Description

Insulation box, transportation device and transportation method

Technical Field

The present invention relates to the field of cold chain transportation technology, and in particular to an insulation box, a transportation device and a transportation method.

Background Art

Cold chain transportation refers to ensuring that goods are kept at a constant temperature throughout the entire transportation process, including loading and unloading, changing transportation methods, and replacing packaging equipment. The global cold chain transportation industry currently utilizes two main methods, depending on the volume of goods.

For small quantities of goods, we usually use thermal insulation boxes for transportation. An appropriate amount of refrigerant is placed in the thermal insulation box to ensure that the temperature inside the box meets the temperature requirements for cargo transportation.

Large quantities of goods are usually transported in refrigerated trucks, which use a refrigeration system to keep the temperature of the truck compartment consistent with the temperature requirements for transporting the goods.

However, transporting goods in insulated containers is difficult to control temperature, making it prone to localized overheating or overcooling. Transporting goods in refrigerated trucks, due to their length, can lead to significant temperature differences within the vehicle. Furthermore, when refrigerated trucks are constantly transporting goods to multiple destinations, the frequent opening and closing of the door during loading and unloading significantly impacts the temperature inside the vehicle, leading to uneven temperature distribution and the risk of localized overheating or overcooling. Even transporting goods in insulated containers and refrigerated trucks still suffers from the difficulty of precise temperature control.

DETAILED DESCRIPTION

The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

Example 1

The present embodiment provides an insulated box, see Figures 1 to 3, the insulated box 10 includes: a box body 1 and a box cover 2 connected to the box body 1. The box body 1 and the box cover 2 both include a frame 11 and a plate 12 arranged on the frame 11. The structure of the insulated box 10 can be any shape, such as a cylindrical, rectangular or other irregular three-dimensional shape. In the present embodiment, the insulated box 10 is a rectangular parallelepiped, so in this embodiment, there are a total of 6 plates 12, 5 of which are arranged on the frame 11 of the box body 1, and the other plate 12 is arranged on the frame 11 of the box cover 2. These 6 plates 12 and the frame 11 together form an insulated box 10 for accommodating goods. As shown in Figure 2, each plate 12 includes, from the outside to the inside, an external high-strength plate 121, an extruded plate 122, a phase change insulation plate 123 made of phase change material, and an internal plate 124.

In this embodiment, the external high-strength plate 121 of the thermal insulation box 10 is used to fix the shape of the thermal insulation box 10 and to make the thermal insulation box 10 have high strength, so that the thermal insulation box 10 is pressure-resistant and impact-resistant. The extruded plate 121 is used for heat preservation and can slow down the heat exchange between the thermal insulation box 10 and the external environment. Phase change materials all have a predetermined phase change temperature. Therefore, when the ambient temperature is higher than the phase change temperature of the phase change thermal insulation plate 123, the phase change thermal insulation plate 123 absorbs heat, and when the ambient temperature is lower than the phase change temperature of the phase change thermal insulation plate 123, the phase change thermal insulation plate 123 releases heat. Generally, the phase change temperature of the phase change thermal insulation plate can be changed by selecting different phase change materials. Since the internal plate 124 is located at the innermost part of the thermal insulation box, the internal plate 124 is mainly used for heat preservation and beautifying the inner surface environment of the thermal insulation box.

Traditional insulated boxes typically consist of only a single layer of standard insulation board, typically extruded polystyrene, without phase-change insulation. To maintain a low temperature during use, refrigerant is often placed inside the box. Before each shipment, the amount of refrigerant required must be calculated based on the shipping time, ambient temperature, and cargo volume. The refrigerant is then chilled, released, and packed, consuming significant labor and time. When using refrigerant for insulation in traditional insulated boxes, the refrigerant's freezing temperature is far below the refrigerated storage temperature of the cargo, making its release difficult to control. This can lead to overcooling during use. After a period of insulation, the refrigerant's temperature rises and exceeds the refrigerated storage temperature of the cargo, resulting in localized overheating. Preventing both overcooling and overheating requires a high level of proficiency in the operation of the insulated box and the accompanying refrigerant, placing high demands on the personnel performing the task.

