基于ZBO存储的低温储箱漏热分析

Heat leakage analysis of cryogenic tank based on ZBO storage

由于低温液体的存储温度很低,造成周围环境的热量漏入贮箱内部,导致低温液体的蒸发和贮箱内部压力升高。为了解决上述问题,采用被动绝热与主动制冷相结合的零蒸发无损存储(ZBO)方案,通过分析计算进入低温贮箱内的热量,包括通过储箱体、颈管及连接管路进入储箱的热量,为进一步减小漏热量及优化ZBO存储性能提供理论依据。

Storage temperature of cryogenic liquid leads to ambient heat leak into the tank, cryogenic liquid evaporation and pressure increase in the tank. For solving above-mentioned problem, passive insulation of active cooling technology with achieve zero boil off storage was used, and the heat leakage entering the tank was analyzed and calcuated, including those through tank body,neck pipe and connecting pipe.
