The utility model discloses a high-strength composite collecting pipe which comprises a liquid inlet pipe and a liquid outlet pipe which are arranged in parallel at an interval, the side faces of the liquid inlet pipe and the liquid outlet pipe are communicated with two independent collecting pipe sets which are distributed in the axial direction, each collecting pipe set comprises a plurality of collecting pipes which are arranged in parallel, and flat pipes are communicated between the opposite collecting pipes. The collecting pipes are arranged in multiple rows relative to the liquid inlet pipes and the liquid outlet pipes, so that the number of the collecting pipes is increased to a certain extent, and the medium flow and the heat exchange speed are improved; meanwhile, the flat pipes are horizontally arranged in the axial direction of the collecting pipes, the size of equipment is reduced, the number of the flat pipes is guaranteed, meanwhile, the distance between the flat pipes is increased to a certain
