In simple words, by increasing retention time of fluids.
Other parameters which affect rate of heat transfer are:
1) Fins
2) Baffles
3) no. of passes.
4) Material of construction of tubes.
The factors that are affected by number of tubes in shell and tube heat exchanger is the rate of heat transfer and flow rate.
increase to heat transfer coefficent
Antony Johnson has written: 'Flow, heat transfer and pressure drop on the shell side of a shell and tube heat exchanger'
The assumption to design heat exchanger is that it must be a shell and tube device. This device must allow the transfer of heat from one fluid to another without mixing the two fluids.
double pipe heat exchanger is made if two concentric tubes one carrying cold flow and the other one carrying hot flow. but shell and tube hear exchangers are made of a shell like a vessel filled with many thin tubes to transfer heat between fluids. there are more data available at : http://scopewe.com/double-pipe-heat-exchanger-design-part-1/
**** you.......... pls somebody answer Double pipe heat exchanger consists of two concentric pipes of different diameters.One pipe is for hot fluid and another is for cold fluid.Both may have same flow direction(COCURRENT) and opposite direction(COUNTERCURRENT). Shell and tube heat exchanger consists of a shell in which large number of parallel tubes are present.One fluid hot or cold flow in shell and other hot or cold flow in the tubes. Also in case of shell & tube(S&T) the hot fluid will have more turbulence than in double pipe heat exchanger (HE) since there are no of tubes within a shell the area for convective heat transfer is considerably increased. so these are much more preferredTherefore the rate of heat transfer is greater in shell and tube because large surface area and enough contacting time

It's the flat, flanged cover on the front (and sometimes the rear) of a shell & tube heat exchanger.
the most effective way to do so is to reduce the flow of the heat exchanger
To passivate an exchanger gently pat the shell while whispering into a bleeder
A heat exchanger with straight tubes in a shell that can normally be mechanically cleaned
A split flow heat exchanger is a type of heat exchanger where the hot and cold fluids are split into multiple streams before being recombined. This design allows for more efficient heat transfer as it increases the surface area of contact between the two fluids. Split flow heat exchangers are commonly used in industrial processes where precise temperature control is required.
