Heat exchange device for LNG (Liquefied Natural Gas) power ship

The utility model belongs to the technical field of integrated heat exchangers, and particularly relates to a heat exchange device for an LNG (liquefied natural gas) power ship, which comprises a shell barrel, one end of the shell barrel is fixedly connected with a barrel flange, the surface of the barrel flange is fixedly connected with a heat flow inlet pipe, one end of the heat flow inlet pipe penetrates through and extends to the inner wall of the shell barrel, and the other end of the heat flow inlet pipe is fixedly connected with a heat exchanger. The other end of the shell cylinder is fixedly connected with a cylinder sealing plate, and the surface of the cylinder sealing plate is fixedly connected with a hot flow outlet pipe. According to the heat exchange device for the LNG power ship, by arranging the heat exchange pressurization mechanism, when the heat exchange device is used, the vaporization function and the self-pressurization function are combined, space use is reduced, the manufacturing cost
