The invention discloses a tilting device for a refrigerator evaporator, which comprises a stander, wherein the stander is provided with a left neck seat and a right neck seat which correspond to each other, the left neck seat and the right neck seat are provided with at least two groups of necks which can be blocked into elbows at bending parts at two ends of evaporator tube banks and a propulsion device for propelling the necks to perform rotary motions respectively, and the stander is also provided with a driving device which drives the left neck seat and the right neck seat to move close to each other or move far away from each other. The tilting device can perform tilting processing on the refrigerator evaporator with special requirements according to prescriptions of the technical requirement so that two adjacent tube banks are arranged obliquely from high to low with adjustable distance between a higher part and a lower part so as to satisfy specific demands of refrigerator manufactures.
