Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

The embodiment of the application provides a refrigerated transport case to be used for commodity circulation transportation's in-process to transport article and carry out low temperature storage. In particular, the transportation item may be fruits and vegetables, chilled foods, medical products, cosmetics, etc., which are not limited in this embodiment.

Referring to fig. 1 and 2, fig. 1 is a schematic structural view of a refrigerated transport case according to an embodiment of the present application, and fig. 2 is a partial sectional view of the refrigerated transport case shown in fig. 1 in an opened state. The refrigerated transport case may include a first case 100, a photovoltaic module 300, a refrigeration module 200, and a phase change cool storage module 500. The photovoltaic module 300 is at least partially disposed in the first case 100. The refrigeration assembly 200 is electrically connected with the photovoltaic assembly 300, so that the photovoltaic assembly 300 can supply power to the refrigeration assembly 200, and the refrigeration assembly 200 is at least partially arranged in the first box 100 to refrigerate in the first box 100. The phase change cool storage assembly 500 is detachably installed in the first case 100.

The phase change cold storage assembly 500 is an assembly with phase change energy storage materials. The phase change energy storage material refers to a substance which changes physical state and can provide latent heat under the condition of constant temperature. Therefore, on the one hand, the temperature in the first tank 100 may be dynamically adjusted by the characteristic that the phase change cold storage assembly 500 can absorb or release cold energy, so that the temperature control in the first tank 100 is more stable. On the other hand, the phase change cold storage assembly 500 can absorb and store a certain amount of cold energy when the power generation of the photovoltaic assembly 300 is sufficient, so as to release the energy when the photovoltaic assembly 300 stops generating power for a long time and cannot start the refrigeration assembly 200, further prolong the refrigeration time of the refrigerated transport case, reduce the probability of losing temperature in the first case 100 at night or in overcast and rainy days, and further improve the refrigeration effect of the refrigerated transport case.

It can be further appreciated that in the related art, the phase change cold storage material is generally embedded into the evaporator tube of the refrigeration assembly to form an integral structure of the evaporator and the phase change cold storage assembly, and the disassembly difficulty of the evaporator tube is relatively high, which further results in excessive maintenance difficulty of the phase change cold storage material. In contrast, in the embodiment of the present application, the phase-change cold storage assembly 500 is independently and detachably installed in the first box 100 in a modularized manner, so that the detachment difficulty of the phase-change cold storage assembly 500 can be greatly reduced.

The phase change cold storage assembly 500 may be mounted on the inner wall of the first box 100 by means of clamping, sticking, magnetic attraction, fastening, screwing, and the like, which is not limited in this embodiment of the present application.

For example, please continue to refer to fig. 3 and 4, fig. 3 is an exploded view of the refrigerated transport case of fig. 1, and fig. 4 is a partially enlarged view at X in fig. 3. The phase change cool storage assembly 500 may include a support 51 and a phase change cool storage unit 52. The support member 51 is detachably mounted on the inner wall of the first case 100, and the phase change cold storage unit 52 is disposed on the support member 51, so that the phase change cold storage unit 52 can be fixed in the first case 100 through the support member 51.

Phase change thermal storage unit 52 may include a housing and a phase change material contained within the housing. The housing may be a plate made of stainless steel, high density polyethylene, or high density polyvinyl chloride, for example. The phase change material contained within the housing may include at least one of an organic composite phase change material or an inorganic composite phase change material. For example, the phase change material contained within the housing may include nano-metals and carbon materials to further increase the thermal conductivity within the phase change thermal storage unit 52.

Specifically, the total thickness of phase change thermal storage unit 52 may be adjusted according to the storage time requirements of the transported article, such as, for example, phase change thermal storage unit 52 total thickness may be controlled between 25 millimeters and 30 millimeters. And, the phase change cold storage units 52 with different phase change temperatures can be selected according to the storage temperature requirement of the transported articles, for example, the phase change temperature of the phase change cold storage units 52 can be between-20 degrees and 20 degrees, the phase change latent heat of the phase change cold storage units 52 can be more than 220J/g, and the heat conductivity coefficient of the phase change cold storage units 52 can be more than 0.5W/(m.K).

