近年来,气体驱动斯特林制冷机在比重量、可靠性、振动和噪声等方面得到提高,在红外技术和超导电子学等领域具有诱人的应用前景,其研究工作一直是低温领域的一个热点。首先简要描述了气动型斯特林制冷机气动腔内气体热力迟滞行为特性,其次主要理论推导该部分气体热力迟滞行为特性造成的损失,并且给出了一个计算机仿真结果说明该项损失对制冷机性能的影响。本文对更为逼真地仿真微型气动斯特林制冷机的热动力特性行为提供了有力支撑。 In recent years, the gas-driven Stirling refrigerator has been improved in terms of weight, reliability, vibration and noise, and has an attractive application prospect in the fields of infrared technology and superconducting electronics. The research work has always been in the field of low temperature A hot spot First of all, the gas thermal hysteresis behavior in the pneumatic cavity of a pneumatic Stirling refrigerator is briefly described. Secondly, the main theory is to deduce the loss due to the thermal hysteresis behavior of the gas, and a computer simulation result is given to show the effect of this loss on the refrigerating machine The impact of performance. This article provides a strong support for simulating the thermodynamic properties of micro-pneumatic Stirling refrigerators more vividly.
