極低温冷凍機および極低温システム
Document Type and Number:
Japanese Patent JP7265363
Kind Code:
B2
Abstract:
A cryocooler includes an attachment flange including a refrigerant gas introduction port through which refrigerant gas is introduced into a recondensing chamber from an ambient temperature environment, and attachable to the recondensing chamber, and a cooling stage that is disposed inside the recondensing chamber when the attachment flange is attached to the recondensing chamber. The refrigerant gas introduction port is perpendicularly or obliquely oriented with respect to an axial direction of the cryocooler so that a refrigerant gas flow exiting the refrigerant gas introduction port deviates from the cooling stage.
