2The transverse flow tower body is not suitable for finned tubes because the spray water is easily affected by the transverse wind, causing the profile tidal range to change direction on the outer local finned tubes. In a short period of time, dust and scale will form between the fins, causing a double decrease in heat transfer efficiency. However, for the counter flow tower body, the finned tubes are less likely to form bridging or gambling under the flushing of the spray water.SYG [Official Website] - Hebei Huasheng Energy saving Equipment Co., Ltd

Closed cooling tower - difference from open cooling tower 1. The cooling principle of open cooling tower is to spray the circulating water on the glass fiber filler in the form of spray, to achieve heat exchange through the contact between water and air, and then a fan drives the air circulation in the tower to bring out the hot air after heat exchange with water, so as to achieve cooling.
This cooling method requires less initial investment, but has higher operating costs (water and electricity consumption).The difference between open cooling tower and closed cooling tower is quenching liquid. Closed cooling tower, also known as closed cooling tower, is abbreviated as closed tower. Closed cooling tower originated from evaporative cooler, but in fact, it is a heat exchanger that combines the performance of water-cooled cooler and conventional cooling tower. It is also a heat exchanger between water cooler and air cooler, so some manufacturers call it "evaporative air cooler". There are many forms of cooling equipment nowadays, and their common feature is spraying water outside the partition heat exchanger and forced ventilation. Heat is transferred from the cooled fluid inside the partition heat exchanger to the spraying water outside the wall through the wall surface, and then transferred to the air through forced convection between the spraying water and air. The heat transfer of the spraying water to the air is mainly composed of the latent heat of evaporation of the spraying water and the sensible heat exchange between the spraying water and the air. Due to the closed circulation flow of the cooled fluid between the inter wall heat exchanger and the external process equipment, it is called a "closed tower" to distinguish it from general cooling towers where the cooled fluid directly contacts with air. Correspondingly, general cooling towers are called "open towers". Closed cooling tower - Summary: The corrosion, scaling, and mud sticking of heat exchange equipment and system pipelines in open cooling towers (such as circular fiberglass cooling towers) are the three major drawbacks that cause severe corrosion of system pipelines. Calcium, magnesium ions, and calcium carbonate precipitation and scaling are the main reasons, which not only reduce thermal efficiency (a 1mm thick scale layer causes approximately 8% energy loss), but also easily lead to frequent burning of thyristors, interfering with normal assembly line production. In addition, the circulating water of an open cooling tower absorbs a large amount of dust, sediment, flying insects, bacterial and algal spores when in contact with the air, posing a health threat to the working population near the tower through the large amount of sprayed water mist (such as Legionella).
On the basis of replacing direct current water systems, in order to further improve the cooling safety, energy saving, and environmental friendliness of cooling towers, the heat treatment industry has increasingly begun to adopt closed cooling towers in the past decade. 1. Compared with traditional open cooling towers, closed cooling towers achieve fully enclosed internal circulation of cooling water (purified water), greatly avoiding water waste and water pollution, and achieving cost savings in water and electricity. The threat of corrosion and scaling to user equipment has been basically eliminated, especially suitable for enterprises and regions with strict requirements for industrial water quality and quantity;
2. The closed cooling tower body carries a self supplied water system, and its installation and easy reinstallation no longer rely on external water tanks. However, it is very convenient and only includes simple disassembly, installation, and circuit connection of the cooling pipeline.
3. Automated electrical control enables closed cooling towers to adjust air volume and spray rate according to changes in ambient temperature, maximizing efficiency and energy savings in the cooling process. At the same time, the electrical control facilities of the cooling tower can be installed at various locations in the factory according to customer requirements to implement remote control functions and achieve automatic synchronous start-up with user equipment.
4. The manual and automatic setting of key operating parameters such as cooling water level and inlet/outlet temperature with sound and light alarms eliminates frequent manual monitoring, ensuring a smooth cooling process and precise cooling effect.SYG [Official Website] - Hebei Huasheng Energy saving Equipment Co., Ltd
