<p><P>PROBLEM TO BE SOLVED: To provide an ice making machine comprising a cooling unit of high heat exchanging efficiency without damaging an evaporation tube wound on an outer periphery of a cooling cylinder. <P>SOLUTION: This ice making machine comprises the cooling unit having the evaporation tube 3 spirally wound on the outer periphery of the cylindrical cooling cylinder 2 and allowing a refrigerant to be circulated and supplied therein, and the evaporation tube 3 is attached to the cooling cylinder 2 through a soft non-metallic heat conductive material 20 having rubber elasticity. As the evaporation tube 3 and the cooling cylinder 2 are not firmly joined by applying this constitution, large stress is not generated on the evaporation tube 3, and the generating tube is not damaged, even when compression force by ice inside of the cooling cylinder and heat distortion by the refrigerant inside of the generating tube are acted thereon. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
