The utility model relates to an assembled cross-flow multi-blade fan. The assembled cross-flow multi-blade fan comprises a fan shaft, a left fan impeller and a right fan impeller, the left fan impeller and the right fan impeller are coaxially and fixedly connected to the fan shaft; the left fan impeller and the right fan impeller are each composed of a plurality of blade fixing discs arranged in the axial direction and a plurality of blades detachably inserted and fastened to the blade fixing discs, and the blades are evenly distributed in the circumferential direction and spirally extend in the axial direction. In the direction from left to right, the rotating direction of the blades on the left fan impeller is anticlockwise, the rotating direction of the blades on the right fan impeller is clockwise, and the rotating angles of the blades on the left fan impeller and the right fan impeller are equal, so that the left fan impeller and the right fan impeller jointly form a V-shaped fan blade arrangement struct
