
o assisted cooling – heat exchangers and air conditioning
  • · how much will be enough? hand calculations for sizing your cooling system
  • · no doghouses! – integrating the cooling into the system
  • · computational fluid dynamics – when you need to estimate your cooling to 12 significant digits
  • · what happens at higher altitude? nobody seems to know for sure.
  • · testing and my favorite test lab mistakes
  • · the limits of air cooling – when to give up and call in the plumbers
learn from the guy who spent 25 years engineering cooling solutions in the power, telecom, and military electronics industries, and then had the temerity to write about it in hot air rises and heat sinks: everything you know about cooling electronics is wrong, and more hot air, tony kordyban.


course fee: $795
