Description

Technical Field

[0001] This utility model belongs to the technical field of energy conservation and environmental protection, and in particular relates to a new type of large-scale insulated box for aviation cold chain transportation. Background Technology

[0002] In today's logistics and transportation sector, especially in air transport, insulated containers play a crucial role. Currently, aviation cold chain insulated containers are mainly made of metal, which is widely used due to its excellent thermal insulation properties and certain mechanical strength. They can meet the stringent temperature control requirements of air transport, ensuring that sensitive goods such as pharmaceuticals and biological samples are kept within a suitable temperature range during transportation.

[0003] However, despite their significant performance advantages, metal insulated boxes also have several limitations. First, the high density of metal results in a heavier overall weight, directly increasing transportation costs, especially in air freight where the added weight significantly raises transport expenses. Second, while metal's excellent thermal conductivity is an advantage under normal temperature conditions, it becomes a drawback in extreme temperatures, as heat is rapidly transferred through the metal casing, affecting the stability of the internal temperature. Finally, the environmental impact of recycling metal insulated boxes cannot be ignored. Although the technology for recycling and reusing metal materials is mature, the entire process consumes a large amount of energy and may generate environmental pollution, which contradicts the current global emphasis on sustainable development and environmental protection. Summary of the Invention

[0004] Technical Solution: To solve the above-mentioned technical problems, this utility model provides a novel large-scale aviation cold chain transport insulated box. The insulated box has a six-sided cuboid structure, and each side is assembled with an insulation board through a mortise and tenon splicing structure. Each side of the insulation board includes a honeycomb board, a vacuum insulation board, and corrugated cardboard from the outside to the inside of the box. The corrugated cardboard has openings on its surface, and the surface of the openings is covered with a transparent film material for observing whether the internal vacuum insulation board maintains a vacuum state.

[0005] As an improvement, an ice pack is also included, which is installed on the inner side of the insulation plate after being frozen.

[0006] As an improvement, the mortise and tenon splicing structure is a hexahedral structure assembled by installing a vacuum insulation board and corrugated cardboard through an L-shaped groove plate using a honeycomb board as the base plate, followed by the sequential installation of the bottom plate, back plate, left side plate, right side plate, top plate, and door panel. The specific structure is as follows: .

[0007] As an improvement, it also includes U-shaped grooves and semi-U-shaped grooves, both used to clamp ice packs; the U-shaped groove is a groove with the same height on both sides, with a groove height of 30~70mm and a groove width of 30~70mm; the semi-U-shaped groove is a groove with one side height that is 0.5~0.6 times the groove height of the side to which it is pasted, with a groove height of 30~70mm and a groove width of 30~70mm.

[0008] As an improvement, the front and back of the insulated box are each equipped with 2 to 10 U-shaped grooves and 2 to 4 half-U-shaped grooves, while the other four sides are each equipped with 2 to 10 U-shaped grooves.

[0009] As an improvement, both the U-shaped groove and the semi-U-shaped groove are symmetrically attached to the surface of the insulation board in pairs, with an ice pack snapped between each set of grooves.

[0010] As an improvement, the thickness of the vacuum insulation panel is 15~50mm, and the thickness of the honeycomb panel is 10~30mm.

[0011] As an improvement, the vacuum insulation panel is a structure assembled from one or two panels.

[0012] As an improvement, a tray is also included, placed at the bottom of the entire insulated box, for handling and installation of the insulated box.

[0013] As an improvement, the mortise and tenon splicing structure consists of two matching Velcro straps, which are fitted together at the contacting and opposite positions of the two insulation boards after splicing. During splicing, the horizontal reserved width of one insulation board is equal to the thickness of the honeycomb board of the other insulation board being joined, and the vertical reserved width is equal to the thickness of the vacuum insulation board of the other insulation board being joined.

[0014] Beneficial effects: The insulated box proposed in this utility model replaces the conventional metal box for use in cold chain transportation, with significant advantages in reducing weight and cost. Specifically, through product lightweighting, it is only about one-third the weight of a traditional insulated box; through cost reduction, the cost is less than one-tenth of the price of a traditional metal insulated box; and by reducing transportation and operating costs, it greatly expands the market application share of the insulated box.

