PURPOSE: A cross flow type cooling tower is provided to reduce noise through an opening by absorbing the noise with a sound absorbing material. CONSTITUTION: A cross flow type cooling tower comprises an air chamber(10), a blower fan(30), a cylinder(40), and a sound absorbing system(50). Whole upper surface(11) of the air chamber is flat. The blower fan is installed inside the air chamber. A top end of the cylinder is combined with a top opening(12) of the air chamber. A lower end of the cylinder is extended inside the air chamber and mounted at an outer periphery of the blower fan. The sound absorbing system is mounted on the upper surface of the air chamber in order to reduce the noise discharged through the opening. |
