Being the vibrator inside the high frequency which the vibrator null concrete inside the high frequency which possesses

摘要

As for this invention, as for this, the heat which occurs the cooling circulating road which includes coolant the transmitter casing (4) and the frequency changer the 1st heat exchanger which in (2) is transmitted to coolant here with the vibrator inside high frequency the electronic type frequency changer which is used for the compaction of the concrete in regard to (1), is installed in the cooling circulating road (4) the 2nd heat exchanger which the heat which was absorbed in (3) and coolant is transmitted outside, is installed in the cooling circulating road (4) (11) with it possesses. The 2nd heat exchanger (11), the vibrator casing of the vibrator inside high frequency it is accommodated in (6). When the vibrator casing (6) is dampened the concrete (12), the heat which occurs with the transmitter casing (2) is discharged the concrete (12).
