Integral heat exchanger

An integral heat exchanger comprising:

• a first header tank and a second header tank disposed in parallel and spaced apart from each other by a distance;
• a first partition member disposed transverse to a longitudinal direction of the first header tank, the first partition member partitioning an inner space of the first header tank into a first space portion and a second space portion;
• a second partition member disposed transverse to a longitudinal direction of the second header tank, the second partition member partitioning an inner space of the second header tank into a third space portion and a fourth space portion;
• a plurality of first tubes connecting the first space portion of the first header tank and the third space portion of the second header tank to form a plurality of first heat exchange medium passages;
• a heat exchange member disposed in the third space portion of the second header tank in the longitudinal direction of the second header tank to form a space through which a second heat exchange medium flows to the fourth space portion;
• a plurality of second tubes connecting the second space portion of the first header tank and the fourth space portion of the second header tank to form a plurality of second heat exchange medium passages;
• and
• a plurality of fins disposed between each of the first tubes and between each of the second tubes.
