Design and Development of A Pulse Tube Cryocooler
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 5
Abstract
NASA planned few Mars missions in between 2012 to 2018. This mission requires very compact maintenance free, long life cryocooler for production and storage of cryogenic fluid on Mars. The main moving component of cryocooler is linear motor and we have to design it very precisely to give good overall efficiency and long maintenance free life. So an attempt is made to carry out parametric analysis of motor available in lab. It was shown that the linear motor efficiency for available design increases by 4% approx. Based on this outcome, a new linear motor compressor is manufactured for different capacity pulse tube cryocooler with enhanced operational efficiency and similarly by playing with different parameters of pulse tube and regenerator we developed a cold head also to suit for the compressor.
