The invention relates to the technical field of cold storage of medical drugs, in particular to a multifunctional medical refrigerator. The multifunctional medical refrigerator comprises a box, an airpump arranged at the top of the box, and a plurality of wheels arranged at the bottom of the box. A refrigeration chamber and a cold storage chamber are sequentially arranged in the box. A pluralityof first supporting frames are horizontally arranged in the refrigeration chamber from top to bottom. A condensation pipe is laid in the refrigeration chamber. The air inlet end of the condensation pipe communicates with the output end of the air pump. A fixing rod is tightly welded to the inner wall of the top of the cold storage chamber. A plurality of drug storage racks are arranged at the bottom of the fixing rod. According to the multifunctional medical refrigerator, the air pump and a motor are powered on by an external power supply to achieve air refrigeration in the refrigeration chamber and rotation of refrigeration pipes, and then cold air is evenly output to achieve comprehensive refrigeration of medical drugs; and ultraviolet lamps can be powered on by the external power supplyto sterilize and disinfect the environment in the cold storage chamber, and thus, storage of the medical drugs is further facilitated; and the refrigerator is simple in structure, has various functions and can be popularized.
