Background

Cold chain transportation refers to transportation in which the transported goods are kept at a certain temperature throughout the transportation process, no matter in the links of loading, unloading, carrying, changing transportation modes, changing packaging equipment and the like. According to the amount of goods, the following two methods are mainly adopted by the global cold chain transportation industry to transport the goods at present.

For small batches of goods, incubators are typically used for transport. A proper amount of coolant is placed in the heat preservation box, so that the temperature in the box meets the temperature requirement of cargo transportation.

For large quantities of goods, refrigerated trucks are typically used for transport. The refrigerator car makes the temperature of the carriage meet the temperature requirement of cargo transportation through a refrigeration system.

However, the temperature control is difficult due to the adoption of the insulation can for transportation, and the phenomenon of local overheating or supercooling is easy to occur. The refrigerator car is adopted for transportation, and the temperature difference in the refrigerator car is large due to the fact that the refrigerator car is long; in addition, when the refrigerator car needs to continuously transport goods to a plurality of destinations, the multiple door opening and closing operations of loading and unloading goods can greatly affect the temperature in the car, so that the temperature distribution in the car is uneven, and the goods are locally overcooled or overheated. Even if the transportation mode of the insulation can and the refrigerator car is adopted, the defect that the temperature is difficult to control accurately exists.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

Example one

The present embodiment provides an incubator, and referring to fig. 1 to 3, the incubator 10 includes: a case 1 and a case cover 2 connected to the case 1. The box 1 and the box cover 2 each include a frame 11 and a plate 12 provided on the frame 11. The structure of the incubator 10 may be any shape, such as a cylinder, a rectangular parallelepiped, or other irregular three-dimensional shape. In the present embodiment, the heat insulation box 10 has a rectangular parallelepiped shape, and therefore in the present embodiment, there are 6 blocks 12, of which 5 blocks 12 are provided on the frame 11 of the box body 1, and the other 1 block 12 is provided on the frame 11 of the box cover 2. These 6 panels 12 together with the frame 11 enclose an incubator 10 for accommodating goods. As shown in fig. 2, each panel 12 comprises, in sequence from outside to inside: the high-strength plate comprises an outer high-strength plate 121, an extruded plate 122, a phase-change insulation plate 123 made of phase-change materials and an inner plate 124.

In this embodiment, the outer high-strength plate 121 of the insulation can 10 is used to fix the shape of the insulation can 10 and provide high strength to the insulation can 10, thereby making the insulation can 10 pressure-resistant and impact-resistant. The extruded sheet 121 serves to preserve heat and may slow down the heat exchange between the incubator 10 and the external environment. The phase change material has a predetermined phase change temperature, and thus when the ambient temperature is higher than the phase change temperature of the phase change insulation board 123, the phase change insulation board 123 absorbs heat, and when the ambient temperature is lower than the phase change temperature of the phase change insulation board 123, the phase change insulation board 123 releases heat. Generally, the phase change temperature of the phase change insulation board can be changed by selecting different phase change materials. Since the inner panel 124 is located at the innermost portion of the incubator, the inner panel 124 is mainly used for insulating and beautifying the inner surface environment of the incubator.

The traditional insulation can only has one layer of ordinary insulation board, namely an extruded sheet, and does not have a phase change insulation board, and in the use process, in order to ensure that the insulation can is at a lower temperature, cold storage agent is usually placed in the insulation can. Before each transportation, the consumption of the coolant is calculated according to the transportation time, the external environment temperature and the quantity of the goods, and then the coolant is subjected to freezing, cold releasing and boxing operations, so that a large amount of labor and time are consumed. When the traditional insulation can is used for insulation, the freezing temperature of the coolant is far lower than the refrigerating temperature of goods, the cold releasing effect of the coolant is difficult to control, and therefore the supercooling phenomenon is easy to occur in the using process. After the goods are kept warm for a period of time, the temperature of the cold-storage agent rises and exceeds the refrigeration temperature of the goods, and then the local high temperature phenomenon occurs. However, how to avoid supercooling and overheating requires the operation method of the insulation can and the matched coolant to reach a certain level by the workers who need to pack, so the requirement on the workers is high.

