Product Description

Shell and tube heat exchanger, as the name specified, consists of a shell and a number of tubes. Shell is the housing of the exchanger and tubes are mounted inside the cylindrical shell. It is the most widely used heat exchanger and are among the most effective means of heat exchange. 


Shell and tube heat exchanger is a device where two working fluids exchange heats by thermal contact using tubes housed within a cylindrical shell. The fluid temperature inside the shell and tube are different and this temperature difference is the driving force for temperature exchange. Used for wide temperature and pressure range, Shell and tube heat exchangers are compact in design, easy in construction and maintenance and provide excellent heat exchange.

Working Principle of Shell and Tube Heat Exchanger

The working of a shell and tube heat exchanger is fairly simple. One fluid flows inside the tubes and the other through the shell. While flowing they exchange the heats which means the cold fluid gains the heat from the hot fluid. So one cold fluid enters the shell (or tube side or channel side) inlet nozzle and comes out of the outlet nozzle as hot fluid. Obviously, the other fluid will become cold in the outlet than in the inlet. The heat transfer in a shell and tube heat exchanger is determined by the exposed surface area that is decided by the number of thermally conductive metal tubes. The fluid flow inside the shell and tube heat exchanger can be parallel flow or crossflow.



Basic Components of Shell and Tube Heat Exchanger
Typically a Shell and Tube Heat Exchanger consists of two-compartment / section one is shell side and other is channel/tube side

Shell side section consists of the following components: Shell, Cover, Body Flange, Nozzles, Saddle support.
Channel / Tube side section consists of the following components: Channel, Cover, Body Flange, Nozzles, Tube Sheet and Tubes  (Tube Bundle)

Shell and Tube Heat Exchanger is widely used in variety of application as a cooling solution. The most common among them is for cooling of Hydraulic Fluid and oil in engines, transmissions and hydraulic power packs. With the right coimbination of materials they can also be used to cool or heat other mediums, such as swimming pool water or charge air. One of the big advantages of using a shell and tube heat exchanger is that they are often easy to service, particularly with models where a floating tube bundle (where the tube plates are not welded to the outer shell) is available. 

They are commonly used in

space heating
refrigeration
air conditioning
power plants
chemical plants
petrochemical plants
petroleum refineries
natural gas processing
sewage treatment
