Hydrophilic Aluminum Fin Glycol-Water Cooler Closed Loop Cooling Systems Multiple Circuits
Dry cooler vs wet cooling tower:
Dry coolers are heat-transfer devices that use air to remove excess heat. Usually, a dry cooler presents a heat exchanger (usual fin heat exchanger) and fans. The fans are responsible for directing the airflow through the heat exchanger. Here, the fluid (it can be water or another solution) is cooled and circulated back into the system.
For a dry cooler to be efficient, the air temperature needs to be cooler than the water (or any other glycol solution) in the system. This explains why, for example, dry coolers work better in cold climate regions (while wet cooling towers are more efficient in hot and dry climates). Dry coolers are not affected by air humidity, on the contrary to wet cooling towers.
Dry coolers have a limited cooling capacity, compared to wet cooling towers: the first one only brings the water temperature down to the ambient temperature (additional cooling can be achieved in other ways), while the latter can bring the water temperature up to 5 degrees down the ambient temperature.