When the heat preservation box 10 is used, the phase change heat preservation plate is made into one part of the structure of the heat preservation box 10, so that goods only need to be put into the box, the operation is simple, no special requirements are required for workers, a large amount of manpower and material resources are saved, and a large amount of time for freezing, releasing and packing the cold storage agent is saved (in the prior art, the cold storage agent needs to be frozen in a low-temperature cold storage for more than 12 hours before the heat preservation box is packed, the cold release is gathered in the cold storage for 8 hours, and the goods and the heat preservation box need to be placed in the cold storage for precooling in advance). Meanwhile, the problem of supercooling or overheating possibly occurring in the transportation process is solved, the direct contact between the coolant and the goods is avoided, the problem of pollution to the goods when the coolant package is broken is avoided, and the transportation method is safer.

In addition, this application makes the phase change heated board with the phase change material, not only can absorb or release the heat through the phase change, can also cooperate with the inside board to reduce the requirement to the intensity of inside board. Thus, the inner sheet can be made even as a film, and the material selection range of the inner sheet is also larger. The phase change insulation board can be matched with the extruded sheet, and plays a role in mutual reinforcement on the insulation effect. Because the phase transition process of phase transition heated board is a continuous process to the process of a sudden change, so at the whole in-process of phase transition heated board phase transition, the temperature that extruded sheet is close to one side of phase transition heated board keeps at phase transition temperature basically, and the temperature that extruded sheet kept away from one side of phase transition heated board is ambient temperature. In this case, the function of the extruded sheet to attenuate the heat transfer is enhanced.

Specifically, the phase change insulation board 123 is a solid board, and the phase change insulation board 123 is still a solid board after the phase change occurs. In this embodiment, after making the phase change insulation board 123 into the solid-state board, the phase change insulation board remains solid-state around the phase change to the structure that makes the insulation can not change because of the heat absorption of phase change insulation board with release heat, has also effectively avoided the difficult problem that phase change material leaked. In the prior art, phase change materials are typically organic materials, which are often toxic, polluting or dangerous chemicals. How to avoid the phase change material in the heat preservation box from leaking out is always a technical problem in the technical field. To overcome this technical problem, it is generally necessary to prepare a hermetic container to prevent the phase change material from leaking out with much effort and labor. In the present application, the phase-change insulation board 123 always remains solid, and the problem of leakage of the phase-change material does not exist.

Further, as shown in fig. 4, each of the panels 12 further includes a fixing frame 125, and each of the phase-change insulation panels 123 is fixed in the fixing frame 125, and then the fixing frame 125 is fixed in the frame 11. Preferably, the fixing frame 125 is made of a wooden material. Of course, the fixing frame can also be made of any other suitable material, such as plastic, metal or composite material. In the present embodiment, the fixing frame 125 made of wood is selected because the wood material is light and has a certain elasticity. The surface phase change insulation board 123 is directly contacted with the frame 11 by providing a wooden fixing frame 125 outside the phase change insulation board 123. Because the frame 11 is usually made of hard materials, the fixing frame 125 disposed between the phase change insulation board 123 and the frame 11 can provide a certain buffer for the phase change insulation board 123, so as to prevent the frame 11 from damaging the phase change insulation board 123, and the weight of the insulation box will not increase too much.

Further, as shown in fig. 3, the fixing frame 125 further includes an extension 1251 extending outward, the extruded plate 122 includes a recess 1221 fitting the extension 1251, and the extension 1251 is coupled with the recess 1221 to connect the extruded plate 122 to the fixing frame 125.

Note that in this application, "inner" and "outer" are both with respect to the incubator. The direction close to the inner accommodating space of the heat preservation box is inward, and on the contrary, the direction far away from the inner accommodating space of the heat preservation box is outward.

Further, as shown in fig. 1 and 5, the incubator 10 further includes an outer frame 13 disposed outside the cabinet 1, and the outer frame 13 serves to fix the incubator and increase the strength of the incubator.

Further, as shown in fig. 1 and 5, the incubator 10 further includes a tray 14 disposed at the bottom of the incubator for facilitating the transfer of the incubator 10. Preferably, the tray 14 is made of a wooden material because of its good strength, flexibility and moderate mass. Of course, the tray 14 may be made of any other suitable material, such as plastic, metal, or composite materials.

