1. A method for processing a heat exchanger, comprising:
providing the heat exchanger, wherein the heat exchanger comprises a first tube, a second tube and a plurality of heat exchange tubes, the plurality of heat exchange tubes communicates the first tube with the second tube,
each heat exchange tube comprises a first section, a second section and a bent section, the bent section has a first end connected with the first section and a second end connected with the second section, the bent section of the heat exchange tube comprises a twisted section,
the first sections of the plurality of heat exchange tubes are arranged at intervals along a length direction of the first tube, and the second sections of the plurality of heat exchange tubes are arranged at intervals along the length direction of the first tube,
before processing of the heat exchanger, the bent section of one heat exchange tube is in contact with at least part of the bent section of another heat exchange tube adjacent to the one heat exchange tube in the length direction of the first tube;
placing a pushing member so that at least part of the pushing member contacts at least part of the bent section of at least one heat exchange tube;
moving the pushing member to drive the bent section to rotate by a predetermined angle or move by a predetermined distance relative to the first section connected with the bent section, and/or
moving the bent section of the heat exchange tube so that the bent section rotates by a predetermined angle or moves by a predetermined distance relative to the first section connected with the bent section,
so that after the processing, the bent section of one heat exchange tube is not in contact with the bent section of the heat exchange tube adjacent to the one heat exchange tube in the length direction of the first tube.
