Features of Cooling Towers Counterflow tower 1. Water is filled in the tower, the water is from top to bottom, the air is from bottom to top, and the two flow in opposite directions. A cooling tower.How to Leak Detection of Vacuum Furnace 2. The countercurrent cooling tower has good thermal performance and is divided into three cooling sections: ①The space between the water distributor and the top of the filler, the water temperature in this section is relatively high, so the heat can still be transferred to the air. ② Filling water and air heat exchange section. ③ Filling to the water spraying section of the sump space, the water is cooled in this section, which is called "tail effect". In northern my country, the water temperature can drop by 1-2°C. To sum up, the counter-current tower is about 20% smaller than the cross-flow tower under the same conditions, and the heat exchange process of the counter-current tower is more reasonable and efficient.304 stainless steel cold rolling and vacuum annealing process 3. The water distribution system is not easy to block, the water filling is kept clean and not easy to age, the moisture backflow is small, and the anti-freezing and deicing measures are easier. Multiple units can be combined in design. In winter, the required water temperature and water volume can be combined with a single unit or all fans can be turned off. 4. The construction, installation and maintenance are easy and the cost is low. It is commonly used in air conditioners and industrial large and medium-sized cooling circulating water.How to control distortion in vacuum heat treatment of sheet parts?
