Referring to fig. 2, the top mouth of the outlet pipe 15 is higher than the bottom mouth of the inlet pipe 14, so that a constant water level 19 flush with the top mouth of the outlet pipe 15 is formed in the cooling cavity 18. Preferably, the area of the outlet pipe 15 is 1.5 times or more the area of the inlet pipe 14. The bottom of the steel sleeve shell 2 is fixed with the base 7.
