Description

Technical Field

[0001] The utility model belongs to the technical field of cold chain transportation, and particularly relates to a cold chain transportation insulation and refrigeration box. Background Art

[0002] Cold chain transportation refers to the transportation in which the goods being transported always maintain a certain temperature throughout the transportation process, including handling, changing the transportation mode, replacing packaging equipment, etc. Cold chain transportation has good preservation effect and long preservation period, so it is widely used in the transportation of the food and pharmaceutical industries. The refrigeration box is one of the equipment for cold chain transportation. Due to its portability and small size, it has become the main cold chain transportation equipment.

[0003] In the prior art, there is a combined refrigeration box for cold chain transportation, with the application date: 2024 / 08 / 20; application number: 2024220173750, which includes several refrigeration units connected in sequence. The refrigeration unit includes a box body, a bottom plate and a box cover. The box body and the box cover enclose a cavity. The bottom plate divides the cavity into a storage cavity and a refrigeration cavity. Corresponding to the refrigeration cavity, there are a grid-shaped support plate, an interface and a joint. The interface and the joint are relatively arranged on the box body. The grid-shaped support plate is provided with a number of air vents one and air vents two respectively communicating with the interface and the joint to form an inlet flow channel and an outlet flow channel. The bottom plate is correspondingly provided with a number of through holes one and through holes two respectively corresponding to the inlet flow channel and the outlet flow channel. By continuously circulating cold air in the inlet flow channel, storage cavity and outlet flow channel of different refrigeration units, the goods inside are cooled and preserved. The disadvantage is that since the cold air circulates in the storage cavities of different refrigeration units, the phenomenon of odor mixing easily occurs, affecting the product quality and unable to ensure the storage quality of the goods. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a cold chain transportation insulation and refrigeration box, which can make full use of the cargo compartment space and effectively avoid the phenomenon of odor mixing.

[0005] The purpose of the utility model is achieved as follows: A cold chain transportation insulation and refrigeration box, connected to a refrigeration device, includes several refrigeration units connected in sequence. The refrigeration unit includes a box body, a bottom plate and a box cover. The box body and the box cover enclose a cavity. The bottom plate divides the cavity into a storage cavity and a refrigeration cavity. Corresponding to the refrigeration cavity, there are a grid-shaped support plate, an interface and a joint. The interface and the joint are relatively arranged on the box body. The grid-shaped support plate is provided with a number of air vents that can communicate with the interface and the joint to form a coiled refrigeration channel. The upper side of the bottom plate is provided with a number of vertically distributed convex ribs.

[0006] When the utility model is in use, goods with the same delivery requirement are placed in the same refrigeration unit. Multiple refrigeration units are stacked in the cargo compartment in the order of delivery. The first refrigeration unit is connected to the refrigeration equipment and adjacent two refrigeration units are interconnected. Finally, the refrigeration equipment is started. Cold air sequentially passes through the interface, the refrigeration channel and the joint, and exchanges heat with the goods through the air conduction of the bottom plate and the storage cavity. Subsequently, the cold air enters the refrigeration cavity of the next refrigeration unit for temperature reduction and freshness preservation operation, and this cycle repeats until the last refrigeration unit is reached. Compared with the prior art, the beneficial effects of the utility model are as follows: the cavity is divided into independent storage cavities and refrigeration cavities that do not affect each other through the bottom plate, which can avoid the odor mixing phenomenon caused by the circulation of cold air in different refrigeration units and ensure the original quality of the product; the refrigeration channel adopts a coiled snake-like design, which can increase the circulation time of cold air in the refrigeration cavity, thereby improving the refrigeration efficiency; the goods are separated from the bottom plate by the convex ribs at a certain distance, providing a certain support space for the convection of heat exchange and being beneficial to further improving the refrigeration effect; this refrigerated box can exist as an individual unit or multiple refrigeration units can be interconnected for use, avoiding the random stacking of goods in the cargo compartment and improving the space utilization rate of the cargo compartment.

[0007] As a further improvement of the utility model, a rotatable drainage fan is provided corresponding to the interface.

[0008] As a further improvement of the utility model, several of the convex ribs are evenly distributed on the bottom plate.

The refrigeration unit includes a box body 1, a bottom plate 2, and a box cover 3. The box body 1 and the box cover 3 enclose to form a cavity. The bottom plate 2 divides the cavity into a storage cavity and a refrigeration cavity. Corresponding to the refrigeration cavity, there are a grid-shaped support plate 4, an interface 101, and a joint 102. The interface 101 and the joint 102 are oppositely arranged on the box body 1. A number of ventilation ports 401 are opened on the grid-shaped support plate 4 and can be connected to the interface 101 and the joint 102 to form a coiled refrigeration channel. A rotatable drainage fan 5 is arranged corresponding to the interface 101. Specifically, the grid-shaped support plate 4 includes a number of first partitions 402 horizontally distributed at equal intervals and a number of second partitions 403 vertically distributed at equal intervals. Reinforcement blocks 404 are arranged at both ends of the first partition 402 to improve its own stability. A number of vertically distributed convex ribs 6 are arranged on the upper side of the bottom plate 2. Preferably, a number of convex ribs 6 are equally spaced on the bottom plate 2.

[0021] In this embodiment, a first thermal insulation layer 7 is provided on the outer side of the box body 1, and a second thermal insulation layer 8 is provided on the outer side of the box cover 3, which can reduce the loss of cold air in the box, thereby reducing the loss of the refrigeration equipment and achieving the effect of energy conservation.

The rightmost joint 102 is connected to the adjacent joint 102 through a first hose 9 to form a closed structure. The leftmost interface 101 is connected to the adjacent interface 101 through a second hose to form a closed structure, so that the cold air can be continuously recycled for refrigeration. In actual use, the number of stacked refrigeration units can be adjusted according to the height of the cargo compartment to achieve the highest space utilization rate of the cargo compartment. Preferably, two symmetrically distributed positioning grooves 10 are provided at the bottom of the first thermal insulation layer 7, and two positioning bars 11 corresponding to the two positioning grooves 10 are provided at the top of the second thermal insulation layer 8.
