A heat-exchanger system consisting a bundle U tubes (hairpin tubes) surrounded by a shell (outer vessel); one fluid flows through the tubes, & the other fluid flows through the shell, around the tubes.Multitherm can duplicate any existing bundle to include dimensions, materials & performance. we can build "U" tube bundles, straight tube "floating" tube bundles, or we can retube fixed tubesheet heat exchangers when the bundles is not removable. multitherm is not locked into any one material. Most bundles tend to be build with copper tubes & steel tubesheets.This refers to the number times the fluid in the tubes passes through the fluid in the shell. In a single pass heat exchanger, the fluid goes in one end each tube & out the other. A tube bundle heat exchanger with baffles is disclosed wherein a tube bundle is housed within an inner casing which is acted upon from both the inside & the outside by a heating medium. In nuclear power plants called pressurized water reactors, large heat exchangers called steam generators are two-phase, shell-&-tube heat exchangers which typically have U-tubes. They are used to boil water recycled from a surface condenser into steam to drive a turbine to produce power. Most shell-&-tube heat exchangers are either 1, 2, or 4 pass designs on the tube side.
Applications & Uses:-
The simple design a shell & tube heat exchanger makes it an ideal cooling solution for a wide variety applications. One the most common applications is the cooling Hydraulic Fluid & oil in engines, transmissions & hydraulic power packs. With the right choice materials they can also be used to cool / heat other mediums, such as swimming pool water or charge air. One the big advantages using a shell & tube heat exchanger is that they are ten easy to service, particularly with models are floating tube bundle (where the tube plates are not welded to the outer shell) is available. Can also be used on fixed tube sheet heat exchangers.
