US 2016/0109183 A1 · MULTIPATH CROSS FLOW HEAT EXCHANGER

Abstract

The present invention relates to a multipath cross flow heat exchanger and, more particularly, to a multipath cross flow heat exchanger, capable of preventing degradation of the cooling performance for cooling a superconductor which may occur when circulation of liquid nitrogen in a circulation tube is not efficient, by forming a cooling tube, in which a refrigerant for cooling liquid nitrogen flows, to intersect multiple times with the circulation tube, in which the liquid nitrogen is circulated, to thereby freeze the liquid nitrogen by the refrigerant.

Claims8

Dependent claims

A multipath cross flow heat exchanger comprising:

a circulation tube in which cooling fluid for cooling a superconducting cable flows;
and
a cooling tube defining a flowing path intersecting the circulation tube multiple times and in which a refrigerant that exchanges heat with the cooling fluid flows.

Dependencies are inferred from the claim text.
