ABSTRACT:
An electric fluid heating device for heating comparatively small amounts of a fluid mdium, particularly for dental purposes, is characterized in that an operable controllable semiconductor, such as a transistor, is used as the heating element. The fluid heating device includes a metallic casing provided with a fluid heating chamber having a fluid inlet and outlet. The semiconductor is seated in a recess in the casing in heat exchange relation with the chamber. A temperature responsive control circuit including a PTC resistor in heat exchange relationship with the chamber is provided for regulating the current flowing through the semiconductor and thus the heat output thereof. The casing is made in two parts to permit a damaged smiconductor to be easily removed and replaced.
