A heat pipe has an embedded wick structure that maximizes capillary pumping capability. Heat from attached devices such as integrated circuits evaporates working fluid in the heat pipe. The vapor cools and condenses on a heat dissipation surface. The condensate collects in the wick ...http://www.google.se/patents/US5769154?utm_source=gb-gplus-sharePatent US5769154 - Heat pipe with embedded wick structure
