Abstract
Apparatus and method for heating liquids, e.g. diesel fuel, by means of a conductive polymer heater which does not have an insulating jacket, so that there is direct physical contact between the liquid and electrically conductive parts of the heater. This results in improved heat transfer to the liquid. The unjacketed heater comprises a pair of elongate spaced electrodes embedded in an elongated strip of a conductive polymer, such as cross-linked polyvinylidene fluoride, which exhibits PTC behavior. The heater is positioned in a container through which diesel fuel to be heated flows from an entry port to an exit port. The exterior surface of the polymer strip is exposed and is directly contacted by the flowing diesel fuel.
