In some applications, the cool-down speed obtainable with a cryocooler is important besides the high efficiency at the working temperature. Because of the difference in configurations, the design and the control strategies for various cryocoolers may

DC flow may exist in a pulse tube cryocooler if a closed loop is formed by double inlet, etc. It has been found that, given the right amount and the right direction, DC flow may be favorable to the cooling performance of a PTC working at liquid hydro
