The embodiment of the invention provides a refrigerator capable of preventing the upper surface of a middle beam from being frozen, and relates to the technical field of refrigeration equipment. The refrigerator is provided for solving the problem that a lead of a heating device of a middle beam of an existing refrigerator is likely to be affected with cold and damp so as to be aged. The refrigerator capable of preventing the upper surface of the middle beam from being frozen comprises a box body and door bodies used for sealing the box body. The middle beam is arranged at the position of an opening of the box body. The middle beam is of a hollow structure, a heating device is arranged inside the middle beam, and the middle beam is filled with heat insulation materials. The end of the middle beam is in sealed connection with the inner wall of the box body. A lead of the heating device is electrically connected with a control circuit of the refrigerator after penetrating out of the end of the middle beam and the inner wall of the box body. The refrigerator capable of preventing the upper surface of the middle beam from being frozen is used for storing goods at a low temperature.
