[0059] like Figure 2 As shown, the core of the whole device is the thermoelectric cooler 2, which adopts thermoelectric cooling technology. According to the Peltier effect, when the current passes through the interface of two different conductors or semiconductor materials, it absorbs or releases heat, and then uses the fan assembly to cool or heat the object evenly and without dead ends. This product uses the Peltier effect of the thermoelectric cooler 2, and uses the insulation material and the isolation plate 9 to separate the product into two working chambers, and then uses the generated cold air and hot air at the same time through two fan assemblies, thereby greatly improving the energy utilization rate.

[0060] A first heat sink 5 and a first fan 7 are installed on one side of the thermoelectric cooler 2. The heat sink 17 of the first heat sink 5 and the side of the thermoelectric cooler 2 are coated with thermal conductive silicone grease and then bonded together, which has a good heat transfer effect. A second heat sink 6 and a second fan 8 are installed on the other side of the thermoelectric cooler 2. The heat sink 17 of the second heat sink 6 and the side of the thermoelectric cooler 2 are coated with thermal conductive silicone grease and then bonded together, which has a good heat transfer effect. An insulation ring 11 is installed between the outer wall of the thermoelectric cooler 2 and the inner wall of the mounting groove 10. The insulation ring 11 is tightly connected between the inner wall of the mounting groove 10 and the outer wall of the thermoelectric cooler 2 to achieve isolation of the two sides of the thermoelectric cooler 2.

[0061] Positioning holes are provided at the corners of the first radiator 5 and the second radiator 6, and connecting holes are provided at the corners of the first fan 7 and the second fan 8. The positioning holes and the connecting holes are provided correspondingly, and the positioning holes and the connecting holes are connected by connecting screws.

[0062] When the portable air cooling device is working, a hot surface and a cold surface are formed on both sides of the thermoelectric refrigerator 2, and the first radiator 5 and the second radiator 6 respectively perform heat exchange on the two sides of the thermoelectric refrigerator 2. The fan can speed up the heat transfer speed and realize the rapid output of hot air and cold air. Hot air realizes the heating function, and cold air realizes the cooling function. It can be used for take-out food storage to achieve the storage needs of food insulation and refrigeration. When food is carried, it can meet the dual requirements of food cooling and heating. When beverages are carried, they can meet the dual requirements of cold drinks and hot drinks. The thermoelectric refrigerator 2 is small in size, and no additional refrigeration system is required during the cooling and heating process, and there is no risk of refrigerant leakage.
