Abstract

The ⁴He Joule-Thomson cryocooler (JTC) ensures the operation of space detectors working within the 4 K temperature range, such as the Block Impurity Band Infrared Detector (BIBID). In addition, the ⁴He JTC is one of the essential components of the 300 K to 50 mK space cryochain. It can precool sub-Kelvin refrigerators, such as the adiabatic demagnetization refrigerator (ADR) and the dilution refrigerator (DR). With the development of space science, the need for cooling power at the 4 K temperature range is growing. Thus, a thermal performance model of the ⁴He JTC precooled by a two-stage thermally coupled pulse tube cryocooler (PTC) is designed, manufactured, and tested with an eye toward space applications. A four-stage compression system with a high operating frequency and large pistons is designed and used to drive the JT cycle. This ⁴He JTC has a total mass of 55 kg and can provide a cooling capacity of 105 mW at 4.41 K with a total input electric power of 548 W.

为空间应用设计的 105 [email protected] K 4He 焦耳-汤姆逊低温冷却器的热性能模型

4He 焦耳-汤姆逊低温冷却器（JTC）确保了在 4 K 温度范围内工作的空间探测器（如块状杂质带红外探测器（BIBID））的运行。此外，4He 低温冷却器是 300 K 至 50 mK 空间低温链的重要组成部分之一。它可以预冷亚开尔文制冷器，如绝热消磁制冷器（ADR）和稀释制冷器（DR）。随着空间科学的发展，对 4 K 温度范围内制冷功率的需求日益增长。因此，我们设计、制造并测试了由两级热耦合脉冲管低温冷却器（PTC）预冷的 4He JTC 热性能模型，并将目光投向了空间应用。设计并使用了一个具有高工作频率和大活塞的四级压缩系统来驱动 JT 循环。这种 4He JTC 的总重量为 55 千克，在 4.41 K 时可提供 105 mW 的冷却能力，总输入电功率为 548 W。
