The charging or driving of alternative energy vehicles can generate significant heat, which, if not addressed promptly, can greatly impact the safety and reliability of the components and even lead to potential fires. Organic silicon thermal conductive potting adhesive with its excellent thermal conductivity and protective properties has emerged as an ideal choice for auxiliary materials in managing the temperature of alternative energy power batteries.
The application advantages of silicone thermal conductivity potting adhesive are as follows:
01 Ensure battery safety
The number of battery cells installed in alternative energy vehicle batteries is currently directly proportional to their endurance. However, increasing the number of battery cells without expanding the available space will inevitably result in a reduced distance between the cells. When alternative energy vehicles are fully charged and discharged, they generate a significant amount of heat. If this accumulated heat is not dissipated and cooled promptly, it can easily lead to accidents such as battery short circuits and fires.
The organic silicon thermal conductive potting adhesive has a low viscosity and excellent leveling performance, allowing it to evenly fill the small gaps between battery cells. This not only facilitates the quick transfer of heat to the heat dissipation area or external air but also ensures the utmost safety of the battery system. Simultaneously, it maximizes the number of battery cells, effectively guaranteeing high endurance for alternative energy vehicle power battery systems while achieving lightweight design.
02 Rapid cooling
Currently, the cooling methods for alternative energy vehicles primarily include direct cooling, air/water mixed cooling, low-temperature radiator cooling, and direct air cooling. These methods rely on silicone thermal conductive potting adhesive as a medium to efficiently transfer heat from the battery core to the cooling area.
03 Impact protection
Scratches and collisions are inevitable for alternative energy vehicles while driving, which can lead to power battery pack failure if left unprotected. To worsen it, these incidents may even result in fire or explosion.
The organic silicon thermal conductive potting adhesive possesses the inherent polymer structure and cross-linking characteristics of organic silicon material, along with exceptional elasticity, strain properties, and chemical stability. It effectively alleviates stress caused by impact and vibration within a wide range of temperature and humidity conditions. In case of an impact, it provides elastic buffering and protective functions for the power battery pack, thereby enhancing the overall safety of the vehicle.
04 Short-circuit blocking
The internal short circuit of the battery is a crucial factor that affects the ignition of alternative energy vehicles, as mentioned earlier. Organic silicon thermal conductive potting adhesive offers stable dielectric insulation, excellent thermal conductivity, and high flame retardancy. In case of a single battery cell experiencing a short circuit or self-explosion due to overcharging, this adhesive can act as a barrier to prevent chain reactions and safeguard the surrounding battery cells' safety. Consequently, it enhances the overall safety of the battery module.
The use of organic silicon thermal conductive potting adhesive material is currently widespread in alternative energy electric vehicles, ensuring the safety and reliability of theirs. All in all, organic silicon plays an indispensable role in this regard.
