The Infrared Focal Plane Array (IRFPA) detector needs quite low dark noise for image detection. It can be cooled to demanding low temperature by pulse tube cooler (PTC) because of low vibration and low electromagnetic interference (EMI) at cold end. A high-capacity pulse tube cooler driven by a moving-magnet linear compressor is presented in this paper. The regenerator and pulse tube are arranged in coaxial. The inertance tube and reservoir are used as passive phase shifter of the PTC. A numerical thermodynamic model is established to design and optimize overall performance of the pulse tube cold finger aimed for the best efficiency. Based on the principle of electric-mechanical-acoustic coupling field, a transient co-simulation of the PTC is proposed. The mass of the PTC is less than 12 kg without electronic controller. The oscillating linear compressor has a pair of opposite pistons to eliminate vibration and the input electric input power is 400 W at maximum. A typical cooling performance of 50 W at 170 K has been achieved with 228 W input power at reject temperature of 293 K, provided by water cooling. The specified Carnot efficiency is 15.8%. Additionally, overall cooling performances of the PTC at 150K-200 K are investigated by experiment, Not only could this PTC be used for space mission but also a promising alternative to the domestic low temperature applications.

研制出以170K运行的星载脉冲管冷却器

红外焦平面阵列(IRFPA)检测器需要非常低的暗噪声进行图像检测。由于在冷端的低振动和低电磁干扰(EMI),可通过脉冲管冷却器(PTC)将其冷却到要求的低温。本文提出了一种由动磁铁线性压缩机驱动的大容量脉冲管冷却器。蓄热器和脉冲管同轴布置。惯性管和储液器用作PTC的无源移相器。建立了数值热力学模型,以设计和优化旨在获得最佳效率的脉冲管冷指的总体性能。基于机电声耦合原理,提出了PTC的瞬态协同仿真方法。不带电子控制器的PTC重量小于12千克。振荡线性压缩机具有一对相对的活塞,以消除振动,并且输入电输入功率最大为400W。在水为293 K的情况下,利用228 W的输入功率在293 K的拒绝温度下,可以实现170 W时50 W的典型冷却性能。指定的卡诺效率为15.8%。此外,还通过实验研究了PTC在150K-200 K时的总体冷却性能。该PTC不仅可以用于太空飞行,而且还是家用低温应用的有希望的替代品。指定的卡诺效率为15.8%。此外,还通过实验研究了PTC在150K-200 K时的总体冷却性能。该PTC不仅可以用于太空飞行,而且还是家用低温应用的有希望的替代品。指定的卡诺效率为15.8%。此外,还通过实验研究了PTC在150K-200 K时的总体冷却性能。该PTC不仅可以用于太空飞行,而且还是家用低温应用的有希望的替代品。
