Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model.
Referring to fig. 1 to 3, the present utility model provides an automatically cooled battery case, comprising: a bottom wall 11; a side wall 12 connected to the peripheral side of the bottom wall 11, the side wall 12 and the bottom wall 11 enclosing a case body 10 for accommodating the battery module 15; wherein, the inside of the bottom wall 11 and the inside of the side wall 12 are formed with a hollow cavity 13, the hollow cavity 13 is embedded with a phase change material 14, and the phase change material 14 generates a phase change reaction in the hollow cavity 13 according to the temperature of the battery module 15; the bottom wall 11 and the side wall 12 are both provided with a heat conducting pad 20, and the heat conducting pad 20 is used for propping against the outer surface of the battery module 15.
The phase change material 14 has the ability to change its physical state over a range of temperatures. Taking solid-liquid phase change materials as an example, when heated to a melting temperature, a phase change from solid to liquid is produced, and during melting, the phase change material 14 absorbs and stores a significant amount of heat; when the phase change material 14 cools, the stored heat is dissipated to the environment within a certain temperature range, and the phase change is reversed from liquid to solid. In both phase-change processes, the stored or released energy is referred to as phase-change heat. When the physical state changes, the temperature of the phase change material 14 itself remains almost unchanged until the phase change is completed, forming a wide temperature plateau, and the heat absorbed or released is quite large although the temperature is unchanged.
According to the battery box capable of automatically cooling, the hollow cavity 13 is formed in the bottom wall 11 and the side wall 12, so that the overall weight can be reduced, the phase change material 14 capable of absorbing a large amount of heat and discharging the heat to the outside air is embedded in the hollow cavity 13, namely, a cooling system is integrated in the battery box, so that the battery box has the dual functions of installing the battery module 15 and cooling the battery module 15, a liquid cooling plate and a water pump are not required to be additionally arranged, the number and the variety of parts are reduced, the installation process is simplified, the system reliability is greatly improved, the production cost is reduced, the occupied space is also reduced, and the space utilization is improved, so that the energy density can be increased; importantly, in the scheme, the heat conducting pad 20 has certain elasticity and good heat conductivity, can fill the gaps between the battery module 15 and the bottom wall 11 and the side wall 12 respectively, and when a large amount of heat is generated in the high-rate charge-discharge process of the battery module 15, the heat can be quickly, uniformly and fully transferred to the phase change material 14 through the heat conducting pad 20, so that the problems of uneven heat transfer and lower heat transfer efficiency caused by the gaps are avoided, the heat dissipation efficiency is improved, and the temperature of each surface of the battery box body is kept consistent; moreover, it can be understood that, after the battery pack is used for a long time, the cell 151 of the battery module 15 is inevitably expanded, which may cause interference between the case body 10 and the battery module 15, and because the thermal pad 20 has elasticity, the thermal pad 20 needs to be extruded when the cell 151 expands, the thermal pad 20 can play a buffering role between the case body 10 and the battery module 15, so as to avoid deformation of the case body 10 and interference between the case body 10 and the battery module 15, and can play a role in inhibiting expansion of the cell 151.
Specifically, in this embodiment, the heat conducting pad 20 is a heat conducting silica gel pad, and has the advantages of easy function implementation, simple structure and low production cost. Of course, in some other embodiments, the thermal pad 20 may also be, but is not limited to, a thermally conductive structural adhesive or a thermally conductive AB adhesive, without limitation.
Further, in the present embodiment, the phase change material 14 is a solid-liquid phase change material. Specifically, when the temperatures of the bottom wall 11 and the side walls 12 reach the phase transition temperature of the phase change material 14, the cooling function of the battery module 15 is achieved by a mechanism that the phase change material 14 absorbs a large amount of heat from a solid state to a liquid state in the hollow cavity 13, and when the battery cell 151 stops or is charged and discharged at a small rate, the temperature is reduced, the phase change material 14 is solidified from the liquid state to the solid state in the hollow cavity 13, and the stored heat is released to the outside air.
Therefore, compared with the liquid-gas phase change material, the solid-liquid phase change material can quickly absorb heat from solid state to liquid state when the battery pack heats, has higher volume energy storage density, can absorb more heat in the phase change process from solid state to liquid, has high heat dissipation efficiency, has small expansion and shrinkage property when the solid-liquid phase change material changes phase, can not deform due to the phase change of the phase change material 14 even after long-time use, can avoid the swelling phenomenon of the battery pack, and eliminates potential safety hazards.
Preferably, in the present embodiment, a graphite structure or an EG material structure may be further disposed in the phase change material 14 to improve the heat conductivity of the phase change material 14.
Preferably, the hollow cavity 13 extends along the length direction of the case body 10, so that the volume of the hollow cavity 13 can be ensured to accommodate a larger volume of the phase change material 14, thereby improving heat dissipation efficiency. Preferably, at least one reinforcing rib 131 is disposed in the hollow cavity 13, and the at least one reinforcing rib 131 divides the hollow cavity 13 into a plurality of sub-hollow cavities. By this arrangement, the structural strength of the side wall 12 and the bottom wall 11 can be improved, thereby prolonging the service life and the use safety of the battery case.
In order to prevent the phase change material 14 from leaking, it is preferable that the bottom wall 11 and the side wall 12 are integrally formed, that is, the phase change material 14 does not leak from the junction between the bottom plate and the side wall 12, so that the hollow cavity 13 can be ensured to have excellent sealing performance, and potential safety hazards are eliminated.
