Principle of evaporator

The working principle of evaporative cooling is that the heat transfer part of the equipment is the heat exchange tube group. Gas enters from the upper part of the heat exchange tube group, is distributed to each exhaust pipe through the header, and flows out from the lower pipe after completing heat exchange. The cooling water is pumped by a circulating water pump to the water distributor at the upper part of the heat exchange tube group. The water distributor is equipped with high-efficiency anti clogging nozzles to evenly distribute the water to each group of pipes; The water flows down in a film like manner on the outer surface of the pipe, and finally falls into the water tank through the filling layer on the upper part of the tank for recycling. When water flows through the cooler tube group, it relies on the evaporation of water and utilizes the latent heat of evaporation of water to cool the medium inside the tube. At the same time, fresh air is drawn in from the ventilation windows around the lower side of the cooler by the axial flow induced draft fan, which promptly carries away the water vapor and creates conditions for continuous evaporation of the water film
