Abstract
A bent heat exchanger and a method for manufacturing the same are provided. The bent heat exchanger includes: a first header and a second header spaced apart from each other, a plurality of flat tubes and a plurality of fins. A plurality of flat tubes are disposed between the first header and the second header, two ends of each flat tube are connected with the first header and the second header respectively. Each flat tube has straight segments and a bent segment between the straight segments, the bent segment is twisted by a predetermined angle relative to the straight segment around a longitudinal direction of the flat tube. The bent segments of a plurality of the flat tubes form a bent segment row extending in a thickness direction of the flat tube. A plurality of the flat tubes are divided into a plurality of groups.
