What is a open cooling tower:
What we usually call a cooling tower refers to an open cooling tower: in the tower, hot water is sprayed into droplets or water films through a water distribution system. The water flows from top to bottom, and the air flows from bottom to top or horizontally. The evaporation of water and the heat transfer of cold air and hot water take away the heat in the water.
Classification of cooling towers
Cross-flow cooling tower: refers to a cooling tower in which the cooling water passes through the packing from top to bottom, while the air flows through the packing from a horizontal and diagonal direction. The flow direction of the hot water and air is nearly 900 (some manufacturers also call it It is a straight cooling tower).
Counter-flow cooling tower: refers to a cooling tower in which the cooling water passes through the packing from top to bottom, while the air flows through the packing from bottom to top. The flow direction of hot water and air is close to 1800 (some manufacturers call it convection Cooling Tower).
Motor, fan, reducer (usually belt speed reducer), at the top of the cooling tower is a mechanical ventilation cooling tower, and at the bottom of the cooling tower is a mechanical blast cooling tower.
The realization form of cooling tower cooling:
The main aspect (latent heat) is to absorb the heat of water through the evaporation of water to cool the water; the secondary aspect (sensible heat) is to generate heat transfer through the temperature difference between water and air.
