Abstract
A counter flow heat exchanger comprising a plurality of tubes disposed in a bundle array or tube within tube configuration to enhance heat transfer between high and low pressure tubes in the array or tube in tube configuration. Also disclosed are a method of increasing the heat transfer capacity of a tube bundle heat exchanger and a liquid helium temperature refrigerator or a reliquefier utilizing the heat exchanger.
Claims7
A heat exchanger of the type having a first confined path for conducting high pressure fluid from an inlet to a point wherein said high pressure fluid is expanded to a lower pressure and a second confined path for returning the expanded fluid from the point of expansion comprising in combination:
- a plurality of low pressure tubes and a plurality of high pressure tubes, said low pressure tubes and said high pressure tubes are of reduced diameter in a stepwise fashion or progressively flattened from end to end and arranged alternately in a bundle array.
