[0063] When the portable air cooling device works, the thermoelectric refrigerator 2 forms a hot surface and a cold surface on two sides respectively, the first radiator 5 and the second radiator 6 respectively exchange heat with the two sides of the thermoelectric refrigerator 2, and the fan can accelerate the heat transfer speed to realize the rapid output of hot air and cold air. The hot air realizes the heating function, and the cold air realizes the refrigeration function. It can be used for food storage of take-out, and realize the storage demand of food heat preservation and cold storage. When carrying food, it can meet the dual requirements of food refrigeration and heating. When carrying beverages, it can meet the dual requirements of cold drinks and hot drinks. The thermoelectric refrigerator 2 is small in size, and does not need an additional refrigeration system in the refrigeration and heating process, and there is no risk of refrigerant leakage.
