The heat is transmitted from the fluid through the wall of the heat exchanger plates to the cooling water from the tower, which is being continuously circulated through the heat exchanger.The fan at the top of the tower draws air through the tower in counter-flow to the water, thereby evaporating a small amount of the re-circulating secondary circuit water. The evaporative process causes cooling of the remaining water and the heat is released to atmosphere,. The remaining water is re-circulated by the spray water pump from the basin to the spray nozzles. A small quantity of heat is transmitted by sensible heat transfer to the external air, in a similar manner to an air cooler.
