热交换器
摘要：
在构成为能够在三种流体间进行热交换的复合型的热交换器中，在冷媒用管(12a)及冷却水用管(43a)的周围形成供外部气体流通的外部气体通路(70a)，在外部气体通路(70a)中配置有促进冷媒与外部气体的热交换以及冷却水与外部气体的热交换的外部翅片(70b)。外部翅片(70b)具有将冷媒用管(12a)彼此热连接的冷媒侧热连接部(71b)和将冷媒用管(12a)与冷却水用管(43a)热连接的冷却水侧热连接部(72b)。在由形成冷媒流动的最下游侧的通道即最终通道的最下游侧冷媒用管(121a)构成的第一芯部(701)中，冷媒侧热连接部(71b)的个数比冷却水侧热连接部(72b)的个数多。由此，抑制作为热交换器整体的热交换性能的降低。
摘要（英）：

In a composite-type heat exchanger capable of exchanging heat among three types of fluids, an outside air passage is provided in a periphery of refrigerant tubes and coolant tubes, and the outside air passage includes outer fins that promote heat exchange among a refrigerant, an outside air and a coolant. The outer fins include refrigerant side heat connecting portions configured to thermally connect the refrigerant tubes, and coolant side heat connecting portions configured to thermally connect the refrigerant tubes and the coolant tubes. In a first core portion including most downstream refrigerant tubes which constitute a final path, which is the most downstream side path in a direction of the refrigerant flow, the refrigerant side heat connecting portions is larger in number than the coolant side heat connecting portions.
