<p>PURPOSE: A heat exchanger for a vehicle is provided to improve heat exchange performance through a stepped inner surface of a header tank. CONSTITUTION: A heat exchanger for a vehicle comprises a first tank(111), a second tank(112), a third tank, and a fourth tank. Refrigerant flows through an inlet pipe(115) into the first tank. The refrigerant within the first tank flows through tubes(120) into the second tank. The third tank is connected to the second tank. The refrigerant flows through the tubes from the third tank into the fourth tank and then is discharged to outside through a discharge pipe. The internal width of the first, the third, and the fourth tank differs from one another by stepped inner surfaces of the first, the third, and the fourth tank.</p> |
