Crossflow cooling tower, where water flows vertically down from the top of the tower and air horizontally moves through the spray filling material, with the airflow being perpendicular to the water flow. The crossflow cooling tower employs intake on both sides, powered by high-performance fans at the top, allowing air to pass through the filling material on both sides of the tower to exchange with hot water, and then exhaust the humid air outside. The filling material consists of point-wave sheets with protrusions on both sides, bonded into a whole by the installation head to enhance rigidity. The protrusions on both sides also prevent direct dripping, thereby improving the water film formation capability. Water collection measures are provided at the end of the filling material.
