<P>PROBLEM TO BE SOLVED: To provide a heat exchanger having high heat exchange efficiency and effectively cooling a return fuel. Ž<P>SOLUTION: A refrigerant inlet 42 and a return fuel inlet 46 are disposed on a diagonal line of the heat exchanger 18 when observing the heat exchanger 18 in the arrow P direction, and a refrigerant outlet 44 and a return fuel outlet 48 are also disposed on the diagonal line. The flowing direction of the refrigerant and the flowing direction of the return fuel are entirely opposite each other. As prescribed temperature difference is generated from the return fuel inlet 46 to the return fuel outlet 48 on the basis of temperature difference between the return fuel and the refrigerant along a return fuel flow channel 36, the return fuel is effectively cooled from an initial period to a termination period of the cooling of the return fuel.
