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...]
How My Electronics Should Be Oriented: A Thermal Point of View Study to Understand the Impact of Orientation on Internal Air Temperature
Authored by: Tejas Manohar Kesarkar and Nitesh Kumar Sardana Abstract— Modern day electronics work in varied thermal conditions. The increase in demand of electronics has led to miniaturization, use of plastic housing, and more applications from the existing electronics in the market. The model for analysis consists of multi-layered Cu-FR4 Printed Circuit Board (PCB) … [Read more...]
A Preview of Automotive Electronics Thermal Management: AMAA Symposium 2018
The 22nd International Forum on Advanced Microsystems for Automotive Applications (AMAA 2018) starts this week at Berlin, Germany. This international forum covering the progress in connected, automated, and electrified vehicles this year has the theme “Smart Systems for Clean, Safe and Shared Road Vehicles.” The conference is co-sponsored by EPoSS, the European Technology … [Read more...]
Laser Cooling Evolves to Meet Industrial and Medical Space Constraints
As lasers with higher output power are produced in smaller packages to meet space requirements, the size of external laser chillers must also be reduced, while offering improved cooling and energy efficiency. Higher laser output power in increasingly smaller packages has many benefits in reducing the floor space requirements in production floor, cleanroom, medical … [Read more...]
DCIM And Deepmind, Take 2: AI to Control Google’s Data Center Cooling
Readers of Electronics Cooling will no doubt recall our blog Of Deepmind, DCIM, and Data Center Cooling published two years ago where we highlighted some of the good design practices Google uses to improve (i.e., decrease) Power Usage Effectiveness (PUE) metric in its data centers. In that blog we cited one metric for average PUE that steadily decreased from 1.20 in 2008 to … [Read more...]
