Abstract: The present invention relates to a structure of a fuel-heater for a diesel vehicle mounted on the top of a fuel-heater so as to heat fuel, which has flowed in from upside, with a PTC device and discharge the fuel to a fuel filter at a lower side. The structure of a fuel-heater for a diesel vehicle according to the present invention comprises: a PTC device mounted between plates arranged at upper and lower sides and generating heat by the application of power; an upper housing combined with the upper side of the PTC device, and having an outer wall surface part and an inner wall surface part protruding downward, wherein the inner wall surface part is separated inward from the outer wall surface part; and a lower housing combined with the upper housing at the lower side of the PTC device, and having a middle wall surface part protruding upward to be advanced between the outer wall surface part and the inner wall surface part. The upper housing has an inflow hole for introducing the fuel. An opened flow path is formed between the inner wall surface part and the middle wall surface part and between the outer wall surface part and the middle wall surface part so as to make the fuel flow. The present invention can be formed in the shape of a ring because an upper plate, a lower plate and a planar plate, which are arranged below and above the PTC device, can be mounted on the lower housing. Therefore, the present invention can dissipate heat generated by the PTC device efficiently. The present invention can reduce the flowing pressure loss of the fuel and can increase heat exchanging efficiency by forming a flow path for passing the fuel in a vertically trembling shape.
