Enhancing Heat Sink Performance Using Thermoelectric Coolers

With the increase in the power dissipation of components and the parallel reduction of their size, engineers and researchers across the globe have been predicting that the era of air cooling might come to an end. Even though in some applications, with very high power dissipations such as IGBTs, air cooling may not be adequate and liquid cooling is a must; air cooling will continue to be the first choice for most electronic cooling applications for many years to come. Advances in air cooling continue to extend its use and the implementation of thermoelectric coolers (TECs) in heat sink applications is one such effort.

Immersion Liquid Cooling for Servers in Data Centers

Data center designers and operators have invented many ways to improve the data center’s thermal efficiency, such as optimizing the rack layout and air conditioner location, separating cold aisles and hot aisles, optimizing the configuration of pipes and cables in under-floor plenum, introducing liquid cooling to high-power severs. While the above methods can improve the data center heat load management, they cannot dramatically reduce the Power Usage Effectiveness (PUE). This article reviews two relatively new solutions: active single-phase immersion cooling technology proposed by Green Revolution Cooling (GRC) and a passive two-phase immersion cooling technology proposed by the 3M Company.

Industry Developments: Piezoelectric Cooling

Piezoelectric fans and jets must overcome various materials, thermal and mechanical challenges to become widely used in electronics cooling, but because they consume just 1/150 of the electricity of circular fans, run with little noise and have no parts that will wear out, they remain of great interest. In this article, a number of issues are addressed, including the inverse effect of the piezoelectric phenomena and dual piezoelectric cooling jets.

Technology Review: Innovative Cold Plate Designs, 2007 – 2012

In this issue our spotlight is on innovative cold plate designs. There is much discussion about its deployment in the electronics industry, and these patents show some of the salient features that are the focus of different inventors.

Give us 60 minutes and we’ll give you a cooler datacenter!

Give us 60 minutes and we’ll give you a cooler datacenter!  That’s right, our webinar on October 27, “Tools and Techniques for the Thermal Management of Small, Medium and Large Scale Data Centers ” will teach you:

  1. How to consider your datacenter like a system for your thermal management strategy
  2. Do you approach cooling a small, medium or large scale datacenter differently or the same?
  3. Are you focusing on the most critical cooling goals for your datacenter or are you chasing the wrong goals and watching heat and power usage spiral?

We’ll answer these questions and more at our free Webinar, “Tools and Techniques for the Thermal Management of Small, Medium and Large Scale Data Centers ”

Next Generation Tools give Data Centers New Strategies for Thermal Management

Todd Schneider over at Electrorack has penned an article on some new approaches to thermal management in the data center. Among the topics Tom covers:

  • An update on metrics being used to determine facility efficiency
  • What’s behind the pressure on data center managers to comply with Go Green initiatives for power usage
  • Discussion of different solutions including: air side solutions, aisle containment solutions, active and passive ducted containment, water-side refrigerant and rear-door exchangers

Todd’s article is well worth a read to help in thinking through what might be next in your data center thermal management strategy. You can read the entire article at Data Center Knowledge by clicking through to this link: “Combatting Thermal Issues with Next-Gen Tools

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”.

Thermal Management of a Data Center; an ATS Webinar on August 12, 2PM

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.

ATS Webinars are light on marchitecture but heavy on thermal engineering principles and practice. Taught by our R&D staff, some of whom have taught at RPI and Northeastern University, we invite you to attend this free webinar by registering at this link: Thermal Management of a Data Center
