This is an advantage that brazed plate HXs have, because of their close plate spacing and opposing herringbone pattern, turbulence is assured. They also have an advantage of large surface area for their size, and lastly, with the exception of the outer surface of the outside plates, all surfaces are engaged in transferring heat.
