Nanotech Yields Major Advance in Heat Transfer, Cooling Technologies Researchers at Oregon State University and the Pacific Northwest National Laboratory have discovered a new way to apply nanostructure coatings to make heat transfer far more efficient, with important potential applications to high-tech devices as well as the conventional heating and cooling industry. These … [Read more...]
Energy Efficiency Reshapes Thermal Management Challenges
Electronic equipment manufacturers are increasingly more focused on achieving high efficiency levels for their circuit designs in response to global concerns about the impact on the environment. However, the thermal benefits of high efficiency circuit design are often offset by the heat generated due to the trend for more densely packed components. Factors such as limited … [Read more...]
Heat Conducting Graphene Could Cool Electronics
Multiple layers of graphene show strong heat conducting properties that can be harnessed in removing dissipated heat from electronic devices, a team of scientists from the University of California reported in a recently published paper in the journal Nature Materials. Having previously shown that graphene — a two-dimensional layer of carbon atoms packed in a honeycomb structure … [Read more...]
Thermoelectricity: Turning Temperature Differences Directly into Electricity
The fundamental problem in creating efficient thermoelectric materials is that they need to be good at conducting electricity, but not at conducting thermal energy, say Massachusetts Institute of Technology (MIT) researchers. That way, one side can get hot while the other gets cold, instead of the material quickly equalizing the temperature. But in most materials, electrical … [Read more...]
High-Performance Thermal Putty
Fujipoly has released SARCON XR-Um-Al, a thermal interface silicone putty. The gap filler compound’s putty-like consistency contributes to the material’s low contact and thermal resistance while maintaining a thermal conductivity of 17 watt/m-k. SARCON XR-Um-Al is manufactured with a thin aluminum carrier film for customer-friendly application. The low adhesion aluminum barrier … [Read more...]
