www.sfu.caheat exchangers contain a large number of tubes packed in a shell with their axes parallel to that of the shell. Regenerative heat exchangers involve the alternate passage of the hot and cold fluid streams through the same flow area. In compact heat exchangers, the two fluids usually move perpendicular to each other.

operations.fnal.govHeat transfer occurs when objects, gasses, or fluids of different temperatures encounter each other. The modes of heat transfer are through conduction, convection, or radiation. Heat Exchanger There are many types of heat exchangers used in cryogenic systems. This discussion will limit itself to the types of heat exchangers used by the Main Ring
