摘要： Embodiments of this application disclose a flat tube, a multi-channel heat exchanger, and an air conditioning and refrigeration system. The flat tube has n groups of flow channels extending in a length direction of the flat tube, and the n groups of flow channels are distributed to be spaced apart in a width direction of the flat tube; and a flow cross-sectional area of a first group of the flow channels is A1, ..., a flow cross-sectional area of k th group of the flow channels is A k , ..., a flow cross-sectional area of an n th group of the flow channels is An, 1 k ≥ 1.2A k-1 , and k is an integer greater than 1. According to the flat tube in this application, cross-sectional areas of the flow channels inside the flat tube are redesigned so that a flow cross-sectional area of a leeward side region is the largest. In this way, under a frosting condition, a degree of frosting on a windward side can be reduced, thereby reducing frost blockage of a heat exchanger, and further improving heat exchange performance of the heat exchanger under a frosting condition.

摘要： Embodiments of the present disclosure disclose a heat exchanger and a method for processing a heat exchanger. A heat exchange tube of the heat exchanger includes a bent section, a first section and a second section. The bent section includes a section to be bent before bending, and the section to be bent includes a protruding section. The heat exchange tube includes a first face, a second face, a third face and a fourth face. An intersection portion of the first face and the third face is a first side edge. A plane parallel to a length direction of a first header and parallel to a length direction of the first section, and also perpendicular to a width direction of the first section is defined as a first plane before the bent section is bent. In the first plane, a minimum distance from a projection line of a first side edge of the protruding section to a projection line of a first side edge of the first section is H, and a minimum distance from the projection line of the first side edge of the first section to the projection line of the first side edge of another adjacent first section is L, and H≥L. The heat exchanger of the embodiments of the present disclosure reduces the risk of the mutual friction of adjacent bent sections during bending and the accumulation of water and dust during the use of the product, thus improving the reliability of the heat exchange tube.
