Porous thin film heater and method

摘要

A resistance heater for heating fluids including a fluid-permeable porous substrate. An electrically conductive porous thin film is deposited on the porous substrate. An electrical connector coupled to the thin film and adapted to provide an electrical circuit through said thin film to effect heating of said thin film in order to heat a fluid passing through the pours of the thin film and substrate. A method of making and using a resistance heater is also disclosed.
