A closed cooling tower is actually a tubular heat exchanger placed inside the tower, which can exchange heat between the temporary water inside and outside the pipe and the circulation inside the pipe through some circulating air, thereby achieving a certain cooling effect. Due to the internal circulation of the circulating water type pipeline, it not only ensures that the water quality is not polluted, but also prevents blockage, thereby achieving cooling and cooling. In some fields such as air compressors and industrial water cooling caused by aluminum profile processing, it is most commonly used, and air conditioning cooling and some refrigeration industries are also abundant. However, closed cooling towers are also one of the three most common tower types, each with different characteristics.

1. Long usage time

However, due to its short service life, its usage is relatively small. Copper pipes and some stainless steel pipes are more common. Due to the significant differences in the materials of these three types of coils, many enterprises choose closed cooling towers, and air will also be left outside during the process of some process fluids flowing through the pipeline. Of course, these two cooling towers are some of the cooling towers that come into contact with each other, which is actually a deformation or development of traditional cooling towers. When the circulating water pump in the pool draws water, it can be sent to the soldiers for spiritual spraying. If the closed cooling tower is operated under particularly closed conditions in winter, it does not need to be operated. During shutdown, it can discharge some edge water or internal circulation operations. In the recommended process of circulating water internally, it is generally necessary to use some high pressure compression before emptying the air.

< 2. Antifreeze treatment

Therefore, in the process of heat exchangers, ventilation is generally not used for relevant antifreeze treatment. Without corresponding contact with some public welfare fluids such as hot water or refrigerants and outdoor air, they can become a closed cooling tower. By spraying water, the heat and mass transfer effect can also be enhanced. Of course, this type of cooling tower is suitable for cooling systems with high requirements for circulating water quality, and is widely used in some electric power, chemical and food industries, with certain application prospects. On the other hand, compared to some warm ventilation systems, this type of cold cooling tower utilizes the evaporation potential of water inside the pipe, but it can also significantly enhance and have significant advantages. Its advantages can improve production efficiency.