Specifically, the outer frame 13 includes an inwardly extending extension plate 131 at the bottom of the outer frame 13, and the extension plate 131 is positioned between the incubator 10 and the tray 14. Preferably, the box body 1, the extension plate 131 and the tray 14 are respectively provided with corresponding mounting holes, and the outer frame 13, the box body 1 and the tray 14 are connected together through the matching of the mounting holes and the bolts. The mounting hole can be a through hole or a threaded hole. Of course, the outer frame 13, the box 1 and the tray 14 may be connected together by any suitable means, such as welding, riveting or locking. Preferably, as shown in fig. 1, the top of the outer frame 13 is also provided with an extension plate 132, and mounting holes are provided on the extension plate 132 and the top of the case 1, and the outer frame 13 and the case 1 are connected together by the fitting of the mounting holes and the bolts 15. The mounting hole can be a through hole or a threaded hole. By this connection, the cabinet 1, the outer frame 13 and the tray 14 are effectively connected, so that the incubator has high strength and is not easily damaged during transportation. . The tray 14 can be conveniently carried by mechanical tools such as a forklift.

Preferably, both the outer frame 13 and the frame 11 may be made of a metal material, such as steel, aluminum alloy, copper, etc., so that the high strength of the incubator can be ensured.

Further, as shown in fig. 1 and 5, the incubator 10 further includes a slide rail 16 disposed in the cabinet 1 and located on the bottom plate of the cabinet 1, and a slide plate 17 disposed on the slide rail 16 for carrying goods. The sliding plate 17 can slide in or out of the case 1 by means of the sliding rail 16, thereby facilitating loading and unloading of goods.

Preferably, as shown in fig. 5, the cover 2 of the incubator 10 is further provided with a covering 18, and the covering 18 is wrapped around the frame 11 for improving the aesthetic feeling and the hand feeling of the cover 2.

Example two

The present embodiment provides a transportation apparatus, as shown in fig. 6, including: a refrigerator car 20, a refrigeration system 30, and an incubator 10 as described in the first embodiment above.

In the present embodiment, it is assumed that the transportation temperature range of the cargo is T1 to T2, where T1 is smaller than T2. The refrigerated vehicle begins to pre-cool before transportation, and the pre-cooling temperature is T3. When the temperature (in the incubator) is higher than the phase transition temperature T4 of the phase change material, the refrigeration system 30 is turned on to provide refrigeration to the refrigerated vehicle to reduce the temperature of the refrigerated vehicle. When the temperature (within the incubator) is below the phase change temperature T4 of the phase change material, the refrigeration system 30 is turned off so that the temperature of the refrigerated vehicle 20 slowly increases. Typically T3 is less than T1. By selecting a proper phase change material, the phase change temperature T4 of the phase change insulation board 123 of the insulation can 10 is in the range of T1-T2. In the transportation process, since the temperature T3 of the refrigerator car 20 is lower than the phase transition temperature T4, the heat stored in the phase transition insulation board 123 of the insulation can 10 is slowly released into the refrigerator car 20 through a layer-by-layer structure, that is, the phase transition insulation board 123 continuously absorbs a large amount of cold in the refrigerator car 20, and the temperature is kept at the phase transition temperature T4 for a long time. When the phase-change heat-insulation board 123 absorbs enough cold energy to generate phase change, the temperature in the heat-insulation box 10 starts to fall and is lower than the phase-change temperature T4, at this time, the refrigeration system 30 in the refrigerator car 20 is closed, the temperature in the refrigerator car 20 starts to rise, and when the temperature in the heat-insulation box 10 rises to the phase-change temperature T4, the phase-change heat-insulation board 123 of the heat-insulation box 10 starts to absorb the heat of the refrigerator car, which is equivalent to release the cold energy, so that the temperature in the heat-insulation box 10 is maintained at the phase-change temperature T4. When the temperature of the insulated cabinet 10 begins to rise above the phase transition temperature T4, the refrigeration system 30 is turned on to provide cool air to the refrigerated vehicle 20 to lower the temperature of the refrigerated vehicle 20 and the insulated cabinet 10. The circulation path of the cold air in the refrigerator car 20 is substantially as shown by the arrow in fig. 1, i.e., a — > B — > C — > D — > a. It should be understood that the duration of the phase change insulation board 123 phase change is determined by the material, structure and size of the phase change insulation board 123. The material, structure or size of the phase change insulation board can be changed according to the actually required phase change duration by a person skilled in the art.

