[0030] In this embodiment, the cooling jacket 2 and the sleeve 3 are both cylindrical, and the diameter of the sleeve 3 is greater than that of the cooling jacket 2. The cylindrical cooling jacket 2 and the sleeve 3 are wrapped around the outer end of the crucible base 1. The cooling water can be contained in the cavities of the cooling jacket 2 and the sleeve 3. When the cooling water flows into the cavities of the cooling jacket 2 and the sleeve 3, the heat of the crucible base 1 on the inside can be taken away to absorb heat.
