摘要
Cryomech, Inc.与Industrial Research Ltd (IRL)合作，正在开发一种低成本的高频脉冲管制冷机。IRL开发的无阀压缩机采用了两个S.S.隔膜和一个新颖的运动驱动机构。脉冲管冷头具有同轴结构。与压缩机之间用1米长的SS软线隔开。试验结果表明，冷头的取向效应非常小(在任何方向都< 3k)。这种脉冲管制冷机为用户的集成提供了灵活性。在77K时可提供108W功率，初级试验输入功率3.7 kW。
DEVELOPMENT OF A LOW COST HIGH FREQUENCY PULSE TUBE CRYOCOOLER
In cooperation with Industrial Research Ltd (IRL), Cryomech, Inc. is developing a low cost high frequency pulse tube cryocooler. The valveless compressor, developed at IRL, employs two S.S. diaphragms and a novel kinematics driven mechanism. The pulse tube cold head has co-axial configuration. It is separated from the compressor with a SS flexible line of 1 meter long. The test results demonstrate a very small orientation effect of the cold head (<3 K at any orientation). This pulse tube cryocooler provides flexibility for user's integration. It can provide 108W at 77K with an electric input power of 3.7 kW in the primary test.
