چکیده

Pulse tube cryocooler has low vibration and high reliability because of the lack of displacer in the cold area. This advantages cause development of this cryocoolers. In some applications such as MRI systems which need cryocoolers for cooling magnet, using them will improve the imaging quality.In this article, the steps of designing a pulse tube cryocooler which is able to be installed in MRI systems will be introduced. As conceptual design is a vital section of any design project, this part has been totally studied; Necessary data has been gathered and developed in order to have best function in the pulse tube system. Preliminary design with help of two analyses (Phasor and Isotherm analysis) is introduced to designers and important parameters are obtained. Then investigation the effect of some design parameters like valve timing, reservoir volume and pressure ratio by using isothermal analysis has been done on cryocooler performance.

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
