PROBLEM TO BE SOLVED: To improve heat exchange performance and assemblability of a heat exchanger.SOLUTION: In a heat exchanger 10, a first tank 12 is divided into four first to forth spatial portions 28, 30, 32, 34 by a first horizontal separation wall 24 and a vertical separation wall 26, and a second tank 14 has fifth and sixth spatial portions 40, 42 vertically divided into two by a second horizontal separation wall 38. A single tube 16 having a plurality of flow channels 44 inside thereof, has second and third connecting portions 48, 50 projecting in a longitudinal direction at both end portions, the second connecting portion 48 is connected to the first spatial portion 28 of the first tank 12, and the third connecting portion 50 is connected to the sixth spatial portion 42 of the second tank 14.SELECTED DRAWING: Figure 2 |
