Evaporative condenser is a heat exchange device that saves energy and water by combining the condenser and cooling tower into one unit. It has the advantages of high efficiency, energy saving, and a compact structure. The evaporative cooling technology mainly uses the evaporation of water to absorb latent heat and condense the working fluid inside the tube. The sprayed water is sprayed out through the nozzle pipe by the circulating water pump, forming a liquid film on the surface of the heat exchanger plates. At the same time, the working fluid inside the tube transfers heat to the outer liquid film through the tube wall, and the liquid film exchanges heat and mass with the outside air, transferring heat to the outside air flow.
