Choosing a reasonable area of heat exchanger can avoid too many or too few total plates.

Too many heat exchanger plates will make the equipment cover too large area;

Too little may increase the number of processes and increase the pressure drop;

At the same time, the size of the sheet area is also related to the size of the Angle hole to a certain extent, which directly affects the flow rate and velocity of the heat exchanger.
