         2 . The tube pattern for a refrigerator evaporator according to  claim 1 , wherein a bending radius at a bending center of the tubes is in the range of 18.0 mm to 22.0 mm. 
     
     
         3 . The tube pattern for a refrigerator evaporator according to  claim 1 , wherein the evaporator is arranged with a single column of the tubes at every evaporator depth of 25 mm. 
     
     
         4 . The tube pattern for a refrigerator evaporator according to  claim 3 , wherein the evaporator has an evaporator depth of 75 mm, and is provided with three columns of the tubes. 
     
     
         5 . The tube pattern for a refrigerator evaporator according to  claim 3 , wherein the evaporator has an evaporator depth of 50 mm, and is provided with two columns of the tubes. 
     
     
         6 . The tube pattern for a refrigerator evaporator according to  claim 3 , wherein the evaporator has an evaporator depth of 100 mm, and is provided with four columns of the tubes. 
     
     
         7 . The tube pattern for a refrigerator evaporator according to  claim 1 , wherein the evaporator is arranged with a single column of the tubes at every evaporator depth of 20 mm. 
     
     
         8 . The tube pattern for a refrigerator evaporator according to  claim 7 , wherein the evaporator has an evaporator depth of 60 mm, and is provided with three columns of tubes.
