PROBLEM TO BE SOLVED: To provide a heat exchanger capable of realizing a further unification of blowing-out air temperature.SOLUTION: This invention relates to a heat exchanger [1] formed by overlapping two or more heat exchanging modules [2] in a ventilation direction [X] through which refrigerant flows. Each of the heat exchanging modules comprises a pair of upper and lower header tanks [4, 6] arranged in a vertical spaced-apart relation and a plurality of tubes [8] extending in parallel between the upper and lower header tanks and communicated with each of insides of the upper and lower header tanks at both ends. The plurality of tubes form cores [12] for performing a heat exchanging between the refrigerant and air feeding. Each of the heat exchanging modules comprises at least a split flow module [30] in which the cores are divided into several passes, the refrigerant is divided to flow at the header tanks and there is provided a split-flow core [38] where the split flow refrigerant flows; and a merging module [32] merging the refrigerant passed through the split flow cores at the header tanks and flowed to the cores. The split flow module is positioned at a more downstream side in a ventilation direction than the merging module.SELECTED DRAWING: Figure 6 |
