a second heat exchange portion separated from the first heat exchange portion and performing the heat exchange of a second heat exchange medium with the first heat exchange medium; and a third heat exchange portion for introducing the second heat exchange medium passing through the second heat exchange portion and to perform the heat exchange of the introduced second heat exchange medium with external air, wherein the first to third heat exchange portions are formed in one body integrally to each other. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The integral heat exchanger according to claim 1, further comprising: a first inlet portion formed on one of the first space portion of the first header tank and the third space portion of the second header tank to introduce a first heat exchange medium to the integral heat exchanger; a first outlet portion formed on one of the first space portion of the first header tank and the third space portion of the second header tank to discharge the first heat exchange medium from the integral heat exchanger; a second inlet portion formed on the third space portion of the second header tank to introduce the second heat exchange medium to the heat exchange member; and a second outlet portion formed on the second space portion of the first header tank to discharge the second heat exchange medium from the integral heat exchanger. ### Claim 3 (depends on 2) The integral heat exchanger according to claim 2, wherein the heat exchange member has a shape of a longitudinally elongated pipe. ### Claim 4 (depends on 3) The integral heat exchanger according to claim 3, wherein the heat exchange member includes at least two pipes. ### Claim 5 (depends on 4) The integral heat exchanger according to claim 4, wherein the heat exchange member further comprises a plurality of first pipes having a first sectional shape and a plurality of second pipes having a second sectional shape. ### Claim 6 (depends on 5) The integral heat exchanger according to claim 5, wherein an internal cross-sectional area of each of the second pipes is smaller than an internal cross-sectional area of each of the first pipes. ### Claim 7 (depends on 6) The integral heat exchanger according to claim 6, wherein each of the second pipes has a first concave portion formed inwardly with respect to a peripheral surface of the second pipes, the first concave portion extending along a longitudinal direction of each of the second pipes. ### Claim 8 (depends on 3) The integral heat exchanger according to claim 3, wherein the heat exchange member has a spiral protrusion formed along a peripheral surface of the heat exchange member. ### Claim 9 (depends on 2) The integral heat exchanger according to claim 2, wherein the heat exchange member is a plate, the heat exchange member partitioning an internal space of the second header tank into two sides in the longitudinal direction of the second header tank. ### Claim 10 (depends on 2) The integral heat exchanger according to claim 2, further comprising a third partition member partitioning one side of the second header tank and the second inlet portion.
