5. Classification
Based on Nature
of Heat Exchange
Process

6. i) Direct Contact
Exchangers

7. ii) Recupreators

8. iii) Regenerators

9. 2. Classification Based On Flow And
Construction Of Heat Exchanger

10. i) Parallel flow of heat exchangers
In parallel flow of heat exchangers
the hot and cold fluids with a
large temperature difference enter
the heat exchanger from the same
end and flow parallel to each
other.

11. ii) Counter flow
of heat
exchangers

13. iii) Cross flow of heat exchangers

15. Application of heat exchangers
Heat exchanger are found mostly in chemical or mechanical systems .
They serve as the system's means of gaining or rejecting
heat.
Some of the more common applications are,Refrigerators.
Power plants and in petrochemical plants
. Heating , ventilation and Air Conditioning systems
. Radiators in internal combustion engines
. Boilers and condensers
. Pre-heaters or coolers in fluid systems
. High performance aircraft gas turbine engines.
