Fig. 1 is a schematic structural diagram of the packaging structure for the energy storage power supply provided in this embodiment after removing part of the packaging material, as shown in fig. 1, this embodiment provides a packaging structure for the energy storage power supply, where the packaging structure for the energy storage power supply is a square bag body or box structure, and an accommodating cavity 2 for accommodating the energy storage power supply is provided in the packaging structure for the energy storage power supply. When the energy storage power supply is not used or needs to be transported, the energy storage power supply can be placed in the accommodating cavity 2 of the packaging structure, so that the energy storage power supply is stored and protected, and the energy storage power supply is convenient to carry and transport. Specifically, the package structure for the energy storage power supply is formed by enclosing the package material 1. It should be noted that, the packing material 1 may be an integral packing material, and may be formed into a closed packing structure after being folded and butted, or the packing material 1 may also be set into independent packing material monomers, and the packing structure is usually formed by sequentially butt-jointing six packing material monomers end to end.
Further, as shown in fig. 2, the package 1 has a multi-layered structure along the thickness direction thereof, specifically, the package 1 includes at least a first cloth layer 11, a first heat insulating layer 12, a phase-change heat absorbing layer 13, and a second cloth layer 14, which are sequentially stacked from outside to inside, that is, the first heat insulating layer 12 and the phase-change heat absorbing layer 13 are wrapped inside by the first cloth layer 11 and the second cloth layer 14. Wherein, from outside to inside is relative to the packaging structure, "outside" refers to the outside of the packaging structure and "inside" refers to the inside of the packaging structure.
When the temperature of the external environment is high, the external heat enters the packaging material 1, firstly, the external heat sequentially passes through the first cloth layer 11 and the first heat insulation layer 12, the first heat insulation layer 12 can isolate part of the heat, the residual heat passes through the phase-change heat absorption layer 13, and after reaching the phase-change temperature point, the phase-change heat absorption layer 13 absorbs most of the residual heat through state transition of itself, so that the heat entering the packaging material 1 is greatly reduced, and the influence on an energy storage power supply is reduced. Through setting up first insulating layer 12 and phase transition heat-absorbing layer 13, can reach thermal-insulated endothermic purpose again, avoided a large amount of heat to get into and hold behind the chamber 2 and lead to energy storage power supply to take place the thermal runaway risk, guaranteed energy storage power supply's performance and life. When the external environment temperature is lower, the first heat insulation layer 12 can also prevent the internal heat from being dissipated, so that the heat insulation effect is achieved.
Preferably, the first cloth layer 11 and/or the second cloth layer 14 are/is woven cloth, which is convenient to obtain materials, has lower cost and enables the quality of the packing material 1 to be lighter.
Further, the first insulation layer 12 is aerogel or insulation cotton, wherein the insulation cotton is selected from insulation cotton with low thermal conductivity. Compared with the traditional materials, the aerogel and the heat insulation cotton can achieve better heat insulation effect with lighter weight and smaller volume. Through the thickness of design aerogel or heat preservation cotton for external heat is through the heat-insulated back of aerogel or heat preservation cotton, and the heat that transmits to phase transition heat-absorbing layer 13 can reach its phase transition temperature, thereby makes phase transition heat-absorbing layer 13 can absorb heat energy storage, reduces the heat that gets into in holding chamber 2 by a wide margin, avoids energy storage power supply to appear thermal runaway risk. Meanwhile, the thickness of the packing material 1 can be reduced by matching the aerogel or the heat preservation cotton with the phase-change heat absorption layer 13. When external environment temperature is lower, aerogel or heat preservation cotton can also prevent that inside heat from dispelling away, plays the heat preservation effect. In other embodiments, other heat insulating materials may be used for the first heat insulating layer 12, as long as the heat insulating effect can be achieved, and the present utility model is not limited thereto.
Further, as shown in fig. 2, the phase-change heat-absorbing layer 13 includes an encapsulation shell 131 and a phase-change material 132, and the phase-change material 132 is filled in a cavity of the encapsulation shell 131. The encapsulation case 131 is made of plastic or artificial leather, and the encapsulation case 131 is used to encapsulate the phase change material 132 therein. Phase change material 132 is a highly efficient energy storage material that stores heat through its own phase transition after reaching the phase change temperature point, providing temperature control and heat absorption effects. That is, phase change material 132 undergoes a change in morphology of the substance during the phase change, typically a solid state transition to a molten state.