In some embodiments, the support 51 may include a first support 511, the first support 511 being drawably disposed within the first case 100. The phase-change cool storage unit 52 includes a first phase-change cool storage unit 521, and the first phase-change cool storage unit 521 is disposed on the first support 511, so that the first support 511 can move out of the first case 100 to access the first phase-change cool storage unit 521.

It is also understood that when the refrigeration assembly 200 includes the evaporator 22, the evaporator 22 may be fixedly disposed on the inner wall of the first housing 100. The evaporator 22 is located at a side of the inner wall of the first case 100 adjacent to the first phase change cold storage unit 521, and the evaporator 22 is spaced apart from the first support 511 and the first phase change cold storage unit 521, respectively. Then, compared to the phase change cold storage material encapsulated on the refrigerant pipe wall of the evaporator 22, the phase change cold storage unit 52 of the embodiment of the present application can be more conveniently assembled and disassembled. In addition, since the first support 511 and the first phase-change cold storage unit 521 are disposed at intervals with the evaporator 22, interference between the first support 511 and/or the first phase-change cold storage unit 521 and the evaporator 22 during the drawing of the first support 511 can be avoided, so that the drawing of the first support 511 is smoother.

The first support 511 may have a mesh structure to facilitate heat exchange of the first phase change cold storage unit 521 with the inside of the first tank 100. For example, the first support 511 may be a mesh-leakage structure formed by interlacing a plurality of support bars. Of course, some reinforcing plates may be further disposed on the mesh structure to improve structural strength, which is not limited in the embodiments of the present application.

The support 51 may further include a second support 512, and the second support 512 is detachably connected to the inner wall of the first casing 100. The phase change cold storage unit 52 includes a second phase change cold storage unit 522, and the second phase change cold storage unit 522 is clamped to the second support 512. Further, the second phase change cold storage unit 522 is simply engaged with the second support 512, and the installation is completed. Meanwhile, when the specification of the second phase change cold storage unit 522 is changed, the second support 512 of a different type may also be replaced to be compatible with more types of second phase change cold storage units 522.

The second supporting member 512 may be detachably mounted on the inner wall of the first case 100 by means of clamping, hook and loop bonding, magnetic attraction, screwing, etc., which is not limited in this embodiment.

The second support member 512 may be fastened to the inner wall of the first casing 100 by a screw, so that a clamping groove is formed between the second support member 512 and the inner wall of the first casing 100, and the second phase change cold storage unit 522 is clamped into the clamping groove.

In some embodiments, the second support 512 has a bearing surface 5121 on a side thereof adjacent to the first support 511. The first support 511 is slidably supported on the supporting surface 5121, such that the first support 511 is disposed in the first housing 100 in a retractable manner. It can be appreciated that, compared with the structure of arranging other structures in the first box 100 to slidably mount the first supporting member 511, or the structure of forming the first supporting member 511 on the inner wall of the first box 100, the embodiment of the application can make the structure of the refrigerated transport case simpler and the manufacturing cost lower.

In some embodiments, second phase change thermal storage unit 522 is located in a different region inside first tank 100 than first phase change thermal storage unit 521 to make the temperatures throughout first tank 100 more uniform.

The first casing 100 may be a square casing including a top wall, a bottom wall, a front wall, a rear wall, a left wall, and a right wall, for example. The evaporator 22 may be mounted to a top wall of the first housing 100. The first phase change cold storage unit 521 may be located at a top wall of the first case 100. The second phase change cold storage units 522 may be multiple and are respectively located on the front wall, the rear wall, the left wall and the right wall of the first box 100, so that the temperature control effect inside the first box 100 can be ensured by placing the phase change cold storage units 52 on the four side walls and the top wall of the first box 100.

The first casing 100 may be made of a heat insulating material. For example, the first case 100 may include a nano heat insulating plate layer and a PU (polyurethane) layer, thereby reducing heat exchange efficiency between the inside of the first case 100 and the external environment to improve the refrigerating effect of the first case 100.

