A matrix fan comprises a box body and a plurality of centrifugal fan bodies. The front side of the box body is provided with a plurality of windows which are arranged in a matrix mode, and an air inlet is formed in the near-by place of the box body. The multiple centrifugal fan bodies are arranged in the box body and fixed to the multiple windows correspondingly, and the air outlet directions of all the centrifugal fan bodies face the front side of the box body. According to the matrix fan, the multiple small fan bodies are adopted to replace a traditional large fan, the requirement for a large air quantity can be met as well, only the corresponding small fan bodies need to be repaired or replaced when a failure occurs, thus repairing and replacing are convenient, and control over the windspeed and pressure is facilitated.
