Step-by-step design methodology for efficient Stirling-type pulse tube refrigerator

摘要

This paper presents an improved design method and performance prediction of Stirlingtype pulse tube refrigerator (PTR). The paper is composed of three parts and each content is as follows: 1) specific design and fabrication of each component, 2) modeling and configuration optimization of Stirling-type PTR, and 3) experimental verification. Each part provides a step-by-step procedure to easily understand the design process for developers and researchers who want to develop efficient Stirling-type PTRs. Through this proposed design process, an efficient Stirling-type PTR is carefully designed for cooling capacity of 8 W at 50 K. The fabricated Stirling-type PTR possesses the cooling capacity of 7 W at 50 K and the Carnot efficiency of 11.7% at 56.3 K. The experimental results show the proposed design methodology fulfills the required performance of Stirling-type PTR with desirable accuracy. The design process presented in this paper can help developers and researchers to design an efficient Stirling-type PTR.
