The invention discloses an ultra-stable thermal environment simulator for a spacecraft ground test, which adopts a layered structure, coatings with different emissivity are arranged on the inner surface and the outer surface of each layer, a plurality of radiators are uniformly arranged between the two outermost layers at intervals, the heat absorption surface of each radiator is arranged on the inner layer of the two outermost layers, and the heat absorption surface of each radiator is arranged on the outer layer of the two outermost layers. A heat dissipation surface of the ultra-stable thermal environment simulator penetrates through two outermost outer layers to be exposed outside, an active heat compensator is arranged in the middle of the ultra-stable thermal environment simulator, and each active heat compensator is used for adjusting the heat sink temperature of the ultra-stable thermal environment simulator and restraining thermal disturbance from the outside. Through optimization design, the temperature stability, uniformity and adjustability of the heat sink are improved, so that the thermal boundary simulation precision of the spacecraft assembly is remarkably improved, more accurate thermal management and temperature control are ensured to be realized in a harsh spaceflight environment, and the reliability and stability of spacecraft equipment are effectively guaranteed.

    本发明公开了一种用于航天器地面试验的超稳热环境模拟器,采用分层结构,每层的内外表面均设置有不同发射率的涂层,在最外面的两层之间均匀间隔设置有多个辐射器,每个所述辐射器的吸热面均设置在最外面两层中的内层,其散热面穿过最外面两层的外层裸漏在外,其中部均设置有主动热量补偿器,每个所述主动热量补偿器用于调节超稳热环境模拟器的热沉温度以及抑制来自外界的热扰动。本发明通过优化设计,提高了热沉的温度稳定性、均匀性和可调节性,从而显著提升航天器组件热边界模拟的精度,确保在严苛航天环境下实现更加精准的热管理与温控,有效保障了航天器设备的可靠性和稳定性。
