Reasons For Heat Exchanger

What are the reasons for Heat Exchanger ?

I have Mentioned here Reasons For Corrosion in Heat Exchanger ?

Reasons for Corrosion in Heat Exchanger are :-

1.Sea Water :- Corrosion by Sea Water may Occasionally Cause perforation of Heat Transfer surfaces with resultant Leakage of one Fluid into the other.

2.Air in the cooler system will encourage corrosion and air locks will reduce the cooling area and cause Overheating.

3.Sometimes,due to water hammer due to Rapid acceleration or deceleration of any Liquid.

4.Corrosion on the tube due to the thermal fatigue (accumulated stresses related to Constant thermal cycling ).

5.Thermal Expansion
