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
ATS, Inc. is announcing a new “on-demand” webinar from our thermal engineering team, “Methodologies for Fan Characterization”. This webinar is ready for download and listening 24 hours day from the ATS web site.
Topics covered include:
- What are the fan types and points of application?
- Understanding how fans operate and the effect of bypass flow on their operation
- Fan selection
- Fan assemblies and their implementation
- Use of fan laws for sizing
- Managing acoustic noise
- Fan characterization
To take part in this webinar, just click to our site to reach the webinar at: Methodologies for Fan Characterization
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.
