In equipment that needs to maintain a temperature in the range of 70 to 100 degrees Fahrenheit throughout the whole year, an industrial cooling tower can make water as a transmission medium to effectively transfer excess heat from one location to another.
The cooling tower is essentially a large box that can maximize the evaporation of water. To achieve this, the PVC plastic board is a common material used in the cooling tower, which helps water evaporate. This material filled inside the cooling tower is called "cooling tower filler".
The large cooling tower, such as that in nuclear power plants, relies on natural ventilation or airflow in the cooling tower for cooling. However, this method only works for some ultra-large cooling towers. Most cooling towers use electric fan motors to generate airflow through the cooling tower, which is called "induced draft or forced draft" cooling towers.
The flow of air and water are opposite in a counterflow cooling tower while they flow across each other in a cross flow cooling tower. The occupied space and operating weight of a counter flow cooling tower are often smaller than that of a cross flow induced draft cooling tower. However, due to the use of a pressurized spray system, the water pressure drop of a counter flow cooling tower is often higher. And most cross flow cooling towers use gravity water supply distribution plates.
Cooling tower systems have many types of sizes and designs, which are usually used for cooling products and machinery. They have a wide range of applications, including injection molding, tools and die-cutting, food and beverages, chemicals, lasers, machine tools, semiconductors.
