回热器是斯特林制冷机冷头的重要组成部分。传统的回热器使用接触式滑动密封, 存在磨损, 限制制冷机的使用寿命。
间晾密封的应用则可以在完成密封作用的同时消除接触磨损和因此而产生的污染。但由于间隙内气体的泄漏, 引起了冷损
失, 使制冷减少建立了间晾密封式斯特林制冷机回热器密封间晾泄诵率的数学物理模型, 推导了密封间原的泄漏率及泄漏
引起的冷童损失的表达式
- Abstract:
-
The regenerator is a key part of the cold head of Stirling refrigerator. Traditionally, the seal be? tween the regenerator and cylinder wall has been accomplished using sliding bearings,but there was contact and wear in the bearings. The results was that the working life of Stirling refrigerator was limited. The method of clearance seal can achieve the effect of the seal between regenerator and cylinder wall while elim? inating contact between them. Thus it eliminates wear and another source of wear in the refrigerator. But, the gas leakage of clearance seal leads to the leakage losses and the reduction of the cooling power. The pa? per establishes the mathematical and physical model of the leakage of the clearance seal in Stirling refriger? ator with clearance seals,and describes a set of equations of the leakage and the leakage losses of the clear? ance seal.
