Please explain if there is heat transfer present within an adiabatic heat exchanger.

Solution

Yes, there is heat transfer present \"within\" an adiabatic heat exchanger.

Adiabatic, here refers that no net heat transfer is taking place through the boundaries of heat exchanger.

That is no heat is going in or out across the external boundary of the heat exchanger.

But, Internally heat exchange is happening between two or more fluids entering and leaving the system (Adiabatic H.E.).
