Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of logistics distribution, and particularly relates to a unit distribution box and a logistics distribution vehicle with the same. BACKGROUND

[0002] With the improvement of living standards, there are more and more application scenarios that need to provide cold or heat. If a refrigerating unit is set in all application scenarios, the cost is high and the energy consumption is also high.

[0003] For example, cold chain logistics generally refers to a system engineering that keeps cold storage frozen food in a specified low-temperature environment in each link from production, storage and transportation to sales to consumption, so as to ensure food quality and reduce food loss. The traditional cold chain transport vehicle supplies power to the refrigerating unit through gasoline or battery pack, and the refrigerating unit works to supply cold to the cold storage box. The refrigerating unit needs to work throughout the entire transport section, which consumes a lot of energy and has low utilization rate.

[0004] In order to save energy and protect the environment, an energy storage component is loaded on the cold chain transport vehicle to store cold at the starting point. During the entire transport process, the cold storage unit supplies cold to the cold storage box, thereby reducing energy consumption. However, the existing energy storage component has a long cold storage time, for example, between 10 and 13 hours. The energy storage component and the storage room are not completely insulated, and this process will affect the temperature in the storage room, especially the goods in the storage room near the energy storage component will be frozen.

[0005] Therefore, it is necessary to provide an improved unit distribution box and a logistics distribution vehicle with the same to solve the above technical problems. SUMMARY

[0012] Further, the energy storage devices adjacent in the first direction have gaps extending in the first direction, and the energy storage assembly further comprises partition plates arranged between the side walls forming the energy storage chamber on both sides of the energy storage assembly in the first direction, two adjacent partition plates on the same side have two rows of gaps, and the partition plates on the two sides are arranged in a staggered manner in the direction from the energy storage chamber to the storage chamber, and the gaps form the energy storage passage.

[0013] Further, the energy storage chamber is located below the storage chamber.

[0014] Further, the energy supply assembly comprises a temperature sensor arranged in the storage chamber, an energy supply air duct communicating between the energy storage chamber and the storage chamber, and an energy supply fan driving air circulation between the storage chamber and the energy storage chamber, and the temperature sensor and the energy supply fan are in communication connection with the controller.

[0015] Further, the energy storage chamber is located below the storage chamber, the energy supply air duct comprises a first air duct extending in the up-down direction and communicating between the energy storage chamber and the storage chamber, and a return air outlet arranged on the return air temperature insulation plate at the bottom of the storage chamber and communicating with the energy storage chamber, the air outlet of the first air duct leading to the storage chamber is located at the top of the storage chamber, and the energy supply fan is arranged in the energy storage chamber, or the energy supply fan is arranged in the storage chamber, or the energy supply fan is arranged in the first air duct.

During the energy storage process, it will not have an excessive impact on the temperature of the storage chamber, thus avoiding the product from freezing. Attached Figure Description

DETAILED DESCRIPTION

[0038] The present application will be described in detail below with reference to the specific embodiments shown in the drawings. However, these embodiments do not limit the present application, and the structural, method, or functional changes made by those of ordinary skill in the art based on these embodiments are included in the protection scope of the present application.

[0039] In various diagrams of the present application, certain dimensions of structures or parts are exaggerated relative to other structures or parts for ease of illustration, and thus only serve to illustrate the basic structure of the subject matter of the present application.

[0040] For ease of description, the lower and upper are defined according to the orientation of the energy storage device in actual use.

[0041] Please refer to Figures 1-16 The unit distribution box 100 of the preferred embodiment of the present application is shown, which includes a box body 1 and a door body 2, and the door body 2 is provided with a door lock 21. The box body 1 and the door body 2 are both made of thermal insulation materials, such as vacuum insulation panels or foamed thermal insulation panels.

[0042] The box body 1 is provided with a storage chamber 3, an energy storage chamber 4 adjacent to the storage chamber 3, an energy storage assembly in the energy storage chamber 4, an energy supply assembly 8 for transmitting the energy of the energy storage assembly to the storage chamber 3, and a controller 10. The controller 10 is communicatively connected with other elements to control the working state thereof.

[0043] Compared with the prior art of arranging the energy storage assembly in the storage chamber 3, the storage chamber 3 and the energy storage chamber 4 of the present application are arranged adjacent to each other, and are separated by a return air temperature insulation panel 31, and the energy storage assembly indirectly provides cold or heat to the storage chamber 3 through the energy supply assembly 8. On the one hand, the energy storage chamber 4 is arranged adjacent to the storage chamber 3, the path of the energy supply assembly 8 is short, and the arrangement is relatively simple. On the other hand, loading goods in the storage chamber 3 and pre-cooling the goods can be performed simultaneously with the cold storage of the energy storage assembly, thereby saving time, and since the two compartments are independent, the opening of the storage chamber 3 will not cause the cold leakage of the energy storage assembly. Furthermore, during the energy storage process, the energy storage assembly has a small influence on the temperature in the storage chamber 3, and will not freeze the goods. During the energy supply process, the temperature in the storage chamber 3 is highly controllable, and the temperature fluctuation is small.

