天基激光器的排热方案研究

天基激光器运行过程中产生的大量废热需要排散,采用传统的热泵、单相或两相流体排热回路以及消耗性冷却剂等热控技术会使整个热管理系统质量、体积或功耗过大。以系统的轻量化和紧凑性为指标,对辐射冷却-冰蓄冷组合排热方案用于天基激光器的可行性进行了研究,结果表明,该方案能满足激光器废热排放要求,可大大减轻热控系统的质量和体积,说明它在未来天基激光器热管理中具有相当的应用潜力。

Schemes of heat rejection for a space-based laser

A great deal of waste heat from a space based laser must be rejected to outer space environment.Conventional thermal control systems such as heat pump,single phase or two phase pumped fluid loops or expendable water vaporizer are not very well suited for heat rejection requirements due to excessive mass,value and/or power consumption.A feasibility study on an integrated radiate cooling system with ice storage for the thermal management of a space based laser is assessed on the basis of compact and lightweight.The analytical results show that the integrated scheme can meet the waste heat rejection requirements and greatly reduce the total mass and volume of the thermal management system,and show its promising prospects in future space based lasers' thermal management systems.
