PM induction heater for fluid

摘要

An auxiliary heater is provided for heating a fluid flowing through a pipe. The heater includes a conductor mounted in proximity to the pipe. A magnet is opposed to the conductor with a small gap therebetween. Relative rotation is generated between the conductor and the magnet. The rotation causes the conductor to be heater by slip heat generation. The heated conductor, in turn, heats the fluid in the pipe.
