[0010] Preferably, the first box body is provided with a second recessed groove on both sides, and a handle is provided inside the second recessed groove. The handle is designed to facilitate the user to exert force when carrying the entire transport box body.
[0011] Preferably, the surface of the first box cover is provided with several stacking slots, the bottom of the first box body is provided with several stacking protrusions, and the surface of the first box body is also provided with a temperature recorder capable of detecting the internal temperature of the first box body.
[0012] Preferably, the dry ice box is made of polyethylene, because polyethylene has excellent low-temperature resistance, good chemical stability, and can withstand the corrosion of most acids and alkalis.
[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. During the frozen transport process, the circulating fan can stir the air inside the first box. When the fan blades rotate, the air circulates, which can improve the refrigeration efficiency of the cold chain box, help maintain the uniformity of the temperature inside the box, avoid local overcooling, and bring convenience to the use; 2.

[0019] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:
[0020] like Figures 1 to 4 As shown, an aviation cold chain transport box structure includes a transport box body 1. The transport box body 1 includes a first box body 12, a first box cover 13, and a sealing ring 14. The surface of the first box body 12 is provided with a rectangular limiting groove 121, and the sealing ring 14 is provided inside the rectangular limiting groove 121. The first box cover 13 is detachably connected to the surface of the first box body 12 by a latch 4. With this arrangement, whenever the first box cover 13 and the first box body 12 are locked, the sealing ring 14 will be squeezed. The sealing ring 14 is made of relatively thick EPDM rubber. The function of the sealing ring 14 after being squeezed is mainly to keep warm and prevent cold air leakage and external heat from entering, thus achieving a preliminary insulation effect.
[0021] In this embodiment, the interior of the transport box body 1 is provided with a first support plate 11. The gap between adjacent first support plates 11 is used to place transported items. The surface of the first support plate 11 is provided with a first cold source 2 for freezing. The first cold source 2 is a dry ice box 21, which contains dry ice. Several dry ice boxes 21 are stacked on the surface of the first support plate 11. The side wall of the first cold source 2 is provided with a guiding element 3 that can guide cold air to each corner of the transport box body. The guiding element 3 is a circulating fan 31, which can blow cold air to each corner of the box body. Moreover, the dry ice box 21 is made of polyethylene, which is a thermoplastic resin obtained by polymerizing ethylene. Polyethylene is odorless, non-toxic, has a waxy feel, excellent low-temperature resistance (minimum operating temperature can reach -100℃ to 70℃), good chemical stability, and can resist the corrosion of most acids and alkalis (but not oxidizing acids). It is insoluble in common solvents at room temperature, has low water absorption, and excellent electrical insulation. Furthermore, the dry ice box 21 has excellent thermal insulation properties, effectively isolating the dry ice from the influence of external temperatures and keeping it solid at a very low temperature (approximately -78.5 degrees Celsius). This ensures the refrigeration needs of temperature-sensitive goods. Ice is also an excellent preservative material used for freezing and maintaining the freshness of food, medicine, and other perishable items. Using dry ice boxes can extend the preservation time and ensure product quality and safety. As for the circulating fan 31, it can agitate the air inside the first compartment 12. The rotating blades of the circulating fan 31 circulate the air, which can improve the refrigeration efficiency of the cold chain box. This is very important for maintaining the low temperature of the dry ice and extending its service life. In the cold chain box, this helps to maintain the uniformity of the internal temperature and avoid localized overcooling.
[0022] In this embodiment, the first box body 12 has first recessed grooves 122 on both sides. The first recessed grooves 122 contain a pressure relief valve 5 and a drain valve 6. The pressure relief valve 5 can release gas from inside the box body 13 under certain conditions, keeping the transport box within a stable and safe pressure range. The drain valve 6 can periodically drain condensate as needed. Furthermore, the bottom of the box body 13 is designed with a slight inclination towards the drain valve 6 to ensure complete drainage of condensate from the transport box. The first box body 12 also has second recessed grooves 123 on both sides. The second recessed grooves 123 contain handles 7. The handles 7 are designed to facilitate the user's effort when carrying the entire transport box body 1. To facilitate stacking of multiple transport box bodies 1, the surface of the first box cover 13 has several stacking slots 131. The bottom of the first box body 12 has several stacking protrusions 124. The surface of the first box body 12 also has a temperature recorder capable of detecting the internal temperature of the first box body 12. This design facilitates monitoring the internal temperature of the first box body 12.
[0023] Working principle and usage of this utility model:
[0024] First, unlock the latch 4 to allow the first lid 13 to separate from the surface of the first box body 12. Then, place the transported items into the gap between the adjacent first support plates 11. Next, place the dry ice box 21 on the surface of the first support plate 11, and then lock the first lid 13 again. During this frozen transport process, the dry ice inside the dry ice box 21 can freeze and maintain the freshness of food, medicine and other perishable items. The circulating fan 31 can stir the air inside the first box body 12. When the blades of the circulating fan 31 rotate, the air will circulate, which can improve the refrigeration efficiency of the cold chain box and help maintain the uniformity of the temperature inside the box, avoiding local overcooling. The pressure relief valve 5 can discharge the gas inside the box body 13 under certain conditions, keeping the transport box always within a stable and safe pressure range. The drain valve 6 can discharge condensate as needed.
