Method for manufacturing auger-type ice maker and the manufactured auger-type ice maker

A method for manufacturing an auger-type ice maker including an ice-making tube, an auger installed coaxially in the ice-making tube, a refrigerant pipe spirally wound around and tightly fixed to an outer surface of the ice-making tube, and a metal core material filling a spiral space formed between the ice-making tube and the refrigerant pipe adjacent to the ice-making tube, comprising:

• heating and feeding the metal core material to the ice-making tube;
• winding the metal core material together with the refrigerant pipe around the ice-making tube;
• and
• heating a welding agent through an internal space of the ice-making tube to perform adhesion between the metal core material and both of the refrigerant pipe and the ice-making tube,
• wherein, in the winding the metal core material together with the refrigerant pipe on the ice-making tube, the heated metal core material is pressurized by pressure of winding the refrigerant pipe around the ice-making tube, to completely fill the spiral space with the heated metal core material, or to form a uniform interval in the spiral space.
