Document Type and Number:
WIPO Patent Application WO/2016/155601
Kind Code:
A1
Abstract:
A refrigerator comprises a regenerator (4), a cold heat exchanger (5), a pulse tube (6), a warm heat exchanger (7) and a phase modulating mechanism (9), respectively sequentially connected. A drainage tube (17) is disposed inside the regenerator (4) axially and extends inside the cold heat exchanger (5). The drainage tube (17) further extends inside the pulse tube (6) and the warm heat exchanger (7). The refrigerator can realize uniformity of fluid flow in the refrigerator and prevent bias-flow, and particularly reduce nonuniform temperature inside the regenerator (4), realizing efficient operation of the refrigerator.
