Introduction to the principle of SHENNAI cross flow closed cooling tower
The heat source circulating water is pushed to the coil of the cooling tower through the system circulating water pump. At this time, the spray water pump starts to pu mp the natural cooling water stored in the lower water tank into the spray water tank at the top of the cooling tower. The reasonable and uniform through holes are arranged at the bottom of the spray water tank to fully distribute the spray water on the coil of each layer and on the PVC filler in the middle of each layer of coil, Complete the first heat exchange to take away the heat of the heat source circulating water.
In this process, the mechanical axial flow fan at the top of the cooling tower starts to pump the external dry and cold air into the cooling tower to make the dry and cold air indirectly contact with the coil surface of the internal hot water, and complete the second heat exchange to take away the heat of the heat source circulating water, Both heat exchanges have fans to discharge the humid and hot air in the tower after heat exchange fro m the air duct opening, and finally the cooled heat source circulating water flows out of the tower body, and then the system circulating water pump is sent to the heat source (cooled equipment), so as to complete the cooling back and forth and ensure the stability of the cooled equipment.
During the cooling process, the heat source circulating water flows from the inner side of the tower to the outer side of the tower. At this time, the dry and cold air flows from the outer side of the tower to the inner side of the tower. In this way, the heat source circulating water carries out transverse heat exchange with the dry and cold air at the horizontal level. The heat source circulating water always circulates in the coil of the cooling tower without direct contact with the external air, Therefore, the cooling equipment is a cross flow closed cooling tower.
