Cooling and thermal management are critical to data center reliability. Many organizations see cooling as a differentiating factor in the lifecycle cost of their data center. Recent industry guidelines [1] for data center cooling have suggested energy savings in air-cooled data centers by increasing the temperature of the cooling air. This increase enables two trends: reduced … [Read more...]
Thermal Management of Outdoor Enclosures, Part 5A: Passive PCM Cooling Systems
In Part 1 (Thermal Management of Outdoor Enclosures), key aspects for successful design and development of thermal management systems were covered briefly, among these, cooling device selections and its impact on power, battery back-up and maintenance has therefore become of paramount importance for telecommunications enclosures. These are: Full active systems, like air … [Read more...]
Review of FLIR’s FLIRONE PRO IR Camera
While most of my clients are most interested in EMI mitigation, a few wonder aloud about certain IC temperatures. For that reason, I carry a small IR thermometer in my troubleshooting kit. However, when FLIR announced the FLIRONE PRO module that attaches to iPhones, I was hooked and had to purchase one. The FLIRONE PRO includes a dual camera – one for infrared capture and … [Read more...]
Comparison of HPC/Telecom Data Center Cooling Methods by Operating and Capital Expense
INTRODUCTION Current high-performance computing (HPC) and Telecom trends have shown that the number of transistors per chip has continued to grow in recent years, and data center cabinets have already surpassed 30 kW per cabinet (or 40.4 kW/m2) [1]. It is not an unreasonable assumption to expect that, in accordance with Moore's Law [2], power could double within the next few … [Read more...]
Metal Foam Heat Exchangers
Reticulated Metal Foams (RMF) are cost-effective and ultra-high-performance thermal management materials that can be integrated with electronic devices and modules. RMFs are compatible with DI water, inert fluoro-carbons, jet fuel, and inert gases. STRUCTURE OF RMF There are quite a few ways to fabricate RMF [1], however the investment casting method of … [Read more...]
