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...]

Thermal Challenges with Wearable and Implantable Electronic Devices in Healthcare
INTRODUCTION Traditionally, medical science has depended on a variety of diagnostic tests administered by medical personnel to either detect the onset of an illness or to monitor its progress. More recently, this focus has been supplemented by a strategy of health maintenance and disease prevention. Both of these strategies benefit from the frequent testing of individuals. Of … [Read more...]
Thermal Management and Safety Regulation of Smart Watches
ABSTRACT A smartwatch is one of the most popular wearable devices now. Along with battery life and security, thermal safety is the most common concern. We show how to meet ergonomic standards for users and predict thermal performance in typical scenarios. Thermal simulation software applied at the design stage can provide guidance on the use of heat-spreading materials and … [Read more...]