Through the above circulation, the temperature of the thermal insulation box 10 can be accurately controlled within the range of T4 +/-Delta T, wherein the temperature fluctuation Delta T can be any value of 0-3 ℃, such as 0 ℃, 0.1 ℃, 0.5 ℃, 1 ℃, 1.5 ℃, 2 ℃, 2.5 ℃ or 3 ℃. For example, assuming that the transportation temperature range of the goods is 2 ℃ to 8 ℃, a suitable phase-change material can be selected to make the phase-change temperature T4 of the phase-change insulation board 123 be 5 ℃, so that the transportation temperature of the goods can be completely made to be 2 ℃ to 8 ℃. And the pre-cooling temperature T3 of the refrigerator car may be 0 ℃. Of course, the transportation temperature requirements of the goods are different, the phase change temperature of the selected phase change insulation board 123 is also different, and the pre-cooling temperature of the selected refrigerator car 20 is also different. The transportation device provided by the application can accurately control the transportation temperature within a small range approximately centered on the phase change temperature, and the value of the temperature floating delta T is within the range of 0-3 ℃.

Specifically, as shown in fig. 7, the refrigeration system 30 includes:

a temperature detection unit 301 for detecting the temperature of the thermal container 10 and transmitting the temperature in the form of a wireless signal;

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

a GPS unit 303 connected to the signal receiving unit 302 for sending the temperature to the temperature monitoring platform 304;

the temperature monitoring platform 304 is used 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, for receiving a control signal of the GPS unit 303 and controlling the cooling unit 306 to be turned on and off; and

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

In the embodiment, the temperature monitoring platform 304 is usually disposed in a company, and the GPS unit 303 is disposed on the transportation device, so that the temperature of the transportation device can be remotely monitored, recorded and controlled through data communication between the GPS unit 303 and the temperature monitoring platform 304, and the transportation device is ensured to be in a normal operation state.

Further, as shown in fig. 7, the refrigeration system 30 further includes:

and an alarm unit 307, connected to the control unit 305, for giving an alarm when the temperature is still not within the preset temperature range after the GPS command is given for a predetermined time. Typically, the alarm comprises an audible and/or light alarm to alert the driver to enter an emergency procedure. The emergency procedure comprises: (1) checking whether the temperature control system has a fault, and if the temperature control system has no fault, performing manual operation; (2) if the temperature control system fails, the driver contacts the temperature monitoring platform in time to arrange other vehicles for goods handover; (3) and the fault vehicle goes to a specified place to be checked and repaired. Through this embodiment, can in time discover and handle the trouble of conveyer to provide effectual trouble treatment measure, ensure the safety of freight.

EXAMPLE III

This embodiment provides a transportation method, which is suitable for the transportation device described in the second embodiment. As shown in fig. 8, the method comprises the steps of:

s1, placing the heat preservation box 10 into a refrigeration house with a first preset temperature for precooling before transporting goods;

s2, starting the refrigerating system 30 of the transportation device to pre-cool the refrigerated vehicle 20 to a second preset temperature;

s3, loading the goods into the precooled heat preservation box 10 at a first preset temperature and sealing the box;

s4, moving the heat preservation box 10 into the refrigerated vehicle 20 and sealing the door of the vehicle; and

s5, shipping and continuously cooling during transportation to make the temperature of the refrigerator car 20 and the incubator 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 a temperature range required for the transportation of the cargo. For example, assuming that the temperature range required for the transportation of the goods is 2 ℃ to 8 ℃, the first preset temperature may be selected to be any temperature in the range of 2 ℃ to 8 ℃, and the second preset temperature may be 0 ℃. Thus, as explained in the second embodiment, the transport method provided by the present application not only can accurately control the temperatures of the refrigerator car and the thermal insulation box, but also can increase the precooling temperature of the thermal insulation box. In the prior art, the cold storage agent is generally required to be placed in a refrigeration house with the temperature lower than the temperature required for the transportation of goods for a long time, and the cold is released for more than 8 hours at the temperature of the transportation of the goods, and the goods must be loaded into a pre-cooled insulated box at the temperature of the transportation of the goods. Therefore, in the prior art, the operator needs to work in an extremely low temperature environment, which is likely to damage the health of the staff and increase the cost of the enterprise. The cold storage agent is not required to be frozen at low temperature completely, so that the low-temperature refrigeration house can be opened less or even not, energy is saved, the freezing and cold releasing time of the cold storage agent can be saved, the working environment of operators is improved, the loading efficiency is improved, and the operation cost is reduced.

It should be understood that in the present application, "first" and "second" are not used to indicate a serial number, have no chronological relationship, and are used to distinguish between the same terms.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
