Collecting pipe assembly for micro-channel heat exchanger

The invention relates to the technical field of micro-channel heat exchange, and discloses a collecting pipe assembly for a micro-channel heat exchanger, the collecting pipe assembly comprises a micro-channel main body, the micro-channel main body comprises collecting pipes, flat pipes and fins, the symmetrical collecting pipes are arranged on the two sides of the micro-channel main body, and a plurality of continuous and equidistant flat grooves are machined in the inner sides of the collecting pipes and used for assembling the flat pipes; the flat pipe is directly inserted into the flat groove of the collecting pipe through equipment, the cover on the upper side of the collecting pipe can be folded through the hinge, the flat pipe is covered with a boss structure, the boss can reduce gaps of the collecting pipe after the upper cover is tightly covered, and the sealing performance of the device is improved. Compared with an existing micro-channel heat exchanger, the micro-channel heat exchanger with the doub
