Abstract
A fluid heater apparatus supplies heat to wash fluid via a flow path in a thermally conductive body. A heat source is disposed in the thermally conductive body for imparting heat to the body. Fluid flowing through the thermally conductive body in a flow path enveloping the heat source to absorb heat from the body. A seal member and a metal plate are fixed to one surface of the thermal body. A high thermally conductive pad is disposed between a printed circuit board carrying a control with heat generating switch elements. The pad conducts heat generated by control switching elements to the plate to reduce the temperature differential between the plate and the thermally conductive body to balance the temperature of the heater apparatus.
