Heat-Transfer Material for Rapid Removal of Heat from LED Circuit Boards
The U.S. Department of Energy has awarded a small business innovation research (SBIR) grant to Applied Nanotech for $150,000. The grant awarded to Applied Nanotech will be used to research the use of the company’s CarbAl heat-transfer material in high-power LED circuit boards. According to the company, the “CarAl heat transfer material has a unique combination of low density, … [Read more...]
Choosing Adhesives for Withstanding Thermal Cycling Stresses
Many engineers have traditionally designed bonding applications to withstand extreme temperatures using the idea that substrate materials and adhesives with similar coefficients of thermal expansion (CTE) will, at a given temperature, change size at the same rate. However, the difficulty of finding substrates and adhesives that have compatible CTEs and meet all application … [Read more...]
Research on Measuring Nanoscale Thermal Conductance May Increase Cooling Efficiency
A research team at the University of Illinois as Urbana-Champaign (UIUC) has developed a new system for examining and measuring nanoscale thermal conductance at the interface between two materials. The scientists believe that with further refinement, the system can be used to harvest electricity from waste heat, increase cooling efficiency of microelectronic devices and target … [Read more...]
