Description

Technical Field

[0001] The utility model relates to the technical field of cooling devices, in particular to a central cooling type falling film evaporative cooling tower. Background Art

[0002] Cooling tower is an evaporative heat dissipation device that uses the heat exchange between water and air to produce steam. The steam evaporates and takes away the heat to achieve the principles of evaporative heat dissipation, convection heat transfer and radiation heat transfer to dissipate the waste heat generated in industry or refrigeration and air conditioning to reduce the water temperature to ensure the normal operation of the system. The device is generally barrel-shaped, so it is called a cooling tower. It is widely used in air conditioning circulating water systems and industrial circulating water systems.

[0003] As the filling structure in the cooling tower changes over time, the filling may age or even break due to long-term operation and the influence of the external environment, which will seriously affect the heat dissipation efficiency and cooling effect of the filling, and may deform under the action of high-temperature airflow and water flow for a long time, changing the original structure and heat dissipation performance, resulting in a decrease in cooling effect. At this time, the filling needs to be maintained and replaced. Since the common filling structure is an integrated structure, it is very inconvenient during the disassembly process, and when part of the filling is damaged, it needs to be discarded, and the consumption cost will increase significantly. Therefore, those skilled in the art provide a central cooling falling film evaporative cooling tower to solve the problems raised in the above background technology. Utility Model Content
