Description

A cold storage refrigerated transport box for cold chain applications Technical Field

[0001] This utility model belongs to the technical field of refrigerated transport boxes, specifically relating to a cold storage refrigerated transport box for cold chain applications. Background Technology

[0002] Currently, common cold storage refrigerated transport boxes on the market mainly consist of a box body and a lid. The box body has an internal storage chamber with an open top for easy placement of the object to be transported. One end of the lid is hinged to the box body, and the other end is fixed to the box body via magnetic or snap-fit ​​connections to seal the storage chamber. During use, ice packs are evenly placed inside the storage chamber, the object to be transported is placed inside, and finally the lid is closed and secured. Relying on the cold released by the ice packs and the insulation properties of the box body itself, a refrigerated environment is provided for the object to be transported, providing protection and insulation.

[0003] As can be seen from the above, existing cold storage refrigerated transport boxes have the following defects when in use: Although ice packs are evenly placed in the containment chamber, the ice packs are usually in direct contact with the objects to be transported. This contact method severely hinders the normal circulation of air in the containment chamber, resulting in extremely uneven temperature distribution in the storage chamber. The temperature in the area near the ice packs is too low, while the temperature in the area away from the ice packs is relatively high. For temperature-sensitive items such as food, medicine, or fresh produce, this temperature difference is fatal. Some items may deteriorate faster due to prolonged exposure to high-temperature environments, which not only affects product quality but may also cause serious economic losses and safety hazards. When transporting cultured cells, the low temperature may also cause some cells to die, affecting the quality of cell preparations. Summary of the Invention

[0004] To address the above problems, the purpose of this utility model is to provide a cold storage refrigerated transport box for cold chain applications, thereby solving the problems mentioned in the background art.

[0005] This utility model provides a cold storage refrigerated transport box for cold chain applications, including a box body, the inner wall of which defines an open-top receiving chamber; a cover that cooperates with the box body to seal the open receiving chamber; and an isolation frame placed inside the receiving chamber for evenly distributing ice packs around the object to be transported, thereby achieving uniform temperature distribution within the box. The isolation frame includes a frame for supporting the object to be transported and forms a storage cavity for placing ice packs with the inner wall of the box. Multiple layered panels are provided, distributed around the frame, dividing the storage cavity into multiple partitioned cavities for placing side ice packs, achieving uniform distribution of ice packs.

[0006] Preferably, the layered panels on the side walls of two adjacent frames are arranged in an alternating pattern in the height direction.

[0007] Preferably, the layered plate is detachably connected to the frame.

[0008] Preferably, a tray for placing bottom ice packs is installed between the bottom of the frame and the bottom wall of the box, and water collection trays are fixedly connected to all four sides of the tray.

[0009] Preferably, the wall of the enclosure has a double-layer structure, which includes an outer wall layer and an inner wall layer, and a filling cavity is formed between the outer wall layer and the inner wall layer for filling the insulation layer.

[0010] Preferably, it also includes a temperature sensor installed on the enclosure, and a display screen for displaying the real-time temperature inside the storage room is embedded on the outer wall of the enclosure.

[0011] Preferably, the box is also equipped with an ultraviolet germicidal lamp for sterilizing and disinfecting the storage room.

[0012] The beneficial effects of this utility model are: by setting up an isolation rack inside the containment chamber and evenly distributing ice packs around the object to be transported, a comprehensive and three-dimensional cold energy distribution system is constructed, making the temperature distribution inside the box more uniform and providing a stable and suitable refrigeration environment for the object to be transported.

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0020] This utility model relates to an existing cold storage refrigerated transport box, which mainly includes a box body 1 and a lid 3. The box body 1 has an internal receiving chamber 2 with an open top for easy placement of the object to be transported. One end of the lid 3 is hinged to the box body 1. When the lid 3 is on top of the box body 1, the other end of the lid 3 is connected to the box body 1 by magnetic attraction or snap fasteners to seal the receiving chamber 2. In use, ice packs are evenly placed in the receiving chamber 2, and then the object to be transported is placed in the receiving chamber 2. The lid 3 is then closed onto the box body 1 and fixed in place, providing protection and insulation for the object to be transported. The above is an introduction to the existing cold storage refrigerated transport box.

[0021] As can be seen from the above, existing cold storage refrigerated transport boxes have the following defects when in use. Although ice packs are evenly placed in the storage chamber 2, the ice packs and the objects to be transported are generally in direct contact, resulting in poor air circulation in the storage chamber 2. This leads to uneven temperature distribution in the storage chamber, with lower temperatures near the ice packs and relatively higher temperatures in areas away from the ice packs. This may cause some food, medicine, or fresh produce to spoil due to the higher temperature environment. Based on the above problems, this utility model adopts the following improvement method to solve them.