The nanometer heat insulating plate layer is made of nanometer heat insulating plate, namely a composite plate comprising an inorganic core material, a nanometer vacuum layer and a polymer composite film, and the nanometer heat insulating plate has high heat insulating performance and high flame retardant performance, and the heat conductivity coefficient of the nanometer heat insulating plate is less than 0.0025W/(m.K). The PU layer may be formed between two nano-insulation boards by foaming, so that the equivalent total thermal conductivity of the first box 100 is less than 0.004W/(m·k). Then, taking an example that the external environment temperature is 30 degrees and the internal temperature of the first box body 100 is 5 degrees, the internal-external temperature difference of the first box body 100 is 25 degrees, and the total diathermanous power of the first box body 100 is less than 25W.

The first box 100 may include a box body 11 and a box door 12, where the box door 12 is rotatably installed on the box body 11 to open or close the box body 11, and then the box door 12 is opened to access the transported articles in the first box 100. The door 12 may form a front wall, a rear wall, a left wall, or a right wall of the first case 100, which is not limited in the embodiment of the present application.

In combination with the first support member 511, when the door 12 is opened, the first support member 511 may be exposed at the access opening of the box body 11, so as to be pulled from the access opening of the box body 11 to the outside of the box body 11, thereby accessing the first phase-change cold storage unit 521, and further enabling a manager to replace the first phase-change cold storage unit 521 more conveniently.

Of course, the first casing 100 may further include a locking assembly 13, and the locking assembly 13 is mounted on the casing body 11 and/or the door 12 to lock the casing body 11 and the door 12 when the door 12 closes the casing body 11.

In some embodiments, the case body 11 is provided with a tray 14 to support the case body 11. Further, during the logistics transportation process, the forklift and other equipment can conveniently load or unload through the tray 14.

In some embodiments, the door 12 may be provided with pulleys 15 to support the door 12. Further, the door 12 may be supported by the pulley 15 when the door 12 is closed, to improve the reliability of the sealing of the door 12. And, in the process of the rotation of the door 12, the door 12 can be well supported by the pulley 15, so as to prevent the door 12 from falling off or bending downwards and enable the door 12 to rotate more smoothly.

In some embodiments, the refrigerated transport case further includes a second case 700. The second case 700 is mounted to an outer wall of the first case 100, and a portion of the photovoltaic module 300 and/or a portion of the refrigeration module 200 may be disposed in the second case 700.

With continued reference to fig. 5, fig. 5 is a schematic diagram of an overall connection of the refrigerated transport case of fig. 1. Illustratively, the refrigeration assembly 200 may include interconnected compressors such as a DC compressor 21, an evaporator 22, a condenser, and an expansion valve. Further, the direct-current compressor 21, the evaporator 22, the condenser and the expansion valve constitute a single refrigeration mechanism, and at this time, the evaporator 22 is disposed in the first casing 100, so that the first casing 100 can be refrigerated. The compressor, condenser and expansion valve may then be disposed within the second tank 700.

The photovoltaic module 300 may then comprise a photovoltaic panel 31. The second case 700 and the first case 100 are disposed side by side on the same side of the photovoltaic panel 31, and the orthographic projections of the planes of the second case 700 and the first case 100 on the photovoltaic panel 31 are at least partially located in the photovoltaic panel 31.

It is also to be understood simply that both the first and second housings 100, 700 are at least partially located directly under the photovoltaic panel 31. Thus, the embodiment of the present application can increase the area of the photovoltaic panel 31 compared to merely disposing the photovoltaic panel 31 directly above the first casing 100.

In some embodiments, the photovoltaic panel 31 may be fixedly connected to the first and second cases 100 and 700, respectively.

Alternatively, the photovoltaic panel 31 may be mounted to the first casing 100 and/or the second casing 700 by adjusting a bracket (not shown), so that the position state of the photovoltaic panel 31 relative to the first casing 100, such as the height, the inclination angle, etc. can be adjusted by adjusting the bracket, and the photovoltaic panel 31 can receive the irradiation of the sun at a more suitable angle, so as to improve the power generation efficiency of the photovoltaic panel 31.

In some embodiments, the photovoltaic assembly 300 may also include a photovoltaic controller 32 and an electrical energy storage component 33. The photovoltaic panel 31 is mounted to the first casing 100 to perform solar power generation. The photovoltaic controller 32 is electrically connected to the photovoltaic panel 31. The electrical energy storage component 33 is electrically connected to the photovoltaic controller 32 such that the photovoltaic controller 32 is capable of charging the electrical energy storage component 33, the electrical energy storage component 33 also being electrically connected to the refrigeration assembly 200, such as a compressor of the refrigeration assembly 200, to supply electrical energy to the refrigeration assembly 200.

