Title:
FLAT TUBE AND HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2020/134491
Kind Code:
A1
Abstract:
The present application provides a flat tube and a heat exchanger. The flat tube comprises a middle tube segment and narrowed opening connection segments located at two ends of the middle tube segment, the width of the narrowed opening connection segments being less than the width of the middle tube segment, a transition connection segment being provided between each narrowed opening connection segment and the middle tube segment, and a fastening and positioning part being provided on the transition connection segment. As the transition connection segment of the flat tube in the present application is provided with a fastening and positioning part, the fastening and positioning part has the effect of local reinforcement, ensuring that the joint position of an end portion of the flat tube and a manifold slot can withstand a high pressure, satisfying the pressure resistance requirement for a heat exchanger in the refrigeration industry.
