Description

The present invention relates to a module and a water tower, and in particular to a condensation module and a cooling water tower.

The water loss of conventional cooling towers includes splash loss (drift), bleed-off loss (bleed-off) and evaporation loss (evaporation), wherein evaporation loss is the main water loss. During the water cooling process in the cooling water tower, a part of the water is evaporated to form water vapor to take away the latent heat of vaporization, thereby reducing the water temperature in the cooling water tower.

In other embodiments, the temperature of the water-cooling liquid may be 8°C to 12°C or other appropriate temperature ranges. After the water-cooling liquid flows into the condensing element 123 through an inlet pipe P of the water-cooling pipeline 126 and exchanges heat with water vapor, the water-cooling liquid leaves the condensing element 123 through an outlet pipe (not shown) of the water-cooling pipeline 126 .

The fan 124 generates a guiding airflow 302 between the connecting portion 122 of the air guiding structure 121 and the opening OP, so that the water vapor flows along with the guiding airflow 302 and passes through the condensing element 123 . The pilot airflow 302 heated by contact with water vapor is discharged from the opening OP.

As shown in FIG. As shown in FIG. 2 , the condensed water 204 flows downward along the gravity direction G into the collector C1 . Then, the condensed water 204 flows from the collector C1 to the return member C2 (shown in FIG. 1 ), and is guided by the return member C2 to return to the water storage area 113 of the main body 110 .

In order to further improve the condensation efficiency of the condensing module 120 , the air guiding structure 121 of this embodiment has an air cooling air inlet 127 , and the air cooling air inlet 127 is disposed between the connecting portion 122 of the air guiding structure 121 and the condensing element 123 . More specifically, the air-cooling air inlet 127 and the fan 124 of this embodiment are arranged on opposite sides of the condensing element 123, so that the external cold air 306 flowing in from the air-cooling air inlet 127 is guided to the condensing element 123 by the fan 124 , and the temperature of the condensing element 123 is lowered by the cold air 306 to improve the condensation efficiency of the condensing element 123 .
