Abstract
A micro-combustion power system is disclosed. The invention is comprised of a housing that further comprises two flow path volumes, each having generally opposing flow path directions and each generally having opposing configurations.
Each flow path volume comprises a pre-heating volume having at least one pre-heating heat exchange structure. Each flow path volume further comprises a combustion volume having a combustion means or structure such as a catalytic material disposed therein Further, each flow path volume comprise a post-combustion volume having at least one post-combustion heat exchange structure.
One or more thermoelectric generator means is in thermal communication with at least one of the combustion volumes whereby thermal energy generated by an air/fuel catalytic reaction in the combustion volume is transferred to the thermoelectric generator to convert same to electrical energy for use by an external circuit.
A novel element of the invention relates to the opposing configuration and opposing flow path directions of the respective flow path volumes. The pre-heating heat exchange structure in the first flow path volume and the opposing post-combustion heat exchange structure are comprised of a shared, thermally conductive structure and material. In this embodiment, waste heat from the exhaust gas in the post-combustion chamber is thermally transferred to the opposing pre-heating volume to heat the air/fuel mixture therein to a suitable pre-combustion temperature to take advantage of waste heat while better managing thermal/cooling issues of the device during operation.
