| 摘 要： | 介绍了一种既可以实现快速启动又能够维持长时间小流量工作的锥形自调式J-T制冷器,可以广泛应用于制导导弹中红外焦平面探测器组件的制冷。该J-T制冷器采用微型波纹管作为自调机构,具有成本低、适应范围广等特点。与探测器杜瓦组件进行耦合试验,结果表明在50 MPa氩气气源条件下,芯片降温至100 K所需时间≤5 s。

| Abstract: | A conical self regulated J-T cryocooler is introduced.The cryocooler enables both fast start up and long periods of low flow operation,which can be widely used for cooling infrared focal plane detector components of guided missiles.The cryocooler adopts a miniature bellow as a self regulated mechanism,which has the characteristics of low cost and wide adaptability.Coupling tests with the detector Dewar assembly have shown that the chip cooling time to 100K is less than 5 s under the condition of 50 MPa Ar gas. |
