Background

An apparatus for condensing a high-temperature and high-pressure gaseous refrigerant using water as a cooling medium is called a water-cooled condenser. Since the temperature of water in nature is generally low, the condensation temperature of the water-cooled condenser is low, which is beneficial to the refrigerating capacity of the compressor and the economical efficiency of operation. Such condensers are mostly used in refrigeration systems. The cooling water used in the water-cooled condenser can flow through the condenser once or can be recycled. When circulating water is used, a cooling water tower or a cooling water pool is required to be built, so that water leaving the condenser is cooled again for reuse.

However, the existing water cooler has low heat exchange efficiency and is easy to cause waste of water resources, most of cooling water contains calcium ions, magnesium ions and acid carbonate, when the cooling water flows through the metal surface, the carbonate is generated, and a pipe can be blocked when scaling is serious, so that the heat exchange effect is lost.
