A device for heating fuel for engines. A block (1) has a number of bores (2) through which pass thermal transfer tubes (3, 4) whose diameter is smaller than that of the bores so as to provide annular chambers (5, 6) for the fuel to flow through. Helical bulkheads are arranged inside the chambers (5, 6) between the tubes and the walls of the bore, causing the fuel to follow a helical path around the heating tubes (3, 4). |
