INTRODUCTION Over the last 10 years, there has been a well-documented increase in the energy density of electronic devices. As this energy density has gone up, so has the heat dissipation on electronics packages. In response to this challenge, significant research has taken place to develop chip level cooling systems to meet heat fluxes in excess of 1000W/cm2. As stated … [Read more...]
Thermal Material Provides Both Compressibility and Conformability with Phase-Change Ability
AI Technology, Inc. has released COOL-PAD™ CPR7154, a thermal interface material that dispenses like a thermal pad but exhibits characteristics like that of a grease or gel when device temperatures increase to above 45°C. Ideal for use in LEDs, gaming consoles, laptops and desktop computers, COOL-PAD™ CPR7154 is optimized to accommodate large areas with different heights and … [Read more...]
Graphene Improves Copper Film Thermal Conductivity
The placement of a single atomic plane of graphene on the surface of a copper film can significantly increase the film’s thermal conductivity, making the hybrid material ideal for more demanding thermal management applications, according to new research from scientists at the University of Manchester, UK and the University of California-Riverside, U.S. The phenomenon was … [Read more...]
Magnetically-Stimulated Flow Patterns Could Boost Heat Transfer
Magnetically-stimulated fluid flow patterns may offer a new method for handling difficult heat transfer problems by overcoming natural convection limits, according to new research from scientists at Sandia National Laboratories. Convection cooling, which refers to the transfer of heat between two places by the movement of fluids, is often forced in many modern cooling systems … [Read more...]
Nanoscale Pillars May Improve Thermoelectric Materials
Researchers at the University of Colorado Boulder say a new method of improving thermoelectric materials could lead to the development of better solar panels, more energy-efficient cooling equipment and effective devices that could turn waste heat from power plants into electricity. The technique, which involves constructing an array of nanoscale pillars on top of a sheet of … [Read more...]
