Claims

[Claims for Utility Model Registration] The cooling pipe has a structure in which a cooling pipe through which a refrigerant flows is attached to a cooling plate, and the cooling pipe has a plurality of vertical parts extending substantially vertically, and ends of the vertical parts. In the evaporator for a refrigerator, the lateral part of the cooling pipe has a predetermined slope with respect to the horizontal direction; Alternatively, the cooling pipe has a curved shape, and further, a predetermined gap is provided between the cooling pipe and the cooling plate near a portion where the slope of the cooling pipe changes from downward to upward.
