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

Abstract

This paper presents an improved design method and performance prediction of Stirling-type 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.