[0044] The positional relationship between the storage chamber 3 and the energy storage chamber 4 is arranged according to actual conditions. Preferably, the energy storage chamber 4 is located below the storage chamber 3, and the center of gravity of the unit distribution box 100 is located below, so that the unit distribution box 100 is not prone to falling during hoisting, especially when the box is empty.

[0045] The energy storage assembly includes a plurality of rows of energy storage devices 5 and energy storage channels for the flow of energy carriers to provide energy to the energy storage devices 5. The energy carriers are collectively referred to as all fluids that can bring heat or cold to the energy storage devices 5.

[0046] Please see Figures 6-16 As shown, the energy storage device 5 includes a shell 51, an inner tube 56 passing through the shell 51 and having a flow channel, a closed energy storage cavity 52 formed by the shell 51 and the inner tube 56 for storing energy storage materials, and a heat-conducting plate 57 located in the energy storage cavity 52; the heat-conducting plate 57 is in contact with at least one of the shell 51 or the inner tube 56 to improve the heat exchange rate.

[0047] The shape of the outer casing 51 is not limited and can be adapted to meet needs or installation space requirements. For example... Figure 6 In the embodiment shown, the outer shell 51 includes an outer tube 53 and end caps 54 that close both ends of the outer tube 53. The end caps 54 can be any structure that closes both ends of the outer tube 53, and the end caps 54 and the outer tube 53 can be separately or integrally disposed.

[0048] The cross-sectional shape of the outer tube 53 is circular, polygonal, or any other arbitrary shape, including but not limited to triangles, squares, hexagons, trapezoids, etc.

[0049] The end cap 54 is provided with a through hole 543 for the inner tube 56 to pass through. The through hole 543 of the end cap 54 is fitted onto the inner tube 56, and the connection between the end cap 54 and the inner tube 56 is sealed by welding or other means. This process is convenient for manufacturing. At the same time, the end cap 54 and / or the outer tube 53 are provided with an injection port 541 for injecting energy storage material into the energy storage chamber 52. After the energy storage material is injected, the injection port 541 is sealed by a sealing element 542.

[0050] The energy storage device 5 also includes an energy storage material located within the energy storage chamber 52. The energy storage material is preferably a phase change material, which can store or release a large amount of energy during a phase change process. The amount of energy storage material added is such that, when the energy storage material is in a liquid state, its volume does not exceed 80% of the volume of the energy storage chamber 52, ensuring that the energy storage device 5 will not deform or break due to increased volume during a phase change.

[0051] The cross-sectional shape of the inner tube 56 can be circular, polygonal, or any other arbitrary shape. The cross-sectional shapes of the inner tube 56 and the outer tube 53 can be the same, making their relative positions readily apparent. Alternatively, the cross-sectional shapes of the inner tube 56 and the outer tube 53 can be different, increasing the selection space and allowing for the optimal shape combination based on actual conditions.

[0052] In a preferred embodiment, both ends of the inner tube 56 are exposed outward from the end cap 54, facilitating welding of the inner tube 56 to the outer shell 51. In other embodiments, such as Figure 9As shown, a sleeve extending inwardly can also be provided on the end cover 54, and the inner tube 56 is connected with the sleeve, and the inner tube 56 is located inside the outer shell 51. Of course, the sleeve can also extend outwardly from the end cover 54.

[0053] The heat-conducting sheet 57 can expand the heat transfer area, thereby improving the heat exchange speed. Therefore, by adjusting the structure, arrangement density, etc. of the heat-conducting sheet 57, the heat exchange speed in the energy storage cavity 52 can be changed. The relative position of the inner tube 56 and the outer tube 53, the specific structure of the heat-conducting sheet 57, and the arrangement mode thereof will be described in detail below.

[0054] The heat-conducting sheet 57 includes a heat transfer sheet 571 in contact with the inner tube 56 and the outer shell 51. The heat transfer sheet 571 not only supports and fixes the inner tube 56, but also enables the inner tube 56 and the outer shell 51 to quickly exchange heat, so that the inner tube 56 and the outer shell 51 respectively exchange heat with the energy storage material in the energy storage cavity 52 from the inner and outer sides, thereby improving the heat exchange efficiency.

[0055] In a specific embodiment, the heat transfer sheet 571 extends outwardly from the inner tube 56. "Extending outwardly from the inside" means that the heat transfer sheet 571 has a tendency to extend outwardly from the inside, including but not limited to extending radially outwardly along the inner tube 56.

[0056] Further, the heat transfer sheet 571 includes an inner connecting portion connected with the inner tube 56 and / or an outer connecting portion connected with the outer shell 51, thereby improving the connection strength and heat transfer performance of the heat transfer sheet 571 with the inner tube 56 and the outer tube 53.

[0057] The heat transfer sheet 571 can be in a sheet shape, an arc shape, a spiral shape, etc. A sheet shape is preferred, which facilitates manufacturing, especially when the inner tube 56, the heat transfer sheet 571, and the outer shell 51 are integrally formed, thereby greatly reducing the process difficulty. After being cut along an axial direction perpendicular to the inner tube 56, the cross section of the heat transfer sheet 571 is in a rectangular shape, a triangular shape, a trapezoidal shape, an arc shape, etc.

