Abstract
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.
