在理论研究及实验论证的基础上,本文提出了一种新型的低温回热式气体制冷机。理论计算和实验证明此机器能按要求的工作规律正常工作,工作性能良好,运动机构简单,冲击力小,此机构有两个压缩腔和两个膨胀腔,机构左右对称,工作时类似于Solvay循环。此机的特点是汽缸的左右两部分机构串连一体,工作时互相利用他缸的热腔,组成波动腔,取代了Solvay机的中间波动腔,汽缸两端同时输出冷量,使机器的结构大大简化,且省略了一部分辅助设备,并为汽缸中双活塞过渡到单活塞提供了良好的基础,最终消除穿梭损失。此外,该机上配备了一种新研制的磁力封油结构,基本上解决了机器上油问题,改善了制冷机的工作性能。另外,为了改善换热性能,采用了间隙换热和铜丝网组成的蓄冷器。
On the basis of theoretical research and experimental demonstration, this paper presents a new type of low temperature regenerative gas refrigerator. Theoretical calculations and experiments show that this machine can work normally according to the required working rules, work well, the movement mechanism is simple, impact force is small, the mechanism has two compression chambers and two expansion chambers, the mechanism is symmetrical, work is similar to Solvay cycle. This machine is characterized by the cylinder around the two parts of the mechanism in series, working with each other to use his cylinder’s hot chamber, the composition of the wave chamber, replacing the Solvay machine fluctuations in the middle of the chamber, both ends of the cylinder at the same time output cold, so that the structure of the machine Greatly simplifies and omits some of the auxiliary equipment and provides a good basis for the twin pistons to transition to a single piston in the cylinder, ultimately eliminating shuttle losses. In addition, the machine is equipped with a newly developed magnetic oil seal structure, basically solved the oil machine problems, improve the performance of the refrigerator. In addition, in order to improve the heat transfer performance, the use of gap heat transfer and copper wire composed of regenerator.
