Abstract
A bent heat exchanger is provided. The bent heat exchanger includes: a first header and a second header; a plurality of flat tubes, two ends of the flat tube being connected to the first header and the second header respectively; and fins, each disposed between adjacent flat tubes, extending in a corrugated shape along a length direction of the flat tube. The first header and the second header each have a slot running through a wall thereof and a protrusion arranged to an inner surface of the wall thereof. The protrusion includes an arc portion connected to the edge of the slot, and an extension portion protruding inwards from the arc portion. An arc radius of the arc portion is less than or equal to and greater than 0.6 times a thickness of a wall of the corresponding first header or second header.
