Co-authored by: Nitesh Kumar Sardana, Susyamala Pavan Kumar Busam, Dr. Laxmidhar Biswal Robert Bosch Engineering and Business Solution Pvt. Ltd. Abstract The market demand for lightweight and cost effective electronic products with multi-functional operations leads to the introduction of plastic housing and high current density on board. In general, automotive electronic … [Read more...]
Simulate electronics cooling strategies to design products more effectively
Sponsored by ANSYS Determine the Thermal Signature of an Electronic System As electronic devices become smaller, denser and faster, the structural and thermal integrity of their electronic packages and printed circuit boards (PCBs) becomes more critical. Heat affects the performance and reliability of integrated circuits (ICs) and may cause failure. Keep things running … [Read more...]
Computational Modeling of a Novel End-of-Aisle Close-Coupled Cooling Solution
Data centers are mostly managed by overly conservative thermal management approaches [1]. The typical thermal solution for data centers is perimeter computer room air handlers (CRAH). The traditional cooling method includes supplying air through raised floor plenum that is blown by the CRAH blowers, and the chassis fans, typically located at the rear end of the IT equipment, … [Read more...]
The Problem with Effective Thermal Conductivity
Simply stated, the problem with the use of volume weighted, effective thermal conductivity, kvw, in the thermal modeling of a printed circuit board (PCB), is inaccuracy. In this paper, we show how using kvw can lead to serious errors in the prediction of PCB temperatures. We recommend two, related, alternative procedures that provide greater … [Read more...]
A Brief Overview of Thermal Management in Printed Electronics
Editor’s Note: This is the first in a series of articles to appear in Electronics Cooling addressing emerging areas for electronics thermal management. Printed electronics (PE) is one of the key enabling technologies of many electronic products that we take for granted today, not just in functional feasibility but also in cost that seems to be on a continuous downward trend. … [Read more...]
