Single crystal furnace cooling mechanism

The utility model relates to the technical field of single crystal furnace auxiliary mechanisms, in particular to a single crystal furnace cooling mechanism. The single crystal furnace cooling mechanism comprises a furnace body, a heat dissipation part and a driving part, the heat dissipation part comprises a bottom plate, a first heat dissipation pipe, a second heat dissipation pipe, a third heat dissipation pipe, a fan, a first water pump, a second water pump, a second heat insulation plate and a water tank, a supporting rod is arranged on the surface of the bottom plate, a top plate is arranged at the top of the supporting rod, the first heat dissipation pipe is wound around the surface of the furnace body, the second heat dissipation pipe penetrates through the water tank, and the water tank is slidably connected with the bottom plate. Cooling water and the furnace body can be separated through the heat dissipation part, the situation that the cooling water and the furnace body are heated together is avoi