When the insulated box 10 of the present invention is in use, since the phase change insulation board has been made into a part of the structure of the insulated box 10, it is only necessary to load the goods into the box. The operation is simple and there are no special requirements for the staff. This saves a lot of manpower and material resources, and also saves the time of freezing, releasing and packing the large amount of coolant (in the prior art, the coolant needs to be frozen in a low-temperature cold storage for more than 12 hours before packing, and then released in the cold storage for 8 hours. The goods and the insulated box need to be placed in the cold storage for pre-cooling in advance). At the same time, it solves the problem of overcooling or overheating that may occur during transportation, avoids direct contact between the coolant and the goods, and eliminates the problem of contamination of the goods when the coolant packaging is broken, which is safer.

In addition, the present application makes the phase change material into a phase change insulation board, which can not only absorb or release heat through phase change, but also cooperate with the internal board, thereby reducing the strength requirements of the internal board. In this way, the internal board can even be made into a layer of film, and the range of material selection for the internal board is also wider. The phase change insulation board can also cooperate with the extruded board to enhance each other in the insulation effect. Since the phase change process of the phase change insulation board is a continuous process, not a sudden process, during the entire phase change process of the phase change insulation board, the temperature of the side of the extruded board close to the phase change insulation board is basically maintained at the phase change temperature, while the temperature of the side of the extruded board away from the phase change insulation board is the ambient temperature. In this case, the function of the extruded board to reduce heat transfer is enhanced.

Specifically, the phase change insulation board 123 is a solid board, and the phase change insulation board 123 remains a solid board after the phase change occurs. In this embodiment, after the phase change insulation board 123 is made into a solid board, the phase change insulation board remains in a solid state before and after the phase change, so that the structure of the insulation box will not change due to the heat absorption and heat release of the phase change insulation board, and the problem of phase change material leakage is effectively avoided. In the prior art, phase change materials are usually organic materials, and these organic materials are usually toxic, polluting or dangerous chemicals. How to prevent the phase change material in the insulation box from leaking has always been a technical problem in this technical field. In order to overcome this technical problem, it is usually necessary to spend a lot of manpower and financial resources to prepare a sealed container to prevent the phase change material from leaking. In the present application, the phase change insulation board 123 always remains in a solid state, and there is no problem of phase change material leakage at all.

Furthermore, as shown in Figure 4, each panel 12 also includes a fixing frame 125. Each phase change insulation panel 123 is fixed within the fixing frame 125, which is then fixed within the frame 11. Preferably, the fixing frame 125 is made of wood. Of course, the fixing frame can also be made of any other suitable material, such as plastic, metal, or composite materials. In this embodiment, a wooden fixing frame 125 is selected because wood is lightweight and has a certain degree of elasticity. By providing a wooden fixing frame 125 outside the phase change insulation panel 123, the surface phase change insulation panel 123 is directly in contact with the frame 11. Because the frame 11 is generally made of a hard material, the fixing frame 125 provided between the phase change insulation panel 123 and the frame 11 can provide a certain cushioning effect for the phase change insulation panel 123, preventing damage to the phase change insulation panel 123 by the frame 11, while also not significantly increasing the weight of the insulation box.

Furthermore, as shown in FIG3 , the fixing frame 125 further includes an outwardly extending extension portion 1251 , and the extruded plate 122 includes a recessed portion 1221 adapted to the extension portion 1251 . The extension portion 1251 is coupled to the recessed portion 1221 to connect the extruded plate 122 to the fixing frame 125 .

Please note that in this application, "inside" and "outside" are relative to the thermal insulation box. The direction close to the internal storage space of the thermal insulation box is inward, and conversely, the direction away from the internal storage space of the thermal insulation box is outward.

Furthermore, as shown in FIG1 and FIG5 , the heat preservation box 10 further includes an outer frame 13 provided outside the box body 1 , and the outer frame 13 is used to fix the heat preservation box and increase the strength of the heat preservation box.

Furthermore, as shown in Figures 1 and 5 , the insulated box 10 also includes a tray 14 disposed at the bottom of the insulated box for convenient transport of the insulated box 10. Preferably, the tray 14 is made of wood, as wood has good strength, elasticity, and moderate quality. Of course, the tray 14 may also be made of any other suitable material, such as plastic, metal, or a synthetic material.

