论文摘要
这项研究开发了一种新型的热控制系统，以在飞行前冷却一般反颗粒光谱仪（GAP）的探测器。间隙是气球传播的宇宙射线观察实验。在其有效载荷中，差距包含1000多个硅检测器，必须冷却以下$ -40^{\ circ} \ mbox {c} $。所有探测器都热耦合到独特的热管系统（HPS），该系统将热量从探测器传输到散热器。散热器设计为在$ -50^{\ circ} \ mbox {c} $下进行冷却，通过暴露于太空。检测器的飞行前状态在1 atm和环境室温下在地面上检查，但散热器不能类似冷却。作者开发了一个接地冷却系统（GCS），以冷却探测器以进行地面测试。 GC由冷板，一个冷却器和绝缘泡沫组成。冷板设计为连接到散热器，并由冷却器泵送的冷却液冷却。包括HP在内的有效负载配置可以与飞行的配置相同。使用刻度模型通过热测试对GCS设计进行了验证。 GCS设计很简单，提供了实用的指南，包括简单地估算适当的热绝缘厚度，可以轻松地适应其他应用。
This study developed a novel thermal control system to cool detectors of the General AntiParticle Spectrometer (GAPS) before its flights. GAPS is a balloon-borne cosmic-ray observation experiment. In its payload, GAPS contains over 1000 silicon detectors that must be cooled below $-40^{\circ}\mbox{C}$. All detectors are thermally coupled to a unique heat-pipe system (HPS) that transfers heat from the detectors to a radiator. The radiator is designed to be cooled below $-50^{\circ}\mbox{C}$ during the flight by exposure to space. The pre-flight state of the detectors is checked on the ground at 1 atm and ambient room temperature, but the radiator cannot be similarly cooled. The authors have developed a ground cooling system (GCS) to chill the detectors for ground testing. The GCS consists of a cold plate, a chiller, and insulating foam. The cold plate is designed to be attached to the radiator and cooled by a coolant pumped by the chiller. The payload configuration, including the HPS, can be the same as that of the flight. The GCS design was validated by thermal tests using a scale model. The GCS design is simple and provides a practical guideline, including a simple estimation of appropriate thermal insulation thickness, which can be easily adapted to other applications.
