A Brazed Heat Exchanger (BHE) is a compact and highly efficient heat transfer device designed to handle heating, cooling, evaporation, and condensing processes in various industrial and HVAC applications. It consists of multiple thin, corrugated stainless-steel plates that are vacuum-brazed together with copper or nickel, creating a durable, leak-proof structure without the need for gaskets. This design allows for excellent thermal performance, high pressure and temperature resistance, and reduced fouling compared to traditional heat exchangers. BHEs are widely used in refrigeration systems, heat pumps, district heating, and process industries due to their space-saving design, energy efficiency, and long service life with minimal maintenance requirements.
