Refrigerator liner and heat exchange structure thereof

The invention belongs to the technical field of refrigerators, and particularly relates to a refrigerator liner which comprises side walls of the liner formed by bending plates, wherein a square columnar containing cavity is defined by the side walls of the liner, the joint of the side walls of the liner is turned outwards to form a side turnup, the side turnup divides a side wall of the containing cavity into two straight walls, and a notch for a heat exchange pipe to pass through is formed in the side turnup; a side evaporator attached to the periphery of the side wall of the liner comprises straight wall sections which are formed by uniformly winding the heat exchange pipe on the straight wall and are integrally in a plate shape, and the two straight wall sections located on the two sides of the side turnup are in communication through a straight pipe penetrating through the notch. The side walls of the refrigerator liner is formed by integrally folding the plate, and a connecting turnup is arranged at the
