Transparent heat-spreader for optoelectronic applications

摘要

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.

主权项

1. An optoelectronic device comprising an optoelectronic chip, a transparent fluid in thermal contact with the chip, an optical system coupling said chip to an aperture larger than the chip that allows the passage of light, and a transparent cover over said aperture, said cover with a fluid passage communicating with said chip and containing said fluid such as to establish circulation conveying heat from said chip to said cover.