[0015] Furthermore, this invention incorporates a vacuum insulation panel into the insulated box. The excellent thermal conductivity of the vacuum insulation panel ensures the box's practicality, enabling its application in air cold chain transportation. Additionally, because the entire insulated box is assembled from multiple parts, different sizes can be designed according to actual needs. This allows for greater flexibility in adjusting manufacturing processes and materials, effectively controlling delivery time, shortening the production cycle, and making it highly adaptable to various applications.

[0019] The specific embodiments of this utility model will be described in further detail below with reference to the examples. These examples are used to illustrate this utility model, but are not intended to limit its scope.

[0020] See Figure 1 The present invention describes a novel large-scale aviation cold chain transport insulated box. The insulated box has a six-sided cuboid structure, and each side is assembled with an insulation board through a mortise and tenon joint structure. Each side of the insulation board includes a honeycomb board 1, a vacuum insulation board 2, and a corrugated cardboard 3 from the outside to the inside of the box. The corrugated cardboard 3 has openings 7 on its surface, and the surface of the openings 7 is covered with a transparent film material for observing whether the internal vacuum insulation board maintains a vacuum state.

[0021] This invention also includes an ice block 4, which is a structure with an internal phase change material and an external hard plastic shell. Through a cooling environment, the phase change material changes from a liquid to a semi-solid or semi-solid state. The phase change material is a conventional material in the prior art, well-known and readily available to those skilled in the art. Furthermore, it serves as a structure for maintaining a relatively cold environment. When frozen, the ice block 4 is inserted into the inner side of the insulation board to maintain a refrigerated environment. The invention also includes an ice block and an L-shaped groove plate. When frozen, the ice block is installed on the inner side of the insulation board. The L-shaped groove plate is installed around the bottom of the honeycomb panel, with its width flush with the edge of the honeycomb panel and its length equal to the thickness of the honeycomb panel.

[0022] When assembling the six sides of the insulated box, considering the installation of ice packs, this utility model designs the grooves in two ways: a U-shaped groove 6 and a semi-U-shaped groove 5. The U-shaped groove 6 has two grooves with the same height on both sides, with a groove height of 30~70mm and a groove width of 30~70mm. The semi-U-shaped groove 5 has one groove with a height of 0.5~0.6 times that of the groove on the side wall to which it is attached, with a groove height of 30~70mm and a groove width of 30~70mm.

[0023] Furthermore, on the six sides of the insulation box, the front and back sides are each equipped with multiple U-shaped grooves and multiple semi-U-shaped grooves, preferably 2 to 10 U-shaped grooves and 2 to 4 semi-U-shaped grooves, while the other four sides are each equipped with 2 to 10 U-shaped grooves. The U-shaped grooves and semi-U-shaped grooves are symmetrically attached to the surface of the insulation board in pairs, with an ice pack interlocked between each pair of grooves.

[0024] When assembling the panels, the thickness of the vacuum insulation board used in this invention is 15-50mm, and the thickness of the honeycomb board is 10-30mm. Preferably, the vacuum insulation board can be designed as a structure assembled from one or two boards, which allows for different sizes to suit different practical situations.

[0025] In addition, to increase the strength during splicing, a mortise and tenon splicing structure is adopted, consisting of two matching Velcro pieces that are fitted together and installed at the contacting and opposite positions of the two insulation boards after splicing. During splicing, the horizontal reserved width of one insulation board is equal to the thickness of the honeycomb board of the other insulation board being joined, and the vertical reserved width is equal to the thickness of the vacuum insulation board of the other insulation board being joined.

[0026] This invention also includes a tray, placed at the bottom of the entire insulated box, for handling and installation of the insulated box. In normal use, before installing the door panel, the ice pack phase changer is inserted sequentially between the U-shaped groove and the semi-U-shaped groove inside the box; each part with the semi-U-shaped groove joint is reinforced with triangular corner protectors or Velcro.

[0027] The purpose of the semi-U-shaped groove design is to facilitate the insertion of ice packs into the back panel and door panel due to the height difference of the groove on one end, while also preventing the ice packs from falling out later due to the low groove. Example 1

[0028] The insulated box has a total of six sides, which are assembled using five different specifications of splicing panels, including the bottom panel, back panel, left side panel, right side panel, top panel, and door panel. The specific design is as follows.

