Description

Technical Field

[0001] This utility model relates to the field of battery heat conduction technology, and in particular to a convenient battery heat conduction structure. Background Technology

[0002] A battery is a cup, tank, or other container or composite container containing an electrolyte solution and metal electrodes to generate an electric current. It is a device that converts chemical energy into electrical energy and has positive and negative electrodes. With the advancement of technology, the term "battery" now generally refers to small devices that can generate electrical energy, such as solar cells. The main performance parameters of a battery are electromotive force, capacity, specific energy, and resistance.

[0003] Battery thermal conduction is the process by which heat is transferred inside the battery through collisions of microscopic particles. The principle is based on the thermal motion of molecules. Molecules in high-temperature regions have high kinetic energy and transfer energy to molecules in low-temperature regions through collisions, allowing heat to diffuse from the heat-generating parts to the low-temperature parts. Its function is to maintain the battery temperature balance, avoid local overheating that could lead to performance degradation, shortened lifespan, or even thermal runaway; and ensure that the battery operates within a suitable temperature range, ensuring charging and discharging efficiency and safety. It is the core component of the battery thermal management system.

[0004] Traditional battery heat conduction suffers from unstable heat conduction efficiency and insufficient adhesion durability. At the same time, the air duct heat dissipation lacks dynamic adjustment capability, making it difficult to cope with temperature changes of the battery under different operating conditions and environments, resulting in limited overall thermal management effectiveness.

[0005] Therefore, it is necessary to provide a convenient battery heat conduction structure to solve the above-mentioned technical problems. Utility Model Content

[0026] Compared with related technologies, the convenient battery heat conduction structure provided by this utility model has the following advantages: To improve the thermal conductivity of the portable battery thermal conduction structure, a thermal conductive component 17 consisting of a thin aluminum sheet 171, a substrate 172, and a heat sink 173 is installed between each battery pack 16. Utilizing the high thermal conductivity of the thermal conductive component 17, the thermal conduction efficiency and effectiveness are improved.

[0027] Please refer to the following: Figures 6-7 , Figure 6 A schematic diagram of the second embodiment of the convenient battery heat conduction structure provided by this utility model; Figure 7 Provided for this utility model Figure 6 The enlarged view at point C shows a convenient battery heat conduction structure based on the first embodiment of this application. The second embodiment of this application proposes another convenient battery heat conduction structure. The second embodiment is merely a preferred embodiment of the first embodiment, and its implementation will not affect the independent implementation of the first embodiment.

[0028] Specifically, the difference in the convenient battery heat conduction structure provided in the second embodiment of this application is that, please refer to... Figure 6The thermally conductive component 17 includes an aluminum alloy material 1701, a thermally conductive silicone layer 1702, and a graphene coating 1703, wherein the thermally conductive silicone layer 1702 is installed between the aluminum alloy material 1701 and the graphene coating 1703.

When the thermal conductive component 17 is subjected to a temperature close to the phase change point, the paraffin pellets 19 absorb heat and change from solid to liquid. The latent heat of phase change reduces the instantaneous thermal pressure of the aluminum sheet. When the temperature drops, the material solidifies and releases heat, which is conducted out by the heat sink 173 and the air duct 20. This design reduces the peak battery temperature under extreme conditions, slows down the rate of temperature rise, and avoids thermal shock damage to the battery pack 16.