[0058] Taking the sheet shape as an example, the thickness of the heat transfer sheet 571 is not less than 1.5 mm, and is preferably between 1.5 mm and 2 mm. The heat transfer sheet 571 has sufficient strength to support and fix the inner tube 56, and the heat transfer sheet 571 with the thickness has small thermal resistance, which can effectively reduce the heat attenuation of the heat transfer sheet 571, thereby ensuring the effective heat transfer between the outer tube 53 and the inner tube 56.

[0059] As can be seen from the above, the more the heat transfer sheets 571, the faster the heat exchange speed of the entire energy storage device 5. The number of the heat transfer sheets 571 is calculated according to the extension direction of the heat transfer sheets 571 relative to the inner tube 56, i.e. the heat transfer sheets 571 extending in different directions from the inner tube 56 are two different heat transfer sheets 571; and is not directly calculated according to the connection points of the heat transfer sheets 571.

[0060] The inventor has found that when the energy storage device 5 contains at least two heat transfer sheets 571, the heat transfer sheets 571 divide the energy storage cavity 52 into at least two sub-energy storage cavities 521. In use, when the energy storage material in the sub-energy storage cavities 521 changes in volume due to phase change, the shell 51 surrounding the sub-energy storage cavities will be deformed or broken, affecting the use and appearance; or the heat transfer sheets 571 surrounding the sub-energy storage cavities will be deformed or broken, affecting the heat exchange speed.

[0061] To solve the technical problem, the energy storage device 5 further comprises a communication channel 55 communicating at least two sub-energy storage cavities 521. By the communication channel 55, each sub-energy storage cavity 521 is connected in communication, and when the energy storage material changes in volume due to phase change, such as from liquid to solid, the liquid energy storage material can flow in the adjacent sub-energy storage cavities 521 through the communication channel 55, releasing the pressure of the single sub-energy storage space, preventing the energy storage device 5 from being deformed or broken.

[0062] Specifically, the communication channel 55 is located between the heat transfer sheet 571 and the inner tube 56, or the communication channel 55 is located between the heat transfer sheet 571 and the shell 2; or the communication channel 55 penetrates the heat transfer sheet 571, i.e. the communication channel 55 is arranged inside the heat transfer sheet 571.

[0063] In a preferred embodiment, the heat transfer sheet 571 extends along the axial direction of the inner tube 56, the communication channel 55 is located between at least one end of the heat transfer sheet 571 in the axial direction of the inner tube 56 and the inner tube 56; and / or the communication channel 55 is located between at least one end of the heat transfer sheet 571 in the axial direction of the inner tube 56 and the shell 51. Such a design greatly reduces the processing difficulty, especially in the energy storage device 5 formed by the inner tube 56, the heat transfer sheet 571 and the outer tube 53, which can be formed, and then part of the heat transfer sheet 571 at at least one end of the heat transfer sheet 571 in the axial direction of the inner tube 56 can be removed to form the communication channel 55, which is simple and feasible.

[0064] Further, the heat-conducting sheet 57 further comprises at least one heat-dissipating sheet 572 located in the sub-energy storage cavity 521, and the heat-dissipating sheet 572 can further improve the heat exchange speed. The heat-dissipating sheet 572 is connected with the inner tube 56, and a gap is formed between the heat-dissipating sheet 572 and the outer shell 51; or the heat-dissipating sheet 572 is connected with the outer shell 51, and a gap is formed between the heat-dissipating sheet 572 and the inner tube 31.

[0065] The heat-dissipating sheet 572 is different from the heat-conducting sheet 571 in structure only in that the thickness of the heat-dissipating sheet 572 is smaller than that of the heat-conducting sheet 571, and the heat-dissipating sheet 572 does not occupy too much of the energy storage cavity 52 while ensuring the improvement of the heat exchange speed, and at the same time, the weight and cost can be reduced.

[0066] Preferably, the heat-dissipating sheet 572 is provided with an auxiliary communication channel 55' at a position corresponding to the communication channel 55, so as to ensure the smooth flow of the energy storage material. The "position corresponding to the communication channel 55" refers to the position on the heat-dissipating sheet 572 mapped by the communication channel 55 along the circumference of the inner tube 56, and the fluid medium can quickly pass through the adjacent communication channel 55 and auxiliary communication channel 55', so as to improve the flow speed.

[0067] Specifically, along the axial direction of the inner tube 56, at least one end of the heat-conducting sheet 571 and the heat-dissipating sheet 572 is located between the inner side of the outer shell 51 and the outer shell 51, and a gap is formed therebetween, which constitutes the communication channel 55, and the energy storage material in different sub-energy storage cavities 521 flows at the gap.

[0068] In a specific embodiment, the inner tube 56 extends along the axial direction of the outer tube 53, and both ends of the inner tube 56 are exposed outwardly from the end cover 54, and both ends of the heat-conducting sheet 571 along the radial direction of the inner tube 56 are in contact with the inner tube 56 and the outer tube 53, respectively; and a gap is formed between the end of the heat-conducting sheet 571 and the heat-dissipating sheet 572 along the axial direction of the inner tube 56 and the end cover 54, and the gap constitutes the communication channel 55.

