Cooling system of thermal power stations.

Cooling system power stations consisting of a closed liquid circuit is cooled in a dry cooler (10), by whose exterior is driven atmospheric air, also having in the closed with a large deposit circuit or aljibe (25) of said liquid. The coolant tank or cistern (25) can be sent to be cooled in the dry cooler (10) when its temperature is higher than the outside air, and the thermal power plant is not operating; or can send the liquid to the cold (6) of the power cycle of the power plant, when it is running and the temperature of the liquid tank (25) is lower than the temperature that can reach the liquid cooling through of dry cooler (10) as the temperature of atmospheric air.
