Pulse Tube Refrigeration is a new refrigeration method which was conceived by W. E. Gifford in 1961.
This refrigerator can make a low temperature without any mechanical devices, actually, a temperature of 26°K has already been achieved with a LN2 cooling single stage refrigerator and a 43°K with 4 stage refrigerator.
The interest in the method is due to the fact that, though the phenomenon is very complex and difficult to analyze, the equipment of a Pulse Tube Refrigerator can be very small and simple.
The notes that have been assembled here try to give a basic understanding of the surface heat pumping mechanism, its characteristics, advantages and limitations.
These should provide enough information for making a decision regarding the development of Pulse Tube Refrigerator.
