BRAZED PLATE

 A brazed plate heat exchanger (BPHE) is made up of several thin, corrugated metal plates that are permanently bonded together through a brazing process, usually using copper or nickel. Unlike gasketed heat exchangers, BPHEs do not use gaskets or external frames to hold the plates in place. Instead, the plates are fused into a single, compact, and sealed unit using high heat. Fluids pass through alternating pathways between the plates, enabling effective heat transfer between them. Due to their small size, strength, and ability to handle high pressures and temperatures, BPHEs are commonly found in HVAC, refrigeration, and various industrial systems
