The open cooling station is the most widely used and the most type of cooling station. According to the different ways in which hot water and air contact, cooling stations include cooling pools and cooling towers.
(1) Cooling pool
Cooling pool is the use of natural or artificial ponds, reservoirs and other structures to cool circulating water. This is the earliest cooling station used. It uses natural evaporation to cool the water that has absorbed heat and then recycle it. It is characterized by slow cooling process, low efficiency, small temperature difference between cold and hot water, and requires a large amount of water storage and floor space. The cooling pool is divided into two types: natural cooling pool and water spray cooling pool.
(2) Cooling tower
The cooling tower is a tower that heats the cooling water heated by heat exchange during the production process. It is directly in contact with the air, and is cooled by evaporation and conduction, or indirectly through the heat exchanger wall and the air. Type cooling structure. The cooling tower is equipped with filler-water spraying device, and the water and air pass through the filler, which increases the contact area, and has the characteristics of small area and good cooling effect