[0069] The inventor has also found in research that the phase change speed of the energy storage material is related to the speed of obtaining cold or heat, and the setting position of the inner tube 56 in the outer tube 53, the structure of the heat-conducting sheet 571 and the setting mode thereof, and / or the structure of the heat-dissipating sheet 572 and the setting mode thereof all have an influence on the speed of obtaining cold or heat by the energy storage material, and the faster the energy storage material obtains cold or heat, the faster the phase change occurs.

[0070] The heat transfer sheet 571 and the heat dissipation sheet 572 divide the energy storage cavity 52 into several small non-closed cavities; if the energy storage material at the outlet of the cavity has a volume change phase change before the energy storage material inside, for example, the energy storage material at the outlet of the cavity changes from liquid to solid, and the energy storage material inside the cavity changes from liquid to solid, which will cause the shell 51, the inner tube 56 or the heat conducting sheet 57 surrounding the cavity to deform or burst. On the contrary, if the energy storage material inside the cavity has a volume change phase change before the energy storage material at the outlet, that is, the phase change speed of the energy storage material in the energy storage cavity decreases from the inside to the outlet of the cavity, when the volume change phase change occurs inside, the liquid or gaseous energy storage material flows outward, which can avoid the deformation or rupture of the energy storage device 5; therefore, how to control the change direction of the phase change speed in at least part of the energy storage cavity 52 is crucial.

[0071] In the present application, the structure and arrangement of the heat conducting sheet 57 in part of the energy storage cavity 52 meet at least one of the following conditions: the length of the heat conducting sheet 57 decreases along the circumference of the inner tube 56, the arrangement density of the heat conducting sheet 57 decreases along the circumference of the inner tube 56, and the thickness of the heat conducting sheet 57 decreases along the circumference of the inner tube 56. In the above decreasing direction, the heat conducting sheet 57 provides less heat or cold to the energy storage liquid in the energy storage cavity, and the phase change speed of the energy storage liquid decreases, which can avoid the deformation or rupture of the energy storage device 5.

[0072] The above-mentioned "part of the energy storage cavity" is a part of the energy storage cavity 52, and in the above-mentioned embodiment in which the heat conducting sheet 57 includes the heat transfer sheet 571 and the heat dissipation sheet 572, the above-mentioned "part of the energy storage cavity" is a sub-energy storage cavity 521 between two adjacent heat transfer sheets 571. The above-mentioned "decrease" refers to a decreasing trend in unit volume, which can be continuous decrease, or discontinuous decrease such as equal difference decrease or stepwise decrease.

[0073] Specifically, the heat-conducting sheet 57 extends from the inner tube 56 to a direction away from the inner tube 56, and the heat-conducting sheet 57 comprises at least two heat transfer sheets 571 in contact with the inner tube 56 and the outer shell 51, an included angle between at least two adjacent heat transfer sheets 571 ranges from 90° to 180°, a length of the heat-dissipating sheet 572 between the two heat transfer sheets 571 decreases along a circumferential direction of the inner tube 56, and / or a setting density of the heat-dissipating sheet 572 decreases along the circumferential direction of the inner tube 56, so that a heat transfer area of the heat-dissipating sheet 572 decreases from one heat transfer sheet 571 to another heat transfer sheet 571, and the energy storage liquid in the sub-energy storage cavity 521 gradually changes phase in the decreasing direction; and / or a thickness of the heat-dissipating sheet 572 decreases along the circumferential direction of the inner tube 56, so that a heat attenuation of the heat-dissipating sheet 572 increases along the decreasing direction, and the energy storage liquid in the sub-energy storage cavity 521 gradually changes phase in the decreasing direction.

[0074] In the first embodiment, referring to Figures 6-10 As shown in the figure, the inner tube 56 is concentrically arranged with the outer tube 53, that is, a central axis of the inner tube 56 coincides with a central axis of the outer tube 53, so that the entire energy storage device 5 is relatively balanced, easy to manufacture and has a long service life. At this time, at least one of the structure or the setting density of the heat-conducting sheet 57 is adjusted to control the phase change sequence of the energy storage material in different regions.

[0075] Specifically, referring to Figures 6-10 As shown in the figure, the setting density of the heat-dissipating sheet 572 decreases and / or the length of the heat-dissipating sheet 572 decreases from one heat transfer sheet 571 to another heat transfer sheet 571 arranged adjacent to the one heat transfer sheet 571. Therefore, the sum of the heat transfer areas of the heat-dissipating sheets 572 in the region with a large setting density or a long length of the heat-dissipating sheets 572 is large, the region with a large heat transfer area changes phase first, and the region with a small heat transfer area changes phase later; so that the energy storage material gradually changes phase along the arrow direction shown in the figure, avoiding deformation or rupture of the energy storage device 5. Figure 8

[0076] Specifically, along the circumferential direction of the inner tube 56, the length of the heat-dissipating sheet 572 is the same, and the setting density between adjacent heat-conducting sheets 57 decreases, that is, the included angle between adjacent heat-conducting sheets 57 increases. The smaller the included angle, the smaller the cavity between the two adjacent heat-conducting sheets 57, and the faster the energy storage material in the cavity obtains cold or heat and changes phase. The included angle between the heat-conducting sheets 57 includes the included angle between the adjacent heat transfer sheets 571 and the heat-dissipating sheet 572, and the included angle between the two adjacent heat-dissipating sheets 572.

