Does the liquid inside the exchanger come in contact with the copper brazing material or only the stainless?

Hi Paul,
In a brazed plate heat exchanger (BPHE), the liquid flowing through the channels of the heat exchanger comes in contact with both the copper brazing material and the stainless steel plates.
Put simply, a brazed plate heat exchanger consists of multiple stainless steel plates that are stacked together, forming a series of alternating channels for the hot and cold fluids. The plates are typically brazed together using copper brazing material along the edges or contact points.
So during the brazing process, the copper brazing material melts and forms a seal, creating a tight and durable joint between the stainless steel plates. This brazing material also comes in contact with the fluid channels, as it fills the gaps between the plates.
And when the fluids flow through the channels, heat is transferred between them through the thin stainless steel plates. The copper brazing material acts as a conduit, helping to conduct heat from one plate to another.
Therefore, in a brazed plate heat exchanger, both the liquid and the brazing material come into contact with the stainless steel plates, while the fluid also comes into contact with the copper brazing material.
I hope this helps!😃

To melt the copper you have to go above the annealing temperature of the stainless. How do you avoid that?

BPHE tested to just ~4.5bar?
