  • Patent number: 10904472
    Abstract: According to an embodiment, system includes transmitter, pump, controller, tank and thermal storage. Pump circulates water through the transmitter. Controller drives the pump, circulates the water while the transmitter is operating, and stops the circulation of the water at a time of a stop of the transmitter. Tank stores the water circulated through the transmitter, and supplies the water to the pump. Thermal storage is provided on a surface of the tank, and stores waste heat of the exothermic part of the transmitter, which was taken in the water via the tank. Thermal storage changes in phase if a temperature of the water in the tank lowers to a predetermined temperature or below, and heats the water by latent heat which occurs.
