The invention relates to a forced air-cooled condenser, which is applied to an air-cooled refrigerator. A water spraying device with an electromagnetic water inlet valve is installed on the air inlet side of an ordinary forced air-cooled condenser. The working state of the electromagnetic water inlet valve is synchronous with the fan. When the fan works, the mixture of air and water flows to the condenser to participate in heat exchange. The temperature of the microenvironment medium in the condenser is lowered and the temperature of the condenser is lowered by utilizing the heat absorption principle of water vaporization. The heat exchange efficiency of the condenser is improved by lowering the condensing temperature and pressure. The reduction of condensation pressure means the reduction of compressor power consumption, which is conducive to prolonging compressor life and reducing the probability of refrigeration machine failure. Therefore, the invention effectively ensures the heat transfer efficiency of the condenser, and has the effects of energy saving, prolonging the compressor life and improving the working reliability of the refrigerator. Especially suitable for summer and autumn high temperature extreme weather conditions, reduce the probability of high pressure protection failure of the refrigerator, to ensure the refrigeration effect.
