Water-cooled frequency converter

The utility model discloses a water-cooled frequency converter comprising an enclosed housing; a radiator is arranged in the housing; the water-cooled frequency converter also comprises a cooling device including a water cooling tower, a spray pipe group arranged in the water cooling tower, a heat exchange copper pipe arranged in the housing, and a cycle water pump with a water inlet arranged in the lower portion of the water cooling tower; an inlet of the heat exchange copper pipe is connected with an outlet of the cycle water pump; an outlet of a heat exchange water pump is connected with the spray pipe group; the heat exchange copper pipe is attached to fins of the radiator. The housing of the frequency converter is the enclosed housing; a water-cooled mode can bring the heat of electric devices in the frequency converter; the cycle water is good in cooling effect and less affected by outer temperature environment, thus ensuring stable work of the radiator; no airflow can bring dusts into the frequency converter housing in a cooling process, thus preventing dusts in the air from entering the housing, thus causing damages to the electric devices; the water-cooled frequency converter can reduce frequency converter fault rate, and prolongs life of the frequency converter.
