摘要

亚开尔文吸附冷却器（SKSC）已成为一种可靠、无振动的空间低温解决方案，是一种极具竞争力的选择。本文的重点是开发一个 4He SKSC 原型，设计用于预冷绝热消磁制冷器（ADR）。根据吸附制冷机制，分析了工作介质量与冷却性能之间的关系。随后，对 SKSC 的每个组件进行了设计和建造，最终成功创建了 4He SKSC 原型。实验测试表明，它能够达到 773 mK 的最低温度，并在 803 mK 时提供 100 μW 的冷却能力。

Design and development of a 4He sub-Kelvin sorption cooler

The sub-Kelvin sorption cooler (SKSC) has emerged as a reliable and vibration-free solution for space cryogenics, establishing itself as a highly competitive choice. This paper focuses on the development of a ⁴He SKSC prototype designed for precooling an adiabatic demagnetization refrigerator (ADR). Based on the sorption refrigeration mechanism, the relationship between the amount of working medium and cooling performance is analyzed. Subsequently, each component of the SKSC is designed and constructed, resulting in the successful creation of a ⁴He SKSC prototype. Experimental testing demonstrates its capability to achieve a minimum temperature of 773 mK and provide a cooling capacity of 100 μW at 803 mK.
