PURPOSE: A fuel refrigerator for a vehicle is provided to improve the problems related with the increase of fuel temperature by attaching a fuel refrigerator in a diesel engine having a common rail and to protect a refrigerator and a return line. CONSTITUTION: A fuel refrigerator is formed by composing a fuel pipe of a return line with an aluminum tube(31), bending the aluminum tube on a protection panel(41) in a zigzag form, and installing a heat emission panel having many slits(42). The ends of the aluminum tube are connected to a return line and a fuel tank line. Fuel flowing out by passing through an engine passes the return line, and the temperature of the fuel is increased by high pressure. The temperature of the fuel falls while passing through the refrigerator, and the refrigerated fuel returns to a fuel tank. Therefore, the problems due to the increase of fuel temperature are avoided.
