    Lecture 19 Cryocoolers

    Lecture 19 Cryocoolers J. G. Weisend II Goals • Introduce the characteristics and applications of cryocoolers • Discuss recuperative vs. regenerative heat exchangers • Describe regenerator materials • Describe the Stirling cycle, Gifford McMahon and pulse tube cryocoolers and give examples June 2019 Cryocoolers - J. G. Weisend II Slide 2 Introduction to Cryocoolers • Cryocoolers are smaller closed cycle mechanical refrigeration systems – There is no official upper size for a cryocooler but typically these provide less than few 100 W of cooling at 20 – 100 K and less than 10 W at 4.2 K – Cryocoolers do not use the Claude/Collins cycles used by large refrigeration plants but use alternative cycles – Working fluid is almost always helium – some exceptions exist – All the laws of thermodynamics still apply – Improved technology ( bearings, miniaturized compressors, better materials, CFD, better reliability etc) has lead to the development of a large number of practical cryocooler designs in the past 10 – 20 years – We will concentrate on 3 types: Stirling, Gifford McMahon & Pulse tube June 2019 Cryocoolers - J. G. Weisend II Slide 3 Cryocooler Applications • Cryocoolers are most useful in applications that: – Have smaller heat loads ( < 1 kW) – Operate above 10 K (though there are significant 4.2 K applications) • Note synergy with HTS operating temperatures – Require small size, weight, portability or operation in remote locations – space and military applications – Are single cryogenic applications within a larger system – reliquefiers for MRI magnets, sample cooling, “cooling at the flip of a switch” June 2019 Cryocoolers - J. G. Weisend II Slide 4 Cryocooler Applications – Cooling of infrared sensors for night vision, missile guidance, surveillance or astronomy • Much IR astronomy requires < 3 K and thus can’t be met by cryocoolers – “Cryogen free” superconducting magnets or SQUID arrays – Reliquefing LN2,LHe or other cryogens – Cooling of thermal radiation shields – Cooling of HiTc based electronics e.g.

This technique is a very fundamental concept, especially for drying applications. By combining a solar thermal energy source such as solar thermal collectors and a heat pump dryer will assist in reducing the operation cost of drying and producing products with high quality. Many review papers in the literature evaluated the R&D aspects of solar-assisted heat pump dryers (SAHPD). This critical review paper studies some of the researches conducted in this field to understand and provides an update on recent developments in SAHPD.