[0077] ​Or, along the circumference of the inner tube 56, the included angle between adjacent heat-conducting fins 57 is the same, and the length of the heat-dissipating fin 572 decreases. The longer the length of the heat-dissipating fin 572, the greater the heat transfer area, and the faster the adjacent energy storage material obtains cold or heat, and the phase change occurs earlier. Please refer to Figure 7 As shown, the longer the length La of the heat-dissipating fin 572, the shorter the distance Lb of the heat-dissipating fin 572 from the outer shell 51; for example, Lb1 is less than Lb2.

[0078] Preferably, please refer to Figures 7-9 As shown, along the circumference of the inner tube 56, the included angle between adjacent heat-conducting fins 57 increases, and the length of the heat-dissipating fin 572 decreases, and the greater the difference in the speed of obtaining cold or heat in different areas, which is more conducive to the step-by-step phase change.

[0079] In addition, along the circumference of the inner tube 56, the thickness of the heat-conducting fin 57 gradually decreases, the greater the thickness of the heat-conducting fin, the smaller the heat attenuation, the smaller the thermal resistance, and the faster the heat transfer speed, which can also achieve the above technical effects.

[0080] Further, based on the above specific embodiments, the outer tube 53 has a first end and a second end located on opposite sides of its axis, the heat-conducting fin 57 includes two heat transfer fins 571 extending to the first end and the second end respectively, and the two heat transfer fins 571 divide the energy storage cavity 52 into two symmetrically arranged sub-energy storage cavities 521; the heat-dissipating fin 572 located in the two sub-energy storage cavities 521 is symmetrically arranged relative to the heat transfer fin 571. Therefore, from the first end to the second end, the phase change speed of the energy storage liquid in the two sub-energy storage cavities 52 is consistent, that is, the phase change speed of the energy storage liquid on both sides of the two heat transfer fins 571 is basically consistent, which can avoid deformation or breakage of the heat transfer fin 571.

[0081] Please refer to Figure 8 As shown, the energy storage material at each point in the energy storage cavity 52 obtains cold or heat from the inner tube 56, the heat-conducting fin 57, and the outer tube 53 adjacent to it, Figure 8 The arrows in the figure show the order of the size of the energy obtained by different points. During use, when the energy storage device 5 is installed, the side with a larger density of the heat-conducting fin 57 is placed below, and the side with a smaller density of the heat-conducting fin 57 is placed above, so that the liquid or gaseous energy storage material flows upward, avoiding pipe expansion.

[0082] For example, when the energy storage device 5 is charged with cold from the inner tube 56, the closer the area to the inner tube 56, the faster the energy storage material in each two heat-conducting sheets 57 obtains cold, and the earlier the crystallization occurs; the greater the density of the heat-conducting sheets 57, the faster the energy storage material obtains heat or cold, and the earlier the crystallization occurs; thus, the energy storage material gradually changes phase in the direction indicated by the arrow, and the gas and liquid can effectively flow upwards, effectively avoiding tube expansion.

[0083] In addition, please refer to Figures 11-16 As shown in the figure, the inner tube 56 is eccentrically arranged with the outer tube 53, that is, the central axis of the inner tube 56 deviates from the central axis of the outer tube 53.

[0084] Specifically, the outer tube 53 has a first end and a second end located on opposite sides of its central axis, and after the inner tube 56 is offset to the first end, the energy storage material located on the side of the first end exchanges heat with the inner tube 56 faster than the energy storage material located on the side of the second end. If the inner tube 56 is connected to the cold charging unit, the energy storage material located on the side of the first end will change phase first due to its faster cooling speed, while the energy storage material located on the side of the second end will change phase later due to its slower cooling speed. This can effectively control the gradual phase change of the energy storage material in the energy storage cavity 52 from the first end to the second end, avoiding deformation or cracking of the energy storage device 5 caused by disordered phase change direction.

[0085] In the second embodiment, please refer to Figure 11 or Figure 12 As shown in the figure, the offset distance between the central axis of the inner tube 56 and the central axis of the outer tube 53 is not greater than a threshold L1, and the heat-conducting sheet 57 extends outward from the inner tube 56 along the radial direction of the inner tube 56.

[0086] In a specific embodiment, as shown in Figure 11 The included angle between adjacent heat-conducting sheets 57 along the circumferential direction of the inner tube 56 is equal, and the length of the heat-conducting sheet 571 is the same. On the basis of the eccentric arrangement of the inner tube 56, it is also conducive to the gradual phase change of the energy storage material.

[0087] The heat-conducting sheet 57 includes two heat-conducting sheets 571, and the two heat-conducting sheets 571 divide the energy storage cavity 52 into two sub-energy storage cavities 521; the heat-conducting sheet 57 also includes a plurality of heat-dissipating sheets 572 connected to the inner tube 56 and located in the sub-energy storage cavities 521, and the heat-dissipating sheet 572 has a gap with the outer shell 51, and in each sub-energy storage cavity 521, a plurality of heat-dissipating sheets 572 are uniformly arranged along the circumferential direction of the inner tube 56.

