Analyze the main factors affecting the heat transfer effectiveness of the closed cooling tower

        The purpose of using a closed cooling tower is to meet a specific cooling effect, which mainly depends on the heat sink, fan air volume, equipment water consumption, and good ventilation conditions. The installation location also has some influence.
        1. Heat sink: It is the key component of the equipment. Small towers generally use PVC sheet hot pressing or heat absorption, and large towers will use wood. The main purpose is to make the contact surface of air and water without affecting the wind resistance, the bigger the better The two parameters that affect the effectiveness of heat transfer by the heat sink are mainly the shape and height of the heat sink. During the installation of the water tower, try not to damage the heat sink to avoid poor water flow on the heat sink.
        2. Air volume of closed cooling tower: It mainly accelerates the air flow in the tower, accelerates the heat exchange between air and water, and takes away heat. The air volume of the equipment is mainly affected by the shape of the blade, that is, the width and length of the blade and its own deflection angle, the speed of the blade, the installation angle, the speed and the motor and transmission ratio. In addition, in the case of a specific air volume, the same type of tower, a small amount of cooling water is better than a large amount of water.