Specifically, the outer frame 13 includes an inwardly extending extension plate 131 located at the bottom of the outer frame 13. The extension plate 131 is positioned between the thermal insulation box 10 and the tray 14. Preferably, corresponding mounting holes are provided on the box body 1, the extension plate 131, and the tray 14. The mounting holes engage bolts to connect the outer frame 13, the box body 1, and the tray 14. The mounting holes can be through-holes or threaded holes. Of course, the outer frame 13, the box body 1, and the tray 14 can also be connected by any suitable means, such as welding, riveting, or snap fastening. Preferably, as shown in FIG1 , the top of the outer frame 13 is also provided with an extension plate 132. Mounting holes are provided on the extension plate 132 and on the top of the box body 1. The mounting holes engage bolts 15 to connect the outer frame 13 and the box body 1. The mounting holes can be through-holes or threaded holes. This connection method effectively connects the box body 1, the outer frame 13, and the tray 14, providing a high degree of strength and making it less susceptible to damage during transportation. The pallet 14 can be used to easily transport the thermal insulation box using mechanical tools such as a forklift.

Preferably, both the outer frame 13 and the frame 11 can be made of metal materials, such as steel, aluminum alloy, copper, etc., so as to ensure that the thermal insulation box has high strength.

1 and 5 , the thermal insulation box 10 further includes a slide rail 16 disposed within the box body 1 and located on the bottom plate of the box body 1, and a sliding plate 17 disposed on the slide rail 16 for carrying goods. The sliding plate 17 can slide into or out of the box body 1 via the slide rail 16, thereby facilitating loading and unloading of goods.

Preferably, as shown in FIG. 5 , the box cover 2 of the thermal insulation box 10 is further provided with a rim 18 , which is wrapped around the outer periphery of the frame 11 to improve the aesthetics and feel of the box cover 2 .

Example 2

This embodiment provides a transport device, as shown in FIG6 , which includes a refrigerated truck 20 , a refrigeration system 30 , and the thermal insulation box 10 described in the first embodiment.

In this embodiment, it is assumed that the transportation temperature range of the goods is T1 to T2, where T1 is less than T2. The refrigerated truck begins pre-cooling before transportation, and its pre-cooling temperature is T3. When the temperature (inside the insulation box) is higher than the phase change temperature T4 of the phase change material, the refrigeration system 30 is turned on to provide cooling for the refrigerated truck, thereby lowering the temperature of the refrigerated truck. When the temperature (inside the insulation box) is lower than the phase change temperature T4 of the phase change material, the refrigeration system 30 is turned off, so that the temperature of the refrigerated truck 20 slowly rises. Usually T3 is less than T1. By selecting a suitable phase change material, the phase change temperature T4 of the phase change insulation plate 123 of the insulation box 10 is within the range of T1 to T2. During transportation, since the temperature T3 of the refrigerated truck 20 is lower than the phase transition temperature T4, the heat stored in the phase change insulation panels 123 of the insulated box 10 is slowly released into the refrigerated truck 20 through a layer-by-layer structure. This means that the phase change insulation panels 123 continuously absorb a large amount of the cold energy within the refrigerated truck 20, maintaining the temperature at the phase transition temperature T4 for a long period of time. When the phase change insulation panels 123 have absorbed enough cold energy to undergo a phase transition, the temperature within the insulated box 10 begins to drop and falls below the phase transition temperature T4. At this point, the refrigeration system 30 within the refrigerated truck 20 shuts down, and the temperature within the refrigerated truck 20 begins to rise. When the temperature within the insulated box 10 reaches the phase transition temperature T4, the phase change insulation panels 123 of the insulated box 10 begin absorbing heat from the refrigerated truck, effectively releasing cold energy, keeping the temperature within the insulated box 10 at the phase transition temperature T4 until the phase transition is complete. When the temperature of the insulated box 10 begins to exceed the phase transition temperature T4, the refrigeration system 30 activates, providing cold air to the refrigerated vehicle 20 to reduce the temperature of the refrigerated vehicle 20 and the insulated box 10. The cold air circulates through the refrigerated vehicle 20 as shown by the arrows in Figure 1: A->B->C->D->A. It should be understood that the duration of the phase transition of the phase-change insulation panel 123 is determined by the material, structure, and dimensions of the phase-change insulation panel 123. Those skilled in the art may modify the material, structure, or dimensions of the phase-change insulation panel based on the desired phase transition duration.

