Abstract: A microchannel type heat exchanger is provided. The heat exchanger may include a first heat exchanger and a second heat exchanger, in which a plurality of flat tube may be provided. The heat exchanger may include a first path defined in a first portion of the plurality of flat tubes provided in the first heat exchanger, the first path being configured such that a refrigerant flows in a first direction, a second path defined in a second portion of the plurality of flat tubes provided in the first heat exchanger, the first path being configured such that the refrigerant, supplied from the first path, flows in a second direction opposite to the first direction, a third path defined in a remaining portion of the plurality of flat tubes provided in the first heat exchanger and a portion of the plurality of flat tubes provided in the second heat exchanger, the third path being configured such that the refrigerant, supplied from the second path, flows in a third direction opposite to the second direction, and a fourth path defined in a remaining portion of the plurality of flat tubes provided in the second heat exchanger, the fourth path being configured such that the refrigerant, supplied from the third path, flows in a fourth direction opposite to the third direction.

Abstract translation: 提供了一种微通道式热交换器。 热交换器可以包括第一热交换器和第二热交换器，其中可以设置多个扁平管。 热交换器可以包括限定在设置在第一热交换器中的多个扁平管的第一部分中的第一路径，第一路径被配置为使得制冷剂沿第一方向流动，第二路径限定在第二路径的第二部分 设置在第一热交换器中的多个扁平管，第一路径构造成使得从第一路径供应的制冷剂在与第一方向相反的第二方向上流动，在多个剩余部分中限定的第三路径 设置在所述第一热交换器中的扁平管和设置在所述第二热交换器中的所述多个扁平管的一部分，所述第三路径被构造成使得从所述第二路径供应的制冷剂在与所述第二热交换器相反的第三方向上流动 方向和限定在设置在第二热交换器中的多个扁平管的剩余部分中的第四路径，第四路径被配置为使得re 从第三路径供给的纤维束沿与第三方向相反的第四方向流动。
