Reliability and Thermal Management of LED Luminaire Systems: Higher Reliability Electronics Through the Development of Thermal Management Materials Using the Modified Transient Plane Source Method - (PPT)

摘要

THE HUMAN FACTOR: WHAT DOES EFFUSIVITY RELATE TO? Heat always flows from a hot object to a cold object. Wood is not a good conductor of heat, so it is slow to absorb the heat. Metal has higher "thermal conductivity" so the heat from your hand flows into the metal quickly - creating the sensation of it being cold. C-Therm sensors work like your hand, by rapidly determining the rate of heat flow from one material to another. Like your hands, our sensors supply the heat source and detect the heat flow. They also have no sample size issues, and do not destroy the sample being tested.
