What are the applications of vacuum sealing units in the new energy industry

source：m.tywdhb.com | Release time：2025年11月10日

Vacuum sealing units have a wide range of applications in the new energy industry, mainly including the following aspects:
1. New energy vehicle battery pack: The vacuum sealing unit can be used for sealing and protecting the battery pack. It can vacuum seal the battery module, ensuring a tight fit between the gel and the battery components, effectively preventing electrolyte leakage, improving the waterproof level of the battery pack, reaching IP68 level, while enhancing the heat dissipation performance of the battery pack, improving the safety and stability of the battery. A new energy vehicle company's actual test shows that after using a vacuum sealing machine, the failure rate of battery connector sealing has decreased from 8% to 0.5%.
2. New energy vehicle motor: In the drive motor of new energy vehicles, the vacuum sealing unit can seal the stator coil, fill the coil gap, improve insulation level and heat dissipation efficiency, and prevent copper wire wear caused by high-speed vibration. At the same time, it can also be used for fixing the rotor magnet, by vacuum gluing to prevent the magnet from falling off, enhancing the reliability of the motor at high temperatures and high speeds.
3. Motor controller: The IGBT module in the motor controller needs to work in harsh environments. The vacuum sealing unit can use a three chamber full vacuum injection molding process to prepare, feed, and inject materials in a vacuum environment, effectively preventing the mixing of air or water vapor during sealing, ensuring that the IGBT chip is effectively isolated from harsh external environments, guaranteeing its stable operation, and can withstand a wide temperature range of -40 ℃ to 150 ℃.
4. Photovoltaic field: Vacuum sealing units can be used for packaging photovoltaic modules, sealing and protecting solar cells, improving their impact resistance and waterproof performance, and extending the service life of photovoltaic modules. In addition, vacuum sealing can also be used to improve the insulation and heat dissipation of electronic components in devices such as photovoltaic inverters.
5. Wind turbine: For the stator winding of the wind turbine, the vacuum sealing unit can be encapsulated as a whole to resist corrosion from harsh environments such as humidity and salt spray, and extend the service life of the equipment. At the same time, vacuum sealing can also improve the insulation performance and mechanical strength of wind turbine motors, ensuring their stable operation under high-speed and high wind conditions.
