Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a ferrous metal smelting cooling tower. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from the system and discharge it into the atmosphere to lower the water temperature. Water cooling uses the flow of water and air to exchange heat 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 lower the water temperature. This evaporative heat dissipation device uses 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 lower the water temperature to ensure the normal operation of the system. The device is generally barrel-shaped, hence the name cooling tower.
