HEAT-SINK USING CARBON NANO-TUBE

摘要

PURPOSE: A heat-sink using carbon nano-tube is provided to efficiently radiate heat generated from a laser diode and to prevent a damage or a surface separation of the laser diode due to the difference of thermal expansivity by using a carbon nano-tube having a good thermal conductivity. CONSTITUTION: A heat-sink comprises a submount heat-sink fixed with a laser diode, carbon nano-tubes formed on the submount heat-sink, a stem for radiating a heat to the outer connected to the submount heat-sink using a solder having a bad electrical conductivity and having a good thermal conductivity for electrically insulating the contact portion. The submount heat-sink further includes mixed body with a bucky paper using the carbon nano-tubes and an insulating body.
