Abstract
A heat exchanger includes a header and a plurality of heat exchange tubes. The header includes a first tube and a second tube spaced apart from each other. The heat exchange tube includes a first section, a processing section and a second section. The processing section is connected between the first section and the second section. A processing method for a heat exchanger includes: twisting the processing section relative to the first section and the second section in a length direction of the first tube; bending the first section and the second section relative to the processing section; and pushing the processing section by a predetermined distance in the same direction as a direction in which the processing section is twisted.
