The utility model provides a ship dual-fuel engine gas supply system adopting a PCHE low-temperature heat exchanger, the gas supply system comprises an LNG gasification heating unit, an LNG filling station, an LNG storage tank, an LNG filling pump, a water/ethylene glycol heating system and an LNG buffer tank, and the gasification heating unit is the PCHE low-temperature heat exchanger. According to the ship dual-fuel engine gas supply system, the cold medium plates and the hot medium plates are arranged and stacked at intervals to form a channel of the external connecting pipe, and a pressure-bearing shell does not need to be welded outside to surround and connect the channel of the core body, so that the cost is greatly reduced, and the construction period is also greatly shortened; and the cold and hot connecting pipes are arranged on the same side, so that the equipment is more compact and regular when being mounted on the system, and the heat exchange efficiency of the system is remarkably improved.
