Abstract: Piezoelectric fan assemblies are provided to provide a conduction path and forced convection for space-limited electronic devices in accordance with embodiments of the present invention. The fan blade of a piezoelectric fan is thermally coupled to the heat source, such as, but not limited to, the fins of a heat sink, the condenser of the heat pipe, and to the thermal mass of a heat spreader or block. The high amplitude resonant vibration of the fan blade causes formation of a high velocity unidirectional flow stream. Maximum airflow occurs on axes of the piezoelectric fan's centerline, relative to both width and height dimensions. Air intake is above and below the swept out plane of the fan blade. The air flow provides forced convection for the fan blade and, secondarily, for the heat source.

TL;DR: In this article, an apparatus is provided for supplying heat required for a reforming reaction through the use of heat pipes adapted to transfer heat from a source to reforming reactants, with a catalyst material being disposed within one of the chambers, such that heat is extracted from a hot fluid and then introduced into the reforming chamber in which a hydrocarbon and steam react in the presence of the catalyst.
Abstract: An apparatus is provided for supplying heat required for a reforming reaction through the use of heat pipes adapted to transfer heat from a source to reforming reactants. Heat pipes extend between two chambers, with a catalyst material being disposed within one of the chambers, such that heat is extracted from a hot fluid and then introduced into the reforming chamber in which a hydrocarbon and steam react in the presence of the catalyst.
