Hereinafter, the technical solution in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments that a person skilled in the art can think of without requiring creative efforts are within the protection scope of the present invention.

Example 1
This embodiment provides a heat insulation box, and as shown in FIGS. 1 to 3, the heat insulation box 10 includes a main body 1,
And a lid 2 connected to the main body 1. Both the main body 1 and the lid body 2 include a frame 11 and a panel 12 installed on the frame 11. The structure of the heat insulating box 10 may have any shape, for example, a cylindrical shape, a rectangular shape, or other irregular three-dimensional shape. In the present embodiment, since the heat insulation box 10 has a rectangular shape, the present embodiment includes a total of six panels 12, of which five panels 12 are installed in the frame 11 of the main body 1 and the remaining one. The sheet of panels 12 is installed on the frame 11 of the lid 2. The six panels 12, together with the frame 11, form a heat insulation box 10 for storing cargo. As shown in FIG. 2, for each panel 12,
In order from outside to inside, an external high-strength panel 121, an extruded panel 122, a phase change heat insulating panel 123 made of a phase change material, and an internal panel 124 are included.

In the present embodiment, the external high-strength panel 121 of the heat insulation box 10 fixes the shape of the heat insulation box 10 and imparts high strength to the heat insulation box 10, thereby making the heat insulation box 10 resistant to pressure and impact. The extruded panel 121 is for heat insulation and reduces heat exchange between the heat insulation box 10 and the external environment. Since the phase change material has a constant phase change temperature, when the environmental temperature becomes higher than the phase change temperature of the phase change heat insulating panel 123, the phase change heat insulating panel 123 absorbs the amount of heat and the environmental temperature changes. When the temperature becomes lower than the phase change temperature of 123, the phase change heat insulating panel 123 emits heat. Usually, the phase change temperature of the phase change heat insulating panel can be changed by selecting different phase change materials. Since the inner panel 124 is located at the innermost side of the heat insulation box, the inner panel 124 is mainly used for heat insulation and decoration of the inner surface environment of the heat insulation box.

The conventional heat insulation box usually has only one layer of general heat insulation panel, that is, extruded panel, there is no phase change heat insulation panel, and in order to keep the heat insulation box at low temperature during use, It is common to put a cold storage agent. Each time it is transported, the amount of regenerator used is calculated according to the transportation time, the temperature of the external environment and the amount of cargo, and then the regenerator is used for freezing, cooling, and packing operations. It takes. When the conventional heat-retaining box is kept warm with the regenerator, the freezing temperature of the regenerator is much lower than the refrigerating temperature of the cargo, and the cooling effect of the regenerator is difficult to control, so the phenomenon of supercooling occurs in the process of use. It's easy to do. After the temperature is kept for a predetermined time, when the temperature of the regenerator rises above the refrigerating temperature of the cargo, it partially becomes high temperature. In order to avoid overcooling and overheating, it is necessary for the packing operator to know exactly how to operate the heat-retaining box and the matching regenerator, which increases the demands on the operator.

When the heat insulation box 10 of the present invention is used, since the phase change heat insulation panel is constructed as a part of the structure of the heat insulation box 10, it is sufficient to put the cargo in the main body, it is easy to operate, and it is easy for the operator to operate. It saves a lot of labor and physical power without special requirement, and also saves a lot of freezing, cooling and packing time by the cold storage agent (in the prior art, the cold storage agent is stored in the low temperature refrigerator before the warm box is packed). It is necessary to refrigerate for 12 hours or more, and allow it to cool in the refrigerator for a total of 8 hours, and put the cargo and heat insulation box in the refrigerator in advance to precool it). In addition, it solves the problems of overcooling and overheating that may occur during the transportation process, avoids direct contact between the cold storage agent and the cargo, and eliminates the problem of contamination of the cargo due to rupture of the packaging of the cold storage agent, thus improving safety. Raise more.

Further, in the present application, by manufacturing a phase change heat insulating panel using a phase change material, the amount of heat can be absorbed or released by the phase change, and by cooperating with the inner panel, the strength of the inner panel is required. Lower. As described above, the inner panel may be formed as a single layer film, and the selection range of the material of the inner panel is expanded. The phase change insulation panel also cooperates with the extruded panel to reinforce the insulation effect. Since the phase change process of the phase change heat insulation panel is a continuous process and not a sudden change process, the temperature on one side close to the phase change heat insulation panel of the extrusion molded panel is over the phase change process of the phase change heat insulation panel. The temperature on one side of the extruded panel that is kept at about the phase change temperature and is separated from the phase change heat insulating panel is the ambient temperature. In such a case, the heat transfer lowering function of the extruded panel is enhanced.

