摘　　要：在分析平流层飞艇载荷舱传热特性和高空环境特性的基础上,提出了采用基于开放式二氧化碳制冷和冷板相结合的平流层飞艇载荷舱电子设备冷却方案。所提出的方案能避免单纯采用冷板散热所面临的制冷量不足的问题。同时,通过建立理论计算模型并结合VC++编程软件,获得了飞艇上升过程中所需要携带的二氧化碳的量的理论值,并分析了气瓶内二氧化碳的状态变化及造成制冷量损失的因素。结果表明:通过计算所得的理论量能够满足飞艇上升过程的制冷要求,且在低储存温度、大管径、低背压的情况下制冷量损失较小。该研究结果为平流层飞艇载荷舱电子设备的冷却提供技术参考。After analyzing the heat transfer of the stratospheric airship gondola and the environment at the high altitude,we propose an open carbon dioxide refrigeration system combined with cold plate.The proposed approach can avoid the insufficient cooling caused by the only use cold plate.Meanwhile,by establishing the thermal simulation model and using VC++software,the required mass of CO2 is obtained.Additionally,we analyse the state of CO 2 in gas tanks and the factors affecting the loss of cooling capacity during rising process.Results indicate that the calculated mass of CO2 meets the cooling requirements for the airship rising process,and in the case of low temperature,large pipe diameter and low backpressure,the cooling capacity loss is smaller.Our research provides technical references for the cooling of electronic devices in the stratospheric airship gondola.
