PROBLEM TO BE SOLVED: To provide a coolant freezing prevention method for a solidification type transmitter cooling system using a coolant possible to be freezed like water without using the antifreeze as a coolant in the water-cooled solidification type transmitter system. SOLUTION: The cooling water is fed to a solidification transmitter 3 by a pump 2, and cools a power amplifier 4 as a heat generating source to absorb the heat. The cooling water which absorbed the heat of the power amplifier 4 and of which temperature rises is fed to a discharge heat recovery board 5. The discharge heat recovery board 5 separately provided from the solidification transmitter cooling system and a cooling water circulation route is thermally connected (to transfer the thermal energy) to the both, and the operation-side cooling water, of which temperature rises, conducts the heat through the discharge heat recovery board 5, and raises temperature of the cooling water, of which temperature is low, of a waiting side to prevent freeze thereof. The operation-side cooling water restricted in temperature rise is fed to a heat exchanger 6, and further cooled by a fan 7 provided inside the heat exchanger, and returned to a water tank 1.
