The utility model relates to the technical field of micro-channel aluminum flat pipes, and discloses a micro-channel aluminum flat
pipe variable cross-section fractal channel structure which comprises a
pipe body, a plurality of flow dividing channels are formed in the
pipe body at equal intervals, a plurality of air holes are formed in the front side of the top wall of the pipe body at equal intervals, a first sliding groove is formed in the rear side of the inner wall of each air hole, and a second sliding groove is formed in the rear side of the inner wall of each air hole. A first spring is installed on the inner bottom wall of the first sliding groove, a connecting block is installed at the top end of the first spring, a
rotating disc is fixedly connected to the right side of the connecting block, a plurality of first circular grooves are formed in the pipe body at equal intervals, and the
rotating disc is in sliding connection with the first circular grooves. According to the utility model, the movement of the turntable drives the closing blade to move through the sliding chute II and the sliding block, and meanwhile, the sliding column II slides in the sliding chute III of the disc, so that the linkage of the disc and the combined movement of the closing blade adjust the sectional area of the
shunting channel, a self-adaptive variable cross-section fractal flow path is formed, the fluid distribution and
heat transfer efficiency are optimized, and the fluid resistance is reduced.
