The biggest difference between a closed cooling tower and an open cooling tower is that the closed cooling tower exchanges heat between the cooled medium and the cooling water and air outside the pipe through the coil, forming a closed circulation system, avoiding the contact between the cooled medium and the air. The pollution caused by the waste of cooling medium, equipment blockage and other failures that affect normal use. This equipment is suitable for harsh environments such as drought, water shortage, and frequent sandstorms.
It can be used in industrial manufacturing fields such as central air-conditioning, instrumentation, metallurgical intermediate frequency electric furnaces and converters, power plant generator sets, steam turbine units, nuclear power plants, substations, chemicals, pharmaceuticals, welding, etc., cooling oil for rolling aluminum and copper foil, and hydraulic pressure for large hydraulic machinery Oil.
The scope of application of closed cooling tower:
1. Induction heating and metal melting equipment, such as high and intermediate frequency quenching equipment, intermediate frequency power supply and cooling of electric furnaces, induction diathermic furnaces and holding furnaces.
2. Cooling of circulating water in various reactors and condensers in the chemical industry.
3. Cooling of large motors, diesel engines, rectifier equipment, electric welding equipment, hydraulic stations, continuous casting equipment.
4. Cooling of large molds, such as metal die-casting molds and injection molds.
5. Cooling of industrial solutions, such as quenching solution and electroplating solution.
Advantages of closed cooling tower:
1. The cooling medium is fully enclosed in circulation, which can prevent debris from entering the cooling pipeline system and prevent the loss of cooling medium from evaporation.
2. Using soft water as the cooling medium, no scaling, no clogging of pipes, and fewer failures.
3. Adopt air cooling and water spray evaporation and heat absorption dual cooling method, high cooling efficiency.
4. The device is small in size, takes up a small space, is convenient to move and place, and does not need to build a pool.
5. With automatic intelligent control, the cooling method can be automatically changed according to the working conditions, and the operation is simple and reliable.
6. It has a wide range of uses. It can directly cool the quenching liquid, oil, alcohol and other non-corrosive media on the heat exchanger. The medium is not lost and the composition is stable.
In order to adapt to different cooling media, our company has developed heat exchange coils of different materials, such as carbon steel pipes, copper pipes, stainless steel pipes, aluminum pipes, etc. The structure includes elliptical, threaded and node-shaped tubes, which are used as cooling tubes for fully enclosed cooling. There are two types of cooler structures: coil type and tube box type.