[0022] As shown in Figures 1-4, a cold storage refrigerated transport box for cold chain applications, based on existing technology, adds an isolation frame 4. This isolation frame 4 is installed inside the receiving chamber 2, forming a storage cavity 6 for holding ice packs with the inner wall of the box body 1, as shown in Figure 3. The storage cavity 6 has a U-shaped cross-section. The bottom of the isolation frame 4 is connected to the inner bottom wall of the box body 1 via a support rod. The isolation frame 4 mainly includes a frame 5 and layered panels 7. The frame 5 is used to carry the objects to be transported and is the main part forming the storage cavity 6 with the inner wall of the box body 1, as shown in Figure 3. The frame 5 has a hollow structure, with several slots on each side wall. Multiple layered panels 7 are arranged around the frame 5, dividing the storage cavity 6 into multiple partitioned cavities 8 for placing side ice packs, achieving uniform distribution of the ice packs. The layered panels 7 are detachably connected to the frame 5, facilitating reasonable division of the storage cavity 6 according to actual needs. Two hanging racks can be installed on both sides of the layered panels 7. The hook is used to suspend the layered plate 7 from the strip opening on the side wall of the frame 5 (not shown in the figure), thus connecting the layered plate 7 to the frame 5. Alternatively, a slot can be set on the side wall of the frame 5, and an insert plate can be set at the bottom of the layered plate 7, forming an L-shaped structure with the layered plate 7. The insert plate is inserted into the slot to connect the layered plate 7 to the frame 5. In use, first install the bottom layered plate 7 of the frame 5, place the ice pack on the layered plate 7, then install the layered plate 7 on the layered plate 7 above the layered plate 7, and then put in the ice pack. Repeat this process to place all the layered plates 7 and the side ice packs. At the same time, the layered plates 7 on two adjacent side walls of the frame 5 are staggered in the height direction, as shown in Figure 4. One layered plate 7 on one side wall is located between two adjacent layered plates 7 on the adjacent side wall, which can make the ice packs evenly distributed in all parts of the frame 5, further improving the uniformity of temperature distribution inside the box 1.

[0023] Furthermore, as shown in Figures 3-4, the ice pack melts when heated, causing water droplets to form on its surface. To facilitate the collection of these droplets, a tray 9 can be installed between the bottom of the frame 5 and the inner bottom wall of the box 1. The ice pack, originally placed at the bottom of the frame 5, is then placed on the tray 9. Four water collection trays 10 are then installed around the tray 9, directly below the layered panels 7. The layered panels 7 are also designed with perforations, meaning multiple slots are cut into them. This allows water droplets falling from the ice packs on the layered panels 7 and tray 9 to be collected in the water collection trays 10, preventing them from flowing into the box 1 and causing damage to the transported items. When the isolation rack 4 is removed from the box 1, the water tray 10 is also removed. After the water in the water tray 10 is cleaned, it is placed back into the box 1 along with the isolation rack 4. In order to improve the heat preservation effect of the box 1, the wall of the box 1 can be set as a double-layer structure, which includes an outer wall layer 11 and an inner wall layer 12. A filling cavity is formed between the outer wall layer 11 and the inner wall layer 12. The filling cavity is used to fill the heat preservation layer 13. The material of the heat preservation layer 13 is usually a composite structure of vacuum insulation board and polyurethane foam, which plays a role in heat insulation, reduces the rate of heat exchange between the inside and outside of the box, prolongs the maintenance time of the low temperature state inside the box, and improves the efficiency of refrigerated transportation.

[0024] Furthermore, as shown in Figure 3, to facilitate monitoring of the temperature inside the containment chamber 2 by transport personnel, multiple temperature sensors can be installed inside the container 1. These sensors can be distributed across various side walls of the container 1 to improve the accuracy of temperature monitoring. Simultaneously, a display screen 14 is embedded on the outer side wall of the container 1 to display the real-time temperature, historical temperature curves, and temperature alarm information inside the containment chamber 2, allowing users to promptly understand the temperature conditions inside the container. The display screen 14 is also electrically connected to a wireless communication module inside the container 1, which supports Wi-Fi, Bluetooth, and 4G / 5G. The communication protocol can transmit temperature data and equipment status information to the remote monitoring terminal and user mobile APP in real time. To ensure the hygiene and safety of the storage chamber 2, the cabinet 1 can also be equipped with an ultraviolet germicidal lamp 15. The ultraviolet germicidal lamp 15 is electrically connected to the intelligent control module and can be turned on automatically at regular intervals or manually operated by the user to sterilize and disinfect the storage room and ensure the hygiene of the environment inside the cabinet. The cabinet 1 can also be equipped with a rechargeable lithium battery pack, which powers the temperature sensor, display screen 14 and ultraviolet germicidal lamp 15. The lithium battery pack is charged through an external power adapter. At the same time, the cabinet 1 is equipped with an emergency power interface. When the lithium battery pack is depleted, an external mobile power source can be connected through the emergency power interface to ensure the normal operation of the equipment in emergency situations.
