摘要
针对深海低温条件下海洋观测锂电池放电能力弱的情况,设计了一种深海耐压双层保温电池舱。利用ANSYS Workbench软件仿真分析了在不同保温层厚度下电池舱内温度分布情况以及电池舱内温度随时间的变化关系。仿真结果显示,随着保温层厚度的不断增加,电池舱内温度不断升高,温度达到稳定的时间也在不断增加,并且发现选用真空保温层2 mm,聚氨酯保温层5 mm的组合保温方式最有效。
Aiming at the weak discharge ability of ocean observation lithium batteries under deep-sea low temperature condition,a deep-sea pressure resistant double-layer insulation battery compartment was designed.ANSYS Workbench software was used to simulate and analyze the temperature distribution in the battery compartment with different insulation layer thickness and the relationship between the temperature change in the battery compartment with time.The simulation results show that as the thickness of the insulation layer increases,the temperature in the battery compartment continues to increase,and the time for the temperature to stabilize is also increasing.It’s found that the combination method of 2 mm vacuum insulation layer and 5 mm polyurethane insulation layer is the most effective.
