1. A fuel cooling apparatus for cooling a fuel flowing through a fuel pipe connected to an engine, the fuel cooling apparatus comprising:
a fuel cooling pipe having an inner circumferential surface and a hermetically sealed space formed therein; a heat pipe allowing a working medium to flow therein, the heat pipe including:
i) an evaporation region inserted into the hermetically sealed space of the fuel cooling pipe so that a fuel passage is formed between the evaporation region and the inner circumferential surface of the fuel cooling pipe, the evaporation region being configured to evaporate the working medium by heat exchange with a fuel flowing through the fuel passage,ii) a condensation region configured to condense the working medium evaporated at the evaporation region, the condensation region being arranged outside of the fuel cooling pipe, andiii) an adiabatic region adiabatically connecting the evaporation region and the condensation region to each other; a fuel inlet port configured to introduce the fuel into the fuel passage of the fuel cooling pipe from the fuel pipe; and a fuel outlet port configured to return the fuel that has flowed through the fuel passage in the fuel cooling pipe to the fuel pipe. |
