Dave S. Steinberg is the author of Cooling Techniques for Electronic Equipment, 2nd Edition, published by Wiley.
This book covers cooling of electronic equipment in depth. The best feature of the book is the completely worked out examples that Steinberg uses. The reader not only gets the equations, but also sees how they are applied in realistic examples. The only thing that I would have liked to see, but did not, was an example or two dealing more with the cooling of high powered semiconductors (such as the larger IGBTs).
This book is nearly 20 years old and it is still the best reference for connecting the therory and practical examples.
Gift for electronic tinkerer.
