石墨烯熱管電池熱管理系統 2023/07/11

簡介 Introductions

電池操作合適溫度為20~45^oC，過高或過低，會大幅影響電池的充放電性能和壽命。而石墨烯熱管比傳統熱管的最大熱傳量增加50%，熱傳導係數增加80%，在高熱傳的散熱能力，維持電池性能及壽命。

The suitable temperature for battery operation is 20~45^oC. If it is too high or too low, it will greatly affect the charging and discharging performance and life of the battery. The graphene heat pipe is 150% better than the traditional heat pipe in terms of maximum heat transfer and 80% better in thermal conductivity. It maintains battery performance and longevity in terms of high heat transfer heat dissipation capability.