It will be appreciated that phase change material 132 absorbs heat and changes from a solid state to a molten state, and if phase change material 132 is configured in a larger sheet form, phase change material 132 tends to sink and accumulate by gravity and tends to leak when it changes to a molten state.
In order to solve the above problem, referring to fig. 2 and 3, a plurality of chambers which are not communicated with each other are formed in the package case 131, and are arranged in an array, and each chamber contains a phase change material 132. In this embodiment, the phase change material 132 in the plurality of chambers and the plurality of chambers are arranged in a square array of a plurality of rows and a plurality of columns, and the specific number of the phase change material is not limited herein, and the phase change material can be flexibly arranged according to actual requirements. By individually sealing and fixing the plurality of smaller phase change materials 132, the occurrence of the phenomenon of sinking and stacking and leakage when the phase change materials 132 are converted into a molten state can be prevented, and the lightweight design is satisfied. Meanwhile, the connection positions between two adjacent rows of chambers and the connection positions between two adjacent columns of chambers can be conveniently folded so as to meet the transportation performance.
Further, phase change material 132 is in a flake or powder-like structure when in a solid state wire, and is flexible to use. The size of the sheet phase change material 132 is matched with the size of each cavity, and according to different use environments, the phase change material 132 with different quality can be filled in each cavity so as to meet different heat absorption use time.
Preferably, phase change material 132 is a hydrated salt or paraffin wax. Wherein, the hydrated salt is powdered, and paraffin is the slice, and hydrated salt and paraffin all have better phase transition heat absorption effect, and cooperation above-mentioned first insulating layer 12 uses, can reach thermal-insulated purpose of absorbing heat again, and well with heat isolation outside, avoided the thermal runaway risk, and can reduce the thickness of packing material 1 by a wide margin. In other embodiments, the phase change material 132 may be replaced by other types of phase change materials, so long as the phase change heat absorbing effect can be achieved, and the method is not limited herein.
Preferably, as shown in fig. 2, the second insulating layer 15 is further stacked on the inner side of the second cloth layer 14, or the second insulating layer 15 is further stacked between the phase change heat absorbing layer 13 and the second cloth layer 14, and fig. 2 only shows the first case. When external environment temperature is higher, external heat can get into first insulating layer 12, phase transition heat absorption layer 13 and second insulating layer 15 in proper order to reach thermal-insulated, the purpose that absorbs heat and insulate against heat again, can be nearly thoroughly with heat isolation outside, reduce by a wide margin and get into the heat that holds in the chamber 2, further avoided thermal runaway risk. When the external environment temperature is lower, the second heat insulation layer 15 and the first heat insulation layer 12 are matched for use, so that internal heat can be further prevented from being dissipated, and the heat preservation effect is improved.
Preferably, the second insulation layer 15 is aerogel or insulation cotton. Compared with the traditional material, the aerogel or the heat-insulating cotton can achieve better heat-resistant effect by lighter weight and smaller volume, thereby greatly reducing the heat entering the accommodating cavity 2 and further avoiding the thermal runaway risk of the energy storage power supply. When external environment temperature is lower, aerogel or heat preservation cotton can also prevent that inside heat from dispelling away, uses with first insulating layer 12 cooperation, can further improve the heat preservation effect. In other embodiments, other heat insulating materials may be used for the second heat insulating layer 15, as long as the heat insulating effect can be achieved, and the present utility model is not limited thereto.
Further, a temperature sensor (not shown) is disposed in the accommodating cavity 2, and the temperature sensor is used for detecting an ambient temperature inside the accommodating cavity 2, so that a user can conveniently judge whether the temperature condition in the accommodating cavity 2 affects the energy storage power supply according to the detected temperature. If the temperature in the accommodating cavity 2 is too high, the thickness of the first heat insulation layer 12, the phase-change heat absorption layer 13 or the second heat insulation layer 15 in the packing material 1 can be adaptively increased to meet the heat insulation and absorption requirements of the packing material 1, and if the temperature in the accommodating cavity 2 is too low, the thickness of the first heat insulation layer 12 or the second heat insulation layer 15 in the packing material 1 can be adaptively increased to meet the heat insulation requirements, and the use experience of a user is improved. The temperature sensor is in the prior art, and specific connection modes and working principles thereof are not described herein.
