The present invention relates to a heat exchanger of molten salt which is able to efficiently resolve blockage phenomenon of pipe by melting molten salt when the pipe having solidified molten salt is blocked, without damaging performance of the heat exchanger. To this end, the heat exchanger of molten salt comprises: a molten salt flow path forming a moving path of molten salt; a molten salt conversion unit for heat exchanging with the molten salt flow path or heating the molten salt flow path according to contact state with the molten salt flow path while the molten salt flow path is rotatably inserted in a part of a conversion space indicating a circular cross section; and a flow path driving unit for rotating the molten salt flow path as a relative motion with respect to the molten salt conversion unit by corresponding to a solidification state of molten salt, wherein the molten salt flow path is contacting to only one between an operation flow path and a heater unit included in the molten salt conversion unit according to operation of the flow path driving unit. 본 발명은 열교환기 성능에 지장을 주지 않으면서 용융염의 고화가 일어난 배관이 막혔을 때, 용융염을 녹여 효율적으로 배관의 막힘 현상을 해소할 수 있는 용융염 열교환기에 관한 것이다. 이를 위해 용융염 열교환기는 용융염의 이동경로를 형성하는 용융염유로와, 원형 단면을 나타내는 전환공간의 일부에 용융염유로가 회전 가능하게 삽입된 상태에서 용융염유로의 접촉에 따라 용융염유로와 열교환되거나 용융염유로를 가열하는 용융염전환유닛 및 용융염의 고화 상태에 대응하여 용융염전환유닛에 대한 상대 운동으로 용융염유로를 회전시키는 유로구동유닛을 포함하고, 용융염유로는 유로구동유닛의 동작에 따라 상기 용융염전환유닛에 포함되는 작동유로와 히터유닛 중 어느 하나에만 접촉된다.