The vacuum insulation panel is glued to the honeycomb panel surface, leaving a certain width around the perimeter. The width is controlled according to the actual design. The distance between the vacuum insulation panel and the edge of the honeycomb panel in the width direction is (25-80mm), i.e., the spacing is the corresponding honeycomb panel thickness + vacuum insulation panel thickness. The distance between the vacuum insulation panel and the edge of the honeycomb panel in the length direction is (15-50mm). 0mm) means the spacing corresponds to the thickness of the vacuum insulation board, which is 15~50mm thick. After the vacuum insulation board is pasted, corrugated cardboard is pasted on its surface. The corrugated cardboard has openings, which are covered with transparent material to allow observation of the vacuum insulation board's condition (to determine if the vacuum has been lost) and to protect the openings.

The thickness of the vacuum insulation panel is 15~50mm. After the vacuum insulation panel is pasted, corrugated cardboard is pasted onto its surface. The corrugated cardboard has openings, which are covered with transparent material to allow observation of the vacuum insulation panel's condition (to determine if a vacuum has been lost) and to protect the openings. The corrugated cardboard has L-shaped steps, the height of which matches the thickness of the vacuum insulation panel, and the width which matches the width reserved around the perimeter. Four U-shaped grooves are pasted onto the surface of the corrugated cardboard, in the width direction, for placing and fixing the phase change material. (5) The door panel is assembled by splicing together a whole honeycomb board (honeycomb board thickness is 10~30mm), 2 or 1 vacuum insulation board, and 1 or 2 corrugated cardboard.

The distance between the vacuum insulation board and the edge of the honeycomb board in the width direction is (10~30mm). The spacing corresponds to the thickness of the honeycomb panel. On one side of the length direction (i.e., the side with the L-shaped groove), the vacuum insulation board is flush with the edge of the honeycomb panel. On the other side (i.e., the side without the L-shaped groove), the distance between the vacuum insulation board and the edge of the honeycomb panel is controlled at 10~30mm, i.e., the spacing corresponds to the thickness of the honeycomb panel, and the thickness of the vacuum insulation board is 15~50mm. After the vacuum insulation board is pasted, corrugated cardboard is pasted on the surface of the vacuum insulation board. The corrugated cardboard has openings, and the openings are covered with transparent material to observe the status of the vacuum insulation board (to determine whether the vacuum has been lost) and to protect the openings. The corrugated cardboard is designed with L-shaped steps, the height of which matches the thickness of the vacuum insulation board, and the width which matches the reserved width around the perimeter. Two U-shaped grooves and two L-shaped grooves are pasted on the surface of the corrugated cardboard, in the width direction, for placing and fixing the phase change material.

First, place the base plate flat on the tray and assemble it in the following order: base plate - back plate - left side plate - right side plate - top plate - door plate. During normal use, before installing the door plate, insert the phase change material (ice pack) into the U-shaped groove, semi-U-shaped groove and L-shaped groove plate inside the box in sequence. Use triangular corner protectors to reinforce each part where L-shaped groove plate is spliced.

[0033] The following are performance tests on the insulation box of Example 1 and the traditional insulation box, including performance and cost. The data are shown in Table 1.

[0034] Table 1 shows the test data on the performance and cost of the insulated box of this utility model compared with traditional insulated boxes. As shown in Table 1, the product is lightweight, weighing only one-third of the traditional integrated aviation cold chain transport insulated box, significantly reducing transportation costs. The product cost is relatively low, as the traditional integrated aviation cold chain transport insulated box has an overly complex manufacturing process with numerous matching parts, many of which are custom-made. The product of this invention has a smoother manufacturing process compared to the traditional integrated aviation cold chain transport insulated box. The single-item production cycle is short, effectively controlling delivery time. The matching materials allow for greater flexibility, enabling the design of different sizes according to requirements. Changes to the manufacturing process are less costly, while changes to the manufacturing process of the traditional integrated aviation cold chain transport insulated box are costly and time-consuming.
