Abstract (en)
[origin: US2010078151A1] A heat pipe for transporting heat from light emitting elements includes a sealed body made of a non-porous ceramic, a vapor channel inside the body that extends between two heat transfer locations spaced apart on an exterior surface of the body, a ceramic wick inside the body that extends between the two heat transfer locations, and a working fluid that partially fills the vapor transport channel. In a method of making this heat pipe, the body and wick are desirably formed together as a seamless monolithic structure made of the same ceramic material. Using a ceramic makes the heat pipe corrosion resistant and allows electrical components like LEDs to be mounted directly on the body because the ceramic is a dielectric.