[0088] Preferably, the heat radiating fins 572 located in the two sub-accumulating cavities 521 are symmetrically arranged relative to the heat conducting fins 571.

[0089] As shown in Figure 12 , the heat radiating fins 572 are arranged in the same way as in the embodiment shown in Figures 7-9 , which will not be described here again. On the basis of the eccentric arrangement of the inner tube 56 and the reduced length or arrangement density of the heat radiating fins 572, the phase change of the accumulating material gradually occurs more favorably.

[0090] In the third type of embodiment, please refer to Figures 13-16 , the inner tube 56 is offset relative to the center axis of the outer tube 53 towards the first end, and the offset distance is not less than a threshold value L2; at this time, the offset distance of the inner tube 56 is large, and the cold or heat it carries is much larger than that of the heat conducting fins 57, so the heat or cold obtained by the accumulating material from the inner tube 56, the heat conducting fins 57 and the outer tube 53 has a decreasing trend as a whole from the first end to the second end; so that the accumulating material gradually changes phase in one direction, avoiding phase change from multiple directions to the middle, which causes the accumulating device 5 to deform or crack.

[0091] Specifically, as shown in Figure 13 , when the offset distance is between the threshold value L2 and the threshold value L3, L2 is less than L3; the heat radiating fins all extend outward from the inner tube 56.

[0092] In an embodiment, the two heat conducting fins 571 extending towards the first end and the second end respectively divide the accumulating cavity 52 into two symmetrically arranged sub-accumulating cavities 521, and a plurality of heat radiating fins 572 are in contact with the inner tube 56 and have a gap between the heat radiating fins 572 and the outer shell 51; in the sub-accumulating space 111, along the circumferential direction of the inner tube 56 from the first end to the second end, the length and / or arrangement density of the heat radiating fins 572 increases.

[0093] Specifically, along the circumferential direction of the inner tube 56 from the first end to the second end, the length of the heat radiating fins 572 is the same, and the included angle between adjacent heat conducting fins 57 decreases. Or, along the circumferential direction of the inner tube 56 from the first end to the second end, the included angle between adjacent heat conducting fins 57 is the same, and the length of the heat conducting fins 57 increases. Preferably, along the circumferential direction of the inner tube 56 from the first end to the second end, the included angle between adjacent heat conducting fins 57 decreases, and the length of the heat conducting fins 57 increases.

[0094] In the above several specific embodiments, due to the large offset distance of the inner tube 56, the heat or cold obtained by the energy storage material from the inner tube 56, the heat-conducting sheet 57 and the outer tube 53 has a decreasing trend from the first end to the second end, so that the energy storage material gradually changes phase in one direction, avoiding the phase change from multiple directions to the middle, which causes the energy storage device 5 to deform or burst; at the same time, the energy storage speed of the entire energy storage device 5 is faster.

[0095] Further, the heat sinks 572 located in the two sub-energy storage cavities 521 are symmetrically arranged relative to the heat-conducting sheet 571.

[0096] When the offset distance is not less than a threshold L3, L2 is less than L3, the distance between the inner tube 56 and the outer tube 53 is closer, and if the heat sink 572 extends towards the offset side, the distance between the heat sink 572 and the outer tube 53 is closer, which is not conducive to the flow of liquid or gaseous energy storage material; therefore, the heat sink 572 extends from the first end of the inner tube 56 and away from the direction of the inner tube 56.

[0097] Specifically, please refer to Figures 14-16 As shown in the figure, from the first end to the second end, the length of the heat sink 572 increases, but the heat or cold obtained by the energy storage material from the inner tube 56, the heat-conducting sheet 57 and the outer tube 53 as a whole has a decreasing trend.

[0098] In specific use, the first end of the energy storage cavity 52 is placed below, and the second end of the energy storage cavity 52 is placed above, so that the liquid or gaseous energy storage material flows upwards, avoiding pipe expansion.

[0099] Further, the outer wall of the shell 51 has an identification indicating the first end and / or the second end; or in other words, the identification indicates the above-mentioned decreasing direction, and when the energy storage device 5 is installed, the identification plays a prompting role, so as to avoid placing the side with small heat transfer density downward and causing burst phenomenon.

[0100] In addition, based on all the above embodiments, the inner tube 56, the heat-conducting sheet 57 and the outer tube 53 are integrally formed or arranged, and the heat transfer effect is far superior to the post-assembly scheme. Preferably, aluminum or aluminum alloy material, light in quality and fast in heat transfer speed.

[0101] Specific processing process is that the inner tube 56, the heat transfer sheet 571 and the outer tube 53 are integrally formed; the communication channel 55 is formed at the edge of the heat conduction sheet 57 along the axial direction of the inner tube 56, for example, part of the heat conduction sheet 57 is removed, so that the heat conduction sheet 57 is located in the outer tube 53; the end cover 54 is welded with the outer shell 51; the energy storage material is injected into the energy storage cavity 52 from the injection port 541, and then the injection port 541 is sealed.

