ATS Fan Characterization Module Takes Guesswork out of Verifying Chassis Fan and Computer Cooling Fan Performance

FCM-100 Chassis Fan Characterization ModuleThe FCM-100 is perfect addition to any lab where you need to characterize fans for thermal performance. So, whether the fan is used for:

  • CPU Cooling
  • Chassis Cooling
  • Enclosure Cooling
  • Telecomm Rack Cooling

You can use the FCM-100 to characterize your fans.

  • Designed to test and characterize fans of various sizes and performance outputs
  • Features four (4) removable perforated flow restriction plates to allow the user to control the pressure drop through the module for fans under testing
  • Used in conjunction with pressure and velocity measurement equipment to develop fan curves (ΔP vs. Flow rate) that can be used to verify fan manufacturer data or to characterize fans of unknown performance

ATS announces reduced cost bundles of thermal instruments

We announced a family of thermal instrument bundles yesteday. We are very excited about this news since it reflects both an ease of choosing the right set of instruments to do thermal analysis but also a lower price point for our instruments.

Choosing the right set of instruments to set up your thermal analysis lab isn’t necessarily like going to Apple and choosing what options you want on your new Macbook Pro. You really have to sort through the various options to get what you need. And our team of engineers has now done that for you to simplify the process. You can read all about it at ATS’s thermal instrument blog here: ATS Announces New Instrument System for Studying Air Flow and Air Temperature

Cutting edge semiconductor cooling news: Nano-coating cools chips four times faster

Many of us at ATS Thermal Labs are on the continued quest to continue to extend air only solutions for the thermal management of electronics.  We’ve invented some remarkable solutions to keep using air mainly because customer’s want it. No one wants to use liquid cooling in their electronic systems if they don’t have to. Such innovations as maxiFLOWTM heat sinks and superGRIPTM heat sink clips that allows phase change thermal interface material to work optimally, were driven by our customer’s demands to keep cooling with air. Soon there may be another tool for the thermal engineer to use: nanoscale coating.

As reported in EE Times:

Nanoscale coatings could boost the efficiency with which heat can be removed from semiconductors and other devices, according to an Army Research Laboratory funded study by researchers at the Pacific Northwest National Laboratory (PNNL) and Oregon State University (OSU).

The industry has known about nano-cooling for some time of course.  Including Intel’s invention of integrating circuits with carbon nano-tubes to enhance thermal management. But nanoscale coating might provide up to a 10x improvement in heat transfer coefficient. Pretty remarkable cooling and one our team is happy to see develop. You can read all about it at EE Times at their article, “Nano-coating cools chips four times faster“.

Thermal Management of High Power Components through Pool Boiling

Boiling and condensation are increasingly employed thermal management methods for high heat flux electronic devices. These heat transfer mechanisms are applied in thermosyphons, heat pipes, vapor chambers and two-phase minichannel and microchannel heat sinks. The fundamental physics behind these devices includes pool boiling, vapor condensation and convection heat transfer. Boiling and condensation processes are affected by device geometry, surface roughness, wall superheat, saturation pressure and fluid properties. Understanding the fundamentals of pool boiling and condensation, and the parameters that affect them, will improve the design of thermal management devices.   To learn more on this topic, ATS has published a white paper that readers can have for free by clicking to qats.com at this link, “Use of Pool Boiling to Thermally Manage High Power Components“

Thermal Computations for Electronic Equipment by Gordon Ellison

At our webinar we broadcast today live from our studios here in Norwood, MA, “Analytical, Computational and Experimental Thermal Analysis of a xTCA Chassis” we mentioned Gordon Ellison as a resource for thermal modeling equations. We wanted to follow up with how to find his material.

Gordon’s book, “Thermal Computations for Electronic Equipment” can be purchased from Amazon.

You can also find an article written by Gordon on “Fan cooled enclosure analysis using a first order method” at Cooling Zone.
