叙述了气体低温机活塞传热损失的研究方法和试验装置。发表了试验数据,指出了低温机一些主要结构参数对损失值的影响。对试验数据与计算数据作了比较,表明两者有令人满意的一致性。提出了减少气体低温机活塞传热损失的方法。
The research methods and test equipment for the heat transfer loss of the piston in gas cryogenic machine are described. Published experimental data, pointed out that some of the main structural parameters of the cryogenic machine on the loss value. A comparison of the experimental data with the calculated data shows that there is a satisfactory agreement between the two. A method to reduce the heat transfer loss of piston in gas cryogenic machine is proposed.