[0102] The energy storage devices 5 are arranged in a honeycomb shape, a cross shape or a thousand island shape.

[0103] The energy storage channels are communicated with the energy storage devices 5 row by row along the direction from the energy storage chamber 4 to the storage chamber 3, and the inlet 6a of the energy storage channel is located at the energy storage device 5 farthest from the storage chamber 3, and the outlet 6b of the energy storage channel is located at the energy storage device 5 closest to the storage chamber 3. The energy carrier enters the energy storage channel from the inlet 6a, and then flows out from the outlet 6b after heat exchange with the energy storage device 5, so that the energy storage devices 5 far from the storage chamber 3 obtain heat or cold before the energy storage devices 5 close to the storage chamber 3, and the temperature in the storage chamber 3 is less affected during the energy storage process, so that the product can be prevented from being damaged by freezing.

[0104] In one embodiment, the energy storage channel is arranged in the energy storage device 5, that is, the energy storage channel is surrounded by the energy storage device 5 with energy storage material, and the heat loss is small.

[0105] Specifically, the energy storage assembly further comprises a connecting pipe 6 with a flow passage, the connecting pipe 6 comprises an intra-row connecting pipe 61 connecting the flow channels of the energy storage devices 5 in each row in series, and an inter-row connecting pipe 62 connecting the flow channels of the adjacent energy storage devices 5 in two adjacent rows along the direction from the energy storage chamber to the storage chamber; the flow channels and the flow passage jointly constitute the energy storage channel. In this embodiment, the energy storage devices 5 in each row are connected in series, and then connected with the energy storage devices 5 in the adjacent row in series, the energy carrier enters the energy storage channel from the inlet 6a, and then flows out from the outlet 6b after passing through all the energy storage devices 5 row by row, so that the flow of the energy carrier is large, and the circulating flow speed is fast under the same power source.

[0106] Alternatively, the energy storage assembly further comprises a connecting pipe 6 with a flow passage, the connecting pipe 6 comprises an inter-row connecting pipe 62 connecting the flow channels of the corresponding two energy storage devices 5 in two adjacent rows; the flow channels and the flow passage jointly constitute the energy storage channel. In this embodiment, the corresponding energy storage devices in different rows are connected in series, and the energy storage devices 5 in the same row are connected in parallel, the energy carrier is divided, which is suitable for larger power source and cold source, but the uniformity of the energy obtained by all the energy carriers is relatively high, and the partial energy storage devices 5 are prevented from being too cold.

[0107] In the above two embodiments, the energy carrier flows in the flow channel of the energy storage device 5, and therefore the energy storage device 5 is made of a material with good corrosion resistance and good thermal conductivity.

[0108] Alternatively, the energy storage device 5 comprises a flow channel, and the energy storage assembly further comprises a connecting pipe 6 with a flow passage, the connecting pipe 6 comprises an intra-row connecting pipe 61 penetrating into the flow channel of each row of energy storage devices 5, and an inter-row connecting pipe 62 connecting the intra-row connecting pipes 61 of two adjacent energy storage devices 5 in two adjacent rows in the direction from the energy storage chamber to the storage chamber, and the flow passage constitutes the energy storage channel.

[0109] Preferably, the outer wall of the connecting pipe 6 is in close contact with the inner wall of the flow channel. Here, "close contact" means no gap, and the two are gapless within the assembly error range; therefore, the heat or heat reference transfer direction is: liquid in the connecting pipe 6 → the connecting pipe 6 → the inner wall of the flow channel → the cold storage liquid in the energy storage device 5; the cold or heat is transferred between liquid-solid, solid-solid, and solid-liquid, with less heat loss, ensuring fast and effective heat transfer and reducing heat transfer loss. For example, the connecting pipe 6 is in interference fit with the flow channel, which can be achieved by pipe expansion process.

[0110] In another type of implementation, the energy storage channel is arranged adjacent to the energy storage device 5.

[0111] Specifically, the adjacent energy storage devices 5 have a gap 63 extending in the first direction, and the gap 63 constitutes the energy storage channel. The energy storage assembly further comprises a partition plate between the side wall of the energy storage chamber 4 and the two sides of the energy storage assembly in the first direction, and two gaps 63 are arranged between two adjacent partition plates, and the partition plates on the two sides are arranged in a staggered manner in the direction from the energy storage chamber 4 to the storage chamber 3. The energy carrier passes through the gap 63 and exchanges heat with the energy storage material in the energy storage device 5.

[0112] For example, in the direction from the energy storage chamber 4 to the storage chamber 3, the partition plate on one side is located between the first and second gaps 63 and between the third and fourth gaps 63; the partition plate on the other side is located between the second and third gaps 63; and the energy carrier passes through the first, second, third, and fourth gaps 63 in sequence.

[0113] In a preferred embodiment, the energy storage chamber is located below the storage chamber 3, and the energy storage devices 5 at the bottom obtain heat or cold before the energy storage devices 5 above them, and according to the principle of cold air sinking and hot air rising, the temperature influence on the storage chamber 3 during the energy storage process is minimized.

