A device for cooling fuel for an internal combustion engine, includes a heat pipe, which includes an evaporation zone and a condensation zone. To decrease the amount of gaseous hydrocarbons conducted into an activated carbon filter of a tank ventilation device of a tank of the internal combustion engine, and thereby avoid undesired bleed-emission or an enlargement of the activated carbon filer, the evaporation zone of the heat pipe is in thermal contact with fuel vapors, to condense part of the fuel vapors before the hydrocarbons contained therein can enter the activated carbon filter.
