Title: Transparent heat-spreader for optoelectronic applications

Abstract

An optoelectronic cooling system is equally applicable to an LED collimator or a photovoltaic solar concentrator. A transparent fluid conveys heat from the optoelectronic chip to a hollow cover over the system aperture. The cooling system can keep a solar concentrator chip at the same temperature as found for a one-sun flat-plate solar cell. Natural convection or forced circulation can operate to convey heat from the chip to the cover.

Conductive heat spreader and heat sink assembly for optical devices

Patent Doany, Fuad Elias; Schultz, Mark

Matching of coefficient of thermal expansion for heat spreaders and carrier die can facilitate optoelectronic die alignment. In one example, an apparatus comprises a carrier die comprising a first coefficient of thermal expansion, two or more optoelectronic die disposed on the carrier die, and a spreader. The spreader can comprise a second material coefficient of thermal expansion matched to the first coefficient of thermal expansion. Additionally, a thermal interface material is disposed between the spreader and the one or more optoelectronic die.
