Introduction Industry power trends and a global push for sustainability are leading decision-makers and data center operations groups to consider alternatives to traditional air cooling. Two key industry trends are driving alternative cooling solutions. First, powers at the chip level are increasing [1,2]. Just a couple of years ago, server CPU and GPU power levels were … [Read more...]
Rapid and Accurate Analytical Model for Predicting Axial Fan Performance in Electronics Cooling
Introduction Forced air cooling remains essential for dissipating the heat generated by high-power-density devices in modern electronics [1]. Axial fans are widely used in information technology, telecommunications, automotive, and aerospace applications for air cooling. The aerodynamic performance (P-Q) curve of fans is essential for designing and optimizing air … [Read more...]
Advanced Cooling System for Modular Electronics Thermal Management
Introduction Modern electronics are rapidly evolving to meet high-computing needs while shrinking in size resulting in large heat fluxes that must be removed for safe operation. Figure 1 shows a schematic of a generic electronics cooling system with representative heat transfer pathway from a chip (heat source) to a cold plate (heat sink) via heat spreaders and card retainers … [Read more...]
Calculating Thermal Design Power for Mobile Consumer Electronics – Part 2
Overview Thermal Design Power (TDP) is a term commonly used in the thermal management of consumer electronics. While the usage of this terminology may vary across the industry, it commonly refers to the amount of power that a device may dissipate indefinitely, in a given thermal environment, without exceeding the temperature limits of the device. The TDP for a consumer … [Read more...]
