Pulse Tube Refrigerator (PTR) is a special class of regenerative cryocooler where there is no moving part at the cold end. Due to this, it has inherent advantages of higher reliability, reduced vibrations and light weight. Based on the arrangement of regenerator and pulse tube in a PTR, there are various configurations possible like inline, U-shape...

This paper introduces our recent experimental results of pulse tube refrigerator driven by linear compressor. The working frequency is 23-30 Hz, which is much higher than the G-M type cooler (the developed cryocooler will be called high frequency pulse tube refrigerator in this paper). To achieve a temperature below 10 K, two types of two-stage con...

The focus of this work is the modeling and performance comparison of different models of pulse tube refrigerators, namely, the Orifice Pulse Tube Refrigerator (OPTR) and the Inertance-tube Pulse Tube Refrigerator (IPTR) with both in-line as well as coaxial configurations. A detailed analysis of the flow and heat transfer in various components of th...

Heat Transfer Analysis of 2-Stage G-M Cryocooler at 4 K Steady State Temperature for the Determination of its Capacity
Conference Paper

  • Feb 2017
A two stage Gifford-Mc Mahon Cryocoolers are used to produce ultra-low temperatures in the range of 4 K to 40 K in the cryogenics experimentations. Commercially available G-M Cryocoolers have wide range of cooling capacity. Heat transfer analysis has been carried out in the present study on the G-M Cryocooler at no load condition by considering exp...

... The theoretical and experimental performance with respect to various design and operating parameters for both inline and 'U' type configurations is compared [8]. It is also extended for the single-stage coaxial design [12]. The model is then further extended to design a two-stage pulse tube cryocooler with inline, integral arrangement. ...
