The invention discloses liquid metal cooling and directional condensing equipment with a tin boiler stirrer, which comprises a mould heating and insulating furnace, a ceramic mould, a chilling tray, a drawing bracket, a container, a floating insulation baffle, a first stirrer, a second stirrer and a stirrer drive mechanism, wherein an upper heating area and a lower heating area are reserved in the mould heating and insulating furnace, the ceramic mould is arranged in the mould heating and insulating furnace, and the chilling tray is connected with the ceramic mould and driven by the drawing bracket to move up and down; the container is arranged below the mould heating and insulating furnace and filled with liquid metal tin, and the floating insulation baffle is arranged on the liquid surface of the liquid metal tin; and the first and second stirrers capable of rising and descending are symmetrically arranged in the container. The liquid metal cooling and directional condensing equipment with the tin boiler stirrer solves the problem of overflowing of the liquid metal tin and prevents the liquid surface of the liquid metal tin from rising and contacting the heating furnace; and dueto vertical movement of the stirrers, the heat exchange of the liquid metal tin is speeded up, so that the temperature of the liquid metal tin is uniform.
