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.
