The structure of Water Cooling Tower

The structure of water cooling tower mainly includes two types of open cooling tower and closed cooling tower.
The cooling principle of the open cooling tower is to spray the circulating water to the glass fiber filler in a spray way, through the contact of water and air to achieve the heat transfer effect, and then the air circulation in the tower is driven by the fan, and the hot gas flow after heat exchange with water is brought out, so as to achieve the cooling effect. The investment of this cooling method is relatively small in the first phase, but the operating cost is high, mainly reflected in the water consumption and power consumption.
The cooling principle of the closed cooling tower involves two circulation systems: an inner circulation and an outer circulation. The inner cycle is connected with the object equipment to form a closed circulation system (the circulation medium is soft water), which cools the object equipment and brings the heat in the object equipment out to the cooling unit. The outer circulation cools the cooling tower itself, does not contact with the inner circulating water, and only carries out heat exchange and heat dissipation through the copper tube surface cooler in the cooling tower. In this cooling mode, through automatic control, according to the water temperature to set the operation of the motor, spring and summer in the case of high ambient temperature need two cycles to run at the same time, and autumn and winter in the case of low ambient temperature in most cases only one internal cycle operation.
In addition, the cold water tower is the power plant used to cool water with the structure, its working principle is the use of blowing in the wind and sprinkled down from the water to form convection, the heat source is discharged, part of the water evaporates in the convection, taking away the corresponding evaporation latent heat, thereby reducing the water temperature. Lower the water temperature. Features of the cold water tower include no need for electricity, automatic rotation of the fan, power saving of 100%, water saving of 80%, etc