Through the above cycle, the temperature of the insulation box 10 can be precisely controlled within the range of T4±ΔT, where the temperature fluctuation ΔT can be any value between 0 and 3°C, such as 0°C, 0.1°C, 0.5°C, 1°C, 1.5°C, 2°C, 2.5°C, or 3°C. For example, assuming that the transportation temperature range of the goods is 2°C to 8°C, a suitable phase change material can be selected to make the phase change temperature T4 of the phase change insulation plate 123 5°C, which can completely keep the transportation temperature of the goods between 2°C and 8°C. At this time, the pre-cooling temperature T3 of the refrigerated truck can be 0°C. Of course, the phase change temperature of the selected phase change insulation plate 123 and the pre-cooling temperature of the selected refrigerated truck 20 will also be different depending on the transportation temperature requirements of the goods. However, what remains unchanged is that through the transportation device provided by this application, the transportation temperature can be precisely controlled within a very small range roughly centered on the phase change temperature, and the temperature fluctuation ΔT is within the range of 0 to 3°C.

Specifically, as shown in FIG7 , the refrigeration system 30 includes:

The temperature detection unit 301 is used to detect the temperature of the insulated box 10 and send the temperature in the form of a wireless signal;

a signal receiving unit 302 for wirelessly receiving the wireless signal and sending the temperature to the GPS unit 303;

The GPS unit 303 is connected to the signal receiving unit 302 and is used to send the temperature to the temperature monitoring platform 304;

a temperature monitoring platform 304 for monitoring and recording the temperature and sending a GPS instruction to the GPS unit 303 when the temperature is not within a preset temperature range;

a control unit 305 connected to the GPS unit 303, configured to receive control signals from the GPS unit 303 and control the opening and closing of the refrigeration unit 306; and

The refrigeration unit 306 is used for refrigeration under the control of the control unit 305 .

In this embodiment, the temperature monitoring platform 304 is usually set up in the company, and the GPS unit 303 is on the transportation device. Through data communication between the GPS unit 303 and the temperature monitoring platform 304, remote monitoring, recording and control of the temperature of the transportation device can be achieved to ensure that the transportation device is in normal operation.

Furthermore, as shown in FIG7 , the refrigeration system 30 further includes:

The alarm unit 307 is connected to the control unit 305 and is used to issue an alarm when the above temperature is still not within the preset temperature range after the GPS instruction is issued for a predetermined time. Usually, the alarm includes a sound and/or light alarm to remind the driver to enter the emergency procedure. The emergency procedure includes: (1) Check whether the temperature control system is faulty. If not, perform manual operation; (2) If the temperature control system is faulty, the driver promptly contacts the temperature monitoring platform and arranges other vehicles to carry out cargo delivery; (3) The faulty vehicle goes to the designated location for inspection and repair. Through this embodiment, the fault of the transportation device can be discovered and handled in a timely manner, and effective fault handling measures can be provided to ensure the safety of cargo transportation.

Example 3

This embodiment provides a transportation method, which is applicable to the transportation device described in the above embodiment 2. As shown in Figure 8, the method includes the following steps:

S1, before transporting the goods, the insulated box 10 is placed in a cold storage with a first preset temperature for pre-cooling;

S2, turning on the refrigeration system 30 of the transport device to pre-cool the refrigerated truck 20 to a second preset temperature;

S3, loading the goods into the pre-cooled insulation box 10 at the first preset temperature and sealing the box;

S4, moving the insulated box 10 into the refrigerated truck 20 and sealing the door; and

S5, shipping and continuing refrigeration during transportation to keep the temperature of the refrigerated truck 20 and the insulation box 30 within a preset temperature range.

Typically, the first predetermined temperature is higher than the second predetermined temperature, and the first predetermined temperature is within the temperature range required for cargo transportation. For example, assuming the required temperature range for cargo transportation is 2°C to 8°C, the first predetermined temperature can be selected from any temperature within the range, and the second predetermined temperature can be 0°C. Thus, as described in Example 2 above, the transportation method provided by this application not only allows for precise control of the temperatures of the refrigerated truck and the insulated box, but also increases the pre-cooling temperature of the insulated box. In the prior art, the refrigerant must be placed in a cold storage at a temperature below the required temperature for a long period of time, then cooled for at least eight hours at the cargo transportation temperature. Furthermore, the cargo must be loaded into the pre-cooled insulated box at the cargo transportation temperature. Therefore, in the prior art, operators must work in extremely low temperatures, which can be harmful to their health and increase costs for the company. However, this application eliminates the need to freeze the refrigerant at such low temperatures. Therefore, the low-temperature cold storage can be opened less frequently or even not at all, saving energy, reducing the time it takes for the refrigerant to freeze and cool, improving the operator's working environment, increasing loading efficiency, and reducing operating costs.

It should be understood that in this application, "first" and "second" are not used to indicate serial numbers and have no temporal relationship, but are only used to distinguish the same terms.

The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of the rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
