A heat exchanger includes a plurality of flat tubes, a header part, and a guide part. An interior of the header part is partitioned into first and second spaces. One end of each of the tubes is connected to the first space. The guide part has a guide space positioned below the first space. The guide space communicates with the first space via an ascending opening. The first and second spaces communicate with each other via upper and lower communication ports provided within upper and lower sides of the header part, respectively. When the heat exchanger is viewed from above after installation, the tubes and the ascending opening have an area of overlap, and the ascending opening and a space where the lower communication port is extended do not overlap or have an area of overlap that is up to 50% of the ascending opening.

A refrigerant diverter diverts inflowing refrigerant and to cause the refrigerant to flow out to a downstream side. The refrigerant diverter includes a vertically extending diverter case, and a vertically extending rod-shaped rod member disposed inside the diverter case. The diverter case has a plurality of diverting channels disposed along a circumferential direction, a diverting space arranged to guide the refrigerant to the diverting channels, and a plurality of expelling spaces that communicate with the diverting space through the diverting channels, the expelling spaces being disposed along a vertical direction. The diverting channels are configured from a plurality of holes extending in a longitudinal direction of the rod member and integrally formed in the rod member.

The present invention discloses a fin and a micro-channel heat exchanger. A retractable fin in a bending region of the micro-channel heat exchanger comprises a plurality of fin unit sections which are sequentially connected to form a corrugated structure, each fin unit section comprises a first straight section and an arc top section, and a retractable section which is deformed due to stretching/squeezing in a bending process of the micro-channel heat exchanger is provided between the first straight section and the arc top section. The retractable sections of the retractable fin are gradually straightened in the bending process of the micro-channel heat exchanger, included angles between the retractable sections and adjacent straight sections gradually become small, and this thereby ensures that the retractable fin in the bending region is not stretch-broken.
