[0034] Working principle: When in use, first, the water is cooled by the refrigeration system inside the refrigeration host. Then, the water pump inside the refrigeration host pumps the cooled water from the water pipe inlet and outlet hole 203 into the cold water pipe 205. The cold water pipe 205 on the refrigeration sheet 10 evenly distributed on the inner side of the backpack brings the cold water to the human body surface, absorbs the heat on the human body surface, cools the human body, takes away the human body heat, and makes people achieve a cool and comfortable effect. Then, the water is circulated back to the refrigeration system of the refrigeration host for cooling to complete the heat exchange. The mesh sheet of the refrigeration sheet 10 facilitates the absorption of human body heat by the cold water pipe 205. The mesh structure of the mesh sheet restricts the passage of the cold water pipe 205 inside the refrigeration sheet 10. The cold water pipe 205 can directly contact the human body through the holes in the mesh, enabling the cold water pipe 205 to directly reduce the human body temperature and improving the refrigeration effect. The front left piece 201, the back piece 202, and the front right piece 204 make the refrigeration sheet 10 fit the backpack, and at the same time conform to the human body structure, enabling the refrigeration sheet 10 to cover most of the upper body area of the human body. The water pipe inlet and outlet hole 203 facilitates the entry and exit of the cold water pipe 205 and can be directly connected to the refrigeration host, which can reduce the length of the water pipe, reduce unnecessary heat dissipation, improve the refrigeration efficiency, and hide the pipeline to improve the aesthetics of the backpack. Connecting locking belts 9 are provided at both ends of the backpack. The connecting locking belts 9 are connected to the bottom ends of the front left piece 201 and the front right piece 204, connecting the entire device to form a backpack frame, enabling the user to carry the backpack. Adjusting blocks 13 are provided on the connecting locking belts 9. The connecting locking belts 9 and the adjusting blocks 13 are used to adjust the fastening degree of the backpack, ensuring that the backpack fits the body stably during activities and improving comfort and stability. A connecting belt 108 is provided at the front end of the backpack. A buckle 107 is provided on the connecting belt 108. The connecting belt 108 connects the front left piece 201 and the front right piece 204 through the buckle 107 to form a backpack vest state, enabling the refrigeration sheet 10 to fit the human body more closely. The buckle 107 can also be used to further adjust the fitting degree of the backpack, helping to adjust the fitting degree of the backpack according to the user's body shape and needs, and increasing comfort and stability. Multiple air inlets help ensure the air intake volume. And the air outlet 3 utilizes the characteristic that hot air blows upward above, reducing the inhalation of hot air and further improving the refrigeration effect of the air conditioning host. The mesh auxiliary air inlet 8 is provided to improve the air intake volume while also enhancing the aesthetics of the backpack's appearance.