Specifically, the phase change heat insulation panel 123 is a solid panel, and is maintained as a solid panel even after the phase change. In this embodiment, after the phase change heat insulation panel 123 is made into a solid panel, the phase change heat insulation panel is maintained as a solid before and after the phase change, whereby the structure of the heat insulation box is caused by the heat absorption and heat dissipation of the phase change heat insulation panel. And does not change, and effectively avoids the problem of leakage of phase change material. In the prior art, phase change materials are usually organic materials, but these organic materials are generally toxic, fouling or hazardous chemicals. How to prevent leakage of the phase change material in the insulation box is a technical challenge in the art. To overcome this technical problem, it is common to manufacture sealed containers to prevent leakage of phase change material with a great deal of labor and cost. In contrast, in the present application, the phase change insulation panel 123 is maintained as a solid throughout, which completely eliminates the problem of phase change material leakage.

Further, as shown in FIG. 4, each panel 12 further includes a fixed frame 125, the phase change heat insulation panels 123 are fixed in the fixed frames 125, respectively, and then the fixed frames 125 are fixed in the frame 11. It Preferably, the fixed frame 125 is made of wood material. Of course, the fixed frame may be made of any other suitable material, such as plastic, metal or composite. In this embodiment, the wooden fixing frame 125 is used because the wooden material is lightweight and has a predetermined elasticity. A wooden fixed frame 125 is provided outside the phase change heat insulating panel 123.
Is installed, the phase-change heat insulation panel 123 on the surface is brought into direct contact with the frame 11. Since the frame 11 is usually made of a hard material, the fixed frame 125 installed between the phase-change heat insulation panel 123 and the frame 11 provides a predetermined cushion to the phase-change heat insulation panel 123, so that the frame 11 does not interfere with the phase-change heat insulation panel 123. The phase change heat insulation panel 123 is prevented from being damaged, and the weight of the heat insulation box is not significantly increased.

Further, as shown in FIG. 3, the fixed frame 125 further includes an extending portion 125 extending outward.
1, the extruded panel 122 includes a recess 1221 blended with a stretch 1251;

In the present application, both “inside” and “outside” refer to the heat insulation box. The direction close to the internal storage space of the heat insulation box is inward, and the direction away from the internal storage space of the heat insulation box is outward.

Further, as shown in FIGS. 1 and 5, the heat insulation box 10 further includes an outer frame 13 installed outside the main body 1, and the outer frame 13 fixes the heat insulation box and enhances the strength of the heat insulation box.

Further, as shown in FIGS. 1 and 5, the insulation box 10 further comprises a pallet 14 installed at the bottom thereof to facilitate the transportation of the insulation box 10. Preferably, the pallet 14 is made of wood material, as the wood material has good strength, elasticity, and suitable mass. Of course, the pallet 14 may be made of any other suitable material, such as plastic, metal or synthetic material.

Specifically, the outer frame 13 includes a stretch plate 131 located at the bottom of the outer frame 13 and extending inward. The stretch plate 131 is located between the heat insulation box 10 and the pallet 14. Preferably the body 1,
Corresponding mounting holes are provided in the stretching plate 131 and the pallet 14, respectively, and the outer frame 13, the main body 1 and the pallet 14 are integrally connected by fitting the mounting holes and the bolts. The mounting hole may be a through hole or a screw hole. Of course, the outer frame 13, the body 1 and the pallet 14 may be connected together in any other suitable manner, for example by welding, caulking or buckling. Preferably, as shown in FIG. 1, a stretch plate 132 is also installed on the top of the outer frame 13, a mounting hole is installed on the top of the stretch plate 132 and the main body 1, and the outer hole is formed by fitting the mounting hole and the bolt 15. The frame 13 and the main body 1 are integrally connected. The mounting hole may be a through hole or a screw hole. With such a connection method, the main body 1, the outer frame 13 and the pallet 14 are securely connected to each other to give the heat insulation box high strength, thereby avoiding damage during the transportation process. The pallet 14 is useful for transporting the heat insulation box by a mechanical tool such as a forklift.

Preferably, both the outer frame 13 and the frame 11 are made of a metal material such as steel, aluminum alloy, copper or the like, and thus high strength of the heat insulation box is ensured.

Example 2
The present embodiment provides a transportation device, and as shown in FIG. 6, the transportation device includes a refrigerating vehicle 20, a cooling system 30, and the heat insulation box 10 described in the first embodiment.

