By setting the heat exchange plate, the heat exchange area between the inside and outside of the cooling jacket can be increased, thereby further improving the cooling effect inside the inner tower.

[0011] Specifically, sockets for inserting the heat exchange plates are opened at equal intervals on the outer circumference of the cooling sleeve, and one end of the heat exchange plate is inserted into the cooling sleeve through the socket and is welded to the cooling sleeve.