It can be understood that, because the power generation amount per unit area of the photovoltaic panel 31 is smaller, the power generation voltage is also lower, if the photovoltaic controller 32 directly supplies power to the refrigeration assembly 200, the refrigeration assembly 200 can only select low power, and the voltage directly output by the photovoltaic panel 31 through the photovoltaic controller 32 is unstable, so that the refrigeration effect in the first box 100 is poor. In contrast, the embodiments of the present application may be relayed by an electric energy storage component 33, such as an aluminate battery, a phosphoric acid battery, etc., so that the electric energy storage component 33 can drive the higher power refrigeration assembly 200 with a larger and more stable voltage, thereby improving the refrigeration effect of the refrigerated transport case. Of course, in some other embodiments, the photovoltaic module 300 may also be powered by the photovoltaic controller 32 to power the refrigeration module 200, which is not limited in this embodiment.

The photovoltaic controller 32 may be an MPPT (Maximum Power Point Tracking ) solar controller so that the electrical energy converted by the photovoltaic panel 31 may be charged into the electrical energy storage member 33 in a more rational manner. The electric energy storage component 33 is charged, such as by an MPPT solar controller, in such a way that the MPPT tracks the maximum power, fast charge, balanced charge, float charge, etc.

In some embodiments, to facilitate monitoring the operating state of the electrical energy storage component 33, the photovoltaic assembly 300 may further include a first detection component 34, the first detection component 34 being electrically connected to the electrical energy storage component 33 for detecting at least one of the power, voltage, and current of the electrical energy storage component 33.

For example, the first detecting part 34 may be a voltage power meter capable of detecting the power, voltage, and current of the electric energy storage part 33 at the same time. Then, by detecting the state of the electric energy storage part 33, the state of charge of the electric energy storage part 33 by the photovoltaic controller 32, the state of power supply of the refrigeration module 200 by the electric energy storage part 33, and the like can be judged, so that the operation state of the photovoltaic module 300 can be known. Furthermore, the manager can determine whether the photovoltaic module 300 is operating normally through the operation state of the electric energy storage part 33 at any time, so that the manager can adjust and maintain the refrigerated transport case in time, thereby improving the low-temperature storage effect of the refrigerated transport case.

For example, the first detection component 34 may be configured to detect the input power to the electrical energy storage component 33, the power output to the refrigeration assembly 200, and the power output to other components powered by the electrical energy storage component 33. Further, the charging condition of the electric energy storage part 33 can be determined by the input power of the electric energy storage part 33, the working condition of the refrigeration assembly 200 can be detected by the power output to the refrigeration assembly 200 by the electric energy storage part 33, and the working condition of other parts can be monitored by the power output to other parts supplied by the electric energy storage part 33.

The power of the first detecting unit 34 detected by the other components supplied by the electric energy storage unit 33 may be directly measured by the first detecting unit 34, or may be obtained by detecting the total power output by the electric energy storage unit 33 and the power output by the electric energy storage unit 33 to the refrigeration unit 200, for example, when the electric energy storage unit 33 stops charging at night, the power output by the electric energy storage unit 33 to other components may be calculated by subtracting the power output by the electric energy storage unit 33 to the refrigeration unit 200 from the total power output by the electric energy storage unit 33.

It can be further understood that, because the voltage directly output by the photovoltaic panel 31 through the photovoltaic controller 32 is unstable, the first detecting component 34 in the embodiment of the present application may be electrically connected to the photovoltaic controller 32, and the electric energy storage component 33 may indirectly supply power to the first detecting component 34 through the photovoltaic controller 32, so that the first detecting component 34 operates more stably.

In some embodiments, the electrical energy storage component 33 is also electrically connected with a charging interface 35, the charging interface 35 being for connecting an external power source for charging.

The charging interface 35 may be a mains interface such as a 220V dc charging interface, and of course, the power and charging modes of the mains interface may be various according to the mains differentiation of different countries or regions, which is not limited in the embodiment of the present application.

