To improve a cooling effect of a refrigerant in a condensation unit 20 of a heat exchanger 10.SOLUTION: An air volume of an airflow flowing through an other-side region 240 in an evaporation unit 22 is larger than an air volume of an airflow flowing through a one-side region 241. An amount of condensed water W1 generated in the other-side region 240 of the evaporation unit 22 is larger than an amount of condensed water W2 generated in the one-side region 241. An other-side region 250 has a larger temperature difference between a refrigerant and the condensed water than that of a one-side region 251. Compared to a case where the amount of condensed water W1 flowing in the other-side area 250 is smaller than the amount of condensed water W2 flowing in the one-side area 251, heat exchange between the refrigerant and the condensed water is performed efficiently.SELECTED DRAWING: Figure 1
【課題】熱交換器10において凝縮部20における冷媒の冷却効果を向上する。【解決手段】蒸発部22において他方側領域240を流れる空気流の風量が、一方側領域241を流れる空気流の風量に比べて多くなっている。蒸発部22のうち他方側領域240に生じる凝縮水W1の水量は、一方側領域241に生じる凝縮水W2の水量に比べて多くなる。他方側領域250は、一方側領域251に比べて、冷媒と凝縮水との温度差が大きくなる。他方側領域250に流れる凝縮水W1の水量が一方側領域251に流れる凝縮水W2の水量に比べて少なくなる場合に比べて冷媒と凝縮水との熱交換を効率的に実施する。【選択図】図1
