MIT Brazed Plate Heat Exchangers can be designed with plates having different heat transfer charecteristics.
The H Type plate obtuse angles which result in higher heat transfer efficieny by increasing the turbulence of the fluid.
The L Type plate has acute angles. This reduces the pressure drop and leads to reduced turbulence and lower heat transfer efficieny
The M Type plate is a combination of L and H plates. This solution can be used for applications, where the temperature change on one side of the BPHE is much larger than on the other.
