Paper Abstract

Presented in this paper are the test results of the engineering test model of integrated cooler experiment. This cooler consists of integrating a small, low-power Stirling cryogenic refrigerator with a small mass of a triple point phase change material (PCM). The advantages of this type of cooler are a closed system; no vibrations during sensor operation; the ability to absorb increased 'spike' heat loads; potentially longer system lifetime; and a lower mass, cost, and power consumption. Experimentation was performed in the laboratory using methanol as the PCM. The goals of the testing were to demonstrate the practical use of new technologies and demonstrate the operation of the total system for simulated sensor scenarios. Presented are the results of the first series of tests.
