A noteworthy trend in data centers is to reduce the power consumption of cooling facilities by increasing the supplied temperature to IT services, thereby requiring less work within the cooling facility to provide the targeted temperature. This will result in lower overall power consumption and higher computational effectiveness. However, higher inlet water temperature to the … [Read more...]
Balancing Local Versus Global Cooling Requirements
When you’re planning how to solve the ongoing problem of keeping things cool enough, it’s easy to mentally blur the lines between hot components and hot boxes. The difficulty is that the solution for one of these may not be adequate or appropriate for the other. Here’s the situation: in most systems, the heat sources are not distributed uniformly across the circuit board … [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...]
Comparison of HPC/Telecom Data Center Cooling Methods by Operating and Capital Expense
INTRODUCTIONCurrent 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...]
