ATS Thermal Webinar: Thermal Management of a Datacenter August 12, 2PM

Here’s an open invite to all our readers to our next webinar, “Thermal Management of a Data Center”. We’ll be hosting it on August 12, 2010 at 2PM EST. Our webinars are no charge and taught by our R&D staff to keep them light on “mareticture” and heavy on the kind of technical details engineers and others can use to develop effective thermal management solutions.

Data Centers are effectively large scale systems composed of the components of racks of computers. Novel approaches to cooling data centers of various sizes are being undertaken today to obtain the best and most green cooling possible. This vertical webinar will consider approaches for small, medium and large scale data centers to achieve a given data centers cooling goals.

Thermal management of a datacenter through the use of a hot aisle/cold aisle strategy

Data center cooling and thermal management is on the forefront of everyone’s minds. Whether you want to call that data center a central office, as Verizon does, or a something else, it’s all about big computing centers housing hot equipment. So hot in fact that Verizon even issued VZ.TPR.9208, its own specification, to insure OEM equipment is thermally efficient.

Data center managers have a variety of strategies at their disposal to implement the best thermal management approach; one is creating a hot aisle/cold aisle setup. Processor magazine ran a terrific article on this topic that is well worth a read. Among their key points:

  1. Alternating hot aisles and cold aisles is essential to proper thermal management in a data center, as it’s crucial to measure air temperature at the server, storage, and network level as well as ambient temperatures.
  2. One size doesn’t fit all for hot and cold aisles, and what might work in one area may not in another, making planning an important part of implementation.
  3. The cost of a hot and cold aisle setup varies depending on complexity and size and could run to the tens of thousands of dollars if consultants and new equipment are involved. But in general, containment systems and gear such as thermal curtains can make a strategy more affordable.

The article does a good job of thinking through key points on how to use this approach effectively to effective thermal management and you can read it at this link at Processor Magazine: “Create A Hot Aisle/ Cold Aisle Setup”.

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

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:

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

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 maxiGRIP is flame retardent and our engineers prove it on video!

From time to time ATS engineers are asked if maxiGRIP, our patented heat sink attach technology that allow phase change interface material to be properly used, can resist  high heat.

Would ATS design something that didn’t pass every possible, necessary rating – never.  We can’t bring ourselves to design it poorly.  We know that thermal management is not just an afterthought and that it can make or break a system performance.

So, to prove our point, we’ve produced this short video on maxiGRIP and a simple flame test.  It’s a simple video of what happens when you use heat stress maxiGRIP.  Enjoy!  I think you can guess the outcome: .
