Including a base, the top of the base is fixedly connected with a supporting column. The top of the supporting column is fixedly connectedwith a supporting plate. A cooling water tank is fixedly connected to the top of the supporting plate, a steam inlet is fixedly connected to the top of the cooling water tank, the steam inlet penetrates through the cooling water tank and extends into the cooling water tank, a spiral pipe is fixedly connected to the bottom of the steam inlet, and the bottom of the spiral pipe penetrates through thecooling water tank and the supporting plate and extends to the bottom of the supporting plate. The utility model discloses a cooling device based on steam. The spiral pipe is immersed in the coolingliquid, so that heat exchange between steam and the cooling liquid is more sufficient, the stirring blades stir the cooling liquid, the temperature of the cooling liquid is more uniform, the cooling efficiency is improved, heat is dissipated into air in the cooling liquid circulation process, the low temperature is kept, and the device can continuously cool the steam.
