In the current world of heat transfer analysis, most work is performed with numerical simulation. However, there are analysis methods, which are faster and useful for early estimates or even design guidance, that are beneficial to thermal engineers. A recent ECM article [1] mentioned the concept of the critical radius when discussing the cooling/insulating effect of wire … [Read more...]
Strategies for Using Thermal Calculation Methods
Thermal analysis tools available to engineers and scientists offer a wide variety of methods to solve problems. A cursory review of the past decade’s issues of Electronics Cooling magazine can show methods ranging from analytical techniques (such as hand calculations) to spreadsheets to full numerical/computational solutions such as CFD (Computational Fluid Dynamics) and FEA … [Read more...]
Thermal Challenges In LED Cooling
Introduction During the last ten years, developments in LED semiconductors have led to an important change in LED applications from that of luminous indicator to that of illuminator. With LEDs now advancing into several lighting fields, LEDs have become one of the standard methods of producing light, joining more traditional sources such as incandescent, fluorescent and … [Read more...]
