HORIZONTAL FINNED HEAT EXCHANGER FOR CRYOGENIC RECONDENSING REFRIGERATION |
摘要 |
A cryogenic system includes a superconducting magnet (20) in a reservoir of liquid helium (LH). Helium vapor (VH) rises and contacts a recondenser surface (50, 50′, 50″) on which the helium vapor (VH) condenses into liquid helium and flows by gravity off a lower edge of the recondenser surface. A plurality of fins (52) extend from the recondenser surface or a plurality of grooves (52′, 52″) are cut into the recondenser surface to disrupt the film thickness and to provide a path by which droplets of the liquid helium leave the recondenser surface without travelling a full vertical length of the recondenser (30). |
