Cryogenic refrigeration system

Abstract

Provided is a cryogenic refrigeration system. The cryogenic refrigeration system includes a cryogenic refrigerator, and a heat dissipation module configured to cool the cryogenic refrigerator. Here, the heat dissipation module includes a condenser configured to condense a refrigerant that cools the cryogenic refrigerator, and a heat exchanger connected to the cryogenic refrigerator to circulate the refrigerant between the cryogenic refrigerator and the condenser, thereby cooling the cryogenic refrigerator.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This U.S. non-provisional patent application claims priority under 35 U.S.C. §119 of Korean Patent Application No. PCT / KR2015 / 004044, filed Apr. 23, 2015, the entire contents of which are hereby incorporated by reference.TECHNICAL FIELD[0002]The present invention disclosed herein relates to a cryogenic refrigeration system, and more particularly, to a cryogenic refrigeration system capable of improving a coefficient of performance thereof.BACKGROUND ART[0003]In general, a cryogenic refrigerator may be used to cool a superconductor or a small-sized electronic component. For example, the cryogenic refrigerator may include a stifling refrigerator, a GM refrigerator, and a Joule-Thomson refrigerator. The above-described cryogenic refrigerator may generate refrigeration output through an expansion process of working fluid such as helium or hydrogen. The expansion process may accompany heat generation of a compression process. Accordingly, the ...

AI Technical Summary

Benefits of technology

The cryogenic refrigeration system described in this patent improves its efficiency by using refrigerant which has a higher coefficient of performance and heat absorption than water. This increases the amount of heat that can be removed by the refrigerator, making it more efficient. The refrigerator is also directly cooled by a heat dissipation module, which reduces operational costs.

Problems solved by technology

The water-cooling type heat dissipater may be cooled by the vapor compression refrigerator However, since the water-cooling type heat dissipater uses water that has a low cooling efficiency of performance, a coefficient of performance of the cryogenic refrigerator may be reduced.

In addition, the water-cooling type heat dissipater and the vapor compression refrigerator may increase costs for operating the cryogenic refrigerator to reduce productivity.
