ATS announces free webinar: Methodologies for fan characterization and deployment within a system; 7/22 @ 2PM

Posted on July 6, 2010 | Leave a comment

Exponential increases in power dissipation are forcing engineers to rely more on cooling fans as the solution to their thermal management challenges. But fans are also common points of failure within a system. As the choice and use of cooling fans become critical to system functionality, knowledge of fan characterization is essential. Participants will be provided with solid methodologies for characterizing fans and deploying them within a system.

Tony Koryban Mail Bag Archives: For my fan design, is there a way I can calculate the new operating point at reduced fan speed? And how much does the audible noise go down with reduced fan speed?

Posted on July 2, 2010 | Leave a comment

Tony Koryban’s mail bag archive today addresses a problem whereby the engineer only needs it to go full blast when the room temperature goes over 40 degrees C. Here’s the question:

I don’t need it to run at full capacity. I only need it to go full blast when the room temperature goes over 40 degrees C. Maybe I could put in a speed controller to slow the fan down when I don’t need all that air, and a thermal sensor to tell it to speed up again if the room gets hot. Slowing the fan down will definitely make it quieter. Before I do that, is there a way I can calculate the new operating point at reduced fan speed? And how much does the audible noise go down with reduced fan speed?

And Tony has his usually full, practical and humorous answer of course. Read Tony’s solution to this fan fun at Tony Koryban’s Mail Bag Archive.

What are Fan Laws and how do you use them in thermal management design?

Posted on May 21, 2010 | Leave a comment

During a product’s life cycle a redesign may be carried out which replaces older components with new, higher powered ones. Due to the resulting higher heat flux, increased thermal management is often needed to maintain adequate component junction temperatures and reduce temperature rise within the system.  Fan Laws are useful mathematical tools to understand, compare and contrast different fan approaches.  Using Fan Laws before choosing a fan can help engineers to make solid choices to reduce cost, experimentation and time to market.  ATS’s five-page presentation on Fan Laws for thermal management which includes examples on how to use them, is a good introduction to this important engineering tool:
