What is closed cooling tower

Brief introduction of closed cooling tower closed cooling tower, or closed cooling tower, also known as closed cooling tower, referred to as closed tower The closed cooling tower originates from the evaporative cooler, but actually it is a heat exchanger combining the performance of the water-cooled cooler and the conventional cooling tower, and it is also a heat exchanger between the water cooler and the air cooler, so there are also manufacturers called it "evaporative air cooler" This kind of cooling equipment has many forms Its common feature is to spray water and forced ventilation outside the wall heat exchanger Heat is transferred from the cooled fluid inside the wall heat exchanger to the spray water outside the wall through the wall, and then to the air through the forced convection between the spray water and air The heat transfer of the spray water to the air is mainly the latent heat evaporated by the spray water and the heat of the spray water and air Composed of sensible heat exchange Due to the closed circulation flow of the cooled fluid between the wall type heat exchanger and the external process equipment, it is different from the general cooling tower where the cooled fluid directly contacts with the air, so it is called "closed tower", and the general cooling tower is correspondingly called "open tower".