In this embodiment, the freight transportation temperature range is T1 to T2, where T1 is smaller than T2. Before transportation, the refrigerated vehicle starts to be precooled at the precooling temperature T3. When the temperature (in the warm box) becomes higher than the phase change temperature T4 of the phase change material, the cooling system 30 is activated to provide the refrigerating vehicle with a quantity of cold energy to lower the temperature of the refrigerating vehicle. When the temperature (in the heat insulation box) becomes lower than the phase change temperature T4 of the phase change material, the cooling system 30 is stopped and the temperature of the refrigerating vehicle 20 gradually rises. Normal,
T3 is smaller than T1. By selecting an appropriate phase change material, the phase change temperature T4 of the phase change heat insulating panel 123 of the heat insulating box 10 is set within the range of T1 to T2. 20 refrigerated vehicles during the transportation process
Since the temperature T3 is smaller than the phase change temperature T4, the amount of heat stored in the phase change heat insulating panel 123 of the heat insulating box 10 is gradually released to the refrigerating vehicle 20 through the structure of a plurality of layers. The panel 123 continuously absorbs a large amount of cold energy in the refrigerating vehicle 20 and keeps the temperature at the phase change temperature T4 for a long time. When the phase-change heat insulation panel 123 absorbs a sufficient amount of cold heat and undergoes a phase change, the temperature in the heat insulation box 10 decreases until it becomes lower than the phase-change temperature T4, at which time the cooling system 30 in the refrigeration vehicle 20 is stopped. Then, the temperature inside the refrigerating vehicle 20 starts to rise,
When the temperature inside the heat insulation box 10 rises to the phase change temperature T4, the phase change heat insulation panel 123 of the heat insulation box 10 absorbs the heat quantity of the refrigerating vehicle, that is, releases the cold heat quantity, and the temperature inside the heat insulation box 10 is phased. The change temperature T4 is maintained and, thus, continues until the phase change ends. When the temperature of the heat insulation box 10 becomes higher than the phase change temperature T4, the cooling system 30 is activated to provide cold air to the refrigeration vehicle 20 and lower the temperatures of the refrigeration vehicle 20 and the heat insulation box 10. The circulation route of cold air in the refrigerating vehicle 20 is shown in FIG.
Is shown, that is, A->B->C->D->A. In addition,
Regarding the phase change duration of the phase change heat insulating panel 123, the material of the phase change heat insulating panel 123,
It depends on the structure and dimensions. One of ordinary skill in the art can modify the material, structure or dimensions of the phase change insulation panel depending on the desired phase change duration.

By the above circulation, the temperature of the heat insulation box 10 is accurately controlled within the range of T4±ΔT, and the value of the temperature fluctuation ΔT is any value from 0 to 3° C., for example, 0° C. or 0.1° C. , 0.5°C, 1
C, 1.5 C, 2 C, 2.5 C or 3 C. For example, the freight transportation temperature range is 2℃
If it is 8° C., an appropriate phase change material is selected, and the phase change temperature T4 of the phase change heat retaining panel 123 is selected.
When the temperature is set to 5°C, the transportation temperature of the cargo can be set to 2°C to 8°C. In this case, the pre-cooling temperature T3 of the refrigerating vehicle may be 0°C. Of course, if the transportation temperature required for the cargo is different, the phase change temperature of the selected phase change heat insulation panel 123 is also different, and the precooling temperature of the selected refrigeration vehicle 20 is also different. However, in the transport apparatus according to the present application, the transport temperature is accurately controlled within a small range centered around the phase change temperature, and the value of the temperature variation ΔT remains in the range of 0 to 3°C.

A cooling unit 306 for cooling under the control of the control unit 305.

In this embodiment, the temperature monitoring platform 304 is usually installed in a company, but the GPS unit 303 is installed in the transportation device, and the data communication between the GPS unit 303 and the temperature monitoring platform 304 enables the temperature of the transportation device to be monitored. Long-distance monitoring, recording and control are realized to ensure the normal operating condition of the transportation device.

Further, as shown in FIG. 7, the cooling system 30 further comprises:
The alarm unit 307 is connected to the control unit 305 and transmits an alarm when the temperature is still outside the predetermined temperature range after a predetermined time has passed since the GPS command was transmitted. Typically, the alert includes a voice and/or light alert to alert the driver to take emergency action. The emergency procedures include: (1) It is detected whether or not a failure has occurred in the temperature control system, and if there is no failure, it is manually operated. (2) When the temperature control system is stopped, the driver communicates with the temperature monitoring platform in a timely manner to procure other vehicles and deliver the cargo. (3) The faulty vehicle will go to a designated location for inspection and maintenance. According to the present embodiment, it is possible to detect a failure of the transportation device in real time and deal with the failure, and provide an effective troubleshooting measure, thus ensuring the transportation safety of the cargo.
