Abstract：Molten salt energy storage is the main technical direction of large-scale high temperature heat storage,but the problem of freezing blockage will occur during the operation of salt pipeline,which will affect the safety of the system.In this paper,an ultrasonic transducer is installed on the pipeline which is prone to freeze blockage in the molten salt energy storage system.The numerical simulation results show that when the ultrasonic frequency is 30 kHz,the central temperature of the pipeline is increased by 8 K,and the maximum temperature is increased by 22 K,and the heat transfer effect of molten salt is the best.
