Introduction Thermal management is a critical issue in high-power laser diode and LED packages, and microprocessor units [1, 2]. Reliability and long life time of electronic packages call not only for materials with high thermal conductivity but also a coefficient of thermal expansion (CTE) matching to that of semiconductors. The thermal expansion of the heat sink material in … [Read more...]

A Cryocooler In Your Laptop Computer? Maybe…
Introduction A review of the technical and market impediments overcome in the development and eventual acceptance of cryocoolers for space-borne applications may shine light on the prospects for the use of such mechanical refrigeration systems in more widespread commercial uses. This premise is explored by first reviewing space cooler development history, then considering some … [Read more...]
