摘要
为改善航天器热控系统的控温可靠性,基于石蜡感温相变体积发生变化的特性,构建了自适应控温冷板,并给出了自适应控温冷板内的石蜡和复位弹簧的设计模型。在此基础上,为了开展自适应控温冷板的性能分析研究,建立了采用自适应控温冷板的航天器单相流体回路热控系统,并基于集总参数法构建该单相流体回路热控系统的热网络模型。结果表明,所设计的自适应控温冷板在不同的热载荷条件下具备可靠的自适应控温能力,合理选择石蜡参数和优化结构设计可改善控温性能,自适应控温冷板在地面电子设备及空间热载荷的控温领域有较好的应用前景。
To improve the temperature control reliability of spacecraft thermal control system, a self-adaption temperature control cold plate was designed based on the volume change characteristics of the paraffin wax due to the phase-change as its temperature changed. The design model of the self-adaption temperature control cold plate was built, and the thermal net model of the single phase fluid loop with the cool plate was given. The performance of the cold plate and the single phase fluid loop was analyzed. Results show that the cold plate designed has the ability of self-adaption temperature control, and it may be widely used in the temperature control for the electronic devices at ground and heat loads on spacecraft.
