Shell and tube type heat exchanger designing

there are so many reference link for shell and tube exchanger. for designing u should know the basic of simple heat exchanger.

thanks for the suggestion but I am in touch of many books of heat exchanger designing . There are some gap between theoretical and practical things so I am asking for any suggestions for real time problems.

Difficult to offer suggestions unless more details are given. Have you looked at 'Heat Transmission' by McAdams? Is it a single pass or multipass? What are the fluids, temperatures, quantity of heat to be transferred, contaminations in the fluids, requirement of baffles and such data? Is it an academic exercise or a real life , to-be-built product?

it is a real time problem

Details are still needed.

Designing a shell and tube heat exchanger is easy as long as you have the right information. The exact type will generally depend on the manufacturer, for example the company I work for will offer straight tubes where as others offer a secondary surface (finned tube). Both types have their own advantages and disadvantages, which comes down to operational data and maximum allowable pressure drops etc.

In any case, to design a suitable heat exchanger you need to know what your putting into it, what you want to take out of it and what you have available to do that with. In other words;

Hot fluid Inlet temperature
Hot fluid flow rate
Required fluid outlet temperature (or heat dissipation in kW)

Cold fluid inlet temperature
Cold fluid flow rate

If you contact a manufacturer you also need to specify the fluid types as this will affect the performance and the materials which can be used.

For the best performance you need the coldest coolant possible, it's the same as imagining trying to cool down a drink. Using ice will cool it down better than just topping it up with cool water. A high flow rate is also good as this will take out more heat, but a flow rate which is too high can lead to erosion or a high pressure loss, but we advise our customers when this is likely to occur so I'm sure that other manufacturers will too.

I hope you found this information to be of use, any questions just let me know.