Then, the electric energy storage component 33 can be charged by the combination of the charging interface 35 and the photovoltaic controller 32. For example, in case of a long period of overcast and rainy weather, the photovoltaic panel 31 may be charged with utility power in case of insufficient power generation. Still alternatively, the electric energy storage part 33 may be charged with the night discard electricity or the valley electricity through the charging interface 35.

When the photovoltaic module 300 includes the photovoltaic panel 31, the photovoltaic controller 32, the electric energy storage part 33, and the charging interface 35, it may be that the photovoltaic controller 32, the electric energy storage part 33, and the charging interface 35 are disposed in the second case 700. The second case 700 may be provided with a control window such as a first control window for controlling the photovoltaic module 300. Specifically, the control window 72 may be provided with an interactive device such as a touch screen, a control knob, a keyboard, etc. for the manager to perform man-machine interaction operation.

The second casing 700 may also be provided with a charging window 73 for an external power supply to be plugged into the charging interface 35 for charging.

Of course, the second case 700 may be further provided with a heat dissipation structure such as a heat dissipation window to dissipate heat.

With continued reference to fig. 6, fig. 6 is a schematic diagram of the connection of the main control system of the refrigerated transport case of fig. 1. The refrigerated transport case may also include a master control system 400. The master control system 400 is used to control the activation and deactivation of the refrigeration assembly 200.

In some embodiments, the master control system 400 is configured to adjust the operation modes of the refrigeration assembly 200 such that the start-up temperatures of the refrigeration assembly 200 in different operation modes are different, and such that the shut-down temperatures of the refrigeration assembly 200 in different operation modes are different. Wherein the start-up temperature is the temperature in the first tank 100 when the refrigeration assembly 200 needs to be started up. The shutdown temperature is the temperature within the first tank 100 at which the refrigeration assembly 200 needs to be shut down.

Further, the refrigerated transport case can flexibly control the start temperature and the shut-off temperature of the refrigeration assembly 200; then, even in the case that the power generation amount of the photovoltaic module 300 is small, the refrigerated transport case can more reasonably utilize the electric energy generated by the photovoltaic module 300, so that the inside of the first case 100 can maintain the proper temperature for a longer time, and further the refrigerating effect in the first case 100 is improved.

For example, the operating modes may include a first operating mode and a second operating mode.

If the operation mode of the refrigeration assembly 200 is the first operation mode, the start temperature is lower than or equal to the phase change temperature of the phase change cold storage assembly 500, and the close temperature is lower than the start temperature, so that the phase change cold storage assembly 500 absorbs or maintains cold energy.

If the operation mode of the refrigeration assembly 200 is the second operation mode, the start temperature is higher than the shutdown temperature, and the shutdown temperature is higher than or equal to the phase change temperature of the phase change cold storage assembly 500, so that the phase change cold storage assembly 500 releases cold energy.

It will be appreciated that the power consumption of the refrigeration assembly 200 may be different when the refrigeration temperature of the refrigeration assembly 200 within the first enclosure 100 is different in different modes of operation. Therefore, the refrigeration assembly 200 can be flexibly adjusted to different operation modes according to the power generation condition of the photovoltaic assembly 300. For example, the operating mode of the refrigeration assembly 200 can be adjusted to the first operating mode when the power generation of the photovoltaic assembly 300 is sufficient; in one aspect, the first mode of operation may maintain the temperature within the first enclosure 100 at a lower temperature to enhance the refrigeration effect on the transported items; on the other hand, the first operation mode may further store a certain amount of cold energy for standby through the phase change cold storage assembly 500. Or still, when the condition that the generating capacity of the photovoltaic module 300 is insufficient due to night or overcast weather or the like is met, the working mode of the refrigeration module 200 can be adjusted to the second working mode, and then the refrigeration module 200 can run with lower power consumption, and the refrigeration module 200 can release cold energy to perform auxiliary refrigeration through the phase-change cold storage module 500, so that the power consumption of the refrigeration module 200 is further reduced, and therefore the transported objects can be refrigerated for a longer time in the first box 100 under the condition that the generating capacity of the photovoltaic module 300 is fixed, and the refrigerating effect of the refrigerated transport case on the transported objects is improved.

With continued reference to fig. 7, fig. 7 is a schematic diagram of a main control system of the refrigerated transport case shown in fig. 6.