[0114] And the energy carrying agent enters the energy storage assembly from the inlet 6a, exchanges heat with the energy storage device 5 from bottom to top, and then flows out of the energy storage assembly through the outlet 6b, so that the energy storage device 5 in the lower row obtains heat or cold before the energy storage device 5 above it, and the energy storage device 5 in the lower row can provide heat or cold to the energy storage device 5 above it through heat radiation or contact heat transfer, ensuring that the lower energy storage material changes phase before the upper energy storage material, and avoiding the phenomenon of deformation or rupture of the energy storage device 5.

[0115] The energy supply assembly 8 is used to transmit the energy accumulated by the energy storage assembly to the storage chamber 3 to preserve the products in it.

[0117] Preferably, the energy supply assembly 8 further includes a temperature sensor (not shown) in the storage chamber 3 and in communication connection with the controller 10, and according to the temperature in the storage chamber 3, the working state of the energy supply fan 82 is controlled to provide hot air or cold air in the storage chamber 3 to maintain the temperature in a small range. The working state of the energy supply fan 82 includes but is not limited to the fan speed, the duty cycle of the fan start-stop, etc.

[0118] When the energy storage chamber 4 is below the storage chamber 3, the energy supply air duct 81 includes a first air duct 811 extending in the up-down direction and communicating the energy storage chamber and the storage chamber 3, and a return air opening 812 provided on the return air temperature separation plate 31 at the bottom of the storage chamber 3 and communicating with the energy storage chamber 4. The air outlet of the first air duct 811 leading to the storage chamber 3 is located at the top of the storage chamber 3, that is, the first air duct 81 communicates to the top of the storage chamber 3. Most of the products transported in the unit distribution box 100 need to be refrigerated or frozen. The cold air is blown into the storage chamber 3 from the top of the storage chamber 3 through the first air duct 811, which conforms to the principle of cold air sinking, and when there are few products that need to be refrigerated / frozen, the top of the storage chamber 3 is idle, and the cold air will not be directly blown to the products, avoiding local freezing of the products.

[0119] The first air duct 811 and at least part of the return air opening 812 are respectively arranged on opposite sides of the storage chamber 3, which is beneficial to air circulation.

[0120] Further, the return air temperature insulation plate 311 comprises a top plate 311, a bottom plate 312, and a flow cavity 313 between the top plate 311 and the bottom plate 312, the return air port 812 penetrates the top plate 311, the bottom plate 312, and communicates with the flow cavity 313, and the top plate 311 is provided with an auxiliary return air port 812' near one side of the first air duct 811. The air in the storage chamber 3 can also pass through the auxiliary return air port 812', the flow cavity 313, and the return air port 812 into the cold storage chamber 4, and the air in the storage chamber 3 can also pass through the return air port 812, the flow cavity 313, and the auxiliary return air port 812' to return to the storage chamber 3, which can effectively avoid the existence of dead angles in the storage chamber 3 and cause uneven air temperature distribution in the storage chamber 3.

[0121] Preferably, the top plate 311 or the bottom plate 312 is provided with a reinforcing rib 314 with a flow hole 315, which can enhance the strength of the return air temperature insulation plate 31.

Of course, the energy supply fan 82 is located in the storage chamber 3, or the energy supply fan 82 is located in the first air duct 811, which can also drive air circulation.

[0123] The unit distribution box 100 further comprises a refrigeration unit 9, and the refrigeration unit 9 comprises a compressor, a condenser connected with the compressor, a throttling element connected with the condenser, an inlet of the energy storage channel connected with the throttling element, and an outlet of the energy storage channel connected with the compressor; and the energy carrier is a refrigerant.

[0124] Alternatively, the unit distribution box 100 further comprises a refrigeration unit 9 and an energy storage fan, the refrigeration unit comprises a compressor, a condenser, a throttling element, and an evaporator connected to form a circulation loop, and the evaporator and the energy storage fan are located on the circulation loop communicating with the energy storage channel, and at this time the energy carrier is cold air passing through the evaporator.

[0125] The refrigeration unit 9 provides cold or heat to the energy storage assembly, so that cold storage can be completed anywhere with power supply without setting up a cold charging site, and the refrigeration unit 9 can also provide cold to the storage chamber 3 to precool the products located therein.

[0126] Preferably, the unit distribution box 100 further comprises a compressor compartment 91 located below the energy storage chamber 4, the walls constituting the compressor compartment 91 are provided with heat dissipation holes 92, and the refrigeration unit 9 is located in the compressor compartment 91. On the one hand, the compressor compartment 91 is spaced from the storage box 4 by the energy storage chamber 4, so that the heat released by the refrigeration unit 9 during operation does not directly affect the temperature of the storage box 2; on the other hand, the center of gravity of the entire unit distribution box 100 is lowered, which can prevent the unit distribution box 100 from falling during lifting.

[0127] The unit distribution box 100 also comprises a heating assembly 7 for providing heat to the storage chamber 3 to compensate for the temperature of the storage chamber 3 or to keep the goods warm in cold regions.

[0128] The heating assembly 7 comprises a heater 71 and a heating fan 72 in the storage chamber 3, and of course, when both the power fan 82 and the heating fan 72 are arranged in the storage chamber 3, they can also share the same fan.
