Abstract:
1. A heater apparatus for heating fluid, the heater apparatus comprising: a thermally conductive mass; heating means, thermally coupled to the thermally conductive mass, for imparting heat to the thermally conductive mass; a fluid flow path formed in the mass between an inlet and an outlet, the fluid flow path coupled in heat transfer relation to the heating means so that fluid in the fluid flow path absorbs heat from the thermally conductive mass; control means, connected to the heating means, for activating the heating means, the control means including a printed circuit board; a thermally conductive medium coupled in heat transfer relationship between at least a portion of the control means and the thermally conductive mass to minimize a temperature differential between the thermally conductive mass and the ambient environment, the thermally conductive medium disposed in contact between the printed circuit board and the thermally conductive mass; and a thermal insulating member disposed between the thermally conductive mass and the thermally conductive medium.
