The invention discloses a refrigerator car carriage. The refrigerator car carriage comprises a top plate, a front surrounding plate and side plates. Section assemblies are arranged at the portion where the top plate is connected with the front surrounding plate, the portions where the top plate is connected with the side plates and the portions where the side plates are connected with the front surrounding plate respectively to serve as connecting pieces for the plates. Each section assembly comprises a first section piece, a second section piece and a hard plastic strip used for connecting the first section piece with the second section piece. Each first section piece comprises a connecting plate and a bent plate, wherein the bent plate and the connecting plate are integrally formed. Each second section piece comprises an L-shaped installation plate and a bent part arranged in the middle of the inner side of the installation plate. Two installation grooves are formed in the outer side face of each bent plate, wherein the two installation grooves and the corresponding bent plate are integrally formed. Two clamping grooves corresponding to the corresponding installation grooves are formed in the bent part of each second section piece. One end of each hard plastic strip is arranged in the corresponding installation groove, and the other end of each hard plastic strip is arranged in the corresponding clamping groove. The refrigerator car carriage is convenient to install and good in cold storage effect, and the section assemblies of the refrigerator car carriage are simple in structure and low in manufacturing cost.
