ABSTRACT:
An electronic frequency converter is used with a high frequency immersion vibrator in order to compact concrete. The frequency converter comprises a cooling circuit containing a cooling medium; a first heat exchanger which is integrated into said cooling circuit and is used to transmit heat generated in the housing of the frequency converter to the cooling medium; and a second heat exchanger which is integrated into the cooling circuit and is used to outwardly transmit heat absorbed by the cooling medium. The second heat exchanger is received in a vibrator housing of the high frequency immersion vibrator. If the vibrator housing is immersed in concrete, the heat produced in the converter housing can be conducted away to the concrete.
