Diesel fuel heater

Image Number 5 for United States Patent #4818842.

An in-line diesel fuel heater including a hollow elongated housing in heat conduction relationship with an electric resistance heater heats diesel fuel flowing through the housing to a temperature above the cloud point of the fuel. The hollow housing contains fins or fibers to create fluid turbulence to increase heat exchange between the fluid and the housing. An analog control circuit uses a positive temperature coefficient (PTC) thermistor to regulate the temperature of the housing at a constant temperature instead of controlling the power based on a measurement of the diesel fuel's temperature.
