Abstract
The invention relates to a heat exchanger, particularly a counter-flow heat exchanger for use in a Joule-Thomson refrigerator. The heat exchanger includes a casing having at least one pipe disposed therein which defines a first flow passage for conducting a first fluid. A second flow passage is provided between the pipe and the casing for conducting a second fluid in heat transfer relationship with the first fluid. A plurality of wire nets are provided along each of the two flow passages to facilitate heat transfer between the two respective fluids.
Claims7
A heat exchanger comprising:
- an elongated casing;
- first cap means for closing a first end of said casing;
- second cap means for closing a second end of said casing, opposite said first end;
- first plate means connected in said casing adjacent said first end for defining a first chamber with said first cap means;
- second plate means connected in said casing adjacent said second end for defining a second chamber with said second cap means, and a third chamber being thereby defined between said first and second plate means;
- one of a first inlet and a first outlet connected to each of said first and second chambers;
- a second inlet and a second outlet connected to said third chamber;
- a first plurality of wire nets free of spacers therebetween and arranged in a densely packed stack at a minimum separation distance in said third chamber;
- a plurality of conduit means extending through said first wire nets and through said first and second plate means for conducting fluid between said first and second chambers;
- a second plurality of wire nets free of spacers therebetween and arranged in a densely packed stack at a minimum separation distance in each of said conduit meansa
- plug means for densely packing the second plurality of wire nets over a predetermined distance within said conduit means;
- and
- first and second bosses for densely packing the first plurality of wire nets over a distance within said third chamber corresponding to said predetermined distance.
