Five basic steps when designing for a cooling fan for thermal management

Posted on May 20, 2010 by | 1 comment

As alot of readers can probably tell this is fan week here at ATS’s thermal blog,  so we’re paying some special attention this week to our thermal management pals that move air over our heat sinks: fans and blowers.

Comair Rotron has produced a very succinct and helpful application note on the concept of forced convection cooling. In summary they cover:

  • Five basic steps when designing for a cooling fan
  • What forced convection cooling is
  • A diagram to show how it works

Comair Rotron’s piece is to the point and well worth a visit to refresh the experienced engineer and introduce those who are new to forced convection cooling in thermal management, have a read here at this link: Introduction Forced Convection Cooling

And before I forget, ATS’s thermal consulting team is ready to help you with PCB optimization for thermal management, best fan choice for your application, and designing an overall thermal management solution, for more information, please visit our Thermal Consulting Services Page or email us via our handy Consulting Application Form

How to use fan trays in electronic enclosures for thermal management; an ATS Thermal Labs “how to” white paper

Posted on May 17, 2010 by | Leave a comment

While heat sinks do a terrific job of moving heat from a hot chip, cool air (or another moving liquid) is very helpful to move that heat off the chip and out of the system. Individual fans are one way to approach this problem. Another is by use of a fan tray.

A fan tray is an array of fans put together in a removable tray of some kind. There are various types and configurations based on whether you need to move air for a computer server, telecomm central office equipment or medical equipment. Fan trays are very helpful in developing a system level thermal management solution.

While on the surface of it, a fan tray appears to be no more than a number of fans placed in a frame there is actually quite a bit more there. From the kinds of fans, to the circuitry used to control them, fan trays are really an air moving system that, when engineered right, can bring real benefit.

ATS’s Thermal white paper will give you a basic sense for what’s involved, so click to it at our site now, “How to use fan trays in electronic enclosures; an ATS Thermal Labs “how to” white paper.
