摘要
为研究多夹层大板生物隔离舱,以解决目前方舱围护大板、集成预制存在的诸多问题,同时探究其传热性能,基于结构断桥、大板复合、模块预设,研究了一种高强度且满足国军标的方舱用铝合金泡沫气凝胶大板,舱体按40GP标准集装箱规格设计,计算出围护体系传热系数。通过Fluent仿真模拟,对标设定外部环境温度极值范围为-45~55℃,采用自然对流换热和体积力的瞬态求解方式,分别观测舱内最高和最低温度变化趋势。在-45和55℃条件下,最高、最低温分别约为9000和7200 s后逐渐趋向一致,10800 s观测点均达至热稳定状态。该方舱隔热效果明显,实现了集舱体保温隔热、功能预制集成为一体的超长生物隔离舱设计,针对特殊医疗装备领域方舱的深化研究具有指导意义。
In order to study the multi sandwich large panel biological isolation cabin,so as to solve the problems existing in the current square cabin enclosure panels and integrated prefabrication,and explore its heat transfer performance.Based on the structural break bridge,the large panel composite and the module preset,a large aluminum alloy foam aerogel gel panel with high strength which satisfied the national military standard was designed.The cabin was designed according to the 40GP standard container specification and we calculated the heat transfer coefficient of the envelope system.Through Fluent simulation,the extreme range of external ambient temperature was set as-45~55℃.The transient solution of natural convection heat transfer and volume force was adopted to observe the variation trend of maximum and minimum temperature in the cabin.Under the conditions of-45 and 55℃,the highest and lowest temperatures gradually tended to be consistent after about 9000 and 7200 s,and the observation points reached thermal stability at 10800 s.The cabin had obvious thermal insulation effect,and we realized the design of ultralong biological isolation cabin integrating thermal insulation with functional prefabrication.It had guiding significance for the further research of cabin in the field of special medical equipment.
