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...]
Exploring the Limits of Air Cooling
Introduction Heat from electronic devices is an integral part of information processing, not a nuisance that can someday be eliminated. This is a physical principle that is independent of the device of information processing. However, when viewed in the historical perspective, the severity of heat problems has not monotonically increased. It came to the fore some time ago, … [Read more...]
Advances In High-Performance Cooling For Electronics
Introduction The need for new cooling techniques is driven by the continuing increases in power dissipation of electronic parts and systems. In many instances standard techniques cannot achieve the required cooling performance due to physical limitations in heat transfer capabilities. These limitations are principally related to the limited thermal conductivity of air for … [Read more...]
Cooling Solutions In The Past Decade
Introduction In 1995, a typical thermal design engineer was aware that removing heat was not going to get any easier in the next few years. A look back at the past ten years reveals that thermal management remained a challenging field. Fortunately, developments and improvements in thermal management hardware have assisted the electronics packaging community by enabling higher … [Read more...]
