Description

Technical Field

[0001] The utility model belongs to the technical field of cooling towers, in particular to a mechanical ventilation cooling tower. Background Art

[0002] Mechanical draft cooling tower is a cooling tower that is ventilated by wind. The cooling tower consists of a fan, a tower body, fillers, a water collector, shutters, etc. Mechanical draft cooling towers can be divided into cross-flow cooling towers and counter-flow cooling towers. Mechanical draft cooling towers do not have tall wind turbines. The air flow in the tower is not generated by the air density difference inside and outside the tower, but by the fan. Mechanical draft cooling towers have the characteristics of good cooling effect and stable operation. Mechanical draft cooling towers can be divided into blast type and exhaust type cooling towers, which use exhaust fans or blowers to force air flow. It has high cooling efficiency, stability, small footprint, low infrastructure investment, but high operating costs. Among them, the exhaust type makes the tower in a negative positive pressure state, which is conducive to water evaporation, while the blast type is the opposite. The blast type cooling tower is mainly used in small cooling towers or cooling towers where water is corrosive to the fan. Mechanical draft cooling towers are mostly used in central air-conditioning systems of urban commercial buildings.

[0003] For example, a mechanical ventilation cooling tower with publication number CN218455398U drives the blades to rotate through a fan, thereby discharging the high-temperature steam in the cooling tower. A cooling tower with this structure consumes a lot of electricity. In order to reduce the electricity consumption, a mechanical ventilation cooling tower is proposed. Utility Model Content
