Method and device for processing heat exchanger

A heat exchanger processing method, comprising following steps:

• S100, providing a plurality of microchannel flat tubes, wherein the plurality of the microchannel flat tubes are spaced apart along their thickness direction, and the plurality of the microchannel flat tubes form a flat tube group;
• S200, limiting the flat tube group in a first direction, limiting the flat tube group in a third direction, wherein a length direction of the flat tube group is defined as the first direction, a thickness direction of the flat tube group is defined as the third direction, the first direction is perpendicular to the third direction, and the flat tube group has N installation positions arranged along the first direction, where N is greater than or equal to 2;
• S300, providing a plurality of fins, wherein the fin comprises a plurality of slot holes spaced apart along a length direction of the fin, the slot hole penetrates through the fin along a thickness direction of the fin, the plurality of the fins are spaced apart along the first direction, the plurality of the fins form N fin groups, a length direction of the fin group is parallel to the third direction, and a thickness direction of the fin group is parallel to the first direction;
• S400, defining a second direction perpendicular to the first direction and the third direction, wherein a width direction of the flat tube group is parallel to the second direction, moving one fin group to a position opposite to one installation position of the flat tube group in the second direction, so that a width direction of the slot hole of the fin is parallel to the width direction of the flat tube group;
• S500, moving the one fin group along the second direction to make the one fin group contact with the flat tube group, and to insert the plurality of the microchannel flat tubes into the plurality of the slot holes of the one fin group, with one microchannel flat tube inserted into the plurality of the slot holes arranged along the first direction on the one fin group;
• and
• S600, moving another fin group to a position opposite to another installation position of the flat tube group in the second direction, moving the other fin group along the second direction to make the other fin group contact with the flat tube group, and to insert the plurality of the microchannel flat tubes into the plurality of the slot holes of the other fin group, with one microchannel flat tube inserted into the plurality of the slot holes arranged along the first direction on the other fin group, repeating step S600 until an installation of the N fin groups with the flat tube group is completed;
• or
• S700, moving another fin group and the flat tube group to move the other fin group to a position opposite to another installation position of the flat tube group in the second direction, moving the other fin group along the second direction to make the other fin group contact with the flat tube group, and to insert the plurality of the microchannel flat tubes into the plurality of the slot holes of the other fin group, with one microchannel flat tube inserted into the plurality of the slot holes arranged along the first direction on the other fin group, repeating step S700 until an installation of the N fin groups with the flat tube group is completed.
