Welcome to the official website of the Sauna™ thermal modeling software package. The Sauna software package can be used to simulate a wide variety of electronic components and systems, such as heat sinks (heatsinks), circuit boards (PCB's), semiconductor stackups (BGA, QFP), complete enclosures and complex duty cycle transient cooling problems.
The Sauna program is quite easy to use. Complex 3D models are created by combining the "building blocks" of circuit boards, plates, and plates with fins. Heat transfer coefficients for both convection and radiation are calculated automatically. All these powerful features are provided at a very moderate price. Sauna can be run on virtually any contemporary Windows PC. A free evaluation package is available.

not received your updated software, please contact
Technical Support.
14 Sep 06: Sauna was featured
in Machine Design magazine, see
Sauna software review in Machine Design.
Also, there are useful
papers in the Papers/Articles
section. "Optimum fin spacing for fan-cooled heat sinks."
explains that the optimum fin spacing is primarily a
function of the flow length of the heat sink. The paper also
shows that expensive heat sinks with closely spaced fins can
provide excellent performance, provided that the fin spacing is
properly matched to the length of the heat sink. The
Papers/Articles section
also contains the paper "Comparing naturally cooled horizontal
baseplate heat sinks with vertical baseplate heat sinks". This
paper has proven to be quite popular, with hundreds of downloads
each month. |