Accordingly, the temperature controller 42 may be electrically connected to the dc compressor 21, and thus the temperature controller 42 may control the start-up and shut-down of the refrigeration assembly 200 by starting up or shutting down the dc compressor 21.

In some embodiments, the photovoltaic controller 32 is electrically connected with the master control system 400, so that the photovoltaic controller 32 directly supplies power to the master control system 400, or the electric energy storage component 33 indirectly supplies power to the master control system 400 through the photovoltaic controller 32. It is understood that the voltage directly output by the photovoltaic panel 31 through the photovoltaic controller 32 is unstable, so that the operation of the main control system 400 can be more stable when the main control system 400 is indirectly powered by the electric energy storage unit 33 through the photovoltaic controller 32.

Alternatively, the photovoltaic controller 32 and the electric energy storage member 33 may be electrically connected to the main control system 400, respectively, so that the photovoltaic controller 32 and the electric energy storage member 33 may directly supply power to the main control system 400.

Of course, the photovoltaic controller 32 may not be electrically connected to the master control system 400, and the electric energy storage unit 33 may be electrically connected to the master control system 400, so that the electric energy storage unit 33 may supply power to the master control system 400 alone, which is not limited in the embodiment of the present application.

In some embodiments, the refrigerated transport case may further include a first identification device (not shown) for identifying a type of the transported object in the refrigerated transport case, so that the main control system 400 can adjust the operation mode of the refrigeration assembly 200 according to the type of the transported object, and/or so that the main control system 400 can configure the start-up temperature and/or the shut-down temperature of at least one operation mode according to the type of the transported object.

The above-mentioned master control system 400 can configure the start-up temperature and/or the shut-down temperature of at least one working mode according to the type of the transported article, and may be that the master control system 400 configures the start-up temperature and/or the shut-down temperature of the refrigeration assembly 200 in at least one working mode according to different types of transported articles. Such as configuring the start-up temperature of the second mode of operation based on the highest storage temperature of the transported item or configuring the shut-down temperature of the first mode of operation based on the lowest storage temperature of the transported item so that the transported item can be stored within a more suitable temperature interval.

Wherein the first recognition means may comprise first image capturing means.

Optionally, the first identifying device may also include a second communication module. For example, the second communication module is a first radio frequency receiving device, and the second communication module is used for communicating with the first radio frequency chip on the transported article to obtain the type information of the transported article, which is not limited in this embodiment of the present application.

In some embodiments, the refrigerated transport case may further include a second identification device (not shown) for identifying information of the phase change cold storage assembly 500. Master control system 400 is then capable of configuring the start-up temperature and/or the shut-down temperature of at least one mode of operation of the refrigeration assembly based on the information of phase change thermal storage unit 52.

For example, the information of the phase change thermal storage unit 52 may include a phase change temperature, and when the second identification means identifies that the type of the phase change thermal storage assembly 500 is changed to cause the phase change temperature to change, the master control system 400 may configure the start-up temperature and the shut-down temperature of at least one operation mode of the refrigeration assembly according to the phase change temperature of the phase change thermal storage assembly 500.

Wherein the second recognition means may comprise second image capturing means.

Alternatively, the second identifying device may also include a fourth communication module, such as a second rf receiving device, and the phase-change cold storage unit 52 may be provided with a fifth communication module, such as a second rf chip, so that the fourth communication module may identify the information of the phase-change cold storage assembly 500 through communication with the fifth communication module, which is not limited in this embodiment of the present application.

With continued reference to fig. 9, fig. 9 is another connection schematic diagram of the first communication module according to the embodiment of the present application. In some embodiments, the refrigerated transport case further includes a first communication module 600. The first communication module 600 is configured to perform wireless communication to transmit information, and at least one of the main control system 400 and the photovoltaic module 300 is electrically connected to the first communication module 600 to transmit information through the first communication module 600. Furthermore, the refrigerated transport case may communicate with a server or other intelligent terminal through the first communication module 600, so that a manager monitors the refrigerated transport case from the server or the intelligent terminal to know the working state of the refrigerated transport case.

Specifically, only the main control system 400 may be electrically connected to the first communication module 600, only the photovoltaic module 300 may be electrically connected to the first communication module 600, or both the main control system 400 and the photovoltaic module 300 may be electrically connected to the first communication module 600.
