PROBLEM TO BE SOLVED: To provide a system for re-liquefying evaporating gas of an LNG vessel.SOLUTION: A system for re-liquefying evaporating gas of an LNG vessel comprises: a compressor which compresses evaporating gas; a heat exchanger which cools evaporating gas compressed by the compressor through heat exchange with the evaporating gas as a coolant; and expansion means which expands fluid cooled by the heat exchanger. The heat exchanger has: a core where the heat exchange is performed between high temperature fluid and low temperature fluid; and fluid dispersion means which disperses fluid flowing into the core or the fluid discharged from the core. The core has a plurality of dispersion blocks.SELECTED DRAWING: Figure 10
