ABSTRACT:
A heating device for fuel or other fluid, in particular to prevent solidification of paraffin constituents in diesel oil, comprises a housing (1) with an inlet (14) and an outlet (15) for the fuel, and a number of metal plates (3, 4) inside the housing. Tablets or heater elements (5) made of a ceramic material with a positive temperature coefficient (PTC) are fastened on the metal plates so that heat and electricity is conducted. To improve the heat transfer one or more turbulators (6; 6a, 6b) are placed between two of the above-mentioned metal plates, (3, 4) provided with PTC tablets. Passages (16, 17) are present to make the infed fuel flow from the inlet (14) over the first metal plate, through a turbulator and over the second metal plate to the outlet (15).
